摘要:
A method and system for providing a closed route for travel features a database having geographic information and input information including a starting point and a desired route length. The geographic information from the database and the input information are processed to define an outbound path from the starting point to a turning point, the turning point determined based on the desired route length, and to define an inbound path from the turning point to the starting point, the outbound path and the inbound path together defining the closed route. A representation of the closed route may be output as a static map, interactive map or a turn-by-turn listing.

In a wireless communication system (100) having a plurality of communication cells (115, 117), and a plurality of mobile stations (118) operating within selected ones of the multiple communication cells (115, 117), a method and an apparatus for selecting those communication cells (115, 117). Within each communication cell (115, 117), a base station (112) transmits a message directed to the mobile stations (118), and detects a response indicator in the selected ones of the plurality of communication cells (115, 117). The message may be a broadcast page message transmitted by the base station (112). The response indicator may be an impulse radio-frequency energy transmission generated by the plurality of mobile stations (118) operating within the selected ones of the plurality of communication cells (115, 117). The base station (112) may detect the impulse radio-frequency energy transmission on a control channel or during a predetermined time window period (303, 410, 413, 416) following transmission of the message. The base station (112) directs call traffic to the plurality of mobile stations (118) in the selected ones of the plurality of communication cells (115, 117).
摘要:
A method and apparatus is provided to update information within a first network (103) via a second network (102) when communication no longer exists with the first network. During operation the first network is accessed via a PSTN (108) message that is never answered by the first network. Based on the called number and caller-identification information, the first network updates its system information.

A wireless network device that assigns priorities to communications in a network has a first circuit for receiving wireless messages from remote wireless network devices and a second circuit operable to send wireless messages to the remote wireless network devices. A third circuit makes a determination of the relative priorities of the remote wireless network devices. The wireless network device is operable to form a message to the remote wireless network devices, where the message is used to set a backoff time in the remote wireless network devices. The backoff time sent to the remote wireless network device is related to the relative priority of the remote wireless network device.
摘要:
A system for wirelessly transmitting time constant data under a wireless protocol is contemplated. A access point device initiates a reservation of time under a protocol. The transmitting device then downloads the time constant data to the remote devices. This can take place as individual transmissions or a single unicast transmission of one block containing all the data for the remote wireless device(s). The access point polls each remote wireless device for constant time data to be sent to the remainder of the network. At the conclusion, the access point gives up the reservation so as to enable the remote wireless devices to use the access point for other forms of data traffic.
摘要:
A method of reducing tunneling in a wireless packet network. The method includes defining a home access point for a client station, determining that the client station is being serviced by an access point different from the home access point, deciding if the client station should change its home access point to the access point from which the client station receives service and initiating a change of the home access point of the client station, if so decided.
