Problems solved by technology

[0005] The RNC obtains the location information of the UE after establishing the RRC connection, so as to judge whether the UE can be accepted according to the location information; during the process of obtaining the location information by the RNC, the UE will interact with the core network at the same time (such as registration, SMS transmission, etc.); If the UE does not report the location information in time or the signaling interaction delay between the UE and the core network is very short, the RNC may not have obtained the location information of the UE, and the registration process (or short message transmission process) of the UE has ended, causing the RNC to Unable to perform access control on UE in time

Embodiment 1

[0033] Embodiment 1 of the present invention provides an access control method, so that the wireless access device can obtain the timing advance information of the UE in time, and based on the timing advance (equivalent to the loopback delay between the UE and the wireless access device) , which can calculate the distance between the UE and the wireless access device) information to perform access control on the UE; the application scenarios of this method include but are not limited to: TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) system, LTE (Long Term Evolution, long-term evolution) system; such as figure 1 As shown, the method includes the following steps:

[0034] In step 101, the UE determines timing advance information, and sends a request message to a wireless access device, and the request message carries the timing advance information.

[0035] In the embodiment of the present invention, ...

Embodiment 2

[0056] based on figure 2 In the application scenario, Embodiment 2 of the present invention provides an access control method, which can be applied to TD-SCDMA system and LTE system; for example image 3 As shown, the method includes the following steps:

[0057] In step 301, the UE sends an RRC connection establishment request message to the wireless transceiver unit, and the RRC connection establishment request message carries timing advance information (TA information).

[0058] Step 302, after receiving the RRC connection establishment request message, the wireless transceiver unit forwards it to the resource management unit.

[0059] In a preferred implementation manner, the wireless transceiver unit may also acquire time calibration information of the timing advance of the UE, and forward the time calibration information and the RRC connection establishment request message to the resource management unit.

[0060] Step 303, after receiving the RRC connection establish...

Embodiment 3

[0065] based on figure 2 In the application scenario, Embodiment 3 of the present invention provides an access control method, which can be applied to a TD-SCDMA system; for example Figure 4 As shown, the method includes the following steps:

[0066] Step 401, after the UE establishes the RRC connection, if a cell update occurs during the UE's movement (for example, a cell update caused by a radio link failure, or a cell update caused by a cell change, etc.), the UE sends a cell update to the wireless transceiver unit A request message, the cell update request message carries timing advance information (TA information).

[0067] Step 402, after receiving the cell update request message, the wireless transceiver unit forwards it to the resource management unit.

[0068] In a preferred implementation manner, the wireless transceiver unit may also acquire time calibration information of the UE's timing advance, and forward the time calibration information and the cell update ...

Abstract

The invention discloses an access control method and access control equipment. The method comprises the following steps that: wireless access equipment receives a request message from user equipment (UE), wherein the request message carries time advance information; and the wireless access equipment performs access control on the UE according to the time advance information. According to the embodiment of the invention, the wireless access equipment acquires the time advance information of the UE in a radio resource control (RRC) connection establishment process or a cell updating process, so that the access control over the UE can be realized on the basis of the time advance information of the UE, and the access of the UE is further timely controlled.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access control method and equipment. Background technique [0002] When the UE (User Equipment, user equipment) initiates a service, it first establishes an RRC (Radio Resource Control, radio resource control) connection with the RNC (Radio Network Controller, radio network controller) on the radio access network side; after that, the UE and the core The signaling connection is established on the network side to perform processes such as registration, calling, and short message transmission. [0003] In the prior art, the distance between the UE and the base station is represented by the timing advance, and the UE will report the measurement result of the timing advance to the RNC according to the requirements of the RNC after the UE establishes an RRC connection; therefore, the current location-based The access control can only be performed after the RRC conne...
