  • Patent number: 9215238
    Abstract: A method of handling cryptographic information in a communication comprising body elements and attachment elements to a mobile device includes the steps of determining if the communication includes an attachment element comprising cryptographic information and converting the attachment element into a body element upon determining that the communication includes an attachment element comprising cryptographic information.
    Type: Grant

  • Patent number: 8126842
    Abstract: 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.

  • Patent number: 7457631
    Abstract: 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.

  • Publication number: 20060080427
    Abstract: 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.

  • Publication number: 20050186975
    Abstract: 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.

  • Publication number: 20050181789
    Abstract: 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.

  • Publication number: 20050181790
    Abstract: 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.
