Embodiment

In below describing,, understand the present invention so that cut thoroughly in order to illustrate rather than, to have proposed the detail such as particular system structure, interface, technology in order to limit.Yet, not it will be clear to one skilled in the art that in having other embodiment of these details and can realize the present invention yet.In other situation, omit detailed description, in order to avoid unnecessary details hinders description of the invention to well-known device, circuit and method.

In the present embodiment, travelling carriage can communicate through base station sub-system and one or more core net, travelling carriage can be mobile phone (or being called " honeycomb " phone), or has a computer of portable terminal, for example, can be portable, pocket, hand-hold type, mobile device built-in computer or vehicle-mounted etc.

Technical scheme of the present invention, can be applied to various communication systems, for example: GSM, code division multiple access (CDMA, Code Division Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access Wireless) etc., LTE systems such as (LTE, LongTerm Evolution).But for the convenience of describing, following embodiment mainly is that example is elaborated with GSM.

Embodiment 1

As shown in Figure 4, the method for one embodiment of the invention provide comprises the steps:

S411, BSS receive the note that a MS sends.

The one MS can adopt prior art to send note, for example adopts CP-DATA message to send note, comprises recipient's sign among the CP-DATA, for explaining conveniently, is called the 2nd MS here.

S415, if a MS and the 2nd MS are the local user of this BSS, local this note of transmitting of BSS is given the 2nd MS.

In this step, if the local user that a MS and the 2nd MS are at this BSS, then BSS can be without core net, but directly with this note, is transmitted to the 2nd MS through BSS this locality.

The BSS here is local to be transmitted, and refers to without core net, directly in the inner forwarding of BSS.Here provided 3 kinds of examples, these 3 kinds of examples do not need through the core net forwarding short message: 1, if a MS and the 2nd MS all reside in same base station, then directly be transmitted to the 2nd MS, and do not need to transmit this note through BSC or core net by this base station; 2, if a MS resides in different base stations with the 2nd MS, then directly give another base station with this note by base station controller, when base station controller is transmitted, do not need to transmit through core net; 3, between base station and base station, set up a connection, directly note is transmitted to another base station by a base station, another base station sends to note the 2nd MS again, and here, the forwarding of note does not need through core net yet.

The local user of BSS is meant the user in the BSS registration.For example, can preserve user's log-on message in the BSS kind, if the information of MS among this log-on message, then is the local user of BSS.

Be understandable that BSS can adopt prior art and the 2nd MS foundation to be used to receive and dispatch the link of note, and then transmits this note to the 2nd MS.

For the short message service between the local user who belongs to same BSS, BSS can pass through local forwarding short message, thereby transmits this note without core net, thereby has reduced the mutual of BSS and core net, has alleviated the burden of core net, has saved transfer resource.

Further, the method that present embodiment provides can also be responsible for judging whether to receive the short message service that a MS initiates, with the signaling process of further minimizing and core net by BSS.See also Fig. 5, comprise the steps:

S401 BSS receives the business request information that a MS sends.

For example, this business request information can be CM Service Request, and the type of request service is a short message service, and carries relevant parameter.

In gsm system, MS can adopt prior art to insert BSS, for example, channel request, channel activates, and channel activates response, assignment immediately, be MS assignment dedicated channel, MS can send to BSS with CM Service Request by Asynchronous Balanced Mode SABM (SABM, Set AsynchronousBalanced Mode) frame is set in the dedicated channel of assignment, after BSS receives this request message, can reply a unnumbered acknowledge UA frame.

And in the WCDMA system, base station sub-system is by Node B and (RNC, Radio NetworkControl) forms, MS can and RNC (RNC, Radio Network Control) set up RRC (RRC, Radio Resource Control) and connect after, by the direct-sending message (DirectTransfer of layer 3, DT), send CM Service Request to base station sub-system.

S403 BSS judges whether a MS is the local user.

BSS can identify according to the local user of MS and judge whether a MS is the local user.If BSS does not have local user's sign of a MS, then can obtain this local user's sign by identity request message.

As an example, this local user's sign can be IMSI, also can be the number of a MS.

