Description
Technical field
The present invention relates to the mobile communications network access technology, refer to especially a kind of in evolvement network (EvolvedNetwork), the method for quickly activating moving platform (MS).
Background technology
Universal mobile telecommunications system (UMTS) is a kind of third generation cordless communication network technical standard of third generation partner program (3GPP) tissue definition.The UMTS network is made up of core net (Core Network) and UTMS land radio access web (UTRAN, UMTS Terrestrial Radio Access Network).Core net comprises circuit domain (CS, Circuit Switch) and two parts of packet domain (PS, Packet Switch), wherein, circuit domain provides based on Circuit-switched business such as speech business, and packet domain provides business such as internet (Internet) visit based on packet switching.The terminal that the user uses in the UMTS network is subscriber equipment (UE, User Equipment).
Fig. 1 is the schematic network structure of prior art UMTS, as shown in Figure 1, because this paper only relates to the packet domain part, therefore the circuit domain part is not shown in Figure 1 in the core net, and core net is made up of Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN) and attaching position register (HLR); Access Network is made up of radio network controller (RNC) and base station node B.UE is mutual by carrying out between Uu interface and NodeB, and each RNC can connect some NodeB, and each SGSN can connect some RNC.Be to be to be between Iu interface, SGSN and the GGSN between Gn/Gp interface, SGSN and the HLR between Iub interface, RNC and the SGSN between NodeB and the RNC for being Gc interface, GGSN and outside packet data network (PDN between Gr interface, GGSN and the HLR, Packet Data Network) be the Gi interface between, PDN is meant the general name of all packet data network herein, and PDN can be Internet network or enterprise network or the like.
Wherein, the Uu interface is the air interface of UMTS network.Physical layer (PHY or L1) agreement is positioned at NodeB, belongs to the ground floor agreement of Uu interface; Medium access control (MAC) agreement, Radio Link control (RLC) agreement, packet data convergence protocol (PDCP) and broadcast/multi broadcast control protocol (BMC, Broadcast/Multicast Control) are positioned at RNC, belong to the second layer agreement of Uu interface; RRM (RRC) agreement is positioned at RNC, belongs to the 3rd layer protocol of Uu interface.The PHY agreement mainly finish physical channel processing, transmit and receive physical channel; The main completion logic channel of MAC agreement is to the mapping and the scheduling feature of transmission channel; Rlc protocol is mainly finished the segmentation/reorganization of data and is retransmitted; PDCP mainly finishes the sequence number of IP the compression/de-compression and the service data of data; The BMC agreement is mainly finished the buffer memory and the scheduling of cell broadcast messages; And the RRC agreement is the core of Uu interface, and the RRC agreement is responsible for the management of Radio Resource, finishes configuration and control to lower-layer protocols PHY/MAC/RLC/PDCP/BMC.
The Iu interface is the key interface of Access Network and core net, and the management of Radio Resource and control are isolated in the Access Network by the Iu interface, makes core net that professional providing only is provided.
In the UMTS network, the transmission bearer of Uu interface is radio bearer (RB, Radio Bearer), and the transmission bearer of Iu interface is RAB (RAB, Radio Access Bearer).In fact a RB is exactly one group of PDCP and RLC, and a RAB is in fact corresponding to a GPRS tunnel User Agreement (GTP-U, GPRS Tunneling Protocol-User) entity, the GTP-U agreement is present in RNC, SGSN and GGSN, is used to finish the tunnel encapsulation and the transmission of IP grouped data.Wherein, RB is present among RNC and the UE, and promptly RNC and UE have PDCP and rlc protocol entity.When business was set up in the UE request, RNC was PDCP and RLC according to the requirement of business for UE creates and dispose RB in RNC, and the QoS configuration data of RB is provided by the RRC protocol entity on upper strata.In addition, RRC also needs to provide for UE the QoS configuration parameter of RB among the RNC, and these QoS configuration parameters are passed to UE by the RRC signaling message, and UE creates and dispose RB according to the QoS configuration parameter in UE.Because the asymmetry of Packet Service, such as network to the downstream rate of UE usually than the upstream rate height of UE to network, cause the QoS of uplink and downlink there are differences, so the QoS configuration parameter of the RB among RNC and the UE there are differences.
