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.

include using an application on a mobile device to establish first wireless communications with a first hazard detector that was previously paired with the user account. The method may also include transmitting, to the first hazard detector and using the first wireless protocol, a transmission that instructs the first hazard detector to establish second wireless communications with a second hazard detector, where the second wireless communications use a second wireless protocol. The method may additionally include transmitting network credentials to the first hazard detector using the first wireless protocol, where the credentials are then sent from the first hazard detector to the second hazard detector using the second wireless protocol, such that the second hazard detector can pair with the user account using the first wireless protocol.

A communication terminal initiates a Wireless Session Protocol (WSP) session by forwarding a request of data to a server. The request comprises an identification of the requested data and a communication terminal identification number provided by the server. The server. when receiving a request containing a communication terminal identification number, recalls user profile information from an associated database memory corresponding to said communication terminal identification number. The user profile information indicates a data format which will be handled by the communication terminal. Then the server replies to the request by forwarding the requested data in the format defined by the user profile information.

The network monitoring system also includes an analysis engine configured and operable to identify a list of root causes identifying failure events based on the at least one KPI rule in the at least one rule set.

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.

To address the need for an apparatus and method for transcoding among multiple wireless protocols, the present invention provides a framework for more generalized transcoding. A voice processing resource (e.g., 105) of a transcoder (101) receives the dynamic transcoding attributes (e.g., 201–207) for a frame and then transcodes that frame according to the requirements of the transcoding attributes. 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.

A system for establishing encryption keys in a manner suitable for linking low complexity and/or power constrained wireless devices. The present invention uses a combination of encryption algorithms and events, possibly including user manual intervention, to create a randomized encryption key that is substantially more difficult for a third party device to decipher than present automated algorithms currently in use. A user may randomly trigger, through a key press, information to be sent from a sending device to a receiving device which is used to establish an encryption key.

A pipelined analog to digital converter (ADC) that is arranged to dynamically adapt its resolution and sampling frequency based on at least one of a determined mode of communication, communication protocol and the strength of a received wireless signal. Since some communication protocols are communicated with a relatively low number of bits (low resolution), the ADC provides for disabling at least a portion of its pipelined stages that provide the higher resolution bits if this type of protocol is detected. By lowering the ADC's resolution and/or frequency for a standby mode communication, a considerable amount of power can be conserved. Similarly, relatively high resolution communication protocol can be processed by the ADC by enabling sufficient pipelined stages to provide a higher resolution (number of bits).
