Embodiment
How the embodiment of the present invention is the problem that terminal distribution random access resource does not also have concrete scheme for target eNB in prior art, proposition is when terminal has switching demand, by source eNB, determine terminal with respect to the switching priority of other-end and send to target eNB, by target eNB according to the switching priority of terminal, dispatch corresponding access-in resource to terminal, wherein the switching priority of terminal is higher, scheduling to the access-in resource of terminal in time domain more forward and/or scheduling to the higher technical scheme of access success rate of the access-in resource of terminal, wherein the access success rate of access-in resource refers to that terminal used number of times that this access-in resource successfully accesses and this access-in resource to be scheduled to the ratio of the total degree of terminal.By implementing the technical scheme of the embodiment of the present invention, the switching priority that can realize terminal is higher, more can be by priority scheduling to good access-in resource, thereby the terminal that has guaranteed high switching priority can preferentially complete switching, guarantee preferably carrying out smoothly of communication service, and to terminal scheduling random access resource, provide concrete technical scheme for target eNB.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, in the scheduling of resource process that in the embodiment of the present invention, terminal is switched between base station, the processing procedure of source base station is as follows:
The measurement report that the terminal UE that step 101, source base station reception will initiate to switch between base station is sent;
Preferably, in step 103, source base station determines that the switching priority of the UE that will initiate switching between base station can be, but not limited to three kinds of modes, and hypothesis UE being had to height below, neutralizing low three switching priority is that example is come to three kinds, to determine that the modes of switching priority are specifically introduced respectively.
Mode one, source base station are according to the service quality QoS of the current communication service of UE, determine the switching priority of UE, be specially: can preset according to different application scenarios two QoS threshold values, i.e. a QoS threshold value QoS1 and the 2nd QoS threshold value QoS2, wherein Qos1 is less than Qos2.When if the QoS of the current communication service of UE is less than QoS1, source base station determines that the switching priority of UE is low switching priority; When if the QoS of the current communication service of UE is greater than QoS1 and is less than QoS2, source base station determines that the switching priority of UE is middle switching priority; When if the QoS of the current communication service of terminal is greater than QoS2, source base station determines that the switching priority of UE is the high priority of switching.
Mode two, source base station are determined the switching priority of the UE that will initiate switching between base station according to the type of service of the current communication service of UE, be specially: if UE is current need to maintain voice and/or video call service time, source base station determines that the switching priority of UE is the high priority of switching; If UE is current, need to maintain internet data business, source base station determines that the switching priority of UE is middle switching priority; If UE is current, only needs to maintain Radio Resource control connection RRC-CONNECTD state and do not carry out any communication service, source base station determines that the switching priority of UE is low switching priority.
Whether mode three, source base station are access networks first according to UE, determine the switching priority of the UE that will initiate switching between base station, are specially: if UE is access network first, source base station determines that the switching priority of UE is low switching priority; If UE right and wrong are access network first, source base station determines that the switching priority of UE is the high priority of switching; Wherein, non-access network first accessed network but all failures of access before referring to UE, and this access is access again.
In the embodiment of the present invention, can list with the form of list the switching priority of terminal, also can show by the form that other can show terminal switching priority orders.The terminal switching priority of following table 1 for listing with the form of list:
Table 1
In above-mentioned specific embodiment, that switching priority with UE is divided into high, medium and low three and switches priority and be described, certainly according to concrete application scenarios and implementation environment, also can be divided into high and low two priority levels by switching priority, or can also be divided into the highest, inferior high, in, inferior low and minimum five switch priority, being specifically divided into several switching priority can determine according to application demand.
Instruction is confirmed in the switching that step 105, the follow-up receiving target of source base station base station are returned;
After step 106, source base station receive and switch confirmation instruction, the UE that indication will be initiated to switch between base station switches to target BS.
As shown in Figure 2, in the scheduling of resource process that in the embodiment of the present invention, terminal is switched between base station, the processing procedure of target BS is as follows:
The switching related signaling that send step 201, target BS reception sources base station;
Step 202, target BS switch and confirm instruction to source base station feedback;
Step 203, target BS, from the switching related signaling receiving, are determined the switching precedence information of the UE that will initiate switching between base station of its carrying;
Step 204, target BS, according to the above-mentioned switching priority of determining, are the UE scheduling access-in resource that will initiate to switch between base station;
Fig. 3 has provided the schematic diagram directly perceived that different scheduling resources distribute at time-domain and frequency-domain, as shown in Figure 3, transverse axis is time shaft (expression time domain), the longitudinal axis is frequency axis (expression frequency domain), the intersection point of different time domain and frequency domain just there will be different access-in resources so, be that each access-in resource refers to a running time-frequency resource, in Fig. 3, each stain signal is exactly different running time-frequency resources, each running time-frequency resource represents an access-in resource, each access-in resource is dispatched to after UE, UE just can be used corresponding frequency resource access network at corresponding time point according to this access-in resource.
