Abstract: In a Time Division Multiple Access (TDMA) cellular system, there is provided a mechanism for synchronization and equalization comprising: providing synchronization information (S/S) sufficiently removed from the start of a TDM slot so as to maintain the integrity of that synchronization information (S/S) at adjacent cells and providing that synchronization information (S/S) not so far removed from the start of the slot as to necessitate adaptive equalization of information preceding the synchronization information (S/S) for sufficiently reliable recovery. The equalization is further enhanced by providing, roughly midway between the synchronization information (S/S) and the end of the slot, additional information (CC) upon which equalization may retrain. Accordingly, equalizers perform retrospective, non-adaptive equalization of information preceding the synchronization information (S/S), perform adaptive equalization of information following that synchronization information (S/S), and retrain utilizing known bit-sequences elsewhere within the TDM slot; the additional information (CC) comprises known bit-sequences identifying cells.

Abstract: A cellular system employs a subaudible signalling control protocol. The protocol includes transmitting supervisory related signals between the radiotelephone and one of the cell sites at a first subaudible digital bit rate, and transmitting data messages between the radiotelephone and said one of the cell sites at a second subaudible digital bit rate. Additionally, the system employs specific protocols involving alert, hand-off and call disconnect which accommodate the subaudible signalling, yet provide significant integrity and reliability advantages over previously known protocols.

Abstract: New devices (101) are added to an existing domain by obtaining domain information (e.g., domain name and private domain password) from devices (101) already in the domain that preferably are in close proximity. Once the domain information has been transferred from the device already in the domain to the device being added to the domain, the device being added to the domain contacts a key issuer (105) to complete its registration into the domain. The key issuer returns a DRM domain private key (206) as well as a DRM certificate (202). Both are utilized by the device to obtain and render digital content (204).

Abstract: An electronic wallet (100) is capable of storing at least one of a financial information and a balance. Additionally, the electronic wallet (100) is capable of selective call receiving (200) a wireless message including financial information relating to a balance and updating the balance in response to the wireless message.

Abstract: Devices (101) are assigned a unique, unalterable, identification or serial number (313) that acts as the devices "electronic" biometric. Any certificate (302) created by a key issuer will contain the device's assigned DRM public key and the device's electronic biometric data. When a consumer wishes to purchase new content (304) from a content provider (103), the consumer will send the DRM certificate containing its DRM public key and the biometric. The rights issuer will then create a license (306) that assigns the content in such a way that only a device with the particular biometric and DRM private key is allowed to render the content.

Abstract: A cryptographic apparatus for encrypting and decrypting digital words includes a mechanism that permits a cipher algorithm to be electronically stored after the manufacture of the apparatus. The storing mechanism includes at least one electrically erasable, programmable gate array containing a portion of the cipher algorithm and at least one random access memory device coupled to the array for storing digital data generated by the algorithm. A mechanism which is coupled to the gate array and memory device controls the execution of the algorithm for each digital word thereby decrypting encrypted digital words and encrypting non-encrypted digital words.
