摘要： A method and apparatus for requesting Point-to-Point Protocol (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). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

摘要： A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations in order to determine whether multiple RAN-PDSN (R-P) connections are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.
摘要翻译：公开了一种新颖的方法和装置，用于在使用不同类型的无线接口的无线电接入网络（RAN）之间执行移动台（MS）的无缝切换。所描述的实施例使得MS能够在不引起路由模糊性的情况下在不同RAN之间进行切换，并且不会显着损失网络数据。使用第二无线接口，使用第一无线接口从第一RAN的覆盖区域移动到第二RAN的覆盖区域时，MS确定是否可以由RAN的改变导致路由模糊性，并且基于该确定触发重新注册其网络地址。分组数据服务节点（PDSN）内的外部代理（FA）监视网络地址重新注册，以便确定是否为相同的MS创建多个RAN-PDSN（R-P）连接。基于该确定，PDSN终止由不同RAN之间的MS的移动导致的冗余R-P网络连接。

摘要： The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted.
