Abstract
Abstract Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network. The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network. SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor. The call processor communicates with one or more switching processor means for controlling establishment of the call. Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection. Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
130 words
Apparatus for controlling establishment of call connections in a telecommunications network, comprising; a plurality of SPPs (switching processing platforms); a plurality of switches, each comprising a switching fabric, and switching processor means responsive to receipt of connection request messages for establishing a call connection in said switching fabric; data network means interconnecting said plurality of SPPs with the switching processor means; said plurality of SPPs comprising a plurality of CPs (call processors) spread over at least two SPPs; said plurality of SPPs comprising means for receiving signaling messages for a call and transmitting said received signaling messages for said call to one of said CPs; said one of said CPs for generating said connection request messages for transmission to ones of said switching processor means for establishing said call connection.
Claim 2
Dependent Claim
24 words
The apparatus of claim 1 wherein said plurality of SPPs comprises a plurality of signaling link processors for receiving signaling messages for a call.
Claim 3
Dependent Claim
26 words
The apparatus of claim 2 wherein said plurality of SPPs comprises a plurality of administrative processors for controlling operations administration and maintenance of said telecommunications network.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 wherein said plurality of SPPs comprises at least one SP/NCP (service processor/network control point) for providing data for control of specialized telecommunications calls.
Claim 5
Dependent Claim
20 words
The apparatus of claim 1 wherein said plurality of switches comprise a plurality of PCM (pulse code modulation) digital switches.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 wherein said plurality of switches comprises a plurality of ATM (asynchronous transfer mode) switches.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1 wherein said data network means comprises an ATM (asynchronous transfer mode) network.
Claim 8
Dependent Claim
37 words
The apparatus of claim 7 wherein said data network comprises a plurality of ATM/LANs (ATM local area networks) each for interconnecting the processors of one of said SPPs and for connection to an inter SPP data network.
Claim 9
Dependent Claim
25 words
The apparatus of claim 1 wherein said CP determines an identity of an outgoing trunk group for connection of said call to a terminating network.
Claim 10
Dependent Claim
20 words
The apparatus of claim 9 wherein said switching processors means control the selection and establishment of connections within said network.
Claim 11
Dependent Claim
37 words
The apparatus of claim 1 wherein a call on a trunk can be assigned to one of a plurality of CPs, said plurality of CPs comprising at least one CP in each of at least two SPPs.
Claim 12
Dependent Claim
132 words
In a telecommunications network, a method of extending a call toward a destination comprising the steps of: receiving call setup request messages for a call in a SLP (signaling link processor) of said network, said messages comprising an identity of an incoming line or trunk; assigning one of a plurality of CPs (call processors) for controlling extension of said call in said telecommunications network; transmitting said call setup request messages from the receiving SLP to said assigned CP; transmitting an identity of the assigned CP to switch processor means for controlling a switching network fabric of a switch serving the incoming line or trunk; and transmitting connection request messages from said assigned CP to said switch for extending said call from an incoming line or trunk of said call toward said destination.
Claim 13
Dependent Claim
46 words
The method of claim 12 wherein said connection request messages comprise an identity of at least one trunk group identity, further comprising the step of: said switch processor means selecting a trunk of said at least one trunk group for extending said call toward said destination.
Claim 14
Dependent Claim
71 words
The method of claim 12 wherein said telecommunications network comprises a plurality of SLPs, wherein said SLPs and said CPs are grouped into a plurality of SPPs (switching processing platforms), said SPPs each comprising a local data network for interconnecting processors of an SPP, wherein the step of transmitting said call setup request messages comprises the step of transmitting said call setup request messages over one of said local data networks.
Claim 15
Dependent Claim
58 words
The method of claim 14, wherein said telecommunications network comprises a plurality of swtiches and further comprises an interconnecting data network for interconnecting said SPPs and switches of said telecommunications network, and wherein the step of transmitting connection request messages comprises transmitting said connecting request messages over one of said local data networks and said interconnecting data network.
