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.

System and method for transmitting and utilizing attachments

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.

Apparatus, and associated method, for synchronizing databases connected by way of a radio air interface

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.
