    Abstract: A procedure is disclosed where a user equipment (UE) 10 can share information (with e.g. radio access network (RAN) nodes 20, 30) about its cell mobility attempts (e.g. redirection successes/failures). This information can subsequently be utilized by the various RAN nodes 20, 30 when making subsequent, i.e. future, cell mobility decisions. Hereby it is made possible to improve cell mobility decisions, such as redirection or handover, by the various RAN nodes 20, 30.

    Abstract: A communication network and techniques related to the handover of a terminal device between radio access nodes in the communication network are disclosed. In some communication networks (e.g., LTE communication networks), the ability to quickly move or resume a user equipment (UE) session between cells becomes increasingly important. In situations where the encryption and integrity keys are derived from a base key of a primary cell (PCell), each time the UE moves from that PCell or reconnects in another PCell a key renegotiation must be performed before traffic can resume. This may also involve buffering, decrypting and re-encrypting already encrypted packets. In turn, this consumes considerable processor cycles and memory, complicates the implementation of the network, and causes delays that reduce the end-user experience. These problems are solved by the disclosed techniques and communication network which provide improvements in the way in which security is handled when a handover occurs between two evolved NodeBs (eNBs) of the communication network. According to an aspect, there is provided a method of operating a first radio access node in a communication network, the method comprising determining (601) whether a first base key that is used to determine a first encryption key for encrypting communications between a communication device and the first radio access node can be used by a second radio access node for determining a second encryption key for encrypting communications between the communication device and the second radio access node; and if the first base key can be used by the second radio access node, sending (603) the first base key to the second radio access node during handover of the communication device from the first radio access node to the second radio access node. A radio access node and a communication device adapted for implementing the method are also disclosed.
