[0022] In fact, the current network is a shared network, but user equipment may only be authorized to perform ProSe services in a specific public land mobile network (PLMN: Public Land Mobile Network) in the shared network, so the above rules do not apply to shared network, because the above rules can cause unlicensed users in a specific PLMN to perform ProSe services authorized in other PLMNs in shared cells
[0023] In addition, user equipment should access the network to request resource allocation for mode 1 direct communication and type 2 direct discovery. Before performing ProSe services, user equipment should access the network to obtain authorization information. If many user equipment expect to perform ProSe at the same time business, it will significantly increase the load of the network. So far, the existing network does not restrict the access of user equipment performing ProSe services to the network
If the existing access control mechanism is adopted, it will affect the normal business of ordinary user equipment

Embodiment Construction
[0061] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It should be noted that although the steps of the relevant methods in the present invention are described in a specific order in the accompanying drawings, this does not require or imply that these operations must be performed in this specific order, or that all shown operations must be performed to achieve the desired result. As a result, instead, the steps described herein can be performed in a different order. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution.

The invention provides a method and device for controlling ProSe services in a communication system. The base station sends the first PLMN identifier and carrier frequency information of at least one carrier frequency of other PLMNs used to indicate that the user equipment of other PLMNs can perform the ProSe service to the user equipment in the shared cell, and when the user equipment is in an idle state, perform cell reconfiguration selection or PLMN selection, when in the connected state, execute the handover process. If the handover fails, the RRC connection is released to enter the idle state or the DRX configuration is performed and the ProSe service is executed during the DRX sleep time. Based on the solution of the present invention, the user equipment can perform ProSe services on the carrier frequency indicated by the carrier frequency information through cell reselection or switching, thereby avoiding the overload problem caused by performing too many ProSe services in the shared cell at the same time.
Description
technical field [0001] The present invention relates to a communication system, and in particular to a method and a device for controlling Proximity-based Services (Proximity-based Services) services in the communication system. Background technique [0002] The introduction of Proximity-based Services (ProSe: Proximity-based Services) in the LTE system has been approved. At present, RAN1 / 2 has made great progress in device-to-device (Device to Device, D2D for short) discovery and communication. [0003] According to the consensus reached such as R2-141859, when a user equipment (UE: UserEquipment) with ProSe capability needs to perform direct communication (Direct Communication), it can operate in the following two modes for resource allocation: [0004] Mode 1 - base station scheduling resource allocation: [0005] - UE needs to be in connected state (RRC_CONNECTED) for data transmission. [0006] - The user equipment requests transmission resources from the base statio...
