These services have the characteristics of large number of users and frequent occurrence. , occupying a large amount of uplink network bandwidth, but the uplink channel utilization rate is low. For example, a heartbeat of a service can transmit effective data within 1 second, but occupy the channel for about 21 to 22 seconds. Heartbeat packets occupy wireless resources for most of the time instead of As a result, services that really need uplink bandwidth cannot obtain the required resources, or even access the network, thereby causing user perception to be affected or network congestion.

It can be seen that there are many unreasonable features in the current uplink bandwidth allocation mechanism, which does not take into account the differences in uplink bandwidth requirements of different types of services, resulting in impacts on network resource utilization and user perception.

Detailed ways

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 creative efforts fall within the protection scope of the present invention. In addition, each of the following embodiments is an optional solution of the present invention, and the arrangement sequence and number of the embodiments have nothing to do with their preferred execution order.

Example 1

According to an embodiment of the present invention, a method for allocating an uplink bandwidth value is provided, as shown in FIG. 1 , the method includes:

Step 101 , for an initial access data service, the RNC (Radio Network Controller) determines whether there is an uplink idle code channel in the uplink bandwidth of each carrier.

Specifically, when the data service is initially accessed, the RNC obtains the uplink bandwidth value of each carrier (in this embodiment, the carrier is described as an H carrier), and determines whether there is Uplink idle channel.

Among them, the uplink bandwidth value can be obtained according to the carrier configuration. For example, if an H carrier is configured with an available uplink bandwidth of 224Kbps, the RNC can obtain the used uplink bandwidth. The available uplink bandwidth - the used uplink bandwidth = the remaining available uplink bandwidth. It means that there is an uplink free code channel.

Step 102, for the carriers with uplink idle code channels, the RNC determines the access carriers and access code channels for data service access according to the acquired initial parameters and collected data of the carriers with uplink idle code channels.

This step 102 specifically includes: the RNC acquires initial parameters and collection data of each carrier with uplink idle code channels, the initial parameters and collection data include: idle uplink bandwidth value, uplink interference value, and downlink available power value; these values are known to RNC.

RNC sorts each carrier according to the idle uplink bandwidth value of each carrier, as an alternative access carrier; wherein, the preferred solution is to use the carrier with the largest idle uplink bandwidth after sorting as the first candidate access carrier.

According to the arrangement sequence of the candidate access carriers, the RNC performs calculations according to the free uplink bandwidth value, uplink interference value, and downlink available power value of each carrier, and then determines the access carrier.

That is: the RNC calculates and determines the access carrier for each carrier. The most optimal way can adopt the method of weighted summation. Refer to formula 5 below.

φ _i ＝α*η _i1 +β*η _i2 +δ*η _i3 (5)

in, Indicates the determined access carrier of carrier i; α, β, δ represent the weight of each item; η _i1 = idle uplink bandwidth value of carrier i/total uplink bandwidth of carrier i; η _i2 = uplink interference value of carrier i/all The maximum uplink interference of the carrier; η _i3 = the downlink available power value of carrier i/the maximum downlink available power value of all carriers; the carrier with the largest calculation result of each carrier is selected as the selected carrier.

The RNC selects an uplink idle code channel as the access code channel on the determined access carrier. And the RNC can select any uplink idle code channel on the confirmed access carrier as the access code channel.

Step 103, for the carrier that does not have an uplink idle code channel, calculate the uplink bandwidth idle coefficient of each carrier according to the obtained resource status data of each carrier, and determine according to the uplink bandwidth idle coefficient of each carrier, the initial parameters of each carrier and the collected data For the access carrier used for data service access, the access code channel used for accessing the data service is determined according to the resource status data of each code channel of the access carrier.

Specifically, the step 103 is:

The RNC obtains the resource status data of each carrier (the RNC can obtain these data from the NodeB), and the resource status data of each carrier includes: the number of code channels of the code channel groups that have been occupied but not transmitted, and the The code channel idle time of the code channel group, the total number of users accessing the carrier;

For each carrier in each carrier, the RNC calculates the uplink bandwidth idle factor of the carrier in the following manner:

The RNC calculates the uplink bandwidth idle factor of the carrier according to the number of code channels of the code channel groups that are occupied but not transmitting data, the code channel idle time of the code channel groups that are occupied but not transmitted, and the total number of users of the carrier.

The specific calculation method can refer to the following formula 1.

The formula 1 for calculating the idle factor of the uplink bandwidth of the carrier is:

Where R _i represents the uplink bandwidth idle factor of H carrier i, φ _j represents the code channel number of code channel group j that is occupied but not transmitting data, Indicates that the code channel idle time j of the code channel group j that is occupied but not transmitting data ranges from 1 to 15, and N indicates the total number of users accessing the carrier.

RNC sorts each H carrier according to the calculated uplink bandwidth idle coefficient of each H carrier;

The RNC comprehensively determines the access carrier used for data service access according to the uplink bandwidth idle coefficient of each carrier and the initial parameters and collected data of each carrier according to the order of the size of the uplink bandwidth idle coefficient after the arrangement, wherein the initial parameter and the collected data Including: idle uplink bandwidth value, uplink interference value, downlink available power value. For a specific calculation method, reference may be made to the above formula 5, which will not be repeated here.

