DETAILED DESCRIPTION OF EMBODIMENTS
In carrying out the present application, the inventor has found: a RNC would necessarily query location information of a UE after the UE established a RRC connection, wait for the UE (and a base station) to report a measurement result, and calculate the location information of the UE according to the measurement result, thereby judging whether to accept the UE according to the location information. Further, after the RRC connection is established, during the process of the RNC querying location of the UE, it is required that the UE simultaneously interact with the core network (such as, performing registration process and short message transmission process) and thus, if the UE would not report timely, or in the case that a safe mode control is not enabled on the network side, the signaling interaction delay between the UE and the core network is short, the RNC might not query the location information of the UE while the registration process (or the short message transmission process) of the UE has ended, resulting in that the RNC cannot control the access of the UE timely at this time.
For the above findings, the embodiments of the present application are to provide an access control method and device, such that a wireless access device may acquire timing advance information of the UE (or location information of the UE) during an RRC connection establishment process or a cell updating process rather than acquiring the timing advance information of the UE (or the location information of the UE) after an RRC connection establishment process or a cell updating process, thus performing access control to the UP based on the timing advance information of the UE (or the location information of the UE), and then timely controlling the access of the UE.

Obviously, the described embodiments are only part but not all of the embodiments of the application. Based on the embodiments of the present application, all other embodiments obtained by an ordinary person skilled in the art without paying creative efforts will fall into the protection scope of the present application.
First Embodiment
The first embodiment of the present application is to provide an access control method, such that a wireless access device can timely acquire timing advance information of a UE and control the access of the UE based on the timing advance (equivalent to round trip delay between the UE and the wireless access devices, which can be used to calculate the distance between the UE and the wireless access device) information; application scenarios of the method may include but not be limited to: Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system and Long Term Evolution (LTE) system. As shown in FIG. 1, the method may comprise the following steps:
Step 101, a UE determines timing advance information, and sends a request message to a wireless access device, the request message carrying the timing advance information.
In the embodiment of the present application, the request message may include but not be limited to: an RRC connection establishment request message; a cell updating request message; and a User Registration Area (URA) updating message.
Step 102, the wireless access device receives the request message from the UE.
Step 103, the wireless access device controls the access of the UE according to the timing advance information.
In the embodiment of the present application, the process of the wireless access device controlling the access of the UE according to the timing advance information can adopt the following modes:
In first mode, the wireless access device controls the access of the UE according to the timing advance information.
Specifically, the wireless access device judges whether the timing, advance information satisfies a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE. When judging whether the timing advance information satisfies the condition of restricted access, it may judge whether the timing advance is greater than a preset time threshold (which can be selected based on practical experience), or, may judge whether the timing advance is less than a preset time threshold (which can be selected based on practical experience).
In the embodiment of the present application, a preferred implementation mode is as follows: the wireless access device may acquire time calibration information corresponding to the timing, advance information, and use the time calibration information to control the access of the UE. Specifically, the wireless access device judges whether the time calibration information satisfies a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE.
In second mode, the wireless access device determines location information of the UE according to the timing advance information, and controls the access of the UE according to the location information.
Specifically, the wireless access device determines location information of the UE according to the timing advance information, and judges whether the location information satisfies a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE. When judging whether the location information satisfies the condition of restricted access, it may judge whether the location information is greater than a preset distance threshold (which can be selected based on practical experience), or, may judge whether the location information is less than a preset distance threshold (which can be selected based on practical experience).
In the embodiment of the present application, a preferred implementation mode is as follows: the wireless access device may acquire time calibration information corresponding to the timing advance information, and use the time calibration information to control the access of the UE. Specifically, the wireless access device determines the location information of the UE according to the time calibration information, and judges whether the location information satisfies a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE.
In third mode, the wireless access device determines Angle of Arrival (AOA, which refers to direction information of the UE) information corresponding to the UE, and controls the access of the TIE according to the timing advance information and the AOA information.
Specifically, the wireless access device judges whether the timing advance information and the AOA information all satisfy a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE. When judging whether the timing advance information satisfies the condition of restricted access, it may judge whether the timing advance is greater than a preset time threshold (which can be selected based on practical experience), or, may judge whether the timing advance is less than a preset time threshold (which can be selected based on practical experience) when judging whether the AOA information satisfies the condition of restricted access, it may judge whether the AOA is within a preset range.
In the embodiment of the present application, a preferred implementation mode is as follows: the wireless access device may acquire time calibration information corresponding to the timing, advance information, and use the time calibration information to control the access of the UE. Specifically, the wireless access device judges whether the time calibration information and the AOA information all satisfy a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE.
In fourth mode, the wireless access device determines location information of the UE according to the timing advance information, and determines AOA information corresponding to the UE; and the wireless access device controls the access of the UE according to the location information and the AOA information.
Specifically, the wireless access device determines location information of the UE according to the timing advance information, and judges whether the location information and the AOA information all satisfy a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE. When judging whether the location information satisfies the condition of restricted access, it may judge whether the location information is greater than a preset distance threshold (which can be selected based on practical experience), or, may judge whether the location information is less than a preset distance threshold (which can be selected based on practical experience); when judging whether the AOA information satisfies the condition of restricted access, it may judge whether the AOA is within a preset range.
In the embodiment of the present application, a preferred implementation mode is as follows: the wireless access device may acquire time calibration information corresponding to the timing advance information, and use the time calibration information to control the access of the UE. Specifically, the wireless access device determines location information of the UE according to the time calibration information, and judges whether the location information and the AOA information all satisfy a condition of restricted access, and if so, rejects the access of the UE; otherwise, allows the access of the UE.
In conclusion, in the embodiment of the present application, the wireless access device may acquire the timing advance information of the UE (or the location information of the UE) during the RRC connection establishment process or the cell updating process, thus performing access control to the UE based on the timing advance information of the UE (or the location information of the UE), and then timely controlling the access of the UE.
Further, in a mobile communication network, because of some special reasons (for example, national boundaries, military areas, etc.), it is necessary that UE access is forbidden in a related area. By determining the distance (which is embodied as a timing advance measured by the UE) between the UE and the wireless access device and the location of the wireless access device, the location information of the UE can be acquired, and thereby the UE access can be controlled.

