In the following description, it is assumed that the application processor 103 and the modem processor 105 provide IMS services using at least one IMS protocol and TCP / IP stored in respective internal memories.

As shown in FIG. 2, the application processor 103 controls to provide a multimedia service using at least one software program. For example, the application processor 103 includes an application layer 200, a library layer 220, and a framework layer 210. In this case, the application processor 103 may further include various components in addition to the illustrated components.

As described above, the application processor 103 includes an IMS protocol set 1 for processing IMS data, and the modem processor 105 includes an IMS protocol set 2 244 for processing IMS data. At this time, IMS protocol set 1 and IMS protocol set 2 244 include all the IMS protocols required for the IMS service.

3 illustrates a procedure for providing an IMS service in the MP according to the first embodiment of the present invention.

Referring to FIG. 3, in step 301, the electronic device determines whether a communication service can be provided through a network using an application processor (AP). For example, the electronic device determines whether a communication service can be provided through a Long Term Evolution (LTE) network.

If the communication service can be provided, the electronic device proceeds to step 303 to provide an IMS service using a modem processor (MP). For example, when providing a communication service through an LTE network, the IMS service control unit 224 of the application processor 103 illustrated in FIG. 2 may use the media engine 2 242 and the IMS protocol set 2 of the modem processor 105. 244 and TCP / IP 246 are driven. The modem processor 105 then provides IMS services using media engine 2 242, IMS protocol set 2 244 and TCP / IP 246. In this case, the electronic device may reduce power consumption by powering off the application processor.

Thereafter, the electronic device ends this algorithm.

If the electronic device includes a plurality of modem processors, the electronic device may provide an IMS service according to whether the modem processor supports the IMS protocol as shown in FIG. 4.

4 illustrates a procedure for providing an IMS service in an MP according to a second embodiment of the present invention.

Referring to FIG. 4, the electronic device determines a network for providing a communication service using an application processor (AP) in step 401. For example, if the electronic device includes an LTE modem processor and an enhanced High-Rate Packet Data (eHRPD) modem processor, the electronic device first determines whether the communication service can be provided through the LTE network according to the priority. If the communication service cannot be provided through the LTE network, the electronic device determines whether the communication service can be provided through the eHRPD.

After determining the network for providing the communication service, the electronic device proceeds to step 403 to determine whether the modem processor of the network for providing the communication service supports the IMS protocol.

If the modem processor of the network for providing the communication service supports the IMS protocol, the electronic device proceeds to step 405 to provide the IMS service using the modem processor (MP). For example, when providing a communication service through an LTE network, the IMS service control unit 224 of the application processor 103 illustrated in FIG. 2 may use the media engine 2 242 and the IMS protocol set 2 of the modem processor 105. 244 and TCP / IP 246 are driven. The modem processor 105 then provides IMS services using media engine 2 242, IMS protocol set 2 244 and TCP / IP 246. In this case, the electronic device may reduce power consumption by powering off an application processor and a modem processor of a network that does not provide a communication service.

Meanwhile, if the modem processor of the network for providing the communication service does not support the IMS protocol, the electronic device proceeds to step 409 to provide the IMS service using the application processor (AP). In this case, the electronic device may reduce power consumption by powering off the modem processor of the network that does not provide a communication service.

In addition, the electronic device proceeds to step 407 to check whether the communication network is changed. For example, the electronic device determines whether to handover from the LTE network to the eHRPD network.

If the communication network is changed, the electronic device proceeds to step 403 and checks whether the modem processor of the changed communication network supports the IMS protocol.

On the other hand, when the communication network is changed, the electronic device terminates the present algorithm. That is, the electronic device provides an IMS service using a modem processor or an application processor while providing a communication service.

As described above, when a handover occurs between two modem processors, the electronic device may provide an IMS service provided by the modem processor to the application processor. In this case, the IMS protocol set of the modem processor and the IMS protocol set of the application processor should be synchronized and interworked. For example, when connected to an LTE network, the electronic device provides an IMS service using an LTE modem processor. If the electronic device hands over to the eHRPD network, the LTE modem processor transmits information required for the IMS service, such as session information, to the IMS protocol set of the application processor. The application processor may maintain the IMS service through the eHRPD network by using information required for the IMS service provided from the LTE modem processor. At this time, the electronic device may reduce power consumption by deactivating the LTE modem processor except for a section for performing a communication protocol for checking a channel state of the LTE network.

