Background technology
Along with the development of FMC (Fixed Mobile Convergence, fixing and mobile the fusion) technology, use IP technology carrying 3G business to become a kind of trend.In the prior art, base station controller, as RNC (RadioNetwork Controller, radio network controller) is connected with transmission network by GE (gigabit Ethernet) or FE (Fast Ethernet) link, Node B (base station) then can pass through FE link, E1 link or STM-1 (Synchronous Transport-1, Synchronous Transport Module level-N 1) link is connected with transmission network, perhaps also can be connected with described transmission network by N bar E1.Wherein, the side signal transmission between base station controller and the base station in, will be called down direction to the direction of base station by base station controller, be called up direction by the base station to the direction of base station controller.
In 3G network, mainly contain three class business: speech business, HSDPA business (High Speed DownlinkPacket Access, high speed downlink packet inserts) and HSUPA business (high speed uplink packetaccess, High Speed Uplink Packet inserts).Wherein, the up-downgoing flow of speech business is suitable substantially, and the HSDPA business mainly is a downlink traffic, and the HSUPA business then mainly is a uplink traffic.Therefore, different business also has different requirements to the bandwidth of the uplink and downlink transmission link between base station controller and the base station.
For being various traffic assignments bandwidth reasonably, can adopt following dual mode in the prior art:
Mode one: the up direction in the base station, distribute different logic ports for speech business, HSUPA business and signaling, send the upstream bandwidth of the variant business of bandwidth constraints by restriction to logic port.For example, suppose that certain physical port is the E1 mouth, the base station is connected with base station controller by this E1 mouth.No. 0 logic port, No. 1 logic port, No. 2 logic ports are bundled on this physical port.Simultaneously, be the different transmission bandwidth of each logic port configuration, like this, the bandwidth that HSUPA business, speech business, signaling will take own place logic port is respectively transmitted.
Mode two: the up direction in the base station, assign identical logic port for speech business, HSUPA business and signaling, and be the different different transmission priority queries of business setting.For example, signaling sends by No. 0 priority query, and the uplink traffic of speech business sends by No. 1 priority query, and the uplink traffic of HSUPA business sends by No. 2 priority queries.Like this, signaling and the voice bandwidth that will take can be guaranteed completely.And, also guarantee to send its uplink traffic for the HSUPA business as far as possible.And, for HSUPA is professional, can feeds back frame losing information by base station controller and indicate the base station whether to need to reduce the uplink traffic of HSUPA business.
But in realizing process of the present invention, the inventor finds:
For mode one, if the summation of the transmission bandwidth of three logic port configurations equals the words of ports physical bandwidth, so when speech business is relatively notr busy, the remaining that part of bandwidth of speech business can not be used for HSUPA is professional, therefore can't realize physical port bandwidth multiplexing between different business, bandwidth availability ratio is low.For mode two, if indicate the base station to reduce the transmitted traffic of HSUPA by base station controller feedback frame losing information, receive described feedback frame losing information to the base station from base station controller feedback frame losing information, begin to reduce the flow of HSUPA business again to the base station, the frame losing phenomenon can occur in the whole process.And if retransmit these frames, will cause the waste of bandwidth, also make bandwidth utilization low.

Embodiment
Elaborate below in conjunction with the technical scheme and the advantage thereof of accompanying drawing to the embodiment of the invention.
For improving the upstream bandwidth utilance of transmission link between base station controller and the base station, as shown in Figure 1, the embodiment of the invention one provides a kind of data transfer control system, comprise: base station controller 12 and at least one base station 11, wherein said base station 11 links to each other with described base station controller 12 in the mode that can communicate by letter.
Wherein, described base station 11 is used for sending the high speed uplink chain grouping access service data to base station controller 12, and obtains the residual cache time of high speed uplink chain grouping access service queue.When described residual cache time during, reduce described flow of high speed uplink grouping access service less than the congestion time threshold value; When described residual cache time during, increase described flow of high speed uplink grouping access service greater than congestion time threshold.Base station controller 12 is used to receive the high speed uplink chain grouping access service data that sent by described base station 11.
In this embodiment, described base station controller includes but not limited to RNC, and CBSC (CDMA centralized base-station controller)/GBSC (GSM centralized base-station controller) etc. also can comprise all radio network controllers.
Embodiment of the invention data transfer control system, by comparing with congestion time threshold value and congestion time threshold respectively in the residual cache time of base station side with the HSUPA service queue that gets access to, and, reduce the flow of described HSUPA business when described residual cache time during less than the congestion time threshold value; When described residual cache time during, increase the flow of described HSUPA business greater than congestion time threshold.By above description as can be seen, the embodiment of the invention is to regulate the flow of HSUPA business dynamically in base station side, just can regulate the flow of HSUPA business according to aforesaid judged result by base station self, therefore, the embodiment of the invention one described system has improved the upstream bandwidth utilance of transmission link between base station controller and the base station.
The embodiment of the invention two provides a kind of data transfer control method.In the embodiment of the invention two described methods, the uplink dispatching party of base station to, speech business, HSUPA business and signaling are assigned identical logic port, different business is by the formation transmission of the different priorities of same logic port.For example, signaling can be sent at highest-priority queue, speech business sends at inferior high-priority queue, and the HSUPA business sends in lowest priority queue.
