System and method for provision of a second line service on mobile telephone

Abstract

A method for routing calls between a third party telecommunications device (“TD”) and a subscriber TD associated with a primary service and a second line service (“SLS”) involves associating the SLS number of the subscriber, the primary number of the subscriber and the primary number of a third party via a common relationship number. Calls directed from a third party to the SLS number of a subscriber are routed to an SLS platform and redirected to the subscriber TD. Calls directed from the subscriber TD to the third party use the relationship number to route the call to the SLS platform. The combination of the primary service number and the relationship number identifies the third party number for call completion. Calls can be directed to and from an SLS number of a subscriber TD using a combination of protocols such as ISUP, CAP and SIP.

What is claimed is: 
     
         1 . A method for enabling a standard mobile telephone that is provisioned with a primary telephone number issued by a service provider to make and receive calls that are associated with a second network recognizable telephone number, the method comprising the actions of:
 a special server that is communicatively coupled to a telecommunications network selecting a second line service telephone number to be associated with the standard mobile telephone;   the special server receiving a communication request initiated by a first mobile device that was used to dial the second line service telephone number without the inclusion of a prefix or suffix;   the special server identifying the standard mobile telephone that is associated with the second line service telephone number;   the special server identifying the primary number provisioned on the standard mobile telephone;   the special server establishing call over a channel that is at least partially based on a cellular communications channel between first mobile device and the standard mobile telephone, the communications channel being created by terminating a call from the first mobile device to the primary telephone number provisioned on the standard mobile device; and   the special server setting the caller ID field associated with the call to the second line service telephone number to enable the standard mobile telephone to identify the call as being between the first device and the second line service telephone number associated with the standard mobile telephone.   
     
     
         2 . The method of  claim 1 , wherein the standard mobile telephone can initiate a communication to second device such that the communication is associated with the second line service telephone number by initiating the communication using an application running on the particular mobile telephone that initiates the communication such that the communication is routed to the special server. 
     
     
         3 . The method of  claim 1 , wherein the standard mobile telephone can initiate a communication to a second device such that the communication is associated with the second line service telephone number by initiating the communication using a special number that is routed to the special server when received within the telecommunications network, wherein the special server associates the special number with the terminating number of the second device and the second line service telephone number of the standard mobile telephone. 
     
     
         4 . The method of  claim 1 , further comprising the special server, subsequent to receiving the communication request initiated by a first mobile device, performing the actions of:
 selecting a special network recognizable number;   associating the special network recognizable number with the second line service telephone number dialed by the first mobile device and a primary number associated with the first mobile device;   providing the special network recognizable number to the standard mobile telephone.   
     
     
         5 . The method of  claim 4 , further comprising the actions of:
 the special server receiving a standard mobile telephone initiated communication request, the communication request being directed to the special network recognizable number;   the special server identifying the second line service telephone number and the first mobile device primary number associated with the special network recognizable number;   the special server establishing call over a channel that is at least partially based on a cellular communications channel between first mobile device and the standard mobile telephone, the communications channel being created by terminating a call from the standard mobile telephone to the primary telephone number provisioned on the first mobile device; and   the special server setting the caller ID field associated with the call to the second line service telephone number to enable the first mobile device to identify the call as being between the first mobile device and the second line service telephone number associated with the standard mobile telephone.