For example, BSS searches this user's log-on message according to the international mobile subscriber identity IMSI (IMSI, InternationalMobile Subscriber Identity) of this MS, if this user is registered as the local user in BSS, then this MS is the local user.If BSS does not have the IMSI of a MS, then BSS can send identity request message (Identiy request) to a MS, the one MS replys identity request response message (Identity Response), in this identity request response message, carries the IMSI information of a MS.

If a MS is the local user, then continue execution in step 405.

S405BSS sends the professional message that receives to a MS.

If BSS, judges that a MS can initiate short message service according to the log-on message of a MS, then BSS directly sends the professional message (CM Service Accept) that receives to a MS.

In this step, judge by BSS whether a MS can initiate short message service, but not judge by core net whether a MS can initiate short message service, thereby can further reduce the signaling process of BSS and core net.

After receiving business request information, can set up the link that is used to receive and dispatch note between a MS and the BSS.For example, after a MS receives CM Service Accept message, send SABM (SAPI=3) frame to BSS, BSS replys the UA frame.After receiving the UA frame, a MS just can send note to BSS.

Further, the method that present embodiment provides can also be judged whether to receive the 2nd MS is initiated short message service by BSS, between step S411 and step S413, can also comprise the steps:

Step S412 BSS judges whether the 2nd MS is the local user.

For example, BSS can parse the recipient's of note sign (i.e. the sign of the 2nd MS), according to the sign of the 2nd MS according to the CP-DATA of step S411 reception from CP-DATA, whether search the log-on message to identifying among the BSS, be the local user to judge the 2nd MS.

If the 2nd MS is the local user, then continue execution in step 413.

S413, BSS notify the 2nd MS to insert.

BSS can judge whether the 2nd MS can carry out short message service according to the 2nd MS log-on message, if can BSS just can notify the 2nd MS to insert, and need not affirmation with core net, further reduces and the Signalling exchange of core net.

For example, BSS can send beep-page message Paging Request to the 2nd MS, after the 2nd MS receives beep-page message, inserts according to prior art.Promptly pass through channel request, channel activates, and channel activates response, and after the assignment, execution in step S414 is no longer through core net authentication and safe mode etc. immediately.

S414BSS and the 2nd MS set up and are used to receive and dispatch the link of note.

For example, BSS sends SABM (SAPI=3) frame to the 2nd MS, and the 2nd MS replys after the UA frame, and then BSS just can send note to the 2nd MS.

After receiving the UA frame of the 2nd MS answer, continue execution in step S415.

For example, BSS sends to core net with the CM Service Request message that a MS sends, receive the CM Service Accept message that core net is replied, the CP-DATA message that a MS reports before inciting somebody to action again sends to core net, and follow-up carries out according to existing note flow process.

Further, the method that present embodiment provides, if BSS judges the non-local user of a MS among the S403, if perhaps among the step S412, BSS judges the non-local user of the 2nd MS, then the method that provides of present embodiment, further execution in step S404.

S404 BSS sends to core net with business request information.

For example, BSS gives core net according to prior art with CM Service Request forwards, judges whether to receive the business request information that a MS sends by core net.If core net allows a MS to send note, then will send the professional message that receives to BSS.

If core net has received this business request information, then the method that provides of present embodiment can further comprise step S418.

S418 BSS receives the business reception message that core net sends.

BSS receives after this message, if a MS is the local user, then BSS can transmit the professional message that receives to a MS again; If a MS is non-local user, then BSS need transmit the professional message that receives to a MS.

As an example, this message can be CM Service Accept message.

S419 BSS transmits the note that a MS sends to core net.

Follow-up flow process is consistent with prior art, after BSS receives the note of a MS, transmits to core net, is responsible for transmitting this note to the 2nd MS by core net.

Further, the method that present embodiment provides can also comprise:

Step S417 BSS charges (Fig. 2 does not show) to the short message service of a MS.

For example, after execution in step S415, perhaps execution in step S415 the time, the short message service of a MS is chargeed.This charge information can be after business be finished or periodically upload to the charge system of core net.

