Embodiment approach 200

[0023] As shown, at 210 the terminal device 110 receives a CBS message from the network device 120 . According to implementations of the subject matter described herein, CBS messages may be sent from network device 120 to terminal device 110 in various ways. For example, in some implementations, CBS messages may be received from network device 120 via a broadcast and multicast control (BMC) protocol layer on a common traffic channel (CTCH) logical channel. CBS messages may be received on the CTCH using Discontinuous Reception (DRX). It should be understood that the above examples are discussed for illustration only and not limitation. There may be several other implementations for the terminal device 110 to receive CBS messages.

[0024] At 220, attributes of the CBS message are determined. Attributes of a CBS message indicate characteristics of the CBS message, such as the type of CBS message, the content of the CBS message, the events carried by the CBS message, the time ...

Abstract

According to implementations of the subject matter described herein, a new approach for receiving the CBS message is proposed. Generally speaking, in response to receiving a CBS message from a networkdevice, a terminal device will determine an attribute of the CBS message. Then, the terminal device will determine a policy for receiving a further CBS message based on the determined attribute. Thatis, the policy is determined through a self-learning process performed on the received CBS message (s). In this way, the power consumption of the terminal device for receiving the CBS messages can bereduced. As a result, the battery life of the terminal device can be guaranteed.

Description

Background technique [0001] Cell Broadcast Service (CBS) is designed for simultaneous delivery to multiple users in a specified area and is a technology that allows a cell operator to broadcast messages to terminal devices in a cell(s). CBS messages may contain information related to traffic, weather, general advertisements, emergency related messages, and the like. The geographical scope of a CBS message can be a cell of a public land mobile network (PLMN), a group of cells in a PLMN, or the entire PLMN. Terminal devices in the PLMN can receive CBS messages broadcast from network devices. For a terminal device, a CBS message may be received when the CBS function on the device is activated. In other words, unless the CBS function is enabled, the terminal device cannot receive any CBS messages. However, if the CBS function is enabled for a long period of time, the power consumption of the terminal device will be very high. Contents of the invention [0002] In general, a ...
