摘要： A method for simulating different MTTR settings includes determining a simulated MTTR setting and providing a simulated checkpoint queue. The simulated checkpoint queue is associated with the simulated MTTR setting and is an ordered list of one or more elements. Each element represents a buffer, and the ordered list has a head and a tail. The method also includes providing a simulated write counter associated with the simulated MTTR setting. The method further includes, in response to detecting a change to a first buffer, checking if the first buffer is represented in the simulated checkpoint queue. If the first buffer is not represented in the simulated checkpoint queue, an element that represents the first buffer is linked to the tail of the simulated checkpoint queue. An MTTR advisory system includes a memory, one or more processors coupled to the memory, a simulated MTTR setting, a simulated checkpoint queue, and a simulated write counter. The simulated MTTR setting is maintained in the memory. The simulated checkpoint queue is maintained in the memory and associated with the simulated MTTR setting. The simulated write counter is also maintained in the memory, and is associated with the simulated MTTR setting. The simulated write counter provides a count of the number of times an element is removed from the simulated checkpoint queue, wherein the element is removed from the simulated checkpoint queue in response to a write out of a buffer from volatile memory and storing in nonvolatile memory.

摘要： In the method provided, test transmissions between the mobile user terminal and base station antennas are made, and the received test transmissions processed to determine respective signal path quality for each of the base station antennas. Upon the determined signal path quality exceeding a first predetermined threshold, but being less than a second predetermined threshold higher than the first predetermined threshold, the mobile user terminal is connected to the corresponding base station antenna by control channels but not data channels so as to be time synchronised. Upon the determined signal path quality exceeding the second predetermined threshold, the mobile user terminal is connected to the corresponding base station antenna by both control channels and data channels so as to be call connected.

The method includes providing a set of information channels in the RLC layer for connection to the buffer and a set of transport channels in the MAC layer for transmission of the data units, selecting a subset of the information channels and a subset of the transport channels for interconnection, and selecting for each transport channel one or more information channels to be multiplexed on the transport channel. A mapping table and a transport block combination table are created as a result of prioritizing the selected transport channels according to a predetermined scheme in dependence on the characteristics of the information channels and then there from, determining the number of data units which may be transmitted in a timing interval.

摘要： A cellular mobile telephone network is disclosed in which a mobile station requests service in data modulated on a common random access channel (RACH) in a format associated with first a cell in which the mobile station is located. Base stations in cells neighbouring the first cell, are configured to demodulate the RACH message burst having the format associated with the first cell, and to pass the demodulated data to a radio network controller (RNC). This enables the average power required for a successful RACH transmission to be reduced.
