Description

Method and apparatus for controlling data service quality

The present invention relates to the field of communications, and more particularly to a method and apparatus for controlling data quality in the field of communications. Background technique

The Long Term Evolution (LTE) system is a next-generation wireless communication system being developed and developed by the 3rd Generation Partnership Project (3GPP). The LTE system has very High spectrum utilization and transmission speed, and low transmission delay.

In the LTE system, when the user equipment (User Equipment, called "UE") initiates initial network access, the following process may be adopted: the UE initiates an attach request, and may carry an access point (Access Point Name) that requires the request. The cylinder is called "APN"indication; the UE and the network perform the security authentication process of the terminal access network, and activate the security association of the non-access stratum, and the Mobility Management Entity ("MME") is from the home subscriber server. (Home Subscriber Server, the tube is called "HSS") to obtain the subscription information of the terminal, including the aggregated bit rate of the user equipment (Aggregate Maximum Bit Rate, called "AMBR") (UE-AMBR Subscribed); MME to the month A service gateway ("SGW") initiates a session establishment request, and the session establishment request includes a default evolved packet system (Evolved Packet System), which is called "EPS". The address of the packet is called "QoS" and the packet data network (Packet Data Network, called "PDN"). If the UE does not carry the APN indication when initiating the attach request, then MM E will bring the default APN indication; the SGW sends a session establishment request to the above PDN address; if the network has policy and charging control (Policy and Charging Control, called "PCC") deployment, the packet data network gateway (PDN) Gateway, called "PGW", performs signaling interaction with the Policy and Charging Rules Function ("PCRF") to establish an IP Connectivity Access Network (IP Connectivity Access Network). For the "IP-CAN" session, the PGW obtains the QoS policy corresponding to the default EPS bearer from the PCRF to establish a default EPS bearer corresponding to the PDN, and the PGW can also obtain the maximum bit rate of the access point aggregation (Access Point Name Aggregate Maximum Bit). Rate, the tube is called "APN-AMBR"), The APN-AMBR identifies the upper limit of the bandwidth corresponding to the APN-related Non-Guaranteed Bit Rate ("Non-GBR") data stream authorized by the PCRF.

The PGW sends a session establishment response to the SGW, and the SGW sends a session establishment response to the MME, where the session establishment response includes an APN-AMBR; the MME obtains the UE-AMBR Subscribed obtained from the HSS and the sum of the currently activated APN-AMBR of each APN. The smaller of the values is determined as the aggregated maximum bit rate (UE-AMBR-IN USE ) used by the user equipment; the MME sends an initial context setup request to the base station (Evolutional Node B, called "eNB"), which is established in the initial context. In the request, the MME carries the value of the UE-AMBR-IN USE to the base station; the base station triggers the establishment of the radio bearer in the air interface, and performs upper limit control on the uplink and downlink non-GBR data of the air interface based on the UE-AMBR-IN USE; After the context is established, the UE sends an attach complete message to the MME; the MME sends a bearer update message to the SGW. At this point, the SGW can send the downstream buffered data stream down.

It can be seen from the above that when the number of PDN connections enabled by the user equipment remains unchanged, it means that the sum of the APN-AMBRs of the currently activated APNs remains unchanged, and thus, when the network status changes, for example, the network appears. When congestion occurs, the UE-AMBR-IN USE on the base station side remains unchanged, thereby failing to effectively control the service quality of the service data, the resource utilization rate is low, and the user body 3 is poor.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without making creative labor are within the scope of the present invention.

It should be understood that the technical solution of the embodiments of the present invention can be applied to various communication systems, for example: Global System of Mobile communication ("GSM") system, code division multiple access (Code Division Multiple Access) Called "CDMA" system, Wideband Code Division Multiple Access ("WCDMA") system, General Packet Radio Service (General Packet Radio Service, "GPRS"), long-term Evolution (Long Term Evolution, "LTE") system, LTE Frequency Division Duplex ("Fluid Division") system, LTE Time Division Duplex ("TDD") , Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access ("Wireless") communication system. The embodiment of the present invention is described by taking an LTE system as an example, but the embodiment of the present invention is not limited thereto.

