Abstract: Method and apparatus for provisioning an e-mail service to a mobile terminal in an e-mail system that uses e-mail addresses comprising a domain part. The apparatus maintains a list of good setting parameter sets versus e-mail domain parts. It receives an e-mail address and user authentication information from a user and compares the domain part of the received address with domain parts in the list of good parameter sets. If a match is found, e-mail service is provisioned with the matching parameter set. If no match is found, the apparatus requests and receives further parameters from the user, including an e-mail server address, and provisions the e-mail service with the further parameters. If the provisioning with the further parameters is successful, the domain part and the further parameters are used to generate a new setting parameter set in the list of good setting parameter sets.

Abstract: Systems and methods for dynamic adjustment of keep-alive message intervals in a mobile network are disclosed. One embodiment of maintaining an IP connection between a mobile terminal and a network node over a network includes, detecting a rate with which the client-slide request are made from the mobile terminal, detecting a rate with which the client-slide request are made from the mobile terminal, sending, by the network node, keep-alive messages to the mobile terminal in an absence of network traffic through the IP connection between the mobile terminal and the network node, and/or further optimizing the time intervals between the keep-alive messages based on a cost to send the keep-alive messages in the network.

Abstract: A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing (2-2) an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, (2-4) keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring (2-6) the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection. Based on the monitored lengths of periods of inactivity, a maximum interval (TINT) between keep-alive messages is determined (2-8) such that the maximum interval meets a predetermined criterion of statistical confidence, and the interval between keep-alive messages is set (2-10) to the maximum interval (TINT).

Abstract: Methods and systems of connectivity for forwarding an e-mail message from an e-mail server to a mobile terminal having an e-mail address under the e-mail server are provided. An e-mail address may be associated with a permanent identifier and encryption information of the mobile terminal. After receipt of an e-mail message addressed using the e-mail address from the e-mail server, the e-mail message may be encrypted using the stored encryption information. The mobile terminal may be identified using the association between the e-mail address and the permanent identifier of the mobile terminal. The e-mail message may then be provided to a messaging center for forwarding to the identified mobile terminal. The mobile terminal can decrypt and/or unpack the message using the encryption information.

Abstract: A method for conveying e-mail traffic between an e-mail server (108) and a mobile terminal (102) which has an e-mail address (122A) under the e-mail server and permanent terminal identity (122B) and a temporary identity (122D) in an access network (114). A connectivity function (600) is operationally coupled to the e-mail server (108) and the access network (114). The connectivity function (120) encrypts e-mail traffic to the mobile terminal and decrypt e-mail traffic from the mobile terminal, by using encryption information (122C). The mobile terminal generates (2-1) a service activation code which comprises an identifier (124D) of the mobile terminal, encryption information (122C) and checksum information. The service activation code is conveyed (2-3, 2-4) via a secure channel (2-3) to an authenticating terminal (100), from which the identifier (124D) of the mobile terminal and the encryption information (122C) are conveyed to the connectivity function (600).

Abstract: Systems and methods for sharing an e-mail address between a host system (100) and a mobile terminal (102) addressable by a temporary wireless identity (122D) in an access network (114). A terminal identifier (122A) is assigned to the mobile terminal (102) or its user. The system comprises a connectivity function (600) and a messaging centre (110) that collectively maintain an association (610, 612) between the terminal identifier (122A), encryption information (122C) and the temporary wireless identity (122D). When detecting an e-mail message addressed to the terminal identifier (122A), the connectivity function encrypts the e-mail message with the encryption information (122C). The messaging centre determines the temporary wireless identity (122D) of the mobile terminal and transmits the encrypted e-mail message to the mobile terminal which receives and decrypts the encrypted e-mail message.

Abstract: Methods and systems for forwarding an e-mail message from an e-mail server to a mobile terminal are provided. A messaging centre may store a permanent terminal identifier of the mobile terminal and an associated temporary identifier of the mobile terminal. The messaging center, upon receiving an e-mail message, may identify the mobile terminal based on an indication of the permanent terminal identifier included in the message and the stored association information. The e-mail message may then be transmitted to the mobile terminal using the temporary identifier associated with the permanent identifier of the mobile terminal.

Abstract: Methods and systems for maintaining mobile terminal information for secure email communications are provided. Information concerning multiple mobile terminals are maintained. Such information may include encryption information and an identifier for each mobile terminal. A service activation code that includes encryption information and an identifier from an authenticated user of the mobile terminal is received. The encryption information may be provided to a connectivity function for use in establishing an encrypted data channel. The established encrypted data channel may then be used to convey e-mail communications to and from the mobile terminal.
