Description

TECHNICAL FIELD The present invention relates to the field of mobile communications technologies, and in particular, to a method, an apparatus, and a terminal for updating a service universal access network controller list. BACKGROUND OF THE INVENTION In a mobile communication network, an access network serves as a bridge between a mobile terminal user and a core network, and its communication capability directly affects the user experience. Based on the continuous development of short-range wireless communication technology and its advantages of high access bandwidth and low communication cost, access network technology has also developed the use of unauthorized mobile access (UMA, Unl icensed) based on short-range wireless communication technology. Mobi le Access) Generic Access Network (GAN) technology.

In the GAN network, the mobile terminal user first needs to establish a communication connection with the Generic Access Network Controller (GANC) through the Generic Access IP Network, and then the GANC and the core network. The Mobile Switching Center (MSC, Mobi le Switching Center) establishes communication. The above universal access IP network can provide a wireless access point for mobile terminals, and GANC is equivalent to an access network GERAN.

(GSM EDGE Radio Access Network) The base station subsystem (BSS, Base Station Subsystem) of the cell, that is, the MSC of the core network side has the same role as the BSS access network.

When the mobile terminal first accesses the GAN network, the mobile terminal will prepare the GANC according to the local storage.

(Provi sioning GANC ) information, initiates a discovery process to the corresponding Provisioning GANC, and obtains the default GANC (Default GANC) information from the Provisioning GANC, after which the mobile terminal initiates a registration process to the Default GANC. The registration initiated by the mobile terminal to the Default GANC can be divided into automatic registration and manual registration. The so-called automatic registration means that the mobile terminal registers with the corresponding GANC according to the obtained specified GANC or the specified PLMN (Public Land Mobile Network) associated with the GANC; Manual registration means that the mobile terminal acquires multiple GANC or PL information, and the mobile terminal selects a GANC to register, and notifies the registered manual mode (manual/user mode) to the GANC through a registration request message.

After determining a Default GANC, the process of automatic registration or manual registration of the mobile terminal to the Default GANC may be the same. Referring to FIG. 1, FIG. 1 is a process for a mobile terminal to initiate registration with a Default GANC. Figure. In the process, the mobile terminal sends a registration request (GA-RC Register Request) message to the Default GANC; after receiving the registration request message, the Default GANC returns a response message to the mobile terminal. The response message is specifically:

1. According to the actual situation, the Default GANC can accept the registration of the mobile terminal, and then return a registration-acceptance (GA-RC Register Accept) message to the mobile terminal, indicating that the mobile terminal is successfully registered;

2. The Default GANC may also reject the registration request of the mobile terminal and return a GA-RC Register Reject message to the mobile terminal;

3. Default GANC can redirect the registration request of the mobile terminal to other GANCs, and then return a GA-RC Register Redirect message to the mobile terminal.

If the Default GANC returns a registration accept or registration redirection message to the mobile terminal, the message carries a service GANC Table Indicator IEI, which is used to indicate whether the mobile terminal indicates whether the mobile terminal is The information of the GANC that has recently received the registration request of the mobile terminal needs to be stored locally, and the GANC of the registration request of the mobile terminal is said to be the service GANC, where the information of the service GANC is associated with the current location of the mobile terminal. The information of the serving GANC may include: an IP address of the serving GANC, or a domain name that can be used to find the IP address. See Table 1, which provides a schematic diagram of the structure of a service GANC list indicator.

Table 1

Among them, refer to Table 1. The specific indication can be carried by the parameter named SUTI named service GANC list. A description of the SUTI parameters can be found in Table 2:

Table 2 SUTI, Serving GANC table indicator indicator (octet 3)

Bitl

0 The MS is not allowed to store information in the stored Serving GANC table_"Do

Not Store".

1 The MS is allowed to store information in the stored Serving GANC table "Store". As can be seen from the contents of Table 2, the length of the SUTI parameter is one bit (bit), and if the indication value of the SUTI parameter is "0", it indicates "Do Not Store", that is, the mobile terminal is not allowed to save the information of the service GANC in the local service GANC list; if the indication value of the SUTI parameter is "1", it means "Store", that is, the mobile terminal is allowed to be in the service GANC list ( Serving GANC table ) holds the information of the service GANC.

