摘要： Methods, systems, and computer program products for using an LRN based query and response mechanism (e.g., a switching office number portability processing system) to route calls to IP multimedia subsystem (IMS) subscribers are disclosed. According to one method, an LRN based response message including a communications service subscriber identifier is received. An IMS gateway LRN associated with the communications service subscriber identifier may be determined. The IMS gateway LRN associated with the communications service subscriber identifier may be inserted into the LRN based response message and routing the message.

摘要： Methods and systems for intelligent signaling-router-based surveillance are disclosed. A surveillance and signaling router receives call signaling messages, identifies call signaling messages associated with users under surveillance and determines a surveillance type for the call signaling messages. If the surveillance type is content-related, the surveillance and signaling router forwards the message to a call server. The call server replaces parameters in the message and in subsequent messages so that the call is transparently set up through a media proxy server. The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.

摘要： A method for providing presence gateway functionality includes deriving presence information for subscribers in a first set of subscribers based on telecommunications signaling messages. The first set of subscribers includes at least one subscriber who is not a subscribed-to presentity. The method also includes determining whether presence status information for a subscriber in the first set of subscribers has changed. In response to detecting a change in presence status, it is determined whether the subscriber is a subscribed-to presentity. If the subscriber is a subscribed-to presentity, a presence server is notified of the change in status of the subscriber.

摘要： 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.

摘要： Seamless transport of messages is provided between SS7 network elements and Internet Protocol (IP) network elements using an STP as an intermediary. Thus, messages may be routed between a first SP and a second SP via an STP using IP. Messages may be routed between an SP and an IP node via an STP using IP. Messages also may be routed between a first IP node and a second IP node via an STP using IP. Thus, the STP can be used as a vehicle for message transport among nodes of an SS7 network, among nodes of an IP network and between SS7 and IP networks. SS7 messages are bidirectionally communicated between an STP and at least one other SP of an SS7 network using IP, preferably TCP/IP. Preferably, SS7 messages are bidirectionally communicated between an STP and at least one SCP using IP. In particular, a first SS7 message that is received from the STP includes an SS7 Message Transfer Part (MTP) layer, an SS7 Signaling Connection Control Part (SCCP) layer and an SS7 Transaction Capability Application Part (TCAP) layer. The MTP layer (SS7 levels 1-3) is stripped from the first SS7 message. An IP routing layer is added to the SSCP layer and the TCAP layer that remain in the first SS7 message, to create a first IP message. The IP routing layer includes an IP address. The first IP message is transmitted to the IP address over an IP network. A second IP message is received from the IP network. The second IP message includes an SS7 SCCP layer, an SS7 TCAP layer and an IP routing layer. The IP routing layer is stripped from the second IP message to create a second SS7 message including an SS7 SCCP layer and an SS7 TCAP layer. The second SS7 message is then transferred to the STP.
摘要翻译：使用STP作为中介，在SS7网元和互联网协议（IP）网元之间提供消息的无缝传输。因此，消息可以经由使用IP的STP在第一SP和第二SP之间路由。消息可以通过使用IP的STP在SP和IP节点之间路由。消息还可以经由使用IP的STP在第一IP节点和第二IP节点之间路由。因此，STP可以用作SS7网络的节点之间，IP网络的节点之间以及SS7和IP网络之间的消息传输的载体。 SS7消息在STP和SS7网络的至少一个其他SP之间使用IP，优选地TCP / IP双向传送。优选地，使用IP在SSP和至少一个SCP之间双向地传送SS7消息。特别地，从STP接收的第一SS7消息包括SS7消息传送部分（MTP）层，SS7信令连接控制部分（SCCP）层和SS7事务能力应用部分（TCAP）层。从第一个SS7消息中剥离MTP层（SS7级别1-3）。将IP路由层添加到保留在第一SS7消息中的SSCP层和TCAP层，以创建第一IP消息。 IP路由层包括一个IP地址。第一个IP消息通过IP网络传输到IP地址。从IP网络接收到第二个IP消息。第二个IP消息包括SS7 SCCP层，SS7 TCAP层和IP路由层。从第二IP消息剥离IP路由层以创建包括SS7SCCP层和SS7 TCAP层的第二SS7消息。然后将第二个SS7消息传送到STP。

摘要： Methods, systems, and computer readable media for inducing the activation of a service trigger at a switching office in a communications network are disclosed. According to one method, a call setup message associated with a call is received. It is then determined whether service trigger induction is required for the call. In response to determining that service trigger induction is required for the call, the call setup message is modified to include service trigger induction information and the modified call setup message is directed to a destination switching office. At the destination switching office, a service trigger is activated based on the service trigger induction information in the modified call setup message.

摘要： Methods, systems, and computer readable media for early media connection proxying are disclosed. According to one method, a call setup signaling message is received for establishing a call between a calling entity and a called entity. Based on at least one parameter in the call setup signaling message, it is determined whether an early media connection is required for the call. It is also determined whether early media connection proxying is required for the call. In response to determining that an early media connection and early media connection proxying are required for the call, signaling is performed on behalf of a network entity to establish an early media connection for the call.
