Abstract: Methods, systems, and computer program products for providing telecommunication services between a SIP network and an SS7 network are disclosed. In one method, SIP/SS7 gateway receives an INVITE message from a SIP proxy server. The SIP/SS7 gateway extracts a called party number from the INVITE message and determines whether a telecommunications service is required and a type of service required for the INVITE message based on the called party number. The SIP/SS7 gateway then formulates an SS7 query to a database corresponding to the identified service type. The SIP/SS7 gateway receives a response from the database and uses data from the response to facilitate completion of the call. In one example, the SIP/SS7 gateway may forward a routing number extracted from the response back to the originating SIP proxy server. In another example, the SIP/SS7 gateway may generate a new INVITE message and forward the new INVITE message to a terminating SIP proxy server.

Abstract: A transport adapter layer interface (TALI) includes messages, processes, and packet structures for sending and receiving SS7 information over a stream-oriented connection, such as a TCP/IP connection. For example, the TALI interface includes test messages for testing the status of a connection and allow and prohibit messages for enabling and disabling service data communications without invoking a TCP handshaking procedure. The TALI interface also includes SYNC and LENGTH fields for facilitating extraction of individual message packets over a stream-oriented connection.

Abstract: A scalable call processing node includes link interface modules capable of processing n calls per second and call server modules capable of processing m calls per second, n is variable relative to m by changing the relative numbers of call server and link interface modules. In addition, call server modules can perform subsecond switchover when a call server fails without requiring inter-call server transfer of call state information.

Abstract: Methods and systems for performing sales transactions using a mobile communications device and without requiring text messaging or paging services are disclosed. In one example, a subscriber desiring to purchase goods or services proceeds to a point of sale device where the purchase price for the goods or services is totaled. The subscriber then initiates a voice call with a central transaction server. The subscriber provides a point of sale device identifier and the purchase price to the central transaction server. The central transaction server contacts a local transaction server using the identifier provided by the subscriber. The central transaction server also prompts the subscriber to select the payment account for the transaction and verifies that the subscriber has sufficient credit to purchase the goods or services. The central transaction server locates a pending transaction entry in a database local to the point of sale using the device identifier provided by the subscriber.

Abstract: Disclosed is a communications network element that is capable of routing signaling messages and includes a dynamic routing key registration feature which allows Internet protocol (IP) nodes to automatically register/de-register and subsequently direct traffic towards or away from themselves without the need for manual operator intervention. A signaling gateway routing node includes a self-registering data communication module (sDCM) that is adapted to receive and process dynamic routing key registration messages from associated IP nodes. Such dynamic routing key registration messages may include information that is used to register a new routing key association with a TCP/IP connection, de-register an existing routing key association with the TCP/IP connection, or modify routing key information associated with the TCP/IP connection.

Abstract: Methods and systems for routing messages between a core network and a radio network controller are provided. A radio access network gateway translates messages from an ATM-based protocol to a non-ATM-based protocol, such as the stream control transmission protocol and vice versa. The radio access network gateway forwards the SCTP messages to the core network. In addition, the radio access network gateway receives messages from the core network formatted according to the core network protocol and translates these messages to an ATM-based protocol for communication to a radio network controller.

Abstract: Methods and systems for providing SIP trunk groups are disclosed. A SIP call processor identifies an incoming SIP trunk group based on one or more parameters associated with an incoming SIP message. The SIP call processor selects per-trunk-group call processing data based on the incoming SIP trunk group. The SIP call processor selectively processes the call based on the per-trunk-group call processing data selected for the incoming SIP trunk group.

Abstract: A network element provides service control point or database node front end processing functionality, as well as routing functionality for routing data packets through a network. The network element includes a first communication module for receiving data packets from a first communication network. A second communication module transmits data packets over a second communications network. A database access control (DAC) process queries a DAC database and modifies received packets to include information returned by the database lookup.