It should also be understood that in the embodiment of the present invention, a user equipment (User Equipment, referred to as "UE") may be referred to as a terminal (Terminal), a mobile station (Mobile Station, referred to as "MS"), a mobile terminal ( Mobile Terminal), etc., the user equipment can communicate with one or more core networks via a Radio Access Network ("RAN"), for example, the user equipment can be a mobile phone (or "cellular" , a telephone, a computer with a mobile terminal, etc., for example, the user device can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges voice and/or data with the wireless access network.

In the embodiment of the present invention, the base station may be a base station (Base Transceiver Station, called "BTS") in GSM or CDMA, or may be a base station (NodeB, called "NB") in WCDMA, or may be The evolved base station (Evolutional Node B, referred to as "eNB or e-NodeB") in the LTE is not limited. However, for convenience of description, the following embodiments will be described by taking an eNB as an example.

1 shows a schematic flow diagram of a method 100 of controlling data quality of service, which may be performed by a base station, such as by an eNB, in accordance with an embodiment of the present invention. As shown in FIG. 1, the method 100 includes:

S110. Determine that congestion occurs in a cell where the user equipment is located.

S120. Determine an aggregate maximum bit rate used by the user equipment in a congestion state.

S130. Control an upper limit of uplink and downlink bandwidth of the non-guaranteed bit rate data according to the aggregated maximum bit rate used by the user equipment in the congestion state.

In order to be able to effectively control the quality of service of the service data, the base station can detect the change of the network state. For example, when determining that the cell where the user equipment is located is congested, the base station can determine the maximum bit rate of the aggregation used by the user equipment in the congestion state, so that the base station can The aggregated maximum bit rate used by the user equipment in the congestion state controls the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate data, so that the bandwidth of the non-guaranteed bit rate data changes as the network state changes.

Therefore, the method for controlling data quality of service according to an embodiment of the present invention is provided by where the user equipment is located. When the cell is congested, the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate data is controlled according to the maximum bit rate of the aggregation used by the user equipment in the congestion state, and the service quality of the service data can be effectively controlled, and the bandwidth can be differentiated and managed. Improve the utilization of network resources, ease network congestion, and improve user experience.

In S110, the base station may be based on downlink power, QoS satisfaction rate, and physical resource block (Physical)

The resource block, called "PRB", takes one or more parameters to determine whether the cell where the user equipment is located is congested.

For example, when the QoS satisfaction rate corresponding to a QoS Class Identifier ("QCI") is lower than the congestion threshold and the uplink or downlink PRB utilization rate of the cell is high, the cell uplink or Downstream congestion. For another example, when the QoS satisfaction rate of a certain QCI in the downlink is lower than the congestion threshold, and the downlink power is limited, the downlink congestion of the cell may be determined.

It should be understood that the QoS satisfaction rate may be: For a GBR bearer with a QCI of 1 to 4, the total amount of data scheduled by all services accounts for the proportion of the total amount of data that all QCI services need to transmit; the PRB utilization rate can be expressed as a GBR service. The total number of required PRBs is a percentage of the total number of available PRBs for the service; the downlink power may be the downlink transmit power of the eNB. It should also be understood that the Non-GBR service may be controlled without congestion control, but by the number of bearer specifications of the Non-GBR of the eNB.

It should be understood that the base station may also determine, according to other methods, whether the cell where the user equipment is located is congested, and the embodiment of the present invention is not limited thereto.

In S120, when determining that the cell where the user equipment is located is congested, the base station may determine, according to the method in the embodiment of the present invention, an aggregate maximum bit rate used by the user equipment in the congestion state (UE-AMBR-IN USE_Update, the tube is called “UE”. -AMBR-IN USEJJ"), which will be described in detail below in conjunction with FIGS. 2 to 10.

In S130, the base station can control the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate (Non-GBR) data according to the aggregated maximum bit rate used by the user equipment in the congestion state, thereby effectively controlling the service quality of the service data. Differentiated management of bandwidth, which can improve the utilization of network resources, alleviate network congestion and improve user experience.

Hereinafter, a method of determining an aggregated maximum bit rate used by a user equipment in a congestion state according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 through 10.

