Problems solved by technology

All terminals currently connected to the same HeNB / HNB, all PDN connections, and all data services (such as voice, video and other data services) are transmitted through the same IPSec tunnel, so different services It is impossible to guarantee the required QoS for its characteristics
Especially in the case of insufficient fixed network resources, if there is no QoS distinction for different types of services, the services with high QoS requirements cannot be carried out or even fail.
For example, a class of BE (Best Effort, Best Effort) services such as data downloads do not have very high requirements for QoS, while services such as voice services have very high requirements for QoS, but because there is no QoS differentiation mechanism, when resources are insufficient , the above two types of services have obtained the same bandwidth (statistically speaking), such bandwidth is sufficient for BE services such as data download, but such bandwidth may not meet the requirements of voice and other services, resulting in a class of voice The transmission quality of the service is extremely poor or even the service fails

Embodiment 1

[0130] Embodiment 1: SeGW parses S1 / Iuh interface message, based on T1T2 architecture ( Figure 8 )

[0131] Step S801: The UE initiates an attach / PDN connection establishment operation, and the related processing of the wireless side and the core network is the prior art.

[0132] Step S802: After the terminal accesses EPS / UMTS through HeNB / HNB, whether it is attachment, PDN connection establishment, terminal-initiated or network-initiated dedicated bearer establishment, the network side will eventually send a corresponding message to HeNB / UMTS HNB, this message is the GTP (GPRS tunnel Protocol, GPRS tunnel protocol) control signaling of the S1 / Iuh interface, the message shown in the figure: initial context establishment request / attachment acceptance / bearer establishment request / PDN connection acceptance. The message carries information such as the QoS rule corresponding to the bearer to be created / modified / released, the uplink and downlink TEID, and the quintuple, that is, ...

Embodiment 2

[0152] Embodiment 2: SeGW parses S1 / Iuh message, based on T1T3 architecture ( Figure 9 )

[0153] Step S901: The UE initiates an attach / PDN connection establishment operation, and the related processing of the wireless side and the core network is the prior art.

[0154] Step S902: After the terminal accesses the EPC / UMTS through the HeNB / HNB, whether it is attachment, PDN connection establishment, terminal-initiated or network-initiated dedicated bearer establishment, the network side will eventually send a corresponding message to the HeNB / UMTS HNB, this message is the GTP control signaling of the S1 / Iuh interface. That is, the message shown in the figure: initial context establishment request / attachment acceptance / bearer establishment request / PDN connection acceptance, for example, the message carries the QoS rule corresponding to the bearer to be created / modified / released, the uplink and downlink TEID, and the quintuple and other information, that is, IP data flow infor...

Embodiment 3

[0174] Embodiment 3: SeGW does not parse the S1 / Iuh message, based on the T1T2 architecture ( Figure 10 )

[0175] Step S1001: The UE initiates an attach / PDN connection establishment operation, and the related processing of the wireless side and the core network is the prior art.

[0176] Step S1002: After the terminal accesses EPS / UMTS through HeNB / HNB, whether it is attachment, PDN connection establishment, terminal-initiated or network-initiated dedicated bearer establishment, the network side will eventually send the corresponding message to HeNB / UMTS HNB, this message is the GTP control signaling of the S1 / Iuh interface. That is, the message shown in the figure: initial context establishment request / attachment acceptance / bearer establishment request / PDN connection acceptance, for example, the message carries the QoS rule corresponding to the bearer to be created / modified / released, the uplink and downlink TEID, and the quintuple and other information, that is, IP data f...

Abstract

The invention discloses a method and a system for realizing control of quality of service, wherein the method comprises the following steps that: SeGW reports corresponding relation information between IPsec tunnel information and IP (Internet Protocol) data stream information in the descending direction to a fixed-network element by a second network element; the SeGW or a first network element reports corresponding relation information between IPsec tunnel information and IP data stream information in the ascending direction by the second network element to the fixed-network element by a second network element; and QoS (Quality of Service) control is controlled by the fixed-network element. In the invention, the condition that the QoS separation is realized for different services when a terminal is accessed from a HeNB / HNB (Home Enhanced Node / Home Node B) can be ensured, the QoS requirement of the services with high QoS requirement is preferably met, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for realizing quality of service (Quality of Service, QoS) control. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3GPP) consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN), mobile management Unit (Mobility Management Entity, MME), Serving Gateway (Serving Gateway, S-GW), Packet Data Network Gateway (Packet Data Network Gateway, P-GW), Home Subscriber Server (Home Subscriber Server, HSS). [0003] figure 1 It is a schematic diagram of the architecture of an evolved home base station (Home evolved NodeB, HeNB) accessing EPS in a non-roaming scenario according to related technologies, as shown in figure 1 As shown, MME is connected with EUTRAN, S-GW and home base station gateway (HeNB GW), and is responsible for mobility management, processing of non-access stratum ...
