Description

Resource allocation method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a resource allocation method and device.

Background

When User Equipment (UE) sends uplink data, the UE requests a base station to allocate resources to the UE, and then the UE allocates resources to a plurality of logical channels of the UE for the UE to send the uplink data.

Generally, the UE may allocate resources to a plurality of logical channels between the UE and the base station, specifically, the UE may allocate resources according to configuration parameters of the plurality of logical channels, and the configuration parameters of the logical channels may include priorities and Prioritized Bit Rates (PBRs) of the logical channels, for example, the UE may allocate resources, which satisfy the PBRs of the plurality of logical channels, to the plurality of logical channels respectively according to an order from a high priority to a low priority of the logical channels. Illustratively, it is assumed that there are 4 logical channels (including logical channel 1, logical channel 2, logical channel 3, and logical channel 4) between the UE and the base station, where priority of logical channel 1 > priority of logical channel 2 > priority of logical channel 3 > priority of logical channel 4, where priority of logical channel 1 > priority of logical channel 2, which means that priority of logical channel 1 is higher than priority of logical channel 2, and if PBRs of the 4 logical channels are the same, they are all 10-bit mb/s; assuming that the base station configures 100Mbit of resources for the UE, the UE may allocate 10Mbit of resources to the 4 logical channels in sequence according to the priority of the logical channels.

The concept of network slice is introduced in a 5G network, wherein one network slice may include one or more logical channels, for example, network slice 1 may include the above logical channel 1, logical channel 2, and logical channel 3, and network slice 2 may include the above logical channel 4. If there are remaining resources after allocating resources to the plurality of logical channels according to the priorities of the logical channels, the UE continues to allocate the remaining resources to all or part of the logical channels in the plurality of logical channels according to the priorities of the logical channels, for example, after the 4 logical channels are respectively allocated with 10Mbit resources (i.e., the 4 logical channels are allocated with 40Mbit resources in total), 60Mbit resources still remain, and the UE may allocate all the 60Mbit resources to the logical channel with the highest priority, i.e., logical channel 1. At this time, a logical channel 1 is allocated with 70Mbit of resources, and logical channels 2, 3, and 4 are allocated with 10Mbit of resources, that is, a network slice 1 is allocated with 90Mbit of resources, and a network slice 2 is allocated with 10Mbit of resources.

Assuming that the target rate of the network slice 1 is 50Mbit/s (the amount of resources required for transmitting data in a unit time), the target rate of the network slice 2 is 30Mbit/s, the allocated resources (90Mbit) of the network slice 1 are greater than the resources consumed by the network slice 1 in a unit time, and the allocated resources (10Mbit) of the network slice 2 are less than the resources consumed by the network slice 2 in a unit time, it is obvious that the above method of allocating resources according to the priority of the logical channel and the PBR of the logical channel does not match the rate requirement of the network slice (for example, the allocated resources of the network slice 2 are less than the target rate of the network slice 2), so that the resource allocation is not reasonable, and the efficiency of data transmission is affected.

The input unit 24 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 24 may include a touch screen 241 and other input devices 242. The touch screen 241, also called a touch panel, can collect touch operations of a user (such as operations of the user on or near the touch screen 241 using any suitable object or accessory, such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch screen 241 may include two parts, a touch detection device and a touch controller.

In one aspect, the audio circuit 26 may transmit the converted electrical signal of the received audio data to the speaker 261, and the converted electrical signal is converted into a sound signal by the speaker 261 and output. On the other hand, the microphone 262 converts the collected sound signals into electrical signals, which are received by the audio circuit 26 and converted into audio data, which are then output by the processor 20 to the RF circuit 21 for transmission to, for example, another cellular phone, or output by the processor 20 to the memory 23 for further processing.

With reference to the communication system shown in fig. 2, the following fully describes the resource allocation method provided in the embodiment of the present invention from the perspective of interaction between the UE and a network device (e.g., a base station) in the communication system, so as to describe a process in which the UE acquires network slice configuration information and logical channel configuration information, and a process in which the UE allocates resources to one or more logical channels of the UE according to the network slice configuration information and the logical channel configuration information.

As shown in fig. 5, a resource allocation method provided in an embodiment of the present invention may include S101 to S105:

s101, the network equipment determines network slice configuration information and logic channel configuration information.

