[0037] 步骤S100,获取终端上报的终端位置信息,查询关联数据库获取各WLAN热点的热点位置信息,根据所述终端位置信息和各所述WLAN热点的热点位置信息,计算所述终端与各所述WLAN热点之间的距离最小值; [0037] step S100, obtain the terminal location information terminal reporting, query relational database to obtain position information of each hot spot WLAN hotspot, hotspot location information based on the terminal position information and each of the WLAN hotspots, calculating the terminal with the WLAN hotspots distance between said minimum;

[0038] 步骤S102,判断所述距离最小值是否小于预设距离门限值,若小于所述预设距离门限值则进入步骤S104; [0038] step S102, the determination of the minimum distance is less than a preset distance threshold, if the distance is less than the preset threshold value the process proceeds to step S104;

[0039] 步骤S104,判断所述距离最小值对应的WLAN热点的策略状态是否为允许所述终端接入,若所述WLAN热点的策略状态为允许所述终端接入,则进入步骤S106 ; [0039] step S104, the minimum value is determined from the corresponding status WLAN hotspot policy whether to permit the access terminal, if the policy for the state of the WLAN hotspots allow the terminal access, the process proceeds to step S106;

[0040] 步骤S106,下发切换策略信息至所述终端。 [0040] step S106, the switching strategy issued information to the terminal.

[0041] 具体地,蜂窝网络和WLAN间的无缝切换装置中包含关联数据库,关联数据库中存储全网的WLAN热点的热点位置信息,热点位置信息为标示WLAN热点地理位置的信息。 [0041] Specifically, seamless switching device between cellular networks and WLAN contained relational database, hotspot location information stored in the database associated with the entire network of WLAN hotspots, hotspot location information is marked geographic information WLAN hotspots. 终端上报终端位置信息至该装置,终端位置信息为标示终端所在地理位置的信息。 Reported by a terminal position information to the terminal device, terminal location information terminal location information where indicated. 该装置获取终端上报的终端位置信息后,开启蜂窝网络和WLAN间的无缝切换操作,具体包括: After this means obtains terminal position information reported by the terminal, open seamless handover operations between cellular networks and WLAN, including:

[0042] 查询关联数据库,获取各WLAN热点的热点位置信息,根据终端位置信息和各WLAN热点的热点位置信息,计算该终端与各WLAN热点之间的距离,反馈距离最小值,然后判断该距离最小值是否小于预设距离门限值。 [0042] query relational database, obtain position information of each hot spot WLAN hotspot, hotspot location information based on the terminal position information and various WLAN hotspots, which calculates the distance between the terminal and the respective WLAN hotspot, the feedback from the minimum value, and then determine the distance the minimum is less than the preset distance threshold. 由于终端和WLAN热点之间进行通信的过程中,信号强度会随着距离的增加而加速衰减,因此当终端和WLAN热点之间的距离过大时,终端与WLAN热点之间无法进行正常通信。 Due process between the terminal and WLAN hotspots for communication, the signal strength increases as the distance accelerate decay, so that when the distance between the terminal and the WLAN hotspot is too large, can not communicate properly between the terminal and WLAN hotspot. 距离最小值小于预设距离门限值表示终端周围存在可正常通信的WLAN热点。 Less than a preset distance from the minimum threshold value indicates the presence of WLAN hotspots around the terminal can communicate properly.

[0043] 在优选的实施例中,预设距离门限值为100米。 [0043] In a preferred embodiment, the predetermined distance threshold is 100 meters.

