Abstract
A method and apparatus for executing attachment procedures in a long term evolution (LTE) system to accommodate a single tunnel approach. Third Generation Partnership Program (3GPP) packet data protocol (PDP) context activation procedures are used for the allocation of an Internet protocol (IP) address and the establishment of tunneling between an evolved Node-B (eNodeB) and an anchor node, while allowing multiple radio access bearers (RABs) to be mapped to one PDP context for different quality of service (QoS) requirements. Thus, one PDP context is sufficient for a wireless transmit/receive unit (WTRU) within a single packet data network (PDN). Multiple PDP contexts can be established for special requirements, (e.g., bundled services), or when the WTRU connects to multiple PDNs.
Description
Technical field
The present invention relates generally to wireless communication system.More particularly, the present invention relates to a kind of method and apparatus that in third generation partner program (3GPP) system (just general packet radio service (GPRS) and Universal Mobile Telecommunications System) and Long Term Evolution (LTE) system, uses single auxiliary packet data protocol (PDP) context activation process to activate a plurality of service carriers.In GPRS and LTE system, this process can be implemented with GPRS twin tunnel mode and straight-through tunnel style.
Background technology
Usually, cellular network only designs for voice service.GPRS then supports the data, services of some type, for example communication of text messages and Email.But, more data service and multimedia service are arranged at present as operating in the application on the cellular network and being introduced into, for example by the voice transfer (VoIP) of Internet protocol, Internet protocol (IP) TV (IPTV) or the like.Mobile phone becomes integrated data center apparatus from voice service phone, and cellular network is also just towards next-generation full-IP network and packet service evolution with IP Multimedia System (IMS) architecture.Except the needs for high data rate more, cellular network also is necessary framework is implemented that more effective support IP uses and needed change (just reduce because a plurality of set up delay and because the time delay of crossing the service data traffic carrying capacity that multiprocessing caused on the heterogeneous networks node that process causes) is served in packet switching (PS).
Fig. 1～3 shows is signaling in legacy wireless communication system 100, and wherein this system 100 comprises wireless transmitter/receiver unit (WTRU) 105, radio access network (RAN) 110, service universal grouping wireless electric industry be engaged in (GPRS) support node (SGSN) 115 and Gateway GPRS Support Node (GGSN) 120.Concerning 3GPP PS service, a packet data protocol (PDP) context is associated with a radio access bearer (RAB).Thus, shown in Fig. 1～3,, be necessary to use a main pdp context activation and a plurality of auxiliary pdp context activation to enable these services, and in 3GPP technical specification (TS) 23.060, this be described in order to support a plurality of services.For instance, hope is linked to each other with service (just VoIP, multimedia or the like) based on IMS and activates at one time the data user of services such as Web browsing, E-mail service, fax services, and this data user is necessary for the independent PDP context activation of each service execution.Before all services all moved, the user might wait for considerable time, and this situation is similar with the wait computer guiding.
Current, concerning 3GPP PS service, a PDP Context is associated with a RAB.Thus, as illustrated in fig. 1 and 2, in order to support a plurality of services, be necessary to activate a Your Majesty hereinafter with a plurality of auxiliary PDP Contexts.In addition, in order to support the IMS service, the main PDP Context that is used for session initiation protocol (SIP) signaling all is essential with the auxiliary PDP Context that is used for (to be activated) each data, services all the time.
Summary of the invention
The present invention is that 3GPP system (just GPRS, UMTS) and LTE system provide a kind of method and apparatus, described method and apparatus can reduce since a plurality of service of setting up process continuously and being caused set up postpone and since in the network different nodes cross the data service service processing time delay that multiprocessing caused.The present invention proposes a kind of auxiliary pdp context activation of simplification, this process can activate several services in single step.The present invention also is reused for current 3GPP pdp context activation the distributing IP address, starts service and sets up the tunnel transmission between the different parts (just RAN, SGSN, GGSN, IMS or the like) of network internal.In addition, the present invention allows to use the auxiliary PDP context activation of single step to activate a plurality of PDP Contexts, and wherein each the service all with core network (CN) in some service carrier and the specific RAB among the RAN be associated.In addition, the present invention also allows for different QoS requirements and sets up a plurality of RAB that are mapped to a PDP Context.Described a plurality of PDP Context both can be set up for specific needs (for example bundled services), also can set up when WTRU is connected to a plurality of PDN.
