Description

METHOD AND APPARATUS FOR FOLLOWING THE HISTORY OF CALLS FOR MOBILE AND WIRELESS USERS ACCESSING THE NETWORK IN DIFFERENT GATES FOR SUBSEQUENT CALLS Field of the Invention This invention relates to call history tracking for physical line users and updating this information in new switches, as dynamic line allocation is employed. This invention also applies to mobile users as the calling user is transferred between mobile switching centers when a mobile user operates outside their service area. Background Usually, there are several services offered by telecommunications providers where the history of previous calls of the line gate used by the subscriber is used as power data. Examples of these services include automatic return calls, automatic redial, and client origin tracking. The automatic return call service allows a user to direct a call to the last party the user will call. The automatic callback service allows a user to direct a call to the same number last called by the user. And, the tracking originated by the client allows a user REF .: 30231 to request an automatic follow-up of the last incoming call. For these types of services, saving the history of a user's calls is achieved by saving the call history data as it relates to a particular line gate. There is a need to store call history referring to users against line gates. This is important because certain categories of users may not use the same line gates for subsequent calls. These users include mobile subscribers served by a set of lines in the central, physical line subscribers served by a set of lines in the plant where there are many subscribers with respect to a lower number of gates (possibly for economic reasons in the case of suppliers of competitive access), personal mobility service by means of physical line telephones (smart cards that identify the person in "public" telephones), and mobile subscribers in a mobile switching center where the line gates are not used. Therefore, there is a need to track and store call history as it relates to a subscriber number instead of a line gate. COMPENDIUM OF THE INVENTION This invention provides a method and apparatus for associating call data with particular users instead of line gates. This call data includes the latest incoming and outgoing calls associated with a particular telephone. This allows services such as automatic return call and automatic call back and tracking originated by client, be implemented without consideration to the line gate allowing users to maintain the same level of services subscribed in different sites. For mobile users, automatic call back, automatic call back and customer originated tracking can be implemented with the mobile switching center as well as mobile switching centers that operate outside their service area. If the mobile user operates outside their service area, at least two schemes can be deployed to update the mobile switching center with call history information. First, when the mobile station registers with a mobile switching center, the previous mobile switching center transmits the call history to the new mobile switching center. Secondly, when the mobile station is registered with a mobile switching center, the location record of its service area or the wireless intelligent network obtains the call history information of the previous mobile switching center and transmits this information to the new one. mobile switching center.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS FIG. 1 illustrates a block diagram of the prior art of a switching center with call history associated with line gates. In prior art systems, subscriber telephones 10 are connected by twisted pair lines 12 to line gates 14 located in the switching system 16. Each line gate 14 is connected and associated with a specific subscriber telephone line 12. Call history information is stored in the memory of the switching system and associates call history information such as last called number and last number called with each gateway ID of line 18. Figure 2 illustrate a block diagram of a switching system with a call history based on intelligent network. A subscriber telephone 20 is connected to a line concentrator 22 which contains a plurality of line or gate cards by a twisted pair 24. A line concentrator 22 is an interface that allows low usage subscriber lines to connect to the high usage channels. Another telephone 26 and line concentrators 22 are connected to the switching systems 28 in the line gates 31 and 32. The switching system 28 can store in memory information regarding the tracking of each telephone independent of the gate or line card . Each switching system 28 can support a plurality of line gates 30 and 31. Advanced intelligent network triggers 33 are assigned to each line gate 30. The switching system 28 as well as other switching systems 37 are connected to a switching node. intelligent network 34. The intelligent network node 34 assists in the transfer and storage of call history information such as subscriber ID, last incoming call number, and the last outgoing call number. For example, as a user 36 disconnects the switching system 28, the call history information that is associated with a particular subscriber is tracked by the intelligent network node 34 by originating and terminating triggers. As other users 20 attempt to access the switching system 28, the line gate 30 previously used by the user 36 is now available to the user 20 in the switching system 28. Since the smart network node 34 tracks the history of calls of the users and not to the line gates, the physical equipment can be optimized through the switching system 28. FIG. 3 illustrates a block diagram of tracking the history of calls for wireless subscribers by means of a wireless intelligent network. When the mobile user 38 connects to the mobile switching center (MSC = Mobile Switching Center) 40 through the base station 42, the wireless smart network triggers are sent to the wireless intelligent network node service control point (WIN / HLR = ireless Intelligent Net ork Node Service Control Point) 44 by the MSC 40. As the mobile user 38 travels to a point where the mobile switching center 40 terminates service and transfers service to the user 38 to a different MSC 46, the WIN / SCP 44 updates the call history and any additional information from the home location register (HLR = Home Location Register) to the new MSC 46. This information is provided to and from WIN / SCP 44 by origin and termination triggers.

