Description
Technical Field
The invention relates to a forwarding service processing technology, in particular to a method and a device for avoiding mistakenly setting an invalid forwarding Number (FTN).
Background
The call forwarding service means that the user forwards the own incoming call to the terminal corresponding to the other preset telephone number, and the call forwarding service can be activated without influencing the user to initiate a call. The call forwarding service, which is an important component of supplementary services in mobile networks, is now widely used and provides great convenience for communications of mobile users. According to the related flow of Global system for Mobile Communications (GSM) supplementary services, when a Mobile subscriber needs to use a call forwarding service, the FTN may be set on a Mobile terminal such as a Mobile phone, for example, by a Mobile phone menu mode or a Man-Machine interface (MMI) command mode.
However, in the current FTN setting procedure of the mobile subscriber, except that the Home Location Register (HLR) may simply check whether the FTN belongs to the number for which forwarding is prohibited, no deep determination can be made on the validity of the FTN.
Currently, the forwarding prohibited number analysis table set on the HLR usually only limits the numbers that obviously cannot be forwarded, for example, the emergency special service number like 110, the customer service number like 10086, the government service number like 12345, etc., through which the HLR can intercept these FTNs. However, in addition to the FTN prohibition, the mobile user often has wrong settings in various situations when performing call forwarding settings. For example:
1) when the FTN is set, a plurality of digits are input less or more, so that the FTN is invalid;
2) when the FTN is set, although the bit length is correct, a plurality of digits have deviation, so that the FTN becomes a null number;
3) when the FTN is set, some special service numbers, such as short message center numbers, are set by mistake;
4) when the FTN is set as a mobile number B, the mobile number B is stopped;
5) when the FTN is set as the mobile number B, the mobile number B itself has set unconditional forwarding, which results in that the user cannot normally use the call forwarding service due to the "secondary call forwarding" restriction.
For the above situations of various wrong settings, it is impossible to perform FTN analysis only by means of HLR, and the various wrong settings are infinite in reality, which seriously affects the service awareness of the mobile subscriber.

Detailed Description
In the prior art, a method for implementing FTN setting is shown in fig. 1, and specifically includes the following steps:
step 101: a Mobile Station (MS, Mobile Station) reports a REGISTER Supplementary Service (REGISTER _ SS) message to an MSC/VLR;
in the call setup process, the mobile subscriber reports the call type and the FTN to be set to the currently registered MSC/VLR device in a menu mode or an MMI instruction mode on the MS.
Call forwarding types can be divided into four different types, unconditional call forwarding, busy call forwarding, unreachable call forwarding and no-answer call forwarding.
Step 102: after receiving the above message, MSC/VLR sends message of Mobile Application Part REGISTER Supplementary Service (MAP _ REGISTER _ SS, Mobile Application Part _ REGISTER _ supplementationservice) to HLR to which MS belongs;
step 103: after the HLR simply checks that the FTN does not belong to the number prohibited from forwarding, the HLR returns a message of Supplementary Service registration (MAP _ REGISTER _ SS _ ack, Mobile Application Part _ REGISTER _ Supplementary Service _ acknowledgement) to the MSC/VLR, simultaneously updates the user DATA in the HLR, and inserts a message of user DATA (MAP _ INS _ SUBS _ DATA, Mobile Application Part _ Insert _ SUBS _ DATA) to inform the MSC/VLR of updating;
step 104: the MSC/VLR returns a message of REGISTER _ SS _ ack (REGISTER _ complementary Service _ acknowledgement) to the MS to confirm that the FTN is successfully set.
In the above conventional call forwarding setting procedure, the HLR is only used to determine whether the FTN is not allowed to perform call forwarding, but there is no way to perform other types of invalid call forwarding. Therefore, the embodiment of the present invention takes the operation of the MS-A performing FTN setting as an example, and further describes in detail A specific procedure for avoiding false setting of an invalid FTN.
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 2 is A schematic diagram illustrating an implementation flow of A method for avoiding false setting of an invalid FTN according to an embodiment of the present invention, where the embodiment of the present invention is implemented in A network environment based on that shown in fig. 1, an MSC/VLR- A obtains A final FTN registered by an HLR- A from A MAP _ REGISTER _ SS _ ack message returned by the HLR- A, and performs called number analysis on the FTN; the FTN generally includes information such as a Country Code (CC), a National Destination Code (NDC), and an area Code. Here, HLR- A is the HLR to which the subscriber performing call forwarding setting belongs, and HLR-B is the HLR to which the FTN belongs when the FTN is A normal home network mobile number.
