orreq response which may further carry a display text (DisplayText) parameter, the parameter DisplayText carries the called terminal needs to be displayed is determined VPN cornet .SCP VPN service calling terminal and the account activation 频充足后,可根据设置的主叫号码显示规则,确定VPN业务中被叫终端上显示的主叫号码为VPN短号,因此,向始发MSC提供VPN短号.VPN短号也可不在本步骤中提供给始发MSC,而是在步骤104中提供给始发MSC.步骤103:始发MSC收到orreq响应后,触发主叫路由可得(Calling_Routing_Address—Available )触发器,向对应于该触发器的SCP 发送ANLYZD消息,该ANLYZD消息中携带有主叫MSCID、 MSID、 BILLID、 TRIGTYPE等参数.步骤104: SCP收到ANLYZD消息后,向始发MSC返回anlyzd响应, 该anlyzd响应中携带有被叫终端真实号码(TerminationList)等参数.如果步骤102中SCP未向主叫MSC提供参数DISPLAYTEXT,则anlyzd响应中可进一步携带有参数DISPLAYTEXT,该DISPLAYTEXT参数中携带有需要被叫终端显示的VPN短号.步骤105:被叫MSC收到呼叫后,触发终呼初始(Initial—Termination) 触发器,并向该触发器中指定的SCP发送ANLYZD消息,该AN After sufficient frequency, the calling number may be displayed according to the set rules, to determine the calling number displayed on the VPN service is called VPN cornet terminal, thus providing VPN cornet cornet .VPN may not be present in the originating MSC step provided to the originating MSC, but to provide to the originating MSC in step 104. step 103: the originating MSC receives orreq response, triggering the calling route available (Calling_Routing_Address-available) flip-flop, corresponding to the the SCP sends ANLYZD message trigger, the message carries the calling ANLYZD MSCID, MSID, BILLID, TRIGTYPE parameters step 104: after the SCP receives ANLYZD message, the MSC returns to the originating anlyzd response, the response carries anlyzd real number of the called terminal (the TerminationList) parameters. If the SCP in step 102 is not provided DisplayText parameters to the calling MSC, the anlyzd response parameters may further carry DISPLAYTEXT, DisplayText parameter which carries the called terminal needs a short display VPN number step 105: the called MSC receives the call, terminating the initial trigger (initial-Termination) trigger, and sends ANLYZD message to the specified trigger the SCP, the AN LYZD消息中携带有被叫MSCID、 MSID、 BILLID、 TRIGTYPE等参数.步骤106: SCP收到ANLYZD消息后,确定被叫终端激活VPN业务并且帐户余额充足,然后向被叫MSC返回anlyzd响应,该anlyzd响应携带有DMH—SVCID,表明当前触发了VPN业务.步骤107〜步骤108:被叫MSC收到anlyzd响应后,触发被叫路由可得(Called_Routing_Address_Available)触发器,并向该触发器中指定的SCP 发送ANLYZD消息.SCP收到ANLYZD消息后,向被叫MSC返回anlyzd 响应.步骤109〜步骤110:始发MSC和被叫MSC建立呼叫,被叫终端应答, 被叫MSC触发被叫应答(T_Answer)触发器,并向该触发器中指定的SCP 发送TANSWER消息,该TANSWER消息中携带有被叫MSCID、 MSID、 BILLID、 TRIGTYPE等参数;始发MSC触发主叫应答(O—Answer)触发器,并向该触发器中指定的SCP发送OANSWER消息,该OANSWER消息中携带有始发MSCID、 MSID、 BILLID、 TRIGTYPE等参数.主叫终端与被叫终端进 LYZD message carries the called MSCID, MSID, BILLID, TRIGTYPE parameters Step 106: After the SCP receives ANLYZD message, the called terminal is determined and sufficient to activate the VPN service account balance, and then returns to the called response to the MSC anlyzd, the anlyzd response carries DMH-SVCID, the VPN service indicates that the current triggering step 107~ step 108: after the MSC receives the called response anlyzd triggering called route available (Called_Routing_Address_Available) flip-flop, the flip-flops to the designated SCP after sending the message ANLYZD received .SCP ANLYZD message, returns to the called MSC ANLYZD response step 109~ step 110: establishing a call originating MSC and the called MSC, the called terminal answers, the called MSC triggers called response (the T_Answer) flip-flop, the flip-flop to the designated SCP sends TANSWER message, the message carries the called TANSWER MSCID, MSID, BILLID, TRIGTYPE parameters; originating MSC triggering the caller responses (O-answer) flip-flop, and to trigger the specified OANSWER SCP sends message, the message carries the originating OANSWER MSCID, MSID, BILLID, TRIGTYPE other parameters into the calling terminal and the called terminal 通信.