摘要： A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload offload mobile traffic it provides a platform for new communication services. The proxy switch includes signaling message handling logic that receives signaling messages from the MSC and BS in accordance with a mobile signaling protocol. State logic maintains state information of call sessions and mobile stations (MSs) used within the mobile communications network. Message interception logic detects whether a signaling message from an MSC is a new call originating message and if an MS addressed in such a new call originating message is involved in a call. The message interception logic also prevents the new call originating message from being forwarded to the BS servicing the addressed MS. Message conversion logic converts the new call originating message to a feature notification message, and message transmission logic issues the feature notification message to the BS servicing the addressed MS.

摘要： A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload mobile traffic it provides a platform for new communication services. A proxy switch includes signaling message handling logic for sending and receiving signaling messages to and from the MSC on a first signaling link and sending and receiving messages to and from the BS on a second signaling link; wherein the second link has a mapped correspondence to the first link. Message interception logic detects whether a signaling message from an MSC is a COO, indicating that the MSC will not receive signaling messages on the first signaling link. The message interception logic also prevents the COO from being forwarded to the BS and generates and sends a change over acknowledge (COA) message to the MSC. Signaling message redirection logic receives signaling messages on the second signaling link and provides control information contained therein to the alternative communication network after the message interception logic detects the COO; and bearer circuit redirection logic receives information from a bearer circuit corresponding to the second signaling link and directs the information to the alternative communication network.

摘要： A proxy switch, communication method for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. A BS is in trunk line communication with the switch and the trunk line communication is organized as bearer circuits, each bearer circuit identifiable with a circuit identification code (CIC). The switch receives signaling messages from the the BS and determines if a call corresponding to the signaling message is to be handled by the alternative communication network. If so, the switch assigns a CIC for a bearer circuit for the call and communicates the CIC to the BS. Thereafter, the switch receives information on the CIC-identified bearer circuit and forwards the received information to the alternative network.

摘要： A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload offload mobile traffic it provides a platform for new communication services. A proxy switch includes signaling message handling logic for receiving signaling messages from the MSC and BS in accordance with said mobile signaling protocol. Message transmission logic issues messages to the MSC and BS. A FSN and a BSN are provided for communication with the MSC, and another FSN/BSN pair are provided for communication with the BS. Logic detects whether a received message is a change over order message (COO) from one of the MSC and BS, indicating a break in a first signaling link between the proxy switch and the one of the MSC and BS, and logic generates and sends a COA message to the one of the MSC and BS containing the BSN maintained by the switch for communication with the one of the MSC and BS. Fault emulation logic forces a break in a second signaling link between the proxy switch and the other of the MSC and BS, wherein the second signaling link is configured to correspond to the first signaling link, and generates and sends a new COO message to the other of the MSC and BS.

摘要： A method and system of determining a GGSN to serve data calls in a mobile communications network is provided. Messages are received from a SGSN (310), and analyzed to determine if the message is requesting the identity of a GGSN (315). If the received message is requesting the identity of a GGSN (315), a GGSN selection algorithm is executed to identify a GGSN to serve data calls from a specified MS (325). A reply is then constructed and sent to the SGSN identifying the selected GGSN (330).
