摘要:
A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover.

The present invention relates to a method for use in a user equipment (10), and relates to a user equipment (10) for enabling a serving base station (40) to estimate interference contribution in a network when scheduling resources for the use equipment. According to the method, the user equipment determines an amount of resources required to send data and the user equipment sends a report to it serving base station when the required amount of resources is greater than a threshold value. In the report, measurements performed by the user equipment are included. The report will assist the serving base station with its estimation of the degree of interference user equipments generates in the network, and hence the power and resources to assign.

A method in a first radio network node for handling position measurements is provided. The first radio network node receives from a second radio network node a position measurement associated with a user equipment, and a system frame number. The system frame number is associated with the second radio network node. The system frame number is further related to a point in time when the position measurement was performed. The first radio network node calculates a position estimate of the position of the user equipment based on the position measurement. The first radio network node defines a time stamp which is based on the received system frame number. The first radio network node then signals to a third radio network node a positioning response. The positioning response comprises the position estimate and the time stamp.

A method and apparatus for managing UE-based network performance measurements utilizing a process of tracing a UE in a radio telecommunication network. An eNB may receive a trace activation message from a Mobility Management Entity, MME, or a Network Management Entity, wherein the trace activation message includes eNB-specific, and optionally MME-specific, selection conditions for selecting a UE for a trace session. The eNB selects a UE for tracing when the eNB-specific selection conditions are satisfied, and may send the MME-specific selection conditions to the MME for evaluation. When all selection conditions are satisfied, the eNB activates the trace session with the selected UE. The Trace Activation IE utilized in the Trace Start message, the UE Context Setup Request message, and the Handover Request message is extended with additional IEs in order to implement the method.

摘要:
A method and arrangement for handover wherein the handover resource (the dedicated random access preamble) is reserved by the target radio base station (RBS) for a limited period of time, thus increasing the handover efficiency and thereby allowing random access preambles to be used for initial access to a larger extent. The information about the reserved time interval is sent to the UE in the handover command message by means of a frame number offset between the source RBS and the target RBS. The UE uses the information to calculate when to send its synchronisation message to the target RBS. The frame number offset is calculated either by source RBS or by target RBS.

The present disclosure relates to a technique for configuring and collecting network performance measurements in a mobile communications network, the mobile communications network comprising at least one network node and at least one mobile terminal 208 connected to the at least one network node, implementing a Minimization of Drive Tests (MDT) trace measurement configuration and collection. A method embodiment comprises the steps of performing, in the at least one mobile terminal 208, a service specific measurement based on a service specific measurement configuration, wherein the service specific measurement includes determining one or more quality metrics related to at least one of one or more services, one or more service types, one or more bearers, one or more applications and one or more application types provided in the mobile communications network, to obtain a result of the performed service specific measurement and generating, in the at least one mobile terminal 208, active test traffic based on an active measurement configuration to perform an active measurement, wherein the active measurement uses the generated test traffic to obtain a result of the performed active measurement, the result of the performed active measurement indicating the performance of the test traffic in the mobile communications network.
摘要:
In existing mobile networks, users may be traced to troubleshoot problematic user connections, monitor generic network performance, and to perform root cause analysis to identify network problems. However, the existing tracing methods provide incomplete trace information. To address this and other issues, early tracing recording is enabled in which an involved trace entity starts recording the trace data when any initial activity related to the user equipment is detected. The trace entity can continue the trace if a trace trigger is later confirmed or may discard the trace data if the trigger is not confirmed.

The present invention relates to methods and arrangements for handling UE capability information a mobile telecommunications network wherein an eNodeB (100) receives (60) information regarding the UE capability information from the UE (120) and stores (70) the information. The eNodeB (100) sends (80) the UE capability information to the EPC, i.e. the MME (130). The MME (130) receives and stores (90) the UE capability information. When the UE (120) transits from idle to active state, does an initial attach or when a part of the UE capabilities have changed, it sends (10) a message Ma to the eNodeB (100) regarding the update. The eNodeB (100) receives the message and sends (20) it to the MME (130). The MME (130) sends (30) a response associated with the previously stored UE capability information to the eNodeB (100). The eNodeB (100) decides (40) if the UE capabilities stored in the MME (130) is up-to-date based on the message sent from the UE (120) and the received response from the MME (130). If the UE (120) holds updated UE capabilities the eNodeB (100) could request (50) updated UE capability information from the UE (120).
