Description

A Resource Allocation Method

technical field

The present invention relates to the resource allocation technology in the mobile communication system, in particular to the resource allocation method when the Multimedia Broadcast/Multicast Service (MBMS) and conventional services are concurrent.

Background technique

MBMS is defined in 3GPP R6 as a downlink multimedia service realized on the basis of packet service (PS) domain packet network, and is a standard for mobile TV services. MBMS is a broadcast service, and the same service content is broadcast simultaneously in a service area (generally including multiple cells), so that when UE moves in multiple cells in the service area, it can receive uninterruptedly. In order to ensure the synchronization of MBMS broadcasting in different cells and the synchronous reception of UEs when they move freely in the service area, MBMS services in multiple cells in a service area must occupy the same physical resources, including frequency points, time slots and code channels .

Since the MBMS technology allows mobile phones to receive MBMS services when activating non-MBMS services, that is, conventional services including voice services and packet services, there are many concurrent scenarios of MBMS and conventional services in practical applications.

For the current R4 and R5 mobile phones, because they do not have the ability to support multiple carriers, they can only receive data on one carrier at the same time. Therefore, if they want to receive data from different carriers, they can only be done in different time slots After switching the frequency point, it needs to be stable for a certain period of time before the data of the new frequency point can be received correctly after the frequency point conversion is completed (see MBMS industry standard). In this way, when the two services use different carrier resources, they must use different and non-adjacent time slot resources, that is, to meet the requirements of time slots with different frequency intervals, so that the mobile phone can have sufficient time to switch frequency points. It can be seen that in the concurrent scenario of MBMS and conventional services, the network side needs to try its best to configure the concurrent MBMS and conventional service channels on the carrier resources of the same frequency or different frequency and time slots, so as to realize the above two services on the mobile phone side. concurrent.

Dynamic Channel Allocation (DCA) technology is a technology adopted by existing systems for resource allocation for conventional services. This technology uses comprehensive information in the system to allocate, manage and schedule all resources in the system to maximize the use of system resources and ensure the performance of links and systems. An important function of dynamic channel allocation is to use a reasonable method to select the frequency point and time slot resources of the cell to accept services. Its purpose is to balance the bearing capacity of each frequency point and maximize the use of system resources. For the frequency point and time slot resource allocation methods of conventional services implemented in accordance with DCA technical requirements in non-concurrent scenarios, many relatively mature methods have been proposed. The following are two more commonly used methods: one is to use fixed frequency Point, slot priority method. In this method, the priority of each frequency point and time slot in the cell is pre-configured in the operation and maintenance interface (O&M). The other is the method based on the number of idle code channels. This method sorts all frequency points and time slot resources according to the number of idle code channels. If there are many idle code channels, the priority of the frequency point or time slot is high. The frequency points and time slots with the largest number of idle code channels are allocated to the services that need to be accessed. In practical applications, there are still some methods based on the deformation and combination of the above two methods, which will not be listed here.

Through the above analysis, it can be seen that in the scenario where MBMS and conventional services are concurrent, when the network side configures frequency points and time slot resources for the concurrent services, two criteria need to be considered, that is, both the same frequency or Inter-frequency and time-slot restrictions also need to consider DCA technical requirements to achieve flexible control of system resources. For the sake of simplicity, the former standard is called the concurrent UE capability limitation standard, and the latter standard is called the frequency point/time slot selection standard of DCA.

The existing resource allocation method suitable for concurrent scenarios is to consider the two standards in series, that is, consider one standard first, and then consider another standard on this basis. That is to say, in the existing method, two rounds of frequency point and time slot resource selection are required. This method usually first considers the technical requirements of DCA, that is, to meet the load balancing requirements of each frequency point, and then performs a round of frequency point and time slot selection, and then considers two concurrency restrictions on this base station, that is, satisfies the same frequency or According to the requirements of different frequency interval time slots, the second round of frequency point and time slot selection is carried out; or, on the contrary, the concurrency limitation is considered first, and then the DCA technical requirements are considered. And when the above two standards cannot be taken into account, only one of them can be selected as the criterion for frequency point and time slot selection, and cannot be considered comprehensively. In addition, this method is not flexible enough to control frequency points and time slots, and cannot flexibly control the use of frequency points and time slot resources according to the actual wireless environment. For example, in some environments, it is better for two concurrent services to have the same frequency, and in some environments, it is better for two concurrent services to have different frequencies and time slots, but the above method cannot flexibly meet the requirements of these different application environments.