On the determined access carrier, the RNC calculates the idle coefficient of each uplink code channel according to the resource status data of each uplink code channel. The resource status data of each uplink code channel includes: code channels that have been occupied but have not transmitted data The idle time of the code channel of the group and the total number of users accessing the code channel. The specific calculation method can refer to formula 2.

The formula (2) for calculating the idle coefficient of the uplink code channel is:

where α _j represents the idle coefficient of code channel group j that is occupied but not transmitting data, Indicates the code channel idle time of the code channel group j that has been occupied but has not transmitted data, and M indicates the total number of users accessing the code channel;

According to the calculated idle coefficients of each uplink code channel, the RNC selects the code channel with the largest idle coefficient of the uplink code channel as the access code channel of the data service.

In addition, in the preferred solution of this embodiment, the following uplink bandwidth dynamic adjustment solution is included:

1) Uplink bandwidth convergence scheme

When the uplink code channel utilization rate of any H carrier is higher than the first threshold threshold1, the RNC calculates the uplink rate of each user on the uplink code channel;

According to the relationship between the uplink rate of each user and the preset rate threshold, the uplink code channel of the low-active user who occupies resources for a long time is adjusted.

For example: the network side adjusts the uplink bandwidth based on the uplink rate of each user. The uplink rate can be analyzed by the RNC at the RLC (Radio Link Control) layer and PDCP (Packet Data Convergence Protocol) layer. Calculate the amount of data transmitted per user unit time (since the method for calculating the uplink rate is commonly used in the prior art, so it will not be described here), and according to the preset rate threshold (S1, S2, S3) Adjust the uplink code channel corresponding to the data service, so that users with low uplink rate requirements converge to the same uplink code channel as much as possible. The specific adjustment formula is as follows: Equation 3: adjust the user whose uplink rate is lower than S1 to ₈ Double the uplink frame division multiplexing code channel, adjust the user whose uplink rate is between S ₁ and S ₂ to 4 times the frame division multiplexing code channel, and adjust the user whose uplink rate is between S ₂ and S ₃ to 2 times frame division multiplexing code channel. For details, please refer to the following formula (3)

Among them, S _i represents the uplink rate of a user i, S ₁ represents the uplink rate threshold of 8 times the frame per user, S ₂ represents the uplink rate threshold of 4 times the frame per user, and S ₃ represents the uplink rate threshold of 2 times the frame per user.

2) Uplink bandwidth dynamic adjustment scheme

When the uplink bandwidth value of any H carrier is higher than the second threshold threshold2, the RNC calculates the uplink rate of each user on the access uplink bandwidth, and according to the difference between the uplink rate of each user and the preset rate threshold The relationship adjusts the uplink code channel of low-activity users who occupy resources for a long time;

When there is no free uplink code channel and the user needs to adjust it, RNC bases on the number of code channels required by the user, the code channel idle time of the code channel group that is occupied but not transmitting data, and the total number of users accessing the code channel Determine the adjustment plan.

For example: a) When the uplink bandwidth of the H carrier is higher than the set threshold Threshold2, the RNC evaluates the uplink rate of a single user, and adjusts the uplink code channel when the uplink rate of a user meets the conditions of the following formula (4):

Among them, S _i represents the uplink rate of a certain user, S ₁ represents the uplink rate threshold of 8 times the frame per user, S ₂ represents the uplink rate threshold of 4 times the frame per user, and S ₃ represents the uplink rate threshold of 2 times the frame per user.

b) When there is no idle code channel in the uplink and the user needs to adjust the uplink rate, use the following method to select the code channel used for the uplink:

According to the number of code channels Ki required for user i to increase the uplink bandwidth, calculate the idle coefficient of the user's uplink code channel with the same number of code channels as Ki, and judge whether it satisfies If the condition is greater than the preset threshold and M is less than the preset threshold, for the code channels that meet the conditions, select the code channel with the largest uplink code channel idle factor as the code channel allocated after the user is up-regulated; if there is no code channel that meets the conditions, then Select the code channel with the next number of code channels lower than Ki for the above judgment, and access if a suitable code channel is found; if no suitable code channel can be found after trying all possibilities, no debugging is performed.

This embodiment is described by taking the H carrier as an example, but in fact, other carriers, such as the R4 carrier, may also be used. Since the specific implementation manner at this time can be easily understood by those skilled in the art based on the content described in this embodiment, details are not described here.

In the method provided in this embodiment, for the initial access data service, the data related to resources and services such as carrier resource status, initial parameters, and collected data are used to determine a suitable access carrier and code channel for the initial data service. It solves technical problems such as low resource utilization rate and unreasonable allocation mechanism of uplink bandwidth allocation in the prior art, and then realizes that the network can allocate network uplink bandwidth according to service characteristics and network resource utilization efficiency, improve network utilization rate, and reduce network congestion. technical effect.
