Description

Method and device for determining establishment of air interface bearer

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining establishment of an air interface bearer.

Background

In a Long Term Evolution (LTE) system, only broadcast Services are supported by a Vehicle-to-event (V2X) promissory service, and a service model thereof is based on each Packet of data, that is, an application layer packages service data, divides the service data into packets and transmits the packets to an access layer, and simultaneously carries a Priority/Reliability (PPPP/R) of each Packet of short-range service of the Packet.

For convenience of description, referring to fig. 1, a communication link between a User Equipment 1 (UE 1) and a UE2 is defined as a direct communication link (Sidelink, SL), a corresponding radio interface of which is referred to as an SL interface, and a communication link between an eNodeB and the UE is defined as a cellular communication link (uulink, UL), and a corresponding interface of which is referred to as a Uu interface. For a New air interface (NR) of 5G, a V2X service explicitly supports broadcast, multicast, and unicast services, an original congestion control mechanism based on a Channel congestion Ratio (CBR) only controls a data packet, and there is no operation criterion based on establishment or release of an air interface bearer. In addition, in order to reflect the channel congestion situation, the LTE system establishes different mapping tables from CBR to transmission parameters for different PPPP/rs, and through the mapping tables, LTE can control parameters such as the maximum transmission power of each data packet at the air interface.

However, when the channel is congested, in the CBR-based adjustment mechanism for the transmission parameters of the data packets, a new service may still access the channel and may send the data packets to the air interface, which may not alleviate the congestion condition of the channel, and increases the system load and resource consumption.

Therefore, it is necessary to design a method for determining establishment of an air interface bearer to solve the above problem.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In this embodiment of the present invention, when the UE is located within the coverage of the base station, the base station notifies the UE of the channel congestion status and a QoS set that allows to establish an air interface bearer or a mapping relationship between channel congestion thresholds through a broadcast or a dedicated signaling, for example, the dedicated signaling may be a Radio Resource Control (RRC) signaling, a Media Access Control (MAC) signaling, or a physical layer signaling, and if the UE has new data to send and the UE is in an RRC connected state, the base station determines whether to establish the air interface bearer for the new data according to the mapping relationship and a corresponding criterion. When the UE is out of the coverage range of the base station, the UE obtains the mapping relation between the channel congestion condition and the QoS set or channel congestion threshold allowed to establish air interface bearing through pre-configuration. In addition, if the UE has new data to send and is in an RRC IDLE (IDLE) or INACTIVE (INACTIVE) state, the UE obtains a mapping relationship from a channel congestion status to a QoS service list allowing bearer establishment according to a System Information Block (SIB) or a dedicated signaling, and then determines whether the QoS of the new data is in the allowed list, and further determines whether to establish an air interface bearer for the new data.

For convenience of description, in the embodiments of the present invention, in consideration of the situation that the UE is in an RRC IDLE or INACTIVE state and the UE is located outside the coverage of the base station, the UE receives information broadcast by the base station or obtains a related mapping relationship through pre-configuration, and then detects a channel and a service condition by the UE itself, so as to establish an air interface bearer.

Referring to fig. 2, in the embodiment of the present invention, a determination process for establishing an air interface bearer is as follows:

step 200: the UE receives first information sent by a base station, wherein the first information at least comprises a target channel condition parameter, a target service level and a plurality of channel condition ranges, and one channel condition range corresponds to one service level set.

Specifically, in the embodiment of the present invention, when the UE is in an RRC connected state, an RRC IDLE state, or an INACTIVE state, the base station may broadcast the first information to the UE, so that the UE receives the first information sent by the base station through an SIB or an RRC signaling, or when the UE is located outside a coverage area of the base station, the UE may pre-configure the first information and obtain at least information such as a target channel condition parameter, a target service level, and a plurality of channel condition ranges from the first information, where one channel condition range corresponds to one service level set, and in addition, the plurality of channel condition ranges may be obtained by dividing according to a plurality of channel condition threshold values included in the first information.

