| HS-DSCH InitialCapacityAllocation | 1..<maxnoofPrioQueues> | |||
| >SchedulingPriority lndicator | M | 9.2.1.53H | ||
| >MaximumMAC-d PDU Size | M | MAC-d PDU Size9.2.1.38A | ||
| >HS-DSCH InitialWindow Size | M | 9.2.1.31Hb |
In the table 1, Scheduling Priority Indicator is used to indicate the dispatching priority of HS-DSCH formation; Maximum MAC-d PDU Size is used to indicate the size of maximum MAC-d PDU; HS-DSCHInitial Window Size is used to indicate the home window size of HS-DSCH.
Step 3, RNC judges in the RADIO LINK SETUP RESPONSE/RADIO LINKRECONFIGURATION READY message that receives whether carry HS-DSCH Initial CapacityAllocation IE, if carry above-mentioned cell in the message, then RNC is before receiving data Layer HS-DSCHCAPACITY ALLOCATION (distribution of HS-DSCH capacity) control frame, can once authorize according to HS-DSCH Initial Capacity Allocation IE, the particular content of this mandate is: it is individual to send HS-DSCH Initial Window Size (HS-DSCH home window size) to NodeB at most, size is the MAC-d PDU of Maximum MAC-d PDU Size; If RNC judges and does not carry HS-DSCH Initial Capacity AllocationIE in the message, then RNC does not carry out the process of transmitting of MAC-d PDU, and waits for the HS-DSCHCAPACITY ALLOCATION control frame that receives the next data Layer of NodeB transmission.
In the step 3 of particular note: for RNC, above-mentioned mandate can only be used once, if RNC does not still receive HS-DSCH CAPACITY ALLOCATION control frame after authorizing, then RNC must suspend transmission MAC-d PDU, and waits for that receiving NodeB transmits the HS-DSCHCAPACITY ALLOCATION control frame of coming.
Step 4, NodeB send HS-DSCH CAPACITYALLOCATION control frame according to the flow control strategy to RNC.Carry HS-DSCH Repetition Period (HS-DSCH sends and authorizes number of repetition) in the control frame, HS-DSCH Repetition Period both can be designated as limited number of repetition such as 1 time to 255 times, also can be designated as unlimited number of repetition (representing with 0).
Step 5, after RNC receives HS-DSCH CAPACITY ALLOCATION control frame, successfully started HSDPA flow control flow process, RNC carries out flow control according to the information in the control frame.
Can find out from foregoing description, present HSDPA flow control methods must comprise two processes, to be NodeB respond the process of RADIO LINK SETUP RESPONSE/RADIO LINKRECONFIGURATION READY message and NodeB to RNC sends the process of HS-DSCHCAPACITYALLOCATION control frame to RNC, and the HSDPA flow control process awaits further optimization.And, wait application scenarios and need to be fixed the user in the scene (professional such as VOIP) such as allocated bandwidth in that the Iub interface bandwidth is abundant, after RNC carries out initial authorization, also must be after receiving HS-DSCH CAPACITY ALLOCATION control frame, could send MAC-dPDU to NodeB, cause MAC-d PDU transmission delay longer.In addition, the HS-DSCH CAPACITYALLOCATION control frame of data Layer does not adopt affirmation mechanism, thereby has affected the reliability of HSDPA flow control technique scheme.

Embodiment
Base station in the embodiment of the present invention is carried at the HS-DSCH capacity assignment information in the key-course message and is sent to base station controller when sending the HS-DSCH capacity assignment information to the base station controller corresponding with it.The base station can be after successfully having set up the HSDPA channel, send the HS-DSCH capacity assignment information to base station controller, the base station also can send the HS-DSCH capacity assignment information to base station controller in other cases, and embodiment of the present invention does not limit the base station sends opportunity from the key-course message that carries the HS-DSCH capacity assignment information to base station controller.Setting up the HSDPA channel and can set up the HSDPA channel according to the RADIO LINK SETUP REQUEST message that base station controller sends for the base station here, also can set up the HSDPA channel according to the RADIO LINK RECONFIGURATION PREPARE message that base station controller sends for the base station, certainly, can also set up the HSDPA channel according to other modes for the base station, embodiment of the present invention does not limit the foundation that the HSDPA channel is set up in the base station.
HS-DSCH capacity assignment information in the embodiment of the present invention is: base station controller carries out the required information of HSDPA flow control.The information that the HS-DSCH capacity assignment information carries in can the HS-DSCHCAPACITY ALLOCATION control frame for data Layer, as send the interval, each sends maximum authorization value that interval can send, HS-DSCH transmission mandate number of repetition etc.The particular content that the HS-DSCH capacity assignment information comprises can determine that according to the network condition of reality embodiment of the present invention does not limit the particular content that the HS-DSCH capacity assignment information comprises.
Key-course message in the embodiment of the present invention can be for key-course message existing, that the base station sends to base station controller, such as RADIO LINK RECONFIGURATION READY message or RADIOLINK SETUP RESPONSE message etc.That is to say that embodiment of the present invention can on the basis that does not change message interaction process between existing, base station and the base station controller, be sent to base station controller with the HS-DSCH capacity assignment information.Key-course message in the embodiment of the present invention also can be for increasing the key-course message of transmission specially for sending the HS-DSCH capacity assignment information.Embodiment of the present invention does not limit the concrete manifestation form of key-course message.
