Appl. No.:

10/112348

Nortel Networks Limited - St. Laurent

International Classification:

H04Q 7/00

H04B 7/216

US Classification:

370331, 370335, 370342, 455437

Abstract:

An ANC is formed to “dummy fill” a neighbor list that is to be transmitted to a mobile terminal that is presently located in a border cell with neighboring BTSs for which a hand-off request cannot be granted. Accordingly, while a hand-off cannot occur to a BTS of a proximate cell that does not qualify as a neighbor because it is serviced by a different ANC in a 1xEVDO network, identifying the BTSs of the non-neighbor and proximate cells (“dummy list BTSs”) prompts the mobile terminal to request a hand-off to a dummy list BTS when the BTS provides a better pilot signal. Because the ANC can readily identify the BTS from the dummy list, it knows that a hand-off cannot be facilitated therefor. Accordingly, the ANC instructs the mobile terminal to drop the call (data packet connection). Because many wireless data packet networks utilize at least a subset of established IP protocols and are able to establish point-to-point protocol communication links (higher layer communication links), commanding a mobile terminal to drop the call is a command to drop the call at the lower layers.

International Classification:

H04B 7/216

US Classification:

370335, 455 6711

Abstract:

A wireless communications system includes access networks and access terminals. Within each cell or cell sector, reverse links and forward links are defined between an access network and multiple access terminals in the cell or cell sector. Based on a reverse data rate threshold value calculated from noise measurements, the access network indicates to access terminals within its cell or cell sector whether activity on reverse links are to be increased or decreased.

International Classification:

H04L 12/26

US Classification:

370232, 370252

Abstract:

Provided is a system and method for maximizing throughput in a telecommunications network. The method is operable to select and service a request for a communication session by selecting a bit rate and assigning the bit rate to the request. The method selects the request from a pool of queued requests and the bit rate from all supported bit rates. The request and bit rate are selected based on calculations that determine an amount of power needed for each queued request at each bit rate. The calculations result in ratios representing each combination of power and bit rate for each request. The method selects the ratio having the highest number of bit rates per power unit and assigns the bit rate to the associated request. This approach enables the method to select a queued request according to current network constraints and so provides an optimal approach that maximizes throughput.

International Classification:

US Classification:

455444, 455443, 455445, 455446, 455447

Abstract:

Overlay and underlay carriers are used to transmit traffic over a cellular network for a call associated with a mobile terminal. A method involves determining which one of the underlay carrier and the overlay carrier is to carry the traffic as a function of a resource parameter associated with a resource for transmitting the traffic and a mobility parameter of the mobile terminal. In some implementations, the method is applied at for example a base station to a plurality of calls associated with various mobile terminals within a cell and the calls are assigned to the underlay carrier and the overlay carrier using an optimization routine that optimizes a function associated with the capacity while imposing a constraint such as for example a constraint on a hand-off rate between the carriers.

International Classification:

H04J 3/16

US Classification:

370437, 370465, 370468

Abstract:

A wireless communications network includes cell segments each having at least a first type wireless link and a second, different type wireless link. Network access equipment is able to hand off mobile stations between the first type and second type wireless links to balance the loading of the wireless links. In one example implementation, the first type wireless link is a 1×EV wireless link, and the second type wireless link is a 1×RTT or other CDMA 2000 wireless link. The carriers can be co-located within a common cell segment, or located within different cell segments.

US Classification:

455453, 4554521, 4554522

Abstract:

During a wireless call, eighth rate gating is dynamically switched off per sector for either all calls in the sector of the base station or per mobile station when a pre-determined forward link loading threshold is exceeded in that sector, and dynamically switched on eighth rate gating for either per mobile station or for all calls in the sector of the base station when the forward link loading in that sector drops below a predetermined forward link threshold.

International Classification:

H04W 4/00

US Classification:

370331

Abstract:

A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

International Classification:

H04W 72/00

US Classification:

4554522, 370328

Abstract:

The invention provides for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.
