Abstract:
Text messages with alphanumeric addresses are delivered to mobiles and external short message entities (ESMEs) which do not support alphanumeric addressing, providing meaningful fallback handling. Additionally, the invention enables delivery of SMPP messages from ESME or SMPP networks which can only originate numeric addresses, yet provide for mapping to alphanumeric addresses for delivery to the mobile. A two-way mapping is provided between alphanumeric addresses and S-S short-codes to enable delivery of text messages with alphanumeric addressing in networks which contain mobiles and/or ESME's that lack support of alphanumeric addressing.
