Abstract: A UE (10) provides information on potential S?eNB(s). The information is forwarded from an MeNB (20_1) to an M?eNB (20_2) such that the M?eNB (20_2) can determine, before the handover happens, whether the M?eNB (20_2) will configure a new SeNB (S?eNB) and which S?eNB the M?eNB (20_2) will configure. In one of options, the MeNB (20_1) derives a key S?-KeNB for communication protection between the UE (10) and the S?eNB (30_1), and send the S?-KeNB to the M?eNB (20_2). In another option, the M?eNB (20_2) derives the S?-KeNB from a key KeNB* received from the MeNB (20_1). The M?eNB (20_2) sends the S?-KeNB to the S?eNB (30_1). Moreover, there are also provided several variations to perform SeNB Release, SeNB Addition, Bearer Modification and the like, in which the order and/or timing thereof can be different during the handover procedure.

Abstract: A method for performing a performance measurement on a multipoint packet flow transmitted in a packet-switched subnetwork. A monitoring network of measurement points is implemented in the subnetwork. All packets have a marking value, which is periodically switched between first and second marking values. Each measurement point receiving a marked packet updates a couple of performance parameters, one per each marking value. Since not all the measurement points receive the same packets of the multipoint packet flow, to provide a performance measurement a cluster of measurement points is firstly identified in the monitoring network, which possesses the following property: each packet received at the input of the cluster is also received at the output of the cluster, if no packet loss occurs. The performance parameters provided by input and output measurement points of the identified cluster are then used for providing the performance measurements.

Abstract: Methods, systems, and devices for wireless communication are described to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If the semi-persistent resources are not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in collisions between the scheduled traffic and the priority traffic.

In some aspects, the SIP node may store the neighbor SIP node configurations to a data store for formatting subsequent SIP messages exchanged between the SIP node and the neighbor SIP node.
