Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the embodiment of the invention is described in detail below in conjunction with accompanying drawing.
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), GPRS (GPRS, General Packet Radio Service), Long Term Evolution (LTE, Long Term Evolution) etc.
See also Fig. 1, it is the flow chart of an embodiment of the transfer approach of a kind of business datum of the present invention, describes from the angle of BSC (Base Station Controller, base station controller).
101:BSC inserts request according to the channel that terminal sends, and is described terminal distribution access-in resource on PDTCH.
Described BSC inserts request according to the channel that terminal sends, and comprises for described terminal distribution access-in resource on PDTCH: the channel that the BSC receiving terminal sends inserts request, and described channel inserts the type that the request indication inserts; When BSC identifies access style and is the M2M type, be that one of described terminal distribution inserts piece on PDTCH.
For example, terminal inserts request by the base station to the BSC transmitting channel, inserts at channel and identifies the type that access is arranged in the request, and the type of access can be represented by inserting cause value.When the type that inserts is the M2M type, as, when intelligent meter data recording was professional, BSC was that one of this terminal distribution inserts piece on PDTCH
102:BSC receives the business datum that described terminal sends by the access-in resource that distributes.
103:BSC initiates the USSD business to core net, gives core net with business and data in the USSD business.
Preferably, described BSC initiates the USSD business to core net, and in the USSD business business datum is passed through core net and comprise: BSC carries out the USSD business to core network requests; BSC receive that core net sends accept message after, send registration message to core net, carry business datum in the described registration message; BSC receives core net and finishes message, the described response message of having carried application layer in the message of finishing what described business datum is received the back sends.
For example, obtained the business datum of terminal transmission as BSC after, the further pseudo-terminal of BSC, send Complete Layer 3 message by MSC to core-network side, inform core net initiation USSD business, if core net is accepted the request of BSC, promptly send CM Service Accept message to BSC, the USSD business is about to carry out.The BSC pseudo-terminal sends registration message to MSC, carries business datum in registration message.Because the BSC pseudo-terminal also sends business datum in the USSD business, therefore, for MSC, similarly be to receive from terminal, that is, BSC has realized service message is passed through MSC.MSC receives business datum frame by frame, after MSC is received all business datums, send Release Complete message to BSC, carry the response message of application layer in Release Complete message, BSC knows that business datum is all received by core net after receiving this message.
Further preferred, in order to realize collision detection, described method also comprises: after being described terminal distribution access-in resource, the interim identification code TMSI that the BSC receiving terminal sends by the access-in resource that distributes, the TMSI of described terminal is sent to described terminal, so that described terminal is carried out collision detection, then after collision detection is passed through, BSC initiates the USSD business to core net, in the USSD business business datum is passed through core net.
Need to prove, whether consistent collision detection be TMSI that terminal relatively receives and the TMSI of self process, terminal can adopt any collision detection method of the prior art to carry out collision detection, and the embodiment of the invention does not limit the specific implementation method of collision detection.
For example, BSC is for after initiating to insert the terminal distribution access-in resource of request, initiation inserts the terminal of request when the access-in resource transmission business datum of passing through to distribute is to BSC, also report TMSI to give BSC, BSC returns TMSI again and gives this terminal, like this, the terminal that initiate to insert just knows that own channel inserts asks to have been received by network, and the resource of network allocation also distribute to oneself really.
In addition, preferred, when the BSC pseudo-terminal, after initiating the USSD business to core net, in the USSD business, send business datum to MSC before, initiate once authentication by MSC to terminal, after treating that MSC passes through the authentication of terminal, BSC sends business datum to MSC in the USSD business.At this moment, described method also comprises: BSC is after initiating the USSD business to core net, in the USSD business, send business datum to core net before, BSC sends to described terminal with the authentication request that core net sends by PDTCH, terminal is sent to core net by the authentication responses that PDTCH sends, wherein, before initiating the USSD business to core net, BSC is the TBF resource in the terminal distribution uplink downlink; Then described BSC passes through core net with business datum in the USSD business: after authentication was passed through, BSC passed through core net with business datum in the USSD business.
For example, before MSC initiated the USSD business, BSC was the TBF resource in the terminal distribution uplink downlink of request access at the BSC pseudo-terminal.Like this, on the PDTCH channel, terminal receives and sends data block on the TBF of appointment resource.At BSC after MSC initiates the USSD business, in the USSD business, send business datum to MSC before, MSC sends authentication request to BSC, BSC inserts this authentication request by the PDTCH request of being transmitted to terminal, the terminal that this request inserts sends to BSC by PDTCH with authentication responses, BSC is transmitted to MSC with this authentication responses, and after MSC passed through the authentication of terminal, BSC passed through MSC with business datum in the USSD business.
Preferably, in order to save the TBF resource, after the business datum transmission finishes, BSC can also come the requesting terminal to discharge the TBF resource by send release TBF resource request to terminal, after treating that terminal has discharged the TBF resource, report that by the message that finishes to BSC transmission TBF release resource BSC has discharged the TBF resource.Simultaneously, because the BSC pseudo-terminal is initiated the USSD business to MSC, therefore, for MSC, it does not also know that resource is released, and it only sees a common USSD business.After MSC has issued Rlease Complete message, if it is mutual that MSC confirms to no longer include between " terminal " (this terminal is simulated by BSC) and the core net, then MSC can ask BSS (base station sub-system) internal resource and the interface-free resources of " terminal " (this terminal is simulated by BSC) release busy, because terminal has discharged resource, therefore, BSC directly replys.
As can be seen from the above-described embodiment, terminal sends to BSC by PDTCH with business datum, and the BSC pseudo-terminal further passes through MSC with business datum in the USSD business.Compare with SDCCH, because the data head of PDTCH is less, can not take a large amount of network overheads, therefore the dedicated channel that neither monopolize, can be avoided the network resource consumption brought owing to bigger data head, and can improve service efficiency.Simultaneously, the flow process of USSD business is simple, also can not bring bigger signaling consumption.Finally, the network overhead in the time of can saving transmit traffic data, and then save Internet resources.
