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 UE activates a PS Data Off service to block downlink and uplink services except the exempted services determined by the HPLMN. To activate PS Data Off, the UE sends an indication to the MME or SGSN, or additionally to a S-CSCF or an IMS network. The UE may receive a confirmation of the PS Data Off activation and/or a list of exempt services. The MME may contact the HSS to notify about the activation of the PS Data Off and receive indication of support of the service or list of exempted services and send the indication and/or packet filtering per PDN to PDN GW(s). The PDN GW may contact a PCRF to get policy rules. The HSS may provide a list of exempt services to the S-CSCF.

Abstract: Systems, methods, apparatuses, and computer program products for discovering a network function (NF) acting as a network function service consumer are provided. One method may include, when a NF service consumer subscribes to notifications from a NF service producer, receiving, by the NF service producer, subscription information including a name of a consumer service of the NF service consumer that subscribes to notifications of the NF service producer. The receiving of the subscription information with the name of the consumer service allows the NF service producer to discover a corresponding NF service from an alternative NF instance within a NF set.