[0044] 当WLAN热点处于重负载时,终端再接入WLAN热点后进一步加重该WLAN热点的负载,容易造成终端通信不畅,掉话等情况。 [0044] when WLAN hotspots in heavy load, further aggravated after the terminal, and then connected to the WLAN hotspot WLAN hotspots load, likely to cause poor communication terminal, dropped calls and so on. 网络侧系统根据WLAN网络中WLAN热点的负载情况,实时更新WLAN热点的策略状态,当某一个WLAN热点的负载超过预设值时,即将该WLAN热点的策略状态更改为不允许新的终端接入。 The network side of the system according to the load WLAN hotspot WLAN network, real-time updating policy status WLAN hotspot, a WLAN hotspot when a load exceeds a preset value, the WLAN hotspot is about policy status is changed to allow new terminal access .

[0045] 因此当终端周围存在距离较近的WLAN热点时,需要进一步判断距离该终端最近的WLAN热点的策略状态是否为允许所述终端接入,若允许则下发切换策略信息至终端,切换策略信息包括距离最小值对应的WLAN热点的WLAN热点信息,如热点ID。 [0045] Therefore, when there is a short distance of WLAN hotspots around the terminal, the terminal needs to further determine the distance of the nearest WLAN hotspot policy status whether to allow access to the terminal, if the permit is issued to switch the policy information to the terminal, switch WLAN hotspots policy information includes information corresponding to the minimum distance of WLAN hotspots, such as the hot spot ID. 终端根据切换策略信息,开启WLAN搜索,接入距离该终端最近的WLAN热点,完成蜂窝网到WLAN网络的切换。 Terminal switching strategy based on information, open WLAN search, access to the terminal from the nearest WLAN hotspot, complete cellular network to WLAN network switch.

[0046] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端位置信息,查询关联数据库获取全网WLAN热点的热点位置信息,根据终端位置信息和热点位置信息判断距离终端最近的WLAN热点是否在预设距离门限值的范围内,若是则进一步判断距离终端最近的WLAN热点是否允许终端接入,如果允许则下发切换策略信息至该终端,通知该终端开启WLAN搜索,接入该WLAN热点。 Technical Solution [0046] In this example, the seamless switching device between cellular networks and WLAN access hotspot location information of the whole network WLAN hotspots by acquiring the terminal end position information, query relational databases, information based on the terminal position information and hotspot locations judging from the terminal within the nearest WLAN hotspot is in range of the preset distance threshold, if it is further judged from the end nearest WLAN hotspots allow terminal access, if allowed to switch the policy information is issued to the terminal to notify the terminal Open WLAN search, access to the WLAN hotspot. 实现了网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,从而提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,进一步地,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 To achieve a network-side intelligence judgments, switching strategy to develop information notification terminal access WLAN hotspots, thereby improving the utilization of WLAN networks to reduce the load pressure on the cellular network, and further, since the switching policy information was developed by the network side, so Users do not need cumbersome terminal side switch setting, simplifying user operation.

[0047] 在优选的实施例中,通过后台短信通道下发切换策略信息至所述终端。 [0047] In a preferred embodiment, by a background send SMS channel switching policy information to the terminal.

[0048] 通过后台短信通道下发切换策略信息,既不需要更改现有信令通道的传输协议,又不会使用户产生GPRS流量费用。 [0048] Hair switched by SMS channel strategy under the background information, it does not require changes to existing signaling channel transport protocol, and not leave the user to generate GPRS traffic costs.

[0052] 步骤S204,查询关联数据库获取各WLAN热点的热点位置信息,根据所述终端位置信息和各所述WLAN热点的热点位置信息,计算所述终端与各所述WLAN热点之间的距离最小值; [0052] step S204, the query relational database to obtain position information of each hot spot WLAN hotspot, hotspot location information based on the terminal position information and each of the WLAN hotspots, calculating the distance between each of the terminal WLAN hotspots minimum value;

[0056] 具体地,蜂窝网络和WLAN间的无缝切换装置获取到终端上报的终端位置信息后,首先判断终端所处的蜂窝网小区的小区负载是否大于预设小区负载门限值,若小于预设小区负载门限值则说明该终端目前所处的蜂窝网小区负载较轻,无需切换至WLAN网络,若大于预设小区负载门限值则说明该终端目前所处的蜂窝网小区负载较重,需要切换至WLAN网络。 [0056] In particular, the seamless handover between WLAN devices and cellular network access to the terminal position information reported by the terminal, the first to determine the cell in which cellular network terminal load cell is the cell load is greater than a preset threshold, if less than cell load preset threshold value it indicates that the terminal is currently enjoying a light load cell cellular network, without having to switch to a WLAN network, if the load cell is greater than a preset threshold value it indicates that the terminal is currently enjoying cell load than the cellular network weight, we need to switch to WLAN networks.

