Description

Roaming service processing method and device

[1] Technical field

[2] The present invention relates to the field of communications technologies, and in particular, to a roaming service processing method and apparatus.

[3] Background of the invention

[4] Roaming refers to a mobile terminal performing communication services in a non-attribute manner. With the development of communication services, roaming services are also receiving more and more attention. In some current networking, the processing of roaming services is not satisfactory.

[5] For example, the current NGN+WLL (Next Generation Network Ten Wireless Local Loop) networking, its networking mode can help fixed network operators to provide wireless services, reduce investment, and make full use of existing fixed network operators. Ground switched networks and existing rich services. However, since the access network and the core network are generally connected by V5, they are fixed users from the core network, so roaming cannot be achieved.

[6] For the above networking, a roaming method is currently proposed, which is used between the wireless access controllers on the access side.

The A3/A7 link is used to implement roaming, but this method has the following drawbacks:

[7] 1. Roaming is realized by the A3/A7 link between the radio access controllers, which requires a large number of circuitous circuits;

[8] 2. Unable to roam between wireless access controllers without A3/A7 interconnection;

[9] 3. The roaming/user service data needs to be queried across network elements, and the service data versions must be consistent.

[10] 4. Even if the versions are consistent, since the user service data is not in the roaming place, the user's supplementary service, intelligent service, Centrex (centralized user switch) service, etc. cannot be used after roaming.

In the mobile network, the mobile network BSC (Base Station Controller) and the MSC (Mobile Service Switching Center) pass through the A interface to support user roaming. The user data is stored in the HLR (Home Location Register), and after the user registers with the MSC, the user data is downloaded from the home HLR, and the user service completes control at the visited MSC.

Therefore, although the existing mobile network solves the roaming problem, the service triggering is in the roaming place, so the roaming softswitch needs to have all the user rights and service data of the user, which is complicated for the operation management, for example, the user a is in the soft exchange. A account, belonging to the A area, roaming to the B area under the jurisdiction of the softswitch B. If the user a wants to enjoy the same service in the softswitch B, the user must obtain the service authority and service data of the user a on the softswitch A, even if obtained. The data is also possible due to the version of Softswitch B and Softswitch A. Losing part of the business due to different ability.

[13] Summary of the invention

[14] The embodiment of the invention provides a roaming service processing method and device, which solves the problem of service loss existing in a roaming user terminal in the prior art.

[15] The embodiment of the present invention is implemented by the following technical solutions:

An embodiment of the present invention provides a method for processing a roaming service, including:

[17] determining the home softswitch of the roaming user terminal;

[18] triggering the service of the roaming user terminal to the home softswitch to trigger the home softswitch to process the service of the roaming user terminal according to user data and service authority of the roaming user terminal.

[19] The embodiment of the present invention provides a softswitch, including:

[20] a home softswitch determining module, configured to determine a home softswitch of the roaming user terminal;

[21] The softswitch interworking module is configured to trigger the service of the roaming user terminal to the softswitch to which it belongs.

[22] The embodiment of the present invention provides a softswitch, including:

[23] a service receiving module, configured to receive a service of a roaming user terminal;

[24] The service processing module is configured to determine user data and service authority of the user terminal according to the received service of the roaming user terminal, and process the service of the roaming user terminal according to the user data and service authority.

[25] It can be seen that the technical solution provided by the foregoing embodiment of the present invention can trigger the communication service of the roaming user terminal to be sent to the home softswitch, so that the user terminal can also enjoy the roaming state. All services that are vested in the softswitch avoid the loss of service caused by the user terminal in the roaming state.

[35] Mode for carrying out the invention

[36] The embodiment of the present invention improves the softswitch device, so that the user terminal performs the communication service in the roaming area, and the softswitch device in the roaming area can trigger the service to the soft exchange of the home location, so All services registered by the user terminal at the home location can be implemented in a roaming state.

[37] The embodiments of the present invention are not limited to softswitch devices, as long as devices implementing softswitch functions in other networks can be implemented. For example, softswitch devices in NGN+WLL networks, and MSC devices in mobile networks.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[39] An embodiment of the present invention implements the service processing of the roaming user terminal. As shown in FIG. 1 , a user terminal is assigned to the softswitch A, and the home softswitch A configures the account opening information for the user terminal. The softswitch B area, that is, the user terminal roaming soft switch is B, and the method for triggering the home service includes the following steps:

[40] Step 1: After the user terminal roams to the softswitch B area, the user terminal accesses the controller in the roaming place to perform the location registration service, and the roaming ground access controller updates the location through the extension with the softswitch B. The message informs the roaming softswitch B;

[41] First, the user terminal sends a location registration request message to the roaming access controller; the message includes an IMSI (Customer Identification Code) number of the user terminal;

