摘要:
Active and inactive segmentation states are defined for transparent mode for a radio access network (RAN) interfacing with a core network (CN) and a user equipment (UE). If transparent mode is valid on the Iu-interface between the RAN and the CN, then an inactive segmentation state indicates to peer (UE/RAN) segmentation and reassembly (SAR) entities such as at the radio link control (RLC) layer that segmentation is blocked in the UTRAN, over the Uu-interface, and in the UE so that TTIs with periodicities greater than the minimum transmission interval may be utilized, except over said Iu-interface.
摘要:
A method and an arrangement are disclosed for resetting a communication connection between a first communication device and a second communication device in a cellular radio system. Firstly, there is detected the need for resetting the communication connection. There is transmitted from the first communication device to the second communication device a first piece of information indicating the need for resetting the communication connection. A resetting procedure is performed at the second communication device, and there is transmitted from the second communication device to the first communication device a second piece of information indicating the completion of the resetting procedure with respect to the second communication device. There is also inserted into a certain piece of information transmitted between the first communication device and the second communication device an indication of an effective number of certain resetting operations associated with a certain detected need for resetting the communication connection.
摘要:
Reset of one or more state variables of a User Equipment (UE) RLC layer is carried out by signaling reset from a radio link control layer of a source radio network controller (RNC) to a radio link control layer of the UE during a seamless control relocation procedure in which a possible loss of synchronization and consequent disruption in communication between the UE and a target RNC is avoided.
摘要:
A method, user terminal and network entity sets up channels in a wireless communications network by receiving a broadcast message including at least one predefined radio configuration at a user terminal. The method also includes receiving a configuration message from a network controller at the user terminal. The configuration message includes an indication to configure the user terminal to adopt the predefined radio configuration for a new transmission channel. The method also includes indicating that the user terminal is configured to transmit data to the network controller according to the predefined radio configuration.
