Abstract: Communications methods and apparatus for preserving STIR/SHAKEN original attestation/signature information for diverted Session Initiation Protocol (SIP) messages and/or calls.

Abstract: Communications methods and apparatus for providing and/or adding STIR/SHAKEN Diversion Information to requests. An exemplary method embodiment includes the steps of: receiving at a second communications network a Session Initiation Protocol (SIP) Invite request from a first communications network, the SIP Invite request being directed to a first SIP address corresponding to a first user equipment device located within the second communications network, the SIP Invite request including a SIP Identity shaken header and one or more SIP Identity div headers; determining at the second communications network whether or not the received SIP Invite request was previously diverted by the second communications network to another network; and when the SIP Invite request is determined to have been previously diverted by the second communications network to another network, processing the SIP Invite request at the second communications network as a previously received and diverted SIP Invite request.

Abstract: Systems, methods, and computer-readable storage media are disclosed which provide improved performance for packet switched (PS)-to-PS handovers. Embodiments provide for improved handover operations by utilizing registration refreshing techniques to reduce the time required to complete signaling and registration of a UE over a target access in connection with a handover of a communication session from a serving access to the target access. Embodiments further provide improved handover operations that eliminate the exchange of signaling information with a remote UE in connection with a handover of a communication session from a serving access to the target access. Further, handover operations are processed by a network node that is closer to the UE requesting the handover (e.g., the network node may be an Access-SBC/P-CSCF that operates between a core network and the UE).