5 illustrates a data flow for providing an IMS service in the MP of the electronic device according to the first embodiment of the present disclosure.

As shown in FIG. 5, the first modem processor includes the same IMS protocol and video engine and audio engine as the application processor, and the second modem processor does not support the IMS protocol.

When the electronic device includes a plurality of modem processors, the application processor determines a communication network for providing a communication service.

When providing a communication service using a first modem processor that supports the IMS protocol, the application processor runs the TCP / IP, IMS library, and media engine of the first modem processor.

The first modem processor provides an IMS service using TCP / IP, an IMS library, and a media engine. For example, when providing a voice call service, the first modem processor establishes a call via SIP signaling. Thereafter, the first modem processor processes the audio data for the voice call service to provide the voice call service through the PS network. In addition, the first modem processor performs a session refresh procedure that is periodically performed during a voice call service. In this case, the application processor and the second modem processor may be deactivated to reduce power consumption of the electronic device. Here, the voice call service provided through the PS network includes a Voice of Internet Protocol (VoIP) service.

In another example, when providing a video call service, the first modem processor establishes a call through SIP signaling. Thereafter, the first modem processor processes video data and audio data for a video call service and provides a video call service through a PS network. In addition, the first modem processor performs a session verification procedure periodically performed during the video call service. In this case, the application processor and the second modem processor may be deactivated to reduce power consumption of the electronic device.

As described above, when the first modem processor supports the IMS protocol, the first modem transceiver of the first modem processor is configured to route a data router that distinguishes data provided from the physical layer and routes it to an appropriate path. Include. For example, the data router classifies each data according to a packet data network (PDN) and a bearer. As another example, the data router may analyze the header of the IP packet to distinguish each data. Here, data is divided into IMS data and non IMS data, and IMS data is divided into signaling and multimedia data. In this case, the data router may be implemented in a modem protocol stack of the first modem transceiver or may be separately implemented. For example, in the LTE system, the data router may be implemented at a packet data convergence protocol (PDCP) stage or separately at the PDCP stage.

Accordingly, when the first modem processor supports the IMS protocol, the data router transmits IMS data and IMS signaling signals to TCP / IP of the first modem processor, and non-IMS data is transmitted through the TCP / IP of the application processor. Send to connect to the application.

When providing a communication service using a second modem processor that does not support the IMS protocol, the application processor provides the IMS service. For example, when providing a voice call service, the application processor establishes a call via SIP signaling. Thereafter, the application processor processes the audio data provided through the second modem processor to provide a voice call service.

In another example, when providing a video call service, the application processor establishes a call through SIP signaling. Thereafter, the application processor processes the video data and the audio data provided through the second modem processor to provide a video call service.

When handing over from the first modem processor to the second modem processor, the first modem processor transmits information required for the IMS service, such as session information, to the IMS protocol set of the application processor for synchronization and interworking with the IMS protocol set of the application processor. . Accordingly, the application processor may maintain the IMS service using information required for the IMS service provided from the first modem processor.

6 illustrates a data flow for providing an IMS service in the MP of the electronic device according to the second embodiment of the present disclosure.

When providing a voice call service, the first modem processor processes audio data for a voice call service using TCP / IP, an IMS library, and a media engine to provide a voice call service through a PS network.

When providing a video call service, audio data for the video call service is processed in the TCP / IP, IMS library, and media engine of the first modem processor. Video data for the video telephony service is processed in the TCP / IP and IMS libraries of the first modem processor and the media engine of the application processor.

As described above, when video data and audio data for a video call service are processed by different processors, the application processor and the first modem processor exchange information for synchronizing the two data. For example, the first modem processor transmits synchronization information with the audio data together when transmitting the video data to the application processor.

FIG. 7 illustrates a data flow for providing an IMS service in the MP of the electronic device according to the third embodiment of the present disclosure.

When providing a voice call service, the first modem processor processes audio data for a voice call service using TCP / IP, an IMS library, and a media engine to provide a voice call service through a PS network.

