Description

Resource allocation and service customization method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for resource allocation and service customization.

Background

Currently, in a User Equipment (UE) Service mechanism of a Long Term Evolution (LTE) system, when a UE performs a network subscription with a core network, a priority of the UE and a Quality of Service (QoS) of the UE are fixed, and when a network side performs resource allocation on the UE, an access network needs to perform resource allocation according to the Quality of Service of the UE when the network subscription with the core network is performed.

When the network side estimates the available resource of the UE, it needs to calculate the newly added resource of the UE according to the service quality information of the UE at the time of subscription, for example, Aggregate Maximum Bit Rate (AMBR) information of the UE, and combines the used resource of the cell to determine whether to provide the corresponding resource requirement for the UE.

However, as the UE service quality requirement becomes personalized, the service quality requirements of different UEs for services may be different, and the user may request the network side to subscribe to different service qualities through the UE according to personal preferences. If the UE requests to subscribe to the service and the subscription is successful, the network side needs to provide the UE with the quality of service of the UE requesting to subscribe to the service. That is to say, when different UEs subscribe to different service qualities, the service qualities required by the different UEs are also different, and specifically include the data transmission rate and the error rate of the service required by the UE, and the priority for allocating resources to the UE.

At present, when a network side allocates resources to a UE, priority division of radio bearers is performed according to the service type of the UE on the premise of fairness in radio resource allocation methods such as a time domain, a frequency domain, and a space domain, when there is a difference in a service applied by the UE, resource estimation is performed by a radio access network when estimating radio resources under the condition of meeting the requirements of service quality of all UEs during subscription and under the condition of resource usage information of a current cell, and resource estimation cannot be flexibly performed according to the usage condition of network resources and the requirements of service quality of the UE. Moreover, the resource scheduling algorithm is also based on the fairness of the service quality of all UEs, and specifically, on the basis of satisfying the basic service quality requirements of all UEs, if there are remaining wireless resources, the resource allocation is performed on the UE with the high priority, and it cannot be guaranteed that the resource allocated to the UE with the high priority remains unchanged.

In summary, in the prior art, the network side cannot allocate resources to the UE according to the service quality of the service requested to be customized by the UE and the service quality of the service provided by the network side for the UE, so that the network side cannot flexibly allocate resources, and cannot embody differentiated services of the UE.

Detailed Description

The resource allocation in the embodiment of the invention refers to that an access network allocates wireless resources to User Equipment (UE) after the UE requests to subscribe a service and subscribes successfully, wherein the access network in the embodiment of the invention refers to a wireless access network. The service subscription in the embodiment of the invention refers to the service subscription completed by the core network to the UE when the core network receives the service quality of the service subscribed by the UE request.

In the embodiment of the invention, when the service quality of the service requested to be customized by the UE is allocated to the UE, the wireless access network needs to estimate the wireless resource of the cell where the UE is located when receiving the service quality of the service requested to be customized and sent by the UE, and then the UE can be guaranteed to be allocated with enough wireless resource after the service requested to be customized by the UE is successfully customized so as to meet the service quality requirement of the service requested to be customized by the UE.

Referring to fig. 1, on an access network side, a resource allocation method provided in an embodiment of the present invention includes:

s101, receiving a UE resource estimation indication message for indicating an access network to estimate resources for User Equipment (UE);

the method comprises the steps of receiving UE resource pre-estimation indication information which is sent by UE or forwarded by a core network and is used for indicating an access network to pre-estimate resources for the UE. Specifically, the UE sends a UE resource pre-estimation indication message for indicating that the access network pre-estimates the resource for the UE to the access network, or the UE sends a UE resource pre-estimation indication message for indicating that the access network pre-estimates the resource for the UE to the core network, and the core network forwards the UE resource pre-estimation indication message for indicating that the access network pre-estimates the resource for the UE to the access network.

The resource estimation refers to calculating the service quality of a service that a cell where the UE is located can provide for the UE, that is, the first service quality.

