Embodiment Construction

[0016] FIG. 1 illustrates an exemplary wireless communication network, generally indicated by reference numeral 10. As shown in FIG. The wireless communication network 10 may be any type of wireless communication network, such as a CDMA network, a WCDMA network, a GSM / GPRS network, an EDGE network or a UMTS network. In one exemplary embodiment, network 10 is based on the cdma2000, 1xEV-DV standard promulgated by the Telecommunications Industry Association (TIA), although the invention is not limited to such implementations. Here, network 10 communicatively couples one or more mobile stations 12 to another mobile station 12 or to a public switched telephone network (PSTN) 14, an integrated data services network (ISDN) 16 and / or a public data network ( PDN) 18, such as the Internet. To support this functionality, network 10 includes radio access network (RAN) 20 connected to packet core network (PCN) 22 and IS-41 network 24 .

[0017] The RAN 20 typically includes one or more ...

Abstract

A Packet Data Services Node (PDSN) optionally frames user data from an Application IP packet received from a public data network (e.g., the Internet) into a Point-to-Point Protocol (PPP) frame, and encapsulates the Application IP packet or PPP frame data into one or more Generic Routing Encapsulation (GRE) frames for further transmission within a wireless communication network. The PDSN additionally inserts into each GRE frame, Application IP packet fragmentation information that indicates whether the Application IP packet or PPP frame terminates in the associated GRE frame. Other network nodes, such as a Packet Control Facility (PCF) or Base Station Controller (BSC), may interpret the fragmentation information and ascertain the boundaries of Application IP packets or PPP frames, using this information to improve network efficiency.

Description

technical field [0001] The present invention relates generally to the field of wireless communication networks, and in particular to methods of communicating boundaries of data packets to network nodes. Background technique [0002] Third generation (3G) wireless communication networks provide mobile users with wireless access to packet data networks, such as the Internet. Many Internet applications and services that were once only available to users of fixed terminals are now available to mobile users via wireless communication networks. Services such as real-time streaming video and music, online interactive gaming, text messaging, e-mail, World Wide Web browsing, and voice over IP (VoIP) or push-to-talk ("walkie-talkie" functionality) are only now being provided to Several examples of services for mobile users. [0003] These services are characterized by packet-switched data transfers, in which data is encapsulated into logical units called packets, which contain sourc...
