Description
Technical field
The present invention relates to the Radio Access Network technical field, be meant a kind of method that realizes caller identification information transmission and demonstration (CID) business at wireless access network especially.
Background technology
Traditional caller identification information transmits and display business (CID), it is the business that provides towards fixing called phone, be meant on fixing called user terminal equipment display of calling number, calling subscriber's name, call out caller informations such as date, time, and store a kind of service item of consulting for the user.Show the schematic diagram that landline telephone is realized the CID business as Fig. 1, the LE that makes a start passes through interoffice signaling system----with caller identification information and sends receiving terminal switch (LE) to as the NO.7 signaling system, receiving terminal LE utilizes the time slot of carrying out ring for the first time and ring for the second time to the called subscriber, mode by baseband transmission on subscriber's line, promptly, send caller identification information to fixedly called user terminal equipment in the mode of Dual Tone Multifrequency or frequency shift keying (FSK).
(the PHS of individual radio system, Personal Handyphone System) Personal Handyphone System(PHS) that provides, be exchange, transmission and the number resource that in a local network scope, utilizes fixed network, and the terminal that the combining wireless access technology realizes possess limited ambulant fixed line communication service.PHS schematic network structure as shown in Figure 2, PHS comprises base station (BS), Radio Access Controller (RAC), PSTN network side LE at network side.Personal terminal (PS, Personal Station) inserts BS and RAC by air wireless interface, and RAC realizes Personal Handyphone System(PHS) by V5 interface access fixed network side LE.In RAC, virtual core network (VCN) module realizes the signaling controlled function, and signaling message stream is represented in the dotted line connection among the figure; Strengthen encoding and decoding speech (EVC) module and finish the speech business processing, receive the pcm stream that LE sends, be converted to the signal frame stream that air interface requires, speech business stream is represented in the solid line connection among the figure; Wherein, EVC sets up the voice traffic channel of EVC to LE under the control of VCN, transmits speech business stream.
The V5 interface is to aim at the development of user access networks and the LE that proposes and the interface between the Access Network.The audio call of personal terminal uses V5 PSTN agreement to connect at the V5 interface.At the V5 of standard interface----V5.1/V5.2 interface, cid information is to send from LE in the mode of Dual Tone Multifrequency or frequency shift keying (FSK) through voice traffic channel, but, in the PHS system, because user terminal no longer directly links to each other with LE, can't realize the CID business in the mode based on baseband transmission.Its reason is that present most PS does not handle the DTMF/FSK signal; On the other hand, LE must send the FSK/DTMF signal between the first time, ring for the second time, and the air wireless interface access is long settling time, be difficult in and find travelling carriage in the so short time and set up air traffic channel with it, make the terminal receiving course to cooperate with the LE number of sending out process coordinating.
In order to realize that LE can pass to personal terminal by wireless access network with cid information, at present the V5 agreement is expanded and revised, formed the V5+ agreement.The V5+ protocol modification cadenced ringing tone and two information units of pulse signal of PSTN agreement of V5 interface, make this two cell after the expansion can carry caller identification information.LE just can directly be carried at the caller cid information in cadenced ringing tone and two cells of pulse signal in the mode based on the message cell and send to RAC like this, carry out buffer memory by RAC then, after RAC found terminal, RAC was carried at the CID message that obtains in the specific signaling message and sends to personal terminal by air wireless interface.With reference to Fig. 2, according to the V5+ agreement, require cid information with form based on information unit, send the VCN module of RAC by V5PSTN agreement control messages to by LE, and then pass to PS by BS by VCN.
The V5+ agreement realizes that the method for CID business revised the V5 consensus standard, and, owing to do not re-use the baseband transmission mode when requiring LE to send CID message, and adopt mode based on the message cell, switch software need carry out corresponding modification and upgrading.But based on the switch development that sends cid information in the baseband transmission mode the earliest,, that is to say that the switch of most process upgrading is not supported the V5+ agreement, can't realize the CID business of PHS so this class switch proportion is sizable.On the other hand, cadenced ringing tone and two information units of pulse signal after the V5+ expansion are not included the ITU-T standard in, and the V5+ agreement only gains recognition in certain areas at present, uses the Personal Handyphone System(PHS) that also only limits to certain areas.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method in wireless access network realization CID business, makes switch can use the mode based on the baseband transmission cid information to realize the CID business.

Embodiment
The present invention includes following steps: at first, LE receive to personal terminal PS go into to call for ask after, carry out information interaction with VCN, set up the service bearer passage of LE to EVC; Then, LE sends to EVC with the DTMF/FSK aspect by described service bearer passage with cid information; Then, EVC receives the DTMF/FSK signal, and the DTMF/FSK signal decoding is reduced to cid information; EVC sends to VCN with cid information then; VCN is transferred to BS with the cid information that receives, and sends to PS by BS by air wireless interface.
Following flow chart with reference to the CID service implementation example shown in Fig. 3 realizes that at wireless access network the method for CID business is elaborated to of the present invention.In the present embodiment, on the EVC of RAC module, increase DTMF/FSK signal decoding module, be exclusively used in and from the pcm stream that LE transmits, receive the DTMF/FSK signal decoding and go out cid information.Wherein, DTMF/FSK signal decoding module can be realized by the high-speed dsp chip.
Step 301:LE receive to personal terminal PS go into to call for ask after, a time slot that will use in the assignment V5 interface, i.e. V5 Traffic Channel of assignment; LE sends to the VCN of RAC module and distributes (ALLOCATION) message then, starts the distribution of service bearer passage, carries the channel number (V5 Channel Identifier) of the V5 Traffic Channel of institute's assignment in this message.
