摘要： A first session is established for a first mobile access terminal on a first radio network controller via a first radio node. A first traffic channel is established between the first mobile access terminal and the first radio network controller. A first plurality of packets are sent and received over the first traffic channel. The first plurality of packets travel between a first radio node and the first radio network controller without passing through a second radio network controller. The first traffic channel is maintained as the first access terminal moves from a coverage area of the first radio node to a coverage area of a second radio node. A second plurality of packets travel between the second radio node and the first radio network controller without passing through another radio network controller.

摘要： An optical network has an optical splitter connected to (1) a working optical subscriber unit (OSU) of a working circuit via a working optical fiber, (2) a protection OSU of a protection circuit via a protection optical fiber, and (3) one or more optical network terminals (ONTs). The present invention enables fast protection switching from the working OSU to the protection OSU. In one embodiment, the arrival times of corresponding upstream ranging reply PLOAM cells are measured at both the working and protection OSUs during ranging operations of the working OSU. In another embodiment, a cell delineation procedure is initiated at the protection OSU during normal, non-ranging operations of the working OSU to enable the protection OSU to correctly delineate upstream cells and the arrival times of corresponding upstream cells are then measured at both the working and protection OSUs. In either case, a propagation delay value is generated based on the measured arrival times for use by the protection OSU for communications with the one or more ONTs if and when protection switching is implemented upon detection of a failure in the working circuit, possibly without requiring the protection OSU to perform any ranging for the one or more ONTs.

摘要： An optical network has an optical splitter connected to (1) a working optical subscriber unit (OSU) of a working circuit via a working optical fiber, (2) a protection OSU of a protection circuit via a protection optical fiber, and (3) one or more optical network terminals (ONTs), where the protection OSU has a protection burst mode receiver (BMR) configured to receive an upstream optical signal from the optical splitter. The algorithm determines whether the protection OSU is functioning improperly. A reset pulse is applied at the protection BMR at a particular timing position and an attempt is made to interpret the current upstream cell received at the protection BMR. This process is repeated using different timing positions for the BMR reset pulse until the current upstream cell is correctly interpreted, e.g., based on the correct identification of an ATM header error correction (HEC) byte in the upstream cell. If, after a specified number of cycles, no upstream cells are correctly interpreted, then the protection circuit is determined to have failed. In one embodiment, the algorithm is based on a cell delineation procedure implemented as a state machine.