At present, 3GPP is studying the next generation network after the evolution of UMTS network, and formulates the technical standard of evolvement network, the next generation network after the evolution of UMTS network is abbreviated as evolvement network (Evolved Network) herein.Evolvement network will have a lot of new characteristics, such as: the packet-type business only is provided, and real time business such as voice, visual telephone also adopt the mode of grouping to realize; Realize complete IP network, each node interconnects by IP network in the network, and each portable terminal adheres to distributing IP address, back; Switching and roaming between support and the UMTS network.In addition, evolvement network was had higher requirement to the time of inserting and switch: the time that user access network enters activated state is no more than 200ms; Be no more than 300 milliseconds switching time between the system of real time business; Be no more than 500 milliseconds switching time between the system of non-real-time service; The support fastext activates, and the activationary time from the idle condition to the state of activation is not less than 100ms etc., and as seen, evolvement network is the comparison harshness to the time requirement of quick access.
Fig. 2 is the structural representation of the evolvement network of present 3GPP definition, and this evolution network structure is not also finally determined.As shown in Figure 2, evolvement network comprises evolution block core net (Evolved Packet Core) and evolution wireless access network (Evolved-RAN, Radio Access Network).Wherein, three logical functional entities are arranged among the EvolvedPacket Core, Mobility Management Entity (MME, MobilityManagement Entity), user entity (UPE, User Plane Entity) anchor point (IASA and between connecting system, Inter AS Anchor), MME is used to realize mobile management, UPE is used to realize the processing of packet sessions management and user plane packets data, and Inter AS Anchor is used to realize the access of evolvement network and outside PDN, switching between evolvement network and other non-3GPP network such as the wireless lan (wlan) and roaming etc.; Evolved-RAN mainly provides wireless air interface such as wireless channel, and relevant function such as power control, the RRM etc. of Radio Resource.Interface between Evolved RAN and the Evolved Packet Core is the S1 interface, and the interface between Evolved Packet Core and the outside PDN is the Gi interface.Among Fig. 2, MME and UPE are incorporated in a physical equipment, and MME also can belong to different physical equipments with UPE.S1 here and Gi just represent a kind of interface relationship, and the concrete title of interface is determined by 3GPP.
In addition, herein, the terminal equipment unification that user in the evolvement network is used is called travelling carriage (MS, Mobile Station).MS has two states: idle (Idle) attitude and activation (Active) attitude.When MS carries out network registry, be in activated state,, then be discharged into Idle state by activated state if there is not transfer of data; When having transfer of data or other signaling activity such as position renewal activity between MS and the network again, MS is moved to activated state by Idle state again.Under Idle state, only MME/UPE has the contextual information of MS, and MS is assigned the IP address and keeps default IP carrying.Under activated state, Evolved-RAN has the contextual information of MS, and MS is assigned radio channel resource, transmitting grouped data and signaling message at any time between MS and the network.
Herein, the transmission bearer of evolvement network air interface still is called RB, and the carrying of evolvement network S1 interface still is called RAB.Though MAC, RLC, PDCP agreement will change in the evolvement network, be positioned at Evolved Packet Core etc. such as RLC and MAC merging, PDCP, but radio bearer RB and RAB still are illustrated respectively in a group or a protocol entity that is used to transmit upper layer data on air interface and the S1 interface.
In evolvement network, after the mobile platform started, can search for and select network earlier and carry out network attachment; After successfully being attached to evolvement network, travelling carriage could use professional.Network attachment is exactly the process of mobile station login to evolution block core net, and in the network attachment process, evolvement network carries out authentication to travelling carriage, creates communication context information, distributes temporary mark and IP address, sets up default IP carrying for travelling carriage then.Default IP carrying is mainly used in the IP of " always online " is provided Packet Service, and transmission is to the user data of the business game and the no specific (special) requirements of chargeing, such as the business that need not charge, IP-based IP multimedia subsystem, IMS (IMS) register command data etc., in case evolvement network is finished the authentication to MS, default IP carrying just is established.Fig. 3 is the flow chart of network attachment in the evolvement network, specifically may further comprise the steps:
Step 300:MS start back is found network and is selected network.