The method that present embodiment provides can be applied to the big and mobile not high zone of the density of population, and in these zones, the short message service between most MS may occur in the overlay area of same base station.

Therefore, the method that present embodiment provides, if the MS of transmitting-receiving note is positioned under the same base station, then can be by this base station execution in step S411, S415, further to raise the efficiency.

Further, step S405 also can be carried out by this same base station (carrying out the base station of S411, S415).Under some scenes, as rural area and remote districts, base station and base station controller distance is far away, sends the professional message that receives by the base station, can further raise the efficiency, and can reduce mutual between base station and the base station controller, saves transfer resource.

Further, the method that present embodiment provides for local user's short message service, can directly be transmitted in this locality by the base station of base station sub-system, without core net, also without base station controller.Therefore, an accessory module can be set on the base station, and this accessory module has the function of base station controller, can receive and handle the signaling of base station by anolog base station controller, make the base station can break away from base station controller and work on, by the note between this locality forwarding local user.Realize that so even if base station and base station controller are out of touch, the communication service between the local user can not paralysed, provide guarantee for the communication in the area of remote, poor transmission.

Embodiment 2

See also Fig. 6, Fig. 6 has provided the method flow schematic diagram of two MS transmitting-receiving notes under the same BTS in conjunction with gsm system.

In the present embodiment, MS A and MS B reside in same BTS, and are the local user.Flow chart shown in Figure 6 is the flow chart of MS A to MS B transmission note.

Wherein step S701-S705 inserts the stage of BTS for MS A.The existing mode that this stage MS A can adopt inserts BTS.

S701, MS A will be in Random Access Channel (RACH, Random Access CHannel) to BTS channel request message Channel Request;

S702-S705, for channel activates, channel activates response, BSC is for after MS A the distributes corresponding channel success, passing through immediately in access grant channel, assignment messages (IMM ASS Command) notice MS A is the dedicated channel (SDCCH, Stand-Alone Dedicated Control Channel) of its distribution.

S706 MS A subsequently will by the SABM frame, send layer three message-CM Service Request on the SDCCH that is its distribution, this business request information is used to ask short message service.

S707 BTS replys a UA frame to MS A.

S708-S709 is the optional stage, if BTS has the IMSI information of MS A, then need not to carry out S708 and S709, if for example MS A is in speech phase, just need not to obtain the IMSI information of MS A; If BTS does not have the IMSI information of MS A, then can execution in step S708-S709.

S708 BTS sends Identiy Request message to MS A; S709 after MS A receives, reports an Identity Response message, the IMSI information of carrying MS A.

If S710 BTS, judges that MS A is the local user according to the IMSI information of MS A, then can directly send CM Service Accept message to MS A.

In the present embodiment, can preserve local user's log-on message in advance among the BTS, BTS judges according to log-on message whether MS A is the local user, and whether can carry out short message service, if of course, just directly send CM Service Accept message to MS A.

Contrast flow process shown in Figure 2, flow process shown in Figure 2 in the short message service request that judges whether to receive MS A, needs through step (7)-(11), through BSC and these two nodes of MSC.And the method that present embodiment provides, BTS need not and the mutual signaling of core net, can directly judge whether to receive the short message service request of MS A, therefore can simplify signaling process, also can reduce the Signalling exchange of BTS and BSC according to the log-on message of local user MS A.

S711, MS A sends SABM (SAPI=3) frame to BTS.

S712 BTS sends the UA frame to MS A.

S713 MS A sends CP-DATA to BTS, and CP-DATA carries the content of note.

After BTS receives, can resolve CP-DATA, obtain the recipient's (MS B) of note sign, judge according to sign whether MS B is the local user.If be the local user, then continue execution in step 714.

Otherwise, if user B is not the local user of BTS, BTS issues BSC with CM Service Request so, send to MSC then, receive the CM Service Accept message that MSC replys, the CP-DATA message that user A reports before inciting somebody to action again sends to MSC through BSC, and is follow-up according to flow performing shown in Figure 2.

S714 BTS sends Local SMS Indication to BSC.

