摘要:
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.

The invention includes a method and apparatus for reconfiguring a first base station element to attempt to serve at least a portion of the plurality of wireless terminals served by a second base station element in response to detection of a failure condition at a second base station element that was serving the plurality of wireless terminals prior to the occurrence of the failure condition.

A method for mitigating buffering delay in a TCP-encapsulated data stream transmitted over a network includes, at a node in the network, receiving a first packet through a first interface. The first packet includes data of the TCP-encapsulated data stream. A second packet is received through a second interface. The second packet includes an acknowledgment of segments of the TCP-encapsulated data stream. The method further includes analyzing the first packet and the second packet to estimate an amount of outstanding data, using the amount of outstanding data to determine a state of buffer occupancy, updating a TCP Window field in the second packet in function of the state of buffer occupancy, and transmitting the updated second packet through the first interface.
摘要:
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.

A method of synchronizing with an uplink channel and a method of determining a propagation delay in a wireless communications system are provided. In the example method of synchronizing, a propagation delay between a target base station and a mobile station is calculated. Then, the calculated propagation delay is sent to the target base station. In the example method of determining a propagation delay, a first signal is received indicating a first measured chip offset between a downlink channel of a serving base station and a pilot signal of the target base station. A second signal indicating a second measured chip offset between an uplink channel of the mobile station and a pilot signal of the target base station is then received. A propagation delay between the target base station and the mobile station is calculated based at least in part on the first and second measured chip offsets.
摘要:
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.
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.
摘要:
An active set of base stations may be controlled based on whether data is unavailable at base stations within the active set. The base station may transmit an indicator indicating whether data is unavailable at the base station and/or a mobile station may monitor a channel characteristic of at least a portion of a channel between the base station and the mobile station.
