Evolved hybrid internet protocol (IP) multimedia subsystem (IMS) architecture

摘要

A method, apparatus, and computer program product for wireless communication are provided. The method generally includes registering a UE with an internet protocol multimedia subsystem (IMS) server for one or more native services and non-native services, wherein the UE comprises a modem processor and an application processor. The IMS server may comprise an RTP stack, wherein a portion of the RTP stack resides on the MP and a portion on the AP. A data packet may be received having an identifier of one of the native or non-native services. The data packet may be received from a WWAN or IWLAN. The data packet may be forwarded to the MP or to the AP based on the identifier. According to aspects, the data packet is forwarded to the MP if the identifier indicates an audio service and to the AP if the data packet indicates a video service.

主权项

1. A method of wireless communication, comprising:
registering a user equipment (UE) with an internet protocol (IP) multimedia subsystem (IMS) server for one or more native services and for one or more non-native services, wherein the UE comprises a modem processor and an application processor, wherein the registering comprises a registration to obtain an internet protocol (IP) address shared by the modem processor and the application processor for both the one or more native services and the one or more non-native services; receiving, at the UE, a data packet having an identifier of one of the one or more native services or one of the one or more non-native services; forwarding the data packet to the modem processor or to the application processor based on the identifier, wherein forwarding the data packet to the modem processor or to the application processor based on the identifier comprises forwarding the data packet to the modem processor if the identifier indicates an audio service and forwarding the data packet to the application processor if the data packet indicates a video service; and synching data packets indicating audio service and data packets indicating video service, wherein the synching comprises using a delay coefficient to account for delays of forwarding the data packet of the application processor.
