Patent number: 10362597Abstract: A node (100, 200) of a cellular network controls sending of first uplink grants to a communication device (10). The first uplink grants indicate first uplink radio resources allocated to the communication device (10) and are sent in response to receiving scheduling requests from the communication device (10). Further, the node (100, 200) controls sending of second uplink grants to the communication device (10). The second uplink grants indicate second uplink radio resources allocated to the communication device (10) and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device (10) and the configured periodicity of sending the second uplink grants, the node (100, 200) controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.Type: GrantFiled: August 26, 2014Date of Patent: July 23, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Eric Andersson, Ying Sun, Lotta Voigt

Patent number: 10219289Abstract: A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.Type: GrantFiled: October 1, 2013Date of Patent: February 26, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Vincent Huang, Ying Sun, Lotta Voigt, Eric Andersson, Mona Matti

Patent number: 9622171Abstract: A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.Type: GrantFiled: October 6, 2014Date of Patent: April 11, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lotta Voigt, Eric Andersson, Mathias Sintorn
