Description
Technical field
The present invention relates to wireless communication field, relate in particular to universal mobile telecommunications system grounding wireless access network network (Universal Terrestrial Radio Access Network, UTRAN) the IP service quality in (Quality of Service, QoS) control method.
Background technology
Insert (Wideband Code Division Multiple Access in Wideband Code Division Multiple Access (WCDMA), WCDMA) and the time division multiplexing S-CDMA insert (Time Division Synchronized Code DivisionMultiple Access, TD-SCDMA) include packet-switched domain (PS Domain) in the system, the access service of grouping is provided in their UTRAN.The current IP agreement is popularized in network, the main transmit IP message of packet-switched domain, and whole UTRAN will be evolved to carrying all-IP business in the future.The protocol architecture that downstream IP message is transmitted in the UTRAN of WCDMA and TD-SCDMA comprises as shown in Figure 1:
Packet data polymerized protocol layer (Packet Data Convergence Protocol, PDCP): provide transmission, compression and the support of IP message on radio bearer not have the functions such as service wireless network controller (SRNC) reorientation of losing.In this protocol architecture, has only directly process IP message of PDCP entity.
Wireless chain control layer (Radio Link Control, RLC): carry out PDCP protocol Data Unit (Protocol Data Unit, PDU) burst, reorganization, affirmation re-transmission, ordering, Flow Control etc. the operation and at logic channel Dedicated Traffic Channel (Dedicated Traffic Channel, DTCH) go up transmission, provide message in radio bearer (Radio Bearer, RB) the transmission service on to PDCP.
Media access control layer (Medium Access Control, MAC): the scheduling of message is provided and on transmission channel, transmits, the data transport service of logic channel upwards is provided.Logic channel need be mapped to transmission channel.The transmission channel that the DTCH that stipulates in the 3GPP agreement can shine upon has forward access channel (Forward Access Channel, FACH), dedicated channel (Dedicated Channel, DCH) and high speed descending sharing channel (High Speed Downlink Shared Channel, HS-DSCH).
Radio physical layer (PHY): (User Equipment, UE) the transmission data upwards provide the transmission service of transmission channel (Transport Channel) to user terminal by aerial physical channel.
Traditional IP only designs for the demand that satisfies data service, in this system, all packets all are to transmit according to the principle that transmits (Best Effort) as possible, therefore can be good at supporting web browsing and E-Mail service, but but can not well support the transmission of real-time voice and image.The now IP network develops towards the multiple services direction of single net, in same network, need to carry miscellaneous service, as data, voice, video etc., miscellaneous service is to the requirement difference of time delay, shake, packet loss, different services is provided therefore must for different business, has produced the demand of IP QoS thus.IP QoS exists two kinds of main service models at present: integrated service (Integrated Service, IntServ) model and difference service (Differentiated Service, DiffServ) type.
Intserv model is a kind of QoS service model that early occurs, in this QoS service model, professional by signaling to the specific QoS service of network application, network in the scope of flow parameter reserved resource to satisfy this request.The agreement that intserv model mainly adopts be RSVP (ResourceReserVation Protocol, RSVP).Intserv model needs end-to-end all devices to support RSVP when using, and network element is necessary for each and uses preservation state information, poor expandability, and expense is big, therefore only is applied to edge network at present.
The DiffServ model is different with intserv model, the QoS that it is based on the IP message guarantees, be that the DiffServ model passes through some field of IP header (as IP address/port number/protocol number/COS (Type ofService, ToS) field etc.) distinguish the relative priority level of different messages, on network element, adopt queue scheduling to control the grouping and clustering and the forwarding behavior of different information flows discriminatively, thereby obtain a good compromise between congested guaranteeing service quality and solve.The DiffServ model does not need extra signaling support, does not need to keep the state information of each application yet, is with good expansibility, and therefore can be applicable to catenet.DiffServ technology commonly used at present comprises message classification, traffic policing (Traffic Policing), traffic shaping (Traffic Shaping), congestion management, Congestion Avoidance etc.
According to current 3GPP technical specification, its end to end IP QoS implement in the block data protocol context (PDP Context) between core net and UE, in UTRAN, do not have the enforcement point of direct IP QoS.UTRAN is to the support of IP QoS, be IP QoS to be converted to RAB QoS (RAB QoS) by core network, again by UTRAN chain of command Radio Resource control (Radio ResourceControl, RRC) be converted to radio bearer QoS (RB QoS) and realize, comprise the attribute of characteristic, transmission channel and physical channel of the RLC/MAC entity of radio bearer correspondence.For example: adopt dissimilar RLC entity (retransmit or do not retransmit), the different transmission channel of application to transmit, give different priority of logical channels etc. to different IP messages, this also can support IP QoS to a certain extent.But the RLC/MAC entity can't the process IP head, also just can't resemble to implement corresponding qos policy at 5 tuples (source address, destination address, source port, destination interface, protocol number) of IP and other fields of IP head traditional IP qos policy.
