需要求出：

calcStart~calcEnd 在 2021-8-1 00:00:00~2021-8-31 23:59:59 和 2021-9-1 00:00:00~2021-9-30 23:59:59 两个自然月里 totalCount >= 4 按 sid 分组后的手机号出现的次数，怎么写？折腾半天，脑子有点晕。。

{"sid":"1007","count":1, "mobileSum":1},// 同一手机号满足 sid=1007 在 8月和9月 totalCount=1，记录数有 1 个
{"sid":"1007","count":2, "mobileSum":2},// 同一手机号满足 sid=1007 在 8月和9月 totalCount=2，记录数有 2 个
{"sid":"1007","count":3, "mobileSum":4},// 同一手机号满足 sid=1007 在 8月和9月 totalCount=3，记录数有 4 个
.
.
.
{"sid":"1007","count":10, "mobileSum":9},// 同一手机号满足 sid=1007 在 8月和9月 totalCount=10，记录数有 9 个
{"sid":"1004","count":1, "mobileSum":0},// 同一手机号满足 sid=1004 在 8月和9月 totalCount=1，记录数有 0 个
{"sid":"1004","count":2, "mobileSum":10},// 同一手机号满足 sid=1004 在 8月和9月 totalCount=2，记录数有 10 个
