摘要： Provided are methods for handling reports on lost connections in a terminal device which is capable of being in communication connection with a plurality of network access nodes, wherein the terminal device generates, after having lost connection to a (first) network access node, a report on the loss of connection and, upon or after reconnecting of the terminal device with the same or a different network access node, sends the report on the loss of connection to the network access node. The network access node receiving a report on loss of connection from a terminal device, forwards said report to a central server and/or to a network access node to which the terminal device was connected before. Further provided are a terminal device comprising a receiver and a transmitter and being adapted to connect to an access node of a network, particularly of a wireless, e.g. a cellular radio network, said terminal device further comprising a report generator for generating a report on a loss of connection, wherein said transmitter is adapted to send said report to an access node upon or after reconnecting, and a network access node, particularly a network access node of a wireless, e.g. a cellular radio network, comprising a receiver and a transmitter and being adapted to be connected by a terminal device, wherein the receiver is adapted to receive reports on a loss of connection from a terminal device, and wherein the transmitter is adapted to forward or send a received report to a central server or to a different access node, particularly to an access node to which the terminal was connected before a loss of connection.

摘要： A method in a radio network node for identifying a candidate cell for handover of a user equipment is provided. The radio network node receives, from the user equipment, a first cell identifier associated with the candidate cell. The radio network node signals a cell identification request to at least one base station serving a cell using the first cell identifier. The cell identification request comprises a user equipment identifier associated with the user equipment (102), and requests any cell wherein the user equipment associated with the user equipment identifier can be detected. The radio network node receives a cell identification response comprising a second cell identifier associated with a detecting cell, served by a detecting base station, wherein the user equipment associated with the user equipment identifier is detected. The radio network node then identifies the candidate cell based on the received second cell identifier.

摘要： An authentication mechanism renders a communications network impervious to unauthorized requests for interaction termination or cessation. In a release authentication mode of operation, the authentication mechanism protects against an unauthorized connection release message directed to a mobile node (30) of the network, e.g., a mobile station such as a user equipment unit, thereby thwarting an attempt to request an unauthorized connection release procedure concerning a connection involving the mobile node. In a detach authentication mode of operation, the authentication mechanism protects against an unauthorized detach message deceptively transmitted on behalf of a mobile node, thereby thwarting an attempt to request an unauthorized detach procedure for the mobile node. In its modes of operation, the authentication mechanism involves a first node (Ni) of the communications network at which authentication key is provided. The first node of the network uses the authentication key to derive an authentication indicia related to the authentication key. The first node (Ni) provides the authentication indicia to a second node (Nr) of the network. Subsequently, when an interaction termination operation is to occur (e.g., connection release or detach), the first node includes the authentication key in an interaction termination message transmitted over an air interface between the first node and the second node. As a condition for performing an interaction termination operation, the second node (Nr) confirms that the authentication key (which was included in the interaction termination message) is, in fact, related to the authentication indicia.
