    • A system and method manages Radio Access Network (RAN) resources to service packet data transmissions at Service Quality Levels (SQL) commensurate with packet data network SQLs. A Packet Data Serving Node (PDSN) receives a data packet from a coupled packet data network. The data packet is directed toward a Mobile Station (MS) serviced by the RAN and includes a packet SQL indicator that indicates the level of service provided by the data packet network. A corresponding set of RAN resources is allocated to meet the packet SQL indicator. If the set of RAN resources cannot be allocated, the data packet SQL indicator is remarked accordingly. In another operation, the BSC receives a data packet from a MS serviced by the RAN. The data packet is intended for a coupled packet data network and includes a packet SQL indicator. The BSC first determines a set of allocated RAN resources that are servicing the transmission of the data packet to the packet data network. The BSC then maps the allocated set of RAN resources to a RAN service quality level indicator. If the data packet SQL indicator is incorrectly marked, it is remarked by the PDSN. These operation provide support for both specific SQL operations and differential SQL operations.
    • 一种系统和方法管理无线电接入网络(RAN)资源,以在与分组数据网络SQL相称的服务质量等级(SQL)下服务分组数据传输。 分组数据服务节点(PDSN)从耦合分组数据网络接收数据分组。 数据分组指向由RAN服务的移动台(MS),并且包括指示由数据分组网络提供的服务等级的分组SQL指示符。 分配相应的一组RAN资源来满足分组SQL指标。 如果无法分配RAN资源集,则相应地记录数据包SQL指标。 在另一操作中,BSC从由RAN服务的MS接收数据分组。 该数据分组旨在用于耦合分组数据网络并且包括分组SQL指示符。 BSC首先确定正在为分组数据网络传输数据分组的一组分配的RAN资源。 然后,BSC将所分配的RAN资源集合映射到RAN服务质量等级指示符。 如果数据包SQL指示符标记不正确,则表示PDSN。 这些操作为特定的SQL操作和差异SQL操作提供支持。