Step 303, after receiving the RRC connection establishment request message, the resource management module uses the timing advance information to control the access of the UE.
In a preferred implementation mode, the resource management module may also use the time calibration information (which can be received from the radio transceiver module, or obtained by the resource module itself) of the timing advance to control the access of the UE.
Specifically, the resource management module judges whether the timing advance of the UE satisfies a condition of restricted access (fox example, the timing advance is greater than a threshold, or the timing advance is less than a threshold); if the condition of restricted access is satisfied, the access of the UE will be rejected and an RRC rejection message may be sent to the UE through the radio transceiver module; if the condition of restricted access is not satisfied, radio resources will be allocated for the UE and an RRC establishment message may be sent to the UE through the radio transceiver module.
Further, the resource management module may also use the timing advance information to acquire location information of the UE (such as the distance between the UE and the radio transceiver module), and judge whether the location information of the UE satisfies a condition of restricted access; if the condition of restricted access is satisfied, the access of the UE will be rejected and an RRC rejection message may be sent to the UE through the radio transceiver module; if the condition of restricted access is not satisfied, radio resources will be allocated for the UE and an RRC establishment message may be sent to the UE through the radio transceiver module.

Step 401, after establishing an RRC connection of a UE, if a cell updating (for example, a cell updating caused by wireless link failure, or a cell updating caused by changing cell, etc.) occurs during movement of the UE, the UE sends a cell updating request message to a radio transceiver module, the cell updating request message carrying timing advance information (TA information).
Step 402, after receiving the cell updating request message, the radio transceiver module forwards it to a resource management module.
In a preferred implementation mode, the radio transceiver module may also obtain time calibration information of the timing advance of the UE, and forward the time calibration information and the cell updating request message to the resource management module.
Step 403, after receiving the cell updating request message, the resource management module uses the timing advance information to control the access of the UE.
In a preferred implementation mode, the resource management module may also use the time calibration information (which can be received from the radio transceiver module, or obtained by the resource module itself) of the timing advance to control the access of the UE.
