Embodiment
The embodiment of the invention provides a kind of load control method and device, in order to the carrier load balance of realization carrier aggregation system, thereby avoids the too high problem of the carrier load of problem in the carrier aggregation system, improves resource utilization.
The embodiment of the invention is considered the problem of LTE Release 8 compatibilities, and in conjunction with the characteristics of carrier aggregation system, both consider the expense/factors such as time-delay of user terminal (UE) power consumption and scheduling of resource simultaneously, provided a kind of carrier load balance technical scheme that is applicable in the carrier aggregation system.
The described carrier aggregation system of the embodiment of the invention can be a LTE-A system etc.
The so-called carrier load balance of the embodiment of the invention, can be understood as in carrier aggregation system, with the UE that carries on one or more member carriers, share equally on other member carriers, make that the load occupation proportion of each member carrier is suitable, thereby the phenomenon that the load of avoiding single member carrier is overweight improves resource utilization.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 2, a kind of load control method that the embodiment of the invention provides totally comprises step:
S101, the member carrier in the carrier aggregation system is carried out real-time load monitoring, obtain the load monitoring result of member carrier.
S102, according to the load monitoring result of the member carrier in the carrier aggregation system, adjust the load of the member carrier in this carrier aggregation system.
Load control can be realized by the base station.The base station is to being measured and added up by the loading condition of the member carrier that UE caused that is in Radio Resource control (RRC, Radio Resource Control) connection status on each member carrier in the carrier aggregation system.Particularly, be in the number of the UE of RRC connection status, the type of service of UE and the resource that UE takies etc. on bandwidth that can be by measuring and add up each member carrier, each member carrier, obtain the load monitoring result of each member carrier.
The load monitoring result of member carrier can comprise the load occupation proportion of member carrier, and the load that each terminal takies on this member carrier etc.The load occupation proportion of so-called member carrier, i.e. the ratio of the total bandwidth of the shared total load of all terminal traffics of carrying on member's carrier wave and this member carrier.
For example: the business of an IP-based voice transfer (VoIP, Voice over IP) is compared with the business of a Streaming Media, and the VoIP business is little more than the load that streaming media service brings for the load that member carrier brings.
Again for example: for the bandwidth of a member carrier is that the bandwidth of a 20MHz and a member carrier is 5MHz, identical business and terminal, and the load occupation proportion that these two member carriers are caused is different.
The load monitoring result of member carrier has application widely, for example: the foundation that can be used as the intercarrier load-balancing algorithm; Can be used as system control information and broadcast, make UE when Cell searching, select suitable resident carrier wave; The load monitoring result of member carrier can be mapped as the attraction degree factor of this member carrier to UE, this attraction degree factor can be used as system control information and broadcasts, and makes UE select suitable resident carrier wave when Cell searching; After the UE random access procedure is finished, but be not attended by under the professional situation about taking place, can UE be carried out intercarrier switch according to the load monitoring result of member carrier.
Described step S102 is according to the load monitoring result of the member carrier in the carrier aggregation system, the operation of adjusting the load of the member carrier in this carrier aggregation system can be that initiatively carry out the base station, also can be after receiving the carrier wave handoff request of terminal, carry out according to the carrier wave handoff request of this terminal.
The concrete implementation of adjusting the load of member carrier can have multiple.
For example: according to the load occupation proportion of each member carrier in the carrier aggregation system, and the load that each terminal takies on this member carrier, according to the load occupation proportion difference threshold that sets in advance, adjust the load of the member carrier in the carrier aggregation system.Wherein, setting in advance the purpose of described load occupation proportion difference threshold, is in order to make the load occupation proportion of adjusted each member carrier of load suitable, to differ as far as possible little, to reach the load balancing of each member carrier.
