摘要:
In a mobile network comprising a plurality of base stations and a gateway, a user equipment may perform a handover from a source base station to a target base station. By control signalling, the handover may be notified from the target base station to a control node of the mobile network and then to the gateway so that the gateway may switch to a data path which connects the target base station and the gateway. The notification of the handover may be delayed at the target base station or at the control node, by starting a timer and sending the control signalling for initiating the path switching after expiry of the timer.

A method is provided of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, each carrying data packets that relate to different ones of a plurality of services. In the method bandwidth profiling is applied to the data packets of each bearer, independently of the other bearers, to identify and mark the data packets of each of the bearers that are conformant with a predetermined maximum information rate for the bearer. The data packets are forwarded for transport through the transport network, wherein, if there is insufficient bandwidth available in the transport network to transport all data packets, data packets not identified by the profiling as being conformant are discarded, so as not to be transported through the transport network.

A method of prioritizing packets for delivery over a transport network, where a guaranteed minimum information rate over the transport network is specified. The method comprises, for each bearer to be injected into the transport network from the mobile network, specifying a bearer information rate and marking packets up to that rate as conformant with the bearer information rate, and marking packets exceeding that rate as non-conformant. Multiple traffic-type streams from the mobile network are converged, each traffic-type stream comprising multiple bearers. Packets of traffic-type streams are inspected to identify packets marked as conformant and non-conformant, and at least a fraction of non-conformant packets are re-marked as conformant if the converged rate of conformant packets is less than said minimum information rate. The transport network prioritizes delivery of packets marked as conformant over those packets marked as non-conformant.

A system for providing simultaneous local and global connectivity for a 3rd generation partnership project user equipment (3GPP-UE) includes a connectivity service function (CSF) module communicating with a 3GPP-UE, a residential gateway (RGw) connected to the CSF and to consumer premises equipment (CPE) and a mobile access gateway (MAG) connected to the CSF via a level 2 (L2) tunnel, to the RGw via a broadband remote access server (BRAS) and to a packet data network gateway (PDN-GW) via a proxy mobile internet protocol (PMIP) tunnel.

A technique for routing one or more service tunnels in a telecommunications backhaul network (110) is provided. The telecommunications backhaul network has a first routing path (132) and a second routing path (134). As to a method aspect of the technique, data of the one or more service tunnels is transmitted on the first routing path (132). A reduction in transmission capacity is detected on the first routing path (134) by means of a first routing path condition. The first routing path condition indicates a state of the first routing path (132). A second routing path condition is determined indicating a state of the second routing path (134) in response to the detected reduction in transmission capacity on the first routing path (132). It is decided upon rerouting one or more of the service tunnels from the first routing path (132) to the second routing path (132) based on both the first routing path condition and the second routing path condition.
摘要:
A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as ‘green’ data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum ‘green’ buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a ‘green’ data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as ‘green’ data packets are discarded, so as not to be transported through the transport network.

A method of allowing a nomadic terminal to access a home network on the Layer 2 level. The method comprises connecting said terminal to a remote access network via an access point, the remote access network being connected to an operator's backbone network via a remote access router. Signalling is exchanged between the access point and an authentication server within the backbone network in order to authenticate the terminal to the authentication server and, following successful authentication, a Layer 2 tunnel extending across the backbone network is established for the purpose of connecting said nomadic terminal to the home network.
摘要:
A method and apparatus for packet scheduling over a communication link in a communication network. A data packet scheduler accords scheduling weights to at least two sets of data packets to be transmitted, and the sending of the sets of data packets is scheduled in accordance with the scheduling weights. When it is determined that a change in available bandwidth over the communication link has occurred, the scheduler dynamically adjusts the scheduling weight for each set of data packets on the basis of the available bandwidth. This ensures more efficient resource sharing control and resource guarantees when the available bandwidth changes.
