Abstract: Embodiments herein relate to, e.g., a method performed by a source access node relating to handover of a UE. The source access node sends to a target access node, an initial handover preparation message with a first explicit indicator for the target access node to request an enhanced Make-Before-Break Handover. The source access node receives an handover preparation response message from the target access node, with a second explicit indicator accepting or rejecting the requested enhanced Make-Before-Break Handover. Further, the source access node selects a possible fallback mechanism, upon reception of the handover preparation response message from the target access node indicating rejection or no support of enhanced Make-Before-Break Handover.

Abstract: A method performed in a User Equipment, UE, for handling handover from a source access node to a target access node is provided. The UE receives (501) a handover command message from the source access node. The handover command message includes parameters required for deriving a security context associated with the target access node. The UE establishes (502) a radio connection with the target access node. When detecting (503) that a security context switching criterion is fulfilled, the UE stops (504) to use a security context associated with the source access node.

Abstract: A method performed by a User Equipment, UE, to perform handover from a source access node to a target access node is provided. The UE, the source access node and 5the target access node are operating in a wireless communications network. The UE receives (601) a handover command message from the source access node. The UE establishes (602) a target radio connection with the target access node, and determines (603) whether or not a source cell release criterion is fulfilled. When the source cell release criterion is determined to be fulfilled, the UE releases (604) a source radio 10connection with the source access node.

Abstract: A process allows a UE to acquire an SEN before accessing a target base station/node during a RACH-less handover. The SEN may be provided to the UE in various ways. For example, the SEN may be provided as part of a handover command message (e.g., RRCReconfiguration) or a master information block (MIB). In this manner, the UE acquires the SEN before accessing the target base station/node, which allows the target base station/node and the UE to effect certain timings for the handover. For example, the target base station/node and the UE may set time bounds in which the handover must occur. As another example, different types of uplink grants may be set.

Abstract: A method performed by a source access node for performing data forwarding at handover of a UE from a source cell to a target cell in a wireless communications network is provided. When a criterion for data forwarding is fulfilled, the source access node obtains a trigger for downlink data forwarding. When receiving the trigger, the source access node initiates downlink data forwarding to the UE via the target access node.

Abstract: Systems and methods for cell selection, reselection and camping are provided. A network node transmits cell broadcast information including a cell reservation indication and a cell reservation exception indication. A wireless device receives cell broadcast information and determines if the cell is reserved for selection. The cell can be selected, and camped on, in accordance with the wireless device being associated with the cell reservation exception indication.

Abstract: Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station.

Abstract: A method performed by a target access node for handling data packets in a handover of a User Equipment, UE, from a source cell served by a source access node, to a target cell, served by the target access node in a wireless communications network is provided. The target access node receives a status report of last received data packet in the UE from the source access node. The target access node performs a data packet duplication check based on the information comprised in the status report. The target access node then sends to the UE, only data packets which have not already been received by the UE from the source access node, based on the outcome of the duplication check.

Abstract: A method in a user equipment (UE) (110) is disclosed. The method comprises obtaining (1301) a primary barring configuration (906) for access control in a wireless communications network. The method comprises obtaining (1302) a secondary barring configuration (912) for access control in the wireless communications network. The method comprises determining (1303), based on the primary barring configuration and the secondary barring configuration, whether an access attempt by the UE in the wireless communications network is barred.

Abstract: A method by a wireless device is provided to perform access barring. The method includes starting (1402) a barring timer when an access attempt is barred and, based on a change in barring information (1404), the barring timer is stopped. Alleviation of access barring may be performed when the barring timer is stopped.

Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.
