摘要： A method is disclosed for reducing handover failure probability in cellular networks which includes the steps of determining whether a mobile subscriber is traversing a pre-handover zone defined in each cell of the network, reserving a free channel in an adjacent cell for the mobile subscriber traversing the pre-handover zone, and granting the free channel to the mobile subscriber upon entering a handover region extending across the boundary of the adjacent cells provided that a free channel is available at such a time, and in the alternative, if a free channel is not available at such a time, the handover request is queued until a free channel becomes available.

摘要： The present invention relates to the solution of sets of linear equations by microprocessors. In particular, when the process for solving a set of linear equations can be resolved into a set of tasks, each of which can be processed by a processing element in a multiprocessor computer, embodiments of the present invention determine the scheduling of the processing of respective tasks by each processing element. In an exemplary embodiment, the order in which each processing element should process those tasks distributed to it is determined by computing a cost metric indicative of the amount of time required to process the task and a completion time metric, indicative of the amount of time required to process all remaining tasks after that task is completed. Consequently, the tasks distributed to a given processing element are processed in an order based on the completion time metrics computed for the respective tasks.

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 technique for assigning an address (“shadow address”) to a mobile station that is compatible with the layer-2 address on the wireline network which serves the mobile station. The shadow address is then used as a wireline identifier for the destination address for frames ultimately destined for the mobile station. The shadow address is stored in a watch list for serving base stations, and any base station receiving a frame with a shadow address in its watch list process the frame to forward it the to mobile station. In this way, the shadow address facilitates carrying out soft handoff and smooth handoff.

摘要： A method and system is provided for periodically and dynamically updating allocation pools of IP address which are reserved for wireless or wireline hosts. A system IP address server controls an entire address pool, contains predictive analysis logic, performs a predictive analysis, partitions the IP addresses into distinct address pools, and maintains “wireless guard bands” of IP addresses for wireless users to ensure that a higher priority address pool is never exhausted before an address pool which has a lower priority.

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： Method and apparatus for dynamically allocating IP addresses in a wireless IP network. IP address servers determine the requisite IP address pools and guard bands for individual network cells to guarantee fair access to the network and facilitate handoff host handoff from a prior cell to a new cell. IP address servers also prioritize handoff and resident hosts that request an IP address from the IP address server. In particular, IP address servers assign a higher priority to handoff hosts over resident hosts that request an IP address from an IP address server in order to maintain a preestablished handoff host network connection instead of dropping a handoff host connection in favor of a new resident host network connection. Finally, each cell is allocated a minimum number of IP addresses to ensure a certain level of fair access to the network regardless of the cell wherein a handoff or resident host resides.
摘要翻译：在无线IP网络中动态分配IP地址的方法和装置。 IP地址服务器确定各个网络小区所需的IP地址池和保护频段，以保证对网络的公平访问，并促进从先前小区到新小区的切换主机切换。 IP地址服务器还优先处理从IP地址服务器请求IP地址的切换和驻留主机。特别地，IP地址服务器分配更高的优先级，以便通过从IP地址服务器请求IP地址的常驻主机切换主机，以便维护预先建立的切换主机网络连接，而不是丢弃切换主机连接以利于新的驻留主机网络连接。最后，每个小区被分配最小数量的IP地址，以确保一定程度的公平接入网络，而不管切换或驻留主机所在的小区。
