Method and apparatus for displaying a customized caller line identification
View Patent ↗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.
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.