When providing a video call service, audio data and video data for the video call service are processed in the TCP / IP and IMS libraries of the first modem processor and the media engine of the application processor.

Accordingly, the data router transmits the IMS data and the IMS signaling signal to the TCP / IP of the first modem processor, and the non-IMS data to be connected to the corresponding application through the TCP / IP of the application.

8 illustrates a data flow for providing an IMS service in an MP of an electronic device according to a fourth embodiment of the present disclosure.

When providing a voice call service, the first modem processor processes audio data for a voice call service using TCP / IP, an IMS library, and a media engine to provide a voice call service through a PS network.

In the case of providing a video call service, audio data and video data for the video call service are processed in an application processor's TCP / IP, IMS library, and media engine.

Accordingly, when switching from the voice call service to the video call service, the application processor provides a video call service by driving a TCP / IP, an IMS library, and a media engine for the video call service.

When switching from video telephony service to voice telephony service, the application processor runs the TCP / IP, IMS library and media engine of the first modem processor. Accordingly, the first modem processor processes voice data using TCP / IP, an IMS library, and a media engine to provide a voice call service.

As described above, when the first modem processor provides the voice call service and the application processor provides the video call service, the data router of the first modem processor transmits the audio signal for the voice call service to the TCP / TCP of the first modem processor. IP data, and data (audio data and video data) for IMS signaling signals and video telephony services are transmitted to TCP / IP of the application processor.

Next, when the IMS protocol set 2 244 illustrated in FIG. 2 is configured as a subset of the IMS protocol set 1, the electronic device uses a modem processor to voice over the PS network as shown in FIG. 9. It can provide call service.

9 illustrates a procedure for providing a voice service in the MP according to the first embodiment of the present invention.

Referring to FIG. 9, in operation 901, the electronic device determines whether a communication service can be provided through a network using an application processor (AP). For example, the electronic device determines whether a communication service can be provided through a Long Term Evolution (LTE) network.

If the communication service can be provided, the electronic device proceeds to step 903 to provide a voice call service through the PS network using a modem processor (MP). For example, when providing a voice call service through the LTE network, the IMS service control unit 224 of the application processor 103 illustrated in FIG. 2 may use the media engine 2 242 and the IMS protocol set of the modem processor 105. 2 (244) and TCP / IP 246 are driven. Subsequently, the modem processor 105 provides a voice call service through the PS network using the media engine 2 242, the IMS protocol set 2 244, and the TCP / IP 246. In this case, the electronic device may reduce power consumption by powering off the application processor.

Thereafter, the electronic device ends this algorithm.

If the electronic device includes a plurality of modem processors, the electronic device may provide an IMS service according to whether the modem processor supports the IMS protocol as shown in FIG. 10 or 11.

10 illustrates a procedure for providing a voice service in an MP according to a second embodiment of the present invention.

Referring to FIG. 10, the electronic device determines a network for providing a communication service using an application processor (AP) in step 1001. For example, if the electronic device includes an LTE modem processor and an enhanced High-Rate Packet Data (eHRPD) modem processor, the electronic device first determines whether the communication service can be provided through the LTE network according to the priority. If the communication service cannot be provided through the LTE network, the electronic device determines whether the communication service can be provided through the eHRPD.

After determining the network for providing the communication service, the electronic device proceeds to step 1003 to determine whether the modem processor of the network for providing the communication service supports the IMS protocol.

If the modem processor of the network for providing the communication service supports the IMS protocol, the electronic device proceeds to step 1005 to check whether the voice call service is provided.

When providing a voice call service, the electronic device proceeds to step 1007 to provide a voice call service through the PS network using a modem processor (MP). For example, when providing a voice call service through the LTE network, the IMS service control unit 224 of the application processor 103 illustrated in FIG. 2 may use the media engine 2 242 and the IMS protocol set of the modem processor 105. 2 (244) and TCP / IP 246 are driven. The modem processor 105 then provides a voice call service using media engine 2 242, IMS protocol set 2 244 and TCP / IP 246. In this case, the electronic device may reduce power consumption by powering off an application processor and a modem processor of a network that does not provide a communication service.

