Based on the same idea, another embodiment of the present invention also provides a method for controlling quality of service. As shown in fig. 2, the method includes:
201. a base station receives a downlink data message;
wherein the downlink data message comprises an FPI;

The method for controlling the quality of service provided by the embodiment of the present invention will be described in detail below by using a specific example. As shown in fig. 3:
301. the UE access network establishes a packet data network connection between the UE and a gateway and a default bearer or Packet Data Protocol (PDP) context;
302. the PCEF carries out service detection;
when a downlink data packet passes through, the PCEF performs service detection based on IP quintuple or deep packet analysis (DPI) technologies and the like. When the PCEF detects a new service, the PCEF reports the detection result to the PCRF. Illustratively, a Traffic Detection Function (TDF) mechanism and a Gx/Sd interface may be used to implement that the PCEF reports the Detection result to the PCRF, for example, an Application-Detection-Information cell in the CC-Request message carries the detected traffic Information.
The PCEF obtains the FPI of the downlink data packet, which may be as shown in 303a to 303b, or as shown in 303c to 303 e.
303a, acquiring the FPI corresponding to the downlink data message by the PCRF;
illustratively, the PCRF may obtain the corresponding FPI according to at least one of a service priority of the service to which the downlink data packet belongs, a user cumulative usage level of the service to which the downlink data packet belongs, a user level of the service to which the downlink data packet belongs, and a type of the UE that receives the downlink data packet, and a service type of the service to which the downlink data packet belongs. For example, the PCRF may pre-configure an FPI subscription table. As shown in table 1 below, after the PCRF receives the service detection result reported by the PCEF, the PCRF queries table 1 to obtain a corresponding FPI according to the service type corresponding to the downlink data packet, the level of the cumulative usage of the user, whether the service is signed, and the level of the user. Those skilled in the art should understand that table 1 is only an exemplary illustration, and the specific content can be adjusted according to the practical application, which is not limited by the embodiment of the present invention.
TABLE 1
Type of service User accumulated usage level Whether a service signs a contract or not User ratings FPI
Video Is low in Is that Height of 1
Video Is low in Whether or not Height of 2
Video Height of Whether or not In 3
Web page browsing Is low in Whether or not In 4
Web page browsing Height of Whether or not In 5
For another example, the PCRF may also calculate the FPI according to at least one of the service priority of the service to which the downlink data packet belongs, the user cumulative usage level of the service to which the downlink data packet belongs, the user level of the service to which the downlink data packet belongs, and the type of the UE that receives the downlink data packet, by using a certain specific formula.
The parameters related to the downlink data packet, such as the service priority of the service to which the downlink data packet belongs, the user cumulative usage level of the service to which the downlink data packet belongs, the user level of the service to which the downlink data packet belongs, and the type of the UE receiving the downlink data packet, are merely exemplary examples, and other quality of service parameters may be adopted in practical application, which is not limited in the embodiment of the present invention.
303b, the PCRF sending the FPI corresponding to the downlink data packet to the PCEF;
illustratively, the PCRF may issue a policy and Charging control (PolicyandChargingControlPCC) Rule to the PCEF through the Gx interface, where the policy and Charging control pcc Rule includes an FPI corresponding to the downlink data packet, for example, the FPI corresponding to the downlink data packet is carried in a Charging-Rule-instruction cell in the CC-Answer message.
303c, generating a PCC rule by the PCRF;
wherein the PCC rule includes at least one of a service priority of a service to which the downlink data packet belongs, a user cumulative usage level of the service to which the downlink data packet belongs, a user level of the service to which the downlink data packet belongs, and a type of the UE that receives the downlink data packet.
303d, the PCRF issues a PCC rule to the PCEF;
illustratively, the PCRF issues the PCC Rule to the PCEF through the Gx interface, for example, service priority information may be carried by a Charging-Rule-lnstall cell in a CC-Answer message.
303e, the PCEF obtains the FPI corresponding to the downlink data message;
for example, the PCEF may obtain the corresponding FPI according to at least one of the service priority of the service to which the downlink data packet belongs, the user cumulative usage level of the service to which the downlink data packet belongs, the user level of the service to which the downlink data packet belongs, and the type of the UE receiving the downlink data packet, and the service type of the service to which the downlink data packet belongs. For example, the PCEF may also obtain the corresponding FPI by configuring the FPI subscription table, which may specifically refer to the content in 303a, which is not described herein again.
304. The PCEF carries the obtained FPI in the downlink data message;
illustratively, the PCEF may carry the FPI in the downlink data packet in a user plane data packet marking manner. For example, the FPI may be carried in a tunnel encapsulation header of a downlink data packet or carried in an IP packet header, and the following examples do not limit the embodiments of the present invention.