It can be seen that the existing resource allocation methods suitable for concurrent scenarios cannot truly realize the comprehensive consideration of business concurrency restrictions and DCA technical requirements, and cannot flexibly control the use of system frequency points and time slot resources according to actual needs.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a resource allocation method.

In order to achieve the above object, the technical scheme proposed by the present invention is:

A resource configuration method, when the network side needs to configure conventional service resources for UE in the concurrent scenario of MBMS service and conventional service, the method includes the following steps:

According to the DCA frequency point/time slot selection standard, determine the common priority value S _n of each frequency point;

According to the same-frequency or different-frequency characteristics of each frequency point and the frequency point used by the MBMS service and the determined common priority value S _n of each frequency point, use the same-frequency frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _sp or different frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _dp to determine the final priority value FP of each frequency point; where, F _ns is the known frequency with the DCA The first equalization factor corresponding to the point/slot selection standard, and its value range is [0, 1]; F _ss is a known second equalization factor corresponding to the concurrent UE capability limitation standard, and its value range is [0 , 1], and F _ns +F _ss =1; P _sp is the known parameter of the same-frequency priority value, and P _dp is the known parameter of the different-frequency priority value;

Preferably, the final priority value FP for determining each frequency point is:

Determine whether the frequency point is the same as the frequency point used by the MBMS service, if they are the same, according to the determined common priority value S _n of each frequency point, use the same frequency frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _sp to calculate the final priority value FP of the frequency point, otherwise, use the formula FP=F _ns ×S _n +F _ss ×P _dp to calculate the final priority value of the frequency point Priority value FP.

Preferably, in the scenario where the MBMS service and the regular service are concurrent, the regular service resource configuration for the UE is as follows:

When the UE requests to activate the regular service after the MBMS service has been activated;

When the UE requests to activate the MBMS service after the regular service has been activated;

When the UE has activated the MBMS service and the regular service, and adjusts the MBMS service;

When the UE activates the MBMS service and a voice service CS or packet service PS, and then activates the PS or CS service corresponding to the CS or PS service;

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The main idea of the present invention is: when the network side needs to configure conventional service resources for the UE in the concurrent scenario of MBMS service and conventional service, by proposing the concept of equalization factor corresponding to the concurrent UE capability restriction standard, the concurrent UE capability restriction condition is transformed into The evaluation parameter used in conventional DCA frequency point/slot selection is the priority value, so that the DCA frequency point/time slot selection standard and the concurrent UE capability restriction standard can be considered comprehensively during frequency and time slot selection , and then use the final priority value obtained according to the above two criteria to select frequency and time slot resources, so as to realize the real consideration of the above two resource selection criteria, and also according to the needs of actual application scenarios, through the user plane Resource selection parameters such as the equalization factor are adjusted to flexibly control the use of system frequency points and time slot resources.

What needs to be explained here is that, as mentioned above, MBMS services must occupy the same physical resources in multiple cells in a service area, and the resources used by MBMS services in a certain cell cannot be reconfigured independently. Therefore, in concurrent scenarios , when it is necessary to configure or adjust resources to meet the constraints of concurrent UE capabilities, usually only the resources used by the regular services of the cell can be configured or adjusted. Resource allocation realizes concurrent MBMS business and conventional business.

In the scenario where the MBMS service and the regular service are concurrent, there are many situations in which regular service resources need to be configured for the UE, and simple examples are as follows, but not limited to the following situations.

When the UE requests to activate the regular service after the MBMS service has been activated;

When the UE requests to activate the MBMS service after the regular service has been activated;

When the UE has activated the MBMS service and the regular service, and adjusts the MBMS service;

When the UE has activated the MBMS service and a CS or PS service, and then activates the PS or CS service corresponding to the CS or PS service;

When the UE has activated the MBMS service and the combined service of CS and PS, when deactivating the CS or PS service, it is necessary to reconfigure resources for the PS or CS service that has not been deactivated; or

When the UE has activated the MBMS service and regular service, it performs cell handover.

