Embodiment 1

[0129] Embodiment 1: access control in the side link.

[0130] When the relay UE determines that the side link no longer allows a new UE (or called a remote UE) to access the network through the relay UE, the relay UE may perform access control in one or more of the following ways:

[0131] Mode 1: The sidelink master information block (SL-MIB) message includes: the sidelink access control indication bit, when the indication bit is set to "true", it means that the relay UE does not accept new UEs passing through the relay The UE accesses the network.

[0132] For example, one or two reserved bits in the SL-MIB can be redefined as sidelink access control indicator bits.

[0133] Mode 2: When the relay UE receives a request from a new UE to access the network through the relay UE, it does not respond or rejects the UE's access request;

[0134] Optionally, the relay UE may send a reason for denying access to the new UE;

[0135] For example, the relay UE may send the cause to...

Embodiment 2

[0140] Embodiment 2: A new UE (or called a remote UE) accesses the network through a relay UE.

[0141] (1) When the new UE receives an indication from the side link message that it cannot access the network through the side link of the relay UE, the new UE cannot pass the relay within a predetermined time (for example, n seconds) The UE initiates a request to access the network.

[0142] It can be understood that the predetermined time period may be configured by the network side or stipulated by a protocol.

[0143] In particular, when the new UE needs to initiate emergency services or public safety (public safety) services, the indication received from the side link of the relay UE that the UE is not allowed to access the network through the relay can be ignored, that is, the new UE can pass through The relay UE initiates an emergency service or a public safety service.

[0144] (2) During the process of the new UE accessing the network through the side link of the relay ...

Embodiment 3

[0148] Embodiment 3: The relay UE determines the access control of the side link according to the system message of the serving cell.

[0149] The relay UE monitors the MIB, SIB and other messages of the serving cell, and determines whether to allow the new UE to access the network through the relay UE.

[0150] In the case of a combination of one or more of the following conditions, the relay UE shall be prohibited from providing access services to the new UE:

[0151] (1) When the relay UE monitors that the cellBarred in the MIB from the serving cell is set to "true";

[0152] (2) When the relay UE detects that cellReservedForOtherUse or cellReservedForFutureUse is set to "true" in the SIB1 message from the serving cell;

[0153] (3) When the relay UE monitors that the cellReservedForOperatorUse corresponding to a certain PLMN is set to "true" in the SIB1 message from the serving cell, and the PLMN is currently providing access services for the relay UE;

[0154] (4) Intro...

Abstract

The invention discloses an access control method and device. The method comprises the following steps: a relay terminal determines access control indication information of a side link and / or an access control behavior of the side link; and the relay terminal performs access control on a remote terminal according to the access control indication information and / or the access control behavior of the side link. In the embodiment of the invention, the relay terminal can perform access control on the far-end terminal according to the determined access control indication information and / or the access control behavior of the side link, so that when the relay terminal provides a relay transmission service between the far-end terminal and the network side equipment, network access control can be effectively performed, and aggravation of network congestion or increase of signaling overhead is avoided.

Description

technical field [0001] The present application belongs to the technical field of communications, and in particular relates to an access control method and device. Background technique [0002] After the introduction of relay terminals to provide terminal-to-network relay services, the access of remote terminals to the network through side links will directly affect the service load of the network. Therefore, the PC5 interface also requires a set of access control mechanisms. If there is no access control mechanism of the PC5 interface, when the network is congested, the relay terminal can continue to allow new terminals to access the network through the relay terminal, which will aggravate network congestion, or the new terminal will be blocked after a complicated signaling process. If the base station refuses to provide services, the new terminal will eventually have to re-select other cells or relay terminals to provide services, which not only causes a large signaling ove...
