The physical paths may be represented to the IP network as a logical path comprising one or more virtual IP nodes. | 2011-09-29 |
20110235574 | ASSIGNMENT SCHEME FOR WIRELESS NODE IDENTIFIERS AND LOCATION CODES - A method including receiving a geographic area value limit that segments a geographic region associated with a network into geographic areas; receiving a geographic area-level evolved Node B (eNB) value limit that indicates a maximum number of eNBs to reside in each geographic area; calculating eNB identifiers based on the geographic area value limit and the geographic area-level eNB value limit; assigning the eNB identifiers to eNBs associated with the network; receiving a tracking region value limit that segments the geographic region associated with the network into the geographic areas; receiving a tracking area value limit that indicates a maximum number of tracking areas within each geographic area; calculating tracking area codes based on the tracking region value limit and the tracking area value limit; and assigning the tracking area codes to the tracking areas within each geographic area. | 2011-09-29 |
20110235575 | Signaling Message Prioritization - Methods, system, and articles are described herein for receiving and prioritizing a plurality of signaling messages based at least on classifications of the signaling messages. At least a number of the signaling messages are processed in order of priority, the number processed being based at least on a volume of the signaling messages. | 2011-09-29 |
20110235576 | ENHANCED CARRIER SENSING FOR MULTI-CHANNEL OPERATION - In various embodiments, a multi-channel request-to-send and a multi-channel clear-to-send may be used in a wireless communications network to assure that a subsequent multi-channel communications exchange between two devices takes place only over channels that are sensed by both devices as being free. | 2011-09-29 |