FIG. 1 is a schematic flow chart of Embodiment 1 of the present invention. As shown in Figure 1, when the network side needs to configure regular service resources for the UE in the concurrent MBMS service and regular service scenario, Embodiment 1 mainly includes the following steps:

Step 101, according to the frequency point/time slot selection standard of DCA, determine the normal priority value S _n of each frequency point.

In this step, the common priority value S _n of each frequency point can be determined by using the existing conventional service frequency point and time slot resource configuration method realized according to DCA technical requirements. That is to say, there may be various frequency point/time slot selection criteria of the DCA, for example, the general priority of each frequency point or time slot is proportional to its current number of idle code channels. It may also be: the general priority of each frequency point or time slot is a preset fixed value. The specific method of determining the general priority value of each frequency point is well known to those skilled in the art, and will not be repeated here.

It should be noted that, in order to distinguish from the final priority value of each frequency point or time slot obtained by combining the two standards in the present invention, the priority value obtained according to the frequency point/time slot selection standard of DCA in the present invention is called ordinary priority value.

Step 102, according to the same-frequency or different-frequency characteristics of each frequency point and the frequency point used by the MBMS service and the determined common priority value S _n of each frequency point, use the same-frequency frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _sp or different frequency frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _dp to determine the final priority value FP of each frequency point;

Wherein, F _ns is a known first equalization factor corresponding to the DCA frequency point/slot selection standard, and its value range is [0, 1]; F _ss is a known and concurrent UE capability limitation standard The corresponding second equalization factor has a value range of [0, 1], and F _ns + F _ss = 1; P _sp is a known same-frequency priority value parameter, and P _dp is a known different-frequency priority value parameter .

Among the above parameters, the first equalization factor F _ns and the second equalization factor F _ss respectively correspond to the above two standards. Through different settings of F _ns and F _ss , different emphases of the two standards can be realized. For example, when F _ns is greater than When F _ss is used, the DCA frequency point/slot selection standard will be emphasized during resource selection. When F _ns is less than F _ss , the concurrent UE capability limit standard will be emphasized. When F _ns is equal to F _ss , the The two criteria are considered in balance.

P _sp and P _dp are used to concretize the concurrent UE capability limitation standard in frequency point selection into the same frequency and different frequency interval time slots. By setting P _sp and P _dp differently, it is possible to realize the Different emphases of the same frequency or different frequency interval time slots, for example, when P _sp is greater than P _dp , then the frequency point selection will focus on selecting the same frequency point as the MBM service, when P _sp is smaller than P _dp , then It will focus on selecting a frequency point different from the MBM service, and when P _sp is equal to P _dp , it will take equal consideration of the same frequency and different frequency interval time slots. In practical applications, when the frequency point is different from the frequency point used by the MBMS service, and there is no time slot in the free time slot resources of the frequency point that satisfies the time slot interval condition with the time slot used by the MBMS service , the parameter P _dp is zero.

In this step, by introducing the first equalization factor and the second equalization factor, the DCA frequency point/time slot selection criterion and the concurrent UE capability limitation criterion adopt the same evaluation parameter, that is, the priority value. In this way, the above two criteria can be considered simultaneously when selecting a frequency point or a time slot. That is to say, the final priority value in this step is the final result of comprehensive consideration of the two criteria. After that, the frequency point with the largest final priority value can be selected from the frequency point resources at one time to allocate to the regular service , so as to realize the optimal allocation of resources.

In practical applications, the above parameters F _ns , F _ss , P _sp , and P _dp can be configured by network maintenance personnel through the user operation management platform on the network side. In this way, the above parameters can be dynamically configured according to the needs of actual scenarios, so that This makes the present invention more flexible in controlling the use of system frequency points and time slot resources.

Here, the specific method for determining the final priority value FP of each frequency point may be:

Determine whether the frequency point is the same as the frequency point used by the MBMS service, if they are the same, according to the determined common priority value S _n of each frequency point, use the same frequency frequency point priority value calculation formula FP=F _ns ×S _n +F _ss ×P _sp to calculate the final priority value FP of the frequency point, otherwise, use the formula FP=F _ns ×S _n +F _ss ×P _dp to calculate the final priority value of the frequency point Priority value FP.

