Description

A method of accessing a mobile communication device

technical field

The invention relates to a method for accessing a mobile communication device, in particular to a method for authenticating a mobile communication device through a home location register and connecting it to other mobile communication devices.

Background technique

With the increasingly mature communication system, users use mobile communication devices such as mobile phones and PDAs to communicate more and more frequently, and some applications based on the communication system also increase accordingly. It is possible to use a mobile communication device to communicate on a call every day, and one often encounters calls that one does not want to answer or calls are required to be answered when it is inconvenient. In industry applications, since these industry applications are specially developed for internal staff, some outsiders are not suitable for dialing access. However, in reality, there are often dialed wrong numbers to request access to industry application servers.

In the prior art, a user can set a black and white list for a mobile communication device such as a mobile phone to prevent unwanted calls. The user sets the phone numbers that he does not want to answer as a blacklist, but in this method of setting the blacklist, the user must know the phone number of the other party in advance. Once the person changes the number, the blacklist function will not work for the person, and it may be A phone call I didn't want to answer was answered by mistake. Users can also use the white list function to set the phone number they want to answer as a white list, but the user must also know the phone number of the other party in advance. Once the person changes the number, he can no longer call in; at the same time, because some calls may be allowed Accessed, but because it is not in the white list, the user's request for incoming calls is restricted, and the calls that need to be accessed are missed.

An intelligent stealth function is provided in the existing business communication mobile phone, that is, the calls that do not want to answer can be answered through the red and black list, select the business card to answer or select the function of specifying the business card to answer. But these red and black lists answer, select business card to answer or select designated business card to answer and there is the same shortcoming as above-mentioned, the user must know the phone numbers of these people in advance to set, once some people change the phone number, it is possible that they will not want to answer the call If you make a wrong call, you may miss the call you want to answer.

However, in some industrial applications, blacklists or password authentication can be set on the server side to restrict mobile communication devices that require access. In these telephone calls that require access to the server, the user must first access the communication system, that is, the user has already made a call before accessing these servers for industrial applications. And in this process, the user has dialed the phone, therefore has been billed, has caused certain economic losses to these users. As mentioned above, the black and white list cannot restrict users very well, and it is also possible to miss the numbers that are allowed to access. Setting password authentication, as mentioned above, will cause certain economic losses to user access.

Contents of the invention

The purpose of the present invention is to solve the defects in the prior art, and provide a called exchange that utilizes the authentication of the first additional code by the access verification system to allow the call request initiated by the mobile communication device to access the communication system.

To achieve the above object, the present invention provides a method for accessing a mobile communication device. The method includes the following steps:

Step 1: The mobile communication device initiates a call request carrying the first mobile station ISDN number (MSISDN) number, the first additional code information and the International Mobile Subscriber Identity (IMSI) information to the calling exchange; wherein, the first mobile The station ISDN number (MSISDN) number is the MSISDN number of the called mobile communication device, the first additional code information is the additional code information of the called mobile communication device, and the IMSI information is the IMSI information of the calling mobile communication device;

Step 2: The calling switch sends a query message carrying the first MSISDN number, the first additional code and IMSI information to the access verification system;

Step 3: According to the first MSISDN number, query the subscription information in the access verification system, obtain the stored second additional code, and compare whether the first additional code and the second additional code are consistent, and if so, execute Step 4; otherwise end;

Step 4: The access verification system returns a message of allowing the call request to be connected to the called switch to the calling switch.

It can be known from the above technical solutions that the present invention verifies the first additional code through the access verification system, allowing the calling switch to transfer the call request initiated by the verified mobile communication device to the called switch. Therefore, the present invention can avoid the defects of the prior art. It is not a simple number distinction to restrict user call access, but realizes that the mobile communication device user or the application server can conveniently manage the users who allow call access, and can overcome Misanswered calls or missed calls that may be caused by the existing black and white lists will not be harassed by unwanted calls.

The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

Detailed ways

In order to well solve the defects in the prior art, the present invention uses a home location register as an access verification system in a non-intelligent network such as a 2G network to perform the first call access request initiated by a mobile communication device such as a mobile phone. Additional code verification, only through the verification, the call request is allowed to be sent to the exchange of the called object. As shown in Figure 1, it is a flowchart of Embodiment 1 of accessing a mobile communication device in a communication system of the present invention, including the following steps:

Step 11: User A wants to call user B's phone number +8613912345678 and the first additional code such as 8899 through a mobile communication device such as mobile phone A, and initiates an IMSI with the first MSISDN number +8613912345678 and the first additional code such as 8899 and mobile phone A Call request for information to calling switch;

Step 12: The calling switch sends the query message carrying the first MSISDN number +8613912345678, the first additional code 8899 and the IMSI information to the HLR;

Step 13: Query the subscription information in the HLR according to the first MSISDN number +8613912345678, obtain the stored second additional code such as 8899, compare whether the first additional code such as 8899 is consistent with the second additional code 8899, if yes, perform step 14 ; otherwise end;

Step 14: The HLR returns to the calling exchange a message allowing the call request to be forwarded to the called (subscriber B) exchange.

