Below in conjunction with accompanying drawing the method and apparatus of realizing different-frequency measure according to the embodiment of the invention is provided description more specifically.
According to one embodiment of present invention, provide a kind of carrier selecting method.Fig. 1 illustrates the flow chart according to the carrier selecting method of this embodiment of the invention, and the method that present embodiment provides comprises following content.
S110, send the carrier wave precedence information to subscriber equipment, described subscriber equipment is measured carrier wave according to described carrier wave precedence information.
Specifically, existing under the professional situation between subscriber equipment and the base station, can send the carrier wave precedence information to subscriber equipment for the subscriber equipment serving base station.
Wherein, the base station can be determined the priority of each carrier wave of subscriber equipment when carrying out different-frequency measure by the SPID (Subscriber Profile ID, signatory Property ID) that subscriber equipment carries, and generates the carrier wave precedence information thus.
In one embodiment of the invention, RRC (Radio Resource Control can be passed through in the base station, Radio Resource control) any one in signaling, MAC CE (Medium Access Control Control Elements, media interviews control control element) and the broadcast sends to subscriber equipment with precedence information.
For example, the base station can send to subscriber equipment with precedence information by a RRC signaling.Perhaps, the base station also can send to subscriber equipment with precedence information by broadcast.
Subscriber equipment can come to carry out carrier wave at each carrier wave according to the carrier wave precedence information and measure.Specifically, subscriber equipment can be according to the order of measuring carrier wave priority, and the carrier wave that priority is the highest is measured as measuring carrier wave.
The measurement result that S120, reception subscriber equipment send is measurement report.
Specifically, the base station receives subscriber equipment according to the measurement result of carrier wave precedence information at the measurement carrier wave from subscriber equipment.
It is that subscriber equipment is selected carrier wave that the measurement result of S130, the measurement carrier wave that sends according to the described subscriber equipment that receives is come.
Specifically, the base station is the carrier wave that subscriber equipment selects to satisfy communication quality according to the requirement of subscriber equipment.
Thus, provide carrier selecting method according to the embodiment of the invention.In the method according to above-described embodiment, the base station can send the carrier wave precedence information to subscriber equipment, and subscriber equipment can be measured carrier wave according to the carrier wave precedence information.
But carrier selecting method described above is example only, the invention is not restricted to this, but can also carry out various remodeling.In another embodiment of the present invention, before the measurement result of the measurement carrier wave that receives the subscriber equipment transmission, described method can also comprise the step that sends the measurement threshold value to subscriber equipment.
Fig. 2 shows the flow chart according to the carrier selecting method of this embodiment.
S110 step among S210 step among Fig. 2, S230 step, S240 step and Fig. 1, S120 step, S130 step are similar, no longer give unnecessary details so that specification keeps succinct at this.
As shown in Figure 2, at step S220 place, the base station can send to subscriber equipment and measure threshold value.
Wherein, measuring threshold value can be the parameter that whether needs to measure next priority carrier wave after finishing for the measurement of judging current carrier wave (namely measuring carrier wave).Described measurement threshold value can be the parameter of any appropriate of expression channel quality, RSRP (Reference Signal Receiving Power among signal to noise ratio, the LTE for example, Reference Signal Received Power), RSRQ (Reference Signal Received Quality, Reference Signal Received Quality), noise, traffic rate etc. can characterize the parameter of channel quality, perhaps one or more combination of these parameters.
In one embodiment of the invention, can identical measurement threshold value be set for all carrier waves to be measured.In another embodiment of the present invention, also different measurement threshold values can be set at the carrier wave of different priorities, perhaps also can different measurement threshold values be set at the carrier wave of the different priorities of different communication systems, can realize thus judging more accurately.
Be used for judging the measurement threshold value that whether needs to measure next priority carrier wave after the measurement of current priority carrier wave finishes by sending to subscriber equipment, satisfy under the situation of measuring threshold value in measurement result, subscriber equipment can be reduced to the measurement number of times of lower priority carriers, the energy loss of subscriber equipment can be reduced thus.In addition, because subscriber equipment can report the base station rapidly with the measurement result that satisfies the high priority carrier wave of measuring threshold value, make the base station can make the operation of mobile management aspect rapidly, as switching etc., the so effective link between maintenance customer's equipment and the base station.
