Abstract
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.
