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： 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。

摘要： An arrangement including a scannable matrix for predicting the occurrence of a future collision of frequency hops of the channel hopping patterns on the respective activated first paths of a Bluetooth packet transmission system is described. A first coordinate of the matrix defines columns representative of a selectable window of N successive future time slots of the channel hopping patterns, and a second coordinate of the matrix defines rows each exhibiting the successive frequency hops of the patterns segments transmitted on a separate one of the activated channels during such window. The first coordinate is scanned to detect the occurrence, if any, of identical frequency hops appearing at an intersection of the then-scanned column and at least a pair of the rows. If a particular scan does not detect an occurrence of such identical frequency hops in any of the time slots of the scanned window, the first coordinate may be incremented by a selected number of time slots at the end of the scan, and the scan is then successively repeated for each new window that results. If and when identical frequency hops are detected in a particular future time slot during a scan, the channel hopping pattern(s) on a subset of the affected channels may be suitably altered to avoid the predicted collision.

摘要： A Bluetooth-enabled terminal having a radio manager for minimizing frequency collisions between channel hopping patterns transmitted over plural channels established between such terminal and correspondent Bluetooth devices is described. The radio manager extracts successive sets of projected future N—time slot segments of the respective Bluetooth channel hopping patterns. Each extracted set is tested to detect a time slot, if any, where frequency hops of the segments of the set coincide, indicating a frequency collision. When a collision time slot is detected, the radio manager generates a marker which triggers an alteration of the frequency hops that would otherwise be exhibited by a subset of the generated channel hopping patterns in such detected time slot. Such terminal may optionally be provided with an additional network interface to define a collision-resistant Bluetooth access point.
