    • A system and method for providing subscriber unit or base station initiated service negotiation in a wireless communication system. Message generators in the mobile switching center, base station, and subscriber unit compose messages to be transmitted in association with the service negotiation, while message processors analyze received messages in order to direct the message generators to compose the appropriate response messages. In a subscriber unit initiated service negotiation, the subscriber unit initiates service negotiation by sending a Service Request Message to the base station containing the requested service configuration. The base station then checks with the mobile switching center to ensure that the requested service configuration is authorized for use by the particular subscriber unit. In a base station initiated service negotiation, the base station determines the appropriate service configuration to be used, and includes it in a Change Service Request message transmitted to the mobile switching center. The mobile switching center checks the service configuration to ensure that it is authorized for the particular subscriber unit. The present invention also provides support for service negotiation during soft handoff. In soft handoff using circuit mode transport for inter base station communication, the new service configuration is presented to all target base stations via the mobile switching center.
    • 一种用于在无线通信系统中提供用户单元或基站发起的服务协商的系统和方法。 移动交换中心,基站和用户单元中的消息发生器组成与服务协商相关联地发送的消息,而消息处理器分析所接收的消息,以指示消息发生器组成适当的响应消息。 在用户单元启动的服务协商中,用户单元通过向包含所请求的服务配置的基站发送服务请求消息来发起服务协商。 然后,基站与移动交换中心进行检查,以确保所请求的服务配置被授权供特定用户单元使用。 在基站发起的服务协商中,基站确定要使用的适当业务配置,并将其包含在发送到移动交换中心的变更业务请求消息中。 移动交换中心检查服务配置,以确保它被授权给特定的用户单元。 本发明还提供了在软切换期间服务协商的支持。 在用于基站间通信的电路模式传输的软切换中,通过移动交换中心向所有目标基站提供新的业务配置。

    • A system and method for providing mobile switching center (MSC) initiated service negotiation in a wireless communication system. If a new call arrives for a subscriber unit while the subscriber unit is already on the traffic channel, a change in the service configuration may allow the subscriber unit to receive the new call while preserving the old call. MSC initiated service negotiation may be used to establish the change in service configuration. The MSC transmits a Change Service Command message to the base station in whose coverage area the subscriber unit is located. The Change Service Command proposes a new service configuration to accommodate both the old and the new call. The base station, subscriber unit, and MSC may interchange further messages to modify the proposed service configuration if necessary. Messages are exchanged until the base station, subscriber unit, and MSC reach an agreement regarding the new service configuration. The present invention also provides support for soft handoff. The new service configuration is presented to all target base stations involved in the soft handoff, so that the subscriber unit may make use of the new service configuration while in soft handoff.
    • 一种用于在无线通信系统中提供移动交换中心(MSC)发起的服务协商的系统和方法。 如果在用户单元已经在业务信道上一个新的呼叫到达用户单元,则服务配置的改变可以允许用户单元接收新的呼叫,同时保留旧的呼叫。 MSC发起的服务协商可用于建立业务配置的变更。 MSC向用户单元所在的其覆盖区域的基站发送更改业务命令消息。 Change Service命令提出了新的服务配置,以适应旧的和新的呼叫。 如果需要,基站,订户单元和MSC可以互换另外的消息以修改所提出的服务配置。 交换消息直到基站,用户单元和MSC达成关于新业务配置的协议。 本发明还提供对软切换的支持。 新的服务配置被呈现给涉及软切换的所有目标基站,使得用户单元可以在软切换时使用新的业务配置。