[0057] 当蜂窝网小区的负载较重时,该装置启动蜂窝网络和WLAN间的无缝切换操作,具体切换操作与第一实施例中相应步骤相同。 [0057] When the cell is heavily loaded cellular network, the device is activated seamless handover operations between cellular networks and WLAN, specific switching operation of the first embodiment, the same as the corresponding steps.

[0058] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置获取终端的终端位置信息后,首先判断终端所在的蜂窝网小区是否处于重负载,若是则启动切换操作,将该终端从负载较重的蜂窝网小区切换至负载较轻的WLAN网络中。 [0058] The technical solution of the present embodiment, the seamless handover between WLAN devices and cellular network after acquiring the terminal location information of the terminal, the terminal first determines whether the cell where the cellular network in a heavy load, if the switching operation is initiated, the terminal from a heavily loaded cellular network to a lightly loaded cell WLAN networks. 从而实现了网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,进一步地,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Enabling the network side intelligence judgments, switching strategy to develop the utilization of information notifying terminal access WLAN hotspots, improved WLAN networks to reduce the load pressure on the cellular network, and further, since the switching policy information was developed by the network side, so Users do not need cumbersome terminal side switch setting, simplifying user operation.

[0066] 步骤S308,判断所述距离最小值对应的WLAN热点的策略状态是否为允许所述终端接入,若所述WLAN热点的策略状态为允许所述终端接入,则进入步骤S310,若所述WLAN热点的策略状态为不允许所述终端接入,则流程结束; [0066] step S308, the minimum value is determined from the corresponding status WLAN hotspot policy whether to permit the access terminal, if the policy for the state of the WLAN hotspots allow the terminal access, the process proceeds to step S310, if Policy status of the WLAN hotspot for the terminal access is not allowed, then the process ends;

[0067] 步骤S310,下发切换策略信息至所述终端。 [0067] step S310, switching strategy issued information to the terminal.

[0068] 具体地,终端上报终端位置信息,其中终端位置信息包括终端GPS模块上报的终端经纬度信息。 [0068] Specifically, the terminal position information reported by the terminal, wherein the terminal position information including latitude and longitude information terminal GPS module terminal reported. 蜂窝网络和WLAN间的无缝切换装置获取终端GPS模块上报的终端经纬度信息后,查询关联数据库,其中关联数据库中包括各WLAN热点的热点经纬度。 After seamless switching device between cellular networks and WLAN access terminal GPS module terminal reported the latitude and longitude information, query relational database, relational database which includes the latitude and longitude of each WLAN hotspot hotspot. 获取全网的各WLAN热点的热点经纬度,根据终端经纬度信息和各WLAN热点的热点经纬度,计算得到终端和各WLAN热点之间的距离,反馈距离最小值。 Get all WLAN hotspots whole network of hotspots latitude and longitude, the latitude and longitude information according to the terminal and the latitude and longitude of each WLAN hotspot hotspot, the calculated distance between the terminal and the respective WLAN hotspot, the feedback from the minimum.

[0069] 步骤S306、S308以及S310和上述实施例中的相应步骤流程相同。 [0069] step S306, the same as S308 and S310 and the above embodiments corresponding steps processes.