As shown in FIG. 2, optionally, the method 120 for determining an aggregate maximum bit rate used by a user equipment in a congestion state includes:

S121. Determine an aggregate maximum bit rate and network state information currently used by the user equipment. S122. Determine, according to the aggregated maximum bit rate currently used by the user equipment and the network state information, an aggregate maximum bit rate used by the user equipment in the congestion state.

That is, when the base station finds that the cell in which the UE is located is congested, the base station can determine the maximum aggregate bit rate used by the user equipment in the congestion state to control the uplink and downlink bandwidth of the Non-GBR data.

In S121, it should be understood that the base station may obtain the aggregated maximum bit rate (UE-AMBR-IN USE ) currently used by the user equipment according to the initial context establishment request or the context update request sent by the MME; the base station may itself according to the relevant protocol of the communication system. Determine network status information or interact with user equipment/network equipment to obtain network status information. It should also be understood that the base station may also use other methods to determine the aggregated maximum bit rate and network status information currently used by the user equipment, and embodiments of the present invention are not limited thereto.

In the embodiment of the present invention, optionally, the network status information includes at least one of the following information: congestion information of the cell where the user equipment is located, level information of the user equipment, and a non-guaranteed bit rate corresponding to the user equipment. The quality of service level QCI information carried, the proportion information of various applications on the base station, the time information, and the location information of the user equipment.

Specifically, the aggregated maximum bit rate currently used by the user equipment reflects the limit value of the bandwidth of the Non-GBR data stream currently used by the UE. The congestion information of the cell where the user equipment is located may include an indication for indicating that the cell where the user equipment is located is congested. The information may also include congestion level information, which includes, for example, light congestion, moderate congestion, heavy congestion, and the like; the level information of the user equipment may be, for example, an address resolution protocol according to the bearer of the UE (Address Resolution Protocol) The "ARP" level is determined; the quality of service level QCI information carried by the non-guaranteed bit rate corresponding to the user equipment may reflect the priority of the Non-GBR service, and may also reflect the requirements for packet loss and delay, etc.; The proportion information of various applications is, for example, 80% of P2P applications and 20% of web browsing; time information is, for example, a certain time or time of day, according to the tide phenomenon, such as mobile communication traffic after 7:00 pm Significantly increased, and at 9:11 am on weekdays, network traffic is at its peak; The location information is, for example, information that the current UE is in a large mall or crowd gathering area. It should be understood that the embodiments of the present invention are merely described by way of example, but the invention is not limited thereto.

In S122, the base station may determine, according to the aggregated maximum bit rate currently used by the user equipment and the network state information, an aggregate maximum bit rate used by the user equipment in the congestion state.

Specifically, for example, it is assumed that the eNB obtains from the MME under the condition that the network is normally served. The value of the aggregate maximum bit rate UE-AMBR-IN USE currently used by the user equipment is X. The value of the aggregate maximum bit rate UE-AMBR-IN USE_Update used by the user equipment in the congestion state needs to be determined to be Y, then Y can be The following equation (1) determines:

Y = (congestion level weight X user level coefficient weight QCI comprehensive weight eNB on various application priority comprehensive weight time weight geographical weight) * X ( 1 ) where, congestion level weight, user level The coefficient weight, the QCI comprehensive weight, the comprehensive weight of each application priority on the eNB, the time weight, and the geographical weight are all values greater than 0 and less than or equal to 1.

In the embodiment of the present invention, the congestion level weight may be a weight that reflects a cell congestion level. The higher the congestion level, the smaller the congestion level weight, that is, the more the Y value needs to be reduced; and vice versa.

In the embodiment of the present invention, the user level coefficient weight may be a weight that reflects the user priority. For example, the weights of Gold, Silver, and Bronze users can be determined to be 0.9, 0.5, and 0.2, respectively. Such a design is mainly intended to ensure that high-priority users (such as gold-based users) have less discounts or reductions in UE-AMBR-IN USE compared to low-priority users (such as Bronze users) in a network-congested state. For example, the value of UE-AMBR-IN USE in the state of congestion of the gold medal user is close to the value in the normal state of the network.

