초록 ▼

A method for use in multicellular communication network system of the type having base stations and a plurality of remote stations. The method achieves reliable and fault tolerant synchronization between the stations in a call when a frequency hopping technique is used. The method includes steps for acquiring the frequency hop sequence by remote station and tracking the frequency hop sequence after acquisition in order to stay in synchronism. The method also provides for recovering from loss of synchronism and for staying in synchronism.

In a multicellular communications network system comprising base stations having different addresses and a plurality of remote stations incorporating a technique for frequency hopping wherein said base stations transmit information to remote stations using a sequence of frequency hops of different carrier frequencies, a method for generating and transmitting consecutive frames of data for synchronization during said transmission comprising the steps of: Step 1 generating frames of data to be transmitted from each of said base station to said remote stations, said frames including a header portion and a data transfer portion, Step 2 incorporating frequency hopping control information into said frame header portion by incorporating the address of said base station within the network, incorporating the time remaining in said frequency hop being used, incorporating the frame length of said frame and incorporating a list of the next hopping frequencies to be used in said sequence of changing frequency hopping sequence tracking technique, wherein said remote station switches to a given frequency for a given period of time equal to or greater than the length of a frame, and wherein said remote station monitors the header information of frames transmitted from a series of other bases of said network and selects another base as a new home base when paid SYNC state of operation is not achieved with a selected number of attempts, Step 3 transmitting a plurality of said frames from said base stations to said remote stations using a sequence of frequency hops having different carrier frequencies.
