Problems solved by technology
At the same time, user 2 served by base station 1 will be interfered by user 1
This has caused a problem that a base station interferes with other base station users, and at the same time, the users it serves are also interfered by other base station users.

Embodiment Construction
[0037] Such as figure 1 As shown, a preferred embodiment of a network scheduling method when different cells are applied with different time slot ratios proposed by the present invention includes:
[0038] Step 101: Among the base stations in adjacent cells, the base station using more downlink time slots performs full-band interference monitoring on all uplink time slots, and records the interference level I of each scheduling frequency band at time t i t ;
[0039] The LTE system is a broadband system, and the whole system is composed of N smallest scheduling frequency bands i, where i≤N, therefore, the scheduling frequency band may refer to the smallest scheduling frequency band;
[0040] Wherein, all uplink time slots refer to the uplink time slots of the base station itself that use more downlink time slots, and the uplink time slots used by base stations of adjacent cells that may cause interference.
[0041] Step 102: According to the interference level I of each sch...

The invention relates to networking scheduling method and device in the application process of different time slot proportions in different cells. The method comprises the following steps of: carrying out all-frequency-band interference monitoring on all uplink time slots by using a base station with more downlink time slots and recording interference levels of all scheduling frequency bands; andcalculating the average interference level according to the interference levels, wherein the scheduling frequency bands participate in the scheduling at the moment if the average interference level is less than a first preset threshold value, the scheduling frequency bands do not participate in the scheduling at the moment if the average interference level is more than or equal to the first preset threshold value, and the scheduling frequency bands are only scheduled to users with better coverage when the average interference level of the scheduling frequency bands which participate in the scheduling is more than a second preset threshold value and less than the first preset threshold value. In the invention, the interference monitoring is carried out on the base station before scheduling, and the scheduling frequency bands which can be avoided being interfered can be obtained by processing and analyzing the monitoring result, therefore, the interference in the process of different uplink and downlink proportioning networking of a TD-LTE (Time Division-Long Term Evolution) system is effectively restricted, and the favorable networking effect is achieved.
Description
technical field [0001] The invention relates to the field of communication technology base station scheduling, in particular to a network scheduling method and device when different cells use different time slot ratios. Background technique [0002] TD-LTE is TD-SCDMA Long Term Evolution, which refers to the long-term evolution of TD-SCDMA. TD-LTE supports a variety of different uplink and downlink ratios. In actual TD-LTE networking, due to service distribution problems, some base stations need to configure more downlink time slots to support higher downlink service rates. figure 1 In the actual network, the problems caused by the use of more downlink time slots by the base station are given. Base station 1 and base station 2 use different time slot ratios, and base station 1 uses more downlink time slot ratios, that is, when base station 1 is a downlink time slot, there is a case that base station 2 is an uplink time slot. During these time slots, base station 1 forms up...
