Abstract
Methods and systems for restricting communication services over a network. The method includes detecting a Session Initiation Protocol (SIP) register message originating from a specific network Public Land Mobile Network (PLMN) that is included in a restricted PLMN list identified by a P-Access-Network-Information header (P-ANI). The method further includes implementing a policy to remove RCS and presence capability feature tags from a subsequent SIP register message. The lack of feature tags to Serving Call Session Control Function (S-CSCF) will prohibit triggering of Third Party Registration to different application servers.
