US 10,477,512 B2 · Telecommunications apparatus and methods for paging mobile terminals in a wireless communication system

Abstract

A method of paging in a wireless telecommunications system. A core network element selects a base station from plural base stations including a tracking area to have primary responsibility for paging a terminal device and conveys an indication of the terminal device to the selected base station. Each base station maintains a paging database identifying one or more terminal devices for which it has a responsibility for paging. When a terminal device is to be paged, the core network element transmits a paging request to the plural base stations including the tracking area. The respective base stations then determine whether to onward transmit a paging message for the terminal device based on a comparison between an identifier for the terminal device being paged with entries in their paging database, and if the comparison indicates it has responsibility for paging the terminal device, it will transmit a paging message accordingly.

Dependent claims

A method of operating a base station in a wireless telecommunications system comprising a core network, a plurality of base stations and a plurality of terminal devices, the method comprising:

identifying one or more terminal devices for which the base station is to have a responsibility for paging based on an indication of the one or more terminal devices, the indication being received by the base station from the core network;
maintaining a paging database identifying the one or more terminal devices for which the base station is to have a responsibility for paging based on the indication received from the core network;
receiving, from the core network, a paging request in a separate transmission from the indication, the paging request conveying an identifier for a terminal device being paged in the wireless telecommunications system;
determining to transmit a paging message for the terminal device being paged when the identifier for the terminal device being paged matches an entry in the paging database;
and
determining to take no further action with respect to the paging message when the identifier for the terminal device being paged does not match an entry in the paging database.

3 more elements

A base station for use in a wireless telecommunications system comprising a core network, a plurality of base stations and a plurality of terminal devices, wherein the base station is configured to:

identify one or more terminal devices for which the base station is to have a responsibility for paging based on an indication of the one or more terminal devices, the indication being received by the base station from the core network;
maintain a paging database identifying the one or more terminal devices for which the base station is to have a responsibility for paging based on the indication received from the core network;
receive, from the core network, a paging request in a separate transmission from the indication, the paging request conveying an identifier for a terminal device being paged in the wireless telecommunications system;
determine to transmit a paging message for the terminal device being paged when the identifier for the terminal device being paged matches an entry in the paging database;
and
determining to take no further action with respect to the paging message when the identifier for the terminal device being paged does not match an entry in the paging database.
