As more and more mobile users cross-regional communication, operators in order to win customer satisfaction, correspondingly provide a richer means of business implementation, so that customers can experience more service content.

Currently, if a roaming user wants to obtain a service consistent with a local user in the roaming network, the user needs to go to the home network to open the corresponding service. If the home network does not support the service, the roaming user cannot enjoy the service. In addition, if the roaming user opens a certain service on the home network, the roaming network also activates the service, but the content of the service is more abundant in the roaming network, then, if the roaming user wants to enjoy the service in the roaming network All the services provided need to be supported by the home network. If the home network is not supported, the roaming users cannot enjoy the richer service of the content in the roaming network.

The following is a detailed description of the Global System for Mobile Communications (GSM) network: After the user roams to the new network, the location update process will be initiated. Figure 1 is a schematic diagram of a location update process in an existing GSM network. As shown in Figure 1, the following steps are included:

Step 101: The roaming network sends a location update request message to the signaling transfer point (STP, Signaling Transfer Point), where the location update request message carries the international mobile subscriber identity (IMSI, International Mobile Subscriber Identity) and other information.

Step 102 ~ Step 103: The STP sends the location update request message to the home location register (HLR, Home Location Register) in the home network through the intermediate signaling transfer device.

Steps 104 to 106: The home network HLR responds to the received location update request message, and sends an insert user data message to the roaming network through the intermediate signaling switching device and the STP. The inserted user data message carries the subscriber's subscription service on the home network. And other information.

Steps 107 to 109: The roaming network sends back an insert user data response message to the home network HLR through the STP and the intermediate signaling switching device.

Step 110 ~ Step 112: The home network HLR sends a location update response message to the roaming network through the intermediate signaling switching device and the STP.

During the location update process, if the user carried in the inserted user data message returned to the roaming network does not include some services in the roaming network where the user is currently located, or some service content is not as roaming.

The update in the above signaling device 202 includes operations such as adding, deleting, modifying, and mapping. For details on how to implement these operations, refer to the description of the corresponding part of the method.

In addition to appearing as a separate device in the system, the signaling device 202 may also be a combination of a signaling switching device and a signaling processing device, as shown in FIG. 4, FIG. 4 is a second implementation of the system of the present invention. Schematic diagram of the structure of the example. The difference between the embodiment and the first embodiment is that the function performed by the signaling device 202 in the first embodiment is implemented by the signaling switching device 401 and the signaling processing device 402 in this embodiment:

The signaling switching device 401 is configured to receive and forward the service information from the home network HLR 203 to the signaling processing device 402, and send the updated service information returned by the signaling processing device 402 to the roaming network service executing device 201;

In this embodiment, the update in the signaling processing device 402 includes operations such as adding, deleting, modifying, and mapping. For details on how to implement these operations, refer to the description of the corresponding part of the method. The signaling switching device in this embodiment is STP; the signaling processing device is SPS. In an actual application, in addition to the STP and the SPS, the foregoing signaling device may further include an intermediate signaling switching device, where the device is located between the STP and the home network HLR in the system, and the function is consistent with the prior art.

Based on the systems and devices described above, in the method embodiments of the present invention:

The signaling device updates the received service information according to the preset update request for updating the user service information to achieve the configuration of the roaming network service, and sends the updated service information to the roaming network.

Wherein, when the signaling device is composed of a signaling switching device and a signaling processing device, the specific implementation process of the method is:

The signaling switching device first forwards the received service information to the signaling processing device; the signaling processing device updates the service information according to a preset update request for updating the user service information to achieve the same configuration as the roaming network service configuration. And sending the updated service information to the signaling transfer device; the signaling transfer device sends the updated service information to the roaming network.

Before the signaling device updates the received service information according to the update request, it further includes:

The roaming network requests service information from the home network HLR through the signaling device, and the home network HLR sends back service information to the signaling device.

The service information is the subscription service information of the user in the home network, and the method for the roaming network to request the service information from the HLR through the signaling device is: the roaming network sends the location update or route routing (SRI, Send Routing Info) to the HLR through the signaling device. Correspondingly, the home network HLR returns the subscription service information of the user in the home network to the signaling device in a message such as the inserted user data or the route response (SRI_Ack).

The updating includes adding, deleting, and deleting the subscription service information of the user on the home network. Modify or map operations.

