Description

A method and base station for obtaining the number of access attempts

technical field

The present invention relates to the field of communications, in particular to a method for acquiring the number of access attempts and a base station.

Background technique

Because NB-Iot (Narrow Band Internet of Things, Narrowband Internet of Things) is an Internet of Things technology based on 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution) standard protocol evolution, and Compared with the existing mobile network, it has the characteristics of high spectrum resource utilization, support for a large number of low-speed users, large coverage depth, and low power consumption of terminals. Therefore, NB-Iot has become more and more favored by operators. As far as the coverage depth of NB-Iot is concerned, 3GPP stipulates that NB-Iot has a 20dB improvement in coverage compared with GPRS (General Packet Radio Service), and the base station will divide its coverage into three coverage levels , MCL (Maxim coupling loss, the maximum coupling loss) is 144, 154, 164 respectively, the downlink brings coverage enhancement through data repetition, and the uplink brings coverage enhancement through data repetition and improving the uplink power spectral density; In NB-Iot, in each level of coverage of the base station, the number of random access attempts of the user terminal is configured on the base station, regardless of whether the user terminal is in the middle of the coverage of this level or far away from the edge of the base station, it will be due to The preset rule uses the set number of access attempts to try to access the cell under the coverage of the base station, but when the user terminal itself is in a certain level of coverage and far from the edge of the base station, the signal is already very poor, but still It is necessary to try to access with the number of access attempts set by the base station. After the access fails, the number of access attempts will be increased to the number of access attempts corresponding to a higher level of coverage. Try to access according to the number of access attempts and access parameters corresponding to the coverage area, which will increase the access delay and occupy the random access channel used by the terminal uplink for a long time.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used for example, illustration or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

It should also be noted that, in the embodiments of the present invention, "的 (English: of)", "corresponding (English: corresponding, relevant)" and "corresponding (English: corresponding)" can sometimes be used in combination. It should be pointed out that , when the difference is not emphasized, the meanings they want to express are consistent.

In the prior art, with reference to the corresponding base station shown in Figure 1, three levels of coverage (0, 1, 2) are set according to the coverage distance, and each level of coverage is aimed at a certain range of RSRP values (which can reflect the signal The greater the RSRP, the stronger the signal), because the output power of each base station is uncertain, resulting in different RSRPs of user terminals at the same location of different base stations, but the loss characteristics of signal power sent by all similar base stations are the same, so In Figure 1, the difference MCL between the output power of the base station and the RSRP value of the user terminal is shown. The MCL value range for the coverage of the first level (CEL0) is (0dB, 144dB), and the coverage of the second level (CEL1) The MCL value range for the third level (CEL 2) coverage is [154dB, 164dB). For each level of coverage, the base station will set the user terminal to access When the user terminal accesses the network within a certain level of coverage, if the number of access attempts exceeds the number of access attempts set by the base station, it will use a higher level of access attempts set by the base station The number of access times and access parameters continue to try; this creates a problem: when the user terminal accesses in a place with poor signal farther away from the base station within a certain level of coverage, it is obvious that the current level of coverage corresponds to It is difficult to access the network when the number of access attempts and parameters of the user terminal itself are used as the number of access attempts and access parameters of the user terminal itself, but because the base station corresponds to the setting of the number of access attempts, the user terminal must try many times before it Higher levels of access attempts and parameters are used to access the network, which increases the delay of user terminals accessing the network, and the user terminal will occupy the random access channel and occupy communication resources during the access process.

In view of the above problems, as shown in FIG. 2, an embodiment of the present invention provides a method for obtaining the number of access attempts, including:

201. Obtain the reference signal received power RSRP value of each user terminal within all levels of coverage of the base station and the number of user terminals within each level of coverage of the base station.

202. Divide the coverage of each level of the base station into n layers according to the preset RSRP value and the difference between the maximum and minimum RSRP values of all user terminals within the coverage of each level of the base station.

Wherein, the first layer of the coverage of each level of the base station is the layer containing the minimum value of the RSRP values of all user terminals within the coverage of the current level, and the nth layer of the coverage of each level of the base station is Contains the layer with the maximum value among the RSRP values of all user terminals within the coverage of the current level, n is greater than or equal to 2 and is an integer; the number of layered layers specifically refers to the following formula:

n=(Max_RSRP_UE_CEj-Min_RSRP_UE_CEj)/S;

Among them, Max_RSRP_UE_CEj is the maximum value of the RSRP values of all user terminals within the j-level coverage of the base station, Min_RSRP_UE_CEj is the minimum value of the RSRP values of all user terminals within the j-level coverage of the base station, and S is a preset RSRP value, round up when n is a decimal, for example, when n is calculated as 5.4, the value is 6; because the base station has three levels of coverage, which are level 0 coverage, level 1 coverage and level 2 coverage, So j ∈ [0,1,2].

