Embodiment Construction

[0039] Hereinafter, the method of the present invention will be described in detail.

[0040] The network locking method of the CDMA2000 terminal equipment of the present invention adopts the method of software control in the CDMA2000 terminal equipment, and can judge the network and working parameters waiting to be written into the terminal equipment: first, determine whether writing these parameters may cause the terminal equipment to break away The prescribed registry network then decides whether to allow writes. In order to prevent illegal parameters from being written into the terminal device and cause it to leave the registered network, the present invention also adopts a method for security detection of its own parameters and the obtained network when the terminal device starts and obtains the network: If it is found that the parameters are not specified by the registered network, the initialization process is terminated, and if the obtained network is a prohibited netw...

Abstract

The method includes following steps: judging network in waiting for writing to terminal device and operational parameter to determine whether these parameters to be written can cause the terminal device to break away from the stated registered network; if yes, refusing writing in; otherwise write is enable. Since terminal device can select working network, the disclosed locking method only locks stated network. No matter how strong the signal on network is, the method does not lock terminal device in the network, in which locking operation is prohibited. Moreover, even if when illegal parameter is written to a terminal accidentally, the method guarantees the terminal is unable to work normal in the network not registered in. the invention realizes selectable network locking and providing safe and reliable locking.

Description

technical field [0001] The invention relates to a network locking method for communication terminal equipment, in particular to a network locking method for CDMA2000 terminal equipment. Background technique [0002] The air interface standards used in the prior art, such as IS-2000 and IS-95B, do not specify the specific method for the terminal device to search the network. The network search method of the terminal equipment is designed by the equipment manufacturer itself. The advantage of doing this is that the CDMA terminal equipment manufacturer has greater flexibility and can use their own optimal methods to search and obtain the network. But this also makes the air interface standard unable to clearly stipulate the network locking method. [0003] Normally, a CDMA terminal device always selects the network with the best RSSI (Received Signal Strength Indicator) to obtain the best communication quality. For situations where there is only one operator in a given locati...
