In the embodiment of the present invention, average download rate when the amount of bandwidth adjustable strategies obtained in advance can use CA technology to download according to subscriber equipment and the ratio of flow downloading rate threshold value adjust, if average download rate when subscriber equipment uses CA technology to download is 2MB/s, flow speed of download threshold value is 1.5MB/s, when if subscriber equipment is downloaded use the sets of bandwidths of CA to be combined into 15M (main plot bandwidth)+10M+15M+20M, when performance element 303 is downloaded according to the amount of bandwidth adjustable strategies determination subscriber equipment obtained in advance use the bandwidth of CA combine in need the auxiliary bandwidth of cell quantity carrying out adjusting to be 1, the auxiliary component carrier wave bandwidth of CA being combined to 1 auxiliary bandwidth of cell (20M) correspondence in 3 the auxiliary bandwidth of cell comprised carries out deexcitation, this auxiliary bandwidth of cell (20M) is removed from the bandwidth combination of CA, activate auxiliary component carrier wave corresponding to 1 auxiliary bandwidth of cell (5M) simultaneously, auxiliary bandwidth of cell (5M) corresponding for the auxiliary component carrier wave activated is added the bandwidth combination of CA, the sets of bandwidths of the CA after being adjusted is combined into 15M (main plot bandwidth)+10M+15M+5M, implement the embodiment of the present invention, one or more auxiliary bandwidth of cell in directly the bandwidth of CA being combined is removed, activate the auxiliary component carrier wave equal with this one or more auxiliary bandwidth of cell quantity simultaneously, can effectively control subscriber equipment downloading rate, save UE flow.
In the embodiment of the present invention, receiving element 301 receives the flow downloading rate threshold value that subscriber equipment sends; Whether average download rate when judging unit 302 judges that subscriber equipment uses CA technology to download is greater than flow downloading rate threshold value; When judging unit 302 judged result is for being, when subscriber equipment is downloaded by performance element 303 use the bandwidth of CA to combine bandwidth reduce, be less than or equal to flow downloading rate threshold value to make subscriber equipment average download rate.Implement the embodiment of the present invention, by the bandwidth combination of adjustment CA to adjust subscriber equipment average download rate, for the subscriber equipment of underfed, can effectively can control subscriber equipment downloading rate, save UE flow.
Refer to Fig. 4, Fig. 4 is the structural representation of another kind of base station disclosed in the embodiment of the present invention.As shown in Figure 4, the base station described in the present embodiment, except comprising the receiving element 301 shown in Fig. 3, judging unit 302 and performance element 303, also comprises transmitting element 304, wherein:
Transmitting element 304, for sending the configuration information of the flow downloading rate comprising measurement subscriber equipment to make the flow downloading rate of user's device measuring subscriber equipment to subscriber equipment; Wherein, when the flow downloading rate of subscriber equipment exceedes predetermined threshold value, subscriber equipment prompting user arranges flow downloading rate threshold value.
In the embodiment of the present invention, when subscriber equipment receive transmitting element 304 send comprise measure subscriber equipment flow downloading rate configuration information after, the flow downloading rate of subscriber equipment measured by subscriber equipment, predetermined threshold value can set according to the flow package of subscriber equipment customization, the total flow that flow package comprises is more, predetermined threshold value is larger, when the flow downloading rate of subscriber equipment exceedes predetermined threshold value, subscriber equipment prompting user arranges flow downloading rate threshold value, implement the embodiment of the present invention, flow downloading rate threshold value can be set reminding user, facilitate the flow service condition of the real-time supervisory user equipment of user, improve Consumer's Experience.
In the embodiment of the present invention, transmitting element 304 sends the configuration information of the flow downloading rate comprising measurement subscriber equipment to make the flow downloading rate of user's device measuring subscriber equipment to subscriber equipment; Receiving element 301 receives the flow downloading rate threshold value that subscriber equipment sends; Whether average download rate when judging unit 302 judges that subscriber equipment uses CA technology to download is greater than flow downloading rate threshold value; When judging unit 302 judged result is for being, when subscriber equipment is downloaded by performance element 303 use the bandwidth of CA to combine bandwidth reduce, be less than or equal to flow downloading rate threshold value to make subscriber equipment average download rate.Implement the embodiment of the present invention, by the bandwidth combination of adjustment CA to adjust subscriber equipment average download rate, for the subscriber equipment of underfed, can effectively can control subscriber equipment downloading rate, save UE flow.
Refer to Fig. 5, Fig. 5 is a kind of system schematic controlling carrier aggregation CA downloading rate disclosed in the embodiment of the present invention, a kind of shown in Fig. 5 controls the system of carrier aggregation CA downloading rate for performing the method controlling carrier aggregation CA downloading rate disclosed in the embodiment of the present invention, as shown in Figure 5, the system of this control carrier aggregation CA downloading rate can comprise:
Base station 50 and subscriber equipment 51, wherein, base station 50 is connected by wireless network with subscriber equipment 51;
Subscriber equipment 51, for base station 50 transmitted traffic downloading rate threshold value;
Base station 50, whether average download rate during for judging that subscriber equipment uses CA technology to download is greater than flow downloading rate threshold value; When if so, subscriber equipment being downloaded use the bandwidth of CA to combine bandwidth reduce, be less than or equal to flow downloading rate threshold value to make subscriber equipment average download rate.
Visible, by the system of the control carrier aggregation CA downloading rate described by Fig. 5, effectively can control subscriber equipment 51 downloading rate, save the flow of subscriber equipment 51.One of ordinary skill in the art will appreciate that all or part of step in the various methods of above-described embodiment is that the hardware that can carry out instruction relevant by program has come, this program can be stored in a computer-readable recording medium, storage medium can comprise: flash disk, read-only memory (Read-OnlyMemory, ROM), random access device (RandomAccessMemory, RAM), disk or CD etc.
Above to the embodiment of the present invention provide a kind of control carrier aggregation CA downloading rate method and base station be described in detail, apply specific case herein to set forth principle of the present invention and execution mode, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