203. According to the RSRP value of each user terminal in the coverage area of all levels of the base station and the RSRP value range of the user terminal in each level of the coverage area of the base station, obtain each user terminal in the coverage area of each level of the base station The number of user terminals in the layer.

Specifically, the RSRP value of the user terminal in the t-th layer in the coverage area of the j-th level of the base station needs to satisfy:

Min_RSRP_UE_CEj+(t-1)S≤RSRP_UEi_CEj<Min_RSRP_UE_CEj+tS;

Where RSRP_UEi_CEj is the RSRP value of any user terminal in the t-th layer in the j-th level of coverage, 1≤t≤n and is an integer, and the range of RSRP_UEi_CEj is the t-th layer in the j-th level of coverage of the base station RSRP value range of the user terminal.

204. Calculate the number of access attempts of user terminals within the coverage of each level of the base station according to the number of user terminals on each layer within the coverage of each level of the base station and the number of user terminals within the coverage of each level of the base station .

The method for obtaining the number of access attempts provided by the above embodiments, according to the quality of the signal received by the user terminal (determined by RSRP), obtains the distribution of the number of user terminals within the coverage of each level of the base station, that is, each level of the base station The number of user terminals in each layer of the coverage area of the base station, and then according to the distribution of the number of user terminals in the coverage area of each level of the base station, set the number of user terminals in the coverage area of each level of the base station when accessing the cell network to which the base station belongs The number of access attempts, because the number of access attempts of user terminals within the coverage of each level of the base station set in this scheme is the proportion of the number of user terminals that receive signals of different quality within the coverage of the current level Correlation, so it can make the user terminals in each level of coverage of the base station try to access the cell network with the proportion of user terminals that receive signals of different qualities in the current level of coverage. Changes, the more the proportion of user terminals receiving poor signal quality, the smaller the number of user terminal access attempts of the corresponding current level of coverage, and the faster the user terminal attempts to access The number of access attempts and access parameters are upgraded to higher-level access attempts and access parameters, so that the number of access attempts required by the user terminal when accessing the cell network is reduced, and the user terminal is prevented from accessing the cell network. The problem of over-extending.

Referring to FIG. 3 , the embodiment of the present invention also provides a method for obtaining the number of access attempts as a supplement to the method for obtaining the number of access attempts provided in the above embodiment, including:

301. Acquire the reference signal received power RSRP value of each user terminal within all levels of coverage of the base station and the number of user terminals within each level of coverage of the base station.

302. Divide the coverage of each level of the base station into n layers according to the preset RSRP value and the difference between the maximum and minimum RSRP values of all user terminals within the coverage of each level of the base station.

Wherein, the first layer of the coverage of each level of the base station is the layer containing the minimum value of the RSRP values of all user terminals within the coverage of the current level, and the nth layer of the coverage of each level of the base station is A layer that includes the maximum value among the RSRP values of all user terminals within the coverage of the current level, and n is greater than or equal to 2 and is an integer.

303. According to the RSRP value of each user terminal in the coverage area of all levels of the base station and the RSRP value range of the user terminal in each level of the coverage area of the base station, obtain each user terminal in the coverage area of each level of the base station The number of user terminals in the layer.

3041. When j is 0 or 1, according to the sum of the number of user terminals from the first layer to the kth layer within the jth level coverage of the base station, the (k+1)th layer to the (k+1)th layer to the jth level coverage of the base station The sum of the number of user terminals on the nth level and the number of user terminals within the jth level coverage of the base station is used to calculate the number of attempted accesses of the user terminals within the jth level coverage of the base station according to a first preset formula.

Exemplarily, the first preset formula is:

Among them, PT_j is the number of attempted accesses of user terminals within the j-th level coverage of the base station, α is the first preset coefficient, β is the second preset coefficient, and Num_j[m] is the j-th level coverage of the base station The number of user terminals on the mth layer within the range, UE_Num_total_CEj is the number of user terminals within the jth level coverage of the base station; the sum of α and β is 1 and α is less than β;

Among them, j∈[0,1,2]; when n is an even number, k=n/2, when n is an odd number, k=(n-1)/2, of course, when n is an odd number, it does not affect the basis of calculation In the above, k can also be (n+1)/2, which needs to be set with reference to actual data; in this embodiment, the j-th level coverage of the base station is far away from half of the base station (the RSRP of the user terminal is small). The coverage area (from the first layer to the kth layer) is used as the part of the poor signal (actually, it is selected according to the actual situation, not limited to choosing half of the coverage area far away from the base station), and then it is necessary to use the preset calculation formula to make the number of access attempts increase with the The number of user terminals with poor signal increases and decreases.