The present invention has reduced the delay of auxiliary PDP context activation, and has reduced the modification that will carry out when the more services of needs.For instance, the user can be configured the PDA(Personal Digital Assistant) terminal, to activate VoIP service, video conference, email account or the like when the PDA terminal is switched on.According to the active procedure among the TS23.060, WTRU will carry out each process separately in order.The present invention has then reduced the unnecessary step of using in activating auxiliary PDP Context process.Whether WTRU can ask additional bearer by sending to RAN (for example e Node B), and described RAN then can check this request, adapt in current PDP Context (carrying just) resource of having distributed to understand additional bearer.In the time can adding additional bearer, the e Node B can be forwarded to this request Mobility Management Entity (MME), further to check.
This requested service type need to determine whether auxiliary PDP Context.If requested service is to be provided by the different PDN that are in different anchor nodes, so auxiliary PDP Context is essential.If requested service is provided by same PDN and anchor node, MME can be forwarded to this service request this anchor node so, to distribute necessary resource and to give new service carrier with network layer SAPI service access point identifier (NSAPI) mapping of WTRU request.Then the be told tunnel endpoint identifier (TEID) of the support e Node B in this processing of this anchor node.Receive reply after, MME determines another end points in tunnel by send the RAB request of setting up to the e Node B, wherein this end points is with the TEID renewal of anchor node.Then, MME will ask WTRU to upgrade its RAB resource.Subsequently, WTRU uses to finish and notifies to make response to the e Node B, and described e Node B then transfers to inform that to MME this processing completes successfully.If go wrong on MME or timer expiry, MME will continue to discharge the tunnel and the resource of previous distribution so.
The reason that the present invention is better than prior art is: 1) in main PDP Context internal distribution several carryings; 2) twin tunnel of handling with respect to 3GPP (GPRS) (new framework) is set up in single tunnel; And 3) step number reduces (will assist PDP to activate with the RAB request of setting up has been incorporated in).

When hereinafter mentioning, term " wireless transmitter/receiver unit (WTRU) " is including, but not limited to the subscriber equipment of subscriber equipment (UE), mobile radio station, fixing or moving user unit, beep-pager, cell phone, PDA(Personal Digital Assistant), computer or any other type that can work in wireless environment.When hereinafter mentioning, term " base station " is including, but not limited to the interface equipment of Node B, site controller, access point (AP) or any other type that can work in wireless environment.
According to an embodiment of the invention, Fig. 4 has shown the process that is used for PDP context activation and RAB distribution in the LTE system 400 that comprises WTRU 405, e Node B 410, MME 415 and anchor node 420.Concerning a plurality of set of services, do not need the auxiliary PDP context activation that adds.The dynamic requests of new service is set up by RB and is provided and release between WTRU 405 and e Node B 410.
With reference to figure 4, in step 422, WTRU 405 sends to MME 415 and activates the PDP Context request message.For instance, the content of this message comprises NSAPI, transaction identifiers (TI), PDP type, pdp address (if having asked static PDP address), APN (APN), QoS, service list or the like.
Should be noted that the implication of QoS request is different from current pdp context activation.Current, QoS only is applicable to this PDP Context.Main PDP Context and auxiliary PDP Context and the RAB that is mapped to them respectively can have different QoS.According to the present invention, QoS be one to all RAB that belong to this PDP Context applicable scope all, and WTRU 405 probably only has a PDP Context that is used for an IP address.Service list is new parameter, and it provides that WTRU 405 expection relies on this PDP Context and the scope of the IP service of setting up with core network (CN).
