Abstract
Abstract A new session or handoff procedure is triggered for a mobile station in a communications network having a packet switched network connected to a wireless network. A data identifier from the wireless network is determined which indicates the location of the mobile station in the wireless network. A list maintained in a gateway connected between the wireless network and the packet switch network associates data identifiers of the packet switched network with data identifiers of the wireless network. The data identifier of the packet switched network indicating the location of the mobile station in the wireless network is determined using the list maintained in the gateway.

Claims Analysis
Total Claims: 36
Claim 1
Independent Claim
144 words
A method of triggering a new session or handoff procedure for a user equipment in a communications system having a second network connected to a first network, the method comprising the steps of: determining a first identifier from the first network indicating the location of the user equipment in the first network; providing said first identifier to an entity connected to said first network and to said second network, said entity associating a second identifier of the second network with said first identifier of said first network, the first identifier indicating the location of the user equipment in the first network and said second identifier indicating the location of the user equipment in the second network; and determining the second identifier of the second network indicating the location of the user equipment using said entity for associating said first identifier and said second identifier.
Claim 2
Independent Claim
144 words
A method of triggering a new session or handoff procedure for a user equipment in a communications system having a second network connected to a first network, the method comprising the steps of: determining a first identifier from the first network indicating the location of the user equipment in the first network; providing said first identifier to an entity connected to said first network and to said second network, said entity associating a second identifier of the second network with said first identifier of said first network, the first identifier indicating the location of the user equipment in the first network and said second identifier indicating the location of the user equipment in the second network; and determining the second identifier of the second network indicating the location of the user equipment using said entity for associating said first identifier and said second identifier.
Claim 3
Dependent Claim
34 words
The method as recited in claim 1 , wherein a controller obtains the first identifier of said first network, indicating the location of said user equipment in said first network, from the user equipment.
Claim 4

Claim 6
Dependent Claim
30 words
The method recited in claim 2 , wherein the user equipment updates its stored first identifier with the first identifier sent by the network from the controller to the entity.
Claim 7
Dependent Claim
30 words
The method recited in claim 5 , wherein said entity finds a correspondence between a previous first identifier from the first network and a second identifier from the second network.
Claim 8
Dependent Claim
27 words
The method recited in claim 5 , wherein a plurality of first identifiers from said first network correspond to a single second identifier from said second network.
Claim 9
Dependent Claim
40 words
The method recited in claim 6 , wherein said entity returns a registration reply to the controller after it has found a correspondence between said previous first identifier from the first network and a second identifier from the second network.
Claim 10
Dependent Claim
22 words
The method of claim 1 , wherein the first identifier is a PZ_ID parameter and the second identifier is a RA_ID parameter.
Claim 11
Dependent Claim
23 words
The method of claim 1 , wherein the first identifiers are PZ_ID and Cell-ID parameters and the second identifier is a RA_ID parameter.
Claim 12
Dependent Claim
21 words
The method recited in claim 8 , wherein a PPP connection is established between the user equipment and the said entity.
Claim 13
Dependent Claim
23 words
The method recited in claim 6 , wherein said entity sends an RA update request to a network element in the second network.
Claim 14
Dependent Claim
15 words
The method recited in claim 1 , wherein said entity is a wireless gateway (WGW).
Claim 15
Dependent Claim
23 words
The method recited in claim 12 , wherein said RA update request is sent over a standardized interface of said packet switched network.
Claim 16
Dependent Claim
26 words
The method recited in claim 14 , wherein said second network is a GPRS network and said network element is a Serving GPRS Support Node (SGSN).
Claim 17
Dependent Claim
22 words