3042. If j is 2, according to the sum of the number of user terminals from the first layer to the kth layer within the coverage area of the jth level of the base station, and the number of user terminals from the (k+1)th layer to the nth layer within the coverage area of the jth level of the base station The sum of the number of user terminals and the number of user terminals within the j-th level coverage of the base station calculates the number of attempted accesses of the user terminals within the j-th level coverage of the base station according to a second preset formula.

Exemplarily, the second preset formula is:

It should be noted that, if the result of the number of access attempts calculated according to the above two formulas is a decimal, it will be rounded down. For example, when the calculation result of the number of access attempts is 16.6, it is determined that the number of access attempts is 16; In the example, when j is 0 or 1 and when j is 2, the calculation formula for the number of access attempts is different mainly because the second-level coverage of the base station is the part farthest from the base station, and the signal itself is relatively poor, so when calculating It is necessary to make the number of access attempts change faster than when j is 0 or 1.

In addition, the values of α and β in the foregoing embodiments are determined according to actual conditions, and are not specifically limited in the embodiments of the present invention.

In order to more clearly show the beneficial effects that can be achieved by the method for obtaining the number of access attempts provided by the embodiment of the present invention, the number of user terminals at the first level of a certain base station is 1000, divided into 10 layers, and α is 0.3, and β is 0.7 as an example to illustrate:

When the sum of the number of user terminals from the first layer to the fifth layer of the second level is 300, and the sum of the number of user terminals from the sixth layer to the tenth layer is 700, PT_j=6*(0.3*300+0.7*700)/ 1000＝3.48 is rounded down to 3;

When the sum of the number of user terminals from the first layer to the fifth layer of the second level is 600, and the sum of the number of user terminals from the sixth layer to the tenth layer is 400, PT_j=6*(0.3*600+0.7*400)/ 1000=2.76 is rounded down to 2;

It can be clearly concluded that the number of access attempts decreases as the number of user terminals from layer 1 to layer 5 of the second level increases, that is, the more user terminals with poor signals in the coverage area of the second level of the base station, The smaller the number of access attempts, the faster the user terminal can select a higher level of access attempts and parameters for network access;

Similarly, it can be seen that the calculation formula of the number of access attempts provided by the present invention for the coverage area of the base station at level 0 or level 1 can also achieve the above effect.

The method for obtaining the number of access attempts provided by the embodiment of the present invention, because the method includes: obtaining the reference signal received power RSRP value of each user terminal within the coverage of the base station and the number of user terminals within the coverage of each level of the base station ; According to the preset RSRP value and the difference between the maximum and minimum values of the RSRP values of all user terminals within the coverage of each level of the base station, the coverage of each level of the base station is divided into n layers; The first layer of the coverage area of each level is the layer closest to the base station within the coverage area of the current level, and the nth layer of the coverage area of each level of the base station is the layer farthest from the base station within the coverage area of the current level; n is greater than or equal to 1 and is a positive integer; obtain the coverage of each level of the base station according to the RSRP value of each user terminal within the coverage of the base station and the RSRP value range of each layer of user terminals within the coverage of each level of the base station The number of user terminals in each layer within the range; calculate the coverage of each level of the base station based on the number of user terminals in each level of the coverage of the base station and the number of user terminals within the coverage of each level of the base station The number of access attempts PT of internal user terminals. According to the technical solution provided by the embodiment of the present invention, the distribution of the number of user terminals within the coverage of each level of the base station can be obtained according to the quality of the signal received by the user terminal (determined by RSRP), that is, the coverage of each level of the base station According to the distribution of the number of user terminals in the coverage area of each level of the base station, set the number of user terminals in the coverage area of each level of the base station when accessing the cell network to which the base station belongs. number of entries. Because the solution provided by the embodiment of the present invention sets the number of access attempts of user terminals within the coverage of each level of the base station to the ratio of the number of user terminals receiving signals of different quality within the coverage of the current level Correlation, so it can make the user terminals in each level of coverage of the base station try to access the cell network with the proportion of user terminals that receive signals of different qualities in the current level of coverage. Changes, the more the proportion of user terminals receiving poor signal quality, the smaller the number of user terminal access attempts of the corresponding current level of coverage, and the faster the user terminal attempts to access The number of access attempts and access parameters are upgraded to higher-level access attempts and access parameters, so that the number of access attempts required by the user terminal when accessing the cell network is reduced, and the user terminal is prevented from accessing the cell network. The problem of over-extending.
