Referring to fig. 1, an embodiment of the present invention provides a method for estimating a newly added resource when accepting a decision, which specifically includes:
step 10: when a base station receives a service admission request from a terminal/source base station, determining the pre-retransmission times of the service;
in this step, the counted average retransmission times of the data packet may be used as the pre-retransmission times of the service, and the specific statistical methods include the following three methods:
first, the average retransmission times of the data packet of the UE in a period of time before the decision time is counted, and the counted result is used as the pre-retransmission times of the service. The period of time may be any length of time set.
For example, as an example of the following behavior, the number of times N that the base station transmits the retransmission packet to the UE within a time period T before the decision time is counted firstretrCounting the number N of times that the base station sends the initial transmission data packet to the UE in the time period T before the decision timeinitThen calculating the average weightNumber of transmissions N ═ Nretr/Ninit。
In the above embodiment, the number N of times that the base station receives the retransmitted data packet from the UE within the time period T before the decision time is counted firstretrCounting the number N of times of initial transmission of data packets from the UE by the base station in a time period T before the decision timeinitThen, the average retransmission number N is calculated as Nretr/Ninit。
According to the upper and lower behavior examples, firstly, the times N of retransmitting the data packet sent to the UE by the base station in the time period T before the decision time is countedretr1And the number N of times of receiving the retransmitted data packet from the UEretr2Counting the number N of times that the base station sends the initial transmission data packet to the UE in the time period T before the decision timeinitAnd the number N of times of receiving initial transmission data packets from the UEinit2Then, the average retransmission number N ═ N (N) is calculatedretr1+Nretr2)/(Ninit+Ninit2)。
Secondly, counting the average retransmission times of all service data packets in a cell where the UE is located within a period of time, and taking the counting result as the pre-retransmission times of the service. The period of time may be any length of time set.
For example, as an example of the following behavior, first, the number N of times that the base station transmits the retransmission packet to m UEs in the cell in the T period before the decision time is countedretr1、Nretr2、Nretr3...、NretrmCounting the number N of times that the base station sends the initial transmission data packet to m UEs in the cell in the T time period before the judgment timeinit1、Ninit2、Ninit3...、NinitmThen, the average retransmission number N ═ N (N) is calculatedretr1+Nretr2+Nretr3+...+Nretrm)/(Ninit1+Ninit2+Ninit3+...+Ninitm)。
In the above behavior example, the number N of times that the base station receives the retransmitted data packets sent by m UEs in the local cell in the T period before the decision time is counted firstretr1、Nretr2、Nretr3...、NretrmCounting the number N of times that the base station receives the initial transmission data packets from m UEs in the cell in the T time period before the decision timeinit1、Ninit2、Ninit3...、NinitmThen, the average retransmission number N ═ N (N) is calculatedretr1+Nretr2+Nretr3+...+Nretrm)/(Ninit1+Ninit2+Ninit3+...+Ninitm)。
According to the upper and lower behavior example, firstly, the times N of the retransmission data packet sent by the base station to the m UEs of the local cell in the T time period before the decision time is countedretr11、Nretr21、Nretr31...、Nretrm1And the number N of times that the base station receives the retransmission data packet sent by the m UEs in the cellretr12、Nretr22、Nretr32...、Nretrm2(ii) a Counting the number N of times that the base station sends the initial transmission data packet to m UEs of the cell in the T time period before the judgment timeinit11、Ninit21、Ninit31...、Ninitm1And the number N of times of receiving initial transmission data packets from m UEs in the cell by the base stationinit12、Ninit22、Ninit32...、Ninitm2(ii) a Then, the average retransmission number N ═ N is calculatedretr11+Nretr21+Nretr31+...+Nretrm1)+(Nretr12+Nretr22+Nretr32+...+Nretrm2)]/[(Ninit11+Ninit21+Ninit31+...+Ninitm1)+(Ninit122+Ninit22+Ninit32+...+Ninitm2)]。
Thirdly, counting the average retransmission times of the service data packet in the cell where the UE is located and the service data packet has the same type as the service requested to be admitted by the UE within a period of time, and taking the counting result as the pre-retransmission times of the service. The period of time may be any length of time set.
For example, the following behavior example first counts the T period before the decision timeThe times X of retransmitting data packets which are sent to m UEs of the cell by the inner base station and have the same service type as the UE requests to admitretr1、Xretr2、Xretr3...、XretrmCounting the times X of initial transmission data packets which are sent by a base station to m UEs of the cell and have the same service type with the UE request in the T time period before the decision timeinit1、Xinit2、Xinit3...、XinitmThen, the average retransmission number n ═ X is calculatedretr1+Xretr2+Xretr3+...+Xretrm)/(Xinit1+Xinit2+Xinit3+...+Xinitm)。
According to the above behavior example, firstly, the times X of retransmission data packets, which are received by the base station in the T time period before the decision time and are from m UEs in the cell and have the same service type as the UE requesting to accept, are countedretr1、Xretr2、Xretr3...、XretrmCounting the times X of initial transmission data packets which are received by the base station in the T time period before the decision time and are from m UEs of the cell and have the same service types as the services requested to be admitted by the UEsinit1、Xinit2、Xinit3...、XinitmThen, the average retransmission number n ═ X is calculatedretr1+Xretr2+Xretr3+...+Xretrm)/(Xinit1+Xinit2+Xinit3+...+Xinitm)。
According to the upper and lower behavior examples, firstly, counting the times X of retransmitting data packets which are sent by a base station to m UEs of a cell and have the same service types as the UE requests to be admitted in a T time period before a decision timeretr11、Xretr21、Xretr31...、Xretrm1And the times X of retransmission data packets which are received by the base station from m UEs of the cell and have the same service type as the UE requests to be admittedretr12、Xretr22、Xretr32...、Xretrm2(ii) a Counting the times X of initial transmission data packets which are sent to m UEs of the cell by a base station in a T time period before the decision time and have the same service type with the UE requestinit11、Xinit21、Xinit31...、Xinitm1And the number X of times that the base station receives the initial transmission data packet which is from m UEs of the cell and has the same service type as the UE requests to be admittedinit12、Xinit22、Xinit32...、Xinitm2(ii) a Then, the average retransmission number n ═ X is calculatedretr11+Xretr21+Xretr31+...+Xretrm1)+(Xretr12+Xretr22+Xretr32+...+Xretrm2)]/[(Xinit11+Xinit21+Xinit31+...+Xinitm1)+(Xinit12+Xinit22+Xinit32+...+Xinitm2)]。
It should be noted that the first statistical method is applicable to a case where the UE requesting service admission has a service in communication in the current cell, for example, the UE in communication initiates establishment of a new service, and the UE requests an increase in rate for the established service. The second and third statistical methods are applicable to the case where the UE requesting service admission has no ongoing communication service in the current cell, for example, the UE initiates establishment of the first service, the UE performs handover, and the like.
