Example communication methods and apparatus are described. In one example method, a first entity sends an access request of a terminal to a second entity. The second entity determines whether to allow access of the terminal, and sends an access response to the first entity. In response to the access response indicating that access of the terminal is allowed, the first entity sends a radio bearer (RB) setup request to the second entity. The second entity determines whether to allow setup of an RB to the terminal, and sends an RB setup response to the first entity. In response to the RB setup response indicating that setup of the RB to the terminal is allowed, the first entity triggers setup of the RB to the terminal.

Communication method, apparatus, and system

Example communication methods, apparatus, and systems are described. One example system includes a centralized unit control plane (CU-CP) and at least one distributed unit (DU). The CU-CP includes at least one first entity and a second entity, where the second entity is configured to perform a function of a radio resource management (RRM) algorithm in a base station, and the at least one first entity is configured to perform functions of a packet data convergence protocol (PDCP) layer and a radio resource control (RRC) layer in the base station.

A method, apparatus and communication system for registering address information of a network anchor point to a network server, the method including receiving, by a packet data network gateway, a request message from a mobility management entity, determining, by the packet data network gateway in response to the request message, to register identity information of the packet data network gateway to a home subscriber server, and registering, to the home subscriber server, by the packet data network gateway in response to the determining to register the identity information, the identity information of the packet data network gateway and an access point name corresponding to the packet data network gateway.

Method and communication system for storing address of network anchor point to network server

Methods, systems, and apparatus for information exchange are provided. In one aspect, an information exchange method includes establishing a link setup between a centralized unit-control plane (CU-CP) and a centralized unit-user plane (CU-UP) by at least one of sending a first link setup request to the CU-UP using an address of the CU-UP and receiving a first link setup response returned by the CU-UP; or receiving a second link setup request sent by the CU-UP based on an address of the CU-CP and returning a second link setup response to the CU-UP based on the second link setup request. The first and second link setup requests each carry at least one of an identifier of the CU-UP or a name of the CU-UP. The first and second link setup responses each carry at least one of an identifier of the CU-CP or a name of the CU-CP.

Network architecture and information exchange method and apparatus

Embodiments of this application disclose a communication method and a communications apparatus. A source base station instructs a terminal to hand over from the source base station to a target base station, and sends, to the terminal, configuration information of a second connection required for communication between the terminal and the target base station. The terminal maintains a first connection for communication with the source base station, and establishes the second connection for communication with the target base station based on the configuration information of the second connection. The solutions in the embodiments of this application reduces latency in a handover process.

Communication method and communications apparatus

A method, apparatus and communication system for registering address information of a network anchor point to a network server are disclosed. A network apparatus, such as a mobility management entity, determines whether to register address information of a network anchor point to a network server, and registers the address information of the network anchor point to the network server when determining to do so.

A method, device and system for implementing optimized inter-RAT handover are disclosed. In the method, a user equipment or a source network decides to prepare for a handover to a target network. A corresponding target network ID is obtained from a configured mapping between cell IDs and target IDs according to a received cell ID. Target network bearers are set up after determining an access node of the target network. The user equipment is connected to the target network after handover preparation is complete.

Method, device and system for implementing optimized inter-rat handover

The present invention relates to the communication field and discloses a method, an apparatus, and a system for processing priority services to overcome a problem in the prior art that priority services initiated from a network to a target user cannot be provided. The technical solutions provided in the embodiments of the present invention include: determining a service to be carried out with a target user equipment as a priority service; and creating a priority service bearer for the priority service, and carrying out the priority service by using the priority service bearer. The embodiments of the present invention are applicable in an IMS-based communication system.

Method, apparatus and system for processing priority services

A method, network server, and communication system for deleting an address of a network anchor point from a network server is disclosed. A MMM sends an instruction to the network server to instruct the network server to delete an address of a network anchor point that has been previously stored in the network from. The network server deletes the address of the network anchor point from the network server.

Method and communication system for deleting address of network anchor point from network server

A method, device and system for implementing optimized inter-RAT handover are disclosed. When a user equipment or a source network prepares for a handover to a target network, a corresponding target network ID is obtained from a configured mapping between cell IDs and target IDs according to a received cell ID, target network bearers are established following identification of an access node of the target network, and the user equipment is connected to the target network after handover preparation is complete. With the present invention, when a user equipment is handed-over from a source network to a target network, service continuity can be maintained with an enhanced quality of user experience.

Method, device and system for implementing optimized inter-RAT handover

A method obtains area information during handover between heterogeneous networks. A mobility management entity of a destination network receives location area related information of a User Equipment (UE) from a mobility management entity of a source network. The mobility management entity obtains location area information required by the UE according to the location area related information. The mobility management entity sends the location area information required by the UE to the UE.

Method, apparatus and system for obtaining location area information during handover between heterogeneous networks

A method for storing an address of a network anchor point to a network server is provided The provided method includes the following steps: a terminal initiates an attach request or a bearer establishment request, and a network selects a network anchor point; and when the network anchor point assigns a first bearer context to the terminal, or a first connection is established between the network anchor point and the terminal, the network registers an address of the network anchor point to a network server. A method for deleting an address of a network anchor point from a network server is also provided, which includes the following steps: when a terminal or an entity in a network initiates a delete bearer request, the network instructs a network server to delete an address of a network anchor point that has been registered to the network server if the network anchor point no longer serves the terminal; and the network server deregisters the address of the network anchor point. A communication system is further provided.
