  • Patent number: 10356083
    Abstract: A mobile communication device causes a communication session to be established with a host server of a communication network. The mobile device performs communication operations in the communication session for activating a communication service, such as a data synchronization service, with the host server. In the communication session, the mobile device also receives configuration information which includes information for use in constructing a request message for obtaining a digital certificate from a certificate authority (CA). After receipt of the configuration information, the mobile device constructs the request message for the digital certificate and causes it to be sent to the host server. In response, the host server requests and obtains the digital certificate from the CA on behalf of the mobile device, and thereafter “pushes” the received digital certificate to the mobile device. The mobile device receives the digital certificate and stores it for use in subsequent communications.

  • Patent number: 10015158
    Abstract: In one illustrative scenario, a mobile communication device causes a communication session to be established with a host server of a communication network. The mobile device performs communication operations in the communication session for activating a communication service, such as a data synchronization service, with the host server. In the communication session, the mobile device also receives configuration information which includes information for use in constructing a request message for obtaining a digital certificate from a certificate authority (CA). After receipt of the configuration information, the mobile device constructs the request message for the digital certificate and causes it to be sent to the host server. In response, the host server requests and obtains the digital certificate from the CA on behalf of the mobile device, and thereafter “pushes” the received digital certificate to the mobile device.

The mobile device receives the digital certificate and stores it for use in subsequent communications. The host server may be part of a local area network (LAN) which includes a wireless LAN (WLAN) adapted to authenticate the mobile device based on the digital certificate, so that the mobile device may obtain access to the WLAN.