The inventor found in the process of implementing the present invention, according to the existing service GANC list update scheme, wherein

1. If the SUTI parameter received by the mobile terminal carries the indication value "Store", the mobile terminal saves the indication value locally, and then saves the information of the serving GANC according to the indication value. The GANC may be Default GANC, or may be another GANC that can finally accept the registration request of the mobile terminal after one or more redirects, ie not a Default GANC;

2. If the mobile terminal receives the indication value of the identifier "Do Not Store" carried by the SUTI parameter, although the existing service GANC list update specification indicates that the indication value can be used to instruct the mobile terminal to update the service GANC list, How to update the service GANC list according to the indication of the indication value, the existing solution does not give a solution. Further, the indication value of the logo "Do Not Store" carried by the SUTI parameter did not function as it should. For example, after receiving the indication value of the identifier "Do Not Store", the mobile terminal does not perform any operation on the service GANC list; or, if the mobile terminal receives the indication value of the "Do Not Store", it is already local. Saved the logo

The indication value of "Store", the mobile terminal will still update the service GANC list according to the indication value of the previously saved identifier "Store", and will not execute the indication of the recently received indication value of the identifier "Do Not Store" .

Therefore, the existing implementation specification for the indication value of the identifier "Do Not Store" carried in the SUTI parameter in the update scheme of the service GANC list is not clear, and the update result of the mobile terminal to the local service GANC list update is not necessarily the GAN network. The expected update result, that is, does not necessarily meet the needs of the GAN network, and therefore, when the mobile terminal registers according to the information of the service GANC stored in the service GANC list, the registration failure may occur. SUMMARY OF THE INVENTION The embodiments of the present invention provide a method for updating a service universal access network controller list, so that the mobile terminal can update the local service GANC list to meet the requirements of the GAN network.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. A person skilled in the art may know that after the mobile terminal receives the indication value of the identifier "Do Not Store" carried by the SUTI parameter returned by the Default GANC, the operation expected by the indication value may not be performed. For example: The mobile terminal receives the registration redirection message sent by the Default GANC to the GANC A, and saves the indication value locally according to the indication value of the identifier "Store" carried by the SUTI parameter in the message. After the mobile terminal registers successfully on the GANC A, according to the saved indication value, the information of the service GANC A is saved in the local service GANC list, wherein if the local service GANC list is associated with the current location of the mobile terminal, the GANC If a message has been saved in the record of the information, the information of the service GANC A will overwrite the information of the previously stored GANC; if the record of the information of the GANC associated with the current location of the mobile terminal in the local service GANC list is empty, then The mobile terminal inserts the information of the registered service GANC into the related record of the service GANC list. Then, if the mobile terminal initiates manual registration, it needs to send a registration request to the Default GANC to obtain the information of the service GANC required for manual registration. After receiving the request, the Defaul t GANC carries the information of the GANC B in the registration redirection information, and Bringing the indication value of the identifier "Do not store" carried by the SUTI parameter to the mobile terminal, wherein the indication value indicates that the GAN network wants the mobile terminal not to save the information of the GANC B after the registration is successful; but because of the existing service GANC list The update specification does not give an indication of how to perform the "Do not store" indication. Therefore, the mobile terminal will still use the service GANC B that was successfully registered after the previous indication based on the previously stored identifier "store" (may also be provided by GANC B). The information of the GANC information associated with the current location of the mobile terminal in the information update list of the redirected GANC C), that is, the information of the GANC A is covered by the information of the GANC B (or GANC C), obviously, the operation of the overlay is Not what the GAN network expects.

For example, after the mobile terminal is redirected by the Default GANC, the registration is successful on a service GANC A in the roaming place, and the Defaul t GANC returns the indication value identifier "Store" in the SUTI parameter in the registration redirection message of the mobile terminal. The mobile terminal stores the information of GANC A in the relevant record of the local service GANC list.

If the mobile terminal re-registers with the Default GANC, in the case that the Default GANC wants the mobile terminal to be able to return to the home registration, the Default GANC will issue the registration acceptance of the SUT I parameter with the indication value "Do Not Store" to the mobile terminal. Or registering a redirect message. In this case, the GAN network actually expects the mobile terminal to delete the information of the GANC A saved in the local service GANC list.

However, since the existing related service GANC list update specification does not have an execution specification indicating that the mobile terminal deletes the content in the local service GANC list, the mobile terminal does not delete the original in the local service GANC list. If there is information, the next time the mobile terminal re-initiates the registration, it will still initiate registration with the GANC A referred to in the list, and the registration at the roaming location obviously does not meet the requirements of the GAN network.

