SELECTIVE PAGING IN WIRELESS NETWORKS
First Claim
1. A gateway in a communication network that receives packets destined for user equipment comprising:
- an interface configured to receive a packet destined toward a user equipment; and
an interface configured to initiate a page request,wherein the gateway is configured to determine, based on information from the packet, which user equipment the packet is destined for and for qualifying the packet to initiate a page request to the user equipment, wherein the packet is qualified when the user equipment is in an idle state and wherein the packet passes a qualification procedure that includes inspecting the packet according to one or more rules to determine whether the packet is eligible for transmission to the user equipment, wherein the gateway refrains from paging the user equipment if the packet is not qualified.

Abstract
A method and system for selectively paging user equipment in a communication network is disclosed. The selective paging is implemented with a set of rules that determine whether a packet triggers a page request to user equipment. The rules can be dynamic and can discard unwanted packets to avoid waste of system resources, disruptions in service, and draining of a user equipment'"'"'s battery life. The selective paging can be implemented on a serving gateway (SGW), a packet data network gateway (PGW), a mobility management entity, or a combination of the three. The selective paging can use information regarding the state of the user equipment and other rule-based criteria to determine whether packets received by a gateway trigger a page of the user equipment.

8. A method of selective paging at a gateway in a communication network, the method comprising:
-
receiving a packet at the gateway; determining to which user equipment the packet is destined; accessing state information for that user equipment; initiating, at the gateway, a qualifying procedure on the packet when the user equipment is in an idle state and the packet would trigger a page request; inspecting the packet as part of the qualifying procedure according to rules to determine whether the packet is eligible to trigger a page request to the user equipment; and sending a page request to the user equipment when the packet is determined to be eligible for transmission and refraining from sending the page request when the packet is determined to be ineligible for transmission. - View Dependent Claims (9, 10, 11, 12, 13, 14)

- 15. A gateway in a communication network that receives packets destined for user equipment, the gateway is configured qualify the packet to determine whether a page request should be sent to the user equipment by determining which user equipment the packet is destined for and whether the user equipment is in an idle state, and wherein the packet undergoes a qualification procedure based on an inspection according to one or more rules, wherein the gateway refrains from paging the user equipment if the packet is not qualified.
