  • Patent number: 7174177
    Abstract: A system and method for providing improved teleservice messaging to a mobile station in a wireless communication network are disclosed. In preferred embodiments, an indication is provided to a network sending entity of the maximum teleservice payload size that can be sent by the network sending entity to the mobile station via network receiving entities serving the mobile station. The payload size indication is utilized by the network sending entity to format the size of teleservice messages sent by the network sending entity to the mobile station via the network receiving entities.

  • Patent number: 6868274
    Abstract: A system (100) that is capable of transmitting a displayable message to a short message entity (102, 104 or 105) in more than one data package over a conveying network. The system (100) uses a capacity determiner (206) to determine a capacity of the conveying network for transmitting data. Based on this capacity of the conveying network, a fragmenter (204) divides the displayable message into fragments at an application protocol layer. The size of a fragment does not exceed the capacity of the conveying network. Finally, a packager (208) packages the fragments into data packages. The data packages are operable to be separately transmitted by a short message service over the conveying network. The data packages may include a reference parameter corresponding to the position of the fragment in the displayable message. Further, a reference parameter may indicate the total size of the displayable message being fragmented and packaged.

  • Patent number: 6778828
    Abstract: A system is provided for securely registering a new user's personal mobility information in a communications terminal having existing registrations. The terminal owner provides information needed to verify the owner's identity and authorizes registration of a specific new user identified by the new user's IMSI. The new user also provides information needed to verify the new user's identity, and requests the registration. A user identity module verifies the identity information provided by the terminal owner and new user, and through intermediaries including a serving system, negotiates with the new user's home system (home location register) to obtain subscription information and appropriate security information for the new user to permit system access. Registration is accomplished by storing this information in the user identity module.

  • Patent number: 5909651
    Abstract: In certain wireless communication systems, including at least some CDMA cellular systems, short messages can be delivered to mobile stations in a broadcast fashion using a common forward (downlink) channel sometimes referred to as the Paging Channel. Economy in the use of the Paging Channel can be achieved by using so-called slotted mode reception. In accordance with this mode, the infrastructure directs messages to a given mobile station only during time slots allocated to the particular group of mobile stations to which the given station belongs. These time slots recur according to a paging slot cycle having a specified length (expressed as a number of slots), or slot cycle index. Disclosed here is a further cycle, referred to as the Broadcast Paging Cycle, for use in implementing a service for broadcasting short messages (to many mobile stations). The Broadcast Paging Cycle has an index that is larger than, and incommensurable with, the paging slot cycle index.
