Abstract: A method and arrangement for exchanging service and RAN information. In a communication network a service providing element is enabled to adapt delivery of a service based on RAN-related parameters. The communication network comprises a RAN (Radio Access Network) node, a core network node, and the service providing element. The RAN node obtains a RAN-related parameter and sends the RAN-related parameter to the service providing element via the core network node. The core network node receives the RAN-related parameter from the RAN node, re-structures the RAN-related parameter into a data structure readable by the service providing element, and sends the re-structured RAN-related parameter to the service providing element. The service providing element is configured to receive the RAN-related parameter, and adapt a service delivery parameter based on the RAN-related parameter.

Abstract: To control a TCP congestion window size for data sent from a TCP sending node in a communications network towards a TCP receiving node via a Radio Access Network, the TCP sending node determines a minimum required bit rate for a data stream sent towards the TCP receiving node. It then determines that a sending bit rate of the data stream must be reduced using a TCP congestion avoidance mechanism. When the congestion avoidance mechanism is applied, the congestion window size is adjusted such that the sending bit rate is no lower than the minimum required bit rate.

Abstract: A method for establishing an interaction session on the second communication bearer between an Interaction Gateway (IGW) of a RAN and the service client for controlling the service level communication. The method obtains an initialization message addressed to the RAN by means of default IGW address information on the first bearer, for initiating the interaction session, determines dedicated IGW address information for the interaction session, and initiates sending of a confirmation message comprising the determined dedicated IGW address information to the service client. The method ensures that the interaction session is associated with the second communication bearer used for the service level communication, and obtains an interaction session message addressed to the RAN by means of the determined dedicated IGW address information on the second communication bearer, and further initiates sending a response to the interaction session message, to the service client in the radio device on the second bearer.

Abstract: A method and apparatus for identifying a User Equipment (UE) in a communication network. A service aware control signalling node associated with a transmission path related to the UE receives a first message sent from a Radio Access Network (RAN) node associated with the UE on the transmission path. The first message initiates a communication between the RAN node and the control signalling node and includes an identity of the UE. On its own, the identity of the UE is not enough to unambiguously identify the UE, as described above. The control signalling node stores at a database an identity of the UE and an identity of the transmission path via which the first message was sent. The combination of the UE identity and the transmission path identity can be used to uniquely identify the UE.

Abstract: A method and apparatus for providing information relating to delivery of a service from a server to a mobile device. A node in a Radio Access Network (RAN) receives from an interaction device an instruction message indicating that the mobile device is authorised to exchange service delivery information relating to delivery of the service from the server to the mobile device with the node in the RAN. The node can then exchange service delivery information with the mobile device. The interaction device need not maintain state, as it simply authorises the mobile device to interact directly with the node in the RAN. Furthermore, signalling between the interaction device and the node in the RAN is reduced.

Abstract: According to a first aspect there is provided a method of enabling load steering between a 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) and a Wi-Fi RAN. The method comprises, at a server, generating overlap information associating one or more cells of the 3GPP RAN with one or more Access Points (AP) of the Wi-Fi RAN, wherein a cell of the 3GPP RAN is associated with an AP of the Wi-Fi RAN if it is determined that the cell overlaps with an area covered by the AP.
