System and method for adaptive message retransmission
View Patent ↗A method and network controller ( 200 ) with a radio network controller ( 206 ) that transmits ( 302 ) a first signaling message to a communication device ( 108 ). The first signaling message includes extended information that some communications devices ( 108 ) are expected to be unable to process. The radio network controller ( 206 ) further transmits ( 312 ) a second signaling message that includes substantially all information that is contained within the first signaling message except for the extended information. The method and network controller ( 200 ) also includes a signaling message retransmission controller ( 208 ) communicatively coupled to the network controller, that identifies information contained within the extended information and indicates the extended information to the radio network controller ( 206 ).
1. A method for managing message transmission in a wireless communications network, the method comprising:
transmitting a first signaling message to a mobile device, the first signaling message comprising extended information, wherein the extended information comprises country specific information that is transmitted within messages conforming to a wireless communications protocol in fewer than all countries;
determining whether receipt and processing of the first signaling message has been successfully acknowledged;
when receipt and processing of the first signaling message has not been successfully acknowledged,
receiving a response to the first signaling message from the communication device indicating that the communication device rejected the first signaling message because of the country specific information; and
transmitting a second signaling message that comprises substantially all information contained within the first signaling message except for the country specific information.
2. The method of claim 1 , wherein the first signaling message complies with an IS-2000 protocol definition and wherein the country specific information comprises data contained within an Extended Record Type-International information record.
3. The method of claim 1 , wherein the first signaling message complies with an IS-2000 protocol definition and is an Alert with Information message containing the country specific information in an Extended Record Type-International information record; and
wherein the second signaling message comprises one of a flash message and a flash with information message, the one of the flash message and the flash with information message having the information Extended Record Type-International information record removed.
4. A wireless network controller, comprising:
a radio network controller configured to:
transmit a first signaling message to a mobile device, the first signaling message comprising extended information, wherein the extended information comprises country specific information that is transmitted within messages conforming to a wireless communications protocol in fewer than all countries;
determine whether receipt and full processing of the first signaling message has been successfully acknowledged; and
when receipt and processing of the first signaling message has not been successfully acknowledged,
receive a response to the first signaling message from the communication device indicating that the communication device rejected the first signaling message because of the country specific information,
transmit a second signaling message that comprises substantially all information contained within the first signaling message except for the country specific information; and
a signaling message retransmission controller communicatively coupled to the radio network controller, configured to identify information that is contained within the country specific information and indicate the country specific information to the radio network controller.
5. The wireless network controller of claim 4 , wherein the first signaling message complies with an IS-2000 protocol definition and wherein the country specific information comprises data contained within an Extended Record Type-International information record.
6. The wireless network controller of claim 4 , wherein the first signaling message complies with an IS-2000 protocol definition and is an Alert with Information message containing the country specific information in an Extended Record Type-International information record, and
wherein the second signaling message comprises one of a flash message and a flash with information message, the one of the flash message and the flash with information message having the country specific information Extended Record Type-International information record removed.
7. A method for managing message transmission in a mobile device, the method comprising:
receiving, by a mobile device, a first signaling message comprising extended information, wherein the extended information comprises country specific information that is transmitted within messages conforming to a wireless communications protocol in fewer than all countries;
in response to receiving the first signaling message, sending by the mobile device, to a wireless network controller, a message indicating that the mobile device rejected the first signaling message because of the country specific information; and
receiving a second signaling message that comprises substantially all information contained within the first signaling message except for the country specific information.
