Above-mentioned base station can also comprise: the whole control device of Iub resource, and be used to detect described base station and whether take place whole congestedly, and testing result offered the scheduler device.
Whether the whole control device of described Iub resource detects described base station and takes place whole congested according to the transmission carrying congestion indication about portable terminal that described volume control device obtains.
Following accompanying drawing is described in detail most preferred embodiment of the present invention.
Fig. 1 is the processing procedure schematic diagram of a kind of Iub interface transmission carrying congestion of the embodiment of the invention.
As shown in Figure 1, base station 10 can comprise scheduler device 101, volume control device 102, the whole control device 103 of Iub resource, data buffer zone 104, Frame Protocol processing unit 105 and Deplexing apparatus 106, and radio network controller 20 can comprise transmission carrying congestion checkout gear 201 and Frame Protocol processing unit 202.Here need to prove that data buffer zone 104 can be the data buffer zone of an integral body, that is, all send the portable terminal of upstream datas can corresponding data buffering area, but these data buffer zones all are the parts of data buffer zone 104.In general, data buffer zone 104 can also keep a part of space as motor-driven use, for example, when the data buffer zone of certain portable terminal correspondence need increase heap(ed) capacity, data buffer zone 104 can be increased to all or part of space in this part space of keeping the data buffer zone of this portable terminal correspondence.In addition, Deplexing apparatus 106 can be converted to wireless signal the data that 10 inside, base station can be discerned and transmit, and also the data that 10 inside, base station can be discerned and transmit can be converted to wireless signal.
In Fig. 1, when transmission carrying congestion checkout gear 201 detects Iub interface the transmission carrying congestion of certain portable terminal takes place, transmission carrying congestion checkout gear 201 can send the transmission carrying congestion indication of certain portable terminal to volume control device 102, the content of described indication for example comprises that data packet transmission postpones or data packet transmission is lost, after volume control device 102 is received this indication, have three kinds of subsequent operation modes at least:
First kind of mode: volume control device 102 is adjusted the maximum storage capacity of the data buffer zone 104 of described portable terminal correspondence.In general, when the transmission carrying congestion of described portable terminal took place Iub interface, volume control device 102 can increase the maximum storage capacity of the data buffer zone of described portable terminal correspondence.During specific implementation, volume control device 102 can send control information to the data buffer zone of described portable terminal correspondence, described control information requires the data buffer zone of described portable terminal correspondence to increase the maximum storage capacity of self, to keep in the data that more described portable terminal sends, after control information is received in the data buffer zone of described portable terminal correspondence, just can increase the maximum storage capacity of self according to the requirement of control information.Further, when volume control device 102 requires the data buffer zone of described portable terminal correspondence to increase the maximum storage capacity of self, the degree of the maximum storage capacity after can also specifying the data buffer zone of described portable terminal correspondence to increase, for example, with MB is certain numerical value of unit, certainly, volume control device 102 can only require that also the data buffer zone of described portable terminal correspondence increases the maximum storage capacity of self, being increased to what degree can not specify, but is determined voluntarily according to actual conditions by the data buffer zone of described portable terminal correspondence.Because the data that a large amount of described portable terminals sends can be kept in base station 10, so the data that base station 10 will be not too much are dealt into radio network controller 20 by Iub interface, thereby alleviated even solved fully the transmission carrying congestion of the described portable terminal of Iub interface generation, simultaneously, also avoided generation owing to the less loss of data phenomenon that causes of maximum storage capacity of the data buffer zone of described portable terminal correspondence as far as possible.
The second way: volume control device 102 passes to scheduler device 101 with the transmission carrying congestion indication of described portable terminal, and subsequent treatment is by 101 decisions of scheduler device.In addition, volume control device 102 can be handled accordingly according to the decision or the indication of scheduler device 101.For example, scheduler device 101 can require volume control device 102 to increase the maximum storage capacity of the data buffer zone of described portable terminal correspondence, further, can specify the degree of increase, volume control device 102 is according to the requirement of scheduler device 101, increase the maximum storage capacity of the data buffer zone of described portable terminal correspondence, perhaps the maximum storage capacity of the data buffer zone of described portable terminal correspondence is increased to the degree of appointment.
The third mode: volume control device 102 had both been adjusted the maximum storage capacity of the data buffer zone of described portable terminal correspondence, and the transmission carrying congestion indication with described portable terminal passes to scheduler device 101 again.