In summary, the operation in the case of the foregoing example is not in accordance with the requirements of the GAN network. Therefore, in order to implement the update processing of the local service GANC list by the mobile terminal to meet the requirements of the GAN network, the embodiment of the present invention provides the general access of the update service. Network controller GANC list method,

Referring to FIG. 2, FIG. 2 is a flowchart of a method for updating a service GANC list in an embodiment of the present invention, where the process may include the following steps:

Step 201: The mobile terminal acquires an indication that the mobile terminal is not allowed to save the information of the serving GANC, and obtains an operation indication for the local service GANC list.

In this step, the indication that the mobile terminal does not allow the mobile terminal to save the information of the service GANC may be stored in advance in the local indication, or sent by the Default GANC to the mobile terminal during the registration process of the current mobile terminal to the Default GANC. After receiving the indication, the mobile terminal may save the indication locally, and if the local has saved an indication that the mobile terminal is allowed to save the information of the service GANC before receiving the indication, the currently received The indication overrides the indication that was originally saved locally.

In the embodiment of the present invention, in order to enable the mobile terminal to update the related records in the local service GANC list according to the requirements of the GAN network, after receiving the list update indication of the indication value such as the identifier "Do not store", the mobile terminal needs to move. The terminal responds to the received indication that the mobile terminal is not allowed to save the information of the service GANC, that is, according to the indication, the specific operation indication is obtained, and the corresponding operation may be performed according to the operation instruction.

Step 202: The mobile terminal processes the local service GANC list according to the foregoing operation indication.

In the embodiment of the present invention, the mobile terminal may use the indication obtained in the foregoing step 201 to perform corresponding processing on the information in the local GANC list according to the operation indication of the local GANC list further indicated in the indication, such as deleting or retaining the local The information of the GANC in the GANC list associated with the current location of the mobile terminal, etc., so that the mobile terminal can update the related records in the local GANC list to meet the requirements of the GAN network.

The indication of the information that does not allow the mobile terminal to save the service GANC, that is, the "Do not store" indication, may be carried by the indication value of the identifier "Do not store" carried by the SUTI parameter, how is the mobile terminal in the embodiment of the present invention Executing the received indication gives two implementations:

Solution 1: Modifying the service The GANC list indicates the cell tag. The Default GANC instructs the mobile terminal how to update the local service GANC list after receiving the "Do not store" indication.

Solution 2: The service GANC list indication cell tag is not modified, and the mobile terminal determines, according to the indication, how to update the local service GANC list; the following two implementation manners are described in detail: Option One

In the first scheme, the existing service GANC list indication cell marker is extended. Referring to Table 3, Table 3 is a structure of a service GANC list indicating cell tag in the embodiment of the present invention.

table 3

As can be seen from Table 3, a parameter named DNSI (Do not store indicator) is added in the first scheme, and the DNSI parameter further gives an operation indication to the execution of the indication value of the identifier "Do Not Store" in the SUTI parameter. Among them, the definition of DNSI parameters can be found in Table 4. Table 4

DNSI, Do not store indicator (octet 3)

0 The MS should delete al l the related information in the table.

1 The MS should not store the new successful ly registered GANC information and maintain the old information in the table.

As shown in Table 4, the length of the indication value of the DNSI parameter may be lbit. If the indication value of the DNSI parameter is set to “0”, it may be used to indicate that the mobile terminal deletes the local service GANC list and is related to the current location of the mobile terminal. The information of the associated GANC can be used to indicate that the entire GANC list is cleared. The setting of the DNSI parameter with the indication value of "1" can be used to indicate that the mobile terminal does not store the information of the GANC corresponding to the last successful registration. That is, the information of the service GANC is not saved, and the original information in the service GANC list can be retained.

Further, referring to Table 5, the definition of the indication value with respect to the DNSI parameter can be set according to actual needs. For example, the length of the indication value of the DNSI parameter can be set to multiple bits, and the operations corresponding to each bi t value are respectively defined. Instructing, for example, that the bit value indicates that the mobile terminal does not store the information of the GANC corresponding to the last registration success, and the bit2 value may be used to delete the information of the GANC associated with the current location of the mobile terminal in the local service GANC list, which may be indicated by the bit3 value. Empty the entire GANC list and more.