When utilizing present existing key-course message to send the HS-DSCH capacity assignment information to base station controller in the base station, generally need to expand key-course message, so that key-course message can be carried the HS-DSCH capacity assignment information.When the base station is sent to base station controller with the HS-DSCH capacity assignment information by RADIO LINK SETUPRESPONSE/RADIO LINK RECONFIGURATION READY message, to the extended mode of RADIO LINK SETUP RESPONSE/RADIO LINK RECONFIGURATIONREADY message can for: the HS-DSCH initial capacity assignment information unit in the message is expanded.Certainly, embodiment of the present invention also can be expanded other information units in the message, to carry the HS-DSCH capacity assignment information.Embodiment of the present invention does not limit the concrete extended mode to key-course message.
Base station controller is after receiving the key-course message of base-station transmission, judge in this key-course message and whether carry the HS-DSCH capacity assignment information, base station controller carries the HS-DSCH capacity assignment information in judging key-course message after, base station controller extracts the HS-DSCH capacity assignment information from this key-course message, then, base station controller carries out the HSDPA flow control according to the HS-DSCH capacity assignment information that extracts.
After the base station adopts key-course message to send the HS-DSCH capacity assignment information to base station controller, under application scenes, the base station can no longer send the HS-DSCH capacity distribution control frame of data Layer to base station controller, for example for the HSDPA user with fixed-bandwidth, the base station can be after having set up the HSDPA channel for this user, the HS-DSCH capacity assignment information is carried in the RADIO LINKSETUP RESPONSE/RADIO LINK RECONFIGURATION READY message is sent to base station controller, after this, the base station can no longer send the HS-DSCH capacity distribution control frame of data Layer to base station controller, thereby when improving HSDPA flow control reliability, simplified HSDPA flow control flow process.Under other application scenarioss as in the abundant situation of Iub interface bandwidth, even the base station needs again to send to base station controller the HS-DSCH capacity distribution control frame of data Layer, before the base station sends HS-DSCH capacity distribution control frame, base station controller also can send MAC-d PDU according to the HS-DSCH capacity assignment information to the base station, and needn't after receiving the HS-DSCH capacity to distribute control frame, just send MAC-d PDU to the base station, thereby reduced the propagation delay time of MAC-d PDU, and then improved the delay performance of system.
No matter whether the base station sent the HS-DSCH capacity assignment information to base station controller, the base station can determine whether according to predetermined flow control strategy that all needs send the HS-DSCH capacity to base station controller and distribute control frame.The base station determine according to the flow control strategy that needs send to base station controller that the HS-DSCH capacity distributes control frame and sent the HS-DSCH capacity to base station controller distribute control frame after, base station controller should distribute control frame carry out the HSDPA flow control according to its HS-DSCH capacity that receives.The base station is when determining needs and send the HS-DSCH capacity and distribute control frame and base station controller to get access to the HS-DSCH capacity assignment information from key-course message to base station controller according to the flow control strategy, base station controller can carry out the HSDPA flow control according to the HS-DSCH capacity assignment information that carries in the key-course message always.The flow control strategy here then no longer sends the HS-DSCH capacity and distributes control frame etc. as for the HSDPA user with fixed-bandwidth and sent the HS-DSCH capacity assignment information by key-course message.
Both do not received the key-course message that carries the HS-DSCH capacity assignment information when base station controller, when also not receiving HS-DSCH capacity distribution control frame, then base station controller waits for that the key-course message that carries the HS-DSCH capacity assignment information or the HS-DSCH capacity that send the base station distribute control frame.
The below utilizes existing transmission of messages flow process to carry out that the HS-DSCH capacity assignment information is transmitted as example, the HSDPA flow control methods of 1 pair of embodiment of the present invention describes by reference to the accompanying drawings with the base station.
Among Fig. 1, receive the key-course message that the base station controller transmission comes in step 100, base station, this key-course message is the key-course message that the HSDPA channel is set up in base station controller indication base station.The HSDPA channel is set up according to this key-course message in the base station.The base station is carried at the HS-DSCH capacity assignment information in the response message of above-mentioned key-course message and is sent to base station controller.The response message here belongs to key-course message.
Step 140, base station controller carry out the HSDPA flow control according to the HS-DSCH capacity assignment information that extracts.
In the description of above-mentioned execution mode, base station controller can be the RNC in the WCDMA system, and the base station can be the NodeB in the WCDMA system.Embodiment of the present invention not only is applicable to the WCDMA system, and every system that carries out the HSDPA flow control by base station controller all can be suitable for.
The below is take the WCDMA system as the example example, the HSDPA flow control starting method of 2 pairs of embodiment of the present invention describes by reference to the accompanying drawings.
Among Fig. 2, step 200, RNC issue RADIO LINK SETUP REQUEST/RADIO LINK RECONFIGURATION PREPARE message to NodeB, and NodeB sets up the HSDPA channel with indication.
Receive the message that RNC sends to step 210, NodeB, and set up the HSDPA channel according to this message, then, respond RADIO LINK SETUP RESPONSE/RADIO LINKRECONFIGURATION READY message to RNC, this message can selectivity be carried among HS-DSCH InitialCapacity Allocation IE and the HS-DSCH Initial Capacity Allocation IE can carry the HS-DSCH capacity assignment information.The HS-DSCH capacity assignment information can reflect the key message in the HS-DSCHCAPACITY ALLOCATION control frame, and maximum authorization value, the HS-DSCH that can send such as transmission interval, each transmission interval send mandate number of repetition etc.
When carrying the HS-DSCH capacity assignment information with HS-DSCH Initial Capacity Allocation IE, embodiment of the present invention need to be expanded HS-DSCH Initial Capacity Allocation IE.The embodiment of HS-DSCH Initial Capacity Allocation IE after the expansion is as shown in table 2.