Again for example: the load monitoring result and the load-threshold that sets in advance of member carrier are compared; Utilize comparative result to adjust the load of member carrier.Wherein, the different members carrier wave can corresponding different load-threshold, with the load monitoring result of member carrier and comparing with the corresponding load-threshold of this member carrier of setting in advance.Certainly, the different members carrier wave also can corresponding same load-threshold.
Preferably, when the load monitoring result of member's carrier wave surpasses the load-threshold that sets in advance, adjust the load of member carrier.
Preferably, when the load monitoring result of member's carrier wave surpasses the load-threshold that sets in advance, the business of the one or more terminals on this member carrier is switched on another member carrier.
And preferably, switch to the business of the one or more terminals on the member carrier on another member carrier after, according to the load seizure condition difference threshold that sets in advance, further adjust the load of the member carrier in the carrier aggregation system.Described load seizure condition difference threshold can be the difference threshold of the load occupation proportion of each member carrier, also can be the difference threshold of the load of each member carrier.
Wherein, employed thresholding in the step that the load monitoring result of member carrier and the load-threshold that sets in advance are compared can be according to the difference of the load monitoring result's of member carrier content, and the thresholding of different content is set.If the load monitoring result of member carrier comprises the load occupation proportion of member carrier, then corresponding thresholding can be set to load occupation proportion thresholding.If the load monitoring result of member carrier comprises the number of the user terminal that carries on the member carrier, then corresponding thresholding can be set to the number thresholding of user terminal.The thresholding of other guide can also have a lot, for example radio network temporary identifier (RNTI, Radio Network Temporary Identity) number or the like.
When the member carrier in the carrier aggregation system being carried out the load adjustment, the factor that needs to consider has a lot, for example: the type of the RNTI number of the load of each UE in the carrier aggregation system on each member carrier, UE, the business of UE, resource that each different kinds of business takies or the like illustrate below.
Suppose to have in the carrier aggregation system 4 member carriers, all member carriers have identical bandwidth, and the load-threshold of member carrier also is identical.Before load is adjusted the loading condition of each member carrier as shown in Figure 3, wherein UE1, UE2, UE3, UE4, UE5, UE6 are the loads that exists on member carrier separately, the load that each UE causes is different.UE7 enters the RRC state on member carrier 1.At this moment, at first,, determine that UE7 is the load state that member carrier 1 brings, and calculate the load of current each member carrier according to the state of affairs of UE7.As shown in Figure 3, original load of member carrier 1 and the load sum of UE7 are greater than the member carrier load-threshold, then trigger the load balancing operation between member carrier, if the load sum of original load of member carrier 1 and UE7 does not surpass the member carrier load-threshold, then UE7 can directly insert member carrier 1.
When the load balancing operation that has triggered between member carrier, adopt the water-filling algorithm of iteration, pay the utmost attention to load balancing,, select optimum member carrier as the purpose carrier wave that switches to the water-filling algorithm that carries out on each member carrier one by one that loads on of UE7 to the UE7 of new access.As can be seen from Figure 3, the load minimum that member carrier 2 is current, therefore, the purpose carrier wave of selecting member carrier 2 to switch as UE7.The loading condition of each member carrier after the switching as shown in Figure 4.
Further, after the member carrier that has switched the UE7 access, also can carry out member's intercarrier load balancing, make that the load occupation proportion of each member carrier is further average other UE that has existed.
Below the carrier wave handover mechanism that provides in the embodiment of the invention is described.
The base station is at the target member carrier of having determined terminal is switched to after need carrying out the terminal of member's intercarrier switching, and the base station sends to this terminal carries out the indication information that member's intercarrier switches.
Described indication information can send by the high level control signaling of RRC, switches on the target member carrier by the to be switched terminal of the mutual indication of high-level signaling.
