Systems and methods are disclosed for notifying external message centers when a mobile device becomes available to receive a text message. One embodiment includes a message waiting system that identifies a failed delivery attempt of a text message to a mobile device that is unavailable, where the text message originated from an external message center. The system identifies routing information for the external message center based on the failed delivery attempt, generates a Message Waiting Indicator (MWI) record for the text message that includes the routing information for the external message center, and stores the MWI record. When the system identifies that the mobile device becomes available, the system identifies the MWI record that includes information on the failed delivery attempt to the mobile device, and sends a notification indicating that the mobile device is available to the external message center based on the routing information in the MWI record.

Message waiting notification to external message centers

A method and apparatus for communicating between entities of a wireless cellular telecommunications system in protocols extended from the standard IS-41 Protocols. In accordance with the invention, different pairs of entities can communicate using different extended protocol dialects. The extended protocol dialects can include extra operations codes, extra parameter identifiers, or both. The extended protocol between each pair of entities of the system is assigned, but can be changed by an appropriate message. Advantageously, the basic spectrum for extended protocols can be enlarged by allowing different extended protocols between different entities and/or by switching extended protocol dialects between specific entities.

Enhanced private parameter capability in IS-41 messages

A liner pipe comprising sections of polyethylene pipe connected by articulated gasketed joints of bell and spigot design which are specifically adapted for ease of compression lining of large diameter pipe with minimum disruption to surface traffic and pipeline flow.

Pipeline rehabilitation articulated gasketed-joint pipe

A method of rehabilitating buried pipelines by the introduction of a particular liner pipe comprising sections of polyethylene pipe connected by articulated gasketed joints of bell and spigot design which are specifically adapted for ease of lining large diameter pipeliner with minimum disruption to surface traffic and pipeline flow.