在以上所述的过程中,还包括始发MSC将VPN短号作为需要显示的主叫号码提供给被叫MSC,被叫MSC在向被叫终端振铃时,将该VPN短号提供给被叫终端显示.以上所述的需要被叫终端显示的显示号码是通过移动应用部分(MAP) 信令中的始呼请求响应(OriginationRequest RETURN RESULT)消息,即orreq响应消息,或分析信息响应(Analyzedlnformation RETURN RESULT) 消息,即anlyzd响应消息中的DISPLAYTEXT参数携带的;还可通过OriginationRequest RETURN RESULT响应消息、或Analyzedlnformation RETURN RESULT响应消息中的主叫号码数字(CallingPartyNumberDigitl ) 参数或主叫号码字符串(CallingPartyNumberStingl)参数携带,以上携带显示号码的参数也可为扩展参数.始发MSC收到携带有DISPLAYTEXT参数、CallingPartyNumberDigitl 或参数CallingPartyNumberStingl的消息后,将主叫号码更改为相应参数中携带的显示号码,然后通过被 Communication. In the above process, further comprising the originating MSC to the called MSC VPN cornet provided to be displayed as the calling number, called MSC during ringing to the called terminal, and the VPN providing cornet to the called terminal display displays the desired number of the called terminal according to the above display is performed by the mobile application part (MAP) signaling originating call request response (OriginationRequest RETURN RESULT) messages, i.e. orreq response message, or analysis information response (Analyzedlnformation RETURN RESULT) messages, i.e. DISPLAYTEXT parameter response message anlyzd carried; further response message OriginationRequest RETURN RESULT, or in response to a calling number Analyzedlnformation RETURN RESULT number (CallingPartyNumberDigitl) parameters in the message or calling number string ( after CallingPartyNumberStingl) parameter carries, carrying the above parameters may also be displayed number. DISPLAYTEXT carrying the originating MSC receives parameters, CallingPartyNumberDigitl CallingPartyNumberStingl message or parameter is extended parameter, change the displayed calling number for number portability in the corresponding parameters, and by being 叫MSC提供给被叫终端显示.另外,也可在各信令中通过自定义新的参数携带需要被叫终端显示的显示号码.方式一可通过MAP信令传送需要显示的号码这种处理方式适合于大的移动运营商,在移动通信网络上能够方便地通过MAP信令来传递需要显示的号码,非常便于扩展业务.方式二、三可以通过MAP信令或中继信令传送需要显示的号码,此方式适合于既运营固定通信网络又运营移动通信网络的综合运营商.通过中继信令传送时,由于中继信令无法传递DISPLAYTEXT参数,所以只能转换到与中继信令对应的主叫号码参数中。 MSC provides call to the called terminal display. Further, since the number may be displayed by the definition of the need to carry new parameter called terminal displays in each signaling. A manner to be displayed can be transmitted through the MAP signaling approach such numbers suitable for large mobile operators in the mobile communication network can be conveniently transferred numbers to be displayed by MAP signaling, it is easy to expand. manner two, three may be transmitted to be displayed by MAP signaling or signaling relay number, which is suited for both the operator and the fixed communication network operator of the mobile communication network of the integrated operator when conveyed through the trunk signaling, the signaling can not be transmitted since the relay DISPLAYTEXT parameters, only transition to the corresponding signaling relay caller ID parameter. 另外,如果采用现有协议中定义的参数,则会对协议的改动较小,使得具体实现更为快捷方便.以上所述过程实现了被叫终端显示网络侧提供的号码,下面以方式一为例说明被叫终端显示该号;4A实现回拨的实现原理.如果需要实现被叫终端能够根据该显示号码,将呼叫回拨至相应用户,则在始发MSC向被叫MSC提供DMH—SVCID参数,被叫MSC根据DMH—SVCID参数的值,将该DISPLAYTEXT参数映射至空中接口正确的参数,如通过A接口的主叫号码(Calling Party ASCII Number )参数传递,即被叫MSC中根据DMH—SVCID 的值为优先显示参数DISPLAYTEXT中号码的业务时,将DISPLAYTEXT 参数与空中接口的Calling Party ASCII Number参数相对应,这样,被叫终端就能显示网络侧要求显示的号码,并能够通过回拨显示号码而对相应用户发起呼叫.由于DISPLAYTEXT参数相当于是一个容器参数,根据业务需要可以对应 Further, if the parameters defined in the existing protocol, the protocol will change to smaller, more convenient such that the specific implementation. The above process to achieve the called terminal to display the number provided by the network, in the following manner as a illustrates the number of the called terminal display;. 