    Abstract: In some example embodiments, there may be provided a method comprising: receiving, from a first network node in a network via a service-based interface, an update request comprising at least one context information for at least one user equipment in the network and a context key, wherein the at least one user equipment is in a radio resource control connected state; storing or updating the at least one context information at the radio access network data storage function; receiving a retrieve request from a second network node in the network, wherein the retrieve request comprises the context key; retrieving the at least one context information for the at least one user equipment in response to the retrieve request from the second network node based at least on the context key; and sending the at least one context information to the second network node. Related systems, methods, and articles of manufacture are also disclosed.

    Abstract: In some example embodiments, there may be provided a data storage function for handling user equipment context information. In some example embodiments, there may be provided a method that includes receiving, from a first network node via a service-based interface, at least one context information for at least one user equipment in a radio resource control inactive state; storing and/or updating the at least one context information; receiving a retrieve request from a second network node via the service-based interface, wherein the retrieve request comprises a context key; retrieving the at least one context information for the at least one user equipment in response to the retrieve request based at least on the context key; and sending the at least one context information for the at least one user equipment to the second network node via the service-based interface. Related systems, methods, and articles of manufacture are also disclosed.

    Abstract: Various example embodiments relate to relate to network nodes (20A; 20B), methods and computer program products configured to hand over a communication link between a cell and user equipment (10) in a wireless communication network from a source cell (40A) to a target cell (40B; 40C). According to various, but not necessarily all, embodiments of the invention there is provided a node (20A), comprising: means configured to establish a communication link between a source cell (40A) and user equipment (10); means configured to transmit a series of data packets to the user equipment (10), each data packet comprising an associated sequence identifier; means to receive an acknowledgement of successful receipt of a data packet of the series by user equipment (10), the acknowledgement comprising an indication of the successfully received data packet sequence identifier; means configured to receive an indication of an identified handover target cell (40B; 40C); means configured to request handover of the user equipment (10) to the identified handover target cell (40B; 40C); means configured to receive an acknowledgement of handover request from the identified handover target cell (40B; 40C); and means to forward data packets to be transmitted to user equipment (10) to the identified target cell (40B; 40C), the forwarded data packets comprising the indication of associated sequence identifier and the most recent successfully received data packet sequence identifier. Also provided is a node (20B), comprising: means configured to receive a request for handover of user equipment (10) from a source cell (40A) to a target cell (40B; 40C); means configured to transmit an acknowledgement of handover request to the source cell (40A); and means to receive forwarded data packets forming a series of data packets to be transmitted to user equipment (10), the forwarded data packets comprising an indication of a sequence identifier associated with each forwarded data packet and an indication of a most recent successfully received data packet sequence identifier. Arrangements recognise that one way to mitigate some of the negative effects associated with early data forwarding, for example, the increased use of network memory and the risk of duplicate transmissions, is by providing a mechanism supported by a source (20A) and target node (20B) to allow a target access node (20B) to perform efficient data discarding.

    Abstract: A network node comprising at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: transmitting a request to a plurality of nodes to prepare one or more cell candidates; receiving an indication from at least one of the plurality of nodes indicating a capacity to prepare one or more further cell candidates; and transmitting, to one or more of the at least one of the plurality of nodes, a further request to prepare at least one further cell candidate.
