摘要： Method and device(s) for supporting estimation of latency over a communication path in a communication network between a data flow shaping node, providing a data flow in bursts towards a data flow target node, and a probe node. The devices(s) initiate to transmit, by the data flow shaping node, a sample burst being a burst of said bursts that differs in a predefined manner from preceding and subsequent bursts so that the data flow target node in response to the sample burst transmits a certain pattern of acknowledgement packets that differs compared to patterns of acknowledgement packets transmitted by the data flow target node in response to said preceding and subsequent bursts. The device(s) initiates to identify, by the probe node, receipt of potential acknowledgement packets according to said certain pattern.

摘要： A method performed by a communication device in a network comprising mobile networks operated by mobile network operators, MNs, is provided. The method includes signaling to a first server to discover a second server having information about a public land mobile network identifier and a network service of a MNO. The second server has a first fully qualified domain name, FQDN, pointing to a provider domain. The method further includes receiving a response including a resolution or a redirection of the FQDN; signaling to discover the information about the network service; and receiving a response from the second server including a first identification of the information about the network service of the MNO or a second identification that the network service is not available. Corresponding methods performed by a first server and a second server are also provided.

摘要： Methods and apparatus are provided for processing communications. In one aspect, a method in a first node in a network of delivering content comprises delivering a first portion of the content to a device, receiving a request for a second portion of the content from the device and, responsive to the request and responsive to a determination that the second portion of the content should be delivered to the device from a second node in the network, instructing the device to retrieve the content from the second node.

摘要： A method and a device proxy for handling radio communication of content data from a data source to be played out on a media player of a wireless device in a wireless network. When detecting that a potential data class is available, the device proxy fetches segments of the content data from the data source over a potential data bearer dedicated for data of said potential data class. The potential data bearer is dedicated for data of the potential data class, which is less sensitive to delay than data of other data classes. The potential data bearer is also less costly to use compared to other data bearer(s). The fetched segments of content data are stored by the device proxy in an intermediate buffer, and the segments of content data are delivered from the intermediate buffer when requested by the media player.

摘要： There is a provided herein a proxy at a border between two transport domains, the proxy arranged to deliver packets to a communications device in a first transport domain; the packets received from a server in a second transport domain. The proxy is arranged to: receive a packet from the server, the packet directed to the communications device; and forward the packet to the communications device and reply to the server with a traffic handling offer message, the traffic handling offer message including a plurality of traffic handling options. The proxy is further arranged to receive a selection of a traffic handling option from the server; and apply the selected traffic handling option to packets sent from the server to the communications device via the proxy.

摘要： A method of performing multi-path load balancing in a communications network comprising a plurality of servers comprises, in a server: receiving a first connection request from a first load balancer, sent from a first interface of a client device (step 301); and storing a code representing the server in a database, the code associated with a unique identity of the server (step 302). The method comprises, in a second load balancer: receiving a second connection request, from a second interface of the client device, wherein the second connection request is associated with the first connection request sent from the first interface of the client device to the server, and wherein the second connection request includes a code associated with the server (step 401); mapping the code to an entry in the database (step 402); determining the unique server identity associated with the code (step 403); and forwarding the second connection request to the server associated with the unique server identity (404).

摘要： A method of operating a UPF in a wireless communication system includes receiving a data packet, identifying a PFCP session context associated with the data packet, determining whether a PDR associated with the PFCP session context should be modified or a new PDR should be created, transmitting a request to a session management function to provision a new or modified PDR at the UPF, receiving a session modification response from the SMF provisioning the new or modified PDR for the PFCP session context at the UPF, and applying the new or modified PDR on the data packet.

摘要： A method executed by an Intermediary Node arranged between a Client and a Server for participating in the setting up of a connection between the Client and a Server is described. In response to intercepting a first message, the method transmits from the Client and destined for the Server, and requests for a connection to be set-up between the Client and the Server. The method recognizes, based on content of the received first message, that it is desirable for the Intermediary Node to perform at least one function on the requested connection, the Intermediary Node is transmitting a second message to the Client, comprising an identity of the Intermediary Node. This enables the Client to accept or reject the Intermediary Node as a node participating in the requested connection set-up.

摘要： Methods and device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) for managing Round Trip Time, RTT, associated with provision of a data flow (150; 250) from a server device (130; 230), via a multi-access communication network (100; 200), to a client device (120; 220). Said device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) being communicatively connected to the multi-access communication network (100; 200) that is configured to provide the data flow (150; 250) to the client device (120; 220) using a resource of the multi-access communication network (100; 200) that is shared by multiple devices (120-121; 220-221). The device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) initiates, in response to identification that the data flow (150; 250) belongs to a certain type, introduction of an artificial delay in the RTT.
