20140133454 | SELECTIVE ROBUST HEADER COMPRESSION (RoHC) FOR A VoIP CALL IN A CELLULAR COMMUNICATIONS NETWORK - Systems and methods for selectively enabling Robust Header Compression (RoHC) for Voice over Internet Protocol (VoIP) calls in a cellular communications network are disclosed. In one embodiment, a data radio bearer for a VoIP call is established between a base station and a mobile terminal. During the VoIP call, a radio frequency parameter for the data radio bearer is monitored. When the radio frequency parameter for the data radio bearer satisfies a predefined coverage-based condition, the base station enables RoHC for the VoIP call. In one preferred embodiment, the radio frequency parameter is a Signal-to-Interference-plus-Noise Ratio (SINR) for the data radio bearer for the VoIP call, and the predefined coverage-based condition is a predefined SINR threshold below which the base station enables RoHC. By enabling RoHC in this manner, RoHC resources are selectively made available for those VoIP calls that will benefit most from increased cell coverage provided by RoHC. | 05-15-2014 |

20140341194 | METHOD AND ARRANGEMENT FOR CONTROLLING TRANSMISSION OF DELAY SENSITIVE DATA IN A PACKET DATA COMMUNICATION NETWORK - This disclosure deals with an apparatus in a base station for controlling transmission of delay-sensitive data from a transmitter over a transmission link in a packet data communication network, which transmitter is capable of changing between a TTI bundling enabled mode and a TTI bundling disabled mode. The apparatus comprises: a receiver for receiving data from the transmitter over the transmission link; a decision unit for deciding that the transmitter should change TTI bundling mode; a silent mode detection unit for detecting that the transmitter is in the silent mode; and a triggering unit for triggering change of TTI bundling mode in response to deciding that the transmitter should change TTI bundling mode and in response to detecting that the transmitter is in the silent mode. The disclosure further relates to a corresponding method. | 11-20-2014 |
