The intelligent mobile terminal may be: a smart phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a smart watch, a smart bracelet, etc. device, or the intelligent mobile terminal may also be other types of intelligent mobile terminals, which are not specifically limited in this embodiment of the present invention.

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 UEs, an evolved UMTS terrestrial radio access network (full English name: UMTS Terrestrial Radio Access Network, abbreviation: E- UTRAN), a core network (full name in English: Evolved Packet Core, abbreviation: EPC) and an interconnection protocol (full name in English: Internet Protocol, abbreviation: IP) service between the network of the operator. The Evolved Packet System (full name in English: Evolved Packet System, EPS for short) can be connected with other access networks (not shown in the figure).

E-UTRAN includes Evolved Node B (English full name: Evolved Node B, abbreviated: eNB) eNodeB and other eNodeBs, and may also include a Multicast Coordination Entity (English full name: Multicast Coordination Entity, abbreviated: MCE). An eNodeB can connect with other eNodeBs through a backhaul (eg, an X2 interface). The MCE may allocate time-frequency wireless resources for a multimedia broadcast and multicast service (English full name: evolved Multimedia Broadcast Multicast Server, abbreviated as: eMBMS), and determine a wireless configuration (eg, MCS) for eMBMS.

MBMS-GW can be used as an eNodeB that publishes MBMS services to a multicast/multicast single frequency network (English full name: Multicast Broadcast Single Frequency Network, abbreviated: MBSFN) area belonging to a broadcast specific service, and can also be used for call back management (starting /stop) and collect eMBMS related billing information.

The UE can perform signal communication through a Long Term Evolution (English full name: Long Term Evolution, abbreviation: LTE) network and a millimeter wave (English full name: millimeter wave, abbreviation: mmW) system. Thus, the UE can communicate with the eNodeB and/or other eNodeBs over the LTE link. In addition, it is also possible to communicate with other connection points (full name in English: connection point, CP for short) or base stations through the mmW link.

In the prior art, a UE needs to establish a default bearer when accessing an access point (full English name: Access Point Name, abbreviation: APN) of a certain network. According to the protocol, the default bearer is a non-guaranteed bit rate (English full name: Non-Guaranteed Bit Rate, abbreviated as: Non-GBR) bearer, and the resources required for the bearer are allocated in a best-effort manner. Meet the speed requirements of the business.

Corresponding to Non-GBR, there is also a Guaranteed Bit Rate (English full name: Guaranteed Bit Rate, abbreviation: GBR) bearer, which is usually established when a user initiates some specific services. This GBR bearer is configured with a minimum guaranteed rate (GBR) parameter. During the establishment of a GBR bearer, if the network resources do not meet the GBR requirements, the GBR bearer can be rejected; if the network resources meet the GBR requirements, the network will be the GBR bearer during the lifetime of the bearer. Allocate dedicated resources to ensure the bearer's GBR needs. The priority of GBR bearer is usually higher than that of Non-GBR bearer, and is mostly used for services that require stable bandwidth resources.

As network load increases and competition intensifies, operators need to segment customers and provide hierarchical guarantees for different user groups for the purpose of refined network operations. Existing 4G networks establish Non-GBR default bearers for users of different levels, but hardly guarantee the service quality of Non-GBR bearers (only a very low bit rate is guaranteed, generally PBR=8kbps～32kbps). In order to solve the above problem, in the resource allocation method provided by the embodiment of the present invention, the base station can determine the priority bit rate and priority of each UE by obtaining the default bearer priority of each UE that performs the Non-GBR bearer service within the coverage area. Guaranteed rate; further determine the resource reservation of each UE in each user level according to at least two of the current resource remaining, 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 guaranteed.

Exemplarily, the user level includes a first level and a second level for illustration, where the first level is an important user, the second level is an ordinary user, and the priority of the first level is higher than that of the second level. The specific implementation process is as follows:

Example 1

An embodiment of the present invention provides a resource allocation method, as shown in FIG. 2 and FIG. 3 , including:

S101. The base station acquires the user level, the default bearer priority and the service rate of the Non-GBR bearer service of each UE within the coverage area that performs the Non-GBR bearer service.

It should be noted that, in practical applications, the user level and default bearer (Non-GBR) priority of each UE can be configured in the core network through the user classification policy; thus, when the UE initiates a Non-GBR bearer service request , the core network feeds back the UE's user level and default bearer priority to the base station according to the UE's Non-GBR bearer service request, so that the base station can know the user level, Default bearer priority.

It should be noted that the user level corresponds to the default bearer priority one-to-one, and the higher the user level is, the higher the default bearer priority is.

Exemplarily, it is assumed that the user level includes a first level and a second level, and when the priority of the first level is higher than the priority of the second level, the default bearer priority corresponding to the first level is also higher than that of the second level. The default bearer priority corresponding to the class.

S102, the base station determines the priority bit rate (full English name: Prioritized Bit Rate, PBR for short) and priority guaranteed rate (full English name: Prioritized Guaranteed Bit Rate, abbreviation: PGBR) of each UE according to the default bearer priority.

