The invention discloses an efficient mass data indexing method in cloud computing. According to the method, the node splitting history is recorded by use of a log on the basis of a distributed B-tree and the distributed B-tree is efficiently and simultaneously accessed based on the node splitting history, and therefore, the accessing and indexing efficiency of mass distributed data in the cloud computing environment can be effectively improved. The efficient mass data indexing method in the cloud computing is superior to an affair method because distributed locks need to be added to all nodes in the path from the root to a leaf node to be accessed in the affair method, and the efficient mass data indexing method only needs to lock the leaf node to be accessed; the efficient mass data indexing method is superior to a link method because the number of nodes to be traversed in the efficient mass data indexing method is smaller than that of the link method.

A means of power management and control via a reverse link of a CDMA or LTE network is disclosed. The protocol is set to superimpose itself in an agnostic way to the power management as one more layer of freedom is added. The adjustment depending on the power control is then derived by mismatch if too much power or antenna tuning to enhance the power. This is also following a table in the device that will adjust ECC in case of a MIMO transmission such as LTE as well as SAR. This will generate also a mean of a soft-handoff and load control on the base station.