In addition, when transmission carrying congestion checkout gear 201 detects the transmission bearer of described portable terminal of Iub interface when no longer congested, transmission carrying congestion checkout gear 201 can send the no longer congested indication of transmission bearer of described portable terminal to volume control device 102, after volume control device 102 is received this indication, the data buffer zone that can reduce described portable terminal correspondence is through adjusted maximum storage capacity, for example, the maximum storage capacity with the data buffer zone of described portable terminal correspondence returns to original capacity.
Volume control device 102 can also be used for data buffering area 104 is detected, and for example, whether whether the data buffer zone of detecting certain portable terminal, some portable terminal or all portable terminal correspondences near saturated or saturated etc.If the data buffer zone of certain portable terminal correspondence is near saturated or saturated, illustrate that then there has been the potential transmission carrying congestion of described portable terminal in Iub interface, at this moment, volume control device 102 can send the potential transmission carrying congestion indication that there has been described portable terminal in Iub interface to scheduler device 101.Volume control device 102 also can be adjusted the maximum storage capacity of the data buffer zone of described portable terminal correspondence voluntarily, perhaps adjusts the maximum storage capacity of the data buffer zone of described portable terminal according to the indication of scheduler device 101.In addition, when the potential transmission carrying congestion that detects the unborn described portable terminal of Iub interface when volume control device 102 disappears, the data buffer zone that can reduce described portable terminal correspondence is through adjusted maximum storage capacity, for example, the maximum storage capacity with the data buffer zone of described portable terminal correspondence returns to original capacity.Concrete, a capacity thresholding can be set for the data buffer zone of portable terminal correspondence, if the data buffer capacity that volume control device 102 detects the portable terminal correspondence has surpassed or has equaled the capacity thresholding, can determine that then there has been the potential transmission carrying congestion of described portable terminal in Iub interface, otherwise, can determine that there is not the potential transmission carrying congestion of described portable terminal in Iub interface, can determine that perhaps the potential transmission carrying congestion of unborn described portable terminal disappears.Further, volume control device 102 can regularly detect the capacity of data buffer zone 104, with the data buffer capacity of definite portable terminal correspondence and the magnitude relationship between the capacity thresholding.Wherein, the data buffer capacity of portable terminal correspondence can be an absolute figure (for example unit is the numerical value of byte or bit), and at this moment, the capacity thresholding also is an absolute figure; The data buffer capacity of portable terminal correspondence also can be a percentage (for example percentage of the capacity of current use and heap(ed) capacity), and at this moment, the capacity thresholding also is a percentage.
In addition, volume control device 102 can also represent that whole congested whole congested indication has taken place in base station 10 according to the whole control device 103 of Iub resource being used to of sending, and adjusts the heap(ed) capacity of the data buffer zone of the whole volume of data buffer zone 104 or each portable terminal correspondence.Certainly, receive the indication of whole congestion cleared when volume control device 102 after, also can adjust the heap(ed) capacity of the data buffer zone of the whole volume of data buffer zone 104 or each portable terminal correspondence.Further, after volume control device 102 is received the whole congested indication that the whole control device 103 of Iub resource sends, can be according to the operating position of the data buffer zone of each current portable terminal correspondence, determine whether to take place the potential congestion of certain or some portable terminals, if the data buffer zone of this or these portable terminal correspondence is then adjusted in the generation potential congestion.
The process of the maximum storage capacity of the data buffer zone of volume control device 102 certain portable terminal correspondence of adjustment is shown in Fig. 2 A and Fig. 2 B, in Fig. 2 A and Fig. 2 B, volume control device 102 has increased subscriber equipment (UE, User Equipment) heap(ed) capacity of the data buffer zone of 1 correspondence, that part of memory capacity of increase are a part of capacity that keeps in the buffering area.
After scheduler device 101 is received the transmission carrying congestion indication of certain portable terminal that volume control device 102 sends, need make corresponding operation, its objective is the data that will reduce uplink as early as possible, to avoid the further congested of upstream data, guarantee that upstream data do not lose or do not postpone, certainly, at different congestion type, scheduler device 101 can be taked different means.Concrete, as shown in Figure 3, comprising:
Step S301: the transmission carrying congestion indication of certain portable terminal that reception volume control device 102 sends.In fact, the congested indication that volume control device 102 sends is exactly that transmission carrying congestion checkout gear 201 in the radio network controller 20 sends, certainly, if necessary, the form of the volume control device 102 congested indication of sending can be different from the form of the congested indication that transmission carrying congestion checkout gear 201 sends.
