Problems solved by technology

However, in the current access control mechanism, the coverage enhancement level is not considered, and the congestion control cannot be reasonably performed, which may lead to a heavy network load

Embodiment 1

[0106] Embodiment 1: The cell broadcasts the access control parameters corresponding to each CE level under each access object.

[0107] Assuming that the cell supports coverage enhancement, the CE levels under the coverage of the cell are: CE level 1, CE level 2, and CE level 3. UE does not belong to any special AC (Access class). The specific access control methods include:

[0108] Step 1: The cell broadcasts the access control parameters corresponding to each CE level under each access object, for example:

[0109] For the MMTEL voice under the access object SSAC, broadcast its corresponding access control parameters:

[0110] When the CE level is 1, the access control parameters are configured as {the access control prohibition factor is 0.85, the access control prohibition time is 32s, and all ACs of special UEs are allowed to access};

[0111] When the CE level is 2, the access control parameters are configured as {the access control prohibition factor is 0.75, the a...

Embodiment 2

[0116] Embodiment 2: The cell broadcasts whether CE level is considered for each access object, and the corresponding access control parameters under each CE level.

[0117] Assuming that all PLMNs under a certain cell have the same access control parameters and support coverage enhancement, the CE levels under the coverage of this cell are CE level 1, CE level 2, and CE level 3. The UE does not belong to any special AC (Access class), and the UE side initiates mobile origin data (Mobile Original data, MO data), that is, the access object is MO data. The specific access control methods include:

[0118] Step 1: In addition to broadcasting the access control parameters of each access object, the cell also broadcasts whether CE level is considered, for example:

[0119] The access control parameter of MO data is {the access control prohibition factor is 0.8, the access control prohibition time is 64s, and access is allowed for the AC of special UE}, and the access control of MO...

Abstract

The invention discloses an access control method and device, which are used for better congestion control, avoiding the network load and improving the network performance. The access control method comprises the following steps of determining an access control parameter message of a cell, wherein the access control parameter message comprises a corresponding relation between a coverage enhancementlevel and an access control parameter in the cell; and sending the access control parameter message to user equipment (UE) in the cell.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an access control method and device. Background technique [0002] The terminal in the Internet of Things may be installed in the basement or other places where the path loss greatly exceeds that of ordinary LTE equipment. In order for the terminal to be served normally, it is necessary for the network side or the terminal to repeatedly transmit the downlink (DL) or uplink Link (UL) data, so that the peer can decode the correct data through merging. The coverage enhancement level (CE level) of the UE is different, and the required number of repeated transmissions is different. The higher the CE level, the weaker the current coverage of the UE is, and the more repeated transmission times are required, so that the UE side or the evolved base station (eNB) can analyze the correct data through combined decoding. For different CE levels, there are also correspon...