Wherein the network slice configuration information includes configuration information of a plurality of network slices for providing services for the UE, and the configuration information of one network slice includes one of the following items: the priority of the network slice, the rated speed of the network slice, the resource proportion of the network slice or the time delay indication information of the network slice; the configuration information of the logical channel includes priorities of the logical channels of the UE and PBRs of the logical channels.

It should be understood that, in the above network slice configuration information, the priority of a network slice is an index that reflects the requirement of the network slice on the transmission rate, the delay, and the like, and a higher priority of a network slice indicates that the requirement of the network slice on the transmission rate, the delay, and the like is higher, that is, a higher rate or a lower delay is required; the rated speed of the network slice is an ideal speed corresponding to the network slice or a target speed signed with an operator (for example, the rated speed of the network slice 1 is 50 Mbit/s); the resource proportion of the network slice refers to the proportion of the resource occupied by each network slice (for example, for 3 network slices, the resource proportion of the network slice 1 is 50%, the resource proportion of the network slice 2 is 30%, and the resource proportion of the network slice 3 is 20%); the time delay indication information of the network slice is used for indicating the time delay of obtaining the network slice and allocating resources to the network slice according to the time delay of the network slice, and the time delay of the network slice refers to the time delay from the last scheduling to the current scheduling of the network slice.

Similarly, the priority of the logical channel in the logical channel configuration information may be an index that represents the requirement of the logical channel for rate or delay, and is not described in detail here.

It should be noted that, in the embodiment of the present invention, the priority size corresponding to the numerical value of the priority (including the priority of the network slice and the priority of the logical channel) is not specifically limited. Specifically, a larger value of the priority may indicate a higher priority (e.g., a value of the priority of network slice 1 is 1, a value of the priority of network slice 2 is 2, and a priority of network slice 2 is higher than a priority of network slice 1), and a smaller value of the priority may also indicate a higher priority (e.g., a value of the priority of network slice 1 is 1, a value of the priority of network slice 2 is 2, and a priority of network slice 1 is higher than a priority of network slice 2).

S102, the network equipment sends network slice configuration information and logic channel configuration information to the UE.

The network slice configuration information and the logical channel configuration information are used for the UE to allocate resources for one or more logical channels of the UE.

Optionally, the network device configures (i.e., sends) the network slice configuration information and the logical channel configuration information for the UE through Radio Resource Control (RRC) signaling.

S103, the UE receives the network slice configuration information and the logic channel configuration information sent by the network equipment.

S104, the UE allocates resources for one or more logic channels of the UE from the resources allocated for the UE by the network equipment according to the logic channel configuration information.

In connection with the description of the above embodiments, it should be understood that the logical channel configuration information includes respective priorities of a plurality of logical channels of the UE and respective PBRs of the plurality of logical channels, and the UE may allocate resources for one or more logical channels of the UE according to the respective priorities of the plurality of logical channels and the respective PBRs of the plurality of logical channels.

With reference to fig. 5, as shown in fig. 6, in an implementation manner, the S104 specifically includes S104a-S104 b:

s104a, the UE determines one or more logical channels of the multiple logical channels of the UE that satisfy a preset condition.

The preset condition is that the number of tokens which can be used in the current token bucket of the logical channel is greater than or equal to zero.

It can be understood that, in a plurality of logical channels of the UE, each logical channel corresponds to a variable, that is, the number of tokens that can be used in the current token bucket of the logical channel (hereinafter, denoted by Bj of the logical channel).

For example, assuming that Bj of logical channels 2, 3 and 5 is greater than or equal to zero and Bj of logical channels 1 and 4 is less than zero in the 5 logical channels shown in fig. 2, the UE may determine that logical channels 2, 3 and 5 are logical channels satisfying the predetermined condition.

S104b, the UE allocates resources for the one or more logical channels according to their respective priorities and their respective PBRs.

In the embodiment of the invention, the UE allocates the resources meeting the PBR of one or more logical channels according to the sequence of the priorities of the one or more logical channels from high to low.

