Step 501, terminal reside in second community, and second community corresponds to second frequency.
Step 502 estimates upstream rate of the terminal in first community, and monitors upper scanning frequency of the terminal in first community Whether rate meets current business demand.If satisfaction thens follow the steps 503, otherwise terminate process.Wherein the first frequency of first community Rate is greater than the second frequency of second community.
Base station is made an uproar by the downlink RSRP measurement result of first community, uplink bottom, and to estimate terminal with congestion situation small first Upstream rate when area.And monitor whether upstream rate of the terminal in first community meets current business demand.
Step 503, controlling terminal stop the descending carrier polymerization of the carrier wave of downlink first frequency and the carrier wave of second frequency.
Step 504, controlling terminal switch to first community by second community.Then terminate process.
The above process, as long as upstream rate of the terminal in first community can satisfy business demand, even if terminal is Upstream rate when two cells is higher, to be also switched to first community, guarantees the abundant frequency spectrum for preferentially using first community as far as possible Resource.
The whole implementation process of the transmission method of base station side of the embodiment of the present invention is, when user resides in first community (the corresponding first frequency of such as first community can be 3.5GHz), base station can pass through uplink cache size and uplink packet delay size It determines upstream rate when terminal resides in first community, can also obtain terminal by downlink RSRP and uplink MCS and reside in Upstream rate when first community.After upstream rate when obtaining terminal and residing in first community, judge that terminal resides in the Whether upstream rate when one cell meets current business demand.If not satisfied, the downlink RSRP by second community measures knot Fruit, uplink bottom are made an uproar and congestion situation etc. estimates upstream rate of the terminal in second community, if terminal is upper in second community Scanning frequency rate can meet business demand, then triggering terminal switches to second community by first community, configuration second community corresponding the The carrier wave of two frequencies be main carrier, the corresponding first frequency of first community carrier wave be secondary carrier, activate main carrier and secondary carrier Descending carrier polymerization.
When terminal resides in second community, base station can be made an uproar by the downlink RSRP measurement result of first community, uplink bottom Upstream rate of the terminal in first community is estimated with congestion situation, the upstream rate when terminal is in first community, which can meet, to be worked as When preceding business demand, then controlling terminal stops the descending carrier polymerization of the carrier wave of downlink first frequency and the carrier wave of second frequency, And controlling terminal switches to first community by second community.
