    • Reconnection of a mobile unit to a call session controlled by a first MSC is supported responsive to a network-initiated or mobile-originated reconnect attempt even in instances where the mobile unit has roamed to a border cell controlled by a second MSC. In a network-initiated reconnect attempt, the first MSC sends a suspended call page request to a second MSC. The second MSC pages the mobile unit, sets up a bearer channel to the mobile unit, and sends to the first MSC a suspended call page response including indicia of the bearer channel set up by the second MSC. The first MSC establishes a bearer channel to the second MSC thereby reconnecting the mobile unit to the call session. In a mobile-originated reconnect attempt, the mobile unit sends a mobile-originated reconnect message to the second MSC. If the second MSC does not find session information associated with the call, it sends a suspended call handoff request to the first MSC causing the first MSC to query a database to find indicia of the call session, establish a bearer channel to the second MSC and send to the second MSC a suspended call handoff acknowledgement including information associated with the call session. The second MSC establishes a bearer channel to the mobile unit thereby reconnecting the mobile unit to the call session.
    • 即使在移动单元漫游到由第二MSC控制的边界小区的情况下,也支持将移动单元重新连接到由第一MSC控制的呼叫会话,所述呼叫会话由网络发起或移动发起的重新连接尝试来支持。 在网络发起的重新连接尝试中,第一MSC向第二MSC发送暂停的呼叫寻呼请求。 第二MSC向移动单元寻址,向移动单元建立承载信道,并向第一MSC发送包括由第二MSC建立的承载信道的标记的暂停的呼叫寻呼响应。 第一MSC建立到第二MSC的承载信道,从而将移动单元重新连接到呼叫会话。 在移动发起的重新连接尝试中,移动单元向第二MSC发送移动发起的重新连接消息。 如果第二MSC没有找到与呼叫相关联的会话信息,则向第一MSC发送暂停的呼叫切换请求,使第一MSC查询数据库以查找呼叫会话的标记,建立到第二MSC的承载信道, 向第二MSC发送包括与呼叫会话相关联的信息的暂停呼叫切换确认。 第二MSC建立到移动单元的承载信道,从而将移动单元重新连接到呼叫会话。
