摘要： Disclosed are techniques for performing an antivirus task in a mobile wireless device running an embedded operating system. In one embodiment, calls intended for an application programming interface (API) function code is redirected to an antivirus function code (302). The redirection to the antivirus function code may be performed by modifying a kernel structure (203A) to point to a modified entry list instead of an API entry list (301). The redirection to the antivirus function code may also be performed by modifying the API function code to allow the antivirus function code to execute before the API function code. The kernel structure or the API function code may be properly restored back to its original form. Software implementations of these techniques may be readily loaded and unloaded, and may not require re-installation of the embedded operating system.

摘要： A method for reducing congestion in a wireless communication network is presented. The method includes monitoring a congestion level of at least one network node of the network. When the congestion level is greater than a first threshold, the method includes initiating a first congestion control mechanism. When the congestion level is greater than a second threshold, the method includes initiating a second congestion control mechanism, the second threshold being greater than the first threshold. In some implementations, the first congestion control mechanism includes codec rate adaptation (CRA), and the second congestion control mechanism includes at least one of rejecting new service requests and dropping existing services. The method may include, after initiating the first congestion control mechanism, starting a timer and, when the timer reaches a pre-determined value and the congestion level is greater than the first threshold, initiating the second control mechanism.

摘要： A method, apparatus, and computer program product for indicating and responding to various congestion levels in a communication system, such as a wireless communication network. A congestion level in the network is determined, and a percentage of data packets to be transmitted to an endpoint, such as user equipment or another network endpoint serving the user, are marked to indicate the congestion level. The endpoint determines the congestion level at the network from the percentage of received data packets that are marked and may initiate an appropriate response behavior in response to the determined congestion level.

摘要： A method is disclosed that includes sending (304) a first full header from a source compressor (106) to a destination decompressor (112) wherein the source compressor and the destination decompressor are a part of a symmetrical configuration. An IP packet including the full header is compressed into a first compressed header (310) based on the context established in the first full header. The first compressed header is sent (312) from the source compressor to the destination decompressor. The compressor receives (322) a second full header from the destination compressor wherein the second full header indicates that the destination decompressor did not receive the first full header. The second full header can include a modified field or has an incremented generation identification. The source compressor sends (336) another full header to the destination decompressor.

摘要： A method, apparatus, and computer program product for responding to congestion levels in a communication system by rate adaptation. A congestion condition is indicated by marking data packets. In response to receiving an indication of congestion, a data rate is reduced. A rate reduction inhibit timer is started, and further rate reduction is initiated if congestion is indicated after the rate reduction inhibit timer has expired. A rate increase timer is used to initiate a rate increase if no indication of congestion is received during a rate increase time.