The channel parameters at least comprise any one or more of a through interface received signal strength indicator (S-RSSI), a through interface received signal power (S-RSRP), a through interface discovery channel received signal power (SD-RSRP) and a target channel congestion ratio (CBR), and the service grades at least comprise any one or more of a through interface service quality sequence number (PQI), a service resource type parameter, a data packet error rate, a data stream bit rate and a service quality (QoS) grade.

For example, the target channel condition parameter may be represented by a target CBR, the target traffic class may be represented by a target QoS class, and the channel condition range may be represented by a CBR range, then one CBR range corresponds to one QoS class set.

Step 210: if the target channel condition parameter belongs to a first channel condition range in the plurality of channel condition ranges, the UE judges whether the target service level belongs to a first service level set corresponding to the first channel condition range.

Specifically, in the embodiment of the present invention, after obtaining the target channel condition parameter and the plurality of channel condition ranges from the first information, the UE determines whether the target channel condition parameter belongs to a first channel condition range of the plurality of channel condition ranges, and if the target channel condition parameter belongs to the first channel condition range of the plurality of channel condition ranges, the UE further determines whether the target service class belongs to a first service class set corresponding to the first channel condition range.

For example, when the target channel condition parameter is a target CBR and the target service class is a target QoS class, the UE needs to determine whether the target CBR belongs to a first CBR range of the CBR ranges and determine whether the target QoS class belongs to a first QoS class set corresponding to the first CBR range.

Step 220: and if the target service level belongs to the first service level set, the UE determines to establish an air interface bearer for the target service corresponding to the first information.

Specifically, in the embodiment of the present invention, when determining that the target service level belongs to the first service level set according to the relationship between the target service level and the first service level set, the UE determines to establish an air interface bearer for the target service corresponding to the first information.

Specifically, in the process of determining to establish an air interface bearer, when the target channel parameter is greater than or equal to a second threshold and is less than or equal to a first threshold, that is, when the target channel condition parameter is not greater than the first threshold and is not less than the second threshold, the UE determines whether the target service level is greater than a service level threshold included in the first information, where the first threshold is greater than the second threshold, and if the target service level is greater than the service level threshold, the UE determines to establish the air interface bearer for the new service. When the target channel condition parameter is greater than a first threshold value, judging whether the service level of the existing service is smaller than the target service level, if the service level of the existing service is smaller than the target service level, judging whether the ARP indicates that the existing service is allowed to be preempted, if the ARP indicates that the existing service is allowed to be preempted, releasing an air interface bearer of the existing service, and establishing an air interface bearer for the target service corresponding to the first information.

For example, before determining to establish an air interface bearer for the new service, the UE needs to first determine that the target QoS class belongs to the first QoS class, then compare the target QoS class with the QoS threshold according to the size relationship between the target CBR and the first CBR threshold, or further determine the preemption characteristics of the existing service according to the size relationship between the QoS class of the existing service and the target service QoS class, and then establish the air interface bearer according to the determination results of various conditions.

Referring to fig. 3, in the embodiment of the present invention, when the target channel condition parameter is represented by the target CBR, the target traffic class is represented by the target QoS class, the channel condition range may be represented as a CBR range, the first information comprising a plurality of CBR threshold values, there may be a plurality of CBR ranges obtained by dividing according to the CBR threshold value, and in the embodiment of the present invention, assuming that the plurality of CBR threshold values in the first information includes at least a first CBR threshold value and a second CBR threshold value, the CBR ranges can be obtained by dividing according to the CBR threshold values, and therefore, the CBR ranges at least include a first CBR range, a second CBR range, and a third CBR range, the first CBR range, the second CBR range, and the third CBR range are respectively provided with a first QoS class set, a second QoS class set, and a third QoS class set, and a first detailed flow of the establishment determination of the air interface bearer is as follows:

step 300: the UE receives first information sent by the base station.

Specifically, in the embodiment of the present invention, when the UE is in an RRC IDLE state or an INACTIVE state, the base station may broadcast the first information to the UE, so that the UE receives the first information sent by the base station through an SIB or RRC signaling, or when the UE is located outside a coverage area of the base station, the UE may pre-configure the first information, where the first information at least includes a target CBR, a target QoS class, a target service class, and a plurality of CBR ranges, and one CBR range corresponds to one QoS class set.

