Problems solved by technology

[0009] However, there is a problem with this method. For some densely populated areas, a large part of the SMS service may only occur between local users. If implemented according to the existing method, the SMS will always pass through the core network, which will increase The burden of the core network

Embodiment 1

[0036] Such as Figure 4 As shown, the method provided for an embodiment of the present invention includes the following steps:

[0037] S411. The BSS receives the short message sent by the first MS.

[0038] The first MS may use the existing technology to send the short message, for example, use the CP-DATA message to send the short message, and the CP-DATA includes the identifier of the receiver. For the convenience of expression, it is called the second MS here.

[0039] S415, if the first MS and the second MS are local users of the BSS, the BSS locally forwards the short message to the second MS.

[0040] In this step, if both the first MS and the second MS are local users in the BSS, the BSS may directly forward the short message to the second MS via the BSS without going through the core network.

[0041] The BSS local forwarding here refers to direct forwarding within the BSS without going through the core network. Three examples are given here, and these three examp...

Embodiment 2

[0087] See Figure 6 , Figure 6 Combined with the GSM system, a flow diagram of the method for sending and receiving short messages between two MSs under the same BTS is given.

[0088] In this embodiment, both MS A and MS B reside on the same BTS, and both are local users. Figure 6 The flow chart shown is a flow chart of MS A sending a short message to MS B.

[0089] Wherein steps S701-S705 are the phases in which MS A accesses the BTS. At this stage, MS A can access the BTS in an existing way.

[0090] S701, MS A sends a channel request message Channel Request to the BTS on a random access channel (RACH, Random Access CHannel);

[0091] S702-S705, for channel activation and channel activation response, after the BSC allocates the corresponding channel for MS A successfully, it notifies MS A of the dedicated channel (SDCCH, SDCCH, Stand-Alone Dedicated Control Channel).

[0092]S706 Subsequently, MS A will send a layer 3 message—CM Service Request on the SDCCH allocat...

Embodiment 3

[0140] See Figure 7 , Figure 7 A flow diagram of a method for sending and receiving short messages between MSs belonging to different BTSs is given.

[0141] Among them, MS A resides in BTS 1, and MS B resides in BTS 2. Both MS A and MS B are local users. If MS A needs to send short messages to MS B, MS A needs to access BTS 1 first to obtain the dedicated channel assigned by BTS 1. For the process of MS A accessing BTS 1, refer to Figure 6 The implementation of S701-S705 shown will not be repeated here.

[0142] Steps S806-S812, the process of requesting SMS service for MS, can refer to Figure 6 The implementation of S706-S713 shown will not be repeated here.

[0143] S813 MS A sends a CP-DATA message to BTS 1, and the message contains the content of the short message. After receiving the message, BTS1 can analyze the identity of the receiver MS B.

[0144] According to the analyzed identification of MS B, it is judged whether MS B is a local user, if so, proceed to ...

Abstract

The embodiment of the invention provides a short message sending method, a short message service device and a substation subsystem. The method comprises the following steps of: receiving a short message which is sent to the substation subsystem by a first mobile station (MS), wherein the receiving party of the short message is a second MS; and locally transferring the short message to the second MS by the substation subsystem if the first MS and the second MS are local users of the substation subsystem. The method provided by the embodiment of the invention can achieve short message services among local users without using a core network and lighten the load of the core network.

Description

technical field [0001] The invention relates to the communication field, in particular to a short message sending method, a short message service device and a base station subsystem. Background technique [0002] GSM (Global System for Mobile Communications, Global System for Mobile Communications) GSM is a digital mobile phone system widely used in Europe and other parts of the world. [0003] Such as figure 1 Shown is a schematic diagram of a GSM network structure in the prior art, including: a mobile station (MS, Mobile Station), a base station subsystem (BSS, Base Station Sub-system) and a network subsystem (NSS, Network SubSustem). The base station subsystem (BSS) includes a base station (BTS, Base Transceiver Station) and a base station controller (BSC, Base Station Controller); the core network (NSS) includes a mobile switching center (MSC, Mobile Switching Center) and an operation and maintenance center (OMC, Operation Operation & Maintenance Center), Home Location...