[0070] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端经纬度信息,根据终端经纬度信息和热点经纬度判断终端周围是否有允许其接入的WLAN热点,制定切换策略信息。 [0070] This embodiment of the technical solution, seamless switching device between cellular networks and WLAN terminal by acquiring the latitude and longitude information terminal, according to the latitude and longitude information terminals and hot spots around the terminal latitude and longitude to determine whether there are allowed to access WLAN hot spots, to develop switching policy information. 由此实现通过网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Thereby achieving intelligent judgment by the network side, switching strategy to develop information notifying terminal access WLAN hot spots, improve the utilization of WLAN networks to reduce the load pressure on the cellular network, since the information is switching strategy developed by the network side, so no terminal cumbersome user side switch setting, simplifying user operation. 进一步地,由于GPS模块上报的终端经纬度信息精准度高,因此网络侧能够根据终端经纬度准确寻找到终端周围的WLAN热点,提高了终端切换的成功率。 Further, since the GPS module terminal latitude and longitude information reported high accuracy, so the network side can accurately find the latitude and longitude based on end-to-end around the WLAN hot spots, improve the success rate of the terminal switching.

[0073] 进一步地,终端位置信息还包括所述终端所在蜂窝网小区的小区ID,所述关联数据库中还包括各蜂窝网小区的小区ID以及小区经纬度信息,该方法步骤S304之前还包括: [0073] Further, the terminal location information terminal further comprises a cellular network where a cell a cell ID, the database associated with the cell ID and the cell further comprises a latitude and longitude information of each cell in the cellular network, the method further comprises before step S304:

[0074] 步骤S312,判断所述终端经纬度信息是否无效,若所述终端经纬度信息无效,则进入步骤S314,若所述终端经纬度信息有效,则进入步骤S304 ; [0074] step S312, the terminal judges the latitude and longitude information is not valid, if the terminal latitude and longitude information is not valid, the process proceeds to step S314, if the terminal is the latitude and longitude information is valid, the process proceeds to step S304;

[0077] 具体地,终端上报终端位置信息至蜂窝网络和WLAN间的无缝切换装置,其中终端位置信息包括终端经纬度信息和终端所在蜂窝网小区的小区ID。 [0077] Specifically, the terminal reported terminal location information to the cellular network and the WLAN switch seamlessly between devices, wherein the terminal position information including latitude and longitude information terminal and the terminal of the cell where the cellular network cell ID. 该装置首先判断终端经纬度信息是否有效,当终端没有GPS模块或终端位于无GPS信号区域时,上报的终端位置信息中终端经纬度信息无效。 The device first determines the latitude and longitude information terminal is valid, when the terminal is not GPS module or no GPS signal terminals are located in the region, the reported location information terminal end latitude and longitude information is invalid. 当终端经纬度信息无效时,根据终端上报的小区ID来判断终端所在的地理位置。 When the terminal is invalid latitude and longitude information, according to the cell ID reported by the terminal to determine the geographic location of the terminal.

[0078] 根据小区ID查询关联数据库,关联数据库中包括各WLAN热点的热点经纬度、各蜂窝网小区的小区ID以及小区经纬度信息,获取终端所在小区的小区经纬度信息。 [0078] According to the cell ID database query association, including the associated database WLAN hotspots hotspots latitude and longitude, latitude and longitude of the cell ID and the cell information of each cell of a cellular network, access to the terminal where the cell-cell latitude and longitude information. 根据小区经纬度信息和各WLAN热点的热点经纬度,计算出终端所在的蜂窝网小区和各WLAN热点之间的距离,并反馈距离最小值。 According cell latitude and longitude information and latitude and longitude of each WLAN hotspot hotspot, calculate the distance where the cellular network terminal and each cell between WLAN hotspots, and feedback from the minimum. 当终端位置信息中的终端经纬度信息有效时,则优先选择根据终端经纬度信息和各WLAN热点的热点经纬度来计算终端和各WLAN热点之间的距离。 When the terminal position information in latitude and longitude information terminal is valid, the preferred terminal according to the latitude and longitude information and latitude and longitude of each WLAN hotspots hotspots to calculate the distance between the terminal and the respective WLAN hotspot.

