    摘要: Aspects of the invention provide a method and system for managing or coordinating data transmission in a Local Area Network (LAN) such that Quality of Service (QoS) concerns are met. A LAN resource manager (LRM) is provided for managing the LAN resources by providing solutions for providing users with several levels of QoS. Once the LRM admits a user at a certain QoS level, the level is assured within the LAN for as long as the user is in the LAN. A user may submit a request to transmit data to the LRM. The LRM may determine if time allocation is possible and allocate the time slots for data transmission. The LRM may send time slot allocation information to an Access Server in a LAN, which may inform the user of the time slot allocation and prepare a queue according to the slot allocation information.

    摘要: A method and system for dynamic forward assignment of IP addresses in a wireless network wherein a serving base station requests IP addresses of it neighboring cells. The serving base station then provides the requested IP addresses to the mobile stations it serves based on whether the mobile station will be entering a particular neighboring cell. Immediately upon entering the neighboring cell the mobile station establishes over the air communications with the neighboring cell's base station using one of the requested addresses. In another embodiment of the present invention each mobile unit is responsible for attaining IP addresses from the base stations of neighboring cells. Accordingly, the base stations serve as relay points for the IP address requests from the mobile unit to an address server.

    摘要: A Multi-Interface Mobility Management (MIMM) client is provided on a mobile Multi-Interface Device (MID) to support seamless network connectivity and switching of the MID. The MIMM client communicates with a MIMM Server. The MIMM Server collects information from MIMM Clients and provides information to the MIMM Clients pertaining to the network(s) to which the mobile MID has access, such as information concerning the availability of a network, the quality of network connectivity, etc. The MIMM Client is responsible for determining whether and when a handoff or roaming operation should be initiated by the mobile MID, and which network interface the mobile MID should use after the handoff/roam operation has been completed. The MIMM Client also is responsible for performing mobility-related functions that are required prior and subsequent to the handoff/roam operation. The MIMM Client uses the information received from the MIMM Server in order to make these determinations.

    摘要: A method of controlling a communication network including VC exchange nodes and VP exchange nodes such that the cell flow of each VP can be maintained within the prescribed characteristic while the end-to-end cell transfer quality for VCs can be estimated easily and accurately. In the network, a cell transfer from the VC exchange nodes to the VP exchange nodes is controlled within prescribed traffic characteristics specified to VPs; a cell transfer quality at each of the VC exchange node is specified in terms of a first cell transfer quality dependent on the control of the cell transfer, and a second cell transfer quality independent on the control of the cell transfer: a cell transfer quality at each of the VP exchange node is specified by a third cell transfer quality independent on the control of the cell transfer alone; an end-to-end cell transfer quality for each VC in the network is estimated in terms of the cell transfer quality of each of the VC exchange nodes and the cell transfer quality of each of the VP exchange nodes: and the bandwidth management in the network is carried out such that the estimated end-to-end cell transfer quality becomes higher than a desired quality of service.
