Abstract
Abstract A method of allocating an Internet Protocol (IP) address to a mobile wireless terminal 7 within a mobile telecommunications network. The network repeatedly broadcasts, over a radio broadcast channel of the network, a routing prefix corresponding to the Radio Network Controller (RNC) ID. Mobile terminals 7 listen to the broadcast channel, either when registering with the network or subsequently thereto, to determine the routing prefix. A mobile terminal 7 combines the routing prefix with a host port to generate an IP address for subsequent Internet sessions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A method of allocating an Internet protocol (IP) address to a mobile wireless terminal within a mobile telecommunications network, the method comprising repeatedly broadcasting at least a routing prefix over a radio channel of the network, wherein the routing prefix may be received by a mobile terminal listening to said radio channel and thereafter incorporated into an IP address.
Claim 2
Independent Claim
59 words
A method of allocating an Internet protocol (IP) address to a mobile wireless terminal within a mobile telecommunications network, the method comprising repeatedly broadcasting at least a routing prefix over a radio channel of the network, wherein the routing prefix may be received by a mobile terminal listening to said radio channel and thereafter incorporated into an IP address.
Claim 3
Dependent Claim
22 words
A method according to claim 1 , wherein the routing, prefix broadcast by the mobile network is unique to the radio network.
Claim 4
Dependent Claim
42 words
A method according to claim 1 , wherein the broadcast routing prefix is unique to a node of the radio network, such as a Base Station Controller (BSC) of a GSM network or a Radio Network Controller (RNC) of a GPRS/UTS network.
Claim 5
Dependent Claim
27 words
A method according to claim 1 , wherein the mobile telecommunications network uses GPRS or UMTS protocols over the air interface coupling mobile terminals to the network.
Claim 6
Dependent Claim
21 words
A method according to claim 1 , wherein said routing prefix is transmitted over a broadcast channel of the mobile network.
Claim 7
Dependent Claim
68 words
Apparatus for allocating an Internet Protocol (IP) address to a mobile wireless terminal within a telecommunications network, the apparatus comprising means for continuously broadcasting at least a routing prefix of an IP address over the air interface of the telecommunications network, and means associated with the mobile terminal for listening to said broadcasts to obtain the routing prefix and for generating an IP address using the routing prefix.
Claim 8
Dependent Claim
68 words
Apparatus for allocating an Internet Protocol (IP) address to a mobile wireless terminal within a telecommunications network, the apparatus comprising means for continuously broadcasting at least a routing prefix of an IP address over the air interface of the telecommunications network, and means associated with the mobile terminal for listening to said broadcasts to obtain the routing prefix and for generating an IP address using the routing prefix.
Claim 9
Dependent Claim
48 words
An Internet enabled mobile wireless terminal, the mobile terminal being arranged in use to listen to a radio channel of a mobile telecommunications network and to obtain from the radio channel a broadcast routing prefix which can be used by the mobile terminal to generate an IP address.
Claim 10
Dependent Claim
48 words
An Internet enabled mobile wireless terminal, the mobile terminal being arranged in use to listen to a radio channel of a mobile telecommunications network and to obtain from the radio channel a broadcast routing prefix which can be used by the mobile terminal to generate an IP address.
