METHODS AND SYSTEMS ALLOWING ACCESS TO A MESSAGING PLATFORM THROUGH A VISITED MESSAGING PLATFORM

摘要

Methods and systems to provide a particular subscriber of a messaging system with access to a selected messaging platform (SMP) by making a call to a pilot number from a line number other than a line number of the subscriber. The call is routed to the SSP serving the line number from which the call originated. Based on the use of the pilot number, the SSP receives instructions from an intelligent network element (INE) to route the call to a messaging platform serving the line number from which the call originated. If the messaging platform receives a backout indicator in the call, then the messaging platform provides a backout notice to the SSP. The SSP engages in an exchange with the INE so as to result in the SSP obtaining a selected number from the particular subscriber and providing the selected number to the INE. The selected number is used by the INE to obtain an address for the SMP. The INE then instructs the SSP to route the call to the address for the SMP.