Step 103, select the frequency point with the largest final priority value FP and allocate it to the regular service.

Here, according to the determined final priority value FP of each frequency point, the frequency resource configured for the regular service is determined.

Step 104, according to the DCA frequency point/time slot selection criterion, determine the normal priority value T _n of each time slot of the selected frequency point.

In this step, the DCA frequency point/time slot selection standard in step 101 will be used to determine the general priority value T _n of each time slot of the selected frequency point. The specific determination method is well known to those skilled in the art and will not be repeated here. repeat.

Step 105, determine whether the selected frequency point is the same as the frequency point used by the MBMS service, if yes, select the uplink time slot and the normal priority value with the largest common priority value _T from each time slot of the selected frequency point The downlink time slot with the largest T _n is allocated to the regular service, otherwise, according to the formula TP=F _ns ×T _n +F _ss ×T _dp to calculate the priority value of different frequency time slots, determine the final priority of each time slot of the selected frequency point value TP, select the time slot with the largest final priority value TP and configure it for the regular service, where T _dp is a parameter of the priority value of every time slot.

This step is used to realize the selection of the time slot resources of the selected frequency point. When the selected frequency point is the same as the frequency point used by the concurrent MBMS service, the time slot selection does not need to consider the concurrent UE capability limitation standard , and when the two are different, it is necessary to consider the concurrent UE capability limitation standard, that is, to meet the requirements of inter-frequency time slots. Therefore, it is necessary to calculate the priority value of inter-frequency time slots according to the formula TP=F _ns ×T _n +F _ss ×T _dp calculates the final priority value of each time slot.

Here, by introducing the parameter T _dp , the requirement of inter-frequency time slots in the concurrent UE capability limitation standard is transformed into a priority value parameter, so that the aforementioned two standards are considered comprehensively in the selection of inter-frequency time slots.

In practical application, when the idle time slot of the selected frequency point and the time slot used by the MBMS service do not satisfy the condition of time slot separation, the parameter T _dp is zero.

Embodiment 1 of the present invention will be further described below through resource configuration methods for conventional services implemented in two different application scenarios.

What the following scenarios have in common is that there are three frequency point resources in the cell, namely f1, f2, and f3. The uplink and downlink time slot configurations of each frequency point are the same, that is, TS0 is downlink, TS1, TS2 are uplink, and TS3, TS4, TS5, TS6 are downlink.

Scenario 1: After the UE has activated the MBMS service, it then requests to activate a regular service. The MBMS service occupies the time slot TS3 of frequency f1. The regular service is an Adaptive Multi-Rate (AMR) voice service. 2 code channels of the SF16 spread spectrum of the slot.

Assume that in scenario 1, each parameter used in the present invention is preset according to the idea of balancing each factor, and the specific settings are shown in Table 1:

parameter value F _ns 0.5 F _ss 0.5 _Psp 48 P _d When there is an idle time slot that satisfies the interval interval condition: 48 When there is no idle slot that meets the interval interval condition: 0 T _d When the time slot condition is met: 12 When the time slot condition is not met: 0

Table 1

The DCA frequency point/time slot selection standard adopted in this scenario is: the general priority value of each frequency point or time slot is its current number of idle code channels.

Assume that the current number of idle code channels in f1 is 72, which is the same frequency as the resources occupied by MBMS services; the number of idle code channels in f2 is 48, and TS5 is idle, and the resources occupied by MBMS services meet different frequency interval time slots; f3 is idle The number of code channels is 36, but both TS5 and TS6 have no free code channels, and resources occupied by MBMS services do not satisfy the time slots with different frequency intervals. For f1, the number of idle code channels of TS1 is 14, the number of idle code channels of TS2 is 16, the number of idle code channels of TS3 is 0, the number of idle code channels of TS4 is 16, the number of idle code channels of TS5 is 12, and the number of idle code channels of TS6 is The number of free code channels is 14. It should be noted that, in practical applications, when a time slot is the same as the time slot used by the MBMS service, the number of idle code channels on the time slot will be 0. Therefore, the number of idle code channels of TS3 in this embodiment is 0,

