Abstract:
Embodiments of the present application provide a location management method, a control plane node, and user equipment. A first control plane node determines first location area management information of UE, where the first location area management information includes N levels of location area identity lists, and a periodic time value PTV and a reachable time value RTV that correspond to each level of location area identity list in the N levels of location area identity lists; and performs paging management based on the first location area management information. In a process of performing the paging management, the first control plane node determines a paging area in areas to which the N levels of location area identity lists belong, and performs the paging management only in the paging area, instead of performing the paging management in all the areas corresponding to the N levels of location area identity lists.
Abstract:
The method for obtaining data resources provided by the present invention includes: receiving, by a first base station, an obtaining request sent by a mobile terminal, wherein the obtaining request includes description information of a data resource requested to obtain; if the first base station determines that the data resource corresponding to the description information is not stored in a local cache, sending the obtaining request to a second base station, wherein a local cache of the second base station stores the data resource; receiving, by the first base station, the data resource corresponding to the description information sent by the second base station, and sending, the data resource to the mobile terminal. Embodiments of the present invention can prevent the problem that a lot of network uplink bandwidth is occupied after P2P transmission mechanism is introduced into a mobile network.
Abstract:
A session establishment method and apparatus is provided, to resolve a problem that a terminal device cannot establish a plurality of PDU sessions for a same APP based on a URSP. The method includes: A terminal apparatus receives indication information from a first network apparatus, where the indication information is used to indicate that a first application needs to be associated with at least two sessions; and establishes at least one session for the first application based on at least the indication information, so that the first application is associated with at least two sessions.
Abstract:
This application discloses a method for implementing a user plane security policy, an apparatus, and a system. In an implementation, a terminal apparatus may associate or establish a PDU session based on user plane security indication information that is of an application and that is sent by a network device. In another implementation, a PCF adds an obtained user plane security attribute requirement of the application to a PCC rule and sends the PCC rule to an SMF, so that the SMF performs QoS flow binding based on the user plane security attribute requirement. According to the foregoing method, the user plane security attribute requirement of the application can be met.
Abstract:
Example communication methods and communications apparatuses are provided to verify a user equipment route selection policy (URSP) used by a terminal apparatus. One example communication method includes obtaining information about a first application of at least one packet data unit (PDU) session, where the information about the first application is determined based on a first URSP, and then sending the information about the first application to a second network element, where the information about the first application is used to verify whether information about a second application of the at least one PDU session matches the information about the first application, and the information about the second application is information about an application to which a data packet in the at least one PDU session belongs.
Abstract:
A routing rule obtaining method, device, and system are provided. The method is applied to an MEC system and performed by a data bus controller, including: obtaining service information of at least one service in the MEC system, where service information of each service includes a service type and a service identity; generating a routing rule according to the service information of the at least one service, where the routing rule is used to indicate at least one path through which a data packet can pass; and sending the routing rule to a data bus, so that the data bus forwards, according to the routing rule, a received data packet to a service corresponding to the data packet. The service information of each service is dynamically obtained, so as to update a path indicated in a routing rule.
Abstract:
This application provides a communication method, a network element, a terminal apparatus, and a system. The communication method includes: receiving, by a first network element, first indication information from a second network element, where the first indication information is used to indicate that a current condition supports establishment of a session of a first network for a terminal apparatus; obtaining, by the first network element, first quality of service QoS control information of a first session of the terminal apparatus after receiving the first indication information, where the first session is a session established by the terminal apparatus by using a second network; and sending, by the first network element, the first QoS control information to the second network element. The communication method in the embodiments of this application can improve communication efficiency.
Abstract:
Embodiments of this application provide a data transmission method, including: receiving, by user equipment, a first message, where the first message is used to instruct the user equipment to activate a reflective quality of service RQ mechanism; generating, by the user equipment, an implicit quality of service implicit QoS rule according to the RQ mechanism; receiving, by the user equipment, a second message, where the second message is used to instruct the user equipment to stop using the RQ mechanism; and stopping, by the user equipment, using the RQ mechanism, and deleting the implicit QoS rule. The user equipment receives the second message indicating that using of the RQ mechanism needs to be stopped, and deletes the implicit QoS rule, so as to implement switching between an explicit QoS rule and the implicit QoS rule, and flexibly configure a QoS rule for uplink data according to a policy of an operator.
Abstract:
Embodiments of the present disclosure describes a protocol frame transmission method, apparatus, and system, and a node device. The protocol frame transmission method includes: encapsulating a protocol frame into at least one TCP data packet, where a last TCP data packet in the at least one TCP data packet includes indication information, and the indication information is used to indicate that the last TCP data packet is the last TCP data packet corresponding to the protocol frame; and sending the at least one TCP data packet to a node device.
Abstract:
This application provides a data transmission method and apparatus, and relates to the field of communications technologies, to split data of different applications to different access network apparatuses. The method includes: A session management network element receives radio access technology RAT preference parameter information sent by a policy management network element, and sends the RAT preference parameter information to at least one of an access network apparatus, a terminal apparatus, and a user plane function UPF network element. The RAT preference parameter information is used to indicate a target radio access technology used to transmit data of a target application. The method is used in a process in which a terminal apparatus performs data transmission.