Through the above technical solution, user A wants to call user B whose phone number is +8613912345678. At this time, when user A calls, input user B's phone number, namely MSISDN and additional code 8899, and initiate a call request to the calling switch. At this time, the calling switch must send the information of the telephone number and the additional code to the home location register, which will verify the additional code, so that only the user A who has passed the verification, the calling switch will send the call request to the called switch ; Otherwise, user A will be refused to access the communication system to make a voice call with user B. In this way, user B can reject some calls that he does not want to answer. The Home Location Register here acts as an access verification system.

Of course, the technical solution of Embodiment 1 can be applied in time-sharing, which can better meet the needs of users. The user can set it at 20:00-7:00 in the evening to require all incoming calls to pass the additional code authentication. In the subscription information in the register, the user's request will be recorded. That is, the following steps are included between step 12 and step 13 of embodiment 1: Step 10: inquire into the subscription information of the home location register according to the telephone number of user second, the additional code verification time frame that user second sets is as 20: 00-07:00, the HLR judges whether the system time is within the range of 20:00-07:00, if yes, execute step 13; if not, execute step 14. As shown in Figure 2, Example 2.

In order to better combine with the existing black and white list technology, user B can also allow all users in the white list to allow access to their calls, and add additional codes to phone numbers that do not belong to the white list. After verification, user B can be called. As shown in Figure 3, it is a flowchart of Embodiment 3 of the present invention, including the following steps:

Step 31: User A wants to call user B's phone number +8613912345678 and the first additional code such as 8899 through a mobile communication device such as mobile phone A, and initiates an IMSI with the first MSISDN number +8613912345678 and the first additional code such as 8899 and mobile phone A Information call request to the calling switch;

Step 32: The calling switch sends the query message carrying the first MSISDN number +8613912345678, the first additional code 8899 and the IMSI information to the HLR;

Step 33: According to the IMSI information in the call request, the HLR obtains the second MSISDN number of user A's mobile communication device, such as +8613912348888, and queries the subscription information of user B in the HLR according to the first MSISDN number +8613912345678, and judges Whether the second MSISDN number of user A, such as +8613912348888, exists in the list of allowed access numbers in the subscription information, that is, in the white list set by user B, if yes, go to step 35; if not, go to step 34;

Step 34: Query the HLR subscription information according to the first MSISDN number of user B +8613912345678, obtain the stored second additional code such as 8899, and compare whether the first additional code such as 8899 is consistent with the second additional code, if yes, go to step 35 ; otherwise end;

Step 35: The HLR returns a message allowing the call request to be forwarded to the called switch to the calling switch.

Through the technical solution shown in embodiment 3, the existing white list technology is used in conjunction with the present invention to better prevent the user's phone number not in the white list but the phone that user B wants to answer from being filtered out . As long as user A enters the correct additional code, he can be connected even if he is not in the white list.

Of course, it can also be combined with the existing blacklist technology. In the embodiment 4 combined with the blacklist, the processing flow is a little different from the processing flow of embodiment 3, only step 33 is different. In this embodiment, step 33 It is: according to the IMSI information in the call request, the HLR obtains the second MSISDN number of the mobile communication device of user A, such as +8613912348888, and queries the subscription information of user B in the HLR according to the first MSISDN number of user B +8613912345678 , to determine whether the second MSISDN number of user A such as +8613912348888 exists in the list of disallowed access numbers in the subscription information, that is, in the blacklist set by user B, if yes, then perform step 34; if not, then perform step 35 That is, in the present embodiment, user A wants to dial the phone of user B, if user A is a blacklist user of user B, user A can also get through the phone of user B through the verification of additional code, thus avoiding user After user A is set as a blacklist user by mistake, user A cannot dial in a call to user B's mobile communication device such as a mobile phone.

In addition to the non-intelligent network, the intelligent network also provides a first additional code verification for a call access request initiated by a mobile communication device such as a mobile phone by using a home location register and a service control point (SCP) as an access verification system. Only through verification, the call request is allowed to be sent to the switch of the called object.