In Scenario 1, the specific implementation method of this embodiment is as follows:

According to DCA's frequency point/time slot selection standard, determine the general priority value of each frequency point:

The normal priority value S _n of f1 is 72; the normal priority value S _n of f2 is 48; the normal priority value S _n of f3 is 36;

Determine the final priority value of each frequency point:

The frequency point where f1 and the MBMS service are located is the same frequency, and the final priority value of f1 is calculated by using the same-frequency frequency point priority value calculation formula:

FP = F _ns × S _n + F _ss × P _sp = 0.5 × 72 + 0.5 × 48 = 60

The frequencies where f2 and the MBMS service are located are different frequencies, and there are idle time slots, and the final priority value of f2 is calculated by using the different frequency frequency priority value calculation formula:

FP = F _ns × S _n + F _ss × P _dp = 0.5 × 48 + 0.5 × 48 = 48

The frequency points where f3 and the MBMS service are located are different frequencies, but there is no idle time slot, therefore, _Pdp is zero, and the final priority value of f3 is calculated using the different frequency frequency point priority value calculation formula:

FP = F _ns × S _n + F _ss × P _dp = 0.5 × 36 + 0.5 × 0 = 18

Selecting the frequency point f1 corresponding to the largest final priority value 60 to be preferentially allocated to the AMR voice service;

For f1 frequency point, select the time slot:

According to the DCA frequency point/time slot selection standard, determine the general priority value of each time slot of f1:

The normal priority value of TS1 is 14, the normal priority value of TS2 is 16, the normal priority value of TS3 is 0, the normal priority value of TS4 is 16, the normal priority value of TS5 is 12, and the normal priority value of TS6 is 14.

Since f1 is the same frequency as the frequency point where the MBMS service is located, the time slot resource configured for the AMR voice service can be determined according to the above-mentioned common priority value, specifically as

For the uplink time slots TS1 and TS2, the TS2 with the highest final priority value is selected to be preferentially configured to the AMR voice service, and for the downlink time slots TS4, TS5, and TS6, the TS4 with the highest final priority value is selected to be preferentially configured for the AMR voice service.

To sum up, in Scenario 1, the AMR voice service is preferentially admitted on the f1 frequency point, where the uplink is preferentially admitted to TS2, and the downlink is preferentially admitted to TS4.

Scenario 2: The UE has activated the regular service, and then activates the MBMS service

Assuming that the regular service is an uplink 64K/downlink 64K PS service, this service occupies 8 SF16 spread spectrum code channels of TS4 at frequency f2, and the MBMS service is a 128K MBMS service, and the MBMS service occupies The resources are all code channels of TS3 at frequency point f1. At this time, the PS service and the MBMS service have different frequencies, but do not meet the concurrency requirements of different frequency and time slots (because TS3 and TS4 are adjacent), and because the service areas of the MBMS service all include multiple cells, it is impossible The resources occupied by the MBMS service are adjusted according to the resource conditions of one of the cells, so at this time only the resources occupied by the PS service in this cell can be adjusted to meet the concurrent service requirements. For the frequency point and time slot adjustment in this concurrent scenario, the same as the access of conventional services, it is also necessary to select the frequency point and time slot, so it is also necessary to implement resource configuration according to the present invention

Assume that in the second scenario, the parameters used in the present invention are preset according to the idea of focusing on different frequency interval time slots, and the specific settings are shown in Table 2:

parameter value F _ns 0.3 F _ss 0.7 _Psp 48 P _d When there is an idle time slot that satisfies the condition of every time slot: 62 When there is no free time slot that satisfies the condition of every time slot: 0 T _d When the time slot condition is met: 16 When the time slot condition is not met: 0

Table 2

The DCA frequency point/time slot selection standard adopted in this scenario is: the general priority value of each frequency point or time slot is its current number of idle code channels.

Assume that the current number of idle code channels of f1 is 72, which is the same frequency as the resource occupied by the MBMS service. The number of f2 idle code channels is 68, TS5 has idle code channels, and the resources occupied by MBMS service meet the different frequency interval time slots. The number of free code channels in f3 is 36, but neither TS5 nor TS6 has any free code channels, and resources occupied by MBMS services do not satisfy the time slots with different frequency intervals. For f2, the number of idle code channels for TS1 is 12, the number of idle code channels for TS2 is 14, the number of idle code channels for TS3 is 0, the number of idle code channels for TS4 is 16, the number of idle code channels for TS5 is 16, and the number of idle code channels for TS6 is 16. The number of free code channels is 10.

