  • Patent number: 8565774
    Abstract: The present invention provides a serving-grant allocation method for a high-speed uplink packet access system. It includes these steps: a. Transmission of the serving-grant initial allocation message to mobile subscribers via network; b. The mobile subscriber decides whether setting the stored-secondary-grant is needed based on the initial allocation message description. If it is needed, then set the stored-secondary-grant to the value indicated in the aforementioned initial allocation message. The present invention solves problems such as the mobile subscriber can not allocate stored-secondary-grant during wireless channel allocation, or the primary/secondary grant can only allocate one out of the two, and the subsequent process issues that occur as a result of stored-secondary-grant not being set up during the initial allocation with the existing technology.

    Abstract: A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow.