S102, determining a first service quality according to the UE resource pre-estimation indication message, and sending the first service quality to a core network, wherein the first service quality is the service quality of a service which can be provided for the UE by a cell where the UE is located;

when the first service quality is determined according to the UE resource pre-estimation indication message, the cell where the UE is located needs to satisfy the first condition and the second condition:

the first condition is as follows: the number of the UE currently subscribing the service in the cell where the UE is located is smaller than a preset threshold K, the preset threshold K indicates that the cell where the UE is located can only provide service subscription service for K UEs at the same time, and the specific value of K can be determined according to actual needs;

and a second condition: the resource that the cell where the UE is located can allocate to the UE is larger than the resource occupied by the UE to satisfy the service requirement of the UE before requesting to subscribe to the service,

n% is an available resource modification factor, which is a preset constant, and a specific value may be determined according to actual needs, for example, 90% or 80%, and is used to modify the resource that can be allocated to the UE in the cell where the UE is located, but the preset constant is not limited to, for example, a numerical value;

if the cell where the UE is located meets the first condition and the second condition, determining a first service quality which can be provided for the UE by the cell where the UE is located according to the position of the UE, the capability of the UE, the interference suffered by the UE and the resource which can be allocated to the UE by the cell where the UE is located;

Specifically, the first quality of service includes a data transmission rate and an error rate of a service that the cell where the UE is located can provide for the UE. And the access network receives the broadband CQI information reported by the UE according to the calculated resources which can be allocated to the UE by the cell where the UE is located to obtain the possible MCS level of the UE, and determines the data transmission rate and the error rate of the service which can be provided by the access network for the UE. The calculation process is the same as the prior art and is not described in detail here.

The cell where the UE is located may allocate resources to the UE, including resources occupied by the specific UE and idle resources; wherein the specific UE is a UE other than a UE for which a bit rate service can be guaranteed, a UE for which a subscription service has been requested in the cell and subscription is successful, and a UE that can currently camp only in the cell.

Specifically, the idle resource described in the embodiment of the present invention refers to a remaining radio resource of a cell on the basis of satisfying the most basic service quality of all UE services. In the embodiment of the present invention, the total available resource of the cell in which the UE is located is idle resource + resource occupied by the UE for GBR service + resource occupied by the UE that has requested to subscribe to the service in the cell and subscribed successfully + resource occupied by the UE that can currently reside in the cell + resource occupied by the specific UE.

The UE currently residing in the cell only in the embodiment of the present invention includes UEs where the UE is located and cannot be redirected/switched to the neighboring cell or shunted to other small cells, the UE capability does not support UEs with load balancing values neighboring cells or shunted to other small cells, and the UE service attribute is not convenient for load balancing to the neighboring cell or cannot be shunted to other small cells.

S103, receiving a message which is sent by the core network and comprises a second service quality, wherein the second service quality is the first service quality or the service quality of a service which requests subscription for the UE;

s104, distributing resources for the UE according to the second service quality.

Wherein, step S104 specifically includes:

judging whether the cell can provide the second service quality for the UE according to the idle resources of the cell, and if so, allocating resources for the UE from the idle resources according to the second service quality;

The second quality of service is the first quality of service or the quality of service of the service requested to be subscribed by the UE, and is determined by the core network, and the specific process is described in detail at the core network side.

It should be noted that any quality of service in the embodiment of the present invention includes a data transmission rate and a bit error rate.

Accordingly, referring to fig. 2, at the core network side, a service subscribing method provided in an embodiment of the present invention includes:

s201, receiving the service quality of a service which is requested to be customized by User Equipment (UE);

and receiving the service quality of the service which is sent by the UE or forwarded by the access network and is requested to be subscribed by the UE.

S202, receiving a first service quality sent by an access network, wherein the first service quality is the service quality of a service which can be provided for User Equipment (UE) by a cell where the UE is located and is determined by the access network according to a UE resource estimation indication message for indicating the access network to estimate resources for the UE;

after receiving the service quality of the service requested to be subscribed by the user equipment UE, the core network sends a UE resource pre-estimation indication message for indicating the access network to pre-estimate resources for the user equipment UE to the access network, and then can receive the first service quality sent by the access network. And the first service quality is the service quality of the service which can be provided for the UE by the cell where the UE is located according to the UE resource estimation indication message for indicating the access network to estimate the resources for the UE.

