Abstract: A system is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device. The communications device establishes the radio bearer via a base station of the communications system and communicates data using the established radio bearer. The communications device determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device then provides information to the network entity identifying a result of said determination for use in determining whether the radio bearer should be maintained or released.

Abstract: A communication system (100) is disclosed which uses system frames of a first and a second type. In a system frame of the first type communication with a mobile telephone (3) is subject to a restriction and in a system frame of the second type communication with said mobile telephone (3) is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone (3), in a current system frame, in dependence on whether the current system frame is a first type of system frame or a second type of system frame.

Abstract: A core network node for mobility management includes a means for transmitting information related to expected mobility of user equipment, UE, to an access network node.

Abstract: A method for facilitating allocation of network resources to at least one slice in a communication network includes obtaining information identifying a mapping between network resource allocations and a respective quality of experience (QoE) associated with a user and obtaining information relating to a quality of service (QoS) tolerance for a particular QoE. The method includes providing to a controller for allocating at least a portion of the network resources to the at least one slice: i) the information identifying a mapping between network resource allocations and a QoE; ii) the information relating to the QoS tolerance; and iii) information identifying a current QoE and a target QoE associated with at least one user.

Abstract: User equipment performing communication with a core network node by using network slices obtained by logically dividing a network includes: means for sending information related to security of one network slice; and means for sending identity information of the one network slice in a secure method, based on a request to send information in the secure method sent from the core network node based on the sent information.

Abstract: A method is performed by a user equipment (UE). The method includes transmitting, to a network, a message for registration of the UE. The message comprises information related to one or more network slices that are not compatible with at least one allowed network slice.

Abstract: A wireless terminal can communicate with a first network of first type and a second network of second different type. The wireless terminal performs a packet-domain attachment to the first network and initiates a ready timer indicating that the wireless terminal is in an attached state and has recently sent data to the first network. The wireless terminal initiates an inter-system change from the first network to the second network whereby the wireless terminal becomes registered to the second network. Advantageously the wireless terminal has means for rendering the ready timer ineffective when the inter-system change is performed. The network apparatus has means for initiating its own ready timer dependent on the attachment occurring, this ready timer also indicating that the wireless terminal is in an attached state and has recently sent data to the first network.

Abstract: A system (1) is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device (2). The communications device (2) establishes the radio bearer via a base station (5) of the communications system (1) and communicates data using the established radio bearer. The communications device (2) determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device (2) then provides information to the network entity identifying a result of said determination for use in determining whether the radio bearer should be maintained or released.

Abstract: A communication system (100) is disclosed which uses system frames of a first and a second type. In a system frame of the first type communication with a mobile telephone (3) is subject to a restriction and in a system frame of the second type communication with said mobile telephone (3) is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone (3), in a current system frame, in dependence on whether the current system frame is a first type of system frame or a second type of system frame.

Abstract: A method performed by a node for an Operations, Administration and Management (OAM) system includes maintaining information relating to at least one service provided by at least one node of the OAM system. The information is provided to a management function coupled to the OAM system. In this regard, the node communicates with the management function for sharing the information.

Abstract: A core network node includes a transmitter configured to transmit a control plane data back-off timer to restrict a request from a UE for data transmission via Control Plane CIoT EPS Optimization.