Local SMS indication message is used to notify BSC to keep Radio Resource for MS A.For example, can carry the sign of the channel of distributing to MS A in this message, BSC is left the wireless channel that MS A distributes with notice, no longer these wireless channels is given other MS.

S715 BTS sends paging information Paging Request to MS B.

S716-S720 is the process of MS B access BTS, and its flow process is same as the process (S701-S705) that MS A inserts BTS, repeats no more.

S721 MS B sends the SABM frame by the channel of S720 assignment to BTS, and this SABM frame carries paging corresponding message (Paging Response).

S722 is after BTS receives the SABM frame of MS B, sends the UA frame to MS B.

After S723 executed back S722, BTS sent SABM (SAPI=3) frame to MS B.

Here, BTS need not to transmit message to core net, contrasts note called flow shown in Figure 3 as can be known, and the method that present embodiment provides does not need and the mutual signaling of core net, can simplify flow process.

S724 BTS receives the UA frame that MS B sends.

After S725 BTS receives the UA frame of MS B, send Local SMS Inidication to BSC, notice BSC is preserved for the Radio Resource of short message service for MS B.

S726 BTS transmits the CP-DATA that MS A sends to MS B, and CP-DATA has carried the content of note.

S727 BTS receives the SMS confirmation message CP ACK that MS B sends.

S728 BTS is to MS A forwarding short message acknowledge message CP ACK.

Step S726-S728 is that BTS transmits the note that MS A sends to MS B by this locality, and gives CP ACK with the SMS confirmation forwards that MS B receives.

Contrast flow process shown in Figure 2 as can be known,, by local forwarding short message, do not need to pass through the core net forwarding short message just like that, thereby can alleviate the burden of core net as prior art by BTS at step S726-step S728.

Be understandable that BTS also can locally transmit the note that MS B sends to MS A, mode and S726-S728 are similar, all without core net.

After note between MS A and MS B sends and finishes, can execution in step S729.

S729 MS A sends Disconnect message to BTS.

After BTS receives Disconnect message, just can directly carry out S730, initiate to discharge flow process, and need not Disconnect message is passed through to core net.

S730 BTS sends Release message to MS A.

S731 MS A sends Release Compelete message to BTS.

S732 BTS sends Disconnect message to MS B.

Directly produce Disconnect message by BTS, and send to MS B.

S733 MS B sends Release message to BTS.

S734 BTS sends Release Complete message to MS B.

S735 BTS sends Local Channel Release message to BSC.

Notice BSC is released to the Radio Resource that MS A keeps.

S736 BTS sends Channel Release message to MS A, the logic channel of notice MS A release busy.

S737 BTS sends Local Channel Release message to BSC, and notice BSC is released to the Radio Resource that MSB keeps.

S738 BTS sends Channel Release message to MS B, the logic channel of notice MS B release busy.

S739-S752 is deexcitation channel and release physical channels, and the signaling that is adopted is consistent with prior art, but in the process of removing the short message service connection, BTS and BSC need not and the mutual signaling of core net.

By above-mentioned description as can be known, from step S729-S752, in the process of removing short message service, BTS and BSC need not and the mutual signaling of core net, can alleviate the burden of core net; And BTS need be by BSC in the transparent transmission signaling yet, thereby has reduced the Signalling exchange between BTS and the BSC yet.

Be understandable that, the message in the above-mentioned steps, except that Local SMS Indication message, remaining message all can adopt the form of prior art definition, and only the transmission main body of some message changes.For example, the format and content of the Channel Reqeust message of S701, can be consistent with the Channel REQ of existing procedure among Fig. 2 (1), difference is, in the method that present embodiment provides, if MS A is the local user, then this message can directly be handled by BTS, and no longer pass through BSC; For another example, the Channel Release message of S736 can be consistent with the ChannelREL message in the flow process (22) of Fig. 2, and difference is that in the method that present embodiment provides, this message sends to MS A by BTS.

The method that present embodiment provides has reduced mutual between base station sub-system and the core net, has alleviated the burden of core net; And the Signalling exchange of BTS and BSC also significantly reduces, and has simplified signaling process, has saved the transfer resource between BTS and the BSC.

