Description

An implementation method for providing different service characteristics according to user location

The present invention relates to a switching subsystem in a CDMA (Code Division Multiple Access) mobile communication system, and more particularly to an implementation method for providing different service characteristics according to user locations in mobile communications. Background technique

The CDMA mobile communication system includes MSS (Mobile Switching Subsystem), BSS (Base Station Subsystem), and MC (Short Message Center), SCP (Service Control Point) and other network entities. The user's service characteristics include basic services and supplementary services, basic services such as voice, short message, circuit type data service, and packet data service rights, and supplementary services such as call waiting and call forwarding.

In the existing commercial CDMA mobile communication system, the service characteristics of a user are fixed, and have the same service characteristics regardless of the current location of the user. However, due to the fierce competition in telecommunications operations, there is an urgent need to provide personalized services to users, requiring different business characteristics when users are in different locations. For example: In order to segment users, operators can provide more intimate services, and some low-end users may need to be assigned a smaller area. For example, the coverage of a sector of a BTS (base station), the user can only make voice calls in this area, once this area is exceeded, no service can be performed, or only a short message can be received, so that the service can be exceeded Inbound calls that are restricted in scope are notified to the user in the form of short messages. In this way, it is necessary to be able to customize the service characteristics in each cell in units of CELL (cell) for each user.

In the existing protocol, a similar implementation has a UserZone (user area). The coverage of the entire mobile network is divided into several UserZones. For each user, several UserZones are registered, and the corresponding service list is stored in the HLR (Home Location Register). Terminal registration When the VLR (visit location register) requests the service list from the HLR (home location register), the HLR (home location register) returns the corresponding service list according to the UserZonelD (user area identifier) carried in the received message, and the MSC (mobile exchange) According to this business list, the control of the user's business is realized. However, this method first requires support from the mobile phone and the network, and if the method is minimal in cell units, it will cause the VLR (visit location register) to frequently obtain the service list from the HLR (Home Location Register).

At present, the concept of such a service area is implemented according to a location area, a mobile switching center, or a network, and the HLR maintains a list of services of users under different service areas. When the terminal registers, the location update message sent by the VLR to the HLR is used to carry the service area identifier currently in which the terminal is located, and the HLR determines the LAID (Location Area Identity), the MSCID (Mobile Switch Identity), or the extended service area identification number, etc. Returns the corresponding business list. If the service area is determined in units of cells, this method will result in a large amount of communication traffic between the VLR and the HLR due to the small coverage, causing the network to be overwhelmed.

In summary, it is possible to provide a method for providing different service characteristics according to different locations of users, to realize a communication service with a minimum division of a service area, which does not burden the network operation, nor is it a terminal or a network. Type restrictions have become an urgent problem to be solved in the industry. Summary of the invention

The technical problem to be solved by the present invention is to provide an implementation method for providing different service characteristics according to the location of the user. The terminal has different service characteristics in multiple service areas, and the service area is divided into cells in a minimum, which does not cause network weight, and is not affected by the terminal type and network type.

In order to solve the above technical problems, the present invention provides the following solutions:

A method for providing different service characteristics according to the location of a mobile terminal, in network coverage A plurality of cells are divided into a service area, and the terminal user signs a plurality of the service areas, and corresponding personalized service features, including the following steps:

Configuring, according to the division of the service area, a configuration table including a correspondence between a cell in the coverage of the mobile switching center and a service area for each mobile switching center in the network; and according to the user subscription information, A service area generates a service area personalized service list including a corresponding mobile switching center identifier and corresponding service characteristics, and is stored in the home location register;

When the terminal registers, the home location register retrieves the personalized service list of the service area related to the mobile switching center according to the mobile switching center where the terminal is currently located, and returns to the visited location register;

When the terminal performs the service operation, the mobile switching center determines the current service area by using the configuration table according to the current location of the terminal, and controls the current service of the terminal by using the personalized service list corresponding to the current service area.

The advantages of the present invention over the prior art are:

The method of the invention can implement the minimum cell-based service area service feature control, which facilitates the operator to provide users with more personalized services; each user has a default profile (service list) data, only needs to be targeted to the service area. The individually controlled service features are separately saved and transmitted, saving the space required to store the service feature lists of multiple service areas, and simultaneously realizing the coexistence of users with the service and ordinary users; the user registration and roaming rights remain unchanged. The user service area service feature list is transmitted from the HLR to the VLR for storage at one time, which can effectively reduce the impact of frequent interaction between the VLR and the HLR on the network load.

The technical problems, the technical solutions, and the beneficial effects to be solved by the present invention will be further described with reference to the accompanying drawings. BRIEF abstract

As shown in Figure 1, it is the relationship between the service areas registered by the user.

