  • GPRS General Packet Radio Services
  • EDGE Enhanced Data rates for GSM Evolution
  • WCDMA Wideband Code Division Multiple Access
  • HSDPA High-Speed Downlink Packet Access
  • HSDPA achieves the increase in the data transfer speeds by defining a new transport channel: a high-speed downlink shared channel (HS- DSCH) that operates in a different way from existing WCDMA channels and is used for downlink communications to the mobile.
  • HS- DSCH high-speed downlink shared channel
  • Other standards such as CDMA and Long Term Evolution (LTE) have or will potentially have other sub-standards. As stated above, all these standards may exist overlapping within an area served by an operator and the operator of such a combined network of different standards is faced with the problem of having to manage the resources within the combined network in a way that both maximizes the use of the combined resources and maximizes the service provided to each mobile user within the combined network.
  • a multi-access capable mobile In order to always be able to attach to a most appropriate access technology, a multi-access capable mobile must also monitor all the accesses for performing measurements/identification. That however excessively drains the battery in mobile stations (MS) thus deteriorating the standby-time performance. As there arc today no efficient mechanisms to save the battery if multi-access scenario embraces standards developed in different bodies, e.g. GSM/WCDMA by 3GPP and WLAN by IEEE, it is also reflected in the battery consumption, which becomes very high indeed.
  • an MS is performing both monitoring of 2G/3G cells and WLAN cells in order to connect to WLAN when applicable.
  • 2G/3G monitoring has been designed for battery saving monitoring, the monitoring of WLAN is unnecessarily adding extra battery consumption, especially when assuming that WLAN has far worse coverage.
  • radio access technologies providing coverage only at some spots of a geographical area co-exist with radio access technologies having a broad coverage in the same geographical area.

  • the system depicted in Fig. 1 comprises two different radio access technologies deployed within the same geographical area. It is understood that additional radio access technologies can be deployed along side the two radio access technologies shown in Fig. 1 , but to simplify the Figure only two radio access technologies are shown.
  • the radio access technologies may for example be a GSM system comprising cells 101 and WLAN cells 103 deployed at hot spots within the GSM network.
  • the system and method as described herein is not limited to any particular radio access technologies and the cells 101 and 103 could equally well correspond to WCDMA, LTE, WiMAX or any other technology providing radio access.
  • Fig.l will continuously monitor all the radio access technologies that it supports to try to find the best way of access when moving around within the geographical area.
  • the mobile station can be instructed not to activate monitoring of WLAN until signaled to activate WLAN monitoring by the network.
  • the network should have as good knowledge as possible of where WLAN coverage exists.
  • the network is provided with precise and updated knowledge of the WLAN coverage mapped onto the cellular one.
  • the information about the WLAN coverage mapping onto the cellular one can be obtained by performing regular cell-selection measurements with separate equipment at each WLAN access point location. This information about the macro cell that embraces the coverage of the particular WLAN access point is then stored by the network.
  • every WLAN access point can be provided with a measurement capability for macro cells in the area such as GSM/WCDMA in order to regularly perform a cell-reselection procedure using identical algorithm as a regular mobile station.
  • the WLAN access point instead of registering itself in the network the WLAN access point can be adapted to signal to the network through its own backhaul, the information about the "macro cell" that has best radio coverage in accordance with the performed cell reselection procedure performed.
  • the network can always have the accurate information about where in the network a particular WLAN access point is located.
  • the information collected and sent to the network can typically include: WLAN access point identity and network identity (SSID), macro cell base station identity (BSID) and possibly its own location such as coordinates established via a Global Positioning System (GPS), if available.
  • SSID WLAN access point identity and network identity
  • BSID macro cell base station identity
  • GPS Global Positioning System
  • the information collected using any of the methods above or any other suitable method can be stored into the O&M databases and than used to signal to the mobile station when the mobile station is located in an area where it is possible that WLAN coverage can be obtained as determined by the information stored in the O&M system. Such a method is depicted in Fig. 2.
  • step 201 information relating to the WLAN is first transmitted to the network, step 201.
  • the information relating to all access points received is stored in a memory of the network, step 203.
  • the network transmits an activation signal to the mobile station signaling the existence of WLAN access points in the area where the mobile station is present, step 205.
  • the signaling message to the mobile station should preferably be a standardized message to be standardized.
  • the system checks if and if there are access points present in that cell/location area for that mobile station to access by referring to the information stored about access points and transmitting that information back to the mobile station. It is then up to the mobile station to activate the WLAN monitoring if deemed needed, e.g. the mobile station recognizes its home access point that it wants to attach to by default. When WLAN monitoring activated, the mobile station can proceed with regular WLAN attach procedures.
  • a flow chart illustrating different steps performed in a mobile station (MS) when receiving radio access information from a radio network is shown.
  • the mobile station receives a message from the radio network that the cell where the mobile station currently is present has at least one WLAN access point deployed that the mobile station may want to connect to.
  • the mobile station may or may not enable WLAN monitoring.
  • Activation of WLAN monitoring can be dependent on a number of parameters.
  • the parameters may be user configurable. For example the mobile station can be configured to only monitor WLAN if close to its home access point or it may be configured to always search for WLAN access points regardless of location. This is performed in step 303.
  • the radio network When the mobile station continues to travel the radio network continuously transmits new information corresponding to the current location of the mobile station. Thus, if the mobile station enters a cell where no WLAN access is possible the radio network informs the mobile station by signaling such information to the mobile station, which then can deactivate WLAN monitoring to save battery consumption.
  • the method and system are particularly power saving when monitoring radio access technologies being of a spotty nature such as a WLAN or other similar radio access technologies, where large parts of a geographical area is not covered by that radio access technology.
  • the access points can be equipped with a device corresponding to a receiver of a mobile station, such as a GSMAVCDMA receiver, which will keep the cost low and not causing any additional load in the cellular network.
