The present invention provides for a Domain Name Router (DNR) that uses domain names to route data sent to a destination on a network (e.g., a stub network). Each corporate entity or stub network can be assigned one or a small number of global addresses. Each of the hosts on the stub network can be assigned a global address. When a source entity sends data to a destination entity with a local address, the data is sent to the DNR using a global address. The source entity embeds the destination's domain name and its own domain name inside the data. The DNR extracts the destination's domain name from the data, translates that domain name to a local address and sends the data to the destination.

An admission control and load balancing system controls admission of packet streams or calls to a network and balances the packet traffic across the network, improving quality of service. The system includes a central database which stores information including cost data associated with individual paths and links across the network. A processor, in communication with the database, coordinates the admission control and load balancing decisions, and updates of the database cost data to reflect the dynamic network conditions, based on input from appropriate data sources. In one embodiment, referred to as the exact algorithm, the database is consulted by the admission control points or gatekeepers prior to admitting each arriving packet stream, and the database contents are updated call-by-call to reflect the allocation of resources to each admitted stream. In another embodiment, referred to as the inexact algorithm, control decision as well as database updates occur on a periodic rather than on a call-by-call basis to promote better scalability. In this embodiment, the processor periodically calculates admission decisions based on cost data in the central database. These admission decisions are then periodically forwarded to a satellite database associated with each gatekeeper, for storage and use in admission decisions until the next update epoch.

A novel and useful autonomous connectivity mechanism for use in user equipment (UE) connectivity in one or more cellular communications systems. The handover process is optimized by improving the selection of target base stations and optimizing the discontinuity period from the time of disconnection from a serving base station and connection to a target base station. The mechanism facilitates multiple cell connectivity in a network unaware manner while preserving single endpoint connectivity. The UE does not need to negotiate for or receive pre-allocated opportunities from the network for making neighboring base stations measurements. Measurement opportunities are created by the UE autonomously in accordance with UE activity patterns. Measurement opportunities are used to measure and maintain a candidate target base station list over the same or a plurality of access technologies. The parameter set tracked includes parameters that can be measured without any assistance from the target base station and which can effect the handover process, e.g., link quality, etc.

A radio access network (RNC) assigns for a real-time media session a real-time access bearer that can be shifted between a dedicated channel state and a common channel state. The assignment is made in response to receiving an access bearer assignment message indicating that the real-time media session requires a real-time access bearer of that type. The media activity of the real-time access bearer is then monitored, and the access bearer shifts to the common channel state upon detecting media inactivity during the dedicated channel state, and shifts to the dedicated channel state upon detecting media activity during the common channel state.
