Method for selecting a route within a wireless ad-hoc routing protocol using a QoS metric. The method begins by dynamically defining a routing zone that encompasses at least two of the network nodes. A communications link is established between the source node and a destination node. If the destination node is within the routing zone of the source node, the route is determined by a proactive routing protocol. If, however, the destination node is outside the routing zone, the route is determined using a reactive routing protocol. A QoS metric for each route is calculated by combining the individual QoS metrics for each hop within the particular route. Finally, the route with the best QoS metric is selected to use as the communications link between the source node and the destination node.

The present invention is based on a concept to provide session and profile management for network communication, especially over hypertext transfer protocol (HTTP), employing available communication methods. Session and profile management is available and standardized for mobile communication by the means of the wireless session protocol (WSP) employable for wireless application protocol (WAP) communication. This wireless session protocol (WSP) is limited to mobile communication. The analog communication standard hypertext transfer protocol (HTTP) available and standardized for wireline communication does not offer a session and profile management. The present invention offers a method to establish an analog session and profile management by the means of cookies or modified uniform resource locators (URL) even over the hypertext transfer protocol (HTTP) without requiring substantial changes to the hypertext transfer protocol (HTTP) standard.

These dynamic attributes may contain information such as the wireless protocol involved, the frame type, the source type, the sequence number, the delivery timing requirements, and the delivery mode of subsequent frames.

A digital wireless telephone downloads software related to digital telephone services using a client browser. The digital telephone initiates a data call to an interworking unit via a digital wireless telephone network, using a prescribed wireless data protocol such as IS-95A. The interworking unit recovers the payload of the wireless data packets to establish a two-way data link with the digital telephone. The interworking unit sends data messages to a destination server across a second two-way data link in a packet switched network to establish a two way session between the digital telephone and the destination server. The user of the digital telephone can thus communicate with the server via a two-way application-layer session using hypertext-based messaging. The digital telephone can thus navigate between different servers on the packet switched network for activation of different digital telephone services, and for downloading new software or updating existing software related to the digital telephone services.