The method that present embodiment provides is particularly useful for independently population concentration zone of remote countryside or other, has realized using transfer resource still less, satisfies the demand of transmitting-receiving note between the local user.

Embodiment 3

See also Fig. 7, Fig. 7 has provided the method flow schematic diagram of transmitting-receiving note between the MS that belongs to different B TS.

Wherein, MS A resides in BTS 1, and MS B resides in BTS 2.MS A and MS B are the local user, if MS A need send note to MS B, then MS A at first needs to insert BTS 1, obtains the dedicated channel of BTS 1 assignment.MS A inserts the process of BTS 1, can realize with reference to S701-S705 shown in Figure 6, repeats no more.

Step S806-S812 is the process of MS request short message service, can realize with reference to S706-S713 shown in Figure 6, repeats no more.

S813 MS A sends CP-DATA message to BTS 1, and this message comprises short message content.After BTS1 receives this message, can resolve the sign of recipient MS B.

The sign of the MS B that obtains according to parsing judges whether MS B is the local user, if, then continue execution in step S814, send Local SMS indication to BSC, notice BSC is preserved for receiving and dispatching the Radio Resource of note for MS A.If not, then the CM Service request forwards that S806 is received is given core net, is judged whether to receive the service request (Fig. 7 does not show) of MS A by core net.

Because MS B does not reside in BTS 1, then BTS 1 need obtain the actual resident BTS of MS B.For example, BTS 1 can obtain the log-on message of MSB according to the sign of resolving the MS B that obtains from the local service module, obtain the BTS of MS B registration according to log-on message; Perhaps, BTS 1 can be to the base station at all neighbor cell places mass-sending Query Information, to obtain the actual resident BTS of MS B.

In flow process shown in Figure 7, at step S815, BTS 1 is used for MS B is initiated paging to all BTS mass-sending Pagingrequest notes.After BTS 2 receives this message, carry out S816, send Paging request message by paging channel.

After receiving Paging request message, MS B initiates access process, to insert BTS 2.This access process can be similar with the access process of MS A, repeats no more.

Step S821-S825 receives flow process for service:

S821:MS B sends the SABM frame to BTS 2, and this frame carries Paging Response message; BTS 2 sends a UA frame to MS B after receiving.

S824 BTS2 sends SABM (SAPI=3) frame, and MS B replys the UA frame, sets up to be used to receive and dispatch the link of note; Simultaneously, BTS2 sends Local SMS Indication to BSC, and notice BSC is left MS B assigned radio resource.

S827 BTS2 sends Paging Response message to BTS 1, resides in BTS 2 with notice BTS 1 this MS B; After receiving this message, BTS 1 is transmitted to BTS 2 with CP-DATA, and BTS sends to CP-DATA MS A again.

Note enters the release flow process after sending and finishing, to discharge assigned radio resource.The flow process of distributing can be with reference to the release flow process of figure 6, and just BTS1 is released to MS A resources reserved; And BTS2 is released to the Radio Resource that MS B keeps.

The method that present embodiment provides, reduced and core net between mutual, alleviated the burden of core net; And the Signalling exchange of BTS and BSC also significantly reduces, and has simplified signaling process, has saved the transfer resource between BTS and the BSC.

Embodiment 4

See also Fig. 8, the method flow schematic diagram of another short message service that Fig. 8 provides for present embodiment.In the present embodiment, MS A and MS B all are in talking state.

This moment, MS A was in talking state, thereby BTS can know the IMSI of MS A, knew just whether MS A is the local user.

If S901 MS A is the local user, MS A sends CM Service Request message to the base station by SACCH (SACCH, SlowAssociated Control Channel) channel.

CM Service Accept message is replied in S902, base station.

S903 MS A receives that the back sends the SABM frame that has SAPI=3.

The UA frame is replied in the S904 base station.

S905 MS A sends CP-DATA message to the base station, and the base station parses the sign of note called MS B, and the base station can judge whether MS B is local user under the base station.