Here, the service area refers to the area within the network coverage that provides services to users, and is a logical concept. Each service area consists of several cells. The coverage of the entire network is the public service area of all users, and each user has registered service characteristics as the default service characteristics of the user. In addition, some users have also registered a number of personalized service areas in which users have registered different personalized business characteristics. The service segments divided by the system may overlap, but the individual service areas registered by a single user do not overlap each other.

As shown in Figure 2, a flow chart of the method of the present invention.

An implementation method for providing different service characteristics according to a user location, in a network coverage, dividing a plurality of cells into one service area, the terminal user signing a plurality of the service areas, and corresponding personalized service characteristics; And configuring, according to the division of the service area, a configuration table including a correspondence between a cell in the coverage of the mobile switching center and a service area for each mobile switching center in the network (step 101); User subscription information, for each service area, generates a service area personalized service list including the corresponding mobile switching center identifier and corresponding service characteristics, and stores the information in the home location register (step 102); when the terminal registers, the attribution The location register is based on the mobile exchange in which the terminal is currently located. The heart, taking out the personalized service list of the service area related to the mobile switching center, and returning to the visit location register; when the terminal performs a service operation, the mobile switching center determines the current state by using the configuration table according to the cell where the terminal is currently located. The service area controls the current service of the terminal by using a personalized service list corresponding to the current service area (step 103).

The personalized service list records the subscription services of the users in different service areas. Although it is possible for the user to maintain a list of personalized services for each service area, each user does not necessarily have different services in each service area. In fact, most of the services in the service area are the same. Therefore, in order to reduce the amount of data stored and transmitted, a default service list can also be maintained. In the service area where no personalized service is signed, the default service characteristic data can be directly used as the current service feature list. In order to further reduce the amount of data, it is also possible to record only the part that differs from the default business characteristic data in the personalized service list.

The home location register returns the personalized service list of the service area associated with the mobile switching center to the visited location register step, and may also return the default service characteristic data of the terminal together to the visited location register.

Here, the step of returning to the visitor location register may be implemented by: the home location register carrying a personalized service characteristic flag in the registration response message is sent to the visited location register;

After receiving the response message, the visit location register sends an eligibility request message to the home location register according to the personalized service characteristic flag;

The home location register sends the personalized service list data as an eligibility response message parameter to the visited location register via an eligibility response message.

The mobile switching center obtains a personalized service list corresponding to the current service area from the visited location register according to the current service area, which can be implemented by the following steps:

The mobile switching center acquires, from the visited location register, a list of all service areas of the service area related to the mobile switching center; Traversing the related service area personalized service list, and using the configuration table to obtain identifiers of the plurality of cells corresponding to the corresponding service areas, respectively, compared with the cell identifiers obtained from the terminal service messages;

The service area personalized service list including the same cell identifier is determined as the personalized service list corresponding to the current service area.

The controlling the current service of the terminal by using the personalized service list corresponding to the current service area, using the personalized service list to cover the default service characteristic data of the terminal, and forming a list of current service characteristics of the terminal. control.

Since in general, only the difference between service options and service rights needs to be provided, most of the service characteristics are the same. Therefore, these personalized service characteristics are only the difference from the default service characteristics. When the user is in these personalized service areas, the service characteristics of these different parts are used, and the corresponding parts of the default service characteristics are overwritten to obtain the current specific service characteristics. An example of a personalized service area for a personalized service area for the user is shown in the following table: Identification Mobile Switching Center Identity

• .. mainly includes: mobile switching center identification, service area identification, business options, business rights, supplementary services, etc. Among them, the correspondence between the mobile switching center and the service area is given. A user can have multiple such personalized service area business characteristics. In practical applications, the service characteristics that the user needs to customize in relation to the service area are generally small, and only the corresponding items need to be provided according to the user's needs. Therefore, when the system is implemented, the service characteristics customized by the above-mentioned user can be added or deleted according to actual needs, such as reducing the service options of the circuit type data service part, so that the service area service characteristic list data is minimized, so as to facilitate transmission and save.

As shown in Figure 3, a one-time registration process for the mobile station is described.

Below, the message name is in uppercase for the request message and lowercase for the response message.

Including the following steps:

Step 301: The mobile station MS sends a registration message to the base station controller BSC.

Step 302: The base station controller BSC sends a location update request to the mobile switching center MSC; Step 304: The MSC/VLR sends a registration notification request message REGNOT to the HLR;

Step 304: The HLR determines that the originating mobile switch identifies the MSCID, and queries whether the terminal registers the personalized service area service characteristic on the MSC. If not, returns the registration response as before. Should be re _gno t. Otherwise, the service area service characteristic list associated with the MSC is returned as a separate parameter together with the default profile data in the registration response message regnot; in this example figure, since the new parameter is too large, It is easy to encode in the response message, just carry the flag bit, indicating that there is this parameter.

