Abstract: A communication method and apparatus are provided. The method includes: A network repository function network element receives a discovery request message including a type of a network element that requests to be discovered. The network repository function network element determines a second network element based on the type of the network element that requests to be discovered, and sends an identifier of a first dataset, a first token, and an identifier of the second network element to the first network element, where the first token authorizes the first network element to obtain the first dataset. According to the foregoing designs, the network repository function network element can provide, to the first network element, an identifier of a network element and information needed for obtaining the dataset, so that the first network element can determine, based on the dataset, whether to access the network element.

Abstract: This application discloses a communication control method and a communication apparatus, to provide a technical solution for performing communication control on a terminal device based on relative location information between terminal devices, so as to improve precision and flexibility of performing communication control such as access control or service control on the terminal device. In the method, a first network element obtains control indication information for a first terminal device from a second network element, where the control indication information includes a device identifier of a second terminal device that has a location binding relationship with the first terminal device. The first network element obtains relative location information between the first terminal device and the second terminal device. The first network element performs communication control on the first terminal device based on the control indication information and the relative location information.

Abstract: Embodiments provide a location area management method, a control node, and user equipment (UE). The method is applied to a communications system including a control plane node, and the control plane node stores an upper-level area identity list of UE. The control plane node determines a lower-level area identity list of the UE based on the upper-level area identity list. The control plane node sends the lower-level area identity list to the UE. When the upper-level area identity list is allocated to the UE, the lower-level area identity list is allocated to the UE. The lower-level area identity list includes fewer areas than the upper-level area identity list, so that when the control plane node pages the UE, paging is performed in an area corresponding to the lower-level area identity list, thereby reducing signaling overheads of a network side device.

Abstract: Embodiments of the present invention provide a method and a device for associating a user with a group. The method includes: receiving, by a first communications device, a first association request sent by a second communications device, where the first association request includes an identifier of an MCPTT user and identifiers of N MCPTT groups, and N is a positive integer; associating the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user; and sending a first association response to the second communications device, where the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≦M≦N, and M is an integer. In this way, the MCPTT user is associated with the M MCPTT groups that the MCPTT user is interested in.