Step 301: the UE determines whether the target CBR in the first information belongs to a first CBR range of the CBR ranges, if so, performs step 302, otherwise, performs step 303.

Specifically, in the embodiment of the present invention, the UE obtains the plurality of CBR ranges by dividing according to the plurality of CBR threshold values, where the first information includes the plurality of CBR threshold values, that is, a range in which the CBR is greater than the first CBR threshold value is divided into a first CBR range, a range in which the CBR is not greater than the first CBR threshold value and is not less than the second CBR threshold value is divided into a second CBR range, and a range in which the CBR is less than the second CBR threshold value is divided into a third CBR range.

Therefore, in this embodiment of the present invention, after receiving the first information sent by the base station or pre-configuring the first information, the UE may obtain a target CBR from the first information, then compare the target CBR with the first CBR threshold and the second CBR threshold, first determine whether the target CBR is greater than the first CBR threshold, that is, determine whether the target CBR belongs to a first CBR range of the CBR ranges, if the target CBR belongs to the first CBR range of the CBR ranges, execute step 302, otherwise, execute step 303.

For example, when the first CBR threshold value (th1) is 0.5 and the second CBR threshold value (th2) is 0.25, that is, when th1 is 0.5 and th2 is 0.25, the target CBR is compared with th1 and th2, respectively, and first, it is determined whether the target CBR is greater than th1, that is, whether the target CBR belongs to the first CBR range divided by th 1.

Step 302: the UE determines whether the target QoS class belongs to the first QoS class set corresponding to the first CBR range, if so, performs step 307, otherwise, performs step 308.

Specifically, in this embodiment of the present invention, when the UE determines that the target CBR is greater than the first CBR threshold value, that is, when it determines that the target CBR belongs to a first CBR range of the CBR ranges, the UE further determines whether the target QoS class belongs to a first QoS class set, where the first QoS class set corresponds to the first CBR range, if the target QoS class belongs to the first QoS class set corresponding to the first CBR range, step 307 is executed, otherwise, step 308 is executed. For example, when the target CBR is 0.7 and th1 is 0.5, since 0.7>0.5, the UE determines that the target CBR belongs to the first CBR range, and then determines whether the target QoS class belongs to the first QoS class set.

Step 303: the UE determines whether the target CBR belongs to the second CBR range, if yes, go to step 304, otherwise, go to step 305.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR is not greater than the first CBR threshold, the UE further determines whether the target CBR belongs to a second CBR range, that is, the UE determines whether the target CBR is greater than or equal to a second threshold, and the target channel parameter is less than or equal to a first threshold, that is, the target CBR is not greater than the first CBR threshold, and the target CBR is not less than the second CBR threshold, if the target CBR belongs to the second CBR range, step 304 is executed, otherwise, step 305 is executed.

Step 304: the UE determines whether the target QoS class belongs to the second QoS class set, if yes, step 307 is executed, otherwise, step 308 is executed.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to the second CBR range, the UE further determines whether the target QoS class belongs to the second QoS class set corresponding to the second CBR range, if the target QoS class belongs to the second QoS class set corresponding to the first CBR range, step 307 is executed, otherwise, step 308 is executed.

Step 305: the UE determines that the target QoS class belongs to the third CBR range.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR does not belong to the first CBR range and the second CBR range, the UE further determines that the target QoS class belongs to the third CBR range, that is, the UE determines that the target CBR is smaller than the second CBR threshold value.

Step 306: the UE determines whether the target QoS class belongs to the third QoS class set, if yes, step 307 is executed, otherwise, step 308 is executed.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to the third CBR range, the UE further determines whether the target QoS class belongs to a third QoS class set corresponding to the third CBR range, if the target QoS class belongs to the third QoS class set corresponding to the third CBR range, step 307 is executed, otherwise, step 308 is executed.

