Abstract: Various communication systems can benefit from signaling optimization. For example, communication systems including fourth generation (4G) and fifth generation (5G) networks may benefit from network signaling optimization for light connected mode. A method can include identifying, by a device, that a user equipment has left an area. The method can also include starting, by the device, a suspend procedure for the user equipment based on identifying that the user equipment has left the area.

Abstract: Radio resource allocation for proximity services There are provided measures for radio resource allocation for proximity services. Such measures exemplarily comprise receiving a message including a service request and indicative of a demand of a proximity service, detecting said demand of said proximity service from said message, and preventing, based on said demand of said proximity service, a transmission of an end entity context related to said service request.

Abstract: Various communication systems may benefit from an identifier that can correlate a user equipment or a packet data network connection with a particular cell. For example, a correlation identifier may be useful to address management of user plane congestion and other use cases. A method can include generating a correlation identifier for a user equipment and/or a packet data network connection. The method also includes the ability to identify the user context information with the same correlation ID in the core network and in the radio access network. The method can also include sending the correlation identifier to a network element.

Abstract: There are provided measures for enabling/realizing FRER support of a wireless communication system operable as a TSN bridge, such as e.g. FRER support of a 5GS TSN bridge. Such measures exemplarily comprise configuration of a wireless communication system operable as a TSN bridge, such as e.g. a 5GS TSN bridge, for supporting FRER functionality, wherein parameters relating to a stream identification function and at least one of a stream splitting function and a sequence recovery function are extracted from a FRER configuration, at least one network entity is identified, and FRER-related configuration information is provided for the identified at least one network entity, including at last part of the extracted parameters, for enabling realization of the stream identification function and the at least one of the stream splitting function and the sequence recovery function.

Abstract: Methods, apparatuses, and computer program products provide for specifying, in quality of service (QoS) requests, alternative QoS-related parameter sets and/or alternative traffic pattern parameter sets. In the context of one method, the method receives a QoS request comprising one or more QoS parameters and/or one or more traffic pattern parameters, and one or more alternative QoS parameter sets and/or one and more alternative traffic pattern parameter sets. The method also selects the one or more QoS parameters or an alternative QoS parameter set of the one or more alternative QoS parameter sets based on a supporting capability of a network. The method also causes transmission of a Policy and Charging Control (PCC) rule based on the selected parameters and transmits an indication of the selected parameters.

Abstract: Various communication systems may benefit from a dynamic streaming service. For example, certain streaming services may benefit from an improvement in the switching between broadcast delivery and unicast delivery for a streaming service in a cellular system. A method includes receiving information about a streaming service. The method also includes determining by a network entity in a radio access network whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information. In addition, the method includes triggering a sending of the data via the multimedia broadcast or the unicast.

Abstract: Various communication systems may benefit from an improved signaling protocol. For example, machine-to-machine communications in a network may benefit from improved signaling and security. A method includes establishing a secure data transmission path for an application. The secure data transmission path is used to transmit data between a user equipment and a network element. The network entity includes a gateway or an application server. The method also includes transmitting data for the application over the secure data transmission path using a pre-configured radio bearer. The radio bearer is pre-configured for data transmission between the user equipment and an access node located between the user equipment and the network element. In addition, the method includes receiving a response message at the user equipment from the network element through the secure data transmission path.