The pre-set update request mentioned in the embodiment of the present invention refers to a service update request that the user performs a service request to the operator in advance, and the operator sets the signaling device according to the user requirement. For example, if a user wants to roam from Shanghai to Beijing, the user will apply for roaming service to the operator in advance, and the operator knows the subscription service status of the user on the home network and the service provision of the roaming network according to the information such as the user terminal number, and According to the difference between the two, the signaling device, such as the SPS, is set up to update the user service information to achieve the update requirement consistent with the roaming network service configuration. After receiving the service information of the user, the subsequent SPS adds, deletes, or modifies the service information according to the update request, or uses the mapping relationship between the home network and the roaming network service attribute in the update request to convert the subscription service of the user in the home network. Attributes.

For example, if the roaming network is enabled with the CRBT service and the home network is not enabled, the roaming user needs to pre-require the roaming network operator to open the CRBT service for the roaming service. Configure the subscription attributes of the CRBT service on the SPS device. This way, when the user roams to the roaming network:

The roaming network sends an SRI message to the user home network HLR through the SPS. When the SRI message passes the SPS, the SPS queries whether the subscription attribute of the roaming network CRBT service is pre-configured in the local database, and if the CRBT service is configured on the SPS. The contract attribute, the SPS records the transaction identifier (TID, Transaction ID) of the session message, and forwards the message to the home network HLR;

After receiving the SRI message, the home network sends back an SRI_Ack message to the roaming network through the SPS. The T_CSI field of the SRI_Ack message carries the subscription service information of the user on the home network.

When the SRI_Ack message passes through the SPS device, the SPS inserts the subscription attribute of the CRBT service on the T_CSI field of the SRI_Ack message according to the recorded TID information. After receiving the SRI_Ack message of the CRBT service subscription attribute, the roaming network analyzes the subscription attribute of the CRBT service, and triggers the related process of the CRBT service according to the subscription attribute. The related process of how the roaming network triggers the CRBT service is the existing technology, which is not described in detail here.

What is described above is an example in which the SPS inserts user service information in the T_CSI field of the SRI_Ack message. Similarly, when the service attribute of the user needs to be changed from A to B, the SPS device can replace the T_CSI field in the SRI_Ack message; or, when the service information of the user needs to be deleted, the SPS device can use the T_CSI field of the SRI_Ack message. Delete it.

It should be noted that the scope of application of the present invention is a mobile network capable of providing a function of inserting user data. The process of updating the subscription service information of the user in the home network may be completed in the process of taking the route, or may be completed in the process of updating the location of the roaming network and the home network HLR, as long as the information returned by the home network HLR is allowed. Just insert the data.

The following is a detailed description of the technical solution of the present invention by taking the location update process in the mobile network GSM as an example. Figure 5 is a flow chart of an embodiment of a method of the present invention. In this embodiment, the signaling device is composed of three parts: an STP, an SPS, and an intermediate signaling switching device. As shown in Figure 5, the following steps are included:

Step 501: The user roams to the new network, initiates a location update process, and the location update request message is sent by the roaming network to the STP. The location update request message carries the IMSI and other information steps 502-503: The STP will pass the intermediate signaling transfer device. The location update request message is forwarded to the home network HLR.

Steps 504 ~ 505: After receiving the location update request message, the home network HLR responds by inserting a user data message to the STP through the intermediate signaling switching device; inserting the user data message Carrying information such as the contracted service of the user on the home network.

Step 506: The STP forwards the received insert user data message to the SPS.

Step 507: The SPS updates the subscription service of the home network carried in the user data insertion message according to the preset update request, and sends the updated inserted user data message to the STP.

When the user inserts the user data message through the SPS, since the update request has been set in advance, the SPS automatically updates the subscription service information of the user in the home network that is carried in the inserted user data message, and the update includes adding some kind of The service information, the deletion of a certain service information, or the modification of the existing service information, or the mapping service attribute of the user in the home network from the original A according to the mapping relationship between the home network and the roaming network service attribute in the update request on the SPS , converted to B that meets the user's current roaming network service configuration.

Step 508: The STP sends the updated inserted user data message to the roaming network. Steps 509 ~ 511: The roaming network sends back an insert user data response message to the home network HLR through the STP and the intermediate signaling switching device.

Steps 512 ~ 514: The home network HLR sends a location update response message to the roaming network through the intermediate signaling switching device and the STP.

At this point, the location update process ends, and the roaming network can trigger the relevant network element according to the updated user subscription service information, and execute the corresponding service.

It can be seen that, by adopting the technical solution of the embodiment of the present invention, a signaling device with updated user subscription service information is introduced in the system, and the signaling device can update the user subscription service attribute or perform service supplement according to the user requirement; thus, the roaming network is configured according to The updated subscription service information can trigger the relevant network element to provide the corresponding service service for the roaming user, so that the roaming user enjoys the same service as the local user in the roaming network; Moreover, the existing user is not required to implement the above process. The home network and the devices of the roaming network make any changes, which are convenient and convenient. In conclusion, the above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
