Abstract: In a method for performing access control on user equipment, a mobility management device receives from an access node device an access type parameter of the user equipment. The access type parameter indicates a radio access type of the user equipment or a type of the access node device. The mobility management device determines, based on the access type parameter, a connection type of the user equipment in accessing a core network, wherein the connection type is either single connectivity or dual connectivity. The mobility management device then performs access control on the user equipment based on the connection type of the user equipment.

Abstract: A communication method and apparatus, where the method includes: A first mobility management network element in a first network obtains information about N intermediate session management network elements that are capable of serving a terminal in the first network, and determines that a combined intermediate session management network element (which is capable of providing session management in the first network and in a second network) in the N intermediate session management network elements is a first intermediate session management network element corresponding to a first session of the terminal in the first network, such that overall communication efficiency of the network is improved. For example, network address resources are reduced to simplify network planning and deployment complexity, a quantity of nodes in the network is reduced to simplify network operation and maintenance workload, and signaling between the nodes in the network is reduced to reduce network service load.

Abstract: A service continuity implementation method, a related device, and a system, where when a user equipment is attached to a 2/3G network, a serving node device determines that the user equipment has a 5G capability or a user corresponding to the user equipment is a 5G user. Then, the serving node device selects a 5G gateway for the user equipment, and establishes a session with the 5G gateway. In this way, when the user equipment subsequently moves to a 5G network, the same 5G gateway serves the user equipment, and an address of the user may remain unchanged when the user equipment moves from the 2/3G network to the 5G network, thereby implementing service continuity of the user.

Abstract: A communication method is applied to a scenario in which a terminal moves from a first preset area of a first network to a second preset area of a second network. The method includes that a first core network device in the first network determines that Evolved Packet System (EPS) fallback of the terminal is triggered, and sends first information to a second core network device in the second network. The first information includes a first identifier or first indication information. The first identifier identifies a first dedicated bearer corresponding to the terminal. The first dedicated bearer includes a voice dedicated bearer or a video dedicated bearer. The first indication information indicates that the terminal falls back to the second network using an EPS fallback procedure.

Abstract: A service continuity implementation method, a related device, and a system, where a mobility management device may select a 5G gateway for a 5G user equipment handed over to a 4G network, and establish a session with the 5G gateway. The 5G gateway may send a 5G-related parameter to the user equipment in advance. Therefore, after the user equipment moves from the 4G network to a 5G network, service continuity is maintained, that is, a service in the 4G network continues to be maintained in the 5G network.

Abstract: This application provides a communication method, apparatus, and system for a voice service. The method includes: A session management network element determines that a terminal device is to be handed over from a first network to a second network. The session management network element waits until a first moment to send a request message to a mobility management network element in the second network, where the request message is used to request to set up a first bearer for a voice service of the terminal device.

Abstract: A first location management network element receives first positioning request information from an access management network element, where the first positioning request information includes an identifier of a gateway mobile location center network element that requests location information, and the location information is a location of a terminal device. The first location management network element determines, based on the identifier of the gateway mobile location center network element that requests the location information, whether to allow a positioning request from the gateway mobile location center network element that requests the location information. The first location management network element sends first positioning request response information to the access management network element, where the first positioning request response information is used to notify the access management network element whether the positioning request for the terminal device is allowed.
