求助：分段查询记录

有如下记录
phonenum logintime status
15308615031 2011-09-04 00:01:51 熄火
15308615031 2011-09-04 00:01:52 熄火
15308615031 2011-09-04 00:01:53 停车
15308615031 2011-09-04 00:01:54 停车
15308615031 2011-09-04 00:01:55 熄火
15308615031 2011-09-04 00:01:56 熄火
15308615032 2011-09-04 00:01:52 停车
15308615032 2011-09-04 00:01:53 停车
15308615032 2011-09-04 00:01:54 熄火
15308615032 2011-09-04 00:01:55 熄火

怎么样通过存储过程得到如下格式的结果啊

号码 熄火开始时间 熄火结束时间
15308615031 2011-09-04 00:01:51 2011-09-04 00:01:52
15308615031 2011-09-04 00:01:55 2011-09-04 00:01:56
15308615032 2011-09-04 00:01:54 2011-09-04 00:01:55

请高手指点啊

为了思路清楚，用CTE写了个。。

与这个的差别就在于没有合并列值
