Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.
In the description of the embodiments of the present invention, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of networks refers to two or more networks.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.
The UE in the embodiment of the invention can be an intelligent mobile terminal. The intelligent mobile terminal is a mobile terminal with an operating system. The intelligent mobile terminal can be: the smart mobile terminal may be a terminal device such as a smart phone, a tablet pc, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a smart watch, and a smart band, or the smart mobile terminal may be another type of smart mobile terminal.
The network architecture diagram of the resource allocation method provided by the embodiment of the present invention, as shown in fig. 1, includes: one or more UE, evolved UMTS Terrestrial Radio Access Network (E-UTRAN), core Network (Evolved Packet Core (EPC)) and operator's Network. The Evolved Packet System (EPS) can be connected to other access networks (not shown).
The E-UTRAN includes Evolved Node B (eNB) eNodeB and other eNodeBs, and may further include Multicast Coordination Entity (MCE). An eNodeB may be connected with other enodebs through a backhaul (e.g., X2 interface). The MCE may allocate time-frequency radio resources for Multimedia Broadcast Multicast service (eMBMS), and determine a radio configuration (e.g., MCS) for the eMBMS. The MCE may be an entity separate from the eNodeB or may be part of the eNodeB.
The eNodeB provides access for the UE to the EPC, to which the eNodeB is connected. The EPC may include a Mobility Management function (MME), a Home Subscriber Server (HSS), other MMEs, a Serving GateWay (SGW), a Multimedia Broadcast Service GateWay (MBMS-GW), a Broadcast Multicast Service Center (BM-SC), and a Public Data Network GateWay (PGW). The MME is a control node that handles signaling between the UE and the EPC, providing bearer and connection management. All user IP packets are sent through the SGW, and the SGW is connected with the PGW. The PGW provides UE IP address assignment as well as other functions. The PGW and BM-SC are connected to IP services, which may include Internet, intranet (intranet), IP Multimedia Subsystem (IMS), packet-switched streaming service (PSS), and/or other IP services. The BM-SC may serve the functions of location and delivery for MBMS users. The BM-SC may be used as an entry for content provider MBMS transmission, may be used in a Public Land Mobile Network (PLMN) to authorize and initiate an MBMS bearer service, and may also be used to schedule and transmit MBMS transmission. The MBMS-GW may be used as an eNodeB for distributing MBMS services to a Multicast/Multicast Single Frequency Network (MBSFN) area belonging to a Broadcast specific service, and may also be used for call back management (start/stop) and collecting eMBMS-related charging information.
The UE can perform signal communication via a Long Term Evolution (LTE) network and a millimeter wave (mmW) system. Thus, the UE may communicate with the eNodeB and/or other enodebs over the LTE link. In addition, the communication can also be performed with other Connection Points (CP) or base stations through mmW links.
In the prior art, when a UE accesses an Access Point Name (APN) of a certain network, a default bearer needs to be established. According to the protocol, the default bearer is a Non-Guaranteed Bit Rate (Non-Guaranteed Bit Rate, abbreviated as Non-GBR) bearer, and resources required by the bearer are allocated in a best effort manner, which is usually difficult to always meet the Rate requirement of the service when the network is busy.
Corresponding to Non-GBR, there is also a Guaranteed Bit Rate (GBR) bearer, which is usually established when a user initiates some specific service. The GBR bearer is configured with a minimum guaranteed rate (GBR) parameter, and in the GBR bearer establishing process, if network resources do not meet GBR requirements, the GBR bearer can be refused to be admitted; if the network resource meets the GBR requirement, the network allocates special resource for the GBR during the survival period of the bearer, and the GBR requirement of the bearer is ensured. GBR bearers are typically prioritized over Non-GBR bearers, and are mostly used for traffic with a steady bandwidth resource demand.
With the increase of network load and the increase of competition, operators have the need of subdividing customers and carrying out hierarchical guarantee for different user groups for the purpose of network fine operation. The existing 4G network establishes Non-GBR class default bearers for users of different grades respectively, but hardly guarantees the quality of Non-GBR class bearer services (only guarantees an extremely low bit rate, generally PBR =8kbps to 32 kbps). In order to solve the above problem, in the resource allocation method provided in the embodiments of the present invention, the base station may determine the priority bit rate and the priority guaranteed rate of each UE by obtaining the default bearer priority of each UE performing the Non-GBR bearer service in the coverage area; and further determining resource reservation of each UE in each user level according to at least two of the current resource residue, the priority bit rate, the priority guaranteed rate and the service rate, so that the user experience of the UE in each user level can be ensured.
For example, the user classes are described as an example, where the user classes include a first class and a second class, where the first class is an important user, the second class is an ordinary user, and the priority of the first class is higher than that of the second class, and a specific implementation process is as follows:
example one
An embodiment of the present invention provides a resource allocation method, as shown in fig. 2 and fig. 3, including:
s101, a base station acquires a user level, a default bearer priority and a service rate of the Non-GBR bearer service of each UE carrying out the Non-GBR bearer service in a coverage area.
It should be noted that, in practical applications, the user class and the default bearer (Non-GBR) priority of each UE may be configured in the core network through a user classification policy; therefore, when the UE initiates a Non-GBR bearer service request, the core network feeds back the user level and the default bearer priority of the UE to the base station according to the Non-GBR bearer service request of the UE, so that the base station can know the user level and the default bearer priority of each UE performing the Non-GBR bearer service in the coverage range.
It should be noted that the user classes correspond to the default bearer priorities one to one, and the higher the user class is, the higher the default bearer priority is.
For example, it is assumed that the user classes include a first class and a second class, where when the priority of the first class is higher than that of the second class, the default bearer priority corresponding to the first class is also higher than that corresponding to the second class.
S102, the base station determines a Priority Bit Rate (PBR) and a priority Guaranteed Rate (PGBR) of each UE according to the default bearer priority.
It should be noted that, in practical applications, for Non-GBR bearers of different priorities, PBRs may be defined, which are similar to minimum guaranteed rates in GBR bearers, and are used to calculate minimum guaranteed rates required by the Non-GBR bearers in an admission control process, and preferentially allocate resources to perform PBR rate guarantee in a scheduling process.
For Non-GBR bearers, the PBR bandwidth is usually only used to transmit important exchange signaling information for maintaining bearer connections, so as to meet the requirement of maintaining basic connections, and avoid the problem that a high-priority logical channel always occupies a large amount of resources, which results in connection loss and the like of a low-priority logical channel due to the fact that resources cannot be obtained.
The PGBR is used for resource scheduling, and can realize differentiated services of the network to different user levels on the premise of not influencing user admission control.
Specifically, on the base station side, the required PBR (typically 8kbps, 16kbps, or 32 kbps) and PGBR (which may be configured to have relatively high rate values such as 500kbps and 1mbps according to the user level) are respectively set corresponding to different default bearer priorities.
Illustratively, the PBRs in each user class in the base station are all set to 8kbps, while the PGBRs of the important users may be uniformly set to 500kbps, and the PGBRs of the normal users may be uniformly set to 0.
Or,
the PBR in each user class in the base station is set to 8kbps, the PGBR of the important user configures a rate value according to the user class determined by the actual grade division of the operator (for example, the A user and the B user are both important users, but the user class of the A user determined by the actual grade division of the operator is the Nth grade, the user class of the B user determined by the actual grade division of the operator is the N-1 th grade, and the priority of the Nth grade is higher than that of the N-1 th grade, so the PGBR of the A user can be set to 1mbps, and the PGBR of the B user can be set to 500 kbps), and the PGBR of the common user can be uniformly set to 0.
Specifically, when the a subscriber is upgraded from the normal subscriber to the important subscriber, the PGBR of the a subscriber is not 0 any more at this time, but is determined according to the ranking of the a subscriber.
Specifically, when the users are all normal users, since the PGBR of a normal user is 0, the user level has no proportional relationship with the PGBR.
S103, the base station determines resource reservation of each UE in each user level according to at least two of current resource residue, a priority bit rate, a priority guarantee rate and a service rate; wherein, the resource reservation corresponding to different user grades is different.
Optionally, the user rating includes a first rating and a second rating; wherein the first level comprises a user;
the base station determines resource reservation of each UE in each user class according to at least two of current resource residue, a priority bit rate, a priority guaranteed rate, and a service rate, as shown in fig. 3, 4, 5, and 6, including:
s1030, when the base station determines that the current resource residue is less than the sum of the service rates, if the current resource residue is greater than or equal to the service rate of the designated UE corresponding to the highest default bearer priority and the service rate of the designated UE is greater than the priority guaranteed rate of the designated UE, determining the resource reservation of the UE in the first class as Z according to the current resource residue, the priority bit rate and the priority guaranteed rate 1 The resource reservation of each UE in the second level is Z 2 ；