4A realization principle implemented callback, if desired, can be achieved according to the display of the called terminal number, the call-back call to the user, provides DMH-SVCID originating MSC to the called MSC parameter, called MSC DMH-SVCID according to the value of the parameter, the parameter to map this DISPLAYTEXT correct air interface parameters, such as the calling number is transmitted via the a interface (calling Party ASCII number) parameters, i.e., the called MSC according DMH- when the number of service parameter DISPLAYTEXT SVCID display priority value, the Calling Party ASCII number parameter DISPLAYTEXT parameters corresponding to the air interface, so that the called terminal can display the number required to display the network side, and can be displayed by the callback number and initiate a call to the user. Since the parameter is equivalent to a container DISPLAYTEXT parameters, may correspond to business needs A接口的Display参数、Calling Party ASCII Number参数或其他类似用途的参数,但这些参数中除Calling Party ASCII Number参数外,均只能在被叫终端上显示号码,而无法回拨,因此,如果需要实现回拨,就要将DISPLAYTEXT参数设置为仅与Calling Party ASCII Number参数相对应, 这样被叫MSC就需要知道当前的业务类型,根据相应业务进行正确的映射。 Display interface parameter A, Calling Party ASCII Number parameter or other similar uses, in addition to these parameters Calling Party ASCII Number parameter, are only displayed on the called terminal number, but can not call back, and therefore, if necessary implemented callback, it is necessary only to set the parameters DISPLAYTEXT correspond Calling Party ASCII Number parameter, so called MSC needs to know the current service type, according to the correct mapping corresponding service. 始发MSC向被叫MSC提供的DMH—SVCID参数可携带在LOCREQ消息和ROUTREQ消息中,具体传送过程如下:始发MSC向被叫方的归属位置寄存器(HLR, Home Location Register)发送LOCREQ消息,该LOCREQ 消息中携带有DMH—SVCID参数以及含有显示号码的DISPLAYTEXT参数; HLR收到LOCREQ消息后,向被叫MSC发送ROUTREQ消息,该ROUTREQ 消息中携带有DMI^SVCID参数以及含有显示号码的DISPLAYTEXT参数; 被叫MSC收到ROUTREQ消息后,就获取了DMH—SVCID参数,然后向HLR返回ROUTREQ响应,该ROUTREQ响应中携带有被叫方的漫游号码(TLDN) ; HLR收到ROUTREQ响应后,向SSP返回LOCREQ响应,该LOCREQ响应中携带有被叫MSC提供的TLDN,在被叫MSC向被叫终端振铃时,将显示号码提供给被叫终端显示,并且被叫终端可通过回拨该显示号码向主叫终端发起呼叫.以上所述的MSC还可为MSC/访问位置寄存器(VLR, Visitor LocationRegister)、业务交换点 DMH-SVCID parameters originating MSC to the called MSC may provide in LOCREQ message and carry ROUTREQ message, transmitting the specific process is as follows: the originating MSC sends a LOCREQ message to the home location register of the called party's (HLR, Home Location Register), the LOCREQ message carries parameters and DMH-SVCID DISPLAYTEXT display parameters comprising number; LOCREQ message is received after the HLR sends ROUTREQ message to the called the MSC, which carries a ROUTREQ message parameter, and DMI ^ SVCID DISPLAYTEXT display parameters comprising number ; MSC receives the called ROUTREQ message, to obtain the DMH-SVCID parameters, and then returns a response to the HLR ROUTREQ, the ROUTREQ response carries the roaming number of the called party (the TLDN); ROUTREQ the HLR response is received, the SSP Back LOCREQ response, the response carries LOCREQ provided the TLDN of the called MSC, the MSC of the called ringing to the called terminal, the number is displayed to the called terminal display, and the called terminal can display the number of the callback initiates a call to the calling terminal. MSC above may also be a MSC / visitor location register (VLR, Visitor LocationRegister), the service switching point SSP, Service Switch Point)等;以上所述确定显示号码的实体还可为HLR.总之,以上所述仅为本发明的较佳实施例而已,并非用于限定本发明的保护范围. SSP, Service Switch Point) and the like; determining the number shown above may also be entities HLR summary, the above description is only preferred embodiments of the present invention but are not intended to limit the scope of the present invention.