Preferably, in step 203, target BS can be, but not limited to three kinds of modes according to the switching priority of UE to UE scheduling access-in resource, supposes that UE has height, neutralizes low three switching priority is that example is come respectively three kinds of scheduling modes to be specifically introduced below.And then according to application scenario, can on the basis of Fig. 3, preset two time domain threshold value: T1 and T2 here, and wherein T1 is prior to T2, and T1 time point is front, after T2 time point leans on.
Mode one, according to the switching priority of UE and the time order and function of access-in resource that can be used for scheduling, carry out the scheduling of access-in resource.Be specially: if the switching priority of UE is the high priority of switching, be UE scheduling access-in resource before T1 in time domain, in Fig. 3,12 of the T1 left side access-in resources all can be dispatched the UE that switches priority to height; If the switching priority of UE is middle switching priority, be UE scheduling access-in resource between T1 and T2 in time domain, in Fig. 3,18 access-in resources on the T1 right side to the T2 left side all can be dispatched the UE to middle switching priority; If the switching priority of UE is low switching priority, be the access-in resource of UE scheduling after T2, in Fig. 3,12 of the T2 right side access-in resources all can be dispatched the UE to low switching priority.
Wherein the quantity of predefined time domain threshold value can be determined according to the rank number of switching priority, if be set with N, switches priority level, needs to preset N-1 time domain threshold value.
In the concrete enforcement of the present invention, when networking, can in target BS, configure the time order and function of access-in resource in the time domain order that can be used for scheduling, determine which access-in resource in time domain between 0 ~ T1, which access-in resource in time domain between T1 ~ T2, which access-in resource in time domain after T2.
Mode two, according to the switching priority of UE and the access success rate of access-in resource that can be used for scheduling, carry out the scheduling of access-in resource.Be specially; Can according to application scenario, set two access success rate threshold values in advance: the first access success rate threshold value A and the second access success rate threshold value B, wherein threshold value A is less than threshold value B.Wherein the access success rate of access-in resource refers to that UE is used number of times that this access-in resource successfully accesses and this access-in resource to be scheduled to the ratio of the total degree of UE, such as for some access-in resources, once be scheduled and used to UE10 time, and UE is used the number of times of this access-in resource success access network to come to 7 times, for this access-in resource, its access success rate is 7/10=0.7.
If the switching priority of UE is low switching priority, for UE scheduling access success rate, be less than the access-in resource of the first access success rate threshold value A; If the switching priority of UE is middle switching priority, for UE dispatches the access-in resource that is greater than the first access success rate threshold value A and is less than the second access success rate threshold value B; If the switching priority of UE is the high priority of switching, for UE scheduling, be greater than the access-in resource of the second access success rate threshold value B.
In embodiments of the present invention, can list with the form of list the access success rate of each access-in resource, also can show by the form that other can show access-in resource access success rate order.The access success rate that following table 2 is each access-in resource of listing with the form of list:
Table 2
Wherein, the quantity of predefined access success rate threshold value can be determined according to the number of switching priority level, if there be N to switch priority level, N-1 access success rate threshold value can be set.
Mode three, according to the switching priority of UE, and consider time order and function and the access success rate of the access-in resource that can be used for scheduling, be UE scheduling access-in resource.Specifically can be with reference to aforesaid way one and mode two, if in the manner described above one, the access-in resource that switches the UE scheduling of priority for height is 12 access-in resources in the T1 left side in time domain, and then also needing to consider has the access success rate of which access-in resource to be greater than the second access success rate threshold value B in these 12 access-in resources, can dispatch to UE accessing the access-in resource that success rate is greater than the second access success rate threshold value B in these 12 access-in resources.In like manner, for the access-in resource of the UE scheduling of middle switching priority be in time domain between T1 to T2 and the access-in resource of access success rate between threshold value A and B, for the access-in resource of the UE scheduling of low switching priority in time domain in the T2 right side and access the access-in resource that success rate is less than threshold value A.
In the above-mentioned specific embodiment of the present invention, the switching priority of UE can be divided into high, medium and low three and switch priority level, certainly according to the difference of concrete application scenario and environment, also can be divided into high and low two and switch priority level, can also be divided into the highest, inferior high, medium and low four and switch priority level, being specifically divided into several switching priority levels can determine according to application demand.
