US 8195187 B2Abstract
In a radio access network, multiple radio network controllers are connected to several radio nodes using a network. The interconnected radio network controllers and radio nodes are addressable, and, therefore, each radio network controller can communicate directly with each radio node and visa versa. The radio access network can be configured to avoid active handoffs between radio network controllers by maintaining a traffic channel set up between an access terminal and a radio network controller even as the flow.
This application is a continuation-in-part application of U.S. application Ser. Nos. 09/891,103, filed on Jun. 25, 2001, and 10/848,597, filed May 18, 2004 now U.S. Pat. No. 7,170,871, both of which are incorporated herein by reference.
This description relates to radio network control.
High Data Rate (HDR) is an emerging mobile wireless access technology that enables personal broadband Internet services to be accessed anywhere, anytime (see P. Bender, et al., �CDMA/HDR: A Bandwidth-Efficient High-Speed Wireless Data Service for Nomadic Users�, IEEE Communications Magazine, July 2000, and 3GPP2, �Draft Baseline Text for 1�EV-DO,� Aug. 21, 2000). Developed by Qualcomm, HDR is an air interface optimized for IP packet data services that can deliver a shared forward link transmission rate of up to 2.46 Mbit/s per sector using only (1�) 1.25 MHz of spectrum. Compatible with CDMA2000 radio access (TIA/EIA/IS-2001, �Interoperability Specification (IOS) for CDMA2000 Network Access Interfaces,� May 2000) and wireless IP network interfaces (TIA/EIA/TSB-115, �Wireless IP Architecture Based on IETF Protocols,� Jun. 6, 2000, and TIA/EIA/IS-835, �Wireless IP Network Standard,� 3rd Generation Partnership Project 2 (3GPP2), Version 1.0, Jul. 14, 2000), HDR networks can be built entirely on EP technologies, all the way from the mobile Access Terminal (AT) to the global Internet, thus taking full advantage of the scalability, redundancy and low-cost of IP networks.
In one aspect, the invention features a method for exchanging digital information using mobile access terminals in a wireless network. The method includes transmitting packets over a first traffic channel, established between a first mobile access terminal and a first radio network controller, via a first radio node without passing through a second radio network controller, and transmitting packets over a second traffic channel, established between a second mobile access terminal and the second radio network controller, via a second radio node without passing through the first radio network controller. The method also maintains the first traffic channel between the first access terminal and the first radio network controller when packets are received from or transmitted to the first access terminal via the second radio node. The method also includes transmitting packets received from the first access terminal to an external network (e.g., the Internet).
In a radio access network (RAN) multiple radio network controllers (RNCs) act as a pool of resources that collectively serve multiple radio nodes. For example, RNCs and RNs in a RAN can be linked using an Internet Protocol-based network, which allows RNs to address different RNCs within the RAN and visa versa. Load balancing mechanisms within the RAN to balance load among RNCs within the RAN as well as among server cards within a single RNC can be used. By pooling RNCs within a RAN, costly handoffs between RNCs as an access terminal (AT) moves across the RAN can be reduced, and, in some cases eliminated. The following disclosure describes several implementations of IP-based radio access networks in which RNCs are clustered together to form a pool of resources serving multiple radio nodes within a RAN.
