A method in a user agent (UA) is provided. The method includes sending a SIP REGISTER request, and receiving a SIP REGISTER response message. The SIP REGISTER response message has a first header field that includes an identifier associated with a trusted network node. The method also includes receiving a SIP message having a second header field for indicating a URI, and sending a SIP communication if the URI matches the identifier associated with the trusted network node.

A method on a wireless user equipment (UE) device facilitates integration of an outgoing cellular call as an enterprise call. The UE device attaches to a wide area cellular network on which the device has a non-enterprise address. Upon blocking incoming calls, the UE device sends a request to a node in a data network to initiate an outgoing cellular call with an expectation of receiving an incoming circuit-switched (CS) call back from the network node within a time window. The incoming CS call contains an enterprise address associated with a user of the wireless UE device as a calling line identity to identify that the incoming CS call is related to the request to initiate the outgoing cellular call. The UE device indicates to the network node that a call leg is established between the enterprise user and the network node.

A method for modifying the contents of session initiation protocol (SIP) messages is presented. The method includes receiving a SIP message. The SIP message may include a set of message header fields. The method includes receiving an application policy. The application policy may specify how to modify the SIP message based on a characteristic of the SIP message. Alternatively, the application policy may be retrieved from a database such as one provided by a home subscriber server (HSS) or an application server. The method includes using the application policy to modify the SIP message resulting in a modified message, and sending the modified message.
摘要:
In one embodiment, a scheme is disclosed for routing an incoming call in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network, wherein the incoming call is being directed to a user equipment (UE) device disposed in the network environment. A network node disposed in the IMS network is operable to perform a number of determinations with respect to the UE device's domain, state, applicability of user and/or operator policies and preferences, location, et cetera. The incoming call is terminated to an appropriate domain (e.g., CS domain or IMS domain) based at least in part upon the foregoing determinations.
摘要:
An apparatus, and an associated method, for directing communications of a communication session to a selected communication device, or devices, of a group of commonly-registered devices. A device-direction policy is created and stored at a network entity. The policy identifies preferred devices to which communications of a communication session are to be provided. A SIP Invite, or other communication-session initiation message, is provided to the network entity. The network entity detects the message, accesses the policy, and forwards on the message in accordance with the policy.
摘要:
In one embodiment, a network node is operable, responsive to receiving a request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a circuit-switched call that identifies an enterprise address of the enterprise user as a calling line identity. The network node includes functionality for establishing a second call leg to the called party upon receiving an indication from the enterprise user that the first call leg has been established. The first and second call legs are then patched to establish an end-to-end communications path between the enterprise user and the called party, wherein the enterprise address instead of the non-enterprise address is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.
摘要:
Apparatus, and an associated method, for generating and transmitting an anonymous GRUU, or other routing identifier, to identify a user agent in a communication system that utilizes SIP signaling. A user agent-generated message is generated that identifies a user agent-request for anonymous operation. And, a SIP registrar, or other network device, operates to provide an anonymous routing identifier that permits anonymous operation of the user agent to maintain privacy of its identity during communications.
摘要:
A network selection scheme operable in a network environment having one or more radio access networks (RANs), one or more core networks (CNs), and one or more service networks (SNs). Upon obtaining identity information of a particular network combination, a wireless user equipment (UE) device is operable to register with a roaming broker (RB), whereby additional information may be provided to the device for facilitating appropriate network selection.
摘要:
In one embodiment, a scheme is disclosed for managing call continuity in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network wherein a SIP Invite message having a Domain Transfer-URI contained in the Request-URI that is operable to trigger a return of a routable number is utilized. Responsive to the SIP Invite message from a UE device, a network node provides a SIP response message (e.g., SIP 380 (Alternative Service) Response) which includes one or more radio access technologies and an alternative domain available to the UE device for continuing a call from one domain to another domain.
摘要:
A network component is provided. The network component including a component configured such that the network transmits a response message containing an indicator indicating that a first message is an emergency-related request, and such that the network receives a second message containing information associated with a user equipment (UE).
