Abstract

The system is featured as the follows. At least one short message gateway is connected to two or above two signaling transfer points of mobile network as well as to two or above two short message centres. It can be made a spare gateway for some other short message centre gateway since the short message centre gateway is connected with above one signaling transfer points so that chaining to be switched to preset backup short message centre can be ensured by utilizing global code address varying function when certain short message centre signaling gateway if fault. The same as above, short message can be retransmitted to spare short message centre for processing when certain short message centre is fault since short message gate way is also connected with spare short message centre in addition to its mainly used short message centre.

Description

Technical field:

[0001] The invention relates to a short message system. Background technique:

[0002] The current short message system running on the mobile network adopts a single-point access mode, and each short message center operates independently in a mobile communication network (such as a GSM network). Since the number of users supported by each access point is different, the load of each short message node is not balanced. At the same time, the independent short message center has no disaster recovery feature. Once a problem occurs in a certain node, all users in the short message center will be unable to send short messages.

[0003] For example, in the current GSM network, the short message center, as a service point with independent functions, accesses the PLMN (Public Land Mobile Network, Public Land Mobile Network) network through LSTP (Signaling Access Point). Each short message system is configured with one or several (if there are multiple short message ...