In the embodiment of the present invention, the QCI comprehensive weight may be a weight that reflects the priority of the QCI value corresponding to all the bearers activated by the current user. For example, the QCI values of all three Non-GBR bearers activated by User A are the highest value of 5 (the highest priority), and the QCI values of all three Non-GBR bearers activated by User B are 8, 8, and 9, respectively; Then, the QCI comprehensive weight corresponding to user A is greater than the QCI comprehensive weight of user B. For example, user A's QCI comprehensive weight is 1, and user B's QCI comprehensive weight is 0.5.

In the embodiment of the present invention, the comprehensive weight of each application priority on the eNB may be another weight that reflects different application types currently activated by the user data. Different applications are sensitive to packet loss and latency, so even the same Bronze users have the same QCI integrated weight, but different weights can be set if the application type is different. For example, User A uses a P2P application, and User B is performing a download, such as Microsoft software, which has different weights. Even when User A and User B are accessing multiple applications, according to the proportion of various applications, the comprehensive weights of various application priorities of the user level can be obtained.

In the embodiment of the present invention, the time weight may be a weight of a network state that may be corresponding to the current time period. For example, for 9:00 to 10:00 in the morning, and 7:00 to 9:00 in the evening, the network may be At the peak of traffic, in order to allow more users to access and use limited network resources in a tight state, the time weight of the time period can be set to be relatively small, for example, 0.5; and during off-peak hours, For example, at noon or late at night, the corresponding time weight can be set to the highest value of 1.

In the embodiment of the present invention, the geographic location weight may be to reflect the geographic location of the terminal, such as a relatively sparsely populated location, or at a soccer game site, or a large shopping center. This parameter is designed to adjust the value of UE-AMBR-IN USE of the terminal in consideration of different scenarios under the condition of congestion, so as to better alleviate network congestion and utilize resources reasonably.

Of course, the base station can also determine the maximum bit rate of the aggregation used by the user equipment in the congestion state by referring to other factors or based on other equations. The embodiment of the present invention is only described by way of example, but the present invention is not limited thereto. It should also be understood that, in the embodiment of the present invention, when an item or pieces of information in the network status information is not considered, the corresponding weight in the above equation (1) may take a value of 1. For example, when the location information is not considered, the value of the geographic location weight can be set to 1.

Therefore, the method for controlling the quality of data service according to the embodiment of the present invention can control the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate data according to the maximum bit rate used by the user equipment in the congestion state when congestion occurs in the cell where the user equipment is located. Effectively control the quality of service data and differentiate the bandwidth management, which can improve the utilization of network resources, alleviate network congestion and improve user experience.

FIG. 3 illustrates another schematic flowchart of a method 120 of determining UE-AMBR-IN USE in a congested state, in accordance with an embodiment of the present invention. As shown in FIG. 3, the method 120 can include:

5123. Send, to the mobility management entity MME, congestion information of a cell where the user equipment is located.

S124: Receive an aggregate maximum bit rate used by the user equipment in the congestion state sent by the MME according to the congestion information, where an aggregate maximum bit rate used by the user equipment in the congestion state is obtained by the MME according to the congestion information and from a home subscriber server HSS. The maximum bit rate of the user equipment aggregation in the congestion state is determined; or the maximum bit rate of the aggregation used by the user equipment in the congestion state is aggregated by the MME according to the maximum bit rate of the user equipment in the congestion state acquired from the HSS, and each currently activated access The sum of the maximum bit rates of the point aggregation is determined.

That is, the base station determines, according to the received message from the MME, the aggregated maximum bit rate used by the user equipment in the congestion state, where the message includes the aggregated maximum bit rate used by the user equipment in the congestion state.

In the embodiment of the present invention, the MME may aggregate the maximum bit rate of the user equipment in the congestion state acquired from the HSS, and directly determine the aggregated maximum bit rate used by the user equipment in the congestion state; The MME may also determine the aggregated maximum bit rate used by the user equipment in the congestion state according to the maximum bit rate of the user equipment aggregation in the congestion state obtained from the HSS and the sum of the maximum bit rates of the currently activated access points. It should be understood that the MME may obtain the aggregated maximum bit rate used by the user equipment in the congestion state from the static subscription data acquired by the HSS when the user equipment is initially attached; the MME may also request the congestion status from the HSS in real time when receiving the congestion information. The aggregate maximum bit rate used by the user equipment is not limited to this embodiment of the present invention.