If MS finds plurality of network, such as UMTS network, evolvement network, MS can select suitable network.How to select network not belong to category of the present invention, be not described in detail here.
Here suppose that MS has selected evolvement network.
Step 301:MS sends Attach Request message to MME/UPE.
At least carry the sign of MS and the sign of MS place tracking area in this Attach Request message.Attach Request message is routed to MME/UPE by Evolved-RAN.
The sign of MS can be permanent sign such as the IMSI International Mobile Subscriber Identity (IMSI) of MS, the perhaps temporary mark of MS such as packet TMSI (P-TMSI).If MS has temporary mark, then should use temporary mark.
Step 302: home subscriber server (HSS) and MME/UPE carry out authentication to MS.
HSS belongs to the existing network entity, how to realize that authentication does not belong to category of the present invention, is not described in detail here.Here suppose the authentication success.
Step 303:MME/UPE sends login request message to HSS.
At least carry the sign of MME/UPE in this login request message.
Information in the step 304:HSS storage login request message, for example the sign of MME/UPE is replied registration confirmation message to MME/UPE then.
The subscription data of portability user in HSS in this registration confirmation message.
After MME/UPE receives registration confirmation message from HSS, obtain also storage user's subscription data, the qos parameter of default IP carrying is provided in the subscription data, and to require network be that MS sets up default IP carrying.
Step 305: after being accomplished to the registration of HSS, between MME/UPE and Inter AS Anchor, setting up default IP carrying, setting up RB between MS and the Evolved-RAN, between Evolved-RAN and MME/UPE, setting up RAB.
In this step, MME/UPE or Inter AS Anchor are that MS distributes temporary mark and IP address, sets up default IP carrying between MME/UPE and Inter AS Anchor, setting up RB between MS and the Evolved-RAN, sets up RAB between Evolved-RAN and MME/UPE.Like this, connect to having set up a default IP between the InterAS Anchor at MS, shown in two-way dotted arrow among Fig. 3.Specific implementation sees also the hereinafter description of Fig. 4.
MS can use this default IP to be connected transmission IP grouped data with Inter AS Anchor, and the IP grouped data is the grouping busihess data of application layer, or the session initiation protocol of the signaling data of application layer such as IMS (SIP) signaling etc.
Step 306:MME/UPE replys to adhere to MS and accepts message.
This adheres to temporary mark such as P-TMSI and the IP address of accepting to carry at least in the message MS.
Parameters such as the temporary mark accepting to carry in the message and IP address are adhered in travelling carriage storage, and reply to MME/UPE and to adhere to acknowledge message, indicate new temporary mark or IP address to be used.
So far, MS successfully is attached to evolvement network, has obtained temporary mark and IP address.
After MS completes successfully network attachment, if MS has the IMS ability and the user need use the IMS business, MS will carry out the IMS registration.In the IMS registration process, all IMS signaling messages connect by the default IP that sets up in the step 305 and transmit.
After MS carries out network attachment and IMS registration, if default RB and the transmission of default RAB free of data, default RB and RAB will be released, but the default IP carrying between MME/UPE and the IASA is retained.After the release, the communication context information of MS in Evolved-RAN is deleted, for all resources that MS distributes, comprise that radio channel resource and transmission bearer resource are released, MS is in Idle state, but the IP address of MS remains unchanged.
Among Fig. 3, step 305 realizes default IP establishment of connection, default IP connects by three parts and forms: the RAB of S1 interface between the RB of air interface, Evolved-RAB and the MME/UPE between MS and the Evolved-RAN, and the default IP of interface carries between MME/UPE and the Inter AS Anchor.The foundation of RB and RAB is initiated by MME/UPE usually, MME/UPE indicates service quality (QoS) parameter of default IP carrying to Evolved-RAN by service provisioning, by Evolved-RAN the qos parameter of default IP carrying is mapped to the QoS configuration parameter of RB and RAB, Evolved-RAN is that MS distributes radio channel resource according to the qos parameter of default IP carrying also.Fig. 4 is in the evolvement network, and Evolved-RAN is that default IP connects the flow chart of setting up RB and RAB, as shown in Figure 4, MME/UPE receive from HSS reply registration confirmation message after, the specific implementation of setting up RB and RAB may further comprise the steps:
Step 400:MME/UPE sends assignment request message to Evolved-RAN, carries the qos parameter of default IP carrying in this assignment request message at least.
