Methods, apparatus, and systems are provided for tracking and analyzing data of consumer activity. The tracked data can be organized (e.g. as stored in cache, RAM, hard drives) in certain types of tables, where the tables can be associated with certain tags (keys) for efficiently accessing the data. The organization and associations of the data can also provide simple mechanisms for manipulating the data to obtain results specifically relevant for a task, such as detection of fraud or prediction of consumer behavior to provide better customer service or new services. For example, the tables may contain counters that store the number of times that two correlated consumer events occur within specific time intervals of each other. Such time data can provide efficient determination of patterns of consumer activity.

A method and apparatus for distributing a plurality of session requests across a plurality of servers. The method includes receiving a session request and determining whether the received request is part of an existing session. If the received request is determined not to be part of an existing session, then the request is directed to a server having the lowest expected load. If, however, the request is determined to be part of an existing session, then a second determination is made as to whether the server owning the existing session is in a dispatchable state. If the server is determined to be in a dispatchable state, then the request is directed to that server. However, if the server is determined not to be in a dispatchable state, then the request is directed to a server other than the one owning the existing session that has the lowest expected load.

A backup administrator can backup files from a production server on any of a plurality of different bases. In particular, some files can be replicated on a changed-byte basis. In other cases, files can be backed up by replicating updated copies of the entire file, or even byte blocks of the file.

While a mobile station apparatus is receiving a plurality of frequency bands, effective determinations of wireless link synchronization can be achieved. The mobile station apparatus measures the reception qualities of a plurality of different downlink frequency band signals (DL_CC1, DL_CC2) transmitted by one or more base station apparatuses and by the foregoing base station apparatuses. If all of the measured reception qualities are below a threshold value (Qout) (threshold value for determining downlink synchronizations), the mobile station apparatus determines that a downlink synchronization error has occurred, and then causes the downlink synchronization state to transition to an error detection part.

If no downlink synchronization has been recovered by the expiration of the downlink synchronization protection timer, the mobile station apparatus determines that an out-of-downlink-synchronization has occurred, and then releases individually designated radio resources and thereafter starts a cell reselection.