Said method is before 3GPP Release 5, utilize dedicated channel to transmit all right fine support IP QoS under the situation of IP grouping in the system, but after Release 5, WCDMA and TD-SCDMA system have increased high speed downlink packet and have shared access (High Speed Downlink Packet Access, HSDPA), adopt high-speed downlink shared transmission channel (High Speed Downlink Shared Channel, HS-DSCH) transmit IP message, and shared channel is to be shared by all UE in the same sub-district to use, be based on the scheduling of the IP message in the whole sub-district, and its bandwidth is constantly to change, and this just need carry out direct IP qos policy with control with manage contention on the shared channel, congested and flow (the most important thing is Congestion Avoidance and traffic shaping).But when the MAC entity is shared transmission channel in scheduling, can only carry out congested control afterwards, not realize Congestion Avoidance according to the radio bearer information of configuration.This is because the MAC entity be can't see the IP head, also just can't judge type of service, can't implement the IPQoS strategy at the IP loaded service, so the MAC entity is when dispatching, can only dispatch and congestion management according to the priority query of shared channel, but the number of priority query is very limited (having defined 8 formations among the current 3GPP), does not satisfy the needs of professional expansion.
In current 3GPP agreement, unique PDCP entity that can the process IP head does not comprise IP QoS support function among the UTRAN, and the PDCP entity is based on the radio bearer rank implementation agreement function in the single UE, and the IP QoS that can't carry out cell level supports.3GPP is placed on core network fully to the enforcement of IP qos policy now, also just can't cooperate the state variation of wireless sharing channel to carry out the enforcement of qos policy.
UTRAN may be with the data of carrying all-IP in the future, if lack the full implementation of direct IP qos policy, needs are carried out IP QoS to the conversion between the radio bearer QoS (RB QoS), this conversion, along with the expansion of IP bearer service, it is more and more difficult to become.Especially on shared channel,, can't realize Congestion Avoidance and traffic shaping function owing to can not treat with a certain discrimination at IP header (business information).This will influence the support to IP of WCDMA and TD-SCDMA system.
In sum, prior art does not have the enforcement point of IP QoS in UTRAN, can't directly implement the IP qos policy, can't implement the IPQoS strategy of cell level.Even carrying out complicated IPQoS also can't satisfy traffic shaping, Congestion Avoidance fully and treat requirement with a certain discrimination to the conversion of RBQoS.

Embodiment
The inventive method is applied in the wireless access subsystem of mobile communication system, and described wireless access subsystem comprises that Wideband Code Division Multiple Access (WCDMA) inserts the UTRAN of WCDMA or TD SDMA access TD-SCDMA system.
The inventive method comprises: will send to the IP message of mobile subscriber terminal, and send to the user entity of wireless access subsystem, and implement IP QoS control according to the IP QoS service model of selecting to receiving the IP message by user entity.Also comprise by core net and send the chain of command of the signaling message of IP qos policy to the wireless access subsystem, the QoS Control Parameter of carrying in the signaling message is converted to the transmission parameter of the wireless channel of user's face correspondence by chain of command, and utilize this transmission parameter to configure corresponding wireless channel, use the IP message of the wireless channel carrying reception that configures.
In embodiments of the present invention, adopt integrated service intserv model to carry out IP QoS control with the chain of command entity RRC among the UTRAN, and by user entity PDCP layer realization DiffServ/ multi protocol label exchange (Multiprotocol Label Switching, MPLS) etc. the QoS model of type is an example, and the inventive method is described in detail.
Referring to Fig. 2, the specific implementation method of intserv model is: the signaling message (protocol signaling of resource reservation) of the IntServ that core net sends is passed to the RRC protocol entity of UTRAN chain of command by core net, carries the QoS Control Parameter in the signaling message; The RRC protocol entity is converted to radio bearer configuration parameter (transmission parameter of wireless channel) with the parameter in the PSVP signaling, and by control Service Access Point (Service Access Point, SAP) interface, the operational factor of controlling each protocol entity (comprising PDCP, RLC, MAC, PHY) disposes this radio bearer, the radio bearer that utilization configures transmits corresponding IP message, thereby implements intserv model.
