Embodiment Construction

[0016] The invention is applicable to various radio access network types. These network types include, but are not limited to, so-called third generation (3G) wireless cellular communication networks, such as those radio access networks based on the cdma2000 or W-CDMA standards. Accordingly, it should be understood that the following discussion of specific system types and implementations is for illustrative purposes only. It should also be understood that where illustrative variables are involved, such as various timers or counters, and minimum and maximum values, these values ​​may be configured according to specific implementation requirements.

[0017] Now turning to the attached image, figure 1 A wireless communication network, indicated generally with reference numeral 10, is illustrated. Network 10 includes a radio access network (RAN) 12 and a core network including a mobile switching center (MSC) 14 and associated home location register (HLR) 16 and packet data serv...

Abstract

Communication traffic associated with one or more mobile terminals is monitored to efficiently manage allocated radio resources. A rate management technique dynamically adjusts allocated radio resources to increase or decrease the data rate capacity of allocated radio channels based on actual channel usage. In this manner, radio resources are more efficiently utilized because the amount of excess capacity allocated to individual subscribers is reduced. Monitoring communication traffic may also be used to determine whether additional radio channel resources are allocated to a given subscriber. For example, in a cdma2000 radio access network, subscribers are typically allocated fundamental radio channels and then assigned supplemental channels to access higher data rate services. By monitoring fundamental channel traffic characteristics, such as the queue length or packet size of outgoing packet data, the radio access network can determine whether supplemental channel allocation is warranted.

Description

technical field [0001] The present invention relates generally to wireless communication systems, and more particularly to such systems using variable rate or variable bandwidth radio channels. Background technique [0002] As wireless communication systems have developed, the range of services provided by such systems has also expanded. The increasing variety, complexity, and quality of available services have attracted more and more people who use wireless communications in their daily lives. For example, today's mobile terminal users can subscribe to a wide range of voice and data services, including Internet access, electronic mail, and other data services in addition to more conventional voice services. It can be expected that the demand for wireless communication services will continue to grow as new services are added and existing services are improved. [0003] While the demand for data services continues to grow, the resources available to provide these services a...
