Abstract

Abstract A mobile station (10) can be selectively coupled to two or more networks (102, 153). By maintaining an address translation table (220) and introducing communication between the switching control units (201, 252) within the multiple networks, it is possible to provide notification to the mobile station (10) of the existence of a communication request from a first network (153) while the mobile station (10) is coupled to the second network (102). <IMAGE>

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 129 words
In a communication system comprising a first network and a second network wherein a mobile station is capable of being coupled to either one of the first and second networks, a method for notifying the mobile station of a communication on a network to which the station is not presently coupled, the method comprising the steps of: storing an address for the mobile station as it is coupled to one of said first and second networks; receiving a communication request from that one of said first and second networks to which the mobile station is not presently coupled; using the stored address of the mobile station as it is coupled to one of said first and second networks to send an alert that said communication request has been received.
Claim 2
Dependent Claim 46 words
The method of claim 1 wherein said step of storing comprises the steps of: detecting when the mobile station changes the network to which it is coupled; and updating a memory with an address of the mobile station in the network to which it is coupled.
Claim 3
Dependent Claim 21 words
The method of claim 1 wherein said first network is a voice network and said second network is a paging network.
Claim 4
Dependent Claim 21 words
The method of claim 1 wherein said first network is a voice network and said second network is a data network.
Claim 5
Dependent Claim 45 words
The method of claim 4 wherein; the mobile station is initially coupled to said first network; said step of storing occurs after the mobile station changes its coupling to the second network; and said step of receiving receives a communication request from said first network.
Claim 6
Dependent Claim 18 words
The method of claim 4 wherein the step of receiving receives a communication request from said second network.
Claim 7
Dependent Claim 45 words
The method of claim 4 wherein; the mobile station is initially coupled to said second network; said step of storing occurs after the mobile station changes its coupling to said first network; and said step of receiving receives a communication request from said first network.
Claim 8
Dependent Claim 14 words
The method of claim 4 wherein said data network is a packet data network.
Claim 9
Dependent Claim 21 words
The method of claim 4 wherein said first network is a voice network and said second network is a paging network.
Claim 10
Dependent Claim 15 words
The method of claim 1 wherein said alert includes information regarding said received communication request.
Claim 11
Dependent Claim 18 words
The method of claim 10 wherein said information includes how the mobile station should connect to the communication.
Claim 12
Dependent Claim 118 words
In a wireless communication system comprising a voice network and a data network, wherein a mobile station can camp onto the voice network via a first control channel and can camp onto the data network via a second control channel, a method for notifying the mobile station of a communication from the voice network while it is camped on the data network, the method comprising the steps of: storing an address for the mobile station as it is camped on the data network; receiving a communication request for the mobile station from the voice network; using the stored address of the mobile station to send an alert via said data network that said communication request has been received.
Claim 13
Dependent Claim 118 words
In a wireless communication system comprising a voice network and a data network, wherein a mobile station can camp onto the voice network via a first control channel and can camp onto the data network via a second control channel, a method for notifying the mobile station of a communication from the data network while it is camped on the voice network, the method comprising the steps of: storing an address for the mobile station as it is camped on the voice network; receiving a communication request for the mobile station from the data network; using the stored address of the mobile station to send an alert via said voice network that said communication request has been received.
Claim 14
Dependent Claim 84 words
A communication system for permitting communication requests to follow a mobile station after it changes networks, the system comprising: memory storing an address of a mobile station on a network to which it is coupled; a communication receiver that receives a communications request on a network to which the mobile station is not coupled; and a processor, coupled to said memory and said communication receiver and using said address of the mobile station to alert the mobile station that said communication request was received.
Claim 15
Dependent Claim 31 words
The system of claim 14 wherein the mobile station is coupled to a voice network and then changes to a data network, said communication request being received by said voice network.
Claim 16
Dependent Claim 31 words
The system of claim 14 wherein the mobile station is coupled to a data network and then changes to a voice network, said communication request being received by said data network.
Claim 17
Dependent Claim 55 words
A wireless communication system for forwarding communication requests across networks comprising: a voice network including a mobile switching center; a data network including a mobile data intermediate system; a memory coupled to said voice network and said data work and storing address information for the mobile station as it is camped on said data network.
Claim 18
Dependent Claim 48 words
The system of claim 17 further comprising a processor coupled to said voice network and said memory that, upon receipt of a communication request on said voice network accesses the stored address information for the mobile station and notifies the mobile station of receipt of said communication request.
Claim 19
Dependent Claim 22 words
The system of claim 18 wherein notification of the mobile station of receipt of said communication request includes information regarding the communication.
Claim 20
Dependent Claim 18 words
The method of claim 19 wherein said information includes how the mobile station should connect to the communication.
