  • This proposed application ID may have been part of an HTML page downloaded by the UE, and would be provided by the UE in the SDP offer when establishing an application DC.
  • TR 23.700-87 it was not determined as to how the UE would be aware of the application ID, as this was not specified in the proposal.
  • a number of other problems were identified with this proposal, as follows.
  • both an originating and a terminating DCS may provide an IMS DC service.
  • An application may be downloaded from either the originating or terminating DCS.
  • An IMS application server (AS) may then send a message to the DCS based on subscription data.
  • the subscription is not based on the application itself. Therefore, the IMS AS does not know which DCS is serving the application and cannot ‘skip’ other DCS that are not serving the application.
  • the IMS AS invokes a ‘wrong’ DCS (i.e.
  • the DCS might wrongly process the application DC request when a stream ID and a DC application ID are duplicated. It may be possible for the stream ID and the DC application ID to be duplicated on both the originating and the terminating network. This is because there is no mechanism to sync-up the assignments among network operators.
  • the application type e.g. person to person (P2P) , person to application (P2A) , application to person (A2P)
  • DCS application logic handling each application may be different for different application types. For example, for P2P type applications, the DCS does not need to reserve DC media resources for this application. In other example, for P2A type applications, the DCS will establish the application DC between the UE and the DCS/network application server.
  • the application lifecycle management on the UE may not be efficient. This is because the UE downloads the application from the DCS, which causes latency delays and uses bandwidth.
