Problems solved by technology

[0007] In prior art 1, all users in the cell are paged only because the EAB information has changed, and the paging message only informs that the broadcast message has changed. Users do not know whether the change involves EAB information, and users who have not configured EAB also It is obviously a big waste for users who do not configure EAB to read paging messages that are useless to themselves
[0008] In prior art 2, paging messages are used to carry EAB information, which saves the operation of users to receive broadcast messages, but users who do not configure EAB will still receive useless paging messages; and the capacity of paging messages is limited, Limit the capacity of EAB information

Embodiment 1

[0042] see figure 1 , an embodiment of the present invention provides a method for obtaining access control information, the method comprising:

[0043] Step 101: Receive the control message scrambled by the first identifier sent by the network side. The control message scrambled by the first identifier can be monitored by users configured with extended access control (EAB), and users not configured with EAB cannot listen to it. The control message contains scheduling information on the physical downlink control channel PDCCH;

[0044] Step 102: Descramble the control message scrambled by the first identifier to obtain the control message, and receive the radio resource control RRC message on the physical downlink shared channel PDSCH according to the scheduling information in the control message, and the RRC message contains EAB related information ;

[0045] Step 103: Obtain EAB information according to EAB related information.

[0046] In the method provided by the embod...

Embodiment 2

[0049] In the embodiment of the present invention, the EAB-related information is specifically EAB information, and the EAB information is set in the RRC message on the network side. The user knows that the EAB information has changed through the X-RNTI identifier. In practical applications, the EAB information is used for users who configure EAB. The RRC message can be a new message or an existing message, such as scheduling PAGING messages, etc. .

[0050] see figure 2 , an embodiment of the present invention provides a method for obtaining EAB information, the method comprising:

[0051] Step 201: Receive an X-RNTI scrambled control message from the network side, where the control message includes scheduling information on the PDSCH channel.

[0052] The implementation of the embodiment of the present invention is mainly for users who configure EAB, and only for the scenario where the EAB information of the cell changes. Specifically, the network side sends a control mes...

Embodiment 3

[0060] In the embodiment of the present invention, the EAB-related information is specifically the EAB indication information. The EAB information is set in the broadcast message on the network side, and an RRC message is used to indicate the EAB information. The RRC message contains the EAB indication information, and the indication information appears After that, it can be judged that the EAB information in the broadcast message has a new update, so as to obtain the EAB information from the broadcast message. In practical applications, the EAB information is used for the user who configures the EAB, and the RRC message may be a new message or an existing message, such as a scheduling PAGING message.

[0061] see image 3 , the embodiment of the present invention proposes a method for obtaining EAB information, the method comprising:

[0062] Step 301: Receive a control message delivered by the network side, the control message includes scheduling information on the PDSCH ch...

Abstract

The invention discloses a method, a device and a system for obtaining access control information, and belongs to the field of communication networks. The method includes the following steps: receiving control information which is sent by a network side and is scrambled by first identification, wherein the control information can be monitored by users with an extended access control embedded array block (EAB) configured, the control information can not be monitored by users with the extended access control EAB not configured, and the control information contains scheduling information on a physical downlink control channel (PDCCH); descrambling the control information to obtain the control information, and receiving radio resource control (RRC) information on a physical downlink shared channel (PDSCH) according to the scheduling information in the control information, wherein EAB relevant information is contained in the RRC information; and obtaining EAB information according to the EAB relevant information. By means of the method, the device and the system for obtaining the access control information, X-radio network temporary identity (RNTI) identification arranged specially for the user with the EAB configured, when only does the EAB information vary, ordinary H2H users can not receive the RRC information, and thus received quantity of ordinary users is reduced.

Description

technical field [0001] The present invention relates to the field of communication networks, in particular to a method, device and system for acquiring access control information. Background technique [0002] In the current communication network, before each terminal accesses the network, it judges whether it is allowed to access according to the access control information in the broadcast message. The access control information in the current broadcast message is for all users. When a user comes to this cell, he will actively read the broadcast message of the cell and store the broadcast message in the terminal. When the broadcast message of the cell changes, the base station will page all the users in the cell, and inform the users of the change of the broadcast message through a broadcast message change indication in the paging message. By using P-RNTI (Paging-radio network temporary identity, paging wireless network temporary identity) as the monitoring identifier of t...