Wherein, include the qos parameter of default IP carrying in the user's of MME/UPE storage the subscription data.
The qos parameter that step 401:Evolved-RAN carries the default IP that carries in the assignment request message is mapped to the QoS configuration parameter of RB and RAB, and distributes radio channel resource.
After Evolved-RAN receives assignment request message, at first admit control, judge that promptly can current resource satisfy the quality of service requirement of the qos parameter of the default IP carrying of carrying in the assignment request, if can satisfy, then shines upon; Otherwise, the assignment request of refusal MME/UPE, default IP connects the foundation failure.
Here, the QoS configuration parameter of RB comprises the QoS configuration parameter two parts of RB among the QoS configuration parameter of RB among the Evolved-RAN and the MS.
Described qos parameter mapping method can belong to prior art referring to 3GPP TS25.331 and TS25.413 standard, repeats no more here.
Obtain the QoS configuration parameter of RAB between step 402:Evolved-RAN and the MME/UPE according to mapping, set up the RAB of S1 interface.
Obtain the QoS configuration parameter of RB between step 403:Evolved-RAN and the MS according to mapping, set up the RB of air interface.
In this step, the QoS configuration parameter of the default RB that Evolved-RAN can distribute for MS is indicated to MS by signaling message.MS and Evolved-RAN create and configuration RB separately according to the QoS configuration parameter of RB among the QoS configuration parameter of RB among the Evolved-RAN and the MS respectively.
Need to prove that there is not strict sequencing in the execution of step 402 and step 403, promptly step 403 also can be carried out before step 402.
Step 404:Evolved-RAN replys assignment to MME/UPE and finishes message, indicates default IP to carry needed RB and RAB and has set up and finish.
So far, MS sets up to the default IP successful connection between the Inter AS Anchor, can be used for transmitting/downlink grouped data.
Need to prove, Fig. 4 is an indicative flowchart of setting up RB and RAB in the general evolvement network of present industry, final flow chart and the Fig. 4 that adopts of evolvement network may there are differences, but, in order to set up RB and RAB, Evolved-RAN must be mapped to the qos parameter of default IP carrying the QoS configuration parameter of RB and RAB.
Above-mentioned QoS configuration parameter is meant the configuration parameter of concrete protocol entity, such as the configuration parameter of MAC, the configuration parameter of PDCP and the configuration parameter of GTP-U etc.If the S1 interface does not use the GTP agreement, and use other tunnel protocol, such as Generic Routing Encapsulation (GRE, Generic RoutingEncapsulation) tunnel protocol gre tunneling agreement, then the QoS configuration parameter of RAB is exactly the configuration parameter of the tunnel protocol entity that refer to use such as the configuration parameter of gre tunneling agreement.
At present, when MS is in Idle state, if default IP carries downlink data transmission, such as, because of calling out, IMS cause the SIP signaling message need send to MS, and the SIP signaling message will send to MME/UPE as the IP grouped data, MME/UPE meeting paging MS; MS responds paging after receiving paging, and moves to activated state, at this moment, need rebulid default IP and connect required RB and RAB, and Fig. 5 is the flow chart of the activation MS that downlink business causes in the evolvement network, as shown in Figure 5, may further comprise the steps:
Step 500～when step 502:MS was in Idle state, MME/UPE was that MS has kept the default IP carrying to IASA, shown in two-way dash-dot arrows among Fig. 5.When default IP carried the downlink grouped data transmission, downlink grouped data was passed to MME/UPE by this default IP carrying;
The downlink grouped data that the MME/UPE buffer memory is received, and ask the paging of Evolved-RAN initiation to MS, Evolved-RAN is broadcast paging messages in the band of position at MS place;
After MS receives beep-page message, send page-response message to MME/UPE, this page-response message is routed to MME/UPE by Evolved-RAN.
