Method and apparatus for identifying call records for a call in a cellular communication network
First Claim
1. A method for identifying call records for a call in a cellular communication network, comprising the steps of:
- assigning each call a unique identification code for identifying the call when the call is set up;
generating, at a first node, an originating call record comprising a first portion of call related information;
storing said identification code in a field in said originating call record in the first node;
forwarding said identification code to at least a second node in the network when the call is forwarded through at least the second node;
generating, at said at least one second node, at least one subsequent call record comprising subsequent portions of call related information; and
storing said identification code in a field in call records generated by at least said second node, wherein all call records for the call in the network are identifiable by at least a portion of the identification code so as to enable identification of said originating call record and said at least one subsequent call record as relating to the same call at postprocessing of call records generated at said first node and said at least one second node.

Abstract
A method and apparatus for identifying call records in such a manner as to make it possible for a post processing system to produce one bill based upon information stored in all of the produced call records independently of the node where the record is produced. A unique identification code is generated when a call is setup or when the call enters a network. The identification code is then transferred from node to node as the call is transferred from one node to another. Each node involved in the call produces a call record which contains at least a portion of the identification code. As a result, all of the call records produced for the call can be identified by the identification code stored in the call records.

20. A system for identifying call records for a call in at least one cellular communication network, comprising:
-
means for assigning each call a unique identification code for identifying the call when the call is set up; means for generating, at a first node, an originating call record comprising a first portion of call related information; storing means for storing said identification code in a field in said originating call record in a first node; means for forwarding said identification code to at least a second node in the network when the call is forwarded through at least the second node; means for generating, at said at least one second node, at least one subsequent call record comprising subsequent portion of call related information; and storing means for storing said identification code in a field in call records generated by at least said second node, wherein all call records for the call in the network are identifiable by at least a portion of the identification code so as to enable identification of said originating call record and at least one subsequent call record as relating to the same call at postprocessing of call records generated at said first node and said at least one second node. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method for identifying call records for a call in a cellular communication network, comprising the steps of:
-
forwarding a call through at least a first and a second node; generating at each node through which said call is forwarded a node identification code unique for each call and node; generating, at said first node, an originating call record comprising a first portion of call related information; storing said node identification code in a field in a call record which is generated at each node for said call; transferring said node identification code generated at a previous node to a next node; generating, at subsequent nodes, at least one subsequent call record comprising subsequent portions of call related information; and storing said transferred node identification code in a field in the call record generated at said next node, wherein the call records generated for the call are identified by a chain of node identification codes that are stored in the call records. - View Dependent Claims (39, 40, 44)

45. A method of assembling first call related billing information, being stored in a first call record generated at a first node, and second call related billing information stored in at least one second call record generated at at least one second node, for a single call in a cellular communication network comprising the steps of:
-
assigning the call an identification code which uniquely identifies the call when the call is set up; generating, at a first node, said first call record comprising a first portion of call related information; storing said identification code in a field in said first call record; forwarding said identification code to said at least one second node when the call is forwarded through said at least one second node; generating, at said at least second node, said at least one second call record comprising subsequent portions of call related information; storing said identification code in a field in said at least one second call record; and identifying said first call record and said at least one second call record as relating to the same call using said identification code.