In the second scenario, the specific implementation method of this embodiment is as follows:

According to DCA's frequency point/time slot selection standard, determine the general priority value of each frequency point:

The normal priority value S _n of f1 is 72; the normal priority value S _n of f2 is 68; the normal priority value S _n of f3 is 36;

Determine the final priority value of each frequency point:

The frequency point f1 is the same frequency as the frequency point where the MBMS service is located, and the final priority value of f1 is calculated by using the same-frequency frequency point priority value calculation formula:

FP = F _ns × S _n + F _ss × P _sp = 0.3 × 72 + 0.7 × 48 = 55.2

The frequency point f2 is different from the frequency point where the MBMS service is located, and there is an idle time slot. The final priority value of f2 is calculated by using the formula for calculating the priority value of different frequency points:

FP = F _ns × S _n + F _ss × P _dp = 0.3 × 68 + 0.7 × 62 = 63.8

The frequency point f3 is different from the frequency point where the MBMS service is located, but there is no idle time slot, and the final priority value of f3 is calculated by using the formula for calculating the priority value of different frequency points:

FP = F _ns × S _n + F _ss × P _dp = 0.3 × 36 + 0.70 × 0 = 10.8

Determine the maximum value from the above-mentioned final priority values that have been determined to be 63.8, and configure the frequency point f2 corresponding to the maximum value to the AMR voice service; on the frequency point f2.

For frequency point f2, select the time slot:

According to the DCA frequency point/time slot selection standard, determine the general priority value of each time slot of f2:

The normal priority value of TS1 is 12, the normal priority value of TS2 is 14; the normal priority value of TS3 is 0, the normal priority value of TS4 is 16, the normal priority value of TS5 is 16, and the normal priority value of TS6 is 10.

Since the frequency point f2 is different from the frequency point occupied by the MBMS service, at this time, according to the calculation formula TP=F _ns ×T _n +F _ss ×T _dp of the priority value of different frequency time slots, determine the idle time points of the frequency point f2 The final priority value TP of the time slot:

For TS1, the final priority value is determined according to the formula for calculating the priority value of different frequency time slots:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 12 + 0.5 × 16 = 14

For TS2, because it does not meet the time slot condition, its T _dp is 0, and its final priority value is determined according to the calculation formula of different frequency time slot priority values:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 14 + 0.5 × 0 = 7

For TS3, because it does not meet the time slot condition, its T _dp is 0, and its final priority value is determined according to the calculation formula of the priority value of different frequency time slots:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 0 + 0.5 × 0 = 0

For TS4, because it does not meet the time slot condition, its T _dp is 0, and its final priority value is determined according to the calculation formula of the priority value of different frequency time slots:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 16 + 0.5 × 0 = 8

For TS5, since it satisfies the time slot condition, its T _dp is 16, and its final priority value is determined according to the calculation formula of different frequency time slot priority values:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 16 + 0.5 × 16 = 16

For TS6, since it satisfies the time slot condition, its T _dp is 16, and its final priority value is determined according to the calculation formula of different frequency time slot priority values:

TP = F _ns × T _n + F _ss × T _dp = 0.5 × 10 + 0.5 × 16 = 13

According to the final priority value of the above time slot, it can be determined that the final priority value of TS1 in the uplink time slot is the largest, and the final priority value of TS5 in the downlink time slot is the largest. Therefore, TS1 and TS5 are configured for the AMR voice service.

To sum up, in Scenario 2, the AMR voice service is preferentially admitted on the f2 frequency point, wherein the uplink is preferentially admitted to TS1, and the downlink is preferentially admitted to TS5.

The above only exemplifies the resource configuration methods in two concurrent scenarios. In addition to the above two scenarios, other concurrent scenarios as mentioned above can also use the resource configuration method of the present invention to configure conventional services in concurrent scenarios. This will not go into detail one by one.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