It should be noted that, in practical applications, for Non-GBR bearers with different priorities, PBR can be defined separately, which is similar to the minimum guaranteed rate in GBR bearers, which is used to calculate the Non-GBR bearer in the admission control process. The minimum guaranteed rate required, and resources are allocated preferentially in the scheduling process for PBR rate guarantee.

For Non-GBR bearers, the PBR bandwidth is usually only used to transmit important exchange signaling information for maintaining bearer connections to meet the needs of maintaining basic connections and avoid high-priority logical channels always occupying a large amount of resources, resulting in low-priority logical channels. Logical channels have problems such as connection loss due to inability to obtain resources.

Among them, PGBR is used for resource scheduling, which can realize differentiated services for different user levels in the network without affecting user admission control.

Specifically, on the base station side, the required PBR (usually 8kbps, 16kbps or 32kbps) and PGBR (which can be configured to a relatively high rate value such as 500kbps, 1mbps, etc. according to the user level) are respectively set corresponding to different default bearer priorities.

Exemplarily, the PBR of each user level in the base station is set to 8kbps, the PGBR of important users can be set to 500kbps uniformly, and the PGBR of common users can be uniformly set to 0.

or,

The PBR of each user level in the base station is set to 8kbps, and the PGBR of important users is configured with the rate value according to the user level determined by the operator's actual level division (for example: A user and B user are both important users, but according to the operator The user level of user A determined by the actual level division is the Nth level, and the user level of the B user determined according to the operator's actual level division is the N-1th level, because the priority of the Nth level is higher than the Nth level. 1-level priority; therefore, the PGBR of user A can be set to 1mbps, the PGBR of user B can be set to 500kbps), and the PGBR of ordinary users can be uniformly set to 0.

Specifically, when user A is upgraded from a common user to an important user, the PGBR of user A is no longer 0 at this time, but the PGBR of user A is determined according to the level division of user A.

Specifically, when the users are all ordinary users, since the PGBR of the ordinary users is 0, there is no proportional relationship between the user level and the PGBR.

S103. The base station determines resource reservation of each UE in each user level according to at least two of the current resource remaining, the priority bit rate, the priority guaranteed rate and the service rate; wherein, the resource reservations corresponding to different user levels are different.

Optionally, the user level includes a first level and a second level; wherein, the first level includes one user;

The base station determines the resource reservation of each UE in each user level according to at least two of the current resource remaining, the priority bit rate, the priority guarantee rate and the service rate, as shown in Figure 3, Figure 4, Figure 5 and Figure 6, including :

S1030. When the base station determines that the current resource remaining is less than the sum of the service rates, if the current resource remaining is greater than or equal to the service rate of the specified UE corresponding to the highest default bearer priority, and the service rate of the specified UE is greater than the priority guaranteed rate of the specified UE, then According to the current resource remaining, the priority bit rate and the priority guarantee rate, determine that the resource reservation of the UE in the first level is Z ₁ , and the resource reservation of each UE in the second level is Z ₂ ;

When the base station determines that the current resource remaining is less than the sum of the service rates, if the current resource remaining is less than the service rate of the specified UE corresponding to the highest default bearer priority, and the service rate of the specified UE is greater than the priority guaranteed rate of the specified UE, then according to the current Resource remaining and priority bit rate, determine that the resource reservation of the UE in the first level is Z ₁ , and the resource reservation of each UE in the second level is Z ₂ ;

in,

Z ₁ =W-(N-1)×P ₂ ;

Z ₂ =P ₂ ;

Among them, P ₁ represents the priority guaranteed rate of the specified UE, P ₂ represents the priority bit rate, P ₃ represents the service rate, W represents the current resource remaining, N represents the total number of UEs carrying the Non-GBR bearer service within the coverage area, and N is greater than or equal to An integer of 1.

Specifically, in practical applications, the method further includes:

S1033. When the base station determines that the current resource remaining is less than the sum of the service rates, if the current resource remaining is less than the service rate of the specified UE corresponding to the highest default bearer priority, and the service rate of the specified UE is less than or equal to the priority guaranteed rate of the specified UE, then According to the current resource remaining and the priority bit rate, determine that the resource reservation of the UE in the first level is Z ₁ , and the resource reservation of each UE in the second level is Z ₂ ;

User A, User B, and User C are all performing Non-GBR bearer services, and the services performed by User A, User B, and User C all require a rate of 600 kbps. If there is only 600kbps of current resources remaining in the cell at this time, and PBR=8kbps, PGBR=500kbps, at this time, the base station determines that the current resource remaining (600kbps) is less than the sum of the service rate (600kbps+600kbps+600kbps=1800kbps), if the current The remaining resource (600kbps) is greater than or equal to the service rate (600kbps) of the specified UE (user A) corresponding to the highest default bearer priority, and the service rate (600kbps) of the specified UE is greater than the priority guarantee rate (500kbps) of the specified UE, then according to