Specifically, as shown in FIG. 4, the method 600 for controlling data quality of service includes: In S610, the MME obtains subscription data from the HSS, where the subscription data includes not only the aggregated maximum bit rate (UE-AMBR Subscribed) subscribed by the user equipment. The user equipment aggregates the maximum bit rate UE-AMBR_U in the congestion state. It should be understood that the UE-AMBRJJ represents the value of the maximum bandwidth that the subscription data can obtain for the terminal in the network congestion state. For a normal terminal, UE-AMBRJJ should be smaller than UE-AMBR Subscribed, so that in the congestion state, it is possible to calculate the aggregate maximum bit rate UE-AMBR-IN USE_U used by the user equipment in a smaller congestion state, thereby allocating more Small bandwidth to limit the upstream and downstream bandwidth of the terminal's Non-GBR data.

In the embodiment of the present invention, the UE-AMBRJJ may be a value, or may be two or more values corresponding to the congestion level of the cell. For example, the UE-AMBRJJ may include the UE-AMBR_U1 (corresponding to the congestion level). It is level 1), UE-AMBRJJ2 (corresponding to congestion level 2) and UE-AMBRJJ3 (corresponding to congestion level 3).

In S620, when the cell where the UE is located is congested, the eNB may send the congestion information of the cell where the user equipment is located to the MME by using the S1-AP message, where the congestion information may include an indication for indicating that the cell where the user equipment is located is congested. Information, and/or congestion level information.

In S630, the MME may directly determine the UE-AMBRJJ corresponding to the congestion information as the user equipment in the congestion state according to the congestion information and the user equipment aggregation maximum bit rate UE-AMBRJJ in the congestion state acquired from the home subscriber server HSS. The aggregate maximum bit rate UE-AMBR-IN USE_U; The MME may also determine the UE-AMBR-IN USE_U according to the sum of the UE-AMBRJJ acquired from the HSS and the APN-AMBR of each currently activated APN.

Specifically, when the MME obtains the UE-AMBRJJ from the HSS as a value, the MME may determine the UE-AMBRJJ as the UE-AMBR-IN USE_U according to the indication information included in the congestion information; the MME may also use the UE-AMBRJJ And the smaller of the sum of the APN-AMBRs of the currently activated APNs is determined as the aggregation used by the user equipment in the congestion state. Maximum bit rate (UE-AMBR-IN USE_U).

When the MME obtains the UE-AMBRJJ from the HSS as the value corresponding to the congestion level, the MME may determine, according to the congestion level information included in the congestion information, the user equipment aggregation corresponding to the congestion level information in the multiple UE-AMBRJJs. The maximum bit rate, for example, when the congestion level is 2, the MME may determine the user equipment aggregation maximum bit rate UE-AMBR_U2 corresponding to the congestion level information as UE-AMBR-IN USE_U; the MME may also activate UE-AMBR_U2 and currently activated. The smaller of the sum of the APN-AMBRs of the respective APNs is determined as the aggregate maximum bit rate (UE-AMBR-IN USE_U) used by the user equipment in the congestion state.

That is, the MME can determine the aggregate maximum bit rate UE-AMBR-IN USEJJ used by the user equipment in the congestion state according to the following equation (2):

UE-AMBR-IN USE_U=min { UE- AMBR-U, ^ (APN - AMBR), } ( 2 ) where ( APN- AMBR ) i is the currently active APN-AMBR of the i-th APN; n is the current The number of activated APNs.

In S640, the MME may send a context update request to the eNB through the S1 interface to send the UE-AMBR-IN USEJJ to the eNB, so that the eNB can control the non-guaranteed bit rate according to the aggregated maximum bit rate used by the user equipment in the congestion state. The upper limit of the upstream and downstream bandwidth of the data.

It should be understood that, in various embodiments of the present invention, the size of the sequence numbers of the above processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be taken to the embodiments of the present invention. The implementation process constitutes any limitation.

