Abstract:
1. A method of operating a user equipment (UE) within a wireless communications system, comprising: determining that a current serving network of the UE is associated with a network support zone of a given type, wherein network support zones of different types are characterized by different levels of support for a multimedia client application configured to manage server-arbitrated communication sessions at the UE, wherein the different types of network support zones include two or more types that permit the multimedia client application to actively engage in the server-arbitrated communication sessions at different levels of support; loading, based on the determination, a set of zone-specific network procedures and/or features for supporting the multimedia client application within the network support zone of the given type; and executing the set of zone-specific network procedures and/or using the set of zone-specific network features at the UE while connected to the current serving network, wherein the determining step identifies the given type of the current serving network as corresponding to a first type being a home and/or affiliate network of the UE configured to provide a full level or high level of support for the multimedia client application, a second type being a roaming network of the UE configured to provide an intermediate level of support for the multimedia client application or a third type being a roaming network of the UE configured to provide zero-support or low support for the multimedia client application, wherein the first, second and third types are associated with different zone-specific network procedures and/or features and the UE is provisioned with the zone-specific network procedures and/or features at least for the given type, and wherein the loading step loads the provisioned zone-specific network procedures and/or features for the given type as the set of zone-specific network procedures and/or features.