Step S302 a: sign is set, is used to forbid sending the order that promotes resource to described portable terminal.In general, if send the order that promotes resource to certain portable terminal, then coming down to provides more resources in order to send more upstream data to this portable terminal.Owing in step S301, received the transmission carrying congestion indication, so, here require not send the order that promotes resource, and then avoid providing more resources in order to sending more upstream data to described portable terminal to described portable terminal, thus the alleviate congestion degree.
Step S303: start the timer of forbidding promoting resource.Scheduler device 101 can be separately for forbidding that promoting resource is provided with a timer, a general timer also can be set, when scheduler device 101 need use timer for specific purpose, general timer was exactly the timer with specific purpose.The timing of timer can be decided according to the actual requirements.
Step S304: check the content of transmission carrying congestion indication, postpone, then change step S305,, then change step S306 if the content of transmission carrying congestion indication is that data packet transmission is lost if the content of transmission carrying congestion indication is a data packet transmission.
Step S305: improve the dispatching priority of described portable terminal in scheduling queue.
Step S306: reduce the dispatching priority of described portable terminal in scheduling queue, and decision sends the order of forbidding promoting resource or reducing resource to described portable terminal.Concrete, if the data-bag lost of receiving indication number of times then sends the order of forbidding promoting resource to described portable terminal more than or equal to configured threshold; If the data-bag lost of receiving indication number of times then sends the order that reduces resource to described portable terminal less than configured threshold.
In addition, the potential transmission carrying congestion indication of certain portable terminal that scheduler device 101 can also send according to volume control device 102 is handled accordingly.For example, scheduler device 101 can not identify and send the order that promotes resource to described portable terminal after receiving the potential transmission carrying congestion indication of certain portable terminal that volume control device 102 sends; When scheduler device 101 determines that the potential transmission carrying congestion of described portable terminal has not existed, a sign is set, is used for sending the order that promotes resource to described portable terminal.Concrete, if the data buffer capacity that volume control device 102 detects the portable terminal correspondence has surpassed or has equaled the capacity thresholding, then can send the potential transmission carrying congestion indication of described portable terminal to scheduler device 101, scheduler device 101 can not identify and send the order that promotes resource to described portable terminal according to this indication; If detecting the data buffer capacity of portable terminal correspondence, volume control device 102 has been lower than the capacity thresholding, then can send the indication that the potential transmission carrying congestion of described portable terminal has disappeared to scheduler device 101, scheduler device 101 is according to this indication, and sign can send the order that promotes resource to described portable terminal.
Need to prove for whether scheduler device 101 signs send the order that promotes resource to described portable terminal a timer to be set, this timer is called forbids that resource promotes timer here.Concrete, when scheduler device 101 signs are forbidden when described portable terminal sends the order that promotes resource, start and forbid that resource promotes timer, when timing arrived, scheduler device 101 signs can send the order that promotes resource to described portable terminal.Further, when timing arrives, can also judge whether to receive new congestion information, if do not have, then scheduler device 101 signs can send the order that promotes resource to described portable terminal, otherwise scheduler device 101 still identifies to be forbidden sending the order that promotes resource to described portable terminal, even perhaps sign forbids sending the order that promotes resource to described portable terminal, also to order described portable terminal to ban use of the resource of lifting.
In Fig. 1, the whole control device 103 of Iub resource is used for the Iub resource is carried out integral body control.Concrete, whether the whole control device 103 of Iub resource can base stations detected 10 takes place whole congestedly, and the result who detects can be offered scheduler device 101.The whole control device 103 of Iub resource can also receive the transmission carrying congestion indication of certain portable terminal that volume control device 102 sends, and handles accordingly according to this indication.For example, the whole control device 103 of Iub resource can be indicated according to this, perhaps adds other indexs, and it is whole congested to judge whether base station 10 takes place.
In Fig. 1, the Frame Protocol processing unit 105 of base station 10 and the Frame Protocol processing unit 202 of radio network controller 20 are used for the processed frame agreement.Send data instance with base station 10 to radio network controller 20, the format conversion that Frame Protocol processing unit 105 can send to base station 10 data of radio network controller 20 is the Iub interface form, the data of the Iub interface form after will changing afterwards offer Frame Protocol processing unit 202, and Frame Protocol processing unit 202 is converted to other devices of radio network controller 20 or the form that functional unit can be discerned with the data of Iub interface form again.
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.