FIG. 5 shows another schematic flowchart of a method 120 of determining UE-AMBR-IN USE in a congestion state according to an embodiment of the present invention. As shown in FIG. 5, the method 120 can include:

5125. Send, to the mobility management entity MME, congestion information of a cell where the user equipment is located.

S126, receiving an aggregate maximum bit rate used by the user equipment in the congestion state sent by the MME according to the congestion information, where an aggregate maximum bit rate used by the user equipment in the congestion state is used by the policy and charging rule function entity PCRF according to the user equipment. Aggregate maximum bit rate, and root Determined according to the congestion information and/or the level information of the user equipment, and through the packet data network gateway

The PGW and the Serving Gateway SGW are sent to the MME.

That is, the PCRF re-authorizes the aggregated maximum bit rate used by the user equipment in the congestion state. A detailed description will be given below in conjunction with FIG. 6.

Specifically, for example, as shown in FIG. 6, the method 700 for controlling data quality of service includes: In S710, when the eNB detects that the cell where the UE is located is congested, the eNB may notify the MME that congestion occurs through the S1-AP message, and the eNB The congestion information sent to the MME may include indication information indicating that the cell where the user equipment is located is congested, and/or the congestion level information is in S720. As an enhancement of the present invention, the modify bearer message may be sent to the PGW through the SGW. The modified bearer message carries the aggregate maximum bit rate UE-AMBR-IN USE used by the current user equipment. Optionally, the modification bearer message further carries congestion level information.

In S730, the PGW sends the UE-AMBR-IN USE to the PCRF; optionally, the PGW also sends the congestion level information to the PCRF.

In S740, the PCRF determines the maximum bit rate of the access point aggregation in the congestion state according to the maximum bit rate of the aggregation currently used by the user equipment. Specifically, the PCRF may determine the maximum bit rate of the access point aggregation in the congestion state according to the aggregated maximum bit rate UE-AMBR-IN USE currently used by the user equipment, and according to the congestion information and/or the level information of the user equipment. -AMBR-IN USE_U. It should be understood that the PCRF may also determine UE-AMBR-IN USE_U in combination with other parameters, and embodiments of the present invention are not limited thereto.

For example, if the value of the aggregate maximum bit rate UE-AMBR-IN USE currently used by the user equipment is X, the value of the aggregate maximum bit rate UE-AMBR-IN USE_U used by the user equipment in the congestion state needs to be determined to be Y. Y can be determined by the following equation (3):

Y = (user level coefficient weight * congestion level weight) * Χ ( 3 ) where the congestion level weight and the user level coefficient weight are both values greater than 0 and less than or equal to 1. In the embodiment of the present invention, the meanings and value rules of the congestion level weights and the user level coefficient weights are the same as those of the foregoing embodiment, and are not described herein again.

In S750, the PCRF may modify the reply message through the IP-CAN session, and send the aggregated maximum bit rate UE-AMBR-IN USE_U used by the user equipment in the determined congestion state to the PGW.

In S760, the PGW sends an update bearer message to the SGW, where the update bearer message carries

The value of the UE-AMBR-IN USE_U, the SGW further sends an update bearer message to the MME, to The value of UE-AMBR-IN USE_U is sent to the MME.

In S770, the MME sends a context update request to the eNB, where the request carries the value of the UE-AMBR-IN USE_U, so that the eNB can control the non-guaranteed bit rate data according to the aggregated maximum bit rate used by the user equipment in the congestion state. The upper limit of the upstream and downstream bandwidth.

FIG. 7 shows still another schematic flowchart of a method 120 of determining UE-AMBR-IN USE in a congestion state according to an embodiment of the present invention. As shown in FIG. 7, the method 120 can include:

5127. Send, to the mobility management entity MME, congestion information of a cell where the user equipment is located.

S128: Receive an aggregate maximum bit rate used by the user equipment in the congestion state sent by the MME according to the congestion information, where an aggregate maximum bit rate used by the user equipment in the congestion state is used by the MME according to a congestion state obtained from a PCRF. The aggregation maximum bit rate determines that the maximum bit rate of the access point aggregation in the congestion state is aggregated by the PCRF according to the contracted access point, and is determined according to the congestion information and/or the level information of the user equipment.

That is, in the case that the cell where the user equipment is located is congested, the PCRF re-authorizes the maximum bit rate of the access point in the congestion state, and the MME can aggregate the maximum bit rate according to the access point in the congestion state. The aggregation maximum bit rate UE-AMBR-Subscribed, which is subscribed by the user equipment, determines the aggregate maximum bit rate used by the user equipment in the congestion state, which will be described below with reference to FIG. 8.