With reference to the example in S104a, it is assumed that the priorities of the 5 logical channels are logical channel 1, logical channel 2, logical channel 3, logical channel 4, and logical channel 5 in order from high to low, the logical channels satisfying the preset condition (that is, Bj is greater than or equal to zero) are logical channel 2, logical channel 3, and logical channel 5, where PBR of logical channel 2 is 20Mbit/S, PBR of logical channel 3 is 10Mbit/S, PBR of logical channel 5 is 20Mbit/S, and the size of the resource to be allocated is 100Mbit, and the UE allocates resources of 20Mbit, 10Mbit, and 20Mbit to logical channel 2, logical channel 3, and logical channel 5 in order from high to low according to the priorities of the logical channels.

It should be understood that in the early stage of logical channel setup, Bj of one logical channel is 0 (i.e., initialization value); the UE will increase the resource amount corresponding to the PBR of the logical channel for the logical channel in each resource update period (the resource update period is T), and last for a plurality of resource update periods.

When the UE allocates resources for the logical channel this time, firstly, the Bj of the logical channel needs to be updated to obtain Bj ', and then, whether the resources are allocated for the logical channel is determined according to the Bj ' (that is, the resources are allocated for the logical channel of which Bj ' is greater than or equal to zero); then after allocating the resource for the logical channel, updating Bj' to obtain Bj ", and taking the updated Bj" as the Bj of the logical channel when the resource is allocated next time.

Here, for a logical channel, the method for updating Bj of the logical channel to obtain Bj' includes: bj ═ PBR × T + Bj, where T is used to indicate the duration of the interval from the last update Bj to this update Bj; the method for updating the Bj 'of the logical channel to obtain Bj' comprises the following steps: bj ═ Bj' -R, R indicates the resource size allocated to the logical channel by the UE this time (the resource size may also be characterized by the Service Data Unit (SDU) packet size).

It is understood that each logical channel also has its corresponding token bucket, and the capacity of the token bucket represents the maximum value of the resource amount that the logical channel can currently possess, in the embodiment of the present invention, Bj of a logical channel should be less than or equal to the capacity of the token bucket of the logical channel, where the capacity of the token bucket of a logical channel is equal to the product of PBR of the logical channel and the token bucket duration (BSD) of the logical channel (i.e., the capacity of the token bucket is equal to PBR × BSD).

For example, assuming that the initialization Bj of the logical channel 1 is 0, before the first time the resource is allocated to the logical channel 1, Bj of the logical channel 1 is updated to Bj ', according to the above update formula, Bj' is 40Mbit (assuming that T is 4 and PBR is 10); when the logical channel 1 is allocated with resources for the first time, the logical channel 1 is allocated with resources of 140Mbit (i.e., R ═ 140), then Bj' of the logical channel 1 is updated to Bj ″, where Bj ″ -100 Mbit; when the resource is allocated to the logical channel 1 for the second time, the Bj "(i.e., -100Mbit) is set as the Bj of the logical channel 1 when the resource is allocated to the logical channel 1 for the second time.

It should be understood that before allocating resources for the logical channel 1 for the second time, Bj of the logical channel 1 is updated from Bj to Bj 'again through the above update formula, and assuming that the resource update period, i.e. PBR of the logical channel 1 is not changed (i.e. T is 4, PBR is 10Mbit/s), Bj' is-100 Mbit +40Mbit is-60 Mbit; at this time, Bj' is less than zero, which indicates that excessive resources are allocated when the logical channel 1 is allocated for the first time, and when resources are allocated for the second time, the embodiment of the present invention preferentially considers allocating resources for other logical channels (i.e., logical channels where Bj is greater than or equal to zero), so as to improve the rationality of resource allocation.

In this embodiment of the present invention, after the UE allocates resources for the first or multiple logical channels of the UE, the following S105 is executed:

and S105, under the condition that the network equipment has residual resources in the resources configured for the UE, the UE allocates resources for one or more logic channels of the UE from the residual resources according to the network slice configuration information.

For convenience of description, in the following embodiments, after completing the above S104, the resources that are still remaining in the resources configured for the UE by the network device (i.e., the remaining resources in S105) are each referred to as a first remaining resource.

With reference to the foregoing description of the embodiments, it should be understood that, after the UE allocates resources for one or more logical channels according to its logical channel configuration information, if there are remaining resources in the resources allocated to the UE by the network device (i.e. a first remaining resource, for example, the resource to be allocated in S104b is 100Mbit, a resource of 50Mbit has been allocated in S104b, and a resource of 50Mbit remains), the UE allocates the first remaining resource to one or more logical channels of the UE according to the network slice configuration information.

