摘要:
A method is provided for identifying a device during an emergency for callback. The method includes storing an address of a user agent (UA) during initiation of an emergency call by the UA, associating an E.164 number with the stored address of the UA that placed the emergency call, and routing the emergency call containing the E.164 number.

A method for a user agent to access a session policy in a network is provided. The method comprises sending, from the user agent, a single session policy request to a single network component, the single network component contacting a plurality of network components, wherein sending the single session policy request to the single network component utilizes a lower layer protocol. The lower layer protocol is at least one of Extensible Authentication Protocol (EAP), Point to Point Protocol (PPP), and General Packet Radio Service (GPRS) Activate Packet Data Protocol (PDP) context. The method further comprises aggregating policy information and providing the aggregated policy information to the user agent.
摘要:
A method for providing a user agent (UA) with service identification data. The method includes an application server (AS) transmitting Session Initiation Protocol (SIP) data. The SIP data comprises an identifier of the AS and a service identifier for at least one service supported by the AS. The method further includes the UA receiving the SIP data.
摘要:
In one embodiment, an IMS network node is operable, responsive to receiving a SIP INVITE 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 SIP INVITE message back to the enterprise user. The IMS network node includes functionality for establishing a second call leg to the called party. The first and second call legs are patched to establish an end-to-end communications path between the enterprise user and the called party, wherein an enterprise address instead of a non-enterprise address of the enterprise user is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.
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:
A method of call routing is provided. The method comprises receiving a session initiation protocol (SIP) INVITE message that contains a uniform resource identifier (URI) of a called party and that identifies that a bearer for a call to the called party is to be set-up at least in part over the circuit switching domain. The method also comprises determining a digit string associated with the URI. The method also comprises sending a SIP informational response message having a contact header that contains information based on the digit string.
摘要:
A network component is provided that includes a processor configured, upon the network component receiving an IMS (Internet Protocol Multimedia Subsystem) emergency call from a user equipment (UE) 110, to detect in the emergency call an indicator requesting the network component to restrict presentation of private information related to the UE 110. The processor is further configured, when the indicator is present, to transmit the emergency call without at least some of the private information to a Public Safety Answering Point (PSAP) 130.
摘要:
According to one aspect, a system and method of exchanging GRUUs (Globally Routed User Agent URI (Uniform Resource Identifier)) between a first telephony-enabled device and a second telephony enabled device using a circuit-switched message is provided. Once exchanged, the telephony enabled devices can exchange SIP (session initiated protocol) communications routed by the GRUUs. Any one of the telephony-enabled devices can add a media component to the SIP communications. According to another aspect, a system and method of generating GRUUs is provided. According to another aspect, a system and method of handing off communications to a packet switched network from a circuit switched network is provided.
