Abstract
Abstract A system and method of paging mobile stations in a cellular telecommunications network that reduces signaling traffic by reducing the number of page messages sent from a Mobile Switching Center (MSC) to Base Stations (BSs) in the network. The MSC sends a single Internet Protocol (IP) broadcast page message over an IP network to which the BSs are connected. User Datagram Protocol (UDP) ports in each BSs are dedicated to listening for IP broadcast page messages directed to a given BS's associated location area, location area group, or the network service area.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
95 words
A method of paging mobile stations in a cellular telecommunications network having a Mobile Switching Center (MSC), a plurality of Base Stations (BSs) in a network service area, and an Internet Protocol (IP) network connecting the BSs to the MSC, said method comprising the steps of: assigning a common IP broadcast address to all of the BSs in the service area; broadcasting an IP page message to the common IP broadcast address; and dedicating at least one User Datagram Protocol (UDP) port in each of the BSs to receive the page message from the MSC.
Claim 2
Independent Claim
95 words
A method of paging mobile stations in a cellular telecommunications network having a Mobile Switching Center (MSC), a plurality of Base Stations (BSs) in a network service area, and an Internet Protocol (IP) network connecting the BSs to the MSC, said method comprising the steps of: assigning a common IP broadcast address to all of the BSs in the service area; broadcasting an IP page message to the common IP broadcast address; and dedicating at least one User Datagram Protocol (UDP) port in each of the BSs to receive the page message from the MSC.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein the step of dedicating at least one UDP port in each of the BSs includes dedicating a first UDP port to receive page messages directed to a location area with which the BS is associated.
Claim 4
Dependent Claim
49 words
The method of claim 2 wherein the step of dedicating a first UDP port to receive page messages directed to a location area includes assigning each BS a first unique port number on which to receive page messages being sent to all BSs in each BS's associated location area.
Claim 5
Dependent Claim
42 words
The method of claim 3 wherein the step of dedicating at least one UDP port in each of the BSs includes dedicating a second UDP port to receive page messages directed to a location area group with which the BS is associated.
Claim 6
Dependent Claim
51 words
The method of claim 4 wherein the step of dedicating a second UDP port to receive page messages directed to a location area group includes assigning each BS a second unique port number on which to receive page messages being sent to all BSs in each BS's associated location area group.
Claim 7
Dependent Claim
36 words
The method of claim 5 wherein the step of dedicating at least one UDP port in each of the BSs includes dedicating a third UDP port to receive page messages directed to the network service area.
Claim 8
Dependent Claim
49 words
The method of claim 6 wherein the step of dedicating a third UDP port to receive page messages directed to the network service area includes assigning each BS a third unique port number on which to receive page messages being sent to all BSs in the network service area.
Claim 9
Dependent Claim
110 words
The method of claim 7 wherein the step of broadcasting an IP page message to the common IP broadcast address includes the steps of: broadcasting an IP page message that is addressed to the first port number when the page message is being sent to all BSs in the associated location area; broadcasting an IP page message that is addressed to the second port number when the page message is being sent to all BSs in the associated location area group; and broadcasting an IP page message that is addressed to the third port number when the page message is being sent to all BSs in the network service area.
Claim 10
Dependent Claim
41 words
The method of claim 8 wherein the third port number is 10000, the second port number is a number in the range of 10001 to 10032, and the third port number is a number in the range of 10101 to 10116.
Claim 11
Dependent Claim
34 words
The method of claim 1 wherein the step of dedicating at least one UDP port in each of the BSs to receive the page message includes utilizing a hardware device to dedicate the port.
Claim 12
Dependent Claim
34 words
The method of claim 1 wherein the step of dedicating at least one UDP port in each of the BSs to receive the page message includes utilizing a software method to dedicate the port.
Claim 13
Independent Claim
88 words
A system for paging mobile stations in a cellular telecommunications network having a Mobile Switching Center (MSC) serving a network service area and a plurality of Base Stations (BSs) having a common Internet Protocol (IP) broadcast address, said system comprising: an IP network connecting the BSs to the MSC; means in the MSC for broadcasting an IP page message to the common IP broadcast address; and at least one User Datagram Protocol (UDP) port in each of the BSs dedicated to receiving the page message from the MSC.
Claim 14
Independent Claim