Step 503:MME/UPE initiates assignment request message to Evolved-RAN, carries the qos parameter of default IP carrying in this assignment request message at least.
Step 504～step 507 is finished the QoS configuration parameter that the qos parameter of default IP carrying is mapped to RB and RAB by Evolved-RAN, Evolved-RAN is that MS distributes radio channel resource according to the qos parameter of default IP carrying also, set up RB and RAB, be connected thereby between MS and Inter AS Anchor, set up default IP.The specific implementation and the step 401～step 404 of step 504～step 507 are in full accord, no longer describe in detail here.As seen, when activating MS owing to paging, existing method need adopt the method for setting up RB and RAB process shown in Figure 4 again, is implemented in to set up default IP between MS and the Inter AS Anchor and be connected.
In addition, when MS is in Idle state, if MS need use default IP to connect and send ascending packet data, to initiate IMS such as MS and call out, the SIP signaling message need send to Inter AS Anchor, MS should be activated to activated state earlier, at this moment, need rebulid default IP and connect needed RB and RAB, Fig. 6 is the flow chart of the activation MS that uplink service causes in the evolvement network, as shown in Figure 6, may further comprise the steps:
Step 600～when step 601:MS was in Idle state, MME/UPE was that MS has kept the default IP carrying to IASA, shown in two-way dash-dot arrows among Fig. 6.When MME/UPE receives indication from MS when the access request message that needs MME/UPE to activate default IP carrying is arranged, initiate assignment request message to Evolved-RAN, carry the qos parameter of default IP carrying in this assignment request message at least.
Step 602～step 605 is finished the QoS configuration parameter that the qos parameter of default IP carrying is mapped to RB and RAB by Evolved-RAN, Evolved-RAN is that MS distributes radio channel resource according to the qos parameter of default IP carrying also, set up RB and RAB, be connected thereby between MS and Inter AS Anchor, set up default IP.The specific implementation and the step 401～step 404 of step 602～step 605 are in full accord, no longer describe in detail here.Equally, call out when activating MS initiating IMS owing to MS, existing method need adopt the method for setting up RB and RAB process shown in Figure 4 again, is implemented in to set up default IP between MS and the Inter AS Anchor and be connected.
The method of activation MS as seen from above-mentioned prior art, MS is under Idle state, in order to rebulid RB and RAB, Evolved-RAN must be mapped to the qos parameter of default IP carrying the QoS configuration parameter of RB and RAB, complicated qos parameter mapping, increase the processing time-delay of Evolved-RAN, caused MS to migrate to the increase of the activationary time of activated state from Idle state.Because evolvement network is the comparison harshness to the time requirement of quick access, if continue to adopt the existing method that rebulids RB and RAB to activate MS, can cause the time of MS access network longer, can not satisfy the harsh requirement that evolvement network proposed turn-on time.

Embodiment
Core concept of the present invention is: evolution block core net obtains default RB corresponding with default IP carrying and the QoS configuration parameter of default RAB by the network attachment of travelling carriage; When activating MS, the QoS configuration parameter of default RB that evolution block core net will obtain and default RAB sends to the evolution wireless access network; Default RB that the utilization of evolution wireless access network receives and the QoS configuration parameter of default RAB are set up default RB and default RAB, connect thereby set up default IP.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Among the present invention, will be used to carry RB and the RAB that default IP connects, be called default RB (DefaultRadio Bearer) and default RAB (Default Radio Access Bearer).
As long as the default IP carrying between MME/UPE and the Inter AS Anchor does not discharge, this default IP carrying just can not change the requirement of QoS, default RB corresponding with default IP carrying and the requirement to QoS of default RAB can not change yet, therefore, in the lifetime of default IP carrying, the QoS configuration parameter of default RB and default RAB can be repeated to use.The inventive method is utilized this point just, in default IP carries the lifetime, MME/UPE stores the QoS configuration parameter of default RB and default RAB, and when needs activate MS, MME/UPE offers Evolved-RAN with the QoS configuration parameter of default RB and default RAB, Evolved-RAN directly utilizes the QoS configuration parameter of this default RB and default RAB, sets up default RB and default RAB, connects thereby set up default IP.
