Embodiment 1

[0060] In this embodiment, the improved SRTCM algorithm is applied to the traffic shaping of the non-GBR bearer.

[0061] APN-AMBR is the subscription information of each APN stored in the Home Subscriber Server (HSS). On the S58 interface (the interface between the PGW and the SGW), when performing traffic shaping based on the bearer level, the non-GBR bearer is shaped according to the APN-AMBR.

[0062] TS23.401 stipulates that for all non-GBR bearers of the same PDN connection of the same UE, the shared APN-AMBR mechanism is used to realize resource utilization. That is, when there are multiple non-GBR bearers under the PDN connection, if some of the non-GBR bearers do not transmit services, other active non-GBR bearers can share the entire APN-AMBR bandwidth resources. Since the default bearer is generally a non-GBR bearer, the shaping template corresponding to the non-GBR bearer under the same PDN connection is generally created when the default bearer is established. A...

Embodiment 2

[0081] This embodiment applies the SRTCM algorithm to traffic shaping carried by the GBR.

[0082] For each GBR bearer, there are two parameters corresponding to GBR and MBR. GBR indicates the bit rate that the bearer can provide. MBR indicates the maximum bit rate that the bearer can provide. On the S58 interface, when performing traffic shaping based on the bearer level, the traffic shaping is performed based on the MBR for the GBR bearer.

[0083] When creating a GBR bearer, configure a corresponding shaping template according to the bearer QoS parameters. According to the data model of the token bucket algorithm, make the following settings:

[0084] CIR (Committed Information Rate): MBR carried by GBR, the unit is bit.

[0085] CBS (Committed Burst Size): The number of tokens when the token bucket is full of tokens.

[0086] Tc: The number of tokens in the token bucket, the initial value is CBS.

[0087] B: The number of tokens required by the data message, calculate...

Embodiment 3

[0102] This embodiment is aimed at traffic shaping when the service processing capability of the PGW is limited, and the SRTCM algorithm is applied. Token buckets are shared for each service, and the bucket size is set to the remaining bandwidth, and bandwidth preemption is performed according to service priorities.

[0103] Status of the protocol: TS23.203 stipulates that the QCI value corresponding to the guaranteed bit rate bearer, that is, the GBR bearer, is 1 to 4. The service processing unit of the PGW must guarantee the GBR value of the bearer when the bearer tunnel is established. Relatively, Non-guaranteed bit rate bearers, that is, non-GBR bearers, correspond to a QCI value of 5 to 9. For all non-GBR bearers connected to the same PDN, in order to improve the statistical multiplexing effect of bearer resources, the shared APN-AMBR mechanism is adopted Resource utilization is realized. At this time, the service processing unit does not need to guarantee the APN-AMBR ba...

Abstract

The embodiment of the invention discloses a data packet processing method and device, relates to the technical field of wireless communication, and is used to solve the problem of how to perform traffic shaping on a data stream. In the present invention, when the data packet arrives, it is determined according to the single-rate single-token bucket SRTCM algorithm to forward the data packet or discard the data packet; according to the determination result, the data packet is forwarded or discarded. By adopting the invention, the problem of how to carry out traffic shaping on the data flow can be solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a data packet processing method and device. Background technique [0002] In the TS23.203 protocol, the quality of service (Quality of Service, QoS) parameters of the bearer level are described, including the QoS class identifier (QoS Class Identifier, QCI), allocation and retention priority (Allocation and Retention Priority, ARP) , Guaranteed Bit Rate (GBR), Maximum Bit Rate (MBR), Aggregate Maximum Bit Rate (AMBR), etc. [0003] Evolved Packet System (Evolved Packet System, EPS) bearers include GBR bearers and non-GBR (Non-GBR) bearers. Each EPS bearer is associated with a QCI parameter. QCI is a quantitative class used to represent access point parameters that control packet transmission processing at the bearer level. [0004] In addition, each GBR bearer is also associated with GBR and MBR parameters. GBR represents the expected bit rate that can be provide...