Step 307: and the UE establishes an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to the first CBR range and the target QoS class belongs to the first QoS class set, or when the UE determines that the target CBR belongs to the second range and the target QoS class belongs to the second QoS class set, or when the target CBR belongs to the third CBR range and the target QoS class belongs to the third QoS class set, the UE allows an air interface bearer to be established for the target service.

Step 308: the UE does not need to establish an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, when the UE determines that the target service QoS class does not belong to the first QoS class set corresponding to the first CBR range, or determines that the target service QoS class does not belong to the second QoS class set corresponding to the second CBR range, or determines that the target service QoS class does not belong to the third QoS class set corresponding to the third CBR range, the UE is not allowed to establish an air interface bearer for the target service, that is, the UE does not need to establish an air interface bearer for the target service.

Step 309: and the UE finishes the establishment judgment flow of the air interface bearer.

Specifically, in the embodiment of the present invention, after completing the procedure of determining to establish an air interface bearer according to the first information, the UE determines to establish the air interface bearer for the target service, or determines to end the procedure of determining to establish the air interface bearer this time when determining that the air interface bearer does not need to be established for the target service.

Referring to fig. 4, in the embodiment of the present invention, when the target channel condition parameter is represented by a target CBR and the target service level is represented by a target QoS level, it is assumed that the CBR threshold values in the first information at least include a first CBR threshold value and a second CBR threshold value, the CBR ranges at least include a first CBR range, a second CBR range, and a third CBR range, the first CBR range, the second CBR range, and the third CBR range respectively correspond to the first QoS level set, the second QoS level set, and the third QoS level set, and the QoS threshold value (QoSth) is further included in the first information, a second detailed flow of the establishment decision of the idle port bearer is as follows:

step 400: the UE receives first information sent by the base station.

Specifically, in the embodiment of the present invention, the UE receives first information sent by the base station through SIB or RRC signaling, or when the UE is located outside the coverage area of the base station, the UE may pre-configure the first information, where the first information at least includes a target CBR, a target QoS level, a QoSth, and several CBR ranges, and one CBR range corresponds to one QoS level set.

Step 401: the UE determines whether the target CBR belongs to the first CBR range, if yes, step 406 is performed, otherwise, step 402 is performed.

Specifically, in the embodiment of the present invention, the UE determines whether the target CBR belongs to a first CBR range of the CBR ranges, if the target CBR belongs to the first CBR range of the CBR ranges, step 406 is executed, otherwise, step 402 is executed.

Step 402: the UE determines whether the target CBR belongs to the second CBR range, if yes, go to step 403, otherwise, go to step 404.

Step 403: the UE determines whether the target QoS level is greater than the QoS threshold, if so, performs step 405, otherwise, performs step 406.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to a second CBR range of the CBR ranges and the target QoS class belongs to a second QoS class set corresponding to the second CBR range, further determining whether the new service QoS class is greater than a QoS threshold, if the target QoS class is greater than the QoS threshold, executing step 405, otherwise, executing step 406.

Step 404: the UE determines that the target QoS class belongs to the third CBR range.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR does not belong to the first CBR range and does not belong to the second CBR range, the UE determines that the target QoS class belongs to the third CBR range, that is, the UE determines that the target CBR is smaller than the second threshold.

Step 405: and the UE establishes an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, the UE determines that the target QoS class is greater than the QoS threshold in the second CBR range, or determines that the target QoS class belongs to the third CBR range, and since the third QoS class set corresponding to the third CBR range includes all QoS classes, the target QoS class of any target service belongs to the first QoS class set, that is, the channel condition at this time is particularly good, a new service can be accessed, and an air interface bearer is allowed to be established for the target service.

Step 406: the UE does not need to establish an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to a first CBR range of the CBR ranges, because a first QoS class set corresponding to the first CBR range is an empty set at this time, the target QoS class does not belong to the first QoS class set, and therefore an air interface bearer is not established, that is, a channel at this time is very congested, and all new services are not allowed to be accessed. In addition, when the UE determines that the QoS level of the target service is not greater than the QoS threshold, the UE does not allow an air interface bearer to be established for the target service, that is, the UE does not need to establish an air interface bearer for the target service.

