Various embodiments comprise wireless communication network to register user devices with multimedia systems. In some examples, the wireless communication network comprises multimedia functions and a subscriber server. A first multimedia function receives a registration request for a wireless user device, selects the subscriber server from a plurality of available subscriber servers, and transfers a user authorization request for the user device to the subscriber server. The subscriber server receives the user authorization request and transfers a response indicating a server Identifier (ID) for the subscriber server. The first multimedia function receives the response and indicates the server ID and the registration request to a second multimedia function. The second multimedia function receives the server ID and the registration request, selects the same subscriber server based on the server ID, and transfers a multimedia authorization request to the subscriber server.

Internet protocol multimedia subsystem (IMS) registration in wireless communication networks

Various embodiments comprise a wireless communication network to maintain multimedia sessions in response to bearer failure. In some examples, the wireless communication network comprises Call Session Control Function (CSCF) circuitry. The CSCF circuitry requests a dedicated bearer to serve a requested multimedia session in response to a multimedia session request for a user device received over a default bearer. The CSCF circuitry receives an error message that comprises an error code indicating the dedicated bearer could not be established. The CSCF circuitry determines when the default bearer can support the requested multimedia session based on the error code. The CSCF circuitry maintains the default bearer for the user device and establishes the requested multimedia session over the default bearer when the default bearer can support the requested multimedia session.
