Paging method, location update method and device
First Claim
1. A paging method, wherein the method comprises:
- receiving, by an eNodeB, a paging message, wherein the paging message carries a tracking area identity;
paging, by the eNodeB, a user equipment if the tracking area identity in the paging message is the tracking area identity of the eNodeB; and
instructing, by the eNodeB, a relay to page the user equipment if the tracking area identity in the paging message is the tracking area identity of the relay of the eNodeB.

Abstract
A paging method may reduce signaling overhead of system paging and save system paging resources. The method includes: receiving, by an eNodeB, a paging message, where the paging message carries a tracking area identity; paging a user equipment if the tracking area identity in the paging message is the tracking area identity of the eNodeB; and instructing a relay to page. A location update method is also disclosed, which reduces signaling load produced by location update. The method includes: generating, by a relay, a system message, where the system message includes a tracking area identity of the relay; and broadcasting the system message, and triggering a user equipment in a cell of the relay to initiate a location update request. The embodiments of the present invention disclose an eNodeB, a relay, a communication system.
