Abstract
Abstract An improved method and system for limiting data packet transmission within a digital mobile telephone communication network, such as a code division multiple access (CDMA) mobile telephone communication network, by discarding unsuccessfully transmitted radio link protocol frames is disclosed. A code division multiple access (CDMA) mobile telephone communication network includes a mobile telephone, a base station, a mobile switching center, and a network Interworking Function. Within the CDMA mobile telephone communication network, each point-to-point protocol data packet is typically divided into multiple radio link protocol frames before their transmissions over an air link. In accordance with a method and system of the present invention, a marker bit is provided for each of the radio link protocol frames. The marker bit can be part of the frame header and will be removed before air link transmission. The marker bit of a first one of the radio link protocol frames is set to a first logical state (such as a logical “1”) and the rest of the radio link protocol frames are set to a second logical state (such as a logical “0”). In response to an unsuccessful transmission of one of the radio link protocol frames, all of the radio link protocol frames within the same point-to-point protocol data packet having the marker bit set to the second logical state are discarded, after a predetermined number of unsuccessful re-transmission attempts.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
115 words
A method for limiting data packet transmission within a mobile telephone communication network, wherein said mobile telephone communication network includes a mobile telephone, a base station, a mobile switching center, and a network interworking function, wherein said data packet transmission includes a plurality of radio link protocol frames formed by dividing a point-to-point data packet, said method comprising the steps of: in response to an unsuccessful transmission of one of said radio link protocol frames, performing a predetermined number of re-transmission attempts; and after said predetermined number of re-transmission attempts are considered unsuccessful, discarding all of said radio link protocol frames subsequent to said unsuccessful transmitted radio link protocol frame within said point-to-point data packet.
Claim 2
Independent Claim
115 words
A method for limiting data packet transmission within a mobile telephone communication network, wherein said mobile telephone communication network includes a mobile telephone, a base station, a mobile switching center, and a network interworking function, wherein said data packet transmission includes a plurality of radio link protocol frames formed by dividing a point-to-point data packet, said method comprising the steps of: in response to an unsuccessful transmission of one of said radio link protocol frames, performing a predetermined number of re-transmission attempts; and after said predetermined number of re-transmission attempts are considered unsuccessful, discarding all of said radio link protocol frames subsequent to said unsuccessful transmitted radio link protocol frame within said point-to-point data packet.
