  • Patent number: 8826007
    Abstract: To validate a received certificate issuance notification message, a device may verify that the certificate issuance notification message conforms to expected norms or authenticate a signature associate with the certificate issuance notification message. Upon validating, the device may then transmit a uniform resource locator, extracted from the certificate issuance notification message, to a network entity configured for processing certificate issuance.

  • Patent number: 8483727
    Abstract: A method, server and system for setting the size of email messages sent to mobile communications devices is provided. In one example embodiment, a method for processing email messages sent to a mobile communications device is provided, comprising: receiving an email message having message content that contains at least a first type of content and a second type of content that is different from the first type; parsing the received email message to determine a quantity of the first type content contained in the email message until a predetermined first content quantity limit is reached, or until the end of the received email message is reached if the first content quantity limit is not reached first; and sending the message content that corresponds to however much of the received email message was parsed to mobile communications device.

  • Patent number: 8341709
    Abstract: Rather than managing a certificate chain related to a newly issued identity certificate at a terminal to which a wireless device occasionally connects, a certificate server can act to determine the identity certificates in a certificate chain related to the newly issued identity certificate. The certificate server can also act to obtain the identity certificates and transmit the identity certificates towards the device that requested the newly issued identity certificate. A mail server may receive the newly issued identity certificate and the identity certificates in the certificate chain and manage the timing of the transmittal of the identity certificates. By transmitting the identity certificates in the certificate chain before transmitting the newly issued identity certificate, the mail server allows the user device to verify the authenticity of the newly issued identity certificate.

  • Patent number: 8126976
    Abstract: A method, server and system for managing the delivery of email messages in multiple parts is provided. A method for sending email messages in multiple parts to a mobile communication device, comprises receiving a request for additional content from a mobile communication device in respect of an email message for which a selected part of the content has been previously sent to the mobile communications device; and determining if processing technology used to provide the previously sent selected part is compatible with currently available processing technology, and if compatible then processing additional content from the email message using the currently available processing technology and sending the processed additional content to the mobile communication device.