In step 424, PDP type, pdp address and the APN that MME 415 uses WTRU 405 to provide verifies the PDP Context request that activates.Under the situation that has provided ability and present load, MME 415 can limit requested QoS attribute.This MME 415 can send to affected anchor node 420 and create PDP Context request message (QoS, the TEID of PDP type, pdp address, APN, process negotiation, NSAPI, international Integrated Service Digital Network(ISDN) (ISDN) number of mobile radio station (MSISDN) or the like).In step 428, anchor node 420 will be created the PDP clauses and subclauses for effective PDP Context request.That be associated with requested each service all is different PDP.In this case, if all the service all be by/provide by same gateway (just anchor node 420), will have an IP address and a plurality of port numbers so.Each port numbers all is associated with the service that just is being activated.In addition, in step 428, anchor node 420 also can be created charge information for effective PDP Context request.Each service will be charged separately according to Different Rule.For example, the expense of video call can be different from the expense of text message.Thus, each service all can have different charging ID.Then, anchor node 420 can send to MME 415 and create PDP Context response message (step 430).
In step 432,434,436 and 438, RAB sets up as current and sets up process by RAB distribution/RB and carry out.The QoS that exchanges between RAN (for example the e Node B 510) and CN is used for specific RAB, and this QoS should be in the QoS through negotiation of PDP Context.The sign of the PDP Context that is associated with this RAB will be passed to WTRU 405.If the QoS of RAB demotes from the QoS through consulting of PDP Context, but, therefore at this moment there is no need PDP Context is made amendment so owing to there is being more resources time spent to distribute more RAB/RB for same services.
If successful execution above institute in steps, MME 415 can return to WTRU 405 and activate PDP Context and accept message (PDP type, pdp address, TI, through the QoS that consults, radio priorities or the like) (step 440) so.At this moment will set up the RB that is associated with PDP Context and GPRS tunneled protocol (GTP) tunnel (step 442,444) between anchor node 420 and e Node B 410.
Shown in the process 450 of Fig. 4, for requested each new service at WTRU 405 places, new RB/RAB (step 452) is set up in wherein each service that is necessary for.WTRU 405 sends message to e Node B 410 and comes to be the new RB (step 454) of new service request.The QoS request relevant with service then can be transmitted with this message.E Node B 410 is checked the availability (step 456) of resource, if there are not enough resources, it can refuse this request so.This e Node B 410 can be forwarded to MME 415 with this request, with the RAB (step 458) that will look for novelty.Set up the NSAPI (RAB that in main pdp context activation, sets up just) that handles because WTRU405 knows from a RAB, so MME 415 will understand which PDP Context this request should be associated with.
MME 415 informs to have the new RAB (step 460) that sets up for certain PDP Context to anchor node 420.420 of anchor nodes are the necessary resource of this service assignment at the tunnel end, upgrade and charge and routing iinformation, and to MME back response (step 462).
RAB distribution and RB set up process (step 464,466,468 and 470) and carry out in a conventional manner.These steps 464,466,468 and 470 can with step 460 and 462 executed in parallel, do like this and can reduce to postpone.When having asked new service on step 452, the step of process 450 will repeat.
Fig. 5 has shown another execution mode according to the present invention and the pdp context activation carried out in LTE system 500, wherein this system 500 comprises WTRU 505, e Node B 510, MME 515 and anchor node 520.In the process that is proposed, do not need the auxiliary PDP context activation that adds for many groups of services.Dynamic requests about new service is provided and release between WTRU 505 and e Node B 510 by RB foundation.
With reference to figure 5, WTRU 505 sends to MME 515 and activates PDP Context request message (step 525).In this request, stipulated tabulation about NSAPI, APN, service and corresponding QoS demand.Should be noted that, different with the traditional pdp context activation that only provides a NSAPI and an APN, the process that is proposed will have the tabulation of NSAPI, service and an APN that will be consulted and be established in a pdp context activation.If occur different service requests after a while, will no longer need the pdp context activation that adds so, limited the signal transmission between WTRU 505 and the e Node B 510 thus.
Still with reference to figure 5, in step 530, this activates the PDP Context request MME 530 checkings, selects at least one APN, and this APN is mapped to anchor node 520, and definite GTP TEID and NSAPI tabulation.This WTRU 505 will use APN to tabulate and enumerate the service that all that need activate.Each service all is to use different N SAPI and QoS profile mark.In step 535, MME 515 sends to anchor node 520 and creates the PDP Context request message.In step 540, anchor node 520 can be created the PDP clauses and subclauses for effective PDP Context request.That be associated with each service of being asked all is different PDP.In this case, if all the service all be by/provide by same gateway (just anchor node 520), will have an IP address and a plurality of port numbers so.Each port numbers all is associated with the service that just is being activated.In addition, in step 540, anchor node 520 also can be created charge information for effective PDP Context request.Wherein each service is according to Different Rule charge separately.For example, the expense of video call can be different from the expense of text message.Thus, each service all has different charging ID.
