This disclosure discloses communication methods and apparatuses. One example method includes: obtaining slice information of a session, sending a first message to a network function repository function network element, and receiving identification information of an intermediate session management function network element from the network function repository function network element. The intermediate session management function network element is configured to manage an intermediate user plane function network element, and the intermediate user plane function network element is configured to forward service data between an access network device to which a terminal is connected and an anchor user plane function network element in response to the terminal moving out of a service area of the anchor user plane function network element and a service area of an anchor session management function network element.

The disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments of the disclosure, a method performed by a Radio Access Network (RAN) Intelligent Controller (RIC) is provided. The method includes receiving a report message from an E2 node, generating a control message, based on the report message, and transmitting the control message to the E2 node. The control message may include an RAN configuration related to the E2 node. The report message may include at least one of User Equipment (UE) assistance information transmitted from a UE and UE expected behavior-related information transmitted from an Access and Mobility management Function (AMF).

Disclosed are a method and apparatus for recovering an RRC connection, and a computer storage medium. The method includes a target base station receiving an RRC connection recovery request message sent by a terminal. The method also includes the target base station determining, according to a UE identifier in the RRC connection recovery request message, a first node served by the terminal, and acquiring a UE context from the first node. The UE context includes a first UE context at a first node side and a second UE context at a second node side. The method further includes the target base station sending an RRC connection recovery message to the terminal, so that the terminal recovers an RRC connection.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method and device for switching a serving cell.

Presented herein are techniques to provide data session continuity for parallel data sessions involving a multiple Universal Subscriber Identity Module (MUSIM) user equipment (UE). In one example, a method may include obtaining an indication that session continuity for a first session associated with a first data network and a first USIM of a UE is allowed with respect to a second USIM in which the UE communicates first traffic for the first session via the first USIM. The method may further include determining that second traffic for a second session is to be communicated via the second USIM of the UE and, based on the indication that session continuity for the first session is allowed with respect to the second USIM, providing service information to the UE for the first session to enable the UE to communicate both the first traffic and the second traffic via the second USIM.

A system described herein may provide a technique for the seamless transfer of services provided by a first Multi-Access/Mobile Edge Computing device (“MEC”) to a User Equipment (“UE”), to a second MEC. Context information associated with a given application for which services are provided by the first MEC may be cached by the UE based on a determination that the second MEC should provide the services, and the UE may provide the cached information to the second MEC in order to seamlessly continue receiving services. The providing of the cached information to the UE and/or to the second MEC may be performed with an elevated priority level, in order to facilitate the seamless providing of the services relating to the application, thus resulting in minimal to no interruption of the user experience associated with the application.

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.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Methods, systems, and devices for wireless communication are described. A method may include determining to modify current-allowed network slices used by a user equipment (UE) based on a network-trigger; identifying new-allowed network slices for the UE based on the determining; selecting a target access and mobility management function (AMF) based on the new-allowed network slices, the target AMF is accessible by the source AMF; and triggering an AMF relocation based on the selecting.

A method according to a first example embodiment is performed by a user equipment, UE, in connection with a first network node in a first cell. The method comprises: receiving (202) a first request from the first network node in the first cell redirecting the UE to an indicated carrier or radio access technology, RAT. The first request comprises: an indication that the UE should enter an inactive state, and an indication that the first request relates to a Multimedia Priority Services, MPS, session. The method further comprises, responsive to receiving the first request: entering (204) an inactive state; selecting (206) a second cell on the indicated carrier or RAT; and resuming (208) a connection for the MPS session on the second cell. The connection is resumed with priority.
