Patent number: 8185143Abstract: Systems and methods for selectively replaying voice data. Voice data received in a communication session is both buffered by a server such that the buffered data can be played by a recipient device.

Accordingly, in the wireless Internet communication method of the mobile communication terminal, a W-LAN function is set in the same manner as that in which a CDMA data call is set through modification of the SVD scheme, so that a W-LAN data protocol such as the DHCP (which can be used when the W-LAN function is set) and a voice call service can be provided at the same time.Type: GrantFiled: October 26, 2005Date of Patent: March 20, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Chang-Ki Jeong, Jeon-Man Park

Patent number: 8126504Abstract: A method of controlling a wireless communication system including a plurality of communication devices is disclosed. In the method, firstly, one of the communication devices establishes a fixed beam pattern and transmits a training signal, and another communication device receives the training signal while scanning a beam direction by changing the AWVs of an antenna array. Next, it obtains a data string describing a relation between an incoming direction and a received-signal characteristic at the other communication device based on a reception result of the training signal. Then, it obtains first AWVs with which a beam is formed in a plurality of incoming directions of the received signal based on the data string. The roles of these two communication devices are interchanged and similar processes are performed in order to obtain second AWVs, and then one of AWV combinations combining first and second AWVs are used for wireless communication between these communication devices.Type: GrantFiled: August 7, 2009Date of Patent: February 28, 2012Assignee: NEC CorporationInventors: Kenichi Hosoya, Kenichi Maruhashi, Naoyuki Orihashi

Patent number: 8126503Abstract: A system and method for providing dynamic allocation of MIMO communication resources during a single communication. Various aspects of the present invention may comprise determining a first set of MIMO communication resources to utilize for communicating a first portion of a unit of information. The first set of MIMO communication resources may be allocated for communicating the first portion of the unit of information. A second set of MIMO communication resources may be determined to utilize for communicating a second portion of the unit of information, where the second set of MIMO communication resources is different from the first set of MIMO communication resources. The second set of MIMO communication resources may be allocated for communicating the second portion of the unit of information. The first and second portions of the unit of information may, for example, be communicated consecutively or concurrently.Type: GrantFiled: July 21, 2009Date of Patent: February 28, 2012Assignee: Broadcom CorporationInventors: Jeyhan Karaoguz, Nambirajan Seshadri, James D.

Patent number: 8121638Abstract: A mobile device and a method for providing security to a mobile device having two or more communication domains is provided. The mobile device receives a communication service request. The communication domain of the communication service request is determined, the request domain being one of the two or more communication domains of the mobile device. A set of applicable restrictions is then determined from a list of communication restrictions comprising restrictions on use of services of the mobile device for each of the two or more communications domains. These applicable restrictions are then applied to the communication service request by the mobile device.Type: GrantFiled: February 27, 2009Date of Patent: February 21, 2012Assignees: Research In Motion Limited, Ascendent Telecommunications, Inc.Inventors: Douglas Gisby, Colin Werner, Michael Gray, Shen-Yuan (Michael) Yap

Publication number: 20120040715Abstract: A coexistence interference mitigation method is provided. In a wireless network, a wireless device is equipped with multiple radios in the same device platform. The wireless device also has a control entity that communicates with the multiple co-located radio modules. A first radio module receives a notification from the control entity. The notification informs a critical signaling status of a second radio module co-located with the first radio module. Upon receiving the notification, the first radio module stops uplink transmission due to coexistence interference and transmits a coexistence indicator to its serving eNB. After a certain period, the first radio module receives a second notification that informs a completion status of the critical signaling of the second radio module. Upon receiving the second notification, the first radio module resumes uplink transmission and transmits a coexistence resume indicator to the eNB.Type: ApplicationFiled: August 11, 2011Publication date: February 16, 2012Inventors: I-Kang Fu, Willaim Plumb
