Example Embodiment

[0035] Example 1

[0036] Such as Figure 4 As shown, the method provided by 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 can use the existing technology to send the short message, for example, the CP-DATA message is used to send the short message. The CP-DATA includes the identifier of the receiver. For ease of presentation, it is referred to as 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 the first MS and the second MS are both local users in the BSS, the BSS may directly forward the short message via the BSS to the second MS without passing through the core network.

[0041] The BSS local forwarding here refers to forwarding directly within the BSS without going through the core network. Here are three examples. None of these three...

[0086] Example 2

[0087] See Image 6 , Image 6 Combined with the GSM system, a schematic flow diagram of the method for two MSs under the same BTS to send and receive short messages is given.

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

[0089] Among them, steps S701-S705 are the stages of MS A accessing the BTS. At this stage, MS A can access the BTS in the existing way.

[0090] S701, MS A will send a channel request message Channel Request to 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 to MS A successfully, it informs MS A of the dedicated channel (SDCCH, SDCCH, Stand-Alone Dedicated Control Channel).

[0092] In S706, MS A will then send a layer three message-CM Service Request on the allocated SDCCH...

Example Embodiment

[0139] Example 3

[0140] See Figure 7 , Figure 7 The flow diagram of the 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 first needs to access BTS 1 to obtain a dedicated channel assigned by BTS 1. For the process of MS A accessing BTS 1, please refer to Image 6 The implementation of S701-S705 shown is not repeated here.

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

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

[0144] According to the parsed identification of MS B, it is determined whether MS B is a local user, and if it is, step S814 is cont...

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...