For example, as shown in Figure 8, a method 800 of controlling data quality of service includes:

In S810, when the eNB detects the congestion of the cell where the UE is located, the eNB may notify the MME that the congestion occurs by using the S1-AP message, and the congestion information that the eNB sends to the MME may include indicating that the cell where the user equipment is located is congested. The indication information, and/or the congestion level information, in S820, may send a modify bearer message to the PGW through the SGW, where the modified bearer message carries the subscribed access point aggregation maximum bit rate APN-AMBR. Optionally, the modified bearer message further carries congestion level information.

In S830, the PGW sends the APN-AMBR to each PCRF; optionally, the PGW will hold The plug level information is also sent to a PCRF.

In S840, each PCRF aggregates the maximum bit rate APN-AMBR according to the subscribed access point, and determines the maximum bit rate of the access point aggregation in the congestion state according to the congestion information and/or the level information of the user equipment.

For example, if the value of the maximum bit rate of the subscribed access point aggregation APN-AMBR is M, and the value of the maximum bit rate of the access point aggregation APN-AMBRJJ in the congestion state needs to be determined to be N, then N can be represented by the following equation ( 4) Determine:

N = (user level coefficient weight * congestion level weight) *M ( 4 ) where the congestion level weight and the user level coefficient weight are both values greater than 0 and less than or equal to 1. In the embodiment of the present invention, the meanings and value rules of the congestion level weights and the user level coefficient weights are the same as those of the foregoing embodiment, and are not described herein again.

In S850, each PCRF may modify the reply message through the IP-CAN session, and send the access point aggregation maximum bit rate APN-AMBRJJ to the PGW in the determined congestion state.

In S860, the PGW sends an update bearer message to the MME through the SGW to send the value of the APN-AMBRJJ to the MME.

In S870, the MME may aggregate the maximum bit rate of the access point according to the aggregated maximum bit rate UE-AMBR-Subscribed (called "UE-AMBR-S") subscribed by the user equipment according to the congestion state of each currently activated APN. The rate APN-AMBRJJ determines the aggregate maximum bit rate (UE-AMBR-IN USEJJ) used by the user equipment in the congestion state. For example, the MME may determine the aggregate maximum bit rate UE-AMBR-IN USE_U used by the user equipment in the congestion state according to the following equation (5):

UE-AMBR-IN USE_U=min{ UE-AMBR-S, ∑(APN - AMBR_U), } ( 5 ) where ( APN-AMBRJJ ) i is the APN-AMBRJJ of the currently activated i-th APN; n is the current The number of activated APNs.

In S880, the MME may send a context update request to the eNB through the S1 interface, so as to

The UE-AMBR-IN USEJJ is sent to the eNB, so that the eNB can control the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate data according to the aggregated maximum bit rate used by the user equipment in the congestion state.

It should be understood that, in various embodiments of the present invention, the size of the sequence numbers of the above processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be taken to the embodiments of the present invention. The implementation process constitutes any limitation. Therefore, the method for controlling the quality of data service according to the embodiment of the present invention can control the upper limit of the uplink and downlink bandwidth of the non-guaranteed bit rate data according to the maximum bit rate used by the user equipment in the congestion state when congestion occurs in the cell where the user equipment is located. Effectively control the quality of service data and differentiate the bandwidth management, which can improve the utilization of network resources, alleviate network congestion and improve user experience.

FIG. 9 illustrates yet another schematic flow diagram of a method 100 of controlling data quality of service in accordance with an embodiment of the present invention. As shown in FIG. 9, S120 in the method 100 may include:

S129. Receive an aggregate maximum bit rate used by the user equipment in the congestion state sent by the MME, where an aggregate maximum bit rate used by the user equipment in the congestion state is determined by the MME according to a maximum bit rate of user equipment aggregation in a congestion state acquired from the HSS. The maximum bit rate of the user equipment aggregation in the congestion state is determined by the HSS after receiving the congestion information sent by the management server, according to the aggregated maximum bit rate and network status information subscribed by the user equipment.