S906 MS B also is in talking state, if MS B also is the local user, the base station sends by the SACCH channel and has the SABM frame of SAPI=3 to MS B so.

S907 MS B replys the UA frame.

The S908 base station sends to CP-DATA and receives MS B.

S909 MS B replys response message CP ACK and gives the base station, and the base station is transmitted to transmit leg MS A.

Be understandable that if MS B is not in talking state, then the base station can be adopted and is similar to S715-S725 shown in Figure 6, makes MS B access base station,, set up the link that carries out short message service for MS B keeps Radio Resource.

Perhaps, if MS A is not in talking state, then can adopt similar S701-S714 shown in Figure 6, access base station for MS A keeps Radio Resource, is set up the link that is used for short message service.

Embodiment 5

See also Fig. 9, Fig. 9 is arranged in base station sub-system for a kind of short message service device that present embodiment provides, and comprising: first transceiver module, 51, the second transceiver modules 52 and local service module 53.

First transceiver module 51 is used to receive the note that first mobile station MS sends, and the recipient of note is the 2nd MS;

Local service module 53, if be used for a MS and the 2nd MS is the local user of base station sub-system, the note that a MS is sent is transmitted to second transceiver module by this locality;

Second transceiver module 52 is used for the note to the 2nd MS transmission local service module forwards.

This short message service device is positioned among the base station sub-system, can be arranged in a base station, also can be arranged in a plurality of base stations.A short message service device can be arranged in the base station sub-system, also a plurality of short message service devices can be arranged, as a short message service device is all arranged in each base station.

The local user is meant that local user's log-on message can be kept in the local service module 53 the user of BSS registration.

The short message service device that present embodiment provides can be used to carry out the method embodiment that the foregoing description provides.Transmit this locality here, is exactly directly to be transmitted in BSS inside by local service module 53, and need not through core net, thereby can alleviate the burden of core net.

As another example, if local service module 53 is judged the non-local user of a MS, then local service module 53 can be transmitted to core net with this business request information.

As another example, this local service module 53 can comprise local user's log-on message, comprises local user's information of MS in the log-on message, can identify according to the local user of MS to judge whether a MS is the local user.This local user's sign can be IMSI, the perhaps number of MS.For example, whether the local service module is searched MS by IMSI in local user's the log-on message is local user's information, if there is not the IMSI information of a MS in the local service module 53, local service module 53 can be obtained the IMSI information of MS by identity request message.

About first transceiver module,, can also receive the message of a MS except receiving the note of a MS.For example, after base station 1 received the Channel Request message of MS transmission, first transceiver module 51 was carried out the S702-S705 among the embodiment shown in Figure 7.After first transceiver module 51 was the MS assigned with dedicated channel, first transceiver module 51 can receive the message of a MS.

For example, after first transceiver module 51 receives CM Service Request message, be transmitted to local service module 53; The local service module can use flow process S708-S709 shown in Figure 7 to obtain the IMSI of a MS, and judges according to IMSI whether a MS is the local user; If local service module 53 judges that a MS is the local user, send CM ServiceAccept message to a MS by first transceiver module 51.

As another example, local service module 53 can also be used to handle the signaling in the step middle level three such as S714, S715, S732 of Fig. 7.

Be understandable that,, also can adopt similar scheme to realize for the system of other standard.As, for the WCDMA system,, preserve local user's log-on message by a PC, and the software module of operation core net, with processing layer 33 signaling relevant, realize the function of local service module 53 with core net; This PC is connected with Node B by maintenance channel, and Node B is transmitted to this PC with all signalings, is the communication service between the local user if PC judges communication service, and then PC directly handles by the core net software module of operation; If the communication service between the non-local user, then PC is transmitted to core net, handles according to existing procedure.Adopt this mode, can maximized minimizing to the change of code in the base station.

From foregoing description as can be known, local service module 53 can have the function of part core net, can handle some BSS need with the core net interactive signaling; Thereby, when local service module 53, receive after the signaling of

first transceiver module

51 or 52 forwardings of second transceiver module, can handle by the analog core net, thereby can reduce the Signalling exchange of BSS and core net, further alleviate the burden of core net.