Wherein,

Wherein,
Z 1 ＝W-(N-1)×P 2 ；
Z 2 ＝P 2 ；
wherein, P 1 Indicating a priority guaranteed rate, P, for a given UE 2 Indicating a priority bit rate, P 3 The method comprises the steps of representing service rate, W representing current resource residue, N representing the total number of UE carrying out Non-GBR bearing service in a coverage range, and N being an integer larger than 1.
Specifically, in practical application, the method further includes:
s1033, when the base station determines that the current resource residue is less than the sum of the service rates, if the current resource residue is less than the service rate of the designated UE corresponding to the highest default bearer priority and the service rate of the designated UE is less than or equal to the priority guaranteed rate of the designated UE, determining the resource reservation of the UE in the first level to be Z according to the current resource residue and the priority bit rate 1 The resource reservation of each UE in the second level is Z 2 ；
Wherein,
Z 1 ＝W-(N-1)×P 2 ；
Z 2 ＝P 2 ；
wherein, P 2 Indicating a priority bit rate, W indicating a current resource remaining, N indicating a total number of UEs performing Non-GBR bearer service within a coverage area, and N being an integer greater than 1.
For example, suppose that there are three users, i.e., a user a, a user B, and a user C, in a cell coverage of 4G, where the user a is an important user, and the user B and the user C are both normal users. Three users, namely the user A, the user B and the user C, are all carrying out Non-GBR type bearer services, wherein the services carried out by the user A, the user B and the user C all need 600 kbps. If the cell only has the current resource of 600kbps left at the moment and PBR =8kbps and pgbr =500kbps, at this moment, the base station determines that the current resource left (600 kbps) is less than the sum of the traffic rates (600kbps +600kbps = 1800kbps), and if the current resource left (600 kbps) is greater than or equal to the traffic rate (600 kbps) of the designated UE (a user) corresponding to the highest default bearer priority and the traffic rate (600 kbps) of the designated UE is greater than the priority guarantee rate (500 kbps) of the designated UE, then the method is based on the principle that
Figure BDA0002225841010000101
The resource reservation distributed by the base station for the three users, namely the user A, the user B and the user C, can be determined as shown in the table 1, so that differentiated rate guarantee service of the network to the users of different levels can be realized on the premise of not influencing the access control of the users, and the proportional fairness is also considered.