With reference to fig. 6, as shown in fig. 7, in an implementation manner, when the network slice configuration information is the priority of the network slice, S105 specifically includes S105 a:

s105, the UE allocates the remaining resources to one or more logical channels of the UE according to the priorities of the plurality of network slices and the priorities of the plurality of logical channels, 105 a.

In the embodiment of the present invention, the UE determines, according to the priorities of multiple network slices, an order of resource allocation (that is, it is determined that resources are allocated to a network slice with a high priority first and then resources are allocated to a network slice with a low priority), and allocating resources to a network slice specifically means allocating resources to one or more logical channels included in the network slice according to the priorities of the logical channels included in the network slice and respective required resource amounts of the logical channels (it can be understood that the required resource amounts are cached in a buffer of each logical channel).

Referring to fig. 2, assuming that the network slice 2 has a higher priority than the network slice 1, the UE allocates the first remaining resource to the network slice 2 preferentially, and if there are more remaining resources to be reallocated to the network slice 1, until the first remaining resource is allocated. The allocating resources for the network slice 2 from the first remaining resources specifically includes: resources are allocated to one or more of the logical channels (including logical channel 4 and logical channel 5) included in the network slice 2 according to the priorities of the logical channels in the network slice 2, since the priority of logical channel 4 is higher than the priority of logical channel 5 in network slice 2, the UE can first allocate resources for logical channel 4 in network slice 2, after allocating resources for the logical channel 4, if there are remaining resources, allocating resources for the logical channel 5, so that the UE completes resource allocation to the network slice 2, after the UE allocates resources to the network slice 2, if there are remaining resources, then allocates resources to the logical channels included in the network slice 1, and the method for the UE to allocate resources to the network slice 1 is similar to the method for the UE to allocate resources to the network slice 2, which is not described herein again.

In one case, after S104, when the amount of the first remaining resources is less than or equal to the amount of resources required by the highest priority logical channel in the highest priority network slice, the UE allocates all the first remaining resources to the highest priority logical channel. For example, in another assumption, if the logical channel 4 needs 50Mbit of resources, the UE allocates all of the first remaining resources (i.e., 50Mbit of remaining resources) to the logical channel 4.

In the embodiment of the invention, the network equipment configures the priority of the network slice for the UE, so that the UE can allocate resources for the logic channel of the UE by combining the priority of the network slice, and the rationality of resource allocation is improved.

Referring to fig. 6, as shown in fig. 8, in an implementation, when the network slice configuration information is a rated rate of the network slice, S105 specifically includes S105 b:

s105b, the UE allocates resources for one or more logical channels of the UE from the rest resources according to the rated rates of the network slices and the priorities of the logical channels.

In conjunction with the description of the foregoing embodiment, it should be understood that each network slice in the multiple network slices of the UE corresponds to a rated rate, and the rated rate is an ideal rate corresponding to the network slice or a target rate subscribed by an operator, and in an embodiment of the present invention, the rated rate of the network slice may be expressed by a Slice Bit Rate (SBR).

In the embodiment of the present invention, the UE determines the order of resource allocation according to the rated rates of the multiple network slices (i.e. it is determined that resources are allocated to the network slice with the high rated rate first, and then resources are allocated to the network slice with the low rated rate), and allocating resources to the network slice specifically means allocating resources to one or more logical channels included in the network slice according to the priority of the logical channels of the network slice and the amount of resources required by the logical channels.

It is understood that the UE may allocate resources for the logical channels included in the multiple network slices from the remaining resources (i.e., the first remaining resources) in order of the rated rates of the multiple network slices from large to small, so that the network slices with high requirements on the rates are preferentially guaranteed to be allocated to the resources. The resources may also be allocated to the logical channels included in the multiple network slices from the remaining resources (i.e., the first remaining resources) in the order from the smaller rated rates of the multiple network slices to the larger rated rates of the multiple network slices, so that it can be ensured that more network slices (or logical channels) are allocated to appropriate resources, and the specific allocation manner is determined according to actual needs, which is not specifically limited in the embodiments of the present invention.

