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.
Claims17
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 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 a first temporary block flow (TBF) for the first wireless uplink bearer for data block transfer;
- allocating 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 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.
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 computer-readable medium having conputer-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;
- and
- a processor, the processor coupled to the communication interface and to the computer-readable medium and configured to execute the instructions.
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 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.
