Description
Technical field
The present invention relates to the wireless access wide band technology field, relate in particular to the method and system of a kind of ensuring mobile network downward message QoS (Quality of Service, service quality).
Background technology
In the mobile network, network is divided into Access Network and core net two parts, the terminal use is connected to core net by Access Network, the IEEE802.16 protocol suite has defined WiMAX (Worldwide Interoperabilityfor Microwave Access, inserting of microwave whole world interoperability) the wireless access technology air-interface standard of agreement, representative standard comprises that IEEE802.16d fixed wireless access standard and IEEE802.16e mobile wireless insert standard.The IEEE802.16 protocol suite has only defined the wireless data link layer technology relevant with physical layer, though defined the mobility characteristic of WiMAX at IEEE 802.16e, does not all carry out standardization for large-scale network-estabilishing and the management of WiMAX.These all make WiMAX also can't possess the ability that carrier class is used.At present, with research WiMAX technology and to work out related specifications be that target has been set up WiMAX NWG (Network Working Group specially, network working group), simultaneously, the main task that the global interoperability of being made up of equipment manufacturers, device supplier, operator etc. of inserting of microwave authenticates industry alliance is by radio reception device being carried out the authentication of compatibility and interoperability, eliminate the obstacle that the IEEE802.16 standard exists in application, enlarge its range of application.
Aspect the wireless access technology air-interface standard, compare with existing other wireless access standard, the WiMAX protocol definition more the QoS of horn of plenty guarantee mechanism, the maximum transmitted time delay of message and maximum time jitter are two important parameters that QoS guarantees.Because the WiMAX agreement not only can be distinguished different terminal uses to the assurance of QoS, and can distinguishing terminal with indoor different business, the WiMAX agreement is that different business adopts different types of QoS to guarantee mode, and this is notable feature and the key technology of WiMAX agreement.
WiMAX NWG specified in more detail the network system architecture of WiMAX agreement, be illustrated in figure 1 as ASN (Access Service Network, access service network, hereinafter to be referred as Access Network) reference model, this ASN reference model comprises two network element: BS (Base Station, the base station) and ASN GW (ASN Gateway, access service network gateway, hereinafter to be referred as the Access Network gateway), BS mainly is responsible for wireless access and the RRM of WiMAX, and ASN GW is responsible for terminal use's access-in management, mobile management and data channel management.Be data channel with the channel definition of transmitting message among the mobile network between network element, the bearing mode of the data channel that WiMAX NWG recommends has IPinIP (Internet Protocol in Internet Protocol) encapsulation technology, simple layer two network encapsulation technology and MPLS (Multi-Protocol Label Switching, the multi protocol label exchange) encapsulation technology, wherein, most typical in the IPinIP encapsulation technology is GRE (GenericRouting Encapsulation, generic route encapsulation), be typically the Ethernet encapsulation technology in the simple layer two network encapsulation technology.In addition, the mobile network than higher, BS and ASN GW have all disposed GPS and obtain clock reference and realize the location at present, do not need to extract clock from business interface to the synchronous requirement of clock.
Function for BS and ASN GW is divided, the WiMAX agreement has proposed two class schemes: first kind scheme is that the function of BS and ASN GW is carried out physically division, and the distribution difference of function point, therefore there are two independent network element in the Access Network, the second class scheme is that BS and ASN GW have been put into together physically, regard BS and ASN GW as a network element this moment, but, in practice, according to the first kind scheme BS and ASN GW are carried out the range of application that function divides and to be far longer than the second class scheme.
With regard to first kind scheme, owing to there are two independent network element, during as if functions such as the Idle state that will realize the agreement regulation and switchings, ASN GW must carry out buffer memory to message, simultaneously, ASN GW realize in inside some handle as flow control etc. and also may carry out buffer memory to message, buffer memory just is equivalent to delayed delivery.In addition, because what eat dishes without rice or wine and the terminal use of base station set up is the limited wireless connections of bandwidth, the base station also needs buffer memory to the message that issues, be that message waits for that the required time of air-interface scheduling is the main delayed delivery time of base station side, the time delay that inside of base station produces also comprises dormant state time-delay, buffer memory time-delay and the processing delay that carried out the base station when terminal use was scanned, wherein, eating dishes without rice or wine is the abbreviation of air interface.
In the prior art, when core net issues the real time business message by Access Network to the terminal use, whole mobile network is when carrying out the QoS assurance, can only be according to each equipment vendors way separately, parameters such as the time delay of the message wait air-interface scheduling that statistics produces a network element BS inside and processing delay, and pass through priority algorithm according to this delay parameter message is carried out dispatching down distributing, this delay parameter does not conform to the overall delay of statistics in Access Network of IEEE802.16 protocol requirement, overall delay in Access Network refers to that message is from initially entering ASNGW to the total time-delay of BS during to its dispatching down distributing, prior art has neglected the time-delay that message produces through ASN GW the time, this must guarantee the QoS of message to threaten, and causes finally influencing the user and experiences.