In operation 1005, when providing a service other than a voice call service, the electronic device proceeds to step 1011 to provide an IMS service using an application processor (AP).

If the modem processor of the network for providing the communication service does not support the IMS protocol in step 1003, the electronic device proceeds to step 1011 to provide an IMS service using an application processor (AP). In this case, the electronic device may reduce power consumption by powering off the modem processor of the network that does not provide a communication service.

In addition, when providing a voice call service using a modem processor, the electronic device proceeds to step 1009 to determine whether to switch to a video call service.

In case of switching to the video call service, the electronic device proceeds to step 1011 to provide a video call service using an application processor (AP). For example, when switched to a video call service, the application processor runs a TCP / IP, an IMS library, and a media engine for the video call service to provide the video call service.

On the other hand, if the switch is not switched to the video call service, the electronic device ends the present algorithm. That is, the electronic device provides a voice call service through the PS network using a modem processor.

11 illustrates a procedure for providing a voice service in an MP according to a third embodiment of the present invention.

Referring to FIG. 11, in operation 1101, the electronic device determines a network for providing a communication service using an application processor (AP). For example, if the electronic device includes an LTE modem processor and an eHRPD modem processor, the electronic device first determines whether the communication service can be provided through the LTE network according to the priority. If the communication service cannot be provided through the LTE network, the electronic device determines whether the communication service can be provided through the eHRPD.

After determining the network for providing the communication service, the electronic device proceeds to step 1103 and checks whether the modem processor of the network for providing the communication service supports the IMS protocol.

If the modem processor of the network for providing the communication service supports the IMS protocol, the electronic device proceeds to step 1105 to check whether the voice call service is provided.

When providing a voice call service, the electronic device proceeds to step 1107 to provide a voice call service through the PS network using a modem processor (MP). For example, when providing a voice call service through the LTE network, the IMS service control unit 224 of the application processor 103 illustrated in FIG. 2 may use the media engine 2 242 and the IMS protocol set of the modem processor 105. 2 (244) and TCP / IP 246 are driven. The modem processor 105 then provides a voice call service using media engine 2 242, IMS protocol set 2 244 and TCP / IP 246. In this case, the electronic device may reduce power consumption by powering off an application processor and a modem processor of a network that does not provide a communication service.

In operation 1105, when providing a service other than a voice call service, the electronic device proceeds to operation 1111 to provide an IMS service using an application processor (AP).

If the modem processor of the network for providing the communication service does not support the IMS protocol in step 1103, the electronic device proceeds to step 1111 to provide an IMS service using an application processor (AP). In this case, the electronic device may reduce power consumption by powering off the modem processor of the network that does not provide a communication service.

In addition, when providing a voice call service using a modem processor, the electronic device proceeds to step 1109 to check whether the communication network is changed. For example, the electronic device determines whether to handover from the LTE network to the eHRPD network.

If the communication network is changed, the electronic device proceeds to step 1103 and checks whether the modem processor of the changed communication network supports the IMS protocol.

On the other hand, when the communication network is changed, the electronic device terminates the present algorithm. That is, the electronic device continuously provides a voice call service using a modem processor.

As described above, when a handover occurs between two modem processors, the electronic device may provide a voice call service provided by the modem processor to the application processor. In this case, the IMS protocol set of the modem processor and the IMS protocol set of the application processor should be synchronized and interworked. For example, when connected to an LTE network, the electronic device provides a voice call service using an LTE modem processor. If the electronic device hands over to the eHRPD network, the LTE modem processor transmits information required for a voice call service, such as session information, to the IMS protocol set of the application processor. The application processor may maintain the voice call service through the eHRPD network by using information required for the voice call service provided from the LTE modem processor. At this time, the electronic device may reduce power consumption by deactivating the LTE modem processor except for a section for performing a communication protocol for checking a channel state of the LTE network.

12 illustrates a data flow for providing a voice service in the MP of the electronic device according to the first embodiment of the present disclosure.

As shown in FIG. 12, the modem processor consists of a subset of the IMS protocol of the application processor. For example, the modem processor includes RTP / RTCP of TCP / IP and IMS protocols.