Further, in the MS side, finish network attachment after, even MS is discharged into Idle state, MS discharges RB but keeps the QoS configuration parameter of default RB among the MS.When needs were rebuild default RB, the direct instruct MS of Evolved-RAN was used the QoS configuration parameter of the default RB of storage to set up default RB in MS and is got final product.
Need to prove, if when MS is discharged into Idle state, the QoS configuration parameter of default RB among the MS store M S, so, the QoS configuration parameter that MME/UPE stores default RB comprises the QoS configuration parameter of default RB among the Evolved-RAN; If when MS is discharged into Idle state, MS is the QoS configuration parameter of default RB among the store M S not, and so, the QoS configuration parameter that MME/UPE stores default RB comprises the QoS configuration parameter of default RB among the QoS configuration parameter of default RB among the Evolved-RAN and the MS.
Describe specific implementation method of the present invention in detail below in conjunction with Fig. 7.Fig. 7 is the flow chart of network attachment in the evolvement network of the present invention, as shown in Figure 7, compare with the flow process of network attachment in the described prior art evolvement network of Fig. 3, difference is: when default IP connection is set up, the newly-increased step that is used to preserve the QoS configuration parameter of default RB and default RAB is as the step 706 among Fig. 7.
In step 706, Evolved RAN reports the QoS configuration parameter of default RB and default RAB to MME/UPE, and MME/UPE stores from the default RB of Evolved RAN and the QoS configuration parameter of default RAB.
Need to prove that Evolved-RAN also can be when discharging default RB and default RAB, the QoS configuration parameter of default RB and default RAB is reported MME/UPE.
Further, because MS under Idle state, may move among the different Evolved-RAN, new Evolved-RAN may not use the default RB of MME/UPE indication and the QoS configuration parameter of default RAB.Be head it off, MME/UPE can do following processing:
The Evolved-RAN of self-management is classified and type identification is set at MME/UPE, such as, the Evolved-RAN that provides by same equipment vendor, be set to same type, have identical type identification, the Evolved-RAN that perhaps has identical or similar radio resource management function also can be set to same type etc.;
MME/UPE writes down the type identification of the Evolved-RAN at the current place of MS in the QoS configuration parameter of default RB of storage and default RAB.
Further, also can set up the default RB of self fast in order to make MS, the present invention can comprise step 709, specifically comprises: MS executes network attachment, and when being discharged into Idle state, MS discharges default RB but the QoS configuration parameter of default RB among the store M S.
From Fig. 7 as seen, evolution block core net is by the network attachment of travelling carriage, default RB corresponding and the QoS configuration parameter of default RAB have been obtained with default IP carrying, like this, when needs activated MS, default RB that evolution block core net only need obtain and the QoS configuration parameter of default RAB sent to the evolution wireless access network, default RB that the utilization of evolution wireless access network receives and the QoS configuration parameter of default RAB are set up default RB and default RAB gets final product.Fig. 8 is the flow chart that activates MS in the evolvement network of the present invention, as shown in Figure 8, suppose MS, when default IP carries downlink grouped data transmission or MS need use default IP to connect the transmission ascending packet data time at Idle state, need set up default RB and RAB, specifically may further comprise the steps:
Step 800:MME/UPE sends assignment request message to Evolved-RAN, carries the default RB of MME/UPE storage and the QoS configuration parameter of default RAB in this assignment request message.
Before step 800, if MME/UPE records the type identification of the Evolved-RAN at current MS place, so, the processing of MME/UPE further comprises: judge whether the Evolved-RAN of request and the Evolved-RAN with current MS corresponding stored of MME/UPE record belong to same type, if the Evolved-RAN with current MS corresponding stored that Evolved-RAN and the MME/UPE of request write down is identical or belong to same type, then MME/UPE only carries the QoS configuration parameter of default RB and default RAB in assignment request message; If the Evolved-RAN with current MS corresponding stored of the Evolved-RAN of request and MME/UPE record is inequality and do not belong to same class Evolved-RAN, then MME/UPE carries the QoS configuration parameter of qos parameter, default RB and the default RAB of default IP carrying simultaneously in assignment request message.
