摘要： At least portions of the map of the base stations, i.e., which base stations are neighbors, is discovered and updated using a wireless terminal controlled handoff process. The portion of the map that is discovered by a particular base station is typically its neighbors to which -it can possibly hand off a call it is serving. It takes at least one handoff with each such base station neighbor for the particular base station to discover its entire local map, i.e., all the base stations to which the particular base station can perform handoffs. The wireless terminal handoff process is used to supply a base station with information about other base stations with whom the base station can cooperate to perform handoffs. The handoff process may subsequently be performed more expeditiously between the particular base station and such other base stations using the obtained information. As part of the handoff process, the wireless terminal tells the new base station to which it is handing off the call the identity of the previous base station from which control is being handed off. The wireless terminal then completes handoff and begins to be served by the new base station. If the new base station does not have a valid record for the previous base station, it forms a trust relationship with the previous base station and creates a record for it, thus identifying it as a neighbor to which it can perform expedited handoff in response to the control of a wireless terminal.

摘要： A simplified network, i.e., a network with reduced hierarchy from a control point of view, e.g., one that only requires home location register and base station network entities along with interconnection therefore, may be employed with a minimal decrease in performance, e.g., a minimal increase in delay, during the handoff process. In one embodiment of the invention, a first base station which initially receives a service request from a wireless terminal requests authentication information from a central security node and receives in response at least, one, but typically two or more, sets of security information. When it is time for a handoff from the first base station to a second base station, the first base station transmits to the second base station at least one of the sets of security information it received from the central security node. The second base station then uses the information it received from the first base station to authenticate the wireless terminal.

摘要翻译：使用无线终端控制的切换过程来发现和更新基站的映射的至少部分，即哪些基站是相邻的。由特定基站发现的地图的一部分通常是其邻居，可以切断其正在服务的呼叫。与特定基站的每个这样的基站邻居需要至少一次切换，以发现其整个局部映射，即特定基站可执行切换的所有基站。无线终端切换过程用于向基站提供关于基站可以与其合作执行切换的其他基站的信息。随后可以使用获得的信息在特定基站和其他基站之间更快速地执行切换过程。作为切换过程的一部分，无线终端向新基站通知其正在将呼叫转移到从其转移控制的先前基站的身份。无线终端然后完成切换并开始由新基站服务。如果新的基站不具有先前基站的有效记录，则它与先前的基站形成信任关系并为其创建记录，从而将其识别为可以响应于该基站进行加急切换的邻居控制无线终端。

摘要： The defined boundaries in a network are pushed down to the base station level. Doing so necessitates authentication each time a wireless terminal switches communication, or "handoffs" from one base station to another. To achieve such authentication in an efficient manner, security information, i.e., the derived information, is transferred from one base station directly to another. By directly it is meant without accessing any other source of the derived information, although the information may be transferred via other intervening nodes of the network that form an interconnection path for the base stations. A simplified network, i.e., a network with reduced hierarchy from a control point of view, e.g., one that only requires home location register and base station network entities along with interconnection therefore, may be employed with a minimal decrease in performance, e.g., a minimal increase in delay, during the handoff process. In one embodiment of the invention, a first base station which initially receives a service request from a wireless terminal requests authentication information from a central security node and receives in response at least, one, but typically two or more, sets of security information. When it is time for a handoff from the first base station to a second base station, the first base station transmits to the second base station at least one of the sets of security information it received from the central security node. The second base station then uses the information it received from the first base station to authenticate the wireless terminal.
摘要翻译：网络中定义的边界被下推到基站级别。这样做需要每次无线终端切换通信或从一个基站“切换”到另一个基站时进行认证。为了以有效的方式实现这种认证，安全信息，即派生信息，从一个基站直接转移到另一个基站。通过直接意图是指不访问任何其他来源的导出信息，尽管信息可以通过形成基站的互连路径的网络的其他中间节点传送。可以采用简化的网络，即从控制角度降低层级的网络，例如仅需要归属位置寄存器和基站网络实体以及互连的网络，其性能的最小降低，例如，在切换过程中延迟的最小增加。在本发明的一个实施例中，最初从无线终端接收服务请求的第一基站从中央安全节点请求认证信息，并且响应于至少一个但通常为两个或更多个安全信息的集合来接收。当是从第一基站到第二基站的切换的时候，第一基站向中央安全节点接收的安全信息集合中的至少一个传送给第二基站。然后，第二基站使用其从第一基站接收的信息来认证无线终端。