The retardation ratio of the control signaling of layer 1 (L1)/layer 2 (L2) is less, therefore described indication information also can send by the control signaling of L1/L2, the to be switched terminal of control signaling indication by L1/L2 switches on the target member carrier, particularly, can be by the target member carrier of indication switching in sending to the descending control signaling of this terminal.For example: in the LTE system, can be by down link control information (DCI at packet data control channel (PDCCH), Downlink control information) increases the specific bit of the target member carrier be used to indicate switching in the indication, can stipulate if this specific bit is set to NULL, represent that then indicating terminal resides on the current member carrier, in the transmission of the enterprising industry affair of current carrier wave; Can also stipulate that terminal need switch on the target member carrier according to this specially indication of bit among the DCI so if specific bit in the DCI form is provided with the information of the target member carrier of switching.
Insert member carrier and the professional process that takes place below in conjunction with terminal, the embodiment of the invention is described.
Terminal in the process of Cell searching, from all member carriers of system at random/acquiescence member carrier of selection as main carrier; Perhaps according to the loading condition of the member carrier in the current broadcast message, perhaps the carrier wave attracting factor selects a member carrier as main carrier after taking all factors into consideration.Then, terminal resides on this main carrier, only monitors the information of main carrier.
When terminal is in idle condition, monitor control messages by main carrier, comprising system message, broadcast control message, beep-page message etc.The random access procedure of terminal etc. all is to carry out on main carrier.
After terminal enters the RRC connection status, if also there be not professional the generation, then can initiatively send the carrier wave handoff request according to loading condition according to the member carrier in the broadcast to the base station, i.e. request switches to another member carrier with current main carrier.After the carrier wave handoff request of terminal transmission was received in the base station, according to the load of current each member carrier, decision switched to terminal on the lightest member carrier of load.
After terminal entered the RRC connection status, if there is business (up and/or downlink business) to take place, base station side judged whether to carry out the load balancing operation of member's intercarrier, and if desired, then base station side is carried out the load balancing control procedure between member carrier.
For example, as shown in Figure 5, suppose that carrier aggregation system has only 3 member carriers, is respectively: member carrier 1, member carrier 2, member carrier 3.The terminal that is in free time (IDLE) state has 5, all resides on the member carrier 2.
Can adopt the load as member carrier of the number of terminals that is in the RRC connection status, certainly, corresponding load-threshold also is a terminal number, for example can be made as 3.
When terminal is in idle condition, only monitor the control information of main carrier.Member carrier 2 is main carriers of UE1, UE2, UE3, UE4 and UE5.
When UE1, UE2, UE3, UE4, UE5 entered the RRC connection status by main carrier, the load of member carrier 2 had surpassed load-threshold, triggered the load balancing control procedure between member carrier.
Load balancing control procedure between concrete member carrier comprises: according to the load state of each member carrier, the load-threshold of member carrier and the state of affairs of each terminal, optimize and need carry out terminal and the corresponding target member carrier that switches that carrier wave switches.Suppose that the terminal that optimizes is UE2 and UE4, corresponding target member carrier is a member carrier 1; The terminal that optimizes also has UE5, and corresponding target member carrier is a member carrier 3, and UE1 and UE3 still are retained on the member carrier 2.
By RRC high-level signaling or L1/L2 control signaling UE2 and UE4 are switched on the member carrier 1, UE5 is switched on the member carrier 3.
Further, the base station continues the loading condition of each member carrier is added up.
When UE6, UE7, UE8 entered the RRC connection status by member carrier 2, the number of the terminal on the member carrier 2 had surpassed the carrier load thresholding so, needed to trigger the load balancing control procedure between member carrier.Suppose that this process switches to terminal UE 3 and UE8 on the member carrier 3, UE1, UE6 and UE7 still are retained on the member carrier 2, and UE2 and UE4 still are retained on the member carrier 1.
When terminal when the RRC connection status is got back to idle condition, UE still resides in and withdraws from the RRC connection status member carrier before, at this moment the main carrier of UE1, UE6, UE7 is a member carrier 2, the main carrier of UE2, UE4 is a member carrier 1, and the main carrier of UE3, UE5, UE8 is a member carrier 3.
