摘要： Methods and apparatus are described for improving the transmission of multimedia data over wireless communication channels. These techniques include determining a physical layer packet size of the wireless communication system and determining a maximum size of a compressed header. Then, partitioning an information unit, wherein the size of the partitions are selected such that after a partition is encoded the aggregate size of the encoded partition and the compressed header are the size of the physical layer packet, or less. The techniques can be used for various types of information units, such as multimedia data, variable bit rate data streams, video streams, video teleconference stream, or voice over IP. The techniques can also be used with various over the air interfaces, such as, Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), or standards based on CDMA such as TIA/EIA-95-B (IS-95), TIA/EIA-98-C (IS-98), IS2000, HRDP, cdma2000, Wideband CDMA (WCDMA), and others.

摘要： Systems and methodologies are described that effectuate establishment of an IPSec tunnel for utilization in a wireless communication environment. IPSec establishment procedures on home base stations can be used to establish IPSec tunnels between home base stations situated on open access sectors of wireless communication environments and packet data interworking function components positioned at the contiguity of secured segments of the wireless communication environments. Moreover, high rate packet data point-to-point protocol challenge-handshake authentication protocols can be directed through the IPSec tunnels to facilitate authentication of access terminals associated with the home base stations in order to facilitate further communications with components dispersed within secure areas of wireless communication environments. Further, international mobile subscriber identities (IMSI) affiliated with access terminals associated with home base stations can be used to identify packet data serving nodes with which to establish communications between home base stations and packet data serving nodes.

摘要： A method and apparatus for reducing transmission delay in a wireless communication system that carries packetized voice and data information. Interruptions in the traffic channels cause loss of synchronization between a header compressor and a header decompressor. Rather than transmitting resynchronization information on the traffic channel, the information dropped by an interruption is re-transmitted on a non-traffic channel in parallel with the traffic channel. At the remote station, information from the traffic channel and the non-traffic channel is reassembled before input into the decompressor. Alternatively, the non-traffic channel can be used to carry overflow information so that a higher average data rate can be achieved than the average data rate of the traffic channel alone.

摘要： Efficient transmission of cryptographic information in secure real time protocol. A transmitting terminal may be used to encrypt data with a session key derived from a bit-stream. The bit-stream may be sent with header information to the receiving terminal. To conserve bandwidth, the information may be divided into portions, and each portion transmitted with an encrypted data packet. The receiving terminal may be used to recover the bit-stream from the information portions in the packet headers, and use the bit-stream to derive the session key. The session key may be used to decrypt the data.

摘要： Systems and methods for determining the home network carrier associated with a mobile station and authorizing the provision of services to the mobile station using centralized storage of mobile station and home network information. In one embodiment, when a roaming mobile station attempts to access services, identifying information for the mobile station is used by a local server to query a centralized DNS server that stores a mapping of mobile station identifying information to corresponding home networks. The centralized DNS server returns an identification of the home network of the roaming mobile user, and the home network then determines whether to grant or deny the mobile station access to the local network. The mobile station identifying information may comprise an MSID such as an MIN, IRM or IMSI, which may serve as part of the address for the query to the centralized DNS server.

摘要： The packets generated by each of multiple packet data applications are provided to a single Point-to-Point Protocol (PPP) stack and a single High-level Data Link Control (HDLC) framing layer to convert data packets into byte streams suitable for transmission through Radio Link Protocol (RLP) connections. Each of the resultant multiple byte streams is then provided to one of multiple RLP connections having different retransmission and delay properties. The RLP connection selected for sending data from each application is based on the grade of service most appropriate for the application. At the receiver, the data from the multiple RLP connections is provided to a single PPP stack.

摘要： A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).
摘要翻译：一种用于从分组数据业务网络请求PPP实例的方法和装置，包括：移动台，被配置为向离开另一个PDSN附近的分组数据业务节点（PDSN）发送发起消息。该消息通知新的PDSN移动站的新位置，并指示与移动站相关联的休眠PPP实例的数量和每个这样的PPP实例的服务参考标识。消息内的标志可以用于指示PPP实例是否处于休眠状态（即移动台是否进行呼叫）。