Step 302:VCN module receives ALLOCATION message, sends open walk (Open_Channel) message to the EVC module, and wherein Open_Channel message carries the V5 Traffic Channel number (V5 Channel Identifier) that step 301 sends over.
After step 303:EVC module receives Open_Channel message, distribute the EVC passage of a free time, and this EVC passage and described V5 Traffic Channel are connected, as the service bearer passage that be used to transmit cid information of EVC to LE in the EVC inside modules.After this service bearer passage is set up successfully, echo to the VCN module and to answer the message open walk to finish (Open_Channel_Comp), the channel number (EVC Channel Identifier) of the EVC passage that notice VCN module is distributed.
After step 304:VCN module is received Open_Channel_Comp, assigned (ALLOCATION_COMP) message to the LE loopback, expression EVC has successfully built to the service bearer passage of LE and has finished.
After step 305:LE receives ALLOCATION_COMP, send to the VCN module at once and set up (ESTABLISH) message, wherein, the pulse pattern of the pulse signal information unit (Ps) that ESTABLISH message is carried is an initial ringing, this Ps is the information unit of the PSTN agreement of V5 interface standard, is not the special burst signal message unit of the portability CID that defines in the V5+ agreement.
After step 306:VCN receives described ESTABLISH message, send the Indication message that begins to receive cid information (Start_Rcv_Cid_Ind) to EVC, indication EVC uses the EVC service channel that is distributed to begin to collect the digits; This message carries above-mentioned EVC service channel number (EVCChannel Identifier) at least, and EVC collects the digits in respective channel with indication.
If the LE number of sending out mode----FSK or DTMF mode dispose at VCN in advance, also need in this message, the number of sending out mode be carried to EVC by sending out number sound type (Signal Type) cell, indication EVC decodes by identical mode.
After step 307:EVC receives the Start_Rcv_Cid_Ind Indication message, use the passage of appointment to prepare to collect the FSK/TDMF signal, and return to VCN and to begin to receive cid information response (Start_Rcv_Cid_Rsp), expression EVC module can begin to collect the digits.
If the EVC module can't collect the digits, only influence the reception of caller cid information owing to collect the digits, to whole calling procedure did not influence, then withdraw from this flow process, continue according to the general calling flow process.
After step 308:VCN receives Start_Rcv_Cid_Rsp, return foundation to LE and confirm (ESTABLISH_ACK) message, expression RAC has been ready to collect the digits.
Step 309:LE receives ESTABLISH_ACK message, to send out number mode----FSK or DTMF mode on the service bearer passage of putting up according to what LE went up configuration, cid information is sent to EVC, EVC receives FSK or dtmf signal on the corresponding service channel, and by DTMF/FSK signal decoding module cid information is decoded out one by one, carry out buffer memory.
Step 310: after LE distributes the FSK/DTMF signal, send signal (SIGNAL) message, carry the cadenced ringing tone information unit (CadencedRinging) of V5 standard P STN agreement in this message to VCN.
After step 311:VCN module is received described SIGNAL message, send out to EVC at once and collect CID end indication (Rev_Cid_Comp_Ind) message, indication EVC module finishes to collect the digits operation.
Step 312:EVC module receives that the Rcv_Cid_Comp_Ind Indication message then finishes the operation that collects the digits, and the cid information of the buffer memory of will decoding is packaged in and collects CID and finish to be uploaded to the VCN module in response (Rcv_Cid_Comp_Rsp) message.
Step 313:VCN module is carried at the CID message that obtains in the specific signaling message, passes to BS, sends to personal terminal by BS by air wireless interface again.RAC is identical with the step that CID is handed down to PS in this step and the prior art, below brief description only:
VCN is carried at cid information in the MS information record (MS Info Record) of air interlace channel assignment request (Assignment Request) message and passes to BS when indication BS assignment air interlace channel.After BS finishes the air interlace channel assignment, cid information is carried in ringing information (Alertwith Info) signaling message sends to personal terminal PS, by the PS display of calling information.
In addition, for step 313, if the VCN function is embedded among the BS, then cid information is directly to be kept in the BS, does not need interaction message between VCN and BS, issues PS and directly cid information is carried in the Alert with Info.
In addition, for step 313, if VCN is not an air interlace channel assignment request initiating terminal through taking, then need air interlace channel assignment originating end before sending Assignment Request message, to obtain cid information from VCN earlier, then cid information is placed Assignment Request message to send to BS to BS; Perhaps when BS receives air interlace channel assignment request, initiatively ask for cid information to VCN, after collecting the message of asking for cid information at VCN cid information is sent to BS, and if the flow process that collects the digits of VCN finishes as yet at this moment, then VCN can directly return the response of not carrying cid information to BS, not influence current calling.
In addition, follow-up when setting up voice traffic channel, can use the service bearer passage of when transmitting cid information, setting up as the voice traffic channel of LE, and set up the voice traffic channel of EVC, and described two voice traffic channel are taken the net connection to BS by the VCN assignment to EVC.Certainly, also can set up the voice traffic channel of LE in addition to EVC.
In above scheme, except message between VCN and the EVC is self-defined message, other are standard interface message.By above step, in wireless access network, can realize that LE sends cid information based on the base band mode.
Though the Radio Access Network that is based on the V5 interface that above embodiment describes, same domain those skilled in the art are understood that, this method not only is applied to the V5 interface, to the Radio Access Network that constitutes with any possibility interface between RAC and the LE, as long as LE is based on the base band mode and transmits cid information, can use mentality of designing of the present invention to realize that Radio Access Network transmits the CID function.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
