Description

Automatic numbering method and system, user equipment

The invention relates to an automatic numbering technology based on over-the-air technology (OTA), in particular to a method and system for automatically placing numbers, and a user equipment. Background technique

For user equipment (UE, User Equipment), the UE parameters are usually written by OTA technology. However, the general OTA technology needs to introduce Customer Service Center (CSC) and Over the Air Service Provisioning Function (OTAF). The network investment is large, and the current network transformation data is more, which is not convenient for operators to deploy quickly. And commercial, also increased the cost of operator equipment maintenance.

Figure 1 shows the flow chart of the standard OTA air port numbering. As shown in Figure 1, the traditional OTA numbering process includes the following steps:

Step 101: The UE user dials an OTA service activation code (such as *228) by using the UE that needs to burn the number, and the Mobile Switching Center (MSCe, Mobile Switching Center) connects the OTA call to the CSC.

Step 102: The CSC instructs the UE user to input the MDN number that needs to be burned this time. The mobile identification number (MIN, Mobile Identification Number) corresponding to the number has been preset in the OTAF or randomly assigned by the OTAF; and the OTA service. Activate the password.

Step 103: After receiving the mobile subscriber directory number (MDN, Mobile Directory Number) and the OTA service activation password, the CSC sends the OTAF to the OTAF through the internal Connect interface, and instructs the OTAF to attach to the MSCe to establish a connection with the MSCe.

Step 104: After the MSCe successfully establishes a connection with the OTAF, the CSC instructs the OTAF to generate an authentication code (Akey) of the UE.

Step 105, the OTAF notifies the HLRe to generate an AKey, and the HLRe and the UE perform parameters (generating Akey's public key information is exchanged, and Akey is generated on both the UE and HLRe sides using the Diffie-Hdlman algorithm.

Step 106: After the Akey is generated, the CSC notifies the OTAF to update the shared secret data (SSD, Shared Secret Data) of the UE. OTAF Trigger HLRe starts SSD updates.

Step 107: After the SSD update is completed, the CSC notifies the OTAF to start downloading parameters to the UE. The OTAF writes the assigned MIN to the UE through the air interface, and also writes other parameters such as the NAM (Number Assignment Module) and the preferred roaming list (PRL) to the UE through the air interface.

Step 108, the OTAF finally informs HLRe to submit the AKey, and the HLRe automatically generates an authentication record (including Akey, Electronic Serial Number, etc.) about the MIN. The MDN selected by the associated UE user can be automatically implemented, and the UE is given a fixed subscription service.

The traditional OTA numbering method has the following disadvantages: It is necessary to introduce OTAF and CSC network elements at the same time, and the network investment is large; the air port number cannot automatically sign the featured service; the current network needs to be transformed, and the equipment maintenance cost is also large.

The invention enables the MSCe and the HLRe to implement the functions of the CSC and the OTAF respectively by upgrading the existing network MSCe (selecting one of the gateways or the end office for upgrading) and the HLRe software version. After the upgrade, MSCe replaces CSC to complete the collection of burn-related information. The upgraded HLRe has the function of OTAF. Hereinafter, for convenience of description, the CSC-capable MSCe is referred to as MSCe/CSC, and the OTA-capable HLRe is referred to as HLRe/OTAF.

After the user initiates an OTA call, it will first connect to the MSCe/CSC. The MSCe/CSC collects the information related to the user input, and sends the information related to the burning number to the HLRe/OTAF through the Mobile Application Part (MAP) message. . HLRe/OTAF automatically triggers the OTA air port numbering process and automatically sets the user subscription information. In the present invention, MSCe And MSC refers to the mobile switching center, and both HLRe and HLR refer to the home location register.

2 is a flow chart of a method for automatically placing a number according to the present invention. As shown in FIG. 2, the method for automatically numbering the present invention includes the following steps:

Step 201: The UE user dials an OTA service activation code (such as *228) by using the UE that needs to burn the number, and the MSCe connects the call to the upgraded MSCe/CSC office.

