    • A communications system offering telephone number portability services, where a subscriber of a ported telephone number is able to maintain existing voice mail services from an existing end office switching system, independent of the new end office switching system serving the ported telephone number. The end office switching system accessing the voice mail system includes ported number forwarding logic. Using this logic, that office sends a signaling message via a common channel interoffice signaling network. A calling party field of the message specifies the ported telephone number (i.e., the actual called number), instead of the actual calling party number. The end office switching system serving the voice mail system, also referred to as the accessed end office switching system, receives the signaling message, extracts the ported telephone number from the calling party field, and forwards the ported telephone number information to the voice mail system. The information is forwarded to the voice mail system across a data link interface according to a protocol that is independent of any predetermined range of provisioned exchanges.
    • 一种提供电话号码可携带性服务的通信系统,其中移动电话号码的用户能够维护来自现有终端交换系统的现有语音邮件服务,独立于服务于移植电话号码的新的终端交换系统。 访问语音邮件系统的终端交换系统包括端口号转发逻辑。 使用该逻辑,该办公室通过公共信道局间信令网络发送信令消息。 消息的呼叫方字段指定了移植的电话号码(即实际被叫号码),而不是实际的呼叫方号码。 服务于语音邮件系统的终端交换系统(也称为接入终端交换系统)接收信令消息,从呼叫方字段提取移植的电话号码,并将移动的电话号码信息转发到语音信箱系统 。 信息根据独立于任何预定范围的供应交换机的协议通过数据链路接口被转发到语音邮件系统。
