A method performed by a base station for operating a data throughput counter in a wireless communications network is provided. The method includes determining a number of data throughput values over a determined period of time, wherein each determined data throughput value represents the data throughput associated with data transferred during a Radio Resource Connection, RRC, connection or part thereof. The method also includes incrementing the data throughput counter based on those determined throughput values for which the amount of data transferred is above a first threshold value, and/or for which the transport time of said amount of data is above a second threshold value. A base station for operating a data throughput counter in a wireless communications network is also provided, as well as computer programs and carriers.

Filtered user equipment throughput counter

A method and a status manager for controlling status reporting from a data receiving node in a wireless communication of data with a data sending node. When detecting that the data receiving node should transmit a status report to the data sending node before a prescribed time limit expires, the data receiving node is triggered to transmit the status report either together with data if the data is pending for transmission from the data receiving node when the time left before the prescribed time limit is greater than a minimum duration, or alone if no data is pending when the time left before the time limit becomes shorter than the minimum duration.

Method and status manager for controlling status reporting in wireless communication data

An application executed on a plurality of wireless communication devices () measures a performance indicator. The application sends reports () of the performance indicator to a server (). On the basis of the reports (), the server determines a rate of reporting the performance indicator and sends an indication () of the rate of reporting to the application executed on at least some of the wireless communication devices (). According to the indicated rate of reporting, the application on these wireless communication devices controls a timing of measuring the performance indicator and sending the reports () to the server ().

Rate control for application performance monitoring

To relieve signaling congestion, UEs () having delay-tolerant data are moved more rapidly to the non UL synchronized state, freeing up PUCCH resources for users that have not indicated a delay-tolerance. In one embodiment, a resource conservative mode is defined for a UE () having delay-tolerant data (e.g., from a 'background' app); otherwise, the UE () assumes a default mode. In one embodiment, the network sends the UE a pair of first and a second values (or indices to them) for a Time Alignment Timer, TAT () in the UE (). The first value&#x2014;which is typically smaller than the second value&#x2014;is used by the UE () in the resource conservative mode when the user data plane is internally concluded as being delay-tolerant or has already been confirmed to be delay-tolerant; the second value is used otherwise (i.e., in default mode). In the resource conservative mode, the shorter TAT value moves the UE from PUCCH more rapidly, and the UE () uses random access for infrequent scheduling requests. In the default mode, the UE () retains PUCCH and has low latency for scheduling requests. The network may preconfigure the pair of TAT values. The mechanism is furthermore capable of achieving a synchronized start of a TAT value, and also stopping any TAT () that is running.

Inactivity handling of devices with delay-tolerant traffic

A radio communication handling device handling communication for an application running in a mobile station and communicating with an application server via a mobile communication network includes a radio resource determination unit that determines a state transition for the radio resources between the mobile station and the mobile communication network from a first current state to a second state, where the first state involves communication with a higher bandwidth than the second state, and informs, prior to the transition, at least one application communication control unit about the transition in order to allow the application communication control unit to release unused application communication connections before the transition. The application communication control unit receives the information about the following state transition and determines whether to release an application communication connection or not based on the information.

Radio efficient TCP release

A method of controlling streaming of data, such as video, from a streaming server to a User Equipment (UE) via a Radio Access Network (RAN) is provided. The method includes receiving streaming data from the streaming server, re-shaping the received streaming data into bursts, and transmitting the bursts to the UE. The bursts are transmitted at a higher bitrate than the bitrate of the received streaming data. By re-shaping the streaming data into bursts, streaming can be effected in a more radio-friendly way, since the UE may switch to a less resource consuming radio state in-between reception of data bursts delivered at high bitrates. Further, a corresponding computer program and computer program product, and a proxy unit for controlling streaming of data from a streaming server to a UE via a RAN, are provided.

Controlling streaming of data from a streaming server to a user equipment via a radio access network

The present invention is related to a method of securing integrity and authenticating origin and privileges of a piece of code. According to the invention, a method of securing integrity and authenticating origin and privileges of a piece of code in a communication network by digitally signing said piece of code, is characterized by the steps of: providing an aggregator (C), which is a holder of a valid signing certificate, &#x2014;submitting a developer material to the aggregator, inserting a revocation code into the developer material, building a complete piece of code using the developer material and the revocation code, digitally signing the complete piece of code using the certificate held by the aggregator, making the digitally signed complete piece of code retrievable to the holder (B) of the developer material, providing a server (C) for authenticating privileges of the digitally signed complete piece of code, &#x2014;executing the revocation code and checking with the server whether the privileges of the digitally signed complete piece of code have not been revoked.
