Abstract
The invention provides a method and a device for localizing a public network access function of management and control equipment. The method comprises the following steps that: a pseudo base station camouflages as a public network base station, and starts radio-frequency work; the pseudo base station makes mobile terminals under radio-frequency coverage reside on basic working frequency points; the pseudo base station selects a non-public-network frequency point to serve as a management and control working frequency point, and redirects the mobile terminals residing on the basic frequency points to the management and control working frequency point; and the pseudo base station stops working of the basic working frequency points, and makes a pseudo terminal access to a public network. A frequency isolation way is adopted instead of a spatial isolation way, so that the pseudo terminal can directly access to the public network locally on the pseudo base station, thereby solving the problem of difficulty in spatial isolation arrangement, and greatly improving the portability and flexibility of the equipment.

Step 403: pseudo-base station sends registration to the mobile terminal registered in management and control working frequency points and accepts, and terminal is resided in management and control working frequency points.
Step 500: pseudo-base station stops basic frequency work, control pseudo-terminal access public network, after receiving confirmation, the equipment authorization terminal that namely can be in management and control region provides public network service to access.That is, pseudo-base station, after detecting whether the mobile terminal on all basic frequencies is redirected to management and control working frequency points, stops basic frequency work, controls pseudo-terminal and is switched to public network.In this step, management and control frequency due to pseudo-base station is non-public network frequency, the frequency of carrying out registering to public network base station of pseudo-terminal is as public network frequency, therefore, achieve the frequency isolation of pseudo-base station and pseudo-terminal, pseudo-terminal directly at pseudo-base station access public network, can be solved space isolation and lays the difficult problem brought, substantially increase portability and the flexibility of equipment.
Wherein, stop basic frequency work, pseudo-base station controls pseudo-terminal and is switched to public network, comprises the following steps:
Step 501, pseudo-base station is checking whether the mobile terminal on all basic frequencies is redirected to management and control working frequency points, when check result is for being, then stops basic frequency work.
This step specifically comprises:
Step 5011, a pseudo-base station initiated timer, preset duration scope is 2 to 5 seconds;
Step 5012, timer then before, judge that whether the mobile terminal of all management and control has all initiated registration and resident in management and control working frequency points;
Step 5013, if so, stops basic frequency work immediately and deletes timer;
Step 5013, if not, judges whether then timer, when then, forces to stop basic frequency work.
Step 502, pseudo-base station controls pseudo-terminal access public network, and after receiving confirmation, the management and control devices authorization terminal that namely can be in management and control region provides public network service to access.Authorization terminal refers to the terminal that can access public network in the mobile terminal of pseudo-base station management and control.
This step specifically comprises:
Step 5021, pseudo-base station instruction pseudo-terminal starts to search for public network signal;
Step 5022, pseudo-terminal receives the automatic resident public network work of system message of public network, gives pseudo-base station in response to confirm that public network accesses successfully simultaneously;
Step 5023, pseudo-base station, after receiving confirmation, can provide public network access service to authorized service request.
