System and method of messaging using min escape codes

Abstract

A method providing communication between an MSC and a mobile terminal in a wireless communications system including using the 10 digit MIN identifier for identifying the mobile terminal in all messages requiring a mobile terminal identifier sent from the MSC via a base station to the mobile terminal and using the 15 digit MIN-based IMSI identifier for identifying the mobile terminal in all messages requiring a mobile terminal identifier sent from the mobile terminal via the base station to the MSC. The method can also include deploying the use of 15 digit MIN-based IMSI identifiers in one MSC at a time. The invention also includes a system for providing mobile terminal identification information in a wireless system. The system includes a mobile terminal capable of receiving and responding to messages using a 10 digit MIN for identifying the mobile terminal and sending messages having a MIN-based IMSI identifier for identifying the mobile terminal. The system also includes an MSC capable of receiving and processing messages from the mobile terminal having the MIN-based IMSI identifier and sending messages to the mobile terminal using the 10 digit MIN identifier.

1 . A method of providing communication between a mobile terminal and a wireless communications system including a Mobile Switching Center (MSC) and a base station comprising: 
 sending a message from the MSC to the mobile terminal using a 10 digit identifier for identifying the mobile terminal, the 10 digit identifier being a 10 digit Mobile Identity Number (MIN); and    sending a message from the mobile terminal to the MSC in response to the message sent from the MSC using a 15 digit MIN-based International Mobile Station Identity (IMSI) identifier for identifying the mobile terminal, wherein the 15 digit MIN-based IMSI includes a 5 digit MIN Escape Code (MEC) and the MIN.    
   
   
       2 . The method defined in  claim 1  further comprising: 
 using the 10 digit MIN identifier for identifying the mobile terminal in all messages requiring a mobile terminal identifier sent from the MSC to the mobile terminal; and    using the 15 digit MIN-based IMSI identifier for identifying the mobile terminal in all messages requiring a mobile terminal identifier sent from the mobile terminal to the MSC.    
   
   
       3 . The method defined in  claim 1  wherein the step of sending the message to the mobile terminal includes paging the mobile terminal.  
   
   
       4 . The method defined in  claim 3  wherein the step of sending the message includes sending the 10 digit MIN identifier over the paging channel.  
   
   
       5 . The method defined in  claim 1  further comprising deploying the use of 15 digit MIN-based IMSI identifiers in one MSC at a time.  
   
   
       6 . The method defined in  claim 2  further comprising: 
 collecting 5 digit MECs programmed in mobile terminals communicating directly with their home systems; and    collecting 5 digit MECs programmed in mobile terminals visiting visited systems.    
   
   
       7 . The method defined in  claim 1  wherein the message sent from the mobile terminal to the MSC is an origination message.  
   
   
       8 . The method defined in  claim 1  wherein the message sent from the mobile terminal to the MSC is a registration message.  
   
   
       9 . A system for providing mobile terminal identification information in a wireless communications system comprising: 
 a mobile terminal capable of receiving and responding to messages using a 10 digit identifier for identifying the mobile terminal, the 10 digit identifier being a 10 digit Mobile Identity Number (MIN), and sending messages using a 15 digit MIN-based International Mobile Station Identity (IMSI) identifier for identifying the mobile terminal; and    a Mobile Switching Center (MSC) capable of receiving and processing messages from the mobile terminal using the 15 digit MIN-based IMSI identifier and sending messages to the mobile terminal using the 10 digit MIN identifier.    
   
   
       10 . The system defined in  claim 9  wherein the MSC is a home MSC.  
   
   
       11 . The system defined in  claim 9  wherein the MSC is a visited MSC.  
   
   
       12 . The system defined in  claim 9  wherein the MSC pages the mobile terminal by sending a message to the mobile terminal including the 10 digit Mobile Identity Number (MIN) for identifying the mobile terminal.
