Paging cancel procedure in a telecommunications system

摘要

Disclosed is a paging control method in a telecommunications system where devices are paged by paging requests from base stations, the base stations being controlled by paging control messages from a network node. The method involves detecting (310), in the network node, a need to initiate paging of a device. Then, a set of candidate base stations in an area of the telecommunications system is determined (320) by the network node. The candidate base stations are potentially capable of reaching the device in the area by sending paging requests at respective paging occasions. The network node selectively controls (330) paging control messages intended for the set of candidate base stations depending on detection of a paging response made by the device via one of the base stations in the set of candidate base stations, so as to prevent paging requests from base stations, in the set of candidate base stations, which have not yet sent any paging requests to the device.

1. A paging control method in a telecommunications system where devices are paged by paging requests from base stations, the base stations being controlled by paging control messages from a network node, the method comprising, in said network node:
detecting a need to initiate paging of a device; determining a set of candidate base stations in an area of said telecommunications system, the candidate base stations being potentially capable of reaching said device in said area by sending paging requests at respective paging occasions; and controlling paging of the device from the set of candidate base stations by sending paging control messages to successive ones of the base stations in the set of candidate base stations according to a sequence corresponding to next paging occasions at the base stations, and refraining from sending the paging control messages to any further base stations in the sequence, in response to detecting a paging response from the device, thereby preventing the any further base stations from paging for the device.
