A method for data forwarding in a small cell system comprises: sending by a master base station (MeNB) to a target secondary base station (SeNB) information of a source SeNB or a source SeNB cell where a user equipment (UE) is located; determining by the target SeNB whether a direct data forwarding is feasible; notifying, by the target SeNB, the MeNB whether the direct data forwarding is feasible; and determining by the MeNB whether it is a direct data forwarding or an indirect data forwarding. The method for data forwarding provided in the present application may support both the direct data forwarding and the indirect data forwarding based on actual situation of the network, reduce data loss and failure of data forwarding, and improve the efficiency of data forwarding.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.

There is provided method for managing network resources by switching the slice used to support a user equipment (UE), in a process referred to as slice handover or slice switching. There are several reasons why a slice handover may be implemented, include movement of the UE and network load balancing. Further the UE can be switched to a new slice operated by the same service provider (intra-operator handover) or a different service provider (inter-operator handover).

A method includes receiving cell reselection information from a radio access network device. The cell reselection information includes an identifier of at least one carrier frequency, an identifier of a network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice that is information of a specific service type of the network slice or a network slice set identifier corresponding to the network slice. The method further includes in response to the terminal device performing cell reselection, selecting a cell on a carrier frequency of the network slice supported by the terminal device as a reselected to-be-camped cell based on the identifier of the at least one carrier frequency, the identifier of the network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice.

There are provided measures for improved service continuity with mobile edge computing. Such measures exemplarily comprise detecting a handover of a communication endpoint from a first gateway to a second gateway, determining, whether an ongoing mobile edge computing related application session of said communication endpoint is routed by said first gateway, checking, upon positive result of said determining, whether said ongoing mobile edge computing related application session fulfills a predetermined condition, and initiating, upon positive result of said checking, a swap of said ongoing mobile edge computing related application session from said first gateway and a first mobile edge computing entity connected to said first gateway to said second gateway and a second mobile edge computing entity connected to said second gateway.

An apparatus and method can include monitoring whether a consumer of a target network receives a resource identifier, a first apiRoot identifying a producer, and a second apiRoot identifying the producer and a producer network. The first apiRoot is for routing a service request to the producer, and the second apiRoot is for routing the service request to the producer if the target network is different from the producer network. The method further comprises identifying the producer network based on the second apiRoot, and deciding whether the target network is different from the producer network. If the target network is not different from the producer network, the service request is sent wherein the resource is identified by the first apiRoot and the identifier. If the target network is different from the producer network, the service request is sent wherein the resource is identified by the second apiRoot and the identifier.

Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.

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.

Embodiments relate to systems and methods for modifying the playback rate of media data in order to improve craft-based media playback system performance during handover events in a communication system.

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.