S203, when determining that the service can be subscribed for the UE according to the first service quality and the service quality of the service requested to be subscribed by the UE, determining that a second service quality is the first service quality or the service quality of the service requested to be subscribed by the UE, and sending the second service quality to the access network.

Wherein determining the second quality of service comprises: when the first service quality is higher than or equal to the service quality of the service requested to be subscribed by the UE, determining the second service quality as the service quality of the service requested to be subscribed by the UE; and when the negotiation is successful, determining that the second service quality is the first service quality.

And when the negotiation fails, sending an indication message for indicating that the service subscription requested by the UE fails to be subscribed to the UE.

When it is determined that the service can be subscribed to for the UE according to the first quality of service and the quality of service of the service requested to be subscribed by the UE, the core network sends an indication message indicating that the service requested to be subscribed by the UE is successfully subscribed to the UE. The UE is informed that the service subscription is successful, so that the humanization of the service subscription process is improved.

Any of the qualities of service described in the embodiments of the present invention includes a data transmission rate and a bit error rate.

The following embodiments 1, 2, and 3 will describe in detail the resource allocation and service subscription method proposed in the embodiments of the present invention.

Assuming that the cell can provide customized service for K UEs at the same time, when the UE is not satisfied with the current basic service quality, for example: the UE wants to complete the downloading of a video, audio, novel in a short time, or load a mail and a web page at the same time, and then the UE sends the service quality of the service requested to be subscribed to the network side. The network side needs to complete the service requested to be subscribed by the UE according to the service quality of the service requested to be subscribed, and allocate the radio resource required by the UE.

Example 1

The specific processing flow comprises the following steps:

step one, the UE sends the service quality of the service requested to be customized by the UE and UE resource prediction indication information used for indicating an access network to predict resources for the UE of the user equipment to a core network, wherein the service quality of the service requested to be customized by the UE comprises information such as data transmission rate and bit error rate requested to be customized by the UE, cost of the service requested to be customized by the UE and the like.

And step two, after receiving a UE resource estimation indication message for indicating the access network to estimate resources for the user equipment UE, the core network sends the indication message to the access network.

And step three, after receiving the UE resource pre-estimation indication message, the access network performs resource pre-estimation on the resource of the cell where the UE is located, specifically, judges whether the cell where the UE is located meets the first preset condition and the second preset condition at the same time, if so, determines the service quality, namely the first service quality, of the service which can be provided for the UE by the cell where the UE is located, and sends the first service quality to the core network.

The resource estimation method comprises the following steps:

judging whether the cell where the UE is located meets a first condition and a second condition:

the first condition is as follows: the number of the UE of the current customized service of the cell where the UE is located is less than K;

and a second condition: the resource which can be allocated to the UE by the cell where the UE is located is more than the resource occupied by the UE before the UE requests to subscribe the service and meets the service requirement of the UE;

wherein, the resource occupied by the UE to satisfy the UE service requirement before the UE requests to subscribe the service is the resource occupied by the UE to satisfy the service quality when the UE subscribes with the network side.

The formula of the second condition is to ensure that the resources that can be allocated to the UE by the cell where the UE is located are sufficient to meet the service quality requested by the UE.

Specifically, the cell in which the UE is located may allocate the resource to the UE by N% (total available resource of the cell in which the UE is located-resource occupied by UE capable of guaranteeing bit rate service-resource occupied by UE that has requested to subscribe to service in the cell and is occupied by UE that has subscribed successfully-resource occupied by UE that can currently only be occupied by UE that resides in the cell);

wherein, N% is an available resource correction factor used for correcting the resource which can be allocated to the UE in the cell where the UE is located; for example, N% may be 90% or N% may be 80%, and the value of N% may be set by the cell. The cell where the UE is located may allocate resources to the UE, including resources occupied by a specific UE and idle resources; wherein the specific UE is a UE other than a UE for which a bit rate service can be guaranteed, a UE for which a subscription service has been requested in the cell and subscription is successful, and a UE that can currently camp only in the cell.

