Informing network about amount of data to be transferred
First Claim
Patent Images
1. A method for informing a network side about an amount of data to be transferred by means of data blocks in a wireless communication system, the method comprising:
- allocating, at a mobile station, a first wireless uplink bearer for a connection between a mobile station and a network, the first wireless uplink bearer being allocated for user data transfer;
establishing, at the mobile station, a first temporary block flow (TBF) for the first wireless uplink bearer for data block transfer;
allocating, at the mobile station, a second wireless uplink bearer for a connection between the mobile station and the network, the second wireless uplink bearer being a bearer using the first TBF for data block transfer;
adding to a data block, at the mobile station, a countdown value indicating the amount of data waiting for transmission using the first TBF for both the first wireless uplink bearer and the second wireless uplink bearer.

Abstract
When uplink signalling radio bearers steal capacity from a user bearer, at least the amount of data waiting for transmission on a TBF established for the user bearer should be informed to the network. This can be done by using separate countdown values for each radio bearer, using a first countdown value for the bearer the TBF was established for and a second countdown value which indicates the total amount of data on stealing bearers, or by calculating a common countdown value indicating the total amount of data on all bearers using the TBF.

7. A mobile station in a wireless communication system where data is transmitted by means of data blocks on radio bearers, the mobile station comprising:
-
a communication interface, the communication interface configured to send a data block; a non-transitory computer-readable medium having computer-readable instructions stored therein which are programmed to allocate a first radio bearer for a connection between a mobile station and a network;
establish a first temporary block flow (TBF) for the first radio bearer;
allocate a second bearer for the connection, the second bearer being a bearer using the first TBF for data block transfer;
calculate a countdown value, the countdown value indicating an amount of data waiting for transmission on the first radio bearer and the second bearer using the first TBF;
add the calculated countdown value to the data block; anda processor, the processor coupled to the communication interface and to the computer-readable medium and configured to execute the instructions. - View Dependent Claims (8, 9, 10, 11)

12. A network node in a wireless communication system where data is transmitted by means of data blocks on radio bearers, the network node comprising:
-
a communication interface, the communication interface configured to receive a data block; a non-transitory computer-readable medium having computer-readable instructions stored therein which are programmed to receive the data block on a first temporary block flow (TBF) established for a first radio bearer and allocated to a second bearer, the data block comprising a countdown value indicating an amount of data waiting for transmission on the first bearer and the second bearer;
identify the radio bearer the data block belongs to and maintain information on the countdown value. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for a network node, comprising:
-
receiving, at a network node, a data block on a first temporary block flow (TBF) established for a first radio bearer and allocated to a second bearer, the data block comprising a countdown value indicating an amount of data waiting for transmission on the first bearer and the second bearer; and identifying, at the network node, the radio bearer to which the data block belongs and maintaining information on the countdown value. - View Dependent Claims (19, 20, 21, 22, 23)

24. A non-transitory computer-readable medium having computer-readable instructions stored thereon, which, upon execution by a processor, cause the implementation of a set of operations for a mobile station, the operations comprising:
-
allocating a first radio bearer for a connection between the mobile station and a network; establishing a first temporary block flow (TBF) for the first radio bearer, to transfer data blocks; allocating a second bearer for the connection, the second bearer using the first TBF for data block transfer; calculating a countdown value indicating an amount of data waiting for transmission on the first radio bearer and the second bearer using the TBF; and adding the countdown value to a data block to be transmitted. - View Dependent Claims (25, 26, 27, 28)
