EV-DO system for updating terminal parameter through midair port and implementing method thereof

Abstract

The invention discloses an EV-DO system of updating terminal parameters through an air interface and a realization method thereof, which belongs to a CDMA20001x wireless high-speed grouped data (EV-DO) communication system. The method of the invention is to set an air load OTA center which is connected with an AAA sever of authentication, entitlement and charging and used for launching, stopping or configuring air load operation in a core network; according to the user information reported by the AAA server, the OTA center sends the updated information carried with updated contents to a user terminal that needs updating through the air interface; the operation of updating the terminal parameters is completed. The invention also discloses an EV-DO system of updating the terminal parametersthrough the air interface. The technical proposal of the invention updates the terminal parameters of the EV-DO through the air interface and can avoid that mass users carry units to a service network and manually modify the parameters, improve the operation and maintenance efficiency of the EV-DO system and is convenient for the users to use.

Description

technical field [0001] The invention belongs to a CDMA2000 1x wireless high-speed packet data (EV-DO) communication system, and particularly relates to an EV-DO system for updating terminal parameters through an air interface and a realization method thereof. Background technique [0002] At present, the CDMA20001xEV-DO system generally consists of a packet data service node PDSN (Packet Data Serving Node), an authentication, authorization, and accounting AAA server, a base station controller BSC, a base station transceiver BTS, an access network AN_AAA server, and a terminal AT (AccessTerminal ) composition, such as figure 1 As shown, the BSC and the BTS can be collectively referred to as the access network AN (AccessNetwork), and the AAA and the PDSN are core network side devices, and the AAA completes the authentication work of the user dialing. [0003] The above-mentioned AT stores the user's parameter information, ptl list, username, password and other logical units, ...

AI Technical Summary

Problems solved by technology

If some users do not come to modify, it may cause the terminal to be unavailable

Third, special equipment is required to update parameters, which involves a lot of confidential data in operation, and there are security problems

Fourth, the work cycle for updating parameters is long and the workload is heavy, which is not conducive to daily operation

Fifth, if it is necessary to initiate multiple parameter update activities, it is very unfavorable for the operator’s reputation and product reputation to call customers to the business outlets for parameter updates within a period of time.

Therefore, due to the dispersion of users and the uncertainty of parameter update operations, the above-mentioned methods appear to be inefficient, and are not practically operable in actual operations.