As shown in Figure 2, the embodiment of the invention two described methods comprise the steps:
Step 21 in base station side, is obtained the residual cache time of high speed uplink chain grouping access service queue by the base station.
In this step, can obtain the residual cache time of HSUPA service queue in the following manner:
At first, in the given time, obtain the transmission rate of described high speed uplink chain grouping access service queue.The described scheduled time, but configured in advance or storage or setting arbitrarily.Wherein, described transmission rate is the byte number of HSUPA service queue transmission in the described scheduled time and the merchant of the described scheduled time.
Then, obtain the remaining cache number of described high speed uplink chain grouping access service queue.What described remaining cache number was total buffer memory number of HSUAP service queue with message number in the formation that the moment read that arrives the scheduled time is poor.Wherein, but also configured in advance of total buffer memory number of described HSUAP service queue.
At last, according to described remaining cache number, obtain the residual cache time of high speed uplink chain grouping access service queue.Described residual cache time can be calculated in such a way:
The remaining cache-time of HSUPA service queue=(remaining cache number * typical case bag is long)/transmission rate.Wherein, described typical case's bag is long to can be default value, perhaps sets in advance.
Step 22, when described residual cache time during less than the congestion time threshold value, described base station reduces described flow of high speed uplink grouping access service; When described residual cache time during greater than congestion time threshold, described base station increases described flow of high speed uplink grouping access service.
In this step, when described residual cache time during less than the congestion time threshold value, can generate congested feedback message, can reduce flow of high speed uplink grouping access service according to this message so that receive the unit or the module of described congested feedback message in the base station, after receiving following congested feedback recovery message, no longer reduce flow.As a same reason, when described residual cache time during greater than congestion time threshold, can generate congested recovery feedback message, recover the unit or the module of message and can increase flow of high speed uplink grouping access service so that receive described congested feedback in the base station, augmented flow no longer after receiving above-mentioned congested feedback message according to this message.
As seen from the above, the method of the embodiment of the invention is by comparing with congestion time threshold value and congestion time threshold respectively in the residual cache time of base station side with the HSUPA service queue that gets access to, and, reduce the flow of described HSUPA business when described residual cache time during less than the congestion time threshold value; When described residual cache time during, increase the flow of described HSUPA business greater than congestion time threshold.Thereby, compared with prior art, the embodiment of the invention has been avoided in the prior art having improved the upstream bandwidth utilance of transmission link between base station controller and the base station according to adjusting the defective that response is untimely, bandwidth availability ratio is low that the HSUPA service traffics cause by the side of base station controller feedack.
In addition, for carrying out the method for the upstream bandwidth utilance of transmission link between described raising base station controller and the base station, can carry out that some are pre-configured in base station side.For example, can comprise:
(1) described congestion time threshold value and congestion time threshold are set.Wherein, described congestion time threshold value represents that the HSUPA service queue that sends is about to congested time threshold, and described congestion time threshold is represented that the flow with the HSUPA business is reduced to congested required time threshold is not taken place.These two values can rule of thumb be provided with arbitrarily.
(2) add sign for the formation that sends described high speed uplink chain grouping access service.As previously mentioned, though in the embodiment of the invention two described methods, be the formation that sends different business according to different priority.But, for increasing the flexibility that base station uplink signal is controlled, can be the HSUPA service queue in embodiments of the present invention and add queue identity, with convenient the flow of described HSUPA business is controlled.That is to say that before sending each professional formation, the base station can be determined that current queue is a high speed uplink chain grouping access service queue, and then carry out corresponding flow control according to queue identity.
(3) for described high speed uplink chain grouping access service queue linear queue number is set, and stores the linear queue number of described high speed uplink chain grouping access service and high speed uplink chain grouping access service user's corresponding relation.
Carrying out after this is provided with, portability is about to take place congested linear queue number and congested sign in the congested feedback message in above-mentioned steps 22, recovers can comprise in the message linear queue number and the congested recovery sign that needs augmented flow in congested feedback; Wherein said congested sign is used for expression and is about to take place flow congestion, need reduce the flow of HSUPA business, and congested recovery sign is used to represent the situation recovery of flow congestion, can increase the flow of HSUPA business.So, according to linear queue number and the above-mentioned stored relation in described congested feedback message or the congested feedback recovery message, just can reduce or increase the flow of the HSUPA business of relative users.
According to the description of above-mentioned method to the embodiment of the invention two, at the speech business flow hour, the HSUPA business can make full use of the remaining bandwidth of whole port; But be unlikely to simultaneously to allow base station controller find the professional frame losing of HSUPA again and just begun to reduce the transmitted traffic of HSUPA, but when the transmitted traffic of HSUPA is about to take the remaining bandwidth of whole port, adjust the transmitted traffic of HSUPA immediately, thereby reduce or avoided the professional frame losing phenomenon that occurs because transmitted traffic is too big of HSUPA.Simultaneously, when the speech business flow was big, the HSUPA business can be abdicated bandwidth again and give speech business.Therefore, the embodiment of the invention two described methods have improved the upstream bandwidth utilance of transmission link between base station controller and the base station.
