This disclosure generally relates configuration of transmission profile of data flows in communication networks and particularly relates to configuration of Quality of Service (QoS) profile for QoS flows. In some implementations, a first network element in the communication network may be configured to determine a plurality of transmission profiles for a data flow and transmit these profiles to a second network element. The second network element may adaptively select an active transmission profile from the plurality of transmission profiles for configuring the transmission of the data flow. The second network element may further modify the active transmission profile from the plurality of transmission profiles during an active transmission of the data flow without involving additional decision by the first network element.

The invention proposes solutions for monitoring and controlling the maximum number of the UEs registered in a Network Slice, the maximum number of the established PDU Sessions in a Network Slice and the maximum number of the Uplink and Downlink data rates per UE in a Network Slice. The invention also enforces access and service restriction in a Network Slice when the Network Slice parameters boundaries have been reached.

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). The disclosure provides a method and apparatus for configuring a relay node. A first node transmits to a second node a message that carries information on a radio bearer for a user accessing the second node. Configuration of the radio bearer for data transmission in a multi-hop network is realized through the above method and apparatus.

A method (80) of performing transfer of data packets requiring a specified Quality of Service, QoS, by a User Equipment, UE, in an end-to-end, E2E, multi-hop sidelink radio communication (81).

The RLC layer functionality providing a plurality of ingress and egress RLC channels for transferring data packets. The method comprising receiving (83), by the RLC layer functionality, data packets a tan ingress RLC channel, mapping (84), by the Adapt layer functionality, data packets received at the ingress RLC channel to an egress RLC channel in accordance with a mapping rule for destining the data packets while maintaining the specified QoS, and transferring (86), by the RLC layer functionality, the mapped data packets at the egress RLC channel.

A service is utilized by a wireless communication device (10). For this service, the wireless communication device (10) simultaneously maintains a first data path (21) and a second data path (22) to a wireless communication network. The first data path (21) has a first QoS level, and the second data path (22) has a second QoS level that is different from the first QoS level. The wireless communication device (10) selects one of the first data path (21) and the second data path (22) for transmitting content of the service while the other of the first data path (21) and the second data path (22) is maintained in an inactive state.

In a first aspect, a communication control method includes establishing, by a relay node, a radio backhaul link for relaying communication between user equipment and a donor base station, for a cell managed by an upper node, and performing, by the relay node, an RRC re-establishment process in order to re-establish the radio backhaul link in response to detecting a failure related to the upper node. The performing the RRC re-establishment process includes identifying a non-selected cell by use of cell information acquired from a lower node of the donor base station or the relay node, and performing an exclusion process for excluding the non-selected cell from targets for which the radio backhaul link is to be re-established.

A communications method includes: A control node determines first configuration information, where the first configuration information belongs to a configuration information set, the configuration information set includes at least one piece of configuration information, and the first configuration information is used to indicate whether a first slave node performs, in some or all of time units included in a preset time period, an operation corresponding to the first configuration information. This is applicable to coordination and management of communication between slave nodes in a transmission system having a plurality of service requirements, and implements flexible configuration of each slave node in the transmission system by the control node.

A communication apparatus capable of performing wireless communication with another apparatus by simultaneously using a first link and a second link performs, based on reception, from a first other apparatus, of a predetermined frame for executing communication by simultaneously using the first link and the second link, transmission, to the first other apparatus, of information indicating allocation of radio resources in the first link and the second link to the first other apparatus, and transmission, to a second other apparatus different from the first other apparatus, of information indicating allocation of the radio resources in one of the first link and the second link to the second other apparatus.
