A method and apparatus are disclosed that enable: (i) applications that are external to a telecommunications terminal, rather than the user, to initiate the delivery of content to the terminal, and (ii) the terminal to determine, based on the state of the terminal, whether or not to provide the content to a user. The 'state' of the terminal is determined by one or more of (i) user-driven states, (ii) data states, and (iii) call states. When the terminal's state is considered, as in accordance with the illustrative embodiment of the present invention, the readiness of the user and terminal to accept and process the content are accounted for, and as a result the content does not interfere.

Message handling based on the state of a telecommunications terminal

A method and apparatus are disclosed that enable a telecommunications terminal to securely receive unsolicited content from applications that are external to the terminal. In particular, the present invention enables the terminal to control the interaction with external applications by using a secure, two-task process. In the two-task process of the present invention, the execution of the second task is based on verifying the trustworthiness of address information that is provided in the first task. This is in contrast to a one-task process, in which an untrustworthy server that provides content might hide its own address by substituting a legitimate address.

Handling unsolicited content at a telecommunications terminal

A protocol controls communications between a master unit and a plurality (M) of slave units connected thereto. The master unit sends a downlink message over a first communication path to the M slave units, the downlink message including a number N of information bytes, where N.gtoreq.M, each byte except a last byte comprising a data portion followed by a first predetermined control bit and the last byte comprising a status portion followed by a second predetermined control bit. The master unit receives uplink messages over a second communication path from the M slave units, the uplink messages having the same format as downlink messages. A third communication path connects between the master unit and the M slave units enabling a first slave unit to signal other slave units of the first slave unit's desire to send information to the master unit.