Step 202: The MSCe/CSC instructs the UE user to input information about the current burning number, such as the MDN number to be fired, the OTAF service activation password, and the like. The MDN number and the OTAF service activation password are carried by the UE and are allocated to the UE by the UE manufacturer.

Step 203: In order to implement the automatic account opening and the special service subscription, the MSCe/CSC puts the subscription service introduction tone to the UE user, and prompts the UE user to select the corresponding subscription package service. For example, the UE is notified to select the corresponding subscription service according to the corresponding keyboard on the UE, for example, the key "1" represents the online service.

Step 204: After collecting the information related to the burning number, the MSCe/CSC sends the information to the HLRe/OTAF through the extended interface between the MSCe and the HLRe.

Step 205, the HLRe/OTAF is automatically attached to the MSCe to establish a connection with the MSCe. Step 206: After the connection between the HLRe/OTAF and the MSCe is established, the Diffie-Hellman algorithm is used to generate the Akey related parameters through the air interface exchange with the UE, and the Akey is generated in the HLRe/OTAF and the UE respectively.

Step 207: After the Akey is generated, the HLRe/OTAF triggers an SSD update.

Step 208: After the SSD is successfully updated, the HLRe/OTAF randomly generates an unused MIN number for the OTA service, and notifies the UE to the MIN, so that the UE can write the MIN by itself, and can also notify the UE to write other parameters. Such as NAM, PRL and other parameters.

Step 209, HLRe/OTAF automatically submits Akey to the network, and automatically saves the file in the database. The MIN, Akey, and ESN parameters of the UE are written.

Step 210: The HLRe/OTAF automatically associates the MIN-MDN with the subscription package ID selected by the UE, and implements automatic account opening and signing of the special service.

FIG. 3 is a flowchart of Akey automatic update of a UE according to the present invention. As shown in FIG. 3, the Akey automatic update process of the UE of the present invention includes the following steps:

Step 301: The operator initiates an operation of updating the Akey for a specific UE, and the HLRe/OTAF automatically triggers an indication of updating the Akey.

Step 302: The HLRe/OTAF uses the Diffie-Hdlman algorithm to generate an Akey public key information parameter through the air interface exchange with the UE, and generates an Akey in the HLRe/OTAF and the UE.

Specifically, the exchange of the Akey public key information is performed between the HLRe/OTAF and the UE;

Each of the HLRe/OTAF and the UE generates a private key for generating Akey, and generates an Akey based on the Diffie-Hdlman algorithm using the public key that generates the Akey. In this way, the Akey generated by each of HLRe/OTAF and UE is the same.

Step 303: After the Akey is generated, the HLRe/OTAF triggers an SSD update.

Step 304, HLRe/OTAF completes the SSD update operation.

Step 305, HLRe/OTAF automatically submits Akey, and automatically saves the updated Akey parameter in its database.

Step 306, the HLRe/OTAF constructs a short message (SMDPP, short message Deliver Point to Point) short message to notify the UE user that the Akey update is successful.

4 is a flow chart of IMSI automatic update of a UE according to the present invention, as shown in FIG.

The UE's IMSI automatic update process includes the following steps:

Step 401: The operator initiates an operation of updating the IMSI for a specific UE, and the HLRe/OTAF automatically triggers the indication of updating the IMSI.

Step 402: The HLRe/OTAF automatically triggers an OTAPA (Over the Air Parameter Administration) operation. Step 403: The HLRe/OTAF notifies the UE to write a new IMSI parameter by using an air interface.

Step 404, HLRe/OTAF automatically triggers the SSD update operation.

Step 405, HLRe/OTAF uses the new IMSI for SSD update operation.

Step 406: After the SSD is successfully updated, the HLRe/OTAF automatically performs a card replacement operation.

Step 407: The HLRe/OTAF constructs an SMDPP short message to notify the UE user that the IMSI update is successful.