Figure 4 illustrates a block diagram for transferring call history information to the various mobile switching centers. When a mobile user activates or turns on the cell phone (mobile station) 50, a registration message is sent from the mobile station 50 to the base station 52. A series of base stations is connected to an MSC 54. When the mobile user directs or receives a telephone call, the call history information is updated in the MSC 54. When the mobile station 50 goes to the outside range of the MSC 54, the mobile station 50 registers in the MSC 60 that is closest and is capable of support the mobile station 50. The MSC 60 sends a registration message to the WIN / SCP 56. There are at least two schemes for transferring call history information to the new MSC 60. First, the WIN / HLR 56 informs the second MSC 60 of the location of the most recent VLR for the mobile station 50 which specifies the MSC 54. The MSC 60 sends a request to the MSC 54 for the most recent VLR and call history associated with the mobile station 50. This information is sent by the MSC 54 to MSC 60 and MSC 54 removes the VLR corresponding to mobile station 50. In second, WIN / HLR 56 builds a new VLR for mobile station 50 in the second MSC 60. A cancellation message is sent from WIN / HLR 56 to the first MSC 54. As part of cancellation, the MSC 54 transmits the call history associated with the mobile station 50 to the WIN / HLR 56. The second MSC 60 receives the VLR including the call history from the WIN / HLR 56 Figure 5 illustrates a flowchart of messages for originating and terminating calls and the associated updating of call history information. When a user 100 receives an incoming call from another party in the PSTN 102 and the call is terminated 103 to the switch B 106. The switch B 106 sends a termination message 107 with the call digits to the intelligent network node 108. The The smart network node 108 updates the call history information 111 with the telephone number of the other party calling the user 100. A trigger response 109 is sent by the smart network node 108 to the switch B 106. The switch B 106 terminates the call 110. When the user 100 originates a call 112, an origin trigger with the called number 112 is sent by the switch B 106 to the smart grid node 108. The smart network node 108 updates the history information of calls with the called number 116. The smart network 116 transmits a trigger response to the switch B 106 and the call of origin 120 is placed in the PSTN 102. Figure 6 illustrate a flow chart of messages for the automatic return call service when a user using dynamic line assignment moves to a new switch. With dynamic line allocation, a subscriber to a particular set of services has access to those services in different locations. For example, a subscriber who has subscribed to an automatic return home service can have the service while on a business trip. When the user 100 of Figure 5 invokes automatic return call service elsewhere, a source signal 122 is sent to the switch A 124. The switch A 124 transmits an origin trigger 126 to the smart network node 108. The intelligent network node 108 recognizes the automatic return call service code, and retrieves the last dialed number of entry for user 100. Intelligent network node 108 transmits a trigger response with the last number dialed entry 128 to the switch A 124. The switch A 124 directs the origin call 130 to the last dialed number. Figure 7 illustrates a message flow diagram for automatic redial service when a user moves to a new switch. When the user 100 of Figure 7, invokes the automatic call back service at another site, a source signal 132 is sent to switch A 124. Switch A 124 transmits a source trigger 134 to smart grid node 108. Intelligent network node 108 recognizes the automatic redial service code, and retrieves the last dialed output number for user 100. Intelligent network node 108 transmits a trigger response with the last dialed output number 136 to switch A 124. Switch A 124 directs originating call 138 to the last dialed number. Figure 8 illustrates a message flow diagram for updating and tracking call history information in a wireless network. When a mobile user 200 receives an incoming call from another party in the PSTN 202 and the call is terminated 203 to the MSC B 204, MSC B204 transmits a termination message 207 with the call digits to the wireless intelligent network node 208. The wireless smart network node 208 updates the call history information 211 with the telephone number of the other party calling the user 200. A trigger response 209 is sent by the wireless smart network node 208 to the MSC B 206. The MSC 206 ends the call 210.

When the user 200 originates a call 212, an origin trigger with the called number 214 is sent by MSC B 206 to the wireless smart network node 208. The wireless intelligent network node 208 updates the call history information with the called number 216. The wireless smart network 216 transmits a trigger response to MSC B 206 and an origin call 220 is placed in the PSTN 202. Figure 9 illustrates a message flow diagram for automatic call back service, when a user Mobile moves to another MSC. When the mobile user 200 of Figure 8 invokes the automatic return call service at another site, a source message 222 is sent to MSC A 224. The MSC A 224 transmits a source trigger 226 to the wireless intelligent network node 208. The wireless intelligent network node 208 recognizes the automatic return call service code and retrieves the last dialed number of entry for the user 200. The wireless intelligent network node 208 transmits a trigger response with the last number dialed. entry 228 to MSC A 224. MSC A 224 directs source call 230 to the last dialed number. Figure 10 illustrates a message flow diagram for automatic redial service when a mobile user moves to another MSC. When the mobile user 200 of Figure 8 invokes the automatic callback service in another MSC, a source message 222 is sent to the MSC A 224. The MSC A 224 transmits a source trigger 226 to the wireless intelligent network node 208.
