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

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.
