Abstract
The invention provides a method for deleting personnel in a multi-tunnel routeset and a super movable broadband system. In the method for deleting, evolution base stations eBS1, eBS2 and SRNC are personnel in a routeset of an accessed terminal, wherein the eBS1 and the accessed terminal are in a connected state, and the eBS1is used for sending forward chain data to the accessed terminal and transmitting a data packet of the accessed terminal to the eBS2. The method includes the following steps: the personnel eBS2 is deleted from the routeset of the accessed terminal; the eBS2 judges whether a basic agent IP tunnel exists between the eBS2 and an accessed gateway; and if the basic agent IP tunnel exists between the eBS2 and the accessed gateway, then the basic agent IP tunnel is remained. The invention perfects the functions of a route management set.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of delet method and system of personnel in multi-tunnel routeset.
Background technology
UMB (Ultra Mobile Broadband, Ultra-Mobile Broadband) then is the new technology of cdma2000 access technology evolution.Many technology of UMB air interface can promote the performance of cdma2000 inserting technology networks greatly, have established nature basis for the user provides the radio multimedium business of more requirements at the higher level.
Route (route) and Access Network route instance concepts have been introduced in the UMB air interface technologies; Route is meant the protocol stack (InUse protocol stack) that accesses terminal and using with an Access Network, and an Access Network route instance refers to and access terminal one open the logicality function of route.In realization, a route instance can be an evolution base station (eBS, evolved Base Station), also can be session reference network control (SRNC, Session Reference Network Control) entity.Set of routes then is meant the set of all the route instances that had of accessing terminal.
The use of set of routes allows to have between the quick eBS that can seamlessly move and simplify widely the low expense of eBS interface support between the adjacent eBS of different abilities switches, access terminal through route manage with set of routes in relevant processing and the operation of each eBS.The management of set of routes comprises increases the set of routes member, deletion set of routes member.
In the UMB network technology, (AGW is through setting up proxy-mobile IP tunnel (being referred to as PMIP Tunnel or Proxy Mobile IP Tunnel) contact with transmitting grouped data between AccessGateway) for evolution base station and IAD.Can there be the proxy-mobile IP tunnel in an IAD with a plurality of evolution base stations, and this is referred to as many tunnels.The evolution base station that receives the forward link user data from IAD is referred to as data binding point (DAP, Data Attachment Point), and DAP can be in set of routes, also can be not in set of routes.
In addition; Feedforward network evolution base station (FLSE; Forward Link Serving eBS) is meant with AT and keeps being connected, and send the evolution base station of forward link data, oppositely network evolution base station (RLSE to AT; Reserve Link Serving eBS) is meant that maintenance is connected with AT, sends the evolution base station of AT packet to DAP.Under normal conditions, AGW sends to DAP with data through basic PMIP tunnel, and DAP sends to forward direction service evolution base station to forward data again.
In current set of routes member deletion technology; For a plurality of PMIP tunnel flow process as shown in Figure 1 or mode of operation are arranged: suppose that evolution base station eBS1, eBS2 and SRNC are in set of routes; And eBS1 and eBS2 have data tunnel with AGW respectively, just the PMIP tunnel.
Step is following:
A. access terminal AT current with set of routes in eBS1 have and be connected, eBS2 and SRNC are other members of set of routes;
There are basic PMIP tunnel (representing with cylindricality in the drawings) in b.eBS1 and AGW, and in this example, eBS1 also bears the function of DAP simultaneously.User data transmits in AT and eBS1/DAP and AGW;
Only there are reverse tunnel (representing with cylindricality in the drawings) in c.eBS2 and AGW;
D. the route instance (eBS2) or the transmission route close message (RouteClose) that accesses terminal are with removing members eBS2 from set of routes.
E. accessing terminal keeps and the connected state of eBS1, and SRNC continues to be retained in the set of routes;
F. in the deletion route that accesses terminal, AT sends route and shines upon (Route Map) message to all members in the set of routes, to upgrade all the route instances in the set of routes.Shine upon message according to this route, eBS1 and SRNC stop all communications with eBS2;
G. after completion and all communications, eBS2 sends the PMIP-login request message with the PMIP tunnel between deletion and the AGW.Carrying life cycle in this message is 0;
H. receive after this message, the data tunnel between AGW deletion and the eBS2, and send PMIP-registration reply message and give eBS2;
I.eBS1 continues and AGW keeps basic tunnel;
J. after eBS2 receives the route close message; Perhaps it connects after maintenance lifetime (the Connection Keep Alive Period) timer expiry; If at eBS2 any airlink record of creating for AT is arranged, eBS2 sends charging request message and gives AGW;
K. receive after the charging request message that AGW sends charge response message and gives eBS2.When charging report obtains the affirmation of AGW, eBS2 cancels to AT and distributes all resources.
In above-mentioned flow process, obviously eBS1 is a forward direction service evolution base station, and the function of serving as DAP, because there is basic PMIP tunnel in it with AGW.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem: in the actual operation, forward direction service evolution base station and DAP possibly not be evolution base stations.As the member of DAP as the Route collection, it also can be deleted from set of routes, because along with the distance of forward direction service evolution base station and DAP more and more far is moved out of set of routes.But DAP is bearing and is keeping the function in basic PMIP tunnel with AGW and can not discharge immediately.Therefore on, above-mentioned flow process be actually can't solve when DAP as Route collection member and the situation of being deleted.
Summary of the invention
The present invention aims to provide a kind of delet method and system of personnel in multi-tunnel routeset, with solve when DAP as Route collection member and the problem of the situation of being deleted.