At this moment, on anchor node 520, will finish pdp context activation.Then, anchor node 520 can guarantee that by creating the acknowledgment phase (step 545) that the PDP Context response message comes start-up operation to MME 515 loopbacks, doing like this RAN (for example the e Node B 510) knows that a plurality of tunnels just be activated (step 550) are arranged.MME then can send the information relevant with the quantity of service that just is being activated and the ASAPI that is associated, pdp address, gateway TEID, WTRU ID (interim ID), thus each Business Stream is carried out corresponding route.Then, RAN (for example the e Node B 510) can be each Service Activation RAB, and each stream is mapped to the ID (step 555) that is associated, and sets up tunnel (step 560) (straight-through tunnel or traditional GPRS twin tunnel (RANAP and GTP)) thus.In step 565, MME 515 successfully finishes activation by activating to handle to WTRU 505 announcements.515 tabulations that can send all services that successfully activated of MME.If fail to activate certain service, MME 515 will indicate the reason of this failed service and failure so.In step 570, WTRU 505 and/or RAN (for example the e Node B 510) can come activation physics RB/ channel according to the availability of the data flow that will transmit.
Concerning the more services that need after a while to set up, it only is that RB between WTRU 505 and the e Node B 510 sets up that said process is constrained to.
In the process that activates PDP Context, RAN and CN will consult to be used for the parameter of PDP Context, for example Maximum Bit Rate, assurance bit rate, maximum delay or the like.Then, the QoS profile can be passed to RAN in RAB assigning process immediately.Concerning all RAB/RB that rely on this PDP Context distribution, its QoS demand should be in the QoS restriction of PDP Context.
What Fig. 6 showed is a plurality of PDP Contexts of setting up for a plurality of PDN in wireless communication system 600.This system 600 comprises WTRU 605, e Node B 610, MME 615, anchor node 620 and APN 625A～625E.If new service needs new APN and needs new IAD thus, MME 615 must be in the new tunnel of distribution between e Node B 610 and the new IAD so.WTRU 605 obtains a different IP address from each PDN possibly.Will set up different PDP Contexts thus.Concerning this set up the process of PDP Context, this process was identical with above-described process.
By the PDP Context process that is proposed, a PDP Context is already enough concerning a plurality of services that an IP address that is used for WTRU 605 is had.For instance, if operator wishes to bind some service by auxiliary PDP Context, the processing of setting up auxiliary PDP Context so can be optional.The processing of auxiliary PDP Context is identical with the current processing of carrying out.
A plurality of RAB/RB can be established and be associated with PDP Context.Short of violation bit rate and delay budget, e Node B 610 should be able to be with respect to a plurality of radio bearers that are used for a plurality of information flows so.If the QoS restriction has been violated in the request about additional bearer from the e Node B, e Node B 610 can inform that existing request needs to revise PDP Context and/or activates auxiliary PDP Context to WTRU 605 so.The quantity of the needed parallel flow of PDP Context can define.If WTRU 605 has exhausted admissible service, its request will be rejected so.
Current, between NSAPI, RAB and PDP Context, exist man-to-man relation.In packet domain, exist one-one relationship equally with the RB sign.Concerning the PDP Context process that is proposed changes, wherein be necessary to set up new mapping.The implication of NSAPI still remains unchanged.In WTRU 605, that NSAPI identifies is PDP Service Access Point (SAP).In MME 615 and anchor node 620, what NSAPI represented is and the PDP Context of mobile management (MM) context dependent connection that wherein this MM context indication is the state of WTRU 605.The MM context has the relevant information of all that and the WTRU that works 605 in network, for example QoS, different security information or the like.RAB ID should have the information about unique ID of NSAPI (PDP Context that is associated with RAB just) and RAB simultaneously.Thus, each RAB is mapped to a PDP Context.The method that how to form RAB ID is obtaining implementing.Concerning RB ID, it can be identical with RAB ID.
