摘要:
A synchronization process, and associated apparatus, for placing database copies in match with one another by way of communications effectuated upon an air interface of a radio communication system. Hash functions are performed at a mobile node and at a network part upon mobile and network copies of database information. Comparison of the hash information formed therefrom provides a preliminary indication of whether the databases are in match with one another. If a determination is made that the databases are out of match, the data is compared, and the data is placed in match with one another responsive to such additional comparisons.
摘要:
Apparatus, and an associated method, for facilitating determination of whether database copies are in match with one another. A group hash is formed, associated with a group of data records of one of the database copies. The group hash is communicated, by way of a radio air interface, and the value of the group hash is compared with a corresponding value associated with a corresponding group of data records of the other database copy. If the values of the group hashes correspond, a determination is made that the groups of database records of the database are in match with one another. And, through communication of only a single group hash on the radio air interface, database correspondence of the group data records of the database copies are determined.
摘要:
Apparatus, and an associated method, for facilitating initiation of synchronization operations between databases in a radio communication system. A network-based database copy and a mobile-based database copy are maintained, and asynchronously updated. Synchronization operations synchronize the databases to place the databases in match with one another. Session state information is maintained, and communicated between the mobile node and the network part pursuant to start of a synchronization session.
摘要:
Apparatus, and an associated method, for placing data that is to be communicated pursuant to a synchronization session into efficient form. The synchronization session operates to synchronize database copies to place the data records of the database copies in match with one another. A coordinator coordinates change entries that are placed into a change listing. The coordination removes redundancies of the change entries so that the change entries that form a change history are maintained in efficient form, thereby to minimize the bandwidth required upon a radio air interface to communicate such information pursuant to a synchronization session.
摘要:
Apparatus, and an associated method, for facilitating synchronization of spaced-apart database copies, such as a mobile node database copy and a network-based database copy. A change list is created to list change indicia associated with changes made to a database. When synchronization operations are selected to be initiated, a change list lock locks the change list to prohibit subsequent alteration of the change list. And, a change list identifier uniquely identifies the change list, thereby to identify the change list to be associated with a particular synchronization session. Subsequent synchronization operations are thereafter performed.
摘要:
Apparatus, and an associated method, for facilitating synchronization of databases connected by way of a radio air interface. Changes to a data record embodied at the network part are detected by a detector. A mapping is performed by a mapper, and a synchronization request is generated by a synchronization request generator. The synchronization request is filtered by a filter, and converted into form to permit its efficient communication upon the radio air interface to a mobile node pursuant to a synchronization session.
摘要:
A limited-bandwidth network electronic data communication system (100) includes an electronic data transmission system (200) and a network terminal (300) in communication with the electronic data transmission system over a communications network (112). The electronic data transmission system includes a data receiver, a data formatter (218) and a data transmitter. The electronic data terminal includes a data receiver, a data reformatter and a data transmitter. Using the data transmitter an operator of the electronic data terminal transmits a request for transmission of an electronic message from the electronic data transmission system to the electronic data terminal. Upon receipt of the transmission request, the data formatter of the electronic data transmission system formats the electronic message in accordance with a default filtration parameter associated with the electronic data terminal, and assembles the electronic message as part of an electronic data package. Alternately, the retransmission request may include at least one data filtration parameter defining a desired alternate resolution for the electronic message, in which case the data formatter of the electronic data transmission system formats the electronic message in accordance with the specified filtration parameter. When the formatting step is completed, the data transmitter of the electronic data transmission system transmits the electronic data package to the electronic data terminal. Upon receipt of the electronic data package, the data reformatter of the electronic data terminal extracts the electronic message from the data package for review by the operator of the electronic data terminal.
摘要:
A limited-bandwidth network electronic data communication server includes an electronic data transmission server and a network terminal in communication with the electronic data transmission server over a communications network. The electronic data transmission server includes a data receiver for receiving a request for transmission of an e-mail attachment to a network terminal over a communications network. The e-mail attachment includes content and data defining the presentation of the content. A data processing system is in communication with the data receiver for converting the e-mail attachment into a less memory-intensive data format. The data processing system is configured to perform the conversion by extracting the content from the e-mail attachment without the presentation data. A data transmitter is in communication with the data processing system for transmitting the extracted content to the network terminal over the communications network without the presentation data.
