Description

Method for acquiring update capability information of mobile terminal

technical field

The present invention relates to a method for obtaining update capability information of a mobile terminal, in particular to a method for obtaining update capability information of a mobile terminal and updating the information recorded in the capability information database of the mobile terminal on the network side after the mobile terminal newly installs or deletes certain installed software. The capability information of the mobile terminal and the method for correspondingly processing the service requested by the mobile terminal at the same time.

Background technique

With the development of mobile communication technologies, mobile networks gradually provide users with various services. At present, many network devices perform corresponding service operations according to terminal capabilities. With the continuous development of mobile terminal technology, open operating systems/platforms have been used more and more. The so-called openness means that the operating system/platform opens the programming interface API to third parties, so that a large number of third-party software can be installed on the terminal, thereby adding terminal functions and enjoying more services. In the prior art, the network obtains the terminal capability mainly through the method that the user dials a specific phone number or logs in to a specified web page to actively register, uses the user profile provided by the wireless application protocol, or reports the International Mobile Equipment Identity, but these three The way for the network side to obtain the user terminal capability information is a static method, and it is impossible to know the dynamic information of the user terminal capability. That is to say, when the terminal capability increases or decreases due to the installation or deletion of programs, the network side only knows It is impossible to know the terminal capability changes caused by the user's personal behavior after leaving the factory, which will cause the network side to be unable to provide users with services that are more suitable for the terminal capabilities. Therefore, in this way, services on the network side and the terminal side cannot be adapted, and users cannot obtain corresponding services in a timely and correct manner.

A method for updating user terminal capability information is disclosed in the document whose application number is 03149551.6. Compared with the above three methods commonly used in the prior art, it overcomes the shortcomings of the static mode of obtaining mobile terminal capability information on the network side. However, in this document, the user terminal capability update request is initiated by the user. When the network side considers it unnecessary to initiate an update request, if the user initiates the initiative, it will cause an additional burden on the network; and when the network decides that it is necessary to update the user terminal function Sometimes, it is impossible to take effective means to obtain terminal capability information.

In addition, there is also a method for dynamically acquiring the capabilities of a mobile terminal. This method adds a detection module to the terminal to detect information about the capability update caused by the newly installed software to the mobile terminal when the terminal installs new software. When the service requested by the terminal When it does not match the factory capability of the terminal, at the request of the network side, the terminal reports its update capability information. This method overcomes the shortcomings of any of the above-mentioned methods for obtaining user terminal capability information on the network side, but each time the service requested by the terminal does not match its factory capability, it must report its update capability information, resulting in the same update capability information Repeated reporting also increases the network burden.

Contents of the invention

The purpose of the present invention is to provide a method for obtaining update capability information of a mobile terminal in order to provide a method for obtaining update capability information of a mobile terminal, which enables the network side to According to their own needs, the update capability information of the mobile terminal after installing new software or deleting a certain installed software can be obtained, and the capability information of the mobile terminal recorded in the network side database can be updated in time according to the update capability information, and at the same time, according to the updated mobile terminal Capability information for corresponding business processing.

In order to achieve the above object, the present invention provides a method for obtaining update capability information of a mobile terminal, comprising the following steps:

Step 1. The mobile terminal initiates service request information to the network side, and the service request information carries a field identifying the latest capability information of the mobile terminal;

Step 2. The network side queries the capability information of the mobile terminal recorded in the database according to the received service request information, and judges whether the capability of the mobile terminal is consistent with the capability requested by the mobile terminal according to the capability information. The business matches, if not, go to step 3; if they match, go to step 7;

Step 3. The network side compares whether the field is the same as the field identifying the mobile terminal capability information in the database, if not, perform step 4; if they are the same, skip to step 8;

Step 4. The network side sends signaling to the mobile terminal, requiring the mobile terminal to report update capability information;

Step 5. The mobile terminal reports the update capability information to the network side;

Step 6. The network side updates the capability information of the mobile terminal in the database according to the update capability information; at the same time, the network side judges whether the capability corresponding to the update capability information matches the service , if it matches, go to step 7; otherwise, go to step 8;

Step 7. The network side processes the service requested by the mobile terminal, and then jumps to step 9;

Step 8. The network side does not process the service requested by the mobile terminal, and sends a prompt message not to process to the mobile terminal;

Step 9. End.

In the above-mentioned method for obtaining update capability information of a mobile terminal, a detection module is added to the mobile terminal before the step 1, and the detection module is used to detect when the mobile terminal is installing or deleting software. The process is:

When the mobile terminal installs new software, the detection module detects that the mobile terminal has new software installed, and the newly installed software provides the detection module with the update capability caused by the newly installed software to the mobile terminal information, or the update capability information caused by the newly installed software to the mobile terminal is recorded by the detection module; when the mobile terminal deletes the software installed after leaving the factory, the detection module detects that the mobile terminal has software deleted, then all the software installed after leaving the factory but not deleted will provide the detection module with the update capability information caused by the undeleted software to the mobile terminal, or the detection module will record the impact of the undeleted software on the mobile terminal. The update capability information caused by the mobile terminal; the detection module updates the capability description (User Agent) field of the mobile terminal according to the update capability information caused by the newly installed software or the undeleted software to the mobile terminal.

When the detection module updates the User Agent field, a field representing the information of the newly installed software is added on the basis of the original User Agent field, or a field is added on the basis of the original User Agent field. An encoding corresponding to the updated User Agent field, used to identify updates to said User Agent field.

In the step 1, the field carrying the latest capability information identifying the mobile terminal is the User Agent field carrying the latest capability information identifying the mobile terminal.

When the mobile terminal deletes the software installed after leaving the factory, the UserAgent field of the mobile terminal is restored to the field set at the factory.

It can be seen from the above technical solutions that in the present invention, the mobile terminal saves the information related to the capability update of the mobile terminal after installing or deleting the software, and reports it when needed on the network side. Compared with the mobile terminal actively reporting the update capability information, it reduces the Network overhead: the network side updates the capability information of the mobile terminal recorded in the database in a timely manner according to the update capability information reported by the mobile terminal. If the User Agent field reported by the mobile terminal is the same as the User Agent of the mobile terminal recorded in the database, it is not required The mobile terminal reports its capability information again, which avoids the problem of the mobile terminal repeatedly reporting and updating the capability information, further reduces the network load, speeds up the service processing process, and improves the service processing efficiency.
