Patent CA-2435193-A1 (CA)
Inventor: SHEN GANGXIANG
IPC: H04L45/24
Filed: 2003-07-14
Abstract: This disclosure introduces a significant extension to the method of p-cycles for network protection. The main advance is the generalization of the p-cycle concept to protect multi-span segments of contiguous working flow, not only spans that lie on the cycle or directly straddle the p-cycle. This effectively extends the p-cycle technique to include path protection, or protection of any flow segment along a path, as well as the original span protecting use of p-cycles. It also gives an inherent means of transit flow protection against node loss. We present a capacity optimization model for the new scheme and compare it to prior p-cycle designs and other types of efficient mesh-survivable networks. Results show that path-segment-protecting p-cycles ("flow p-cycles" for short) have capacity efficiency near that of a path-restorable network without stub release. An immediate practical impact of the work is to suggest the of use flow p-cycles to protect transparent optical express flows through a regional network.
Patent CA-2437296-A1 (CA)
Title: Maintenance link using active/standby request channels
Inventor: ROUPHAEL ANTOINE J
IPC: H04B7/26
Filed: 2001-02-07
Abstract: Multiple field units in a CDMA system are synchronized for communication with a base station using shared forward and reverse link channels. In an illustrative embodiment, each field unit is assigned a time slot in a forward link channel to receive messages from the base station. Likewise, each field unit is assigned a time slot on a common reverse link channel for transmitting messages to the base station. Timing alignment and power level control among each of many field units and the base station is achieved by analyzing messages received at the base station in a corresponding time slot as transmitted by each field unit. Thereafter, a message is transmitted from the base station in a corresponding time slot to a particular field unit for adjusting its timing or power level so that future messages transmitted from the field unit are received in the appropriate time slot at the base station at a desired power level. In this way, minimal resources are deployed to maintain communication and precise synchronization between a base station and each of multiple users, minimizing collisions between field units transmitting in adjacent time slots on the reverse link. This method reduces the frequency a field unit must rely on the use of a slotted aloha random access channel according to IS-95.

IPC: H04W4/20
Filed: 2002-04-29
Abstract: In a system, called an application meneger, portable devices (1) can be connected in various kinds of local area networks (LANs). In the portable devices local browsers are run to find services by listening in the local area network to messages broadcast from a local information server (5) through some base unit (3).

The address information is used by a local browser to obtain, through the Internet, general information of the services from an HTTP  server (9), that contains information of applications, such as graphical information including icon files and short descriptions of the applications.  After receiving the general information symbols of available services are shown on the display of the portable device. The user can then by a single click access a service and then the local browser automatically downloads the user part of the application the symbol of which has been clicked and starts to execute the program of the application, the executing generally not requiring communication or information relevant to the current location of the user, such as timetable information for trains and air flights.
