Patent number: 8634840Abstract: A telecommunication system comprises a radio network controller (RNC), and a Node-B (NB) for enabling wireless communication with a user terminal (UE). The RNC establishes an enhanced dedicated transport channel (E-DCH) which enables uplink data traffic with a determined maximum data rate from the user terminal (UE) to the NB. The RNC further establishes a high speed DL shared channel (HS-DSCH) which enables downlink data traffic with a determined maximum data rate from the NB to the user terminal. The NB comprises a HSDPA scheduler (HS-S) scheduling the data rate for the DL data traffic via the HS-DSCH and a EUL scheduler (EUL-S) scheduling the maximum data rate for the UL data traffic via the E-DCH. The NB exchanges data rate information between the HS-S and the EUL-S. Furthermore, the NB monitors the quotient (Q) between DL data rate and the UL data rate.Type: GrantFiled: February 12, 2008Date of Patent: January 21, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Jan Lindskog, Andreas Andersson, Pär Ankel, Anders Ranheim

Publication number: 20130107730Abstract: A method in a base station, and a base station, adapted for scheduling and receiving uplink transmissions from user entities and further forwarding data related to such transmissions to a core network, wherein the base station being adapted for transmitting serving grant signals for allowing a user entity to transmit uplink transmissions at a given maximum granted data rate, at least at a subsequent transmission opportunity. An uplink transmission from a user entity may be responded to by the base station by a not-acknowledge, NACK, or an acknowledge, ACK, signal. The method comprises the steps of: detecting the rate of an uplink transmission; detecting whether an overload situation exists, and if the rate exceeds the granted rate and an overload situation exists, sending an ACK to the user entity without forwarding any uplink data to the core network.Type: ApplicationFiled: January 27, 2012Publication date: May 2, 2013Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Par Ankel, Rikard Kaer

Patent number: 8345613Abstract: The present invention relates to a method for grant violation detection in an enhanced uplink (UL) telecommunication system. According to the method a radio network controller (RNC) establishes a first enhanced UL transport channel (E-DCH) which enables uplink data traffic with a certain data rate from a user terminal UE at least to a first base station. At least a first downlink transmission is performed to the user terminal UE including a first E-DCH. A Node B NB detects the scheduled data rate on which the user terminal UE transmits and further controls if the scheduled data rate detected is higher than the maximum data rate defined by the first E-DCH channel scheduled grant. If this is the case the Node B NB performs at least a second following downlink transmission including the first E-DCH channel scheduled grant.Type: GrantFiled: October 9, 2007Date of Patent: January 1, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Pär Ankel, Rikard Käer, Andreas Andersson