Specifically, when the cell in which the UE is located satisfies the first condition and the second condition, determining a first quality of service that the cell in which the UE is located can provide for the UE according to the location of the UE and/or the capability of the UE and/or interference suffered by the UE, and resources that the cell in which the UE is located can allocate to the UE, where the first quality of service specifically includes one or a combination of the following manners:

the first method is as follows: and determining that the UE is positioned at the edge position or the center position of the cell according to the position information of the UE, and then determining the first service quality. For example, if the UE starts an interference cancellation algorithm and is located in the center of the cell, the calculated resource that the cell where the UE is located can allocate to the UE is allocated to the UE according to the second condition; if the UE starts the interference cancellation algorithm and is located at the edge of the cell, a part of the calculated resources that the cell where the UE is located can allocate to the UE is allocated to the UE according to the second condition, for example, 50% of the calculated resources that the cell where the UE is located can allocate to the UE may be allocated to the UE, and finally, the first quality of service is determined.

The second method comprises the following steps: and determining the model of the UE and the configuration of the UE according to the capability of the UE, wherein the configuration of the UE comprises the application layer capability of the UE, the size of a terminal buffer area, the size of a screen and the like, and after calculating resources which can be allocated to the UE by a cell where the UE is located according to a second condition, the access network determines the first service quality according to the configuration of the UE. For example, the first quality of service cannot exceed the capability of the UE, otherwise, resources are wasted, for example, it is calculated that the data transmission rate that the cell where the UE is located can allocate to the UE is K1 bits/sec, but the UE can only support K2 bits/sec, and K2 < K1, then the data transmission rate in the first quality of service estimated by the access network is K2 bits/sec.

The third method comprises the following steps: according to the interference suffered by the UE, the access network can acquire the resource occupation condition of the adjacent cell and estimate the first service quality which can be provided for the UE by the cell where the UE is located. For example, the cell where the UE is located may obtain the resource occupation condition of the neighboring cell according to the X2 interface, and when the occupation of some resources by the neighboring cell causes interference to the resource usage of the cell, remove the resource causing the interference, and then determine the maximum transmission rate that the cell where the UE is located can provide for the UE.

The access network receives the wideband CQI information reported by the UE according to the calculated resources which can be allocated to the UE by the cell where the UE is located to obtain the possible MCS level of the UE, and determines the data transmission rate and the error rate of the service which can be provided by the access network for the UE. The calculation process is the same as the prior art and is not described in detail here.

Step four, the core network receives the first service quality sent by the access network, then carries out the service subscription of the UE according to the received service quality of the service which the UE requests to subscribe and the first service quality, determines the second service quality after the subscription is successful, and sends the second service quality to the access network. Otherwise, after the subscription fails, sending an indication message for indicating that the service subscription requested by the UE is successful to the UE.

Specifically, when the first service quality is higher than or equal to the service quality of the service requested to be subscribed by the UE, the service requested to be subscribed by the UE completes subscription, so that the core network determines that the second service quality is the service quality of the service requested to be subscribed by the UE; when the first service quality is lower than the service quality of the service requested to be subscribed by the UE, the first service quality is negotiated with the UE, the core network sends the first service quality as the request information of the service quality of the service requested to be subscribed by the UE to the UE, and if the UE feeds back the agreement, the negotiation is successful, and the core network determines that the second service quality is the first service quality.

And if the UE rejects the feedback, the negotiation fails, and the core network sends an indication message for indicating that the service subscription requested by the UE fails to be subscribed to the UE.

And the second service quality also comprises the priority of the UE resource allocation determined by the core network according to the received cost of the service which the UE requests to subscribe. The priority of the UE resource allocation means that the network side allocates resources for the UE in the order of the priority from high to low.

Step five, the access network receives the second service quality sent by the core network, and then performs resource allocation to the UE according to the second service quality, the priority allocated to the UE resource by the UE request subscription, and the idle resource.

