A method performed in a communication network, in which the method comprises obtaining a prediction of future available bandwidth of a radio carrier for a service application in a radio device connected to the network. The method also comprises receiving information about a status of an application buffer of the service application. The method also comprises, based on the obtained prediction and on the received buffer information, preparing a recommendation to the service application for when to fill up an application buffer of the service application. The method also comprises initiating sending of a recommendation message comprising the prepared recommendation to the radio device.

Network recommended buffer management of a service application in a radio device

A node () of a cellular network controls sending of first uplink grants to a communication device (). The first uplink grants indicate first uplink radio resources allocated to the communication device () and are sent in response to receiving scheduling requests from the communication device (). Further, the node () controls sending of second uplink grants to the communication device (). The second uplink grants indicate second uplink radio resources allocated to the communication device () and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device () and the configured periodicity of sending the second uplink grants, the node () controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.

Periodic uplink grant alignment in a cellular network

A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.

Network node, a base station for uplink grant pre-allocation

A pre-scheduling grant transmission method performed by a network node includes issuing a first sequence of pre-scheduling grants to provide a UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting data relating to at least transmitted uplink traffic initiated by the first pre-scheduling grants to obtain a data set providing a statistical description of the traffic flow during the time period covered by the first sequence of pre-scheduling grants, predicting from the obtained data set the time when the next data packet arrives to the send buffer of the UE, and transmitting at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time, thereby providing the UE with timely resources for transmitting the data packet shortly after the packet has arrived at the UE send buffer.

Embodiments herein relate to a method in a transmitting radio node () for handling data packets within a radio bearer in a radio communications network (). The transmitting radio node () sets up, within a radio bearer, a logical sub-channel for each of at least two identified packet flows. The transmitting radio node () associates an identity to each data packet of respective identified packet flow, where the identity is indicating the logical sub-channel of the respective identified traffic flow. The transmitting radio node () transfers the data packets of respective identified packet flow in an order over a channel in the radio communications network (), where the order of transferring is based on the identity of each data packet.

Transmitting radio node, a receiving radio node, and methods therein for handling data packets within a radio bearer

A method performed by a communication network node is provided for scheduling of a User Equipment, UE, in a communication network which comprises the UE and the communication network node. The UE is arranged to communicate data on a plurality of bearers with the communication network node. In the method, one or more active bearers among the plurality of bearers are determined, the highest priority of the active bearers are determined, and a data transmission in uplink is scheduled for the UE based on the highest priority. By only taking active bearers in account when scheduling, UEs with non-active high priority bearer are prevented from performing free-riding traffic on lower prioritized bearers.

Preventing free-riding data traffic when scheduling uplink data

A method in a transmitting radio node for scheduling service data flows within a radio bearer towards a receiving radio node in a radio communications network is provided. The transmitting radio node maps data packets of at least two service data flows within the radio bearer to a respective pre-scheduling queue at a PDCP layer, wherein each pre-scheduling queue is associated with a service or a service quality requirement of the respective service data flow. The transmitting radio node further pre-schedules the data packets of the respective pre-scheduling queue down to a scheduling queue at a RLC or a MAC layer. The transmitting radio node further schedules the data packets in the scheduling queue towards the receiving radio node. The transmitting radio node takes a prebuffer time of a data packet queued in the pre-scheduling queue into account when pre-scheduling and/or scheduling the data packets.

Transmitting radio node and method therein for scheduling service data flows

A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.

A communication system, cache, computer readable medium and method for preventing a packet channel in the communication network to time out. The method includes sending data from a cache () to a user terminal (), wherein the cache () is located at an interface device (-); determining that the data is sent to the user terminal () from the cache () without passing a core network (); and generating and sending a dummy message () through the core network () to a device () having an internet protocol, IP, address.

Method for preventing packet channel timing out and system

A node () controls transitions between radio resource control states for a wireless terminal () in a radio access network (). The radio resource control states comprise a first state and a second state. The node () comprises a capacity manager () and a radio resource manager (). The capacity manager () is configured to monitor a network condition of the radio access network (). The radio resource manager () is configured to make a decision whether to make a transition from the first state to the second state by determining whether (1) a cost of remaining in the first state is greater than (2) a cost of switching to the second state, and wherein the radio resource manager is configured to take the network condition into consideration when making the decision.

Dynamic radio resource control state switching

A method of setting up and handing off calls in a mobile cellular radio system in which consideration is given to the load capacity of several types of channels. The communication system determines the available capacity of the different groups of channels in the communication system whenever a new call needs to be set up. The system then assigns the new call to the group of channels with the most available channels if the requesting mobile station is a multi-mode mobile station, or the system hands off a multi-mode mobile station from a first group of channels to a second group of channels or vice versa to create free channels for calls from single mode mobiles.

Method for redistributing dual mode mobile units to extended channel

A method and system for ensuring that handoff requests take priority over new cell requests to engage voice channels assigned to a particular target cell are provided. A certain number of channels are reserved for handoff requests. However, if no channels, reserved or unreserved, are available, handoff requests to a particular target cell are stored in a corresponding queue for a predetermined period of time. Thus, when voice channels become available, they are seized in order to satisfy the handoff requests stored in that queue. If the handoff queue is empty, new call requests to a target cell may be assigned to available voice channels.
