FIELD OF THE INVENTION

This application relates to the communication technology and in particular, to a method and device of transmitting short message.

BACKGROUND

Usually in VAS (Value Added Service), users need to be notified with notification of subscribed services which used to be in huge numbers; it increases the traffic between VAS system and SMSC (Short Message Switching Center). Similarly after sending each individual SUBMITSM, which is a PDU (Protocol Data Unit) of the short message, SMSC has to return its SUBMIT_SM_RESP, which is another PDU of the short message, to VAS system.

Currently even a small or medium scale advertising company needs to send advertisements to different subscribers with different content of SM (Short Message) notification.

In this embodiment, the SMSC may acquire the information of MSC from HLR (Home Location Register) by using SRI (Send Routing Information). However, it is not limited thereto, and particular implement way may be determined as actually required.

Step 204, the SMSC sends the contents of the short message to corresponding destination addresses.

In this embodiment, the SMSC may send each of the contents to a corresponding MSC according to the information of multiple destination addresses, such that the corresdonding MSC will send the content of the short message to the corresponding destination address.

Step 205, the SMSC receives a response message from the MSC;

Step 206, the SMSC sends the response message to the VAS system, such that the VAS system updates status according to the response message.

In this embodiment, the response message may be defined by a PDU named SUBMIT_MULTI_RESP, and the SUBMIT_MULTI_RESP may include several fields, such as: dest_addr_ton, dest_addr-npi, destinationaddr and errorstatuscode.

Where, destaddrton is used for indicating type of number for destination address; destaddrnpi is used for indicating numbering plan indicator for destination address; destinationaddr is used for indicating destination address of SME. error_status_code is used for indicating the success or failure of the transmitting short message.

Table 4 a definition of SUBMIT_MULTI_RESP type

As shown in table 4, there is a field of unsuccesssme. And unsuccess-sme may have fields as below.

Table 5 a structure of unsuccess sme

In this embodiment, one SUBMITMULTI will have its unique sequence number and with respect to same sequence number SMSC sends SUBMIT_MULTI_RESP to VAS System with above information on it, VAS will resend the SUBMIT_MULTI for only for failed SME information.

Figure 3 is an example showing a short message is submitted in the present application. As shown in Figure 3, there are four user equipments: sender A, B and receiver C, D.

For example, the reference mobile number may be: A-8095197563; B-8095197564; C-8095197565; D-8095197566. Here A, B, C and D are SME numbers.

As shown in Figure 3, the process may include:
301, VAS system frames the SUBMIT-MULTI message of senders A, B for corresponding destination C and D.

In this embodiment, the VAS system may send a short message to the SMSC. The PDU structure of the short message may be described as below:

As shown in table 6, there are two source addresses and two destination addresses. It is noted that the above example described as embodiments of this application. However, it is not limited thereto, and particular implement way may be determined as actually required.
302, SMSC sends SRI request for C to HLR.
303, SMSC sends SRI request for D to HLR.
304, HLR sends SRI response with MSC address as MSC1 for SRI Request of C.
305, HLR sends SRI response with MSC address as MSC1 for SRI Request of D.
306, SMSC sends MT (Mobile Terminated) request to MSC 1 of C.
307, SMSC sends MT request to MSC1 of D.

In this embodiment, SMSC may acquire the content of the short message according to source address. For example, the sender A corresponds to SM1
308, MSC1 tries to send SM1 to C (from sender A) as separate DELIVER SMs to C.
309, MSC1 sends SMSC MT Response as success for C.
310, MSC1 tries to send SM1 to D (from sender A) as separate DELIVER SMs to D.
311, MSC1 sends SMSC MT Response as success for D

As shown in Figure 3, the sender A may submit Short Message 1 (SM1) to SMSC to deliver to C and D. SMSC sends SUBMIT_MULTI_RESP to VAS for its successful submit to SMSC.

In this embodiment, for example, Command ID is 0x00000021 of SUBMIT_VIULTI, it used for SMSC to recognize it and for SUBMIT_SM as 0x00000004.

In case of the same content to be sent to different destinations then Initial_sm_length and Final_sm_length will be used to find out the short message content but in case of the same destination to be sent multiple times then need to have same destinations to be there in Dest_Address of SUBMIT_MULTI message.

In this embodiment, SMSC needs to support SUBMITMULTI using newly introduced IE (i.e. numberofsources, sourceaddresses and smlengthes).

Where, number_of_sources is the count of different source address (i.e. by default its value will be 1 and in case of multiple source address value will be changed and max value which is been supported as 255). sourceaddresses is a composite type which includes sourceaddrton, source_addr_npi and sourceaddr. sm_length_es is a composite type includes smlength (i.e. as a offset of SM content length for each destination address from corresponding source).

Furthermore, as shown in table 1, payload may be used in SUBMITMULTI to support the large size of SM content since shortmessage supports only 254 bytes. Currently for each SUMBIT_MULTI SM, multiple SRI and ACK is already been there and multiple different DLIVERSM are been sent as per different destination number.

It can be seen from the above embodiment that different source addresses and destination addresses are combined in a short message; such that there is less protocol overhead and performance is improved.
