The present invention is described further below in conjunction with accompanying drawing.
See also Fig. 3, for handling the flow chart of the method for controlling frame by frame protocol in the base station of the present invention; Described method comprises:
Step S11: determine the destination address of Frame Protocol processing unit at all uplink physical channels of Radio Link collection;
Step S12: when the Frame Protocol processing unit is received control frame, judge whether this control frame is the external circule power control frame, if, the target signal interference ratio in this control frame is taken out, send to uplink physical channel (step S13) according to destination address.
When base station node B receives that Radio Link (RL) that radio network controller (RNC) issues is set up request, create a NodeB communication context (NBCC, Node B Communication Context) process; Be used for resource management and signaling process under this NBCC.Described NBCC process is set up corresponding uplink physical channel (ULDPCH, Uplink Dedicated Physical Channel), down physical channel (DLDPCH, Downlink Dedicated Physical Channel), code combination transmission channel (CCTRCH, Coded Composite Transport Channel), and these information notification frame protocol processing unit.Can comprise a plurality of Radio Link collection (RL SET, Radio Link Set) under the NBCC, a RL SET can comprise a plurality of Radio Links (RL, Radio Link).In the WCDMA system, RNC can issue the external circule power control control frame, and this control frame is dealt into the FP processing unit by atm adaptation layer 2 (AAL2).The FP processing unit is by judging the type of this control frame, if this control frame is the external circule power control frame, the FP processing unit comes out to be dealt into corresponding uplink physical channel with target signal interference ratio (SirTarget) parameter extraction in this frame; Then, measure the signal interference ratio of uplink physical channel, its measure equation is: the spreading factor of signal interference ratio=(received signal code territory power/interference signal code domain power) downlink physical common signal channel, that is: SIR=(RSCP/ISCP) SF, wherein, SIR (Signal to Interference Ratio) is the ratio of signal and interference, RSCP (Received Signal Code Power, unbiasedmeasurement of the received power on one code.) be the received signal code domain power, i.e. the no inclined to one side measured value of the received signal on code word; ISCP (Interference Signal CodePower, the interference on the received signal) is the interference signal code domain power, i.e. the interference of received signal; SF refers to the spreading factor of downlink physical common signal channel (DPCCH).The reference point of described sir measurement is the reception antenna mouth.This value is measured acquisition from the DPCCH of Radio Link collection, if the Radio Link collection comprises a more than wireless links, the SIR that then reports be Radio Link concentrate the linearity of the SIR of each Radio Link to add up and, in addition, if diversity reception mode is adopted in the sub-district of NodeB, then the SIR of Radio Link is the linearity of the SIR on each reception antenna sum that adds up.Then, judge that whether this signal interference ratio of measuring uplink physical channel is greater than the target signal interference ratio that takes out, if notifying user equipment reduces the power of this upward signal from the external circule power control frame; Otherwise notifying user equipment improves the power of upward signal.If this control frame is not the external circule power control frame, then the Frame Protocol processing unit is just handled according to other Frame or control frame.
See also Fig. 4, be the flow chart of setting up a Radio Link of the embodiment of the invention.Its process of setting up link comprises:
Step M11: when the base station receive that radio network controller issues set up the Radio Link request time (require to set up and once set up two links), base station communication context NBCC process is created in the base station;
Step M12: described NBCC process is set up with the request of article one Frame Protocol and the request of second Frame Protocol of Frame Protocol processing unit respectively or is set up the request of two Frame Protocol processing units simultaneously, the Frame Protocol processing unit obtains the destination address of the Radio Link of Radio Link collection under this NBCC process, and replys the Frame Protocol processing unit and set up response;
Step M1 3:NBCC process is received and is replied Radio Link to radio network controller and set up response when response is set up in the answer of Frame Protocol processing unit.