The application processor processes data other than IMS signaling and voice call services. In addition, when providing a voice call service, the application processor establishes a call through SIP signaling and then activates the modem processor's TCP / IP, RTP / RTCP, and media engine.

The modem processor provides voice call service over the PS network using TCP / IP, RTP / RTCP and media engines. In this case, the application processor may be deactivated to reduce power consumption of the electronic device. However, the deactivated application processor is periodically activated for a session refresh procedure that is periodically performed during the voice call service.

When the modem processor provides voice call service through the PS network, the data router transmits data (audio data and video data) for signaling and video call service for call connection to the application's TCP / IP. In addition, the data router transmits an audio signal for voice call service to TCP / IP of the modem processor.

FIG. 13 illustrates a data flow for providing a voice service in the MP of the electronic device according to the second embodiment of the present disclosure.

As shown in FIG. 13, the modem processor consists of a subset of the IMS protocol of the application processor. For example, the modem processor includes sub SIP (light SIP) and RTP / RTCP of the TCP / IP and IMS protocols.

In addition, when providing a voice call service, the application processor establishes a call through SIP signaling and then activates the modem processor's TCP / IP, RTP / RTCP, and media engine. In addition, the application processor transmits information necessary for a session confirmation procedure and the like for the voice call service to the sub SIP of the modem processor.

The modem processor provides voice call service over the PS network using TCP / IP, RTP / RTCP and media engines. In addition, the modem processor performs a session refresh procedure periodically performed during a voice call service using the sub SIP. In this case, the application processor may be deactivated to reduce power consumption of the electronic device.

When the modem processor provides voice call service through the PS network, the data router transmits data (audio data and video data) for signaling and video call service for call connection to the application's TCP / IP. In addition, the data router transmits an audio signal for voice call service to TCP / IP of the modem processor.

As described above, the modem processor performs the session verification procedure using the sub SIP. Accordingly, the data router may include an IMS signaling router as shown in FIG. 14 to distinguish signaling signals related to sub-SIP among IMS signaling signals.

FIG. 14 illustrates a data flow for providing a voice service in an MP of an electronic device according to a third embodiment of the present disclosure.

The IMS signaling router shown in FIG. 14 classifies the IMS signaling signal and transmits the signaling signal related to the session verification procedure processed by the sub SIP to the sub SIP, and routes other signaling signals to the IMS protocol set of the application processor. . In addition, the IMS signaling router handles both the sub-SIP of the modem processor and the IMS signaling transmitted by the IMS protocol set of the application processor.

The sub SIP may be driven only under the condition that the operation of the sub SIP is required, such as a voice call service, under the control of the IMS protocol set of the application processor. Accordingly, the IMS signaling router routes the IMS signaling signal to the sub SIP only when the sub SIP is driven, and routes the IMS signaling signal to the application processor when the sub SIP is not driven.

The application processor deactivated during the voice call service may be activated when the IMS signaling signal is provided from the IMS signaling router.

When providing a voice call service, the modem processor provides a voice call service through the PS network using TCP / IP, RTP / RTCP, and a media engine. For example, the application processor establishes a call via SIP signaling and then activates the modem processor's TCP / IP, RTP / RTCP and media engine. Accordingly, the modem processor provides a voice call service through the PS network using TCP / IP, RTP / RTCP, and a media engine.

When switching from a voice call service to a video call service, the application processor provides a video call service by driving a TCP / IP, an IMS library, and a media engine for the video call service.

The data router of the modem processor transmits audio signals for voice call service to TCP / IP of the modem processor, and transmits signaling signals and data (audio data and video data) for video call service to the TCP / IP of the application. If the voice call service is switched to the video call service, the data router may switch the voice data path from the modem processor's TCP / IP to the application processor when the TCP / IP of the application processor, the IMS library, and the media engine are driven for the video call service. Switch to TCP / IP

In other words, when switching from a voice call service to a video call service, the data router transmits to the modem processor TCP / IP without switching the voice data path. Meanwhile, the data router transmits IMS signaling and video data to the application processor's TCP / IP for processing.

As described above, when video data and audio data for a video call service are processed by different processors, the application processor and the modem processor exchange information for synchronizing the two data.