Specifically, after receiving the second quality of service sent by the core network and the priority of resource allocation of the UE, the access network allocates resources to the UE in the order from high priority to low priority. The specific process is as follows:

in order to guarantee the service quality of the service requested to be subscribed by the UE with high priority, the access network preferentially allocates resources to the UE with high priority, and allocates the resources under the condition that the UE is guaranteed to be absolutely preferential.

For example, for a UE with a high priority, the resource allocation principle is: judging whether the idle resources of the cell where the UE is located meet the requirement of providing second service quality for the UE, if so, distributing the idle resources of the cell where the UE is located to the UE according to the second service quality under the condition of ensuring the priority of the distributed resources of the UE;

if the cell in which the UE is located cannot meet the requirement of providing the second quality of service for the UE, the specific UE in the cell in which the UE is located needs to be transferred, and then idle resources are counted again until the counted idle resources meet the requirement of providing the second quality of service for the UE, and the idle resources in the cell in which the UE is located are allocated to the UE according to the second quality of service, wherein the specific UE is a UE other than a UE capable of guaranteeing a bit rate service, a UE that has requested to subscribe to a service in the cell and has subscribed successfully, and a UE that can currently only reside in the cell. Stated differently, a particular UE refers to a UE that is capable of handover.

The idle resources described in the embodiments of the present invention refer to the remaining radio resources of a cell on the basis of satisfying the most basic service quality of all UE services. The resources that the cell in which the UE is located may be allocated to the UE include resources occupied by a specific UE and idle resources. That is, the resources that can be allocated to the UE obtained in step three > idle resources.

Wherein, the process of transferring the specific UE to the adjacent cell is as follows:

(a) if a low-load small cell exists under the coverage of a macro cell where the UE requesting to subscribe the service exists, transferring at least one specific UE to the low-load small cell until idle resources of the cell where the UE requesting to subscribe the service exists meet the service quality requested to be subscribed by the UE, wherein the specific UE can be non-guaranteed bit rate (NGBR) service; otherwise, performing step (b).

(b) If the macro cell where the UE requesting to subscribe to the service exists in the same or partially same coverage inter-frequency cell or inter-system cell with lower load, then at least one specific UE may be switched or redirected to the corresponding inter-frequency cell or inter-system cell until the idle resources of the cell where the UE requesting to subscribe to the service exists satisfy the quality of service of the service requested to be subscribed by the UE; otherwise, step c) is performed.

(c) If there are neighboring cells with low load around the macro cell, a specific UE, such as a UE located at a cell edge, may be handed over to the neighboring cell until the idle resources of the cell where the UE requesting to subscribe to the service is located satisfy the quality of service of the service requested to be subscribed by the UE.

So that the service subscribed by the UE requesting subscription is successful and the resource required to be allocated by the UE is allocated.

The whole processing flow comprises the following steps:

step one, the UE sends the service quality of the service requested to be customized by the UE and UE resource pre-estimation indication information used for indicating the access network to pre-estimate resources for the UE, wherein the service quality of the service requested to be customized by the UE comprises the data transmission rate and the bit error rate requested to be customized by the UE and the cost of the service requested to be customized by the UE.

Step two, the access network sends the service quality of the service requested to be customized by the UE to a core network, and performs resource pre-estimation on the resource of the cell where the UE is located according to the received UE resource pre-estimation indication message for indicating the access network to pre-estimate the resource for the UE, specifically, judges whether the cell where the UE is located meets the first and second preset conditions at the same time, if so, determines the service quality of the service which can be provided for the UE by the cell where the UE is located, namely, the first service quality, and sends the first service quality to the core network.

Step three, the core network receives the first service quality sent by the access network, then carries out service subscription of the UE according to the received service quality of the service which the UE requests to subscribe and the first service quality, determines the second service quality after the subscription is successful, and sends the second service quality to the access network. Otherwise, after the subscription fails, sending an indication message for indicating that the service subscription requested by the UE is successful to the UE.

Step four, the access network receives the second service quality sent by the core network, and then performs resource allocation to the UE according to the second service quality, the priority allocated to the UE resource by the UE request subscription, and the idle resource.

Wherein, the calculation processes of the second, third and fourth steps are the same as the corresponding calculation process of the embodiment 1, and are not repeated here.