As shown in fig. 2, an implementation flow of the method for avoiding false setting of an invalid FTN in the embodiment of the present invention includes the following steps:
step 201: obtaining an FTN;
step 202: analyzing the effectiveness of the obtained FTN;
step 203: and when the FTN is determined to be invalid, the MSC/VLR sends out USSD message reminding with the reason of the invalid FTN according to the analysis result.
Here, for different analysis results, the following processing methods may be specifically provided:
the first method is as follows: when FTN is normal fixed telephone number or other network mobile number, MSC/VLR-A terminates the following call connection process, and directly transfers to step P5; here, the other-network mobile number refers to a mobile number in another network different from the network to which the mobile number used by the current mobile subscriber belongs;
the second method comprises the following steps: when the FTN is A normal home network mobile number, MSC/VLR-A needs to initiate an HLR query flow to HLR-B, and the step P3 is switched to at the moment;
the third method comprises the following steps: when the FTN is an abnormal fixed telephone number or an abnormal home network and other mobile numbers, the called number analysis fails, and the process proceeds to step P2.
Based on the above several processing modes, a specific implementation of the method for avoiding the false setting of the invalid FTN according to the embodiment of the present invention is shown in fig. 3, and includes the following steps:
step P1: MSC/VLR-A obtains the final FTN registered by HLR-A from MAP _ REGISTER _ SS _ ack message returned by HLR-A, and analyzes the number, when MSC/VLR-A can obtain normal outgoing relay route by analyzing the number of FTN, then it is judged that FTN is normal fixed telephone number or other network mobile number, MSC/VLR-A terminates the following call connection process, and directly goes to step P5;
wherein, MSC/VLR-A is the mobile terminal office registered by MS-A at present, mainly used for processing and forwarding MS-A call forwarding operation request; HLR-A is the HLR equipment to which MS-A belongs and is responsible for specifically executing the MS-A call forwarding operation request.
Step P2: when the MSC/VLR- A analyzes the number of the FTN to obtain an erroneous result, and determines that the FTN may be invalid, it initiates A terminating USSD notification Service message flow, sends an Unstructured Supplementary Service notification (Unstructured Supplementary Service notification) message to the MS- A, and goes to step P5;
wherein, the message content of the untranstruredsjnotify message is similar to "please note: the call forwarding number set by the user is possibly wrong, and the user asks to verify whether the number is input with wrong information;
step P3: when MSC/VLR-A finds that FTN is normal home network Mobile number (MS-B), then according to calling Mobile subscriber's flow, sending route Request message (MAP _ Send _ Routing _ Info _ Req, Mobile Application Part _ Send _ Routing _ InformationRequest) to HLR-B initiating Mobile Application Part;
here, the Mobile Application Part sending route confirmation message (MAP _ Send _ Routing _ Information _ ack, Mobile Application Part _ Send _ Routing _ Information _ acknowledgment) returned by the HLR-B may carry the following results:
a) if the message returned by HLR-B carries A "User error" cell and the parameter value is "unknown subscriber", it indicates that the FTN does not exist in HLR-B, at this time, step P4 is entered, MSC/VLR- A sends an untranstructedss _ Notify message to MS- A, and the message content is similar to "please note: if the call forwarding number set by the user does not exist, the user asks to verify whether the number is input with wrong information; then go to step P5;
b) if the message returned by HLR-B carries "User error" cell and the parameter value is "Call Barred", it indicates that the FTN is shut down, at this time, step P4 is entered, MSC/VLR- A sends an untranstructedss _ Notify message to MS- A, and the message content is similar to "please note: the call forwarding number set by the user is stopped, and the user cannot normally use the information of the call forwarding service; then go to step P5;
c) if the message returned by HLR-B carries A forwarding datA cell and the parameter value of forwarding-release is "Unconditional", it indicates that the FTN itself has set Unconditional forwarding, at this time, step P4 is entered, MSC/VLR- A sends an Unconditional ss _ Notify message to MS- A, and the message content is similar to "please note: the call forwarding mobile phone number set by a user sets unconditional call forwarding, and the call forwarding service can not be normally used by the user; then go to step P5;
d) for other returned results, MSC/VLR-A judges FTN is normal and effective home network mobile number, at this moment, MSC/VLR-A terminates the subsequent call connection flow, directly enters step P5;
here, for other returned results, HLR-B may need to Provide a Mobile application part Roaming Number request (MAP _ provider _ Routing _ Number _ Req) message to MSC/VLR-B requesting that MS-B be assigned a Mobile Station Roaming Number (MSRN).
Step P4: MSC/VLR-A initiates A flow of A terminating USSD notification service message, sends an unscattered SS _ Notify message to MS-A, and sends different message contents according to the invalid conditions;
step P5: MSC/VLR-A replies A REGISTER _ SS _ ack message to MS-A, and ends the call forwarding setting process.
