Abstract

A method and apparatus for a customized CLI comprise receiving, by a network element, a first SET-UP message from a transmitting device during a call set up. The network element then retrieves an identification of the transmitting device from the first SET-UP message and obtains a first Caller Line Identification (CLI) of the transmitting device corresponding to the retrieved identification. Further, the network element determines whether the first SET-UP message includes a first indicator and retrieves a data message from the first SET-UP message when the first SET-UP message includes a first indicator. The network element then adds the data message, the first CLI, and a second indicator to a second SET-UP message and transmits the second SET-UP message to a receiving device during the same call set up, for displaying a customized CLI on the receiving device, thereby alerting a user of the receiving device of an incoming call.

Claims

1. A method for providing a customized Caller Line Identification (CLI), the method comprising:

receiving, by a network element, a first SET-UP message from a transmitting device during a call set up;

retrieving, by the network element, a data message and an identification of the transmitting device from the first SET-UP message when the first SET-UP message includes a first indicator, wherein the first indicator includes a combination of bits in a user-user information element of the first SET-UP message;

obtaining, by the network element, a first CLI of the transmitting device corresponding to the retrieved identification;

adding, by the network element, the data message, the first CLI, and a second indicator to a second SET-UP message,

wherein the second indicator includes a combination of bits in a user-user information element of the second SET-UP message,

wherein each of the user-user information element of the first SET-UP message and the user-user information element of the second SET-UP message includes a first octet, a second octet, a third octet, and a fourth octet,

wherein the first octet includes a user-user information element identifier, the second octet includes a length of user-user contents, the third octet includes a user-user protocol discriminator, and the fourth octet includes user-user information;

transmitting, by the network element, the second SET-UP message to a receiving device during the call set up for displaying the customized CLI on a display of the receiving device, thereby alerting a user of the receiving device of an incoming call from the transmitting device.

2. The method of claim 1, wherein the first SET-UP message initiates a mobile originating call establishment and the second SET-UP message initiates a mobile terminated call establishment.

3. The method of claim 1, wherein the first indicator includes the combination of bits in the user-user protocol discriminator of the user-user information element of the first SET-UP message.

4. The method of claim 3, wherein the combination of bits in the first indicator is 00001100.

5. The method of claim 1, wherein the second indicator includes the combination of bits in the user-user protocol discriminator of the user-user information element of the second SET-UP message.

6. The method of claim 1, wherein the length of user-user contents indicates a number of octets corresponding to the user-user information, the user-user protocol discriminator indicates a coding used for the user-user information, and the user-user information comprises the data message.

7. A system for providing customized Caller Line Identification (CLI), the system comprising:

a network element, wherein the network element further comprises;

a first receiver, wherein the first receiver receives a first SET-UP message from a transmitting device during a call set up;

a first processor, coupled to the first receiver, wherein the first processor retrieves a data message and an identification of the transmitting device from the first SET-UP message when the first SET-UP message includes a first indicator, obtains a first CLI of the transmitting device corresponding to the retrieved identification, and forms a second SET-UP message comprising the data message, the first CLI, and a second indicator_s

wherein the first SET-UP message initiates a mobile originating call establishment and the second SET-UP message initiates a mobile terminated call establishment,

wherein each of a user-user information element of the first SET-UP message and a user-user information element of the second SET-UP message includes a first octet, a second octet, a third octet, and a fourth octet,

wherein the first octet includes a user-user information element identifier, the second octet includes a length of user-user contents, the third octet includes a user-user protocol discriminator, and the fourth octet includes a user-user information; and

a first transmitter, coupled to the first processor, wherein the first transmitter transmits the second SET-UP message to a receiving device during the call set up for displaying the customized CLI.

8. The system of claim 7, wherein a length of the identification of the transmitting device is shorter than a length of the data message.

9. The system of claim 7, wherein the first indicator includes the combination of bits in the user-user protocol discriminator of the user-user information element of the first SET-UP message.

10. The system of claim 9, wherein the combination of bits in the first indicator is 00001100.

11. The system of claim 7, wherein the second indicator includes the combination of bits in the user-user protocol discriminator of the user-user information element of the second SET-UP message.

12. The system of claim 7, wherein the length of user-user contents indicates a number of octets corresponding to the user-user information.

13. The system of claim 7, wherein the user-user protocol discriminator indicates a coding used for the user-user information.

14. The system of claim 7, wherein the user-user information comprises the data message.