[0079] 由于GPS模块上报的终端经纬度信息精确度很高,因此当终端上报的经纬度信息有效时,优先根据终端经纬度信息来确定终端的位置。 [0079] Since the GPS latitude and longitude information terminal module reported a high degree of precision, so when the terminal reported the latitude and longitude information is valid, according to the terminal priority information to determine latitude and longitude location of the terminal. 但部分终端上没有GPS模块,或当终端进入无GPS信号的区域时,存在终端无法上报终端所在地的经纬度的情况。 But not on the part of the terminal GPS module, or when no GPS signal terminal enters an area, there is a case where the terminal the terminal can not be reported latitude and longitude location. 因此当终端上报的终端经纬度信息无效时,以小区经纬度补充确定终端的位置,从而实现了在终端通过GPS定位失败时还可以通过其他方式获得可用的终端位置信息。 So reported the terminal when the terminal is invalid latitude and longitude information to supplement the cell latitude and longitude position determination terminal, enabling the terminal via GPS, can have failed to obtain the terminal location information available through other means.

[0089] 步骤S416,下发切换策略信息至所述终端。 [0089] step S416, switching strategy issued information to the terminal.

[0090] 具体地,蜂窝网络和WLAN间的无缝切换装置中的热点状态数据库中存储全网WLAN热点的策略状态,该装置根据预设周期采集全网WLAN热点的参数信息,并根据WLAN热点的参数信息获得WLAN热点的策略状态,定时更新热点状态数据库中每个WLAN热点的策略状态,具体方法如下: [0090] In particular, the seamless handover between WLAN and cellular network devices in the database stored in the hot state status of the whole network policy WLAN hot spots, which means the whole network WLAN hotspots acquisition parameter information according to a preset period, and according to WLAN hotspots The parameter information obtained WLAN hotspots policy status, hotspot state policy status regularly updated database of every WLAN hotspots, as follows:

[0091 ] 该装置与各WLAN AC通信连接,各WLAN AC根据预设的采集粒度采集接入WLAN热点的总用户数、接入WLAN热点的用户中正在使用业务的业务用户数以及业务类型,WLAN AC根据预设周期将上述参数发送至蜂窝网络和WLAN间的无缝切换装置,预设周期等于WLANAC的采集粒度。 [0091] This means connecting the WLAN AC communicate with each WLAN AC according to a preset collection size collection total number of users access to WLAN hotspots, access user WLAN hotspots in the number of users and business operations of the types of services being used, WLAN AC according to a preset cycle transmits the parameters to the seamless handover between WLAN devices and cellular networks, the default period is equal WLANAC collection size. 根据各业务类型所占网络资源的大小设定各业务类型的业务权重值,例如根据各业务类型所占的网络带宽或所需的承载速率来设定各业务类型的业务权重值。 According to various business types share network resources business size setting weights for each type of business, for example, based on the share of each type of business or the required network bandwidth bearer rate to set the weight value of each business type of business.

[0092] 根据总用户数和WLAN热点的拟覆盖面积,计算用户密度,用户密度等于总用户数与拟覆盖面积的比值。 [0092] According to the proposed coverage of the total number of users and WLAN hotspots, user density computing, user density equal to the ratio of the total number of users and the intended coverage area. 根据业务用户数和总用户数,计算业务渗透率,业务渗透率等于业务用户数和总用户数的比值。 According to business users and the total number of users to calculate the service penetration, service penetration rate is equal to the ratio of the number of users and the total number of business users. 根据业务权重值和接入WLAN热点的用户所使用的业务类型计算WLAN热点的总业务权重。 WLAN hotspots calculated according to the type of business user traffic weights and access WLAN hotspots are using the weight of the total business.

