Appl. No.:

12/966118

Inventors:

Ahmadreza Hedayat - Allen TX, US
Brian D. Hart - Sunnyvale CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04B 7/212

US Classification:

370322, 370349, 3703954, 370445

Abstract:

Techniques are provided for a multi-user reservation sequence used when transmitting a multi-user transmission in a wireless network. At a wireless access point device configured to operate in a wireless network, a multi-user request-to-send packet is transmitted as part of a multi-user reservation sequence prior to a multi-user transmission from the wireless access point device to a plurality of wireless client devices that are the intended recipients for the multi-user transmission. The multi-user request-to-send packet comprises duration information and address information configured to address at least some of the plurality of wireless client devices. Clear-to-send packets transmitted from two or more of the plurality of wireless client devices in response to the multi-user request-to-send packet are received at the wireless access point device. Each clear-to-send packet comprises identical content. In some scenarios, the multi-user request-to-send packet is preceded by a single-user request-to-send packet directed to a designated wireless client device.

International Classification:

G06F 15/16

US Classification:

709206, 709224

Abstract:

There is set forth herein a computer program product, computing device, and method for displaying an email message. In one example, a computing device receives an input comprising at least one criterion for redacting email messages; stores the at least one criterion in a configuration of a client computer program; receives an email message having a field, the field comprising a first content; determines whether a condition of at least one of the email message and a current state of the computing device satisfies the at least one criterion stored in the configuration of the client computer program; and, in response to determining that the condition satisfies the at least one criterion, displays a second content in place of the first content in a user interface of the client computer program, wherein the second content is different than the first content.

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04J 3/24

US Classification:

370312, 370474

Abstract:

Techniques are provided to enable group addressing for multicast transmissions in a frame that is configured to support multi-user transmissions. The frame comprises a header field that is configured to indicate to recipient devices associated with a multi-user transmission interval during which time, frequency and spatial channel resources are allocated to allow for the transmission of a data frame or simultaneous transmission of corresponding ones of a plurality of data frames to respective recipient devices. In the header field, group identification information is wirelessly transmitted that indicates a group of recipient devices which are to receive a transmission during the multi-user transmission interval. Data is wirelessly transmitted for a multicast transmission during the multi-user transmission interval that follows the header field, where the multicast transmission is intended for a group of recipient devices that are members of a multicast group corresponding to group identification information contained in the header field.

Appl. No.:

8/931969

Inventors:

Brian E. Hart - Dallas TX

Assignee:

Northern Telecom Limited - Montreal

International Classification:

H04M 342

US Classification:

379202

Abstract:

A switch for a telephony system in which an automatic conferencing service resides as a software module. To establish a conference call using the automatic conferencing service, an originating party dials a conference call access number. In response, the originating party receives a prompt tone indicating that phone numbers for a series of terminating parties for which participation in the conference call is desired. After entering a first phone number, the originating party selects an end of phone number delimiter. The originating party may then enter a next phone number or select an end of phone numbers entry delimiter. Upon detecting the end of phone numbers entry delimiter, the automatic conferencing service will send a call request for each of the terminating parties for which phone numbers were provided, initiate a countdown a time-out period and apply ringback to the telephone of the originating party. Upon receiving an answer from a first one of the terminating parties prior to expiration of the time-out period, ringback is discontinued and a call between the originating party and the first one of the terminating parties is completing. If additional ones of the terminating parties answer the call request before expiration of the time-out period, the additional ones of the terminating parties are bridged to the call.

US Classification:

370329, 370338

Abstract:

Dynamic bandwidth selection techniques are provided for a plurality of wireless access point devices that operate in a wireless local area network. Each access point device is capable of serving wireless client devices with a bandwidth from a set of possible bandwidths associated with one or multiple contiguous or non-contiguous radio frequency channels. A bias is generated based on determined type of traffic or client composition for each access point device, the bias favoring a channel assignment that results in a particular bandwidth in the set of bandwidths. The bias is applied to metrics representing severity and degree of interference for each channel to generate adjusted metrics. A bandwidth from the set of possible bandwidths is selected for each access point device based on the adjusted metrics.
