  • Patent number: 9456380
    Abstract: A method and apparatus for handling data compression in a mobile communication network. A node located between a mobile terminal and a mobility anchor point determines compression information relating to data transferred between the node and the mobile terminal. The node then sends the compression information to a network repository node for storage and retrieval by a further node in an event that subsequent mobility of the mobile terminal leads to transferring data between the mobile terminal and the further node.

  • Patent number: 9432050
    Abstract: A method of updating data compression software. The method comprises using real-time data to train upgraded compression/decompression software. A compressor and/or decompressor function processes and delivers the real-time data using an existing compression/decompression software. Following completion of the training process, the compressor and/or decompressor deactivates the existing compression/decompression software and activates the upgraded compression/decompression software to process and deliver the real-time data.

  • Patent number: 9386597
    Abstract: A method of delivering packets from a radio access network to a user terminal. The method comprises establishing a radio access bearer for transporting data to the user terminal from a radio layer control entity responsible for constructing downlink radio frames. Within the radio access network, an IP traffic flow destined for said user terminal is observed and a delivery priority determined for the IP traffic flow taking into account a user application to which the traffic relates. The delivery priority is dynamic ally adjusted in dependence upon the desired arrival time or delivery rate of packets within the IP traffic flow at the user terminal. With respect to other downlink user traffic to be sent over the radio interface, packets of the IP traffic flow are scheduled for transmission to the user terminal over the established radio access bearer, and or the scheduling weight of radio frames of the established radio access bearer adjusted, in accordance with the current delivery priority.

  • Patent number: 9369934
    Abstract: A method in a network node for handling a cache session between the network node and a user equipment during a handover of the user equipment from a source cell of a first RAT to a target cell of a second RAT being different from the first RAT is provided. The user equipment and the network node are comprised in a wireless communications system. The network node receives (704) an identifier. The identifier identifies a cache session in the network node. The cache session is associated with a play-out for a media stream to the user equipment via a source base station serving the user equipment in the source cell. The network node identifies (705) the cache session as pertaining to the user equipment subject to said handover, by means of the received identifier. The network node then continues (708) the identified cache session via a target base station serving the target cell, when the handover of the user equipment from the source cell to the target cell has been performed.

  • Publication number: 20160164791
    Abstract: Method in and a network node (160; 110; 401a, 600) for congestion management of a transport network (130) comprised in a wireless communications network (100). The wireless communications network (100) further comprises a base station (110; 401a) configured to receive data being transported via a data transport path (132; 404a,d) of the transport network (130) and to transmit the received data to one or more wireless devices (120) served by the base station (110; 401a). The network node obtains (302; 409; 501) an indicator indicating at least a risk for occurrence of downlink data congestion in the data transport path (132; 404a,d). To reduce said at least risk, the network node then controls (304; 411; 502) the base station (110; 401a) to reduce and/or limit a throughput rate of data being transmitted to the one or more wireless devices (120). The data is received by the base station (110; 401a) via the data transport path (132, 404a,d).

  • Patent number: 9271216
    Abstract: A method and apparatus for sending user plane traffic via a node located between a base station and a Serving Gateway in a mobile telecommunications network. The base station receives a message containing tunneling protocol information identifying the Serving Gateway. It sends a second message towards the node, the second message including tunneling protocol information identifying the base station and the Serving Gateway. The base station receives a third message from the node, the third message including tunneling protocol information for the base station to use towards the node, and tunneling protocol information for the Serving Gateway to use towards the node. A fourth message is sent, which includes tunneling protocol information for the Serving Gateway to use towards the node. User plane traffic can then be sent between the base station and the Serving Gateway via the node.
