As shown in figure 4, when electronic device includes multiple MP, whether electronic device supports IMS agreements to provide according to MP IMS service.
Fig. 4 is the flow chart for the method for offer IMS service in MP of exemplary embodiment according to the present invention.
With reference to Fig. 4, in step 401, electronic device determines the network for providing communication service using AP.For example, work as When electronic device includes LTE MP and enhanced high-speed rate grouped data (eHRPD) MP, electronic device determines electricity according to priority Whether sub-device can provide communication service by LTE network.When determining that communication service can not be provided by LTE network, electronics Device determines whether eHRPD can be used to provide communication service for electronic device.
In step 403, electronic device determines whether the MP of the network for communication service supports IMS agreements.
If electronic device determines that the MP of the network for communication service supports IMS agreements, electronic device in step 403 Step 405 is carried out, wherein, in the step 405, electronic device provides IMS service using MP.For example, when passing through LTE nets When network provides communication service, the second media engine 242 of the driving of IMS service controller 224 MP 105 of the AP 103 in Fig. 2, 2nd IMS protocol stacks 244 and TCP/IP 246.Then, MP 105 uses the second media engine 242, the 2nd IMS protocol stacks 244 IMS service is provided with TCP/IP 246.In this way, electronic device can not provide the MP and AP of the network of communication service by closing To reduce power consumption.
On the contrary, if electronic device determines that the MP of the network for communication service does not support IMS agreements in step 403, Electronic device carries out step 409, wherein, in the step 409, electronic device provides IMS service using AP.It is in this way, electric Sub-device can reduce power consumption by closing the MP for the network for not providing communication service.
In step 407, electronic device determines whether communication network changes.For example, whether electronic device determines electronic device EHRPD network is switched to from LTE network.
If electronic device determines that communication network changes in step 407, electronic device is again true back to electronic device Whether the MP of the network after fixed change supports the step 403 of IMS agreements.
On the contrary, if electronic device determines that communication network does not change in step 407, electronic device terminates this processing. For example, while the communications service is being provided, electronic device provides IMS service using MP or AP.
As discussed above, when switching between two MP, AP can be used to provide the IMS of MP clothes in electronic device Business.In this case, the IMS protocol stacks of MP should be synchronous with the IMS protocol stacks of AP and be linked.For example, when entering LTE network When, electronic device provides IMS service using LTE MP.When electronic device is switched to eHRPD network, LTE MP will be used for The necessary information (such as, session information) of IMS service is sent to the IMS protocol stacks of AP.The use received from LTE MP can be used in AP IMS service is kept by eHRPD network in the necessary information of IMS service.In this way, it ought not perform to check LTE network During the communication protocol of channel condition, electronic device can reduce power consumption by closing LTE MP.
Fig. 5 is the data for the offer IMS service in the MP of electronic device of exemplary embodiment according to the present invention Flow diagram.
Include IMS agreement, video engine and the audio engine identical with the IMS agreements that AP includes with reference to Fig. 5, the first MP, And the 2nd MP does not support IMS agreements.

When communication service is provided by using the first MP for supporting IMS agreements, AP can drive the TCP/ of the first MP IP, IMS library and media engine.
TCP/IP, IMS library and media engine can be used to provide IMS service for first MP.For example, in order to provide audio call Service, the first MP set calling by SIP signalings.In next step, the first MP processing is used for the voice data of voice call service, So as to provide voice call service by PS networks.In addition, the first MP performs periodic session during voice call service Refresh.In this way, AP and the 2nd MP can be turned off to reduce the power consumption of electronic device.The voice call service provided by PS networks It is serviced including ip voice (VoIP).
For example, in order to provide video call service, the first MP is set by SIP signalings and called.In next step, the first MP processing For the video data and voice data of video call service, so as to provide video call service by PS networks.In addition, first MP performs periodic session refreshing during video call service.In this way, AP and the 2nd MP can be turned off to reduce electronics dress The power consumption put.
In this way, when the first MP supports IMS agreements, the first modulation /demodulation transceiver of the first MP is included for will be from physics The data that layer receives are classified and are routed to the data router in sufficient path.For example, data router is based on packet count Classify according to the type of network (PDN) and carrier (bearer) to data.For example, data router can pass through analyzing IP packet Head classify to data.Data are divided into IMS data and non-IMS data, and IMS data be divided into signaling and Multi-medium data.At this point, data router may be implemented in the modulation /demodulation protocol stack of the first modulation /demodulation transceiver, Huo Zheke It is implemented separately.For example, in LTE system, data router may be implemented in Packet Data Convergence Protocol (PDCP) layer or It is implemented separately based on PDCP.
Therefore, when the first MP supports IMS agreements, IMS data and IMS signal can be sent to the first MP by data router TCP/IP, and non-IMS data are sent to corresponding application by the TCP/IP for passing through AP.
When communication service is provided by using the 2nd MP for not supporting IMS agreements, AP can provide IMS service.Example Such as, in voice call service, AP can set calling by SIP signalings.In next step, AP can handle what is received by the 2nd MP Audio data, so as to provide voice call service.
For example, for video call service, AP can set calling by SIP signalings.In next step, AP can be handled by The video data and audio data that two MP are received, so as to provide video call service.
In the case where being switched to the 2nd MP from the first MP, the first MP will be for necessary information (such as session of IMS service Information) the IMS protocol stacks of AP are sent to synchronous with the IMS protocol stacks of AP and link.Therefore, AP can be used for from the first MP The necessary information of the IMS service of offer keeps IMS service.