For example, under a coverage area of a 4G cell, there are three users, i.e., user a, user B, and user C, where user a is an important user, and user B and user C are both normal users. Three users, namely the user A, the user B and the user C, are all carrying out Non-GBR type bearer services, wherein the services carried out by the user A, the user B and the user C all need 450kbps rate. If the cell only has the current resource of 600kbps left at the moment and PBR =8kbps and PGBR =500kbps, and the base station determines that the current resource left (600 kbps) is less than the sum of the service rates (450kbps +450kbps = 1350kbps), if the current resource left (600 kbps) is greater than or equal to the service rate (450 kbps) of the designated UE (A user) corresponding to the highest default bearer priority and the service rate (450 kbps) of the designated UE is less than or equal to the priority guarantee rate (500 kbps) of the designated UE, according to Z kbps 1 ＝P 3 ，
Figure BDA0002225841010000102
It can be determined that the resource reservations allocated by the base station for three users, i.e., user a, user B, and user C, are as shown in table 2, and thus can be ignoredUnder the premise of responding to the user admission control, the differentiated rate guarantee service of the network to the users in different levels is realized, and the proportional fairness is also taken into consideration.

Three users, namely the user A, the user B and the user C, are all carrying out Non-GBR type bearer services, wherein the services carried out by the user A, the user B and the user C all need 600 kbps. If the current resource of the cell is only 400kbps and PBR =8kbps and PGBR =500kbps, the base station determines that the current resource (400 kbps) is less than the sum of the traffic rates (600kbps +600kbps = 1800kbps), if the current resource (400 kbps) is less than the traffic rate (600 kbps) of the designated UE (A user) corresponding to the highest default bearer priority and the traffic rate (600 kbps) of the designated UE is greater than the priority guarantee rate (500 kbps) of the designated UE, then according to Z 1 ＝W-(N-1)×P 2 ，Z 2 ＝P 2 The base station can be determined to be allocated to three users of A user, B user and C userThe resource reservation is shown in table 3, so that differentiated rate guarantee service of the network to users of different levels can be realized on the premise of not influencing the access control of the users, and proportional fairness is also considered.

Three users, namely the user A, the user B and the user C, are all carrying out Non-GBR type bearer services, wherein the services carried out by the user A, the user B and the user C all need 500 kbps. If the current resource of the cell is only 400kbps and PBR =8kbps and PGBR =600kbps, then the base station determines that the current resource (400 kbps) is less than the sum of the traffic rates (500kbps +500kbps = 1500kbps), and if the current resource (400 kbps) is less than the traffic rate (500 kbps) of the designated UE (A user) corresponding to the highest default bearer priority and the traffic rate (500 kbps) of the designated UE is greater than the priority guarantee rate (600 kbps) of the designated UE, then according to Z 1 ＝W-(N-1)×P 2 ，Z 2 ＝P 2 Can determine the base station asThe resource reservation distributed by the three users, namely the user A, the user B and the user C, is shown in the table 4, so that the differentiated rate guarantee service of the network to the users with different levels can be realized on the premise of not influencing the access control of the users, and the proportional fairness is also considered.

For example, under a certain cell coverage of 4G, there are four users, i.e., a, B, C, and D, where a and B are both important users (the user level of the user a is higher than that of the user B), and C and D are normal users. A. The four users B, C and D are all carrying out Non-GBR type bearing service, wherein the services A, B, C and D all need 600kbps rate. If the current resource of the cell is only 800kbps, the PBR =8kbps, the PGBR of the a user =500kbps, and the PGBR of the b user =400kbps, and the base station determines that the current resource of the cell (800 kbps) is less than the sum of the service rates (600kbps +600kbps = 2400s), if the current resource of the cell (800 kbps) is greater than or equal to the service rate (600 kbps) of the designated UE (a user) corresponding to the highest default bearer priority, and the service rate (600 kbps) of the designated UE is greater than the priority guarantee rate (500 kbps) of the designated UE, the base station determines that the current resource of the cell (800 kbps) is greater than or equal to the highest default bearer priority
