Abstract
Various embodiments comprise a wireless communication network to inhibit multimedia session drop. In some examples, the wireless communication network comprises Call Session Control Function (CSCF) circuitry. The CSCF circuitry receives a multimedia registration request from a user device that comprises a registration timer indication. The CSCF circuitry registers the user device for multimedia services and sets a registration timer based on the registration timer indication. The CSCF circuitry receives a multimedia session request from the user device and establishes a multimedia session based on the session request. The CSCF circuitry determines when the registration timer expires and when the multimedia session is active. When the registration timer expires and the multimedia session is active, the CSCF circuitry maintains the registration of the user device. When the registration timer expires and the multimedia session is inactive, the CSCF circuitry deregisters the user device.