[0093] 根据影响WLAN热点负载的因素预设三个门限值,包括预设密度门限值、预设渗透率门限值以及预设权重门限值。 [0093] According to a preset load factors WLAN hotspots three threshold values, including the default density threshold, permeability preset threshold, preset weight threshold. 对WLAN热点的上述参数和预设的三个门限值进行比较,从而确定该WLAN热点的策略状态,其中策略状态分为允许终端接入和不允许终端接入,进一步设置允许终端接入为1,不允许终端接入为O。 WLAN hotspots on the above parameters and preset three threshold values to determine the status of the WLAN hotspot strategy, which is divided into state policy allows terminal access and do not allow terminal access, further setting allows the terminal to access the 1, does not allow access to the terminal O. 具体判断方法如下: To determine the specific methods are as follows:

[0094] 判断用户密度是否大于预设密度门限值,若不大于预设密度门限值则说明该WLAN热点接入的用户总数较少,因此将WLAN热点的策略状态设为允许所述终端接入;若大于预设密度门限值则说明该WLAN热点接入的用户总数较多。 [0094] determine whether the user density is greater than a preset threshold density, if the density is greater than the preset threshold then the less the total number of users of the WLAN hotspot, so the policy status WLAN hotspots to allow the terminal access; if the density is greater than a preset threshold then the user of the total number of WLAN hotspots more.

[0095] 进一步判断业务渗透率是否大于预设渗透率门限值,若不大于预设渗透率门限值,则说明该WLAN热点中正在使用业务的用户数量较少,因此将WLAN热点的策略状态设为允许所述终端接入;若大于预设渗透率门限值,则说明该WLAN热点中正在使用业务的用户 [0095] Further operational permeability is greater than a preset determination threshold permeability, if the permeability is greater than the preset threshold value, then the fewer the number of users in the WLAN hotspot service being used, so the WLAN hotspot strategy status to allow the terminal to access; when more than a preset penetration threshold, it indicates that the WLAN hotspot business users is being used

数量较多。 A larger number.

[0096] 进一步判断总业务权重是否大于预设权重门限值,若不大于预设权重门限值则说明该WLAN热点中虽然使用业务的用户数较多,但该用户所使用的业务需要的网络资源较小,因此将WLAN热点的策略状态设为允许所述终端接入,若大于预设权重门限值则说明该WLAN热点使用业务的用户数较多,且所使用业务需要的网络资源较多,因此将WLAN热点的策略状态设为不允许所述终端接入。 [0096] further determine the weight of the total business is greater than a preset threshold weight, if not larger than the preset threshold then the weights, although the number of users using the WLAN hotspot business more, but the users are using business needs smaller network resources, so the policy status WLAN hotspots to allow the terminal to access, if the weight is greater than a preset threshold then the number of users using the WLAN hotspot business more, and the use of network resources to business needs more, so the policy status WLAN hotspot to the terminal access is not allowed.

[0097] 在优选的实施例中,当用户密度大于预设密度门限值且业务渗透率大于预设渗透率门限值时,周期性计算该WLAN热点的总业务权重,如果连续三次出现总业务权重大于预设权重门限值,则将该WLAN热点的策略状态设为不允许所述终端接入。 [0097] In a preferred embodiment, when the user density is greater than a preset threshold value and service penetration density greater than the preset penetration threshold, the periodic calculation of the total business of the WLAN hotspot weight appear if three consecutive overall Business weight is greater than a preset threshold weight, then the policy status WLAN hotspot to the terminal access is not allowed.

