摘要:
A method for mitigating buffering delay in a TCP- encapsulated data stream transmitted over a network, the method comprising conducting the following steps at a node (200) in said network: receiving a first packet through a first interface (241), said first packet comprising data of said TCP- encapsulated data stream; receiving a second packet through a second interface (211), said second packet comprising an acknowledgment of segments of said TCP - encapsulated data stream; analyzing said first packet and said second packet to estimate an amount of outstanding data; using said amount of outstanding data to determine a state of buffer occupancy; updating a TCP Window field in said second packet in function of said state of buffer occupancy, and transmitting said updated second packet through said first interface.

A method is disclosed for routing packets in an intermediate node between a mobile node and a correspondent node in a packet-switched network, only one of said nodes being macro- mobility enabled, comprising at the intermediate node: - exchanging lower-layer-address-update-related messages with said macro-mobility enabled node; - mapping source address, destination address and potentially protocol parameters of lower-layer packets exchanged between the mobile node and the correspondent node in such a way that the macro-mobility enabled node can communicate with the other node as if the other node is also macro-mobility enabled, and such that the other node can communicate with the intermediate node as if the intermediate node is a non-macro-mobility-enabled node. Also associated devices, update methods for devices, and servers are disclosed.

Example embodiments provide methods for handling the transition of a mobile device from a first network to a second network, the second network operating according to a different communications protocol from the first network. One example embodiment includes terminating forwarding of the data packets from the first network to the mobile device; rebuilding headers of unforwarded data packets at the first network; and sending the rebuilt data packets from the first network to the second network. Another example embodiment includes resetting a header compression state at the second network; receiving unforwarded data packets from the first network at the second network, the unforwarded data packets being data packets the first network had not yet forwarded to the mobile device; and sending the unforwarded data packets from the second network to the mobile device.

摘要:
In a processing system comprising a processor and a plurality of peripherals coupled to the processor, access privileges of a secure operating mode of the processor are delegated to at least a given one of the peripherals. The given peripheral is configured to store, in a secure portion of that peripheral, state information indicative of the processor being in a secure operating mode. The given peripheral is further configured to utilize the stored state information to allow the given peripheral to access at least one resource that is accessible to the processor in the secure operating mode but is not otherwise accessible to the given peripheral. The processing system may comprise, for example, a system on a chip, wherein the processor and peripherals are combined into a single integrated circuit.

A method in one example has: establishing communication between two mobile terminals in a base station routing architecture network; and optimizing routing between the two mobiles terminals without requiring all traffic to traverse an anchor point in the base station routing architecture network. An IP base station transceiver architecture utilizes network controlled mobility to provide a transparent connection between a mobile terminal and an anchor point in the network. This transparency hides the mobility associated with changing IP base station transceivers from the mobile terminal and reduces over-the-air signaling.

Disclosed is a system and method for transmitting a data packet from a source to a destination via a network path having a number of hops. The sum of a playback delay associated with the data packet and the number of hops are stored in a header of the data packet. The data packet is transmitted from the source to the destination via the network path.

Network equipment of a wireless communication system comprises a backhaul interface for communicating with a broadcast-based backhaul network and an air interface for communicating with a plurality of mobiles. The network equipment is configured to serve as a proxy on the broadcast-based backhaul network for at least a given one of the mobiles that communicates with the network equipment over the air interface, by determining an IP address for the given mobile and sending a broadcast message over the broadcast-based backhaul network advertising itself as the proxy in association with the IP address. The network equipment may comprise at least a portion of a base station of the wireless communication system. The broadcast-based backhaul network may comprise a local area network that operates in accordance with an Ethernet protocol, and the air interface may comprise an LTE air interface or a WiMAX air interface.

The invention pertains to a method for providing access to a mobile communication network comprising at least one base transceiver station, wherein the communication network is being visited by a piece of user equipment having a home operator in a home network. The method comprises at the base transceiver station: receiving a channel request from said user equipment, creating a virtual machine associated with said home operator of said user equipment, establishing a channel using said virtual machine, and allocating channel resources of said at least one base station to accommodate said channel. The invention also pertains to a base station system to carry out the method of the invention.