Further, referring to Table 6, the corresponding indication information may also be represented by a plurality of b it, for example: When setting the DNSI parameter with the indication value of "01", And the information may be used to indicate that the mobile terminal deletes the information about the GANC associated with the current location of the mobile terminal in the local service GANC list. When the setting of the DNSI parameter with the indication value is “10”, the mobile terminal may be used to indicate that the entire GANC list is cleared. If the indication value of the DNSI parameter is "00", it can be used to indicate that the mobile terminal does not store the information of the GANC corresponding to the last successful registration.

The following is a detailed description of how the mobile terminal in the first scheme operates the GANC list update indication received in the first scheme. For details, see the following:

Referring to FIG. 3, FIG. 3 is a flowchart of updating a service GANC list in an embodiment of the present invention. The process can include the following steps:

Step 301: The mobile terminal sends a registration request message to the Defaul t GANC.

Step 302: The Default GANC returns a response message carrying the service GANC list update indication to the mobile terminal. The response message of the carry service GANC list update indication may be a registration accept message or a registration redirect message. The list update indication may be carried by an indication value carried by the SUTI parameter, such as an indication value indicating "Store". Or identify the value of "Do not store":

Wherein, if the list update indication is carried by the indication value of the identifier "Do not store" carried by the SUTI parameter, the service GANC list indicates that the operation indication of the indication value of the "Do not store" is further indicated in the cell marker. The operation indication is carried by the indication value carried by the DNSI parameter.

Step 303: After receiving the response message returned by the Default GANC, the mobile terminal locally saves the list update indication in the response message.

For the first scheme, in the original case, after receiving the indication value of the identifier "Do not store" carried by the SUTI parameter, the mobile terminal does not perform any processing according to the indication of the indication value. In the first scheme, regardless of whether the list update indication is carried by the indication value of the identifier "Store" carried by the SUTI parameter, or by the update indication value of the identifier "Do not store" carried by the SUTI parameter, the mobile terminal saves the location. The received list update indication, that is, the related indication value, and the mobile terminal replaces the previously saved indication value with the currently received indication value, and further, the mobile terminal can determine how to perform the service GANC list according to the saved indication value. operating.

Step 304: After the registration is successful, the mobile terminal performs corresponding update processing on the local service GANC list according to the locally saved list update indication.

If the message received by the mobile terminal is the registration accept message sent by the service Default GANC, if the Default GANC gives the indication value "Store" with the SUTI parameter, the service GANC list indicates the cell tag, and the DNSI parameter is included. The indication value may be empty, or the value carried is meaningless. The mobile terminal stores the indication value of the SUTI parameter, and stores the information of the service GANC with the location information of the current mobile terminal, such as the cell identifier or the access point identifier. Into the service GANC list.

If the message received by the mobile terminal is a registration redirection message sent by the Default GANC, and the SUTI parameter carries the indication value "Store" in the message, the service GANC list indicates the cell tag, and the indication value of the DNSI parameter is also The mobile terminal may store the indication value of the SUTI parameter, and the mobile terminal initiates a registration request to the redirecting GANC according to the information of the redirected GANC carried in the message, wherein if the registration is successful, the mobile terminal may With the redirected GANC as the serving GANC, the information of the service GANC is saved to a record of the information of the GANC associated with the current location of the mobile terminal in the local service GANC list.

If the mobile terminal has successfully left the GAN network after registration, the registration is initiated after the GAN network is re-entered. The registration accept message received by the mobile terminal is from the non-Default GANC, and the mobile terminal can set the service corresponding to the successful registration according to the indication value of the identifier "store" carried by the SUTI parameter stored in the last registration success. GANC information is stored in the relevant records of the local service GANC list.

If the mobile terminal has previously successfully registered through the GANC A, and the local service GANC list is currently associated with the mobile terminal The information of the GANC A is stored in the record of the information of the GANC associated with the location. The registration is a manual registration initiated by the mobile terminal, and the list update indication received by the mobile terminal is carried by the registration redirection message returned by the Default GANC. If the list update indicates "Do not store", the service GANC list indication letter is sent. In the meta tag, the SUTI parameter carries the indication value "Do not store", and the indication value of the DNSI parameter may be "1", that is, the mobile terminal is instructed to retain the information in the local service GANC list. It is assumed that the redirected GANC returned by the Default GANC is GANC B, and the mobile terminal successfully registers with the GANC B. After the mobile terminal obtains the indication value of the DNSI parameter, the operation instruction given according to the indication value does not store the GANC B. The information retains the information of GANC A stored in the local service GANC list.

