If electronic installation determines the network of communication service MP in step 403 supports IMS agreement, then electronic installation carry out step 405, and wherein, in described step 405, electronic installation uses MP to provide IMS service.Such as, when being provided communication service by LTE network, the IMS service controller 224 of the AP 103 in Fig. 2 drives second media engine 242 of MP 105, the 2nd IMS protocol stack 244 and TCP/IP 246.Then, MP 105 uses the second media engine 242, the 2nd IMS protocol stack 244 and TCP/IP 246 to provide IMS service.Like this, electronic installation does not provide MP and AP of the network of communication service to reduce power consumption by cutting out.
On the contrary, if electronic installation determines the network of communication service MP in step 403 does not support IMS agreement, then electronic installation carry out step 409, and wherein, in described step 409, electronic installation uses AP to provide IMS service.Like this, electronic installation does not provide the MP of the network of communication service to reduce power consumption by cutting out.
In step 407, whether electronic installation determination communication network changes.Such as, whether electronic installation determination electronic installation is switched to eHRPD network from LTE network.