As shown in Figure 4, it is a flow chart of Embodiment 5 of the present invention, which specifically includes the following steps:

Step 41: User A wants to call user B's phone number +8613912345678 and the first additional code such as 8899 through a mobile communication device such as mobile phone A, and initiates an IMSI with the first MSISDN number +8613912345678 and the first additional code such as 8899 and mobile phone A Information call request to the calling switch;

Step 42: The calling switch sends the query message carrying the first MSISDN number +8613912345678 and the first additional code 8899 and the IMSI information of mobile phone A to the service control point of the access verification system, and the service control point forwards the query message , to the home location register of the access verification system;

Step 43: According to the first MSISDN number of user B +8613912345678, query the subscription information of user B in the home location register, and obtain the stored second additional code of user B such as 8899;

Step 44: The HLR returns the second additional code to the service control point;

Step 45: The service control point compares whether the first additional code 8899 and the second additional code 8899 are consistent, if yes, execute step 46; otherwise end;

Step 46: The service control point returns a message of allowing the call request to be forwarded to the called switch to the calling switch.

After user B passes the above technical solution, the calling switch can also verify the call request initiated by user A in the intelligent network before sending the call request to the called switch; otherwise, user A will be denied access to the communication system to make a voice call with user B. In this way, user B can reject some calls that he does not want to answer.

Like the technical solution of embodiment 2, in embodiment 6, it can also be applied in time-sharing, which can better meet the needs of users. Users can set the requirement that all incoming calls must pass through the additional Code authentication, in the subscription information in the home location register, the user's request will be recorded. That is, the following steps are included between step 42 and step 43 of embodiment 5: inquire into the home location register subscription information according to the telephone number of user second, the additional code verification time frame that user second sets is as 20:00-07: 00, determine whether the system time is within the range of 20:00-07:00, if yes, execute step 43; if not, execute step 46.

It can also be used together with a black and white list in a non-intelligent network as shown in Embodiment 3. In this embodiment 7, in an intelligent network, the scheme shown in Embodiment 5 is used together with a white list, that is, in steps 42 and 43 Including: Step 40: According to the IMSI information in the call request, obtain the second MSISDN number of user A's mobile communication device from the home location register, and query the subscription information according to the first MSISDN number of user B, and determine the second MSISDN number of user A. Two MSISDN numbers such as whether +8613912348888 exists in the allowed access number list in the subscription information, that is, in the white list set by user second, if yes, then perform step 46; if not, then perform step 43; like this by embodiment 7 According to the technical solution shown, the existing white list technology is used in conjunction with the present invention to better prevent the phone numbers of users not in the white list but the calls that user B wants to answer from being filtered out. As long as user A enters the correct additional code, he can be connected even if he is not in the white list.

Of course, it can also be combined with the existing blacklist technology. In the eighth embodiment combined with the blacklist, the processing flow is a little different from the processing flow in embodiment 7. Only step 40 is different. In this embodiment, step 40 It is: according to the IMSI information in the call request, the HLR obtains the second MSISDN number of the mobile communication device of user A, such as +8613912348888, and queries the subscription information of user B in the HLR according to the first MSISDN number of user B +8613912345678 , to determine whether the second MSISDN number of user A such as +8613912348888 exists in the list of disallowed access numbers in the subscription information, that is, in the blacklist set by user B, if yes, then perform step 43; if not, then perform step 46 That is, in the present embodiment, user A wants to dial the phone of user B, if user A is a blacklist user of user B, user A can also get through the phone of user B through the verification of additional code, thus avoiding user After user A is set as a blacklist user by mistake, user A cannot dial in a call to user B's mobile communication device such as a mobile phone.

Of course, in Embodiments 1-8, the calling number initiated by user A may be the phone number of individual user B or the access number of a certain application server. As long as the user has customized the service of this additional code, the network side will send the information of these additional codes to all users who are allowed to make calls by the user through SMS. Of course, the user can also notify his relatives and friends of his additional code. When other users want to dial his phone, the network side verifies the phone access according to the service selected by the user, such as the user customizes an additional code and uses it with the blacklist, and applies the specific solutions of the above-mentioned embodiments to realize the connection with the user connected.

Through the present invention, it can be realized that the mobile communication device user application server can manage the users who are allowed to call in, and it is not a simple number distinction to restrict the user's call access, which can overcome the possible wrong call or wrong call caused by the existing black and white lists. Missed calls.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be The scheme shall be modified or equivalently replaced without departing from the spirit and scope of the technical scheme of the present invention.
