Abstract
Abstract A distributed SS7 call terminating processor (102) for processing calls received over an SS7 network (105) includes a set of N simultaneously active digital channel interfaces (DCIs) (121) sharing a common signaling point code. The set of DCIs (121) receives common channel signaling messages. Each of the N simultaneously active DCIs (258) includes an SS7 message transfer part level one (MTPL1) physical layer (259) coupled on a one to one basis to a common channel signaling link (110), an SS7 message transfer part level two (MTPL2) link layer (256) and an SS7 message transfer part level three (MTPL3) network layer (253) having the common signaling point code. An operation and maintenance controller (108) includes a configuration function (315) that configures each SS7 MTPL3 network layer (253) in the set of N simultaneously active DCIs (121) to have the common signaling point code.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A distributed signaling system seven (SS7) call terminating processor for processing calls received over an SS7 network, comprising: a set of N simultaneously active digital channel interfaces (DCIs) sharing a common signaling point code, wherein said set of N simultaneously active digital channel interfaces receives common channel signaling messages, and wherein N is a positive integer greater than 1, and wherein each of said N simultaneously active DCIs comprises an SS7 message transfer part level one (MTPL1) physical layer coupled on a one to one basis to a common channel signaling link; an SS7 message transfer part level two (MTPL2) link layer, coupled to said SS7 MTPL1 physical layer; an SS7 message transfer part level three (MTPL3) network layer having the common signaling point code and coupled to said SS7 MTPL2 link layer; and an operation and maintenance controller (OMC) which comprises a configuration function that configures each SS7 MTPL3 network layer in said set of N simultaneously active DCIs to have the common signaling point code.
Claim 2
Dependent Claim
167 words
A distributed signaling system seven (SS7) call terminating processor for processing calls received over an SS7 network, comprising: a set of N simultaneously active digital channel interfaces (DCIs) sharing a common signaling point code, wherein said set of N simultaneously active digital channel interfaces receives common channel signaling messages, and wherein N is a positive integer greater than 1, and wherein each of said N simultaneously active DCIs comprises an SS7 message transfer part level one (MTPL1) physical layer coupled on a one to one basis to a common channel signaling link; an SS7 message transfer part level two (MTPL2) link layer, coupled to said SS7 MTPL1 physical layer; an SS7 message transfer part level three (MTPL3) network layer having the common signaling point code and coupled to said SS7 MTPL2 link layer; and an operation and maintenance controller (OMC) which comprises a configuration function that configures each SS7 MTPL3 network layer in said set of N simultaneously active DCIs to have the common signaling point code.
Claim 3
Dependent Claim
60 words
The distributed SS7 call terminating processor according to claim 1, wherein each of said N simultaneously active DCIs further comprises an SS7 monitor function which generates a periodic heartbeat message, and wherein the OMC further comprises an alarm function which responds to a lack of reception of a heartbeat message from one of said set of N simultaneously active DCIs.
Claim 4
Dependent Claim
18 words
The distributed SS7 call terminating processor according to claim 2, wherein the response is an operator sensible alert.
Claim 5
Dependent Claim
31 words
The distributed SS7 call terminating processor according to claim 2, wherein the response is a reconfiguration of an inactive DCI to be active and to have the common signaling point code.
Claim 6
Dependent Claim
48 words
The distributed SS7 call terminating processor according to claim 1, wherein the OMC further comprises an alarm function which responds to an SS7 network management message received from a remote signal transfer point by reconfiguring an inactive DCI to be active and have the common signaling point code.