1) The FPI is carried through the tunnel encapsulation head.
For GPRS Tunneling Protocol (GTP) interfaces, such as Gn/Gp, S5/S8, and Iu interfaces, a GTP-U header extension mode may be used to carry the FPI, as shown in tables 2 and 3, where the extension header type is 00, so as not to affect other network elements.
TABLE 2
TABLE 3
For interfaces of proxy mobile IP protocol version six (PMIPv6), such as S2a, S2b, FPI can be carried in an added field in Generic Routing Encapsulation (GRE), or can be carried using Reserved0 or Reserved1 cells in existing GRE encapsulation, as shown in table 4.
TABLE 4
2) The IP message header carries the FPI, so that tunnel encapsulation does not need to be expanded;
for example, for the IPv4 message, a Differentiated Services Coding Point (DSCP) field may be used to identify the FPI, as shown in table 5. In this embodiment, only DSCP in the IP header of the application layer in the tunnel carries the FPI, so that the scheduling of the intermediate node is not affected, and the DSCP in the IP header of the outer layer of the tunnel is not affected by the intermediate node.
TABLE 5
For another example, for the IPv6 message, a TrafficClass field may be used to carry the FPI, as shown in table 6.
TABLE 6
It should be noted that the above-mentioned ways of carrying FPIs are only examples commonly used, but the specific application is not limited thereto, and the details are not repeated herein.
305. And the PCEF sends the downlink data message to the base station.
Optionally, the PCEF may send the downlink data packet according to the FPI of the downlink data packet. For example, the PCEF may prioritize and schedule the downlink data packets based on the FPI, and preferentially send the downlink data packets with a high priority of the traffic flow.
Optionally, when the downlink data packet passes through the intermediate node, the intermediate node may also forward the downlink data packet according to the FPI of the downlink data packet. For example, the intermediate node may prioritize and schedule the downlink data packets based on the FPI, and preferentially send the downlink data packets with high priority of the traffic flow.
306. And the base station sends the downlink data message to the UE according to the FPI of the downlink data message.
In this embodiment, sending the downlink data packet based on the FPI may be implemented in various ways, and this embodiment is only described in the following way, but is not limited thereto. For example, the downlink data packet may be sent to the UE according to the order of the priority levels of the service flows indicated by the FPI, or the downlink data packet may be sent to the UE according to the weight information corresponding to the FPI and the weight information corresponding to the bearer to which the downlink data packet belongs.
Next, the downlink data packet is transmitted according to the weight information corresponding to the FPI and the weight information of the bearer corresponding to the downlink data packet.
For example, as shown in table 7, there are three users in a cell, each user has a bearer, and the weights are 100, 50, and 50; each carrying three queues, with weights of 60, 30 and 10, respectively, each queue may correspond to 2 different FPIs. When a downlink data packet passes through, the downlink data packet may be inserted into a corresponding queue according to the bearer to which the downlink data packet belongs and the FPI of the downlink data packet. When a base station sends a downlink data message, the base station firstly distributes scheduling opportunities (2: 1: 1) of each bearer according to the weight of the bearer, once the bearer is scheduled, the base station then distributes the scheduling opportunities (6: 3: 1) of the queues according to the weight of the bearer, and selects the downlink data message in the corresponding queues to send, based on the scheduling opportunities, the downlink data message of the service flow with high priority can be sent preferentially, the downlink data message of the service flow with low priority is sent in a delayed manner, the control of end-to-end service quality based on the granularity of the service flow is realized, the service flow can be processed in an end-to-end differentiated manner, differentiated service experience is provided for users with different grades and different types of services, and the utilization efficiency of wireless resources is effectively improved.
TABLE 7
It should be noted that the working mechanism for the PCEF and the intermediate node to send the downlink data packet according to the FPI may refer to the working mechanism for the base station to send the downlink data packet according to the FPI, which is not described herein again.
According to the method for controlling the service quality, the priority level of the service flow is indicated by utilizing the one-dimensional scalar FPI, the downlink data message comprising the FPI is sent to the base station through the strategy and charging execution functional entity, and the base station sends the downlink data message of the service flow according to the FPI, so that the control of the end-to-end service quality based on the granularity of the service flow is realized, the end-to-end differentiated processing can be performed on the service flow, the differentiated service experience is provided for users of different levels and different types of services, and the utilization efficiency of wireless resources is effectively improved.
Based on the same idea, another embodiment of the present invention provides a policy and charging enforcement function entity. As shown in fig. 4, the policy and charging enforcement function entity includes an obtaining unit 401, a marking unit 402, and a sending unit 403. Wherein,