Step 407: and the UE finishes the establishment judgment flow of the air interface bearer.

Referring to fig. 5, in the embodiment of the present invention, it is assumed that the plurality of CBR threshold values in the first information at least include a first CBR threshold value and a second CBR threshold value, the plurality of CBR ranges at least include a first CBR range, a second CBR range, and a third CBR range, the first CBR range, the second CBR range, and the third CBR range respectively correspond to the first QoS class set, the second QoS class set, and the third QoS class set, and the first information further includes QoSth and Allocation preemption level (ARP), a third detailed flow of the establishment determination of the air interface bearer is as follows:

step 500: the UE receives first information sent by the base station.

Specifically, in the embodiment of the present invention, the UE receives first information sent by the base station through SIB or RRC signaling, or when the UE is located outside the coverage area of the base station, the UE may pre-configure the first information, where the first information at least includes a target CBR, a target QoS level, QoSth, ARP, and a plurality of CBR ranges, and one CBR range corresponds to one QoS level set.

Step 501: the UE determines whether the target CBR belongs to the first CBR range, if yes, step 505 is performed, otherwise, step 502 is performed.

Specifically, in the embodiment of the present invention, the UE determines whether the target CBR belongs to a first CBR range of the CBR ranges, if the target CBR belongs to the first CBR range of the CBR ranges, step 505 is executed, otherwise, step 502 is executed.

Step 502: the UE determines whether the target CBR belongs to the second CBR range, if yes, step 503 is executed, otherwise, step 504 is executed.

Step 503: the UE determines whether the target QoS level is greater than the QoS threshold, if so, performs step 508, otherwise, performs step 509.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to a second CBR range of the CBR ranges and the target QoS class belongs to a second QoS class set corresponding to the second CBR range, further determining whether the target service QoS class is greater than a QoS threshold, if the target QoS class is greater than the QoS threshold, executing step 508, otherwise, executing step 509.

Step 504: the UE determines that the target QoS class belongs to the third CBR range.

Step 505: the UE determines whether the QoS class of the existing service is less than the target QoS class, if so, performs step 506, otherwise, performs step 509.

Specifically, in the embodiment of the present invention, when the UE determines that the target CBR belongs to a first CBR range of the CBR ranges and the target QoS class belongs to a first QoS class set corresponding to the first CBR range, or when the UE determines that the target QoS class is greater than a QoS threshold value in a second range, the UE further determines whether the QoS class of the existing service is less than the target QoS class, if the QoS class of the existing service is less than the target QoS class, step 506 is executed, otherwise, step 509 is executed.

Step 506: the UE determines whether the ARP indicates that the existing service is allowed to be preempted, if so, performs step 507, otherwise, performs step 509.

Specifically, in the embodiment of the present invention, when determining that the QoS level of the existing service is less than the target QoS level, the UE further determines whether the ARP indicates that the existing service is allowed to be preempted, if the ARP indicates that the existing service is allowed to be preempted, step 507 is executed, otherwise, step 509 is executed.

Step 507: and the UE releases the air interface bearer of the existing service.

That is, the UE determines that the QoS level of the existing service is less than the target QoS level, and releases the air interface bearer of the existing service when the ARP indicates that the existing service is allowed to be preempted.

Step 508: and the UE establishes an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, the UE determines to release an air interface bearer for the existing service, or determines that the target QoS class belongs to a third CBR range, and since a third QoS class set corresponding to the third CBR range includes all QoS classes, the target QoS class of any target service belongs to the first QoS class set, that is, the channel condition at this time is particularly good, and all new services can be accessed, the air interface bearer is allowed to be established for the target service.

Step 509: the UE does not need to establish an air interface bearer for the target service.

Specifically, in the embodiment of the present invention, the UE determines that the QoS level of the existing service is less than the target QoS level, or determines whether the ARP indicates that the existing service is allowed to be preempted, or determines that the target service QoS level is not greater than the QoS threshold, and the UE does not allow to establish an air interface bearer for the target service, that is, the UE does not need to establish an air interface bearer for the target service.