Specifically, taking a network slice as an example, the UE first determines a target allocated resource amount of the network slice, where the target allocated resource amount is equal to a difference between a resource amount corresponding to a rated rate of the network slice and a resource amount already allocated to the network slice, and where the resource amount already allocated to the network slice is equal to a sum of resource amounts already allocated to a plurality of logical channels included in the network slice; then UE judges whether the resource quantity actually needed by the network slice is smaller than the target allocation resource quantity of the network slice, wherein the resource quantity actually needed by the network slice is equal to the sum of the resource quantities needed by a plurality of logic channels contained in the network slice; if the actually required resource amount of the network slice is smaller than the target resource allocation amount of the network slice, the UE allocates the actually required resource amount for the network slice; otherwise, the UE allocates the target allocation resource amount corresponding to the network slice.

Illustratively, in conjunction with fig. 2 and the example in S104b described above, it is assumed that the rated rate of network slice 1 is 50Mbit/S and the rated rate of network slice 2 is 30Mbit/S, so that the UE preferentially allocates resources to network slice 1 and reallocates to network slice 2 if there are remaining resources after allocating resources to network slice 1. Assuming that the resources already allocated to each of the logical channel 1, the logical channel 2, and the logical channel 3 in the network slice 1 are 0Mbit, 10Mbit, and 20Mbit, it is known that the target allocated resource amount of the network slice 1 is 20 Mbit. Further, assuming that the amount of resources actually required by the network slice 1 is 10Mbit (i.e., the sum of the amounts of resources required by the logical channels 1, 2, and 3 in the network slice 1 is 10Mbit), since the amount of resources actually required by the network slice 1 (10Mbit) is less than the target allocated resource amount (20Mbit) of the network slice 1, the UE allocates the 10Mbit of resources in the first remaining resources (i.e., 50Mbit of resources) to the network slice 1, specifically, in the network slice 1, the UE allocates the resources according to the priorities of the plurality of logical channels (i.e., logical channel 1, logical channel 2, and logical channel 3) in the network slice 1 and the amounts of resources required by the plurality of logical channels; if the amount of resources actually required by the network slice 1 is 20Mbit, the UE allocates the 20Mbit resources of the first remaining resources to the network slice 1.

Similarly, if there are remaining resources after the resources are allocated to the network slice 1, then resources are allocated to the multiple logical channels (i.e. the logical channel 4 and the logical channel 5) of the network slice 2, specifically, a method for allocating resources to the multiple logical channels of the network slice 2 by the UE is similar to the method for allocating resources to the multiple logical channels of the network slice 1 by the UE, and is not described herein again.

In conjunction with the description of the above embodiments, it should be understood that after the network slice 1 and the network slice 2 are allocated with the first remaining resources according to the rated rate of the network slice and the priority of the logical channels (i.e., after S105 b), there may be remaining resources (hereinafter referred to as second remaining resources), and at this time, the UE may allocate resources for one or more logical channels of the UE again from the second remaining resources according to the priority of the logical channels of the UE, and at this time, the configuration information of the network slice does not need to be considered.

Illustratively, in combination with the above example, after the UE allocates 20Mbit of the first remaining resources to the network slice 1 and 10Mbit of the first remaining resources to the network slice 2, there still exists 30Mbit of second remaining resources, and then the UE allocates the second remaining resources to one or more logical channels according to the priorities of the 5 logical channels of the UE and the respective required resource amounts of the 5 logical channels, specifically, the UE first allocates resources to the logical channel 1, if the required resource amount of the logical channel 1 is 0 at this moment, the UE continues to allocate resources to the logical channel 2, and so on until the second remaining resources are allocated.

In the embodiment of the present invention, the UE allocates resources to the logical channels included in the multiple network slices from the remaining resources according to the sequence of the rated rates of the multiple network slices from large to small (i.e., allocates resources to a network slice with a large rated rate preferentially, and then allocates resources to a network slice with a small rated rate), so that the transmission rate of a network slice with a large rated rate can be ensured, and the user experience of a large client (or a client with a higher requirement on the transmission rate of the network slice) can be improved.

