Embodiment Construction

[0023] This section will describe the present invention in detail with reference to the accompanying drawings.

[0024] refer to figure 1 A paging method in high penetration mode in a satellite mobile communication system, the satellite mobile communication system includes an earth mobile terminal, a communication satellite, a ground access network and a core network; the earth mobile terminal is connected to the ground access network through a communication satellite network, the terrestrial access network is connected to the core network, and the core network includes voice services in the CS domain, and is described in detail as follows:

[0025] The process for the earth mobile terminal to enter and exit the high penetration mode is as follows:

[0026] S101: The earth mobile terminal regularly detects the normal synchronization signal, and if it can be detected, enters the normal service state;

[0027] S102: The earth mobile terminal cannot detect a normal synchronizat...

Abstract

The invention relates to the technical field of communication, and provides a paging method and device in a high penetration mode in a satellite mobile communication system. The method comprises the following steps: an earth mobile terminal signal cannot detect a normal FCCH (Frequency Correction Channel) signal and a BCCH (Broadcast Control Channel) signal, but can detect a BACH (Basic Alarm Channel) signal, and the earth mobile terminal enters a high penetration state; a core network sends a normal paging message when paging the earth mobile terminal, and sends a high-penetration paging message when a paging response is not received within the duration of the timer; when the earth mobile terminal is in a high-penetration state and receives high-penetration paging, the earth mobile terminal is prompted to move to an open strong signal area so as to recover to a normal service state; the high-penetration scene enables the earth mobile terminal to receive paging under the condition of weak signals, so the use coverage scene of the whole satellite mobile communication system is perfected, the use effect of a user is improved, and the performance efficiency of the whole system is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a paging method and device in a high penetration mode in a satellite mobile communication system. Background technique [0002] In the satellite mobile communication system, due to the characteristics of the entire system, when the signal strength is weak, the earth mobile terminal will not be able to receive normal FCCH and BCCH, and cannot perform normal business. In order to improve this scenario, the earth mobile terminal can monitor the dedicated channel BACH with high penetration characteristics, on which the earth mobile terminal can synchronize with the system, and can receive high penetration paging on this channel to This is to achieve that in the case of a weak signal, the earth mobile terminal can also receive the paging message. By reminding the user that it is currently in a high-penetration state and receiving a high-penetration page, the user moves ...