[42] Then, the roaming access controller determines whether the user terminal has been registered according to the IMSI number of the user terminal, and if not, the access controller sends a registration request to the roaming softswitch, ie a location update request of the user terminal, where the request carries an IMSI number of the user terminal; if it is already registered, a corresponding response message is returned;

[43] Step 2: After receiving the registration request, the roaming softswitch B dynamically allocates a roaming physical number and a physical port resource to the user terminal, and determines the user terminal according to the IMSI number of the user terminal. a home softswitch, notifying the assigned roaming physical number to the home softswitch A of the user terminal;

[44] Step 3: The home softswitch A of the user terminal records the roaming status of the user terminal and the roaming And the softswitch exchanges the roaming physical number, and returns a response message to the roaming softswitch B; [45] the roaming softswitch B receives the response message, and returns a registration response to the access controller. [46] After receiving the registration response sent by the softswitch, the access controller returns a response to the user terminal that requests the registration, indicating that the location registration is successful.

[47] Step 4: subsequently routing the user terminal as the calling or called service to the home softswitch A of the user terminal;

[48] The roaming user terminal acts as a calling party, and the roaming softswitch B determines the home softswitch A of the user terminal according to the calling IMSI number segment, and then routes the call to its home softswitch A, where The home softswitch A processes the service according to the service authority of the user terminal;

[49] The roaming user terminal is called, and the softswitch according to the calling party determines the called home softswitch A according to the called logical number, and routes the call to its home softswitch A first. After the home softswitch A processes the authentication and other services, it is determined according to the roaming state of the user terminal that the user has roamed out, and then the roaming physical number is taken, and the user terminal is connected according to the service authority of the user terminal.

[50] The service authority of the user terminal is the service authority of the user terminal on the home softswitch, for example, whether the smart service includes prepaid, personalized ring back tone, etc., whether the cluster service is activated, or the like. If the user terminal has opened the service, and has the corresponding authority, the corresponding service is executed at the same time as the service execution. If the service is not activated, there is no such authority.

[51] Step 1-3 can be regarded as a maintenance step of the user location data in the roaming place and the home location, and step 4 can be regarded as a processing step of the call related to the user.

[52] The specific embodiment 1 provided below introduces a process in which a roaming mobile terminal acts as a calling party to trigger a home service. Before performing the following steps, the mobile terminal has established a connection with the roaming softswitch B. 2, including the following steps:

[53] Step 20: The mobile user terminal belonging to SoftX-A roams to SoftX-B, and the mobile terminal initiates a call in a roaming manner, and the softswitch of the roaming place is softswitch B (as shown in FIG. 2, hereinafter referred to as SoftX). -B);

[54] The call request message carries the calling IMSI, and the called number, and does not pay attention to whether the called party is a roaming user terminal;

[55] Step 21: After receiving the call request, the SoftX-B first determines whether it is the local number segment according to the calling IMSI, and if it is not the local office number segment, determines the home softswitch according to the calling IMSI number segment ( This implementation For example, the home softswitch A) is routed to the calling home softswitch A (as shown in Figure 2, hereinafter referred to as SoftX-A);

[56] Step 22: After the SoftX-A receives the call request message, if it determines that the IMSI is not the local number segment, the Bay IJ continues to route; if it is the local number segment, it searches for the SoftX-A to configure the calling terminal. The user data obtains the service authority and the logical number of the user terminal, and performs the call processing by using the logical number as the calling number according to the service authority.

[57] The foregoing embodiment 1 implements a process of the roaming user terminal as the calling party, and processes the call by routing the call to the home softswitch of the calling user terminal, so that the user terminal is at home. The services registered on the softswitch can be used in roaming, the rights and services of the user terminal are not lost, and centralized control of roaming authentication can be implemented.

[60] Since the calling terminal does not know whether the called terminal is roaming, its call is a logical number registered in the home softswitch, so the calling party first routes the call to its called home softswitch according to the logical number. , ie SoftX-A.

[61] Step 31: The home softswitch SoftX-A checks the user data of the user terminal A, and finds that the roaming status of A is roaming out (RFlag = OUT), and then obtains the roaming physical number A' of A. The called number, routes the call to the roaming softswitch, SoftX-B.

[62] Step 32: After receiving the call, the SoftX-B queries the user terminal of the softswitch to find that the user terminal is roaming (RFlag = IN), and obtains the user terminal. The registered access controller initiates a call to the access controller, and the access controller establishes a call after paging to the called user. After the call is established, a ringing (such as 180 message) and a response (such as 200 message) response are sent to the calling softswitch SoftX-A. [63] The foregoing embodiment 2 implements a process of the roaming user terminal as the called party, and processes the call by routing the call to the home softswitch of the called user terminal, so that the user terminal is at home. The services registered on the softswitch can be used in roaming, the rights and services of the user terminal are not lost, and centralized control of roaming authentication can be implemented.