Similarly, the method for the UE to allocate resources to the logical channels included in the multiple network slices from the remaining resources according to the descending order of the rated rates of the multiple network slices is similar to the method for the UE to allocate resources to the logical channels included in the multiple network slices from the remaining resources according to the descending order of the rated rates of the multiple network slices, and is not described herein again. The UE allocates resources for the logical channels contained in the network slices from the remaining resources according to the sequence of the rated rates of the network slices from small to large (namely, the resources are allocated preferentially to the network slices with small rated rates and then allocated to the network slices with large rated rates), and under the condition that the network slices are more, the transmission rates of more network slices can be ensured, and the transmission practicability of the network slices is improved.

With reference to fig. 6, as shown in fig. 9, in an implementation manner, when the network slice configuration information is a resource proportion of the network slice, S105 specifically includes S105 c:

s105c, the UE allocates resources for one or more logical channels of the UE from the residual resources according to the resource occupation ratios of the network slices and the priorities of the logical channels.

In conjunction with the description of the above embodiments, it should be understood that the resource occupation ratio of the network slice refers to the proportion of the resource occupied by each network slice. Specifically, taking a network slice as an example, the UE first determines an amount of resources to be allocated of the network slice, where the amount of resources to be allocated is equal to a product of remaining resources (i.e., first remaining resources) and a resource proportion of the network slice; then, the UE determines whether the amount of resources actually required by the network slice is less than the amount of resources to be allocated to the network slice, where the amount of resources actually required by the network slice is equal to the sum of the amounts of resources required by a plurality of logical channels included in the network slice (it can be understood that the amount of resources required by each logical channel is cached in the buffer); if the resource amount actually required by the network slice is less than the resource amount which should be allocated to the network slice, the UE only allocates the resource amount actually required by the network slice; otherwise, the UE allocates the corresponding resource amount to the network slice.

Illustratively, in conjunction with fig. 2 and the example in S104b described above, assuming that the resource occupancy of the network slice 1 is 50% and the resource occupancy of the network slice 2 is 30%, since the first remaining resource is 50Mbit, it can be known that the amount of resources to be allocated for the network slice 1 is 25Mbit and the amount of resources to be allocated for the network slice 2 is 15 Mbit. Further, assuming that the amount of resources actually required by the network slice 1 is 20Mbit (i.e., the sum of the amounts of resources required by the logical channels 1, 2, and 3 in the network slice 1 is 20Mbit), since the amount of resources (20Mbit) actually required by the network slice 1 is less than the amount of resources (25Mbit) to be allocated by the network slice 1, the UE allocates the 20Mbit of resources in the first remaining resources (i.e., the 50Mbit of resources) to the network slice 1, specifically, in the network slice 1, the UE allocates the resources according to the priorities of the plurality of logical channels (i.e., the logical channel 1, the logical channel 2, and the logical channel 3) in the network slice 1 and the amounts of resources required by the plurality of logical channels; if the amount of resources actually required by the network slice 1 is 25Mbit, the UE allocates 25Mbit of the resources of the first remaining resources to the network slice 1.

Similarly, if there are remaining resources after the resources are allocated to the network slice 1, then resources are allocated to the multiple logical channels (i.e., the logical channel 4 and the logical channel 5) of the network slice 2, specifically, a method for the UE to allocate resources to the multiple logical channels of the network slice 2 is similar to the method for the UE to allocate resources to the multiple logical channels of the network slice 1, and details are not repeated here.

With reference to the foregoing description of the embodiment, it should be understood that, after allocating the first remaining resources to the network slice 1 and the network slice 2 according to the resource proportion of the network slice and the priority of the logical channels (i.e., after S105 c), there may be remaining resources (hereinafter referred to as second remaining resources), at this time, the UE may allocate resources to one or more logical channels of the UE from the second remaining resources according to the priority of the logical channels of the UE, at this time, the configuration information of the network slice does not need to be considered.

Illustratively, in combination with the above example, after the UE allocates 25Mbit of resources in the first remaining resources to the network slice 1 and 15Mbit of resources in the first remaining resources to the network slice 2, there still exists 10Mbit of third remaining resources, then the UE allocates the second remaining resources to one or more logical channels according to the priority of 5 logical channels of the UE and the amount of resources required by each of the 5 logical channels, specifically, the UE first allocates resources for the logical channel 1, and if the amount of resources required by the logical channel 1 at this time is 10Mbit, the UE may allocate all the 10Mbit of second remaining resources to the logical channel 1; if the amount of resources required for the logical channel 1 is 0 at this time, the UE continues to allocate resources for the logical channel 2, and so on until the second remaining resources are allocated.

