    • A method and apparatus that enables incremental control the flow of downlink data on an external interface-by-interface basis, reducing the risk of repeatedly exhausting internal memory resources. A mobile device (300), having a plurality of device interfaces (328-330) for transmitting data received from a network (306) through a network controller (302), includes an identity associating layer (322) that associates identifiers with packet data protocol contexts corresponding to the plurality of device interfaces. A general resource indicator (334) generates a first indication in response to system memory of the mobile device being substantially exhausted, and a private resource indicator (336) generates a second indication in response to private resources corresponding to the plurality of device interfaces being substantially exhausted. A control processing unit (332) generates a flow control indication signal in response to the first indication, the second indication, flow control information corresponding to the plurality of interfaces, and the identifiers associated by the identity associating layer. A bit-map generator (338) generates a bit-map, based on the flow control indication signal, that is transmitted to the radio network controller, which interprets the bit-map to discretely control transmission of data from the radio network controller to the plurality of device interfaces.
    • 一种能够在外部逐个接口的基础上增加对下行链路数据流的控制的方法和装置,从而降低内部存储器资源的重复耗尽的风险。 一种具有多个设备接口(328-330)的移动设备(300),用于通过网络控制器(302)发送从网络(306)接收的数据,包括将标识符与分组数据相关联的标识关联层(322) 对应于多个设备接口的协议上下文。 一般资源指示符(334)响应于基本上耗尽的移动设备的系统存储器生成第一指示,并且专用资源指示符(336)响应于对应于多个设备接口的私有资源而生成第二指示, 累。 控制处理单元(332)响应于第一指示,第二指示,对应于多个接口的流控制信息以及由身份关联层相关联的标识符,生成流控指示信号。 位图生成器(338)基于流控制指示信号生成被发送到无线电网络控制器的位图,其解释位图以离散地控制从无线电网络控制器到第 多个设备接口。
