The invention expedites the delivery of a call originating in a circuit-switched network to a mobile terminal camped on a packet-switched network. Information representing the location of the mobile terminal in the packet-switched network is provided to the circuit switched network. A call setup with the mobile terminal is initiated with reference to the previously received location information, frequently more expeditiously and using less resources. Location-based services are also provided by the circuit-switched network with access to such mobile terminal location information.

A system for delivering a call to a mobile unit in a wireless network includes a mobile switching center that receives a call setup request message initiated in response to a request from an originating mobile switching center. The receiving mobile switching center initiates setting up the call between the receiving mobile switching center and the mobile unit before the call is setup between the receiving mobile switching center and the originating mobile switching center. Preferably, the receiving mobile switching center initiates setting up the call by issuing a page in response to receiving the call setup message.

An improved system and method is disclosed for call handling in a packet network such as a CDMA, UMTS, GSM, and other networks similarly configured. The system may include an anchor media gateway that remains in a communication path even if the call has been handed off to another media gateway. The anchor media gateway includes first and second ports for establishing first and second links to transfer packet communications to and from the first and second entities, respectively. First and second packet connections are provided for interconnecting the first and second links, respectively, to an audio server. A third link connected to the audio server and is provided for transferring packet communications to and from the third entity. The audio server manipulates the packet communications received from the first, second, and third entities and provides the manipulated packet communications to the first, second, and third entities. The manipulation performed by the audio server can be combining the packet communications to provide an n-way call (e. g.

A message protocol on a communication network between an originating and terminating communication device transmits the cost and quality of service impact of selecting a CODEC standard where no single CODEC is supported in the end-to-end packet transmission. Each call agent server on the communication generates and submits a session initiation protocol (SIP) message containing a data element for the additional cost and a data element for the additional total quality of service degradation, calculating the additions considering all prior calculated data elements. The data elements are part of the session description protocol message. Either the final server prior to the terminating communication device or the terminating communication device operates an algorithm to make an optimal selection and avoid unnecessary high cost or degraded quality of service. The selected CODEC standard is communicated back to the servers in an SIP response message.

A system and a method in a wireless network utilizing session initiation protocol (SIP) for call control. The SIP payload (SDP) contains a list of voice codecs to coordinate the selection of voice bearer resources (between a calling party and a called party) such that the number of transcoders in the voice bearer path is minimized. An additional aspect of the embodiment of the present invention includes a serving MSCe that is operable to determine whether to initiate or discontinue ringback to the calling party. If ring back is to be initiated, ringback can be initiated from a Serving MGW controlled by the serving MSCe. The call negotiation process according to the described embodiment of the invention eliminates the requirement for any transcoding in specific situations to result in the number of transcoders used in the voice bearer path to be reduced to 0 (TrFO, Transcoder Free Operation) or to 1 (RTO, remote transmitter operation).

Call setup in a wireless communication network that includes a circuit fabric and a packet fabric. The originating MSCe receives an origination message including a call termination identifier, and a predictive bearer path matching mode is determined. When the originating MSCe is in a first predictive bearer path matching mode, the originating MSC generates a bearer resource preference list based upon the termination identifier. The bearer resource preference list includes a predetermined priority order of a plurality of bearer path resource identifiers including at least one of a packet bearer resource identifier and a circuit bearer resource identifier. When the originating MSCe is in a second predictive bearer path matching mode, the MSCe generates a bearer resource preference list to indicate whether the originating MSCe couples to a packet bearer resource or a trunk bearer resource. The originating MSCe sends, in response to the origination message, the bearer resource preference list to an originating base station controller (BSC). The originating BSC matches an available bearer path resource of the originating BSC based upon the bearer resource preference list.