In the embodiment of the invention, the network equipment configures the resource ratio of the network slice for the UE, so that the UE can allocate resources for the logic channel of the UE by combining the resource ratio of the network slice, and the rationality of resource allocation is improved.

With reference to fig. 6, as shown in fig. 10, in an implementation manner, when the network slice configuration information is latency indication information of a network slice, S105 specifically includes S105d-S105 e:

s105, 105d, the UE obtains the time delay of a plurality of network slices according to the time delay indication information of the network slices.

With reference to the description of the foregoing embodiment, it should be understood that the delay of one network slice is used to indicate the delay from the last scheduling to the current scheduling of the network slice, and if the delay of the network slice 1 is greater than the delay of the network slice 2, it may be understood that, in the process of transmitting the service data, the time interval for acquiring the service data through the network slice 1 is greater than the time interval for acquiring the service data through the network slice 2.

S105e, the UE allocates the remaining resources to one or more logical channels of the UE according to the time delays of the multiple network slices and the priorities of the multiple logical channels.

In the embodiment of the present invention, the UE determines the order of resource allocation according to the time delay of multiple network slices (that is, first allocating resources to a network slice with a large time delay and then allocating resources to a network slice with a small time delay), and allocating resources to a network slice specifically means allocating resources to one or more logical channels included in the network slice according to the priority of the logical channels included in the network slice and the amount of resources respectively required by the logical channels (the amount of resources required by each logical channel is cached in a buffer).

Referring to fig. 2, assuming that the delay of network slice 2 is greater than the delay of network slice 1, the UE allocates the first remaining resource to network slice 2 preferentially, and if there are remaining resources to be reallocated to network slice 1, until the first remaining resource is allocated completely. The allocating resources for the network slice 2 from the first remaining resources specifically includes: resources are allocated to one or more of the logical channels (including logical channel 4 and logical channel 5) included in the network slice 2 according to the priorities of the logical channels in the network slice 2, since the priority of logical channel 4 is higher than the priority of logical channel 5 in network slice 2, the UE can first allocate resources for logical channel 4 in network slice 2, after allocating resources for the logical channel 4, if there are remaining resources, allocating resources for the logical channel 5, so that the UE completes resource allocation for the network slice 2, after the UE allocates resources to the network slice 2, if there are remaining resources, then allocates resources to the logical channels included in the network slice 1, and the method for the UE to allocate resources to the network slice 1 is similar to the method for the UE to allocate resources to the network slice 2, which is not described herein again.

In one case, after S104, when the amount of the first remaining resources is less than or equal to the amount of resources required by the logical channel with the highest priority in the network slice with the largest delay, the UE allocates all of the first remaining resources to the logical channel with the highest priority. For example, in another assumption, if the logical channel 4 needs 50Mbit of resources, the UE allocates all the first remaining resources (i.e. 50Mbit of remaining resources) to the logical channel 4.

In the embodiment of the invention, the network equipment configures the time delay indication information of the network slice for the UE, so that the UE can acquire the time delay of the network slice, and further allocates resources for the logic channel of the UE by combining the time delay of the network slice, thereby improving the rationality of resource allocation.

In an implementation manner of the embodiment of the present invention, a delay switch state of a network slice may also be set; after receiving the delay indication information of the network slice, the UE may obtain the delay of a part of the network slice (i.e., the network slice with the delay switch of the network slice in the on state) according to the delay indication information of the network slice, and further allocate resources to the part of the network slice.

For example, if the UE obtains the delay of the network slice 1 and the delay of the network slice 2 according to the delay indication information of 3 network slices (including the network slice 1, the network slice 2, and the network slice 3) (that is, the delay switch states of the network slice 1 and the network slice 2 are on, and the delay switch state of the network slice 3 is off), the UE may allocate the first remaining resource to the network slice 1 and the network slice 2.

According to the method example, the functional modules of the UE, the network device, and the like may be divided, for example, the functional modules may be divided corresponding to the functions, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, the division of the modules in the embodiment of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.

In the case of dividing the functional modules according to the respective functions, fig. 11 shows a possible structural diagram of the UE involved in the foregoing embodiment, as shown in fig. 11, the UE 40 may include: a receiving module 401 and a resource allocation module 402.
