A method, system and apparatus for group management for vehicle-to-anything (V2X) and Proximity Based Services (ProSe) groupcast. According to one aspect, a method in a wireless device (WD) includes discovering wireless devices (WDs) that are members of a group, and sending to the WDs that are members of the group a group discovery complete message. According to another aspect, a method in a WD includes listening for a group discovery signal indicating a group to which the WD belongs or seeks to join, and sending a group discovery response indicating that the WD seeks to join or remain in the indicated group.

Group management for V2X groupcast

A method performed by an agent for handling an event of a network service deployed in a cloud environment is provided. The agent is capable to access to a server in the cloud environment. The agent obtains information from the server. The information is about an event of the network service. When the network service relates to a Third Generation Partnership Project (3GPP) network, the agent decides whether to register network service with or without an associated address of a load balancer of the network service. The agent then registers in a core network node operating in the 3GPP network, the network service with or without an associated address of a load balancer of the network service according to the event and according to the outcome of the deciding.

Agent, server, core network node and methods therein for handling an event of a network service deployed in a cloud environment

The invention relates to an access manager, and a method performed by the access manager of transferring data in a wireless communication system comprising a control plane distributed over at least one first site and over at least one second site, wherein a session manager is arranged in the control plane of the second site and the access manager is arranged in the control plane of the first site, the first site being remote from the second site and located physically closer to a radio access network of the wireless communication system.

5G core network optimized local handover

The invention relates to a method for enabling relocation of a function for processing data packets of a flow associated with a device. The method is performed in an arrangement of a communication system, which is allocated as a proxy for control messages exchanged between an instance of the function for processing the data packets of the flow and a control instance controlling how the function processes the data packets of the flow. The method comprises obtaining () information indicating that the function for processing the data packets is relocated from a first instance to a second instance. The method further comprises forwarding () control messages received from the control instance to the second instance of the function for processing the data packets and vice versa, in response to the obtained information.

Method and apparatus for relocating packet processing functions

The invention relates to a method in an arrangement of a communication network, controlling a function for processing data packets of a flow associated with a device. The method comprises determining () to relocate the function for processing the data packets from a source instance to a target instance for the device, controlling () transmission of an instruction to the source instance to relocate the function for processing the data packets to the target instance, and controlling () an update of a switching element in a chain of functions for processing the data packets of the flow comprising said function. The switching element affects the routing of the data packets of the flow in the chain. The switching element is updated with information related to the relocated function. The invention also relates to a method performed by the source instance and to the arrangement and the source instance.

Method and arrangement for relocating packet processing functions

The invention relates to a method in an arrangement of a communication network, controlling a chain of functions for processing data packets of a flow associated with a device. The method comprises obtaining () an indication indicating that information associated with a context of at least one of the functions has been altered. The context is related to the flow and at least one of the communication network, the device, a route of the flow, and a source instance of each of the at least one function. The method further comprises determining () to relocate the at least one function for processing the data packets from the respective source instance to a respective target instance based on the obtained indication. The method also comprises relocating () the at least one function for processing the data packets to the respective target instance.

A method and apparatus for use in a communications network in which a Mobile Node accesses the communications network via a proxy node. The proxy node is arranged to handle mobility signalling on behalf of the Mobile Node. At a mobility anchor function, such as a Local Mobility Anchor, a first Care-of-Address associated with the Mobile Node is registered. When the mobility anchor function receives a registration request to register a second Care-of-Address associated with the Mobile Node, it sends a request message to the proxy node acting on behalf of the Mobile Node. The request message instructs the proxy node to check whether the Mobile Node is reachable using the first Care-of-Address.

Method and apparatus for use in a communications network

Methods and apparatuses for combining internet protocol layer authentication and mobility signaling are disclosed. Various embodiments for providing authentication and mobility signaling when a mobile node moves from a 3GPP access network to a non 3GPP access network and vice versa are described.

Method and apparatus for combining internet protocol authentication and mobility signaling

In a communication system including mobile terminals and different wireless networks the mobile terminals can estimate the speed with which the mobile terminals move and communicate estimated values of the speed to a selection function () selecting one of the wireless networks communicating information from and to the respective mobile terminal. In the estimating, first estimated speeds and/or positions of a mobile terminal are determined () particularly for each of the wireless networks, from the communication with the particular wireless network. Then the estimated values are by special interfaces () input to a different speed estimation function () in which a combined value of the speed of the mobile terminal is calculated, according to a speed estimation algorithm and is input to the selection function. In this speed estimation also a recommended one of the wireless networks can be determined. The functions for estimating the speed are divided between a network layer (L3) and lower layers (L2, L1).
