Embodiment 1

[0021] The short message system of this embodiment is equivalent to recomposing a plurality of short message systems into a larger network short message system, and its network diagram is for example figure 2 shown.

[0022] figure 2 The shown network short message system solution breaks the one-to-one correspondence between GIW and SMSC and GIW and LSTP in the traditional system. In the network short message system, GIW and SMSC are many-to-many concepts. GIW equipment and multiple short message centers are interconnected through a data network (that is, a packet switching network, generally referring to the internet or intranet connected through the TCP / IP protocol). The network short message center realizes disaster recovery between systems and load distribution of several short message systems. As shown in the figure, the system includes three (certainly also can be other numbers) short message gateway GIW and three short message centers SMSC, and each short message ga...

Embodiment 2

[0030] The second embodiment is further improved on the basis of the first embodiment, so that in addition to the advantages of disaster recovery, the network short message can also balance the load among multiple short message subsystems.

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 ...