In this step, the number of pre-retransmissions may also be determined according to a preset setting, and specifically, there are the following three ways:
in the first kind of the method, the first,
firstly, presetting a corresponding relation between a distance parameter value and an average retransmission time;
here, the distance is a distance between the base station and the terminal, and the correspondence may be a one-to-one correspondence or a many-to-one correspondence, where a many-to-one indicates that distance parameter values within a certain range correspond to the same average number of retransmissions. For example, a distance of 0 to 1km is set corresponding to the average number of retransmissions n1The average retransmission number n corresponding to the distance of 1km to 5km2The average retransmission number n corresponding to the distance of 5km to 10km3The distance of 10km to 20km corresponds to the average number of retransmissions n4Greater than 20kmDistance-corresponding average number of retransmissions n5。
Then, determining the actual distance between the UE requesting service admission and the base station;
the UE can determine the distance between the UE and the base station according to the difference between the receiving power of the UE and the transmitting power of the base station, and report the determined distance value to the base station periodically, so that the distance value between the UE and the base station can be acquired from the information reported by the terminal.
And then, determining the average retransmission times corresponding to the actual distance according to the established corresponding relation between the distance parameter value between the base station and the terminal and the average retransmission times, and taking the average retransmission times as the pre-retransmission times. For example, if the actual distance between the UE and the base station is determined to be 2km, the set average number of retransmissions corresponding to 2km is n2Then n will be2As the final determined number of pre-retransmissions.
In the second type of the above-mentioned methods,
firstly, presetting a corresponding relation between a Channel Quality Information (CQI) value and an average retransmission time;
here, the correspondence relationship between the CQI value and the average number of retransmissions may be a one-to-one correspondence relationship, or may be a many-to-one correspondence relationship, where many-to-one indicates that CQI values within a certain range correspond to the same average number of retransmissions.
Then, determining the current CQI value;
here, the current CQI value may be specifically obtained from information reported by the UE requesting service admission; if not, the average CQI value of the cell can be used as the current CQI value, and the average CQI value of the cell is calculated by averaging the CQI values reported by other UEs to obtain the current CQI value.
And then, determining the average retransmission times corresponding to the current CQI value according to the established corresponding relation between the CQI value and the average retransmission times, and taking the average retransmission times as the pre-retransmission times.
In a third aspect of the present invention,
firstly, presetting a corresponding relation between a service quality of service (QoS) value and an average retransmission time;
here, the correspondence relationship between the QoS value and the average retransmission number may be a one-to-one correspondence relationship, or a many-to-one correspondence relationship, where a many-to-one correspondence relationship indicates that QoS values within a certain range correspond to the same average retransmission number.
Then, determining the current QoS value;
here, the QoS value in the service admission request sent by the UE may be specifically used as the current QoS value.
And then, according to the established corresponding relation between the channel quality parameter value or the service quality parameter value and the average retransmission times, determining the average retransmission times corresponding to the current channel quality or service quality, and taking the average retransmission times as the pre-retransmission times.
It should be noted that the three statistical methods are applicable to the case where the UE requesting service admission has a service in communication in the current cell, for example, the UE in communication initiates establishment of a new service, and the UE requests an increase in rate for the established service. The method is also applicable to services that the UE requesting service admission does not have in communication in the current cell, for example, the UE initiates establishment of the first service, the UE performs handover, and the like.
Step 11: determining retransmission occupied resources of the service according to the pre-retransmission times and the estimated initial transmission occupied resources;
in this step, the product of the pre-retransmission times and the estimated size of the resource occupied by the initial transmission of the service is calculated, and the calculation result is used as the size of the resource occupied by the retransmission of the service. The size of the resources occupied by the initial transmission can be estimated according to the service rate and channel conditions requested by the UE.
Step 12: and estimating resources occupied by the service needing to be newly added according to the retransmission occupied resources.
In this step, the sum of the size of the resource occupied by the retransmission of the service and the size of the resource occupied by the initial transmission is calculated, and the calculation result is used as the size of the resource occupied by the service needing to be newly added.
After the size of the resource occupied by the service which needs to be newly increased is estimated, service admission judgment can be carried out according to the estimation result: if the sum of the occupied resource size and the estimated newly-increased occupied resource size is larger than the resource utilization threshold value, refusing to admit the service, otherwise, admitting the service.
