Fig. 1 is the method flow schematic diagram of first embodiment of the invention, comprising:
Step 11: terminal, after switching completes, rebuilds the passage for sending note, and the described passage for sending note is released in handoff procedure;
Example is switched to 2G, this terminal can be specially travelling carriage (MobileStation, MS), MS can with access network control equipment, as base station controller (BaseStationController, BSC) rebuilds this for sending the passage of note.This passage being used for sending note can be specially Service Access Point Identifier (ServiceAccessPointIdentifier, SAPI) 3 passage.Wherein, in 2G communication, in order to realize the transmission of note, need first to set up SAPI3 passage.And in handoff procedure, this SAPI3 passage can be released.
Step 12: the described passage for send note of terminal by rebuilding, retransmits the note of buffer memory in handoff procedure.
Such as, TPDU message retransmission note is adopted by SAPI3 passage.
Especially, before above-mentioned switching specifically can occur in terminal transmission TPDU message.
Because terminal rebuilds the passage for sending note after the completion of the handover in the present embodiment, can improve after switching and sending the success rate of note, avoid invalid transmission and return the notice of short message sending failure.
Fig. 2 is the method flow schematic diagram of second embodiment of the invention, and the present embodiment switches with 2G, and terminal is example before sending TPDU message.See Fig. 2, the present embodiment comprises:
Regular traffic before step 21:MS switches, comprises short message service in this regular traffic.
Particularly, see Fig. 2, base station (BaseTransceiverStation, BTS) _ A, BSC_A, mobile switching centre (MobileSwitchingCentre, MSC) _ A are the network equipment before switching.Before the handover, MS and these network equipments carry out alternately, wherein, comprising and setting up SAPI3 passage, specifically can see latter two signaling of this step in Fig. 2.
Step 22:MS receives the switching command message (HANDOCMD) that MSC_A sends, and switches.
See Fig. 2, in this process, SAPI3 passage can be discharged according to existing protocol, such as, Suspend (sapi=0) Localrel (sapi=3) in Fig. 2.
In addition, in handoff procedure, MS also carries out the buffer memory of note.
Step 23:MS knows that switching completes after receiving the handoff completion message of MSC_B transmission.
Wherein, BTS_B, BSC_B, MSC_B are the network equipment after switching.
Step 24:MS initiates the reconstruction of SAPI3 passage.
Wherein, see Fig. 2, this step can specifically comprise:
MS sends SABM (SAPI=3) to BTS_B, and BTS_B sends ESTIND (SAPI=3) to BSC_B; BTS_B returns UA (SAPI=3) to MS.
Step 25:MS sends the note of buffer memory in handoff procedure by the SAPI3 passage rebuild.
Wherein, the note of repeating transmission can be carried at TPDU message see Fig. 2, MS, as sent to MSC_B in CP-DATA message, wherein, the passage between MS and BSC_B can adopt the SAPI3 passage of reconstruction, and the passage of BSC_B and follow-up equipment can adopt the passage usually adopted in prior art.
Afterwards, sms center replys SM-RP layer acknowledge message.
Wherein, see Fig. 2, this step can comprise sms center to MS return data (CP-DATA).
Be understandable that, specifically can also comprise other signalings in above-mentioned interaction flow, these other signalings with reference to prior art, can repeat no more in the embodiment of the present invention.
Because in handoff procedure, SAPI3 passage can be released, if do not rebuild SAPI3 passage after switching completes, even if MS retransmits note, this repeating transmission note also can not send successfully, causes invalid transmission.And the present embodiment rebuilds SAPI3 passage by terminal after switching completes, the SAPI3 passage of this reconstruction can be adopted to send note, improve the transmission success rate of note.
