摘要： A method in a network node for improving transmission control protocol, TCP, performance in a cellular network is provided. The network node handles TCP packet transferral between a user equipment and a server in the cellular network. The user equipment and the server are configured to adapt a retransmission timeout setting based on round trip times for performed TCP packet transferrals. When the network node obtains an indication of a handover outage being upcoming for the user equipment, the network node deliberately delays, in a time period preceding the indicated handover outage, a transferal of a TCP packet between the server and the user equipment to increase the round trip time for the TCP packet.

摘要： The present solution relates to enabling improved performance for a user equipment UE (205) in a communication network (200). A network node (210) detects (301, 401) that wireless performance between the UE (205) and a base station (201) is poor. Then, it identifies (302,402) a location of the UE (205) where the poor performance is detected, obtains (303,403) an identity associated with the UE (205), obtains (304,404) an address associated with the UE (205) and identifies (305,405) that the location of the UE (205) is residential and that the address corresponds to the location. The node (210) searches (306,406) for a wireline connection (219) located within a distance from the UE (205). The node (210) establishes (307,407) whether the performance for the UE (205) would be improved by providing services from a core network (209) to the UE (205) via the wireline connection (219) using the home base station (215).

摘要： A technique for controlling and handling set up of a probe tunnel stretching from an access network node through a core network towards a core network node is described. In a method implementation, probe tunnel set up control comprises determining a First Fully Qualified Tunnel Endpoint Identifier (F-TEID) associated with the core network node and sending a probe tunnel set up instruction to the access network node. The instruction commands the access network node to locally set up the probe tunnel towards the core network node based on the F-TEID.

摘要： The invention provides a method by which a network element in a telecommunications network can report factors that have limited the performance of a UE in an observation period. A bottleneck score is calculated for each factor, the bottleneck score providing a measurement of the extent to which that factor has limited the performance of that UE compared to other factors in the observation period A data record for the UE is populated with the bottleneck scores and sent in a report towards upper layer management functions. When these reports are received (e.g. by a MME) they may be complemented with global entities of the users and aggregated measures created. The bottleneck scores may be calculated by collecting per-UE performance counters from a radio scheduler and estimating an actual UE performance from the collected performance counters, replacing one or more of the measured performance counters with a hypothetical value reflecting a particular factor operating ideally, and estimating a theoretical user performance based on the hypothetical value and remaining performance counters, and assigning a bottleneck score for that factor by comparing the estimated actual user performance with the estimated theoretical user performance.

摘要： The invention relates to a method of performing cell selection for a set of mobile terminals among at least two neighbouring cells comprising a first and a second radio access node, respectively. The method comprises acquiring a value of at least one property reflecting a network condition for each one of the mobile terminals, determining with which one of the first and second radio access nodes each of the mobile terminals initially should be associated based on the value of the acquired property for each mobile terminal,and generating a plurality of variations to the determined initial association based on a corresponding selected parameter. The method further comprises performing cell selection for at least a subset of the generated plurality of variations to the initial association, and determining a value of a metric for each of the performed cell selections and associating each metric value with said acquired property and the selected parameters for each corresponding variation of each performed cell selection, which metric reflects a performance for the set of mobile terminals for each performed cell selection, wherein cell selection subsequently can be performed based on the metric value and the associated acquired property and selected parameters.

摘要： In oneaspect of the teachings herein, an Application Function, AF, in a wireless communication network is configured to support online charging for the consumption of content that has been pre-fetched to a wireless device via the network. The AF functionality thus provides a mechanism by which content may be pre-fetched to a wireless device in advance of charging for that content, while reliably conditioning the later consumption of that content at the wireless device on the online charging decisions made by an online charging system. In another aspect, a wireless device is configured to send a consumption request for pre-fetched content towards such an AF and condition its consumption of the pre-fetched content on the consumption response returned to it.
