Description
Technical field
The present invention relates to moving communicating field, relate in particular to paging method and radio network controller and IAD in the mobile communication system.
Background technology
At present, global radio communication is just presenting the trend of mobile, broadband and IPization.Broadband wireless access develops to mobile communication technology to mobile and has brought direct competitive pressure.Therefore 3GPP and 3G,PP2 two big 3G (Third Generation) Moblie standardization bodies have successively begun the technical research and the standardization effort of the evolved system of 3G (E3G), with the competitiveness of maintenance 3G technology with in the leadership of moving communicating field.
The AIE work of 3GPP2 is divided into Phase1 and two stages of Phase2, wherein Phase1 finishes multicarrier HRPD (HRPD-High Rate Packet Data, HRPD (high rate packet data)) be NxEV-DO, main target is to improve peak data rate and keep backward compatibility.The technical standard EV-DO Rev B of Phase1 formally promulgation at present.The peak data rate target in Phase2 stage is the different mobility of forward link foundation, can support 100Mbps～500Mbps; Reverse link is supported 50Mbps～150Mbps, reduces system's time delay simultaneously.Phase2 is UMB (Ultra Mobile Broadband, a super mobile broadband) by CDG (CDMA Development Group, code division multiple access promotes association) definite designation, and the UMB1.0 standard is issued.The network architecture that matches with UMB tentatively is determined, and has provided among Fig. 1 in this network configuration and metadata cache, network entity and interface that paging is relevant.
Referring to Fig. 1, be UMB network reference framework model schematic diagram in the prior art.Comprise EBS (Enhanced Base Station with metadata cache, entity that paging is relevant among Fig. 1, the enhancing base station), SRNC (Signaling Radio Network Controller, signaling wireless network controller) and AGW (AccessGateway, IAD).
EBS is the base station of evolution, and its major function comprises: support the UMB technology of eating dishes without rice or wine, finish enciphering/deciphering and integrity protection at link layer, the compression of IP packet header, and function such as QoS scheduling.EBS is direct process IP message, has embodied the marginalisation trend of IP.
The function of SRNC comprises: access authentication, the session information between storage AT (Access Terminal accesses terminal, and comprises the terminal of using among the HRPD) and EBS, paging function, the management of terminal Idle state etc.
AGW is first jumping that terminal is connected to the IP operation net, and it finishes functions such as IP operation authentication, charging, local mobile management, QoS management.Terminal and internetwork user face data transmit by EBS and AGW, compare that data surface need pass through AN (Access Network in the EVDO technology, access network equipment), PCF (Packet Control Function, the packet data control function), PDSN (Packet DataSupport Node, packet data support node) three nodes, reduce data surface processing node number, helped reducing the data surface propagation delay time, improved efficiency of transmission.For realizing that user data wraps in the transmission between EBS and the AGW, need set up a data tunnel for the user between the two.This tunnel of hypothesis adopts the tunnel of PMIP (Proxy MIP, proxy-mobile IP) at present.
Prior art also provides the paging flow process based on the above-mentioned UMB network architecture.
Referring to Fig. 2, in the prior art based on one of paging flow process of the UMB network architecture.In page-mode shown in Figure 2, EBS bears data cached function as DAP (Data Attachment Point, data attachment point).When AT was in state of activation, AGW sent data to EBS by the PMIP tunnel, and EBS sends to AT with data.When AT inserts idle condition, execution in step:
Step 2, receive target ip address for sending to EBS after the packet of this AT, by the data of this AT of EBS buffer memory as AGW.
Step 3, EBS notice SRNC initiate the paging at this AT.
Step 4, SRNC send to EBS and seek request message (Paging Request), this AT of paging.
Step 5, EBS send beep-page message, this AT of paging.
Behind step 6, the AT response beep-page message, eat dishes without rice or wine to be connected with EBS foundation.After this, AT just can receive data cached from EBS, or carries out transfer of data by EBS and AGW.
In the page-mode shown in Figure 2, may cause data out of order on EBS metadata cache, this is a reason: AT may leave and discharge the EBS that connects, and data still are buffered on the original EBS.After connecting when AT response paging and with new EBS, new data send to new EBS by newly-established PMIP tunnel, and the data that are buffered in former EBS need be forwarded.New data might be sent to terminal earlier than data in buffer, thereby cause data out of order.The quality of service of the real time business that the out of order infringement time-delay of data is responsive.
In addition, metadata cache may be caused the triangle route on EBS, this be because: when still using original PMIP tunnel of this terminal, data arrive original EBS from AGW by former PMIP tunnel, arrive new EBS again, sent to terminal at last, form the triangle route.The triangle route will increase time-delay, consume extra transmission bandwidth and disposal ability.
Referring to Fig. 3, in the prior art based on two of the paging flow process of the UMB network architecture.In page-mode shown in Figure 3, bear data cached function by AGW.When AT was in state of activation, AGW sent data to EBS2 by the PMIP tunnel, and EBS2 sends to AT with data.When AT inserts idle condition, execution in step:
Step 2-3, if AT moves to EBS1, then register and location registers to SRNC, SRNC moves to this AT the information notice EBS2 of EBS1.
Step 4, EBS2 trigger the data of this AT of AGW buffer memory.
Step 5, receive target ip address for the laggard row cache of packet of this AT and notify EBS2 as AGW.
Step 6, EBS2 notice SRNC initiate the paging at this AT.
Step 7, SRNC send to each EBS and seek request message, this AT of paging.
Step 8, each EBS are by this AT of paging that eats dishes without rice or wine.
The beep-page message of step 9, AT response EBS1 eats dishes without rice or wine to be connected with EBS1 foundation.
Set up the PMIP tunnel for AT between step 10, EBS1 and AGW.After this, this AT just can carry out transfer of data by EBS1 and AGW.
In the page-mode shown in Figure 3, when the terminal of paging Idle state, AGW triggers SRNC by EBS and initiates paging, and processing procedure is more, has increased network delay.
Prior art can also combine above-mentioned two kinds of page-modes, adopts page-mode shown in Figure 2 when the AT moving range is little, when the terminal moving range is big, adopts page-mode shown in Figure 3.But this mode causes the logic of paging very complicated, needs to judge the scope that AT moves decides which kind of pattern of use, has therefore reduced system effectiveness.
