Problems solved by technology
[0004] However, since the Frame Number (Frame Number, FN) corresponding to each logical cell is different, it will affect the frequency hopping sequence of different time slots (Timeslot, TS) in the same sector in the super cell, so different logical cells in the super cell use The channel resources of the super cell need to be strictly separated in time slots. All the channel resources of the super cell need to be subdivided into multiple channel resource pools according to the time slots. Each logical cell has an exclusive channel resource pool. For different users in different logical cells The device cannot realize time slot resource reuse in the same channel resource pool, so the channel resource utilization efficiency of the super cell is low

The present invention discloses a frequency hopping sequence planning method and device, and relates to the communication field. The frequency hopping sequence planning method and device emable the logic cells in a super cell to share time slot resources of channel resources. The scheme of the frequency hopping sequence planning method comprises: using a frequency hopping sequence planning device to determine the frame numbers and the offset values of the frequency hopping sequences of the logic cells in the super cell which comprises at least two logic cells, computing offset value variables of the logic cells according to the frame numbers of the logic cells, correcting the offset values of the logic cells according to the offset value variables of the frequency hopping sequence, and sending the obtained corrected frequency hopping sequence offset values to a base station control device, so as to enable the base station control device to configure the corrected frequency hopping sequence offset values to corresponding logic cells. The frequency hopping planning method and device are used for frequency hopping planning.
Description
technical field [0001] The present invention relates to the communication field, in particular to a frequency hopping sequence planning method and device. Background technique [0002] At present, the GSM (Global System for Mobile communication, Global System for Mobile communication) combined cell merges frequency points of multiple cells, so that the number of frequency points used by GSM is reduced, while the coverage area remains unchanged, and the spectrum efficiency is improved. Different cells using the same frequency point form a super cell. [0003] Since the super cell needs to be based on a synchronous network, multiple sectors in the super cell need space division multiplexing. On the other hand, there will be continuous strong co-channel interference between user equipments of space division multiplexing, and SACCH (Slow Associated Control Channel, slow associated control channel) will continue to collide, resulting in a serious deterioration of the call drop r...