Step 305: The MSC/VLR receives the registration response regnot, determines that the terminal has a service area service feature list, sends a QUALREQ, and requests the parameter.

Step 306: The HLR returns the service area service characteristic list parameter in the qualification response message qualreq according to the content in the qualification request message QUAL. The VLR is saved in the internal database; Step 307: The MSC/VLR returns the location update response to the BSC;

Step 308: The BSC registers the acceptance message with the MS.

As shown in FIG. 4, an example of a terminal voice call is described, wherein the processing of the MSC/VLR is the same for the circuit type data service call, the packet data service call, and the service channel short message call. Including the following steps:

Step 401: The mobile station MS initiates a call, and the BSC sends a service request to the MSC.

Step 402: The MSC/VLR obtains the service area identifier of the current location of the terminal according to the CI in the service request message, the personalized service area list registered by the user, and the correspondence between the service area and the CI configured by the MSC. Then, the service characteristics of the terminal in the service area are used to cover the corresponding items in the default profile data of the terminal, and the current profile data of the terminal is obtained. Temporarily save this specific profile data for use in this business process. The call permission of the current service is judged. If it is not allowed, the service is rejected, the call is released, and the calling mobile terminal is prompted in an appropriate form, such as a voice prompt, a short message prompt, and the like. In this example, the service is allowed to send an assignment request to the BSC;

Step 403: The BSC allocates resources such as an air traffic channel to the terminal, and completes the assignment to the MSC after completion;

Step 404: The MSC connects to the called party; Step 405: The called ringing, the PSTN (Public Switched Telephone Network) returns a ringing message to the MSC; Step 406: The called party picks up the answer;

Step 407: The calling party and the called user enter a call state. The serving MSC uses the specific profile data previously obtained and saved to control the subsequent service characteristics of the calling terminal.

Here, the interface between the VLR and the HLR is extended, and the HLR transmits the logical number of the service area to the VLR, and needs to correspond to a specific physical location in the MSC, that is, a group of cells. The number of CIs included in a service area needs to be determined based on actual conditions. An example of a configuration table for the correspondence between service areas and CIs used in step 402 of Figure 4 is as follows:

As shown in FIG. 5, an example of a terminal voice termination call is described, in which the processing of the MSC and the HLR part is the same for both the circuit type data service termination call and the service channel short message termination call. Including the following steps:

Step 501: A fixed telephone user calls the mobile terminal, and the PSTN (Public Switched Telephone Network) sends an initial address message IAM to the MSC;

Step 502: The MSC/VLR sends a location request to the terminal home location register HLR.

LOCREQ;

Step 503: The HLR determines that the terminal responds to the service MSC that sends the location request, and the back location responds to locreq;

Step 504: The MSC/VLR searches for information about the terminal in the local VLR database, and sends a paging request to the base station controller BSC.

Step 505: The BSC pages to the called terminal, and returns a paging response. Step 506: The MSC/VLR obtains the service area identifier of the current location of the terminal according to the CI in the paging response message, the personalized service area list registered by the user, and the correspondence between the service area and the CI configured by the MSC. Then, the service characteristics of the terminal in the service area are used to cover the corresponding items in the default profile data of the terminal, and the current profile data of the terminal is obtained. Temporarily save this specific profile data for use in this business process. The terminal call authority of the current service is judged. If it is not allowed, the service is rejected, the call is released, the prompt tone is played to the calling party, and the called mobile terminal is prompted in an appropriate form, for example, a short message prompt. In this example, the service is allowed, and the MSC sends an assignment request to the BSC;

Step 507: The BSC allocates related resources such as an air traffic channel to the terminal, and returns the assignment to the MSC.

Step 508: The MSC always returns the address full message ACM;

Step 509: The called terminal answers, and the BSC sends a connection message Connect to the MSC;

Step 510: The MSC returns a response message A]SM;

Step 511: The calling party and the called user enter a call state. The serving MSC uses the specific profile data previously obtained and saved to control the subsequent service characteristics of the called terminal.

As shown in Figure 6, the interaction between the MSC and the HLR is described when the terminal performs supplementary service operations. Including the following steps:

Step 601: The terminal performs a supplementary service operation, and the MSC/VLR obtains the service area identifier of the current location of the terminal according to the CI in the service request message, the personalized service area list registered by the user, and the correspondence between the service area and the CI configured by the MSC. . The MSC sends a FEATREQ (Feature Request) message to the HLR, carrying the service area identification parameter;

Step 602: The HLR determines, according to the operation in the FEATREQ (feature request), and the personalized service area service provided by the system to the user, whether to allow the user to modify the corresponding service feature in the service area list, and if so, modify the current service area of the user. Corresponding parameters in the list of service characteristics; No Bay I", modify the corresponding parameters in the default Profile data. HLR returns to featreq to MSC (feature response) message.
