Method and system for wireless network-based messaging service message delivery

A system for delivering messages to a wireless access terminal, the system comprising:

• a messaging center in communication with a 1xEV-DO network, the messaging center arranged to receive a message having a telephone number as a destination address for delivery to the wireless access terminal, the messaging center having:
• a storage device storing a mapping between the telephone number, a mobile static identifier corresponding to a user of the wireless access terminal, and an IP address of the wireless access terminal in the 1xEV-DO network, the mapping between the telephone number and the IP address being based on a correspondence between the telephone number and the mobile static identifier;
• the mobile static identifier including a user id and a domain;
• and
• a central processing unit in communication with the storage device, the central processing unit being configured to:
• evaluate the mapping to determine the IP address of the wireless access terminal in the 1xEV-DO network;
• and
• transmit the message to the wireless access terminal using the 1xEV-DO network.

A non-transitory computer-readable storage medium storing a computer program which when executed performs a method for delivering messages constructed in a first communication protocol to a wireless access terminal in a communication network having a second communication protocol different from the first communication protocol, the method comprising:

• receiving a message in the first communication protocol for delivery to the wireless access terminal;
• storing a mapping between a first destination address corresponding to a first communication protocol destination address of the wireless access terminal in the first communication protocol, a mobile static identifier including a user id and a domain, and a second communication protocol destination address corresponding to a destination address of the wireless access terminal in the communication network, the mapping between the first communication protocol destination address and the second communication protocol destination address being based on a correspondence between the first communication protocol destination address and the mobile static identifier;
• evaluating the mapping to determine the second protocol destination address of the wireless access terminal in the communication network;
• and
• transmitting the message to the wireless access terminal using the second protocol destination address and the communication network.
