Patent number: 7983203Abstract: A system and method for including aggregation control information in an aggregate frame that facilitates enhanced power efficiency is provided. Aggregation control information may include lengths of frames addressed to different stations and/or transmission opportunities to different stations. A receiving station is then able to calculate an offset within the aggregate frame that identifies the position of frames addressed to the receiving station and/or offset when it can use the medium to transmit it's data. The receiving station may then enter a sleep mode and awaken at a proper time for using the medium to either receive, or transmit data on the medium. Additionally, aggregation control information may include rate information to facilitate aggregation of multi-rate data in an aggregate frame.Type: GrantFiled: May 3, 2005Date of Patent: July 19, 2011Assignee: Nokia CorporationInventors: Naveen Kumar Kakani, Yousuf Saifullah, Nico VanWaes, Srinivas Sreemanthula, Khiem Le

Patent number: 7953799Abstract: The invention relates to a service control device and method for controlling service execution in a communication network. A service script for a user is loaded in response to the receipt of an incoming message, and it is checked based on a comparison of the loaded service script and the incoming message whether a service is to be triggered. If a service triggering has been determined, a service is activated in an external service execution environment. Due to the fact that the service execution is not performed in the service control point but in an external service execution environment, the service logic does not have to be provided at the service control point. It provides a flexible way to define, execute, and control user-specific, operator, and third party services combining various service capabilities.Type: GrantFiled: February 23, 2001Date of Patent: May 31, 2011Assignee: Nokia Siemens Networks OyInventors: Basavaraj Patil, Khiem Le, Stefano Faccin, Curt Wong, Srinivas Sreemanthula, Kengatharan Sivalingam

Patent number: 7307955Abstract: A “loose ACK” method by which a radio access network of a cellular network monitors wireless transmission of packets according to a layered protocol including a radio layer (near the physical layer) and an upper layer, the method including: a step (23) of slow release—in what is called normal buffer management—in which the upper layer removes from a buffer maintained by the upper layer the oldest packet in the buffer when the buffer is full and a new packet arrives, and does so independently of whether the packet being removed has been acknowledged by the radio layer of the terminal; and a step (24) of local acknowledgement in which the radio layer sends an acknowledgement to the upper layer on the occurrence of a predetermined event. The local acknowledgement can trigger either special mode buffer management or release of the buffer to a target (entity or layer).Type: GrantFiled: December 31, 2003Date of Patent: December 11, 2007Assignee: Nokia CorporationInventors: Rene Purnadi, Srinivas Sreemanthula, Haihong Zheng, Khiem Le

Patent number: 7263067Abstract: A method and equipment for accelerating throughput of communication segments from a sender (30) to a receiver (40) each of which include a protocol layer (30a 40a) for providing such segments, the method in case of TCP including a first step (20a) in which the sender protocol layer (30a) initializes a congestion window (cwnd) to some initial size (iwnd) and increases the congestion window by one segment each time it receives an ACK, but upon receiving an indication of low congestion, performs a step (20c) of accelerated start in which it sets a slow start threshold (SSTHRES) to a standard initial value (typically 65535) and re-initializes cwnd to a new value, and the sender protocol layer (30a) then increments cwnd at one or another predetermined rate—depending on whether the start immediately follows a new connection or instead follows a transfer of an existing connection to a new path—in respect to received ACKs.Type: GrantFiled: July 15, 2003Date of Patent: August 28, 2007Assignee: Nokia Siemans Networks OyInventors: Srinivas Sreemanthula, Yogesh Swami, Khiem Le