As shown in Figure 4, be two links of a link setup.Described link is used for Signalling exchange, conversation or data processing, belongs to two different link set RLSET respectively, and a Frame Protocol FP processing unit is arranged under each RLSET.Set up in the request message in NBCC process and Frame Protocol processing unit 1, uplink physical channel ULDPCH number of article one Radio Link (RL1), the demodulating unit at RL1 place number can be brought Frame Protocol processing unit 1; It is as shown in table 1 that Frame Protocol is set up the message structure of asking:
Table 1
| IE/Group Name | Semantics description |
| Message Type | Type of message |
| NddCpuId | Demodulating unit ID |
| ULDPCH ID | With reference to ULDPCH ID |
| abData | FP sets up other message parameters |
Equally in setting up second Frame Protocol request message, can number bring Frame Protocol with uplink physical channel ULDPCH number of RL2, the demodulating unit at RL2 place and handle FP unit 2.Like this when setting up link, each Frame Protocol processing unit under this NBCC just obtains the demodulating unit number of this Frame Protocol processing unit place RL SET, with reference to ULDPCH number.When each Frame Protocol processing unit is received control frame, judge according to the type of this control frame whether this control frame is the external circule power control frame, if this control frame is the external circule power control frame, just the target signal interference ratio (SirTarget) with this control frame takes out, and sends on its corresponding reference uplink physical channel ULDPCH to handle.Measure the signal interference ratio of signal in this uplink physical channel then according to described formula: SIR=(RSCP/ISCP) SF, judge that more whether this signal interference ratio is greater than described target signal interference ratio, if greater than, illustrate that this upward signal is stronger, notifying user equipment reduces this user's transmitting power, if less than, a little less than illustrating that upward signal, notifying user equipment improves this user's transmitting power.So that the Frame Protocol processing unit is directly transmitted the control frame of receiving, be convenient to control.
Please consulting Fig. 5 again, is the flow chart of a Radio Link of deletion.The process of its deletion Radio Link comprises:
Step N11: when the NBCC process is received the deletion Radio Link request that radio network controller issues, (require deletion article one Radio Link RL1), directly delete the channel of this Radio Link correspondence, and variation has taken place, the information of this variation of request renewal in notification frame protocol processing unit corresponding reference uplink physical channel;
Step N12: after the Frame Protocol processing unit is received this information requested, upgrade the information of this Radio Link collection, and reply response, and the NBCC process has been deleted response to radio network controller answer link after receiving response to the NBCC process.
As shown in Figure 5, if there are two Radio Link collection to be respectively under the described NBCC process: RL SET1, RL SET2.Comprise two wireless links under the described Radio Link collection RL SET1, be respectively: Radio Link RL1 and Radio Link RL2 (wherein, RL1 is a reference link); Comprise a wireless links RL3 under the described Radio Link collection RL SET2, under each Radio Link collection RL SET a Frame Protocol processing unit is arranged.When the NBCC process is received the deletion Radio Link RL1 solicited message that radio network controller issues, directly delete the channel of this Radio Link correspondence, because the reference RL1 of RL SET1 changes, described NBCC process is with the information notification frame protocol processing unit 1 of described deletion RL1, being that Radio Link RL1 is pairing with reference to uplink physical channel variation has taken place, the information that the request update request should change, wherein the message structure of this Frame Protocol processing unit update request is as shown in table 2:
Table 2
| IE/Group Name | Semantic description |
| Message Type | Type of message |
| NddCpuId | Demodulating unit ID |
| ULDPCH ID | With reference to ULDPCH ID |
| abData | Other message parameters of FP information updating |
That is to say, when NBCC process-kill Radio Link RL1, these information need be upgraded by Frame Protocol update inquiry information notification frame protocol processing unit 1.So that when the Frame Protocol processing unit is received control frame again, control frame is forwarded in the uplink physical channel of corresponding Radio Link, can in time handle the control frame of receiving according to new corresponding relation.
Therefore, after the Frame Protocol processing unit is received the control frame that radio network controller (RNC) issues, earlier judge whether this control frame is the external circule power control frame, if external circule power control frame, the target signal interference ratio that then takes out in this control frame directly is transmitted to corresponding uplink physical channel, does not transmit processing and do not need to arrive first base station applies unit NBCC.Because the present invention reduced this step, thereby reduced propagation delay time end to end, increased control accuracy, reduced the complexity of system loading and system.
In addition, the present invention is not only for setting up and practicality during the deletion Radio Link, and for Radio Link increase, the reprovision flow process is practical equally.Promptly when the reference ULDPCH under a certain RLSET under this NBCC process changes, need the NBCC process in time to notify each Frame Protocol processing unit, promptly send a piece of news and notify its corresponding Frame Protocol unit by the NBCC process, this notice is when the Frame Protocol processing unit is set up solicited message, and the entity of the pairing demodulating unit of Frame Protocol processing unit carried out when number changing.Described message mainly comprises the uplink physical channel number of this user's correspondence, when receiving control frame with convenient Frame Protocol processing unit, according to up-to-date this user down the entity of corresponding demodulating unit number transmit this control frame.So that FP module forwards control frame.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
