Embodiment Construction

[0064] The basic idea of ​​the present invention is: the base station generates the same pseudo-random number sequence as the terminal, and when determining the arrival of the paging group to which the terminal belongs, takes numbers from the pseudo-random number sequence in the same way as the terminal, and judges the paging group that the terminal belongs to. When the selected number is the set number, the paging message for the terminal is sent on the paging channel corresponding to the paging group, and correspondingly, the terminal receives the paging message on the paging channel.

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0066] The problem to be solved by the technical solution is to enable the terminal to increase the paging cycle without changing the existing GSM syste...

Abstract

The invention discloses a paging method comprising that a base station generates a pseudo random number sequence the same as a terminal; that the base station acquires numbers from the pseudo random number sequence in a manner the same as the terminal when it is determined that a paging set that the terminal belongs to comes, and transmits a paging message aimed at the terminal on a paging channel corresponding to the paging set when it is determined that the acquired number is a set number; and that the terminal receives the paging message on the paging channel correspondingly. The invention discloses a base station, a terminal, and a communication system. The base station may further enlarge the paging periods of all terminals in virtue of the value range of the random number. The terminal may calculate a time point to receive a next paging message according to the position of 0 in the pseudo random number sequence. Therefore, the terminal revives at a specific time point so as to monitor the paging channel and enters an idle state when not required to monitor the paging channel, thereby saving electricity.

Description

technical field [0001] The present invention relates to paging technology, in particular to a paging method, base station, terminal and system. Background technique [0002] figure 1 A schematic diagram of a hierarchical frame structure for the Global System of Mobile Communication (GSM, Global System of Mobile communication), such as figure 1 As shown, the wireless frame structure of GSM includes five levels, that is, slot, Time Division Multiple Access (TDMA, Time Division Multiple Access) frame, multiframe, superframe and hyperframe. A time slot is the basic unit of a physical channel; a TDMA frame is composed of 8 time slots and is the basic unit occupying the carrier frequency bandwidth, that is, each carrier frequency has 8 time slots; there are two types of multiframes: (1) A multiframe composed of 26 TDMA frames, which is used for traffic channel (TCH, Traffic Channel), slow associated control channel (SACCH, Slow Associated Control Channel) and fast associated con...
