The present invention discloses a method, system and device for transmitting an E-DCH Random Access Uplink Control Channel (E-RUCCH), where the method includes: a UE judging whether a plurality of E-RUCCH transmission processes temporally overlap; and if there is overlapping, then the UE selecting and performing one of the E-RUCCH transmission processes and returning scheduling information and the identifier of the UE to a base station over an E-RUCCH. The method addresses the problem of coordination between E-RUCCH transmission processes triggered due to various reasons in a TD-SCDMA system with the enhanced feature of CELL_FACH introduced thereto.

The disclosure discloses a method and system for reducing an amount of data transfer in data synchronization, in which the method comprises: identifying different data values in each data column within a changed source data table; coding data values in each data column, wherein, for each data column, different data values have different coding values; identifying different ChangeType and ChangeBits in data change history information; and generating a change matrix by using the coding values of different data values in each data column according to different ChangeType and ChangeBits. With the change matrix, data having the same change for different rows within an initial data change are merged into a same change row within the change matrix, thereby reducing amount of data transfer and improving synchronization efficiency.

Reducing an amount of data transfer in data synchronization

Techniques for reconstructing a target hierarchy tree structure from profiling data of a computer system according to a predefined relational model, so as to obtain profiling information of a certain selected node. The predefined relational model is defined in advance according to a hierarchy tree structure of the profiling data, and is stored in an external storage system. The hierarchy tree structures can be constructed dynamically as required, thus the occupied amount of a memory can be seduced and users can view the profiling data freely.
