Problems solved by technology

[0008] However, according to the current way of sending broadcast messages, when the broadcast cycle is long, the number of users in the target group is small and the number of messages is large, a large number of broadcast messages will still be sent on the paging channel, resulting in the overload of the paging channel

Embodiment Construction

[0034] The embodiment of the present invention provides a method for sending a broadcast message. Before sending a broadcast message to a target group, the base station queries the number of users of the target group, and determines that the number of users is less than the threshold value of the number of users of the target group and satisfies the The conditions for sending broadcast messages in consecutive time slots are to use the IMSI (International Mobile subscriber Identity) of the terminals in the target group to obtain the carrier frequency, paging channel, and number of time slots monitored by the terminal through a hash algorithm. The broadcast message is sent on the time slot monitored by the terminal. When multiple terminals in the group monitor the same carrier frequency and the same time slot of the same paging channel, only one paging message needs to be sent.

[0035] Whether the system sends broadcast messages in the way of continuous time slots or broadcast ...

Abstract

The present invention discloses a method for sending broadcast messages and a base station. The method for sending broadcast messages includes: the target group at the side direction of the base station firstly enquiring the subscriber number in the target group before sending the broadcast message; when the subscriber number is determined to be less than the preset threshold and the subscriber number satisfies the condition of the broadcast message continuous transmission mode, using the international mobile subscriber identity IMSI of the subscriber terminal in the target group to compute the channel resource monitored by the subscriber terminal through Hash algorithm, and transmitting the broadcast message on the obtained channel resource. Application of the inventive method can reduce the transmission amount of the paging channel redundant message to achieve the objective of reducing the paging channel load.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for sending broadcast messages and a base station. Background technique [0002] In the current wireless communication system, the paging channel resource, as one of the important resources in the entire communication system, undertakes the task of sending various paging messages. The paging channel mainly transmits three types of messages: [0003] (1) Overhead message. The overhead message includes information required for terminal access to the system and call establishment, and is updated periodically. [0004] (2) Call-related messages mainly include general paging message GPM (General Page Message), extended channel assignment message ECAM (Extended Channel Assignment Message) and base station confirmation message, etc. [0005] (3) Broadcast message, which is a message sent on all cells, all carrier sectors, and all paging channels specified by the...