[0098] 蜂窝网络和WLAN间的无缝切换装置的热点状态数据库中存储全网WLAN热点的策略状态,并定时更新每个WLAN热点的策略状态。 [0098] hot state database seamlessly switch devices between cellular networks and WLAN in the whole network storage policy status WLAN hotspots, and regularly update the policy status of each WLAN hotspot. 当终端上报终端位置信息至该装置后,该装置经过计算获得距离终端最近的WLAN热点后,查询热点状态数据库中该WLAN热点的策略状态,并判断该WLAN热点的策略状态是否为运行终端接入,若是则下发切换策略信息至终端。 When the terminal is reported after the terminal position information to the means calculated from the terminal through the nearest WLAN hotspot hotspot state database query policy status in the WLAN hotspot, and determine the status of the WLAN hotspots strategy to run the terminal access , if it is issued to switch the policy information to the terminal. 其中步骤S410至步骤S416和上述实施例中相应步骤的流程相同。 In which the same step S410 to step S416 and the above-described embodiments, the steps of the process. [0099] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端经纬度信息,根据终端经纬度信息和热点经纬度判断终端周围是否有允许其接入的WLAN热点,并进一步制定切换策略信息。 [0099] This embodiment of the technical solution, seamless switching device between cellular networks and WLAN terminal by acquiring the latitude and longitude information terminal, according to the latitude and longitude information terminals and hot spots around the terminal latitude and longitude to determine whether there are allowed to access WLAN hotspots, and Further development of switch policy information. 由此实现通过网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Thereby achieving intelligent judgment by the network side, switching strategy to develop information notifying terminal access WLAN hot spots, improve the utilization of WLAN networks to reduce the load pressure on the cellular network, since the information is switching strategy developed by the network side, so no terminal cumbersome user side switch setting, simplifying user operation. 进一步地,由于GPS模块上报的终端经纬度信息精准度高,因此网络侧能够根据终端经纬度准确寻找到终端周围的WLAN热点,提高了终端切换的成功率。 Further, since the GPS module terminal latitude and longitude information reported high accuracy, so the network side can accurately find the latitude and longitude based on end-to-end around the WLAN hot spots, improve the success rate of the terminal switching.

[0100] 进一步地,步骤S414后还包括: [0100] Further, after the step S414 further includes:

[0101] 若WLAN热点的策略状态为不允许所述终端接入,则进入步骤S418 ; [0101] If the policy status WLAN hotspot for the terminal access is not allowed, the process proceeds to step S418;

[0102] 步骤S418,判断与终端距离小于预设距离门限值的其他WLAN热点的策略状态是否为允许所述终端接入,若其他WLAN热点的策略状态为允许所述终端接入,则进入步骤S416,若其他WLAN热点的策略状态为不允许所述终端接入,则流程结束。 [0102] step S418, judgment and other WLAN hotspots terminal distance is less than a preset threshold value of the policy from the state whether to allow access to the terminal, if the policy status of the other WLAN hotspots to allow the terminal access, then enter step S416, if the policy status of the other WLAN hotspot for the terminal access is not allowed, then the process ends.

[0103] 具体地,当距离终端最近的WLAN热点的策略状态为不允许终端接入时,说明该WLAN热点处于重负载,对该WLAN热点临近的其他WLAN热点的策略状态进行判断,如果其他WLAN热点的策略状态为允许终端接入,临近的其他WLAN热点处于轻负载,下发切换策略信息至终端,通知终端接入临近的其他WLAN热点。 [0103] In particular, when the policy status from the terminal nearest WLAN hotspot not to allow terminal access, indicating that the WLAN hotspot in a heavy load, the policy status WLAN hotspots near other WLAN hotspots judge, if the other WLAN policy status hotspots to allow terminal access, other neighboring WLAN hotspots in light load, switching strategy issued information to the terminal, other WLAN hotspots notification terminal access nearby.

[0104] 当最近的WLAN热点处于重负载时,将新请求接入终端调度到临近的处于轻负载的其他WLAN热点,从而起到WLAN网络负载均衡的作用。 [0104] When the nearest WLAN hotspot in heavy load, the new terminal scheduling requests access to other neighboring WLAN hotspots in light load, which play the role of WLAN network load balancing.
