Title:

DATA CHANNEL COMMUNICATIONS ASSOCIATED WITH AN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/031419

Kind Code:

A1

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may obtain a data channel establishment request comprising session description protocol (SDP) information corresponding to a multimedia call session between a first user equipment (UE) and a second UE, the SDP information including a data channel application identifier corresponding to a data channel application. The first network node may provide, to a second network node, a data channel service request that indicates the data channel application identifier. The first network node may obtain, from the second network node, a service response comprising a data channel control policy associated with the data channel application identifier and may allocate, based at least in part on the data channel control policy, media resources corresponding to at least one application data channel. Numerous other aspects are described.
