US 2017/0374491 A1 · METHOD FOR INSTRUCTING UPDATE OF SYSTEM INFORMATION, BASE STATION AND USER EQUIPMENT

Abstract

Provided are a method for instructing update of machine type communication (MTC) system information, a base station (BS) supporting MTC, and a user equipment (UE). The MTC system information comprises system information required by a first-type MTC UE and system information required by a second-type MTC UE. The method comprises: when system information required by a first-type MTC UE is updated and/or system information required by a second-type MTC UE is updated, generating an instruction message containing a related MTC system information update instruction identifier; and sending the generated instruction message. The embodiments of the present invention can reduce the number of times an MTC UE reads the system information, thereby saving on the energy consumption of the MTC UE.

A method for sending an update indication of machine type communication MTC system information, wherein the MTC system information comprises system information required by a first type of machine type communication user equipment MTC UE and system information required by a second type of machine type communication user equipment MTC UE, the method comprises:

generating an indication message containing an update indication identifier of the MTC system information when the system information required by the first type of MTC UE has been updated and/or the system information required by the second type of MTC UE has been updated;
and
sending the generated indication message.

A method for receiving an update indication of machine type communication MTC system information, wherein the MTC system information comprises system information required by a first type of user equipment UE and system information required by a second type of user equipment UE, and the method comprises:

receiving an update indication message of the MTC system information from a base station:
extracting an update indication identifier of the MTC system information from the update indication message of the MTC system information;
and
determining whether the system information required by the first type of MTC UE and/or the system information required by the second type of MTC UE has been updated according to the extracted update indication identifier of the MTC system information.

1 more element

A base station supporting machine type communication, comprising:

an MTC system information update indication generation module configured to generate an indication message containing an update indication identifier of MTC system information when system information required by a first type of machine type communication user equipment MTC UE has been updated and/or system information required by a second type of machine type communication user equipment MTC UE has been updated,
wherein the MTC system information contains the system information required by the first type of MTC UE and the system information required by the second type of MTC UE, and
a communication module configured to send the generated indication message.