If the mobile terminal has previously successfully registered through the GANC A of the roaming place, and the currently stored SUTI parameter carries the indication value "Store". In the case that the mobile terminal has the opportunity to re-register with the Default GANC, the Default GANC wants the mobile terminal to register with the home network, and the Default GANC brings the indication value of the identifier "Do not Store" carried by the SUTI parameter to the mobile terminal, which is implemented by the present invention. In the example, the service GANC list indicates that the indication value "0" of the DNSI parameter is further given in the cell tag. After the mobile terminal obtains the indication value of the DNSI parameter, the operation instruction given according to the indication value is saved. The information of the GANC associated with the location of the mobile terminal in the local service GANC list, that is, the information of the GANC A is deleted, so that the Default GANC can bring the information of the local GANC to the mobile terminal, and can instruct the mobile terminal to store the local GANC. Information, when the mobile terminal initiates registration next time, it is preferred to register on the home network, which can effectively guarantee the registration success rate of the mobile terminal. Or if the parameter indicates that the entire service list is cleared, the mobile terminal deletes all the information in the table.

It can be seen that the scheme further gives an execution specification about the "Do not store" indication, so the mobile terminal can correctly perform the information given by the GAN network on how to update the GANC associated with the location of the mobile terminal on the local service GANC list. The indication, in response to the GAN network, relates to the related requirements of the information of the GANC associated with the location of the mobile terminal in the update service GANC list, and accordingly, the mobile terminal registration success rate can be improved. Option II

For this solution, it is not necessary to extend the service GANC list cell tag, but after the mobile terminal receives the indication value of the identifier "Do not store" carried by the SUTI parameter sent by the Default GANC, according to "Do not store" Indicates that the instruction is executed instead of not processing the indication.

For the solution, the process of updating the GANC list can also be seen in the process shown in Figure 3. The difference from the specific implementation description of each step in scenario 1 is:

After receiving the "Do not store" indication, the mobile terminal can use the GANC that can sense the current registration success. The GANC of the home network is also the GANC of the roaming network to determine whether to keep the record of the information of the GANC associated with the current location of the mobile terminal in the local service GANC list, or to delete the record, for example, it can be set as:

If the current service GANC perceived by the mobile terminal is not the GANC of the home network, after receiving the "Do not store" indication, it may be learned that the information of the GANC associated with the current location of the mobile terminal in the local service GANC list needs to be deleted. The recorded operation instruction, according to the operation instruction, deletes the corresponding record, and when the mobile terminal initiates the registration of the GAN network again, it is found that the relevant record in the local service GANC list is empty, and the registration can be initiated to Defaul t GANC;

If the current service GANC perceived by the mobile terminal is the GANC of the home network, after receiving the "Do not store" indication, it may be known that the information of the GANC associated with the current location of the mobile terminal in the local service GANC list needs to be retained. The recorded operation indication, according to the operation instruction, retains the corresponding record, then the next time the mobile terminal needs to register to the GAN network, the registration is initiated from the GANC recorded on the local service GANC list.

Therefore, accordingly, the behavior of the mobile terminal initiating registration with the local GANC is also desirable by the GAN network, i.e., in compliance with the requirements of the GAN network.

Under the scheme, in order to implement the operation instruction corresponding to the indication according to the received "Do not store" indication, the mobile terminal can reach a relevant consensus between the operator and the equipment provider, and then perform corresponding on the mobile terminal side. Deploying, if the mobile terminal is configured to receive the "Do not store" indication, the operation indication for further performing the indication may be that the information of the registered GANC is not saved, and the GANC of the local service GANC list associated with the current location of the mobile terminal is reserved. Recording of the information; or deleting the record of the information of the GANC associated with the current location of the mobile terminal in the local service GANC list; or deleting the record of the information of all the GANCs in the local service GANC list. In addition, in the embodiment of the present invention, The mobile terminal receives the registration rejection message, which can be similar to the existing related processing, that is, if the rejection message is from the Default GANC, the mobile terminal needs to initiate the discovery process, and select Defaul t GANC to register; if the rejection message comes from non-Default GANC, then, if the mobile terminal is repeatedly Non-Defaul t GANC rejected, the mobile terminal will take the initiative to save the local GANC list of services and current information of the mobile terminal non-Default GANC associated with the location of deleting, after the re-registration process initiated by the original Default GANC.