In said method, the base station can send to subscriber equipment with threshold value by various suitable manner.
In one embodiment of the invention, RRC (Radio Resource Control can be passed through in the base station, Radio Resource control) any one in signaling, MAC CE (Medium Access Control Control Elements, media interviews control control element) and the broadcast sends to subscriber equipment with the measurement threshold value.
In another embodiment of the present invention, the base station also can send to subscriber equipment with the measurement threshold value by the measurement configuration information that sends to the user in advance.Wherein, measurement configuration information can provide (for example by the RRC signaling) to give subscriber equipment in advance, can comprise in the measurement configuration information that carrier wave, measurement report that needs are measured trigger configuration etc.
For example, the base station can utilize the event threshold in the measurement report configuration in the measurement configuration information, will measure threshold value and send to subscriber equipment.
In a preferred exemplary, base station directly measurement report trigger event threshold value is set to the measurement threshold value that whether needs to measure next priority carrier wave after the current priority carrier wave measure to finish for judging.Like this, subscriber equipment can be directly threshold value by the measurement report trigger event obtain to measure threshold value.More particularly, subscriber equipment is after the measurement of finishing current carrier wave, the threshold value of measurement result and measurement report trigger event is compared, if measurement result is better than being arranged on the threshold value of the measurement report trigger event in the measurement report configuration, then judge and do not need to carry out the measurement of next priority carrier wave, otherwise, then judge and need carry out the measurement of the channel of lower priority carriers correspondence.
In another example, the base station can send to subscriber equipment with the measurement threshold value based on event threshold.Specifically, subscriber equipment can draw described measurement threshold value according to the event threshold in the measurement configuration information of base station transmission.For example, described measurement threshold value can be configured to 2 times of event threshold etc.And measure relation between threshold value and the event threshold (for example multiple relation etc.), can between base station and subscriber equipment, arrange in advance; Also can be handed down to subscriber equipment in advance by the base station.Thus, the base station can send to subscriber equipment with measuring threshold value.
Carrier wave method of measurement according to the embodiment of the invention described above is example only, the invention is not restricted to this, but can also carry out other various suitable remodeling.
For example, in another embodiment of the present invention, can also further send indication information to subscriber equipment, described indication information is used for (for example showing under the situation that need not continue to measure at next priority frequency in measurement result, measurement result is greater than the situation of measuring threshold value), the indication subscriber equipment continues to measure at one or more lower priority carriers.Thus, can avoid the disappearance of the measurement result of some important lower priority carriers, make the base station can obtain measurement result more comprehensively.
Fig. 3 shows the indicative flowchart of this embodiment.
Step S310 shown in Figure 3, S320, S340, S350 and step S210, S220, S230 and S240 shown in Figure 2 are similar.No longer give unnecessary details so that specification keeps succinct at this.
As shown in Figure 3, at step S330 place, the base station can send indication information to subscriber equipment, and described indication information is used for being better than under the situation of described measurement threshold value in the measurement result of measuring carrier wave, and the indication subscriber equipment continues to measure at the channel of one or more lower priority carriers correspondences.
It is to be noted, although in the embodiment shown in fig. 3, be used for being shown in to subscriber equipment to the step S330 that subscriber equipment sends indication information and send the step S310 of carrier wave precedence information and send after the step S320 that measures threshold value, but Fig. 3 is example only, the invention is not restricted to this.In fact, the step S320 to subscriber equipment transmission indication information also can carry out with the step S320 to subscriber equipment transmission carrier wave precedence information step S310 or transmission measurement threshold value or also can carry out before the step S320 of the step S310 that sends the carrier wave precedence information to subscriber equipment and transmission measurement threshold value simultaneously.
In one embodiment of the invention, can come to send indication information to subscriber equipment by in radio resource control RRC signaling, MAC CE and the broadcast any one or more.
