Abstract: A network device processes packets transiting the device using successive deep packet inspection (DPI) rules. For each rule, the device attempts to apply the DPI rule to each packet, applies the DPI rule to each packet for which the attempt is successful, determines a probability that the attempt is successful across a plurality of packets, determines an average computational cost of applying the rule across a plurality of packets, and determines a merit of the DPI rule based on the average computational cost and the probability. The device reorders the successive DPI rules in an order of decreasing merit (computational cost), and processes new packets using the optimized DPI rules. The method of re-arranging DPI rules provides significant saving for network devices including mobile gateways in terms of computational cost.

Abstract: A base station has a transmission element to wirelessly transmit at least one data frame. The at least one data frame has a predetermined uplink allocation and a predetermined downlink allocation. A detection element detects a congestion condition. When the congestion condition is detected, the transmission element transmits a request to at least one neighboring base station for an expansion of the predetermined uplink allocation or the predetermined downlink allocation. A reception element receives a signal from the at least one neighboring base station. A processing element expand the one of the predetermined uplink allocation or the predetermined downlink allocation by a specified amount in response to the signal indicating the specified amount for a mutually agreed time, or number of symbols or frames.

Abstract: At least one operating condition is determined for a first mobile subscriber station (104) that is operating in an orthogonal frequency division multiple access (OFDMA) network. The first mobile subscriber station (104) is handed off from a base station (102) to a relay station (110). Based upon the at least one operating condition, at least one sub-channel is subsequently assigned from a plurality of sub-channels of a frequency band to the first mobile subscriber station (104) in order to provide an assigned sub-channel resource to the first mobile subscriber station (104). The assigned sub-channel resource can potentially be any of the plurality of sub-channels of the frequency band.

Abstract: A mobile communications system includes a first base station to service a first set of connections from a first set of mobile communications devices to a communications network. A set of neighboring base stations is in communication with the first base station. In an embodiment of the invention, the first base station prioritizes the first set of connections according to first predetermined criteria and prioritizes the set of neighboring base stations according to second predetermined criteria. The prioritization lists are used in deterministic ways to alleviate potential congestion in backhaul links and optimize the overall performance of system and improved quality of service.

Abstract: A method and system for fast IP handoff of a mobile node (MN) (102) from a first wireless network (106) to a second wireless network (108) is disclosed. The method includes releasing (402) a tunnel between a first access router (AR) (204) and a second FA (206), based on at least one predefined criterion. The method also includes initializing (404) a mobile IP registration procedure with the second FA. The mobile registration procedure is performed by the MN.

Abstract: Various embodiments are described to address the need for an apparatus and method that improves upon known handoff techniques, such as Mobile IP and Fast Mobile IP, to improve the mobility experience of an end user. OSI layer 2-originated indications of a handoff being imminent (301, 501, 502), a link down for handoff (307, 509, 510), and a new link up after handoff (309, 511, 512) are introduced. These indications can be used by applications (such as real-time/streaming applications on the mobile (101)) to take suitable proactive measures prior to an actual handoff. Examples of such measures include the buffering of data to be used during the handoff interval in a way that improves the seamless mobility experience of the end user.

Abstract: In a wireless communication system (106), base stations (118, 120) are connected to a backbone network (116) such as a wired LAN and act as access points and relays for remote stations (128, 132, 136). A remote station registers and performs bidirectional communication with one of the base stations designated as its home base station. Base stations have overlapping coverage areas where a remote station is within reception range of several base stations. Such communication system may for instance be a multicell radio LAN using frequency hopping signaling. The method allows to reuse a limited number of network resources such as frequency hopping patterns and assign the same resource to several active base stations.