Models such as DiffServ model or MPLS are implemented by the PDCP layer of UTRAN user's face.In embodiments of the present invention, the PDCP layer is divided into two sublayers of sub-district PDCP-CELL and user PDCP-UE.The PDCP-CELL sublayer is responsible for the IP qos policy of whole cell level and is implemented, and carries out congested control and management, traffic policing and the strategies such as shaping, queue scheduling of the IP transmission channel (shared channel and common signal channel) of cell level; Other IP QoS control of UE level is also carried out in the PDCP-UE sublayer except realizing IP header suppression, SRNC reorientation and the transmission of IP message on radio bearer.Specific implementation process is as follows:
(1), all send to the IP message of all UE in the sub-district, arrive the PDCP-CELL sublayer earlier after entering UTRAN.
(2), the PDCP-CELL sublayer obtains each field in the IP head in each IP message value of (comprising source address, destination address, source port number, destination slogan, transport layer protocol number, priority etc.) according to selected IP QoS model (DiffServ model or MPLS etc.), corresponding QoS algorithm parameter according to configuration, algorithm according to appointment calculates qos value; With the result calculated value, be input to IP QoS decision parameter and calculate court verdict in the decision algorithm, according to court verdict the IP message that receives is implemented respective handling; For example: with the IP packet loss that receives or the priority that determines its transmission or decision to source address feedback-related information or the like.
Configuration for QoS algorithm parameter and decision parameter, realize by the control SAP interface function between expansion RRC protocol entity and the PDCP-CELL sublayer in the present invention, promptly at RRC in the configuration information that the PDCP layer sends, increase and carry out QoS calculating and judgement corresponding parameters information, send in PDCP-CELL and the PDCP-UE sublayer by control SAP interface.The configuration of QoS algorithm parameter and decision parameter also can be passed through the operation and maintenance system, and (Operation and Management OAM) is configured in the PDCP-CELL sublayer.
(3),, send to corresponding formation in the corresponding PDCP-UE sublayer according to the purpose UE and the court verdict of message if the PDCP-CELL sublayer determines the IP message of current reception not abandon.Realize IP header suppression, SRNC reorientation and the transmission of IP message on radio bearer by the PDCP-UE sublayer, also realize other IP QoS control of UE level, concrete IP QoS control method is identical with the method that cell-level IP QoS control is carried out in above-mentioned PDCP-CELL sublayer, comprising:
The PDCP-UE sublayer obtains each field in the IP head in each IP message value of (comprising source address, destination address, source port number, destination slogan, transport layer protocol number, priority etc.) according to selected IP QoS model (DiffServ model or MPLS etc.), corresponding QoS algorithm parameter according to configuration, algorithm according to appointment calculates qos value; With the result calculated value, be input to IP QoS decision parameter and calculate court verdict in the decision algorithm, according to court verdict the IP message that receives is implemented respective handling.Concrete processing policy is for example: with the IP packet loss that receives or the priority that determines its transmission or decision to source address feedback-related information or the like.Do not abandon if processing policy is a message, then send the IP message that receives to user terminal by Radio Link control rlc protocol entity, media access control MAC protocol entity and radio physical layer PHY entity.
The IP QoS model of the IP QoS model that above-mentioned PDCP-UE sublayer is selected and the selection of PDCP-CELL sublayer can be identical also can be inequality; In like manner, the PDCP-UE sublayer selected IP QoS model of each user terminal correspondence also can be mutually the same or inequality.
In order to implement the IP qos policy at the PDCP layer better, the present invention has increased the control SAP interface of MAC layer to the PDCP-UE sublayer.The MAC layer is by this control SAP interface, IP message from each UE to the PDCP-UE sublayer that report at shared channel or/and the transmission information on the common signal channel (comprising information such as average bandwidth, average delay, individual time delay, average error rate, individual error rate).The PDCP-CELL sublayer is given with these transmission report information again in the PDCP-UE sublayer.PDCP-CELL sublayer and PDCP-UE sublayer calculate qos value according to the QoS algorithm parameter of RRC configuration and the transmission information of reporting in conjunction with the MAC layer, are used for QoS control.
From above QoS control flow as can be known, the PDCP layer arrives UE with the IP packet data exchanged that core-network side enters, and carries out the control and the management of packet switching in this exchange process, promptly realizes IP QoS control.
Because the DiffServ model among the IP QoS can provide congested control and management, traffic shaping and functions such as supervision, queue management, can avoid the congested and blindness of IP message on HSDPA to abandon better, and can carry out priority management and scheduling of resource better, thereby make that the HSDPA bearer IP service is more efficient.Therefore implement function by direct IP QoS in UTRAN, UTRAN can be based on the transmission of IP loaded service type management IP message on shared channel, can make IP Qos algorithm in time adapt to the variation of wireless channel, also make HSDPA support the IP Packet Service better, guarantee that UTRAN can carry the all-IP business.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
