Problems solved by technology

This version of FWP can only use the dedicated SIM card provided by the operator under the network, which will lead to conflicts between the actual FWP version used and the version during testing and production verification, such as developing for a foreign operator The FWP cannot be tested and production verified under China Mobile's network
[0004] Currently, there is no easy way to effectively resolve this contradiction

Embodiment Construction

[0013] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0014] In the embodiment of the present invention, control is performed using a specified function flag item, and here, the function flag item may be an NV item, which is used to mark whether to enable the network lock or card lock. When the NV item is marked as FALSE, it means that the ordinary SIM card is used under normal network conditions and has all normal functions; when the NV item is marked as TRUE, it means that the special network required by the operator can only be used by the operator. The specific steps are shown in Figure 1 with reference to the dedicated SIM card.

[0015] As shown in Figure 1, the method for realizing the controllable network lock / card lock based on the wireless fixed phone according to the embodiment of the present invention includes the following steps:

[0016] Step S102, add a function mark for indicating whether to open t...

Abstract

The invention discloses a controllable network / card-lock implementing method based on wireless hand-free telephone, comprising the steps of: 1. adding network / card lock with a functional label indicating whether to open the network / card lock function; 2. when the network / card lock is downloaded to the hand-free telephone, defaulting the network / card lock function as close; and 3. after test and production verification in the existing network, modifying the functional label and inquiring to determine the current state, where the functional label is a variant in a nonvolatile memory and includes network lock label and card lock label and can be a network / card lock label. And the invention can simply implement compatibility between the actually used FWP version and the version of test and production verification.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for implementing controllable network lock / card lock based on wireless fixed phones. Background technique [0002] Fixed wireless phone (FWP), also known as wireless local phone, is a wireless access terminal, similar in appearance to ordinary telephones, but adopts wireless access methods such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM), and can It can be used anywhere within the coverage of the wireless network, answering and making local, domestic and international calls anytime and anywhere. [0003] FWP is usually developed for the customized needs of operators. Now, in order to develop rural users or wireless public telephones, operators provide a series of price discounts such as one-way charging. Therefore, in order to prevent this phone from being used in other networks, or the dedicated SIM card...
