A monitoring system includes a central gateway. The central gateway is configured to interface the monitoring system to a WAN. The monitoring system also includes a network of radio telemetry devices. Each radio telemetry device includes a monitoring device, a radio module configured to communicate with other radio telemetry devices and the central gateway, and a processor. The radio telemetry device can be configured to acquire monitoring data and forward it to the central gateway. The radio telemetry device can also be configured to relay monitoring data from other radio telemetry devices to the central gateway allowing for the use of short range, low power radio modules.

A method and apparatus for a unique digital signature is provided. According to one aspect of the invention, a unique digital signature comprises an adapted digital signature and a service id. The adapted digital signature provides temporary or restricted privileges for a particular electronic service. In one embodiment, the electronic service is electronic message forwarding. In another embodiment, the electronic service is electronic media delivery. An authentication log file is maintained for recording status information concerning unique digital signatures.

Unique digital signature

A method and apparatus for an authenticated electronic userid comprising an adapted digital signature is provided. According to an aspect of the present invention, the adapted digital signature is generated using a secure hash function and an adaptation algorithm. According to one embodiment, a method for creating an adapted digital signature comprises retrieving an originator key, said originator key corresponding to a local userid; running a digital signature engine to create a digital signature, said digital signature based on at least said originator key and remote user information; retrieving a word from a word list, said word corresponding to at least a portion of said digital signature; and returning at least said word as said adapted digital signature.

A packet-based wireless local loop includes a wireless router operable to communicate with a network and a fixed wireless unit operable to communicate with the router over a wireless interface. The fixed wireless unit is operable to transmit a first plurality of packet messages to the router. The first plurality of messages contains analog traffic and data traffic from at least one wired device. The fixed wireless unit is also operable to receive a second plurality of messages from the router. The second plurality of messages contains analog traffic and data traffic, and the fixed wireless unit is further operable to communicate the analog traffic and the data traffic in the second plurality of messages to at least one of the wired devices.

Packet-based wireless local loop and method

A system and method including a flexible paging protocol which adjusts the allocation of resources for paging in response to the amount of actual paging traffic, by increasing resources for paging when paging traffic is heavy and decreasing them when paging traffic is light. A base station transmits a paging packet message over a paging broadcast channel containing a set of paging messages and a next page pointer. The next page pointer identifies when the next set of paging packet message will be transmitted. A user station monitoring the paging channel receives the next page pointer, and, if not being paged, goes to sleep until the next paging packet message is due. When paging traffic is light, paging messages are sent infrequently, freeing up base station resources and allowing the user station to remain asleep longer. When paging traffic is heavy, paging messages are sent more frequently, ensuring rapid response to the pages and reducing the probability of a missed call. The protocol is particularly well suited for use in TDMA environments. The next page pointer may be used in conjunction with a system which also employs a next slot pointer for increasing the speed of control traffic transactions. In a wireless packet-oriented communication system, the base station receives data packets over a backhaul connection, transmits a paging message to the mobile end system, divides the data packet into a sequence of message frames, and transmits the message frames to the mobile end system in assigned time slots.

Flexible paging for packet data

A method and apparatus for an authenticated electronic userid is provided. According to one embodiment, an adapted digital signature is generated for an outbound message from a local user that authorizes a remote user to reply to the message. The adapted digital signature becomes part of an authenticated electronic userid and, when a reply from the remote user is made, the reply message includes the authenticated electronic userid. A one-way hash function is employed to generate the adapted digital signature. According to one embodiment, if an inbound message to a local user from a remote user does not have an authenticated electronic userid, in particular the adapted digital signature, then the inbound message is rejected. An advantage of the method and apparatus described herein is that unsolicited bulk electronic messages and other non-authorized communications to a local user of an electronic message system are reduced.

Apparatus and method for an authenticated electronic userid

A method of transmission error control includes transmitting at least one frame of packet data to a receiving entity during each of a plurality of time frames, and receiving a plurality of responsive messages from the receiving entity. Each of the responsive messages identifies frames of data successfully received during a current time frame and during prior time frames. The method also includes retransmitting each of the frames of data that the responsive message does not indicate as successfully received.

Efficient error control for wireless packet transmissions

A method for establishing wireless communication comprising transmitting a request signal indicative of a request to establish communication with an external device external to a wireless communication device; determining at the wireless communication device based upon the request signal whether the external device communicates using a packet transmission protocol or a circuit switched transmission protocol; and if said external device communicates using a packet transmission protocol, transmitting subsequent communications from the wireless communication device directed to the external device using the packet transmission protocol.

Wireless packet data communication apparatus and method

A method for transmission continuation control includes establishing a physical transmission link between a first entity and a second entity, and transmitting a first user message from one of the first and second entities to the other of the first and second entities. The method also includes executing a continuation protocol between the first entity and the second entity while maintaining the physical transmission link. The method further includes transmitting a second user message from one of the first and second entities to the other of the first and second entities, and terminating the physical transmission link between the first entity and the second entity after the transmission of the second user message.

Continuation control for wireless packet data

Methods and apparatus for queuing subscriber-originated connection requests for respective calls at a server system. A server system in a telecommunications network receives subscriber-originated connection requests for subscriber pending call access to the server system, and thus, the network. Subscriber-originated connection requests are queued at the receiving server system. The server system receiving the subscriber-originated connection request transmits a first message to the respective subscriber originating the connection request upon the server system's queuing of the connection request. Subsequently, upon the server system allocating a connection resource to a queued subscriber-originated connection request, the server system transmits a second message to the respective subscriber.