Need to prove if there is not the QoS configuration parameter of default RB and default RAB among the MME/UPE, also do not have the type identification of Evolved-RAN, then MME/UPE only carries the qos parameter of default IP carrying in assignment request message.Such as when the MS start is adhered to.
In addition, if carry the configuration parameter of qos parameter, default RB and the default RAB of default IP carrying in this assignment request message simultaneously, then Evolved-RAN ignores the qos parameter of default IP carrying.When Evolved-RAN sets up default RB and default RAB failure according to the QoS configuration parameter of default RB and default RAB, Evolved-RAN just uses the qos parameter of default IP carrying to be remapped to new default RB and the QoS configuration parameter of default RAB, sets up default RB and default RAB.
Default RB that carries in the assignment request message that step 801～step 802:Evolved-RAN utilization receives and the QoS configuration parameter of default RAB, set up default RAB, set up and dispose default RB among the Evolved-RAN, Evolved-RAN is that MS distributes radio channel resource.
In this step, if set up default RB or default RAB failure, and carry the qos parameter of default IP carrying in this assignment request message, then Evolved-RAN utilizes the qos parameter of default IP carrying, be mapped as the QoS configuration parameter of default RB and default RAB, set up and dispose default RB and RAB; If set up default RB and RAB failure, and do not carry the qos parameter of default IP carrying in this assignment request message, then Evolved-RAN sets up default RB and default RAB failure to the MME/UPE indication.
After step 803:Evolved-RAN successfully sets up default RAB according to the QoS configuration parameter of default RAB, send default RB to MS and activate Indication message, this default RB activates and carries Evolved-RAN in the Indication message is MS assigned radio resource configuration parameter.
Need to prove, if Evolved-RAN is the QoS configuration parameter that utilizes the default RB that the qos parameter mapping of default IP carrying obtains in step 801～step 802, set up and dispose default RB among the Evolved-RAN, then default RB activates the QoS configuration parameter that also should carry the default RB that is obtained by default IP bearer QoS parameters mapping in the Indication message.
Step 804:MS uses the QoS configuration parameter of default RB among the MS that stores to set up default RB, and utilizes default RB to activate the radio resource configuration parameters of carrying in the Indication message and set up wireless channel.
Need to prove that if the MS QoS configuration parameter of default RB among the store M S not, then the QoS configuration parameter of default RB sends to MS among the Evolved-RAN MS that needs simultaneously self is stored.
After step 805:MS successfully sets up default RB, respond default RB activation to Evolved-RAN and finish message, in MS, successfully set up to show default RB.
Step 806:Evolved-RAN sends assignment to MME/UPE and finishes message.So far, MS and Evolved-RAN have successfully set up default RB and default RAB.
Need to prove, if Evolved-RAN uses in step 801～step 802 is the default RB that obtains of default IP bearer QoS parameters mapping and the QoS configuration parameter of default RAB, then assignment is finished and also should be carried default RB that this mapping obtains and the QoS configuration parameter of default RAB in the message, MME/UPE utilizes the default RB receive and the QoS configuration parameter of default RAB, upgrades the default RB corresponding with current MS of self storage and the QoS configuration parameter of RAB.
From said method as seen, the evolution wireless access network directly utilizes the QoS configuration parameter of default RB and default RAB to set up default RB and default RAB, thereby setting up default IP connects, and will be not default the qos parameter of IP carrying be mapped to after the QoS configuration parameter of default RB and default RAB, set up default RB and default RAB again.Settling time of default RB and default RAB has been shortened in such processing, makes evolvement network connect needed default RB and default RAB for the MS of Idle state sets up default IP apace, thereby makes MS be activated to activated state from Idle state apace.In addition, if travelling carriage obtains to have the QoS configuration parameter of default RB, because the evolution wireless access network needn't provide the QoS configuration parameter of default RB to MS, simplified the signaling message that Evolved-RAN sends to MS.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
