摘要： A method, User Equipment (UE), and first base station serving a first cell for performing an access request by the UE for operatively connecting the UE to a second cell. The UE obtains radio quality parameters indicating quality of radio reception between the UE and the first and second cells. Based on the obtained radio quality parameters, it is determined whether the UE is in a link imbalance zone where the UE has an option to be connected to both the first cell and the second cell. If so, the UE sends access request information, to the first base station and indicates availability of the UE to be redirected to the second cell. The first base station may redirect the UE to the second cell when a load of the first cell meets pre-defined load criteria.

摘要： The present invention relates to a method and a network node for selecting a gateway for a user equipment in a communications system. The communications system comprises the network node and one or more gateways, configured to provide packet data network connectivity to the user equipment. The network node detects (401) the presence of local gateways among said gateways and obtains (403) a first set of information indicating the type of the user equipment. Based on the first set of information, the network node selects (406) one of the detected local gateways to provide packet data network connectivity to the user equipment when the user equipment type is of a fixed type.

摘要： A method and a radio node (RN) shared by operators of separate cellular networks having operator specific tracking area plans. The radio node (RN) broadcasts (1:1) system information with network identities of the cellular networks (PLMN IDs) and multiple operator specific tracking area codes (TACs) valid in respective tracking area plans of the cellular networks, each tracking area code being associated with a corresponding network identity in the system information. Thereby, the operators are enabled to use their own operator specific tracking area codes for their respective operator specific tracking areas that include a cell (100) covered by the radio node.

摘要： A method and network node for selecting a most suitable gateway for a User Equipment (UE) located in a wireless communications network. The network includes the network node and at least two gateways configured to provide packet data network connectivity to the UE located within a served cell. The network node detects a presence of a local gateway among the gateways and obtains UE information including a type of the UE. The UE type is either a stationary/fixed type or a mobile type, and the UE type is determined based on UE mobility behavior in relation to a local gateway service area. The network node selects the detected local gateway or another gateway among the at least two gateways for providing packet data network connectivity to the UE based on the determined UE type.

摘要： A communications network (20) that comprises packet core network entity (22) and a heterogeneous radio access network (23). The heterogeneous radio access network (23) comprises plural base station nodes, including at least one macro base station node (28M) and at least one low power base station node (28L). The packet core network entity (22) generates a list (30) of tracking areas using an indication of cell type (32M) for the macro base station node and an indication of cell type (32L) for the low power base station node. The list (30) generated by the packet core network entity comprises the tracking area for the macro base station node and the tracking area for the low power base station node. In an example embodiment the indication of cell type indicates whether the cell served by the respective base station node is a macro cell or a low power cell.