In another embodiment of the present invention, also can send described indication information to the user by measurement configuration information.
In a concrete example, can send indication information to the user by the measuring object Measurement object in the measurement configuration information.
Specifically, for example shown in the Yi Xia code, can be indication information measObject SkipIndication of configuration among the measuring object Measurement object.This indication information measObject SkipIndication is used for the expression subscriber equipment after the channel that measures high priority carrier wave correspondence satisfies threshold requirement, whether continues to measure the channel of lower priority carriers correspondence.For example, measObject SkipIndication is configured to 1 expression to be continued to measure, and is configured to 0 expression and no longer continues to measure.In this way, can stop effectively flexibly or open subscriber equipment to the measurement of lower priority carriers respective channels.In addition, also as can be seen, the carrier wave precedence information also can dispose in Measurement object, for example can indicate with measObjectPriorityIndication in following code.The precedence information of the measuring object that the carrier wave precedence information is corresponding with this carrier wave is corresponding one by one.For example, the carrier wave precedence information is high, and then the precedence information of the measuring object of this carrier wave correspondence also is high.The carrier wave precedence information is low, and then the precedence information of the measuring object of this carrier wave correspondence also is low.
In another example, also can send indication information to the user by the measuring amount in the measurement configuration information.
Specifically, for example shown in following code, can in measuring amount measId, dispose an indication information measID SkipIndication.This indication information measIDSkipIndication is used for the expression subscriber equipment after the channel that measures high priority carrier wave correspondence satisfies the demands, for example, high priority carrier wave corresponding channel quality is higher than the event threshold value in the measurement report triggering configuration of measuring threshold value or measuring amount correspondence, whether continues to measure the channel of lower priority carriers correspondence.For example, measIDSkipIndication is configured to 1 expression to be continued to measure, and is configured to 0 expression and no longer continues to measure.In this way, can stop effectively flexibly or open subscriber equipment to the measurement of lower priority carriers.In addition, also as can be seen, the frequency precedence information also can dispose in measuring amount measId, as indicating with measIDPriorityIndication in following code.The precedence information of the measuring amount that the carrier wave precedence information is corresponding with this carrier wave is corresponding one by one.For example, the carrier wave precedence information is high, and then the precedence information of the measuring amount of this carrier wave correspondence also is high.The carrier wave precedence information is low, and then the precedence information of the measuring amount of this carrier wave correspondence also is low.
In the method for measuring according to the realization of above-described embodiment, whether base station configure user equipment is more flexibly measured at the low priority frequency, thereby, on the one hand, can save the energy that the measurement at each low priority frequency consumes, on the other hand, can avoid the disappearance of the measurement result of the interested low priority frequency in base station, make the base station can obtain measurement result more comprehensively.
Carrier selecting method according to above-described embodiment can realize that corresponding therewith, embodiments of the invention also provide can be in the carrier wave method of measurement of user equipment side realization in base station side.

Specifically, subscriber equipment can receive described carrier wave precedence information by in radio resource control RRC signaling, medium access control control element MAC CE and the broadcast one or more from the base station.
Wherein, described measurement threshold value can be used for judging the frequency that whether also needs to measure next priority after the current priority frequency measurement finishes.Described measurement threshold value can be can represent channel quality and with the corresponding parameter of described measurement threshold value, for example one or more combination in RSRP, RSRQ, the traffic rate among signal to noise ratio, the LTE.
Measuring threshold value can receive from the base station, also can be pre-arranged at the subscriber equipment place.
S420, the highest carrier wave of priority is made as the measurement carrier wave.
Specifically, subscriber equipment can be made as the measurement carrier wave according to the carrier wave precedence information carrier wave that priority is the highest.And at first this measurement carrier wave is measured.
If S430 measures the measurement result of carrier wave correspondence and is inferior to the measurement threshold value, then priority is lower than the highest carrier wave of the priority of measuring carrier wave as measuring carrier wave.
Specifically, priority can be lower than the highest carrier wave (being the carrier wave of next priority) of priority in the carrier wave of measuring carrier wave as the measurement carrier wave, and measure at this measurement carrier wave.
