Abstract

The invention discloses an idle mode signaling reduction (ISR) activation and deactivation method. The ISR deactivation method includes the following steps: UE receives a deactivation loading request sent by a mobile management unit, wherein the deactivation loading request is used for requesting the UE to reestablish connection; and if the UE already activates the ISR, when it is detected a reason value which is deactivated is a need of connection reactivation and/or service gateway reselection under a condition that the mobile management unit indicates that a network supports non-mobility, the ISR is deactivated. Through the method, a problem that ISR states at a network side and a UE side are different is solved and a limit that TA settings of a local network and other networks are different is demanded is removed so that network resources are saved.

Description

The method of ISR activation and deexcitation

Technical field

The present invention relates to the communications field, activate and the method for deexcitation in particular to a kind of ISR.

Background technology

In order to keep 3-G (Generation Three mobile communication system) in the competitiveness of the communications field, for user provides the Mobile Communication Service that speed is faster, time delay is lower, more personalized, simultaneously, reduce the operation cost of operator, 3GPP(3rd GenerationPartnership Project, third generation partner program) standard operation group is just being devoted to the research of evolved packet system (EvolvedPacket System, be called for short EPS).Fig. 1 is the Organization Chart of the evolution grouping domain system according to correlation technique, and as shown in Figure 1, whole EPS is divided into wireless access network and core net two parts.In the core network, contain home subscriber server (Home Subscriber Server, referred to as HSS), Mobility Management Entity (Mobility Management Entity, referred to as MME), Serving GPRS Support Node (Serving GPRS Support Node, referred to as SGSN), policy charging rule function (Policy and Charging Rule Function, referred to as PCRF), gateway (ServingGateway, referred to as S-GW), packet data gateway (PDN Gateway, referred to as P-GW) and packet data network (Packet Data Network, referred to as PDN).Detailed functions below:

Home subscriber server (HSS), contains all functions of attaching position register (HLR), is the permanent storage place of user contracting data, is positioned at the home network that user contracts.

Mobility Management Entity, be the storage place of user contracting data in current network, be responsible for tracking under UE to the mobile management, user's idle pulley of the safety verification function of the Non-Access Stratum signaling management of network, UE, UE and paging management function and bearer management.

Serving GPRS Support Node (SGSN) is the business support point of GERAN and UTRAN user access core network network, functionally similar with Mobility Management Entity, is responsible for the functions such as the location updating of user, paging management and bearer management.

Gateway is the gateway that core net arrives wireless system, the data buffer storage under responsible UE to the user plane bearer, UE idle pulley of core net, the function of network side initiating business request, Lawful Interception and packet routing and forwarding capability; Gateway is responsible for the situation that counting user UE uses wireless network, and produces the ticket that UE uses wireless network, sends charging gateway to.

Packet data gateway, it is the gateway of evolution system and this its exterior packet data network, it is connected on internet and packet data network, be responsible for the function such as Internet protocol (Internet Protocol, referred to as IP) address assignment, billing function, grouping packet filtering, policy control of UE.

GGSN (Gateway GPRS Support Node; referred to as GGSN); support the edge routing function of GPRS network, namely GGSN is responsible for the data of GPRS network to carry out routing forwarding, and protects the integrality of GPRS network data by fire compartment wall and filtering function.GGSN also has billing function.

PGW contains the repertoire of GGSN, can think and be embedded in the subfunction of GGSN as PGW in PGW.Therefore SGSN can directly be connected with PGW, uses Gn/Gp interface.

Packet data network is the IP operation network of operator, this network by the core net of operator for user provides IP to serve.

Policy charging rule functional entity is the server being responsible for providing charging control, online diameter credit control, thresholding control, service quality (Quality of Service, referred to as QoS) tactful aspect rule in evolution system.

Wireless access network, by evolution base station (E-UTRAN NodeB, be called for short eNB) and 3G radio network controller (RadioNetwork Control, be called for short RNC) composition, the transmitting-receiving of its primary responsibility wireless signal, by air interface and UE contact, the Radio Resource of management air interface, scheduling of resource, access control.

Base station from home (Home NodeB, referred to as HNB) or base station from home (the Home eNodeN of evolution, be called for short HeNB) be small-sized, the lower powered base station of a class, as the dedicated resources of certain user, be deployed in the private sites such as family, group, company or school to use, mainly in order to provide higher service rate to user and reduce the expense used required for high rate services, make up the deficiency that existing distributed cellular radio communication system covers simultaneously.The advantage of base station from home is economical, convenient, low-power output, plug and play, broadband access, use single mode UE etc.

Base station from home can be applied in 3G(3Generation, the third generation) or LTE(Long Term Evolution, Long Term Evolution) in mobile communications network.For the ease of managing base station from home, introduce new network element, i.e. a home base-station gateway in a network.The function that home base-station gateway mainly performs is: the fail safe of checking base station from home, carries out maintenance management to the operation of base station from home, according to Carrier Requirements configuration and control base station from home, is responsible for the data message of exchcange core net and base station from home.

In some specific base station from home and ordinary base station, allow composition local network.When local network deploys local gateway time, allow UE to access local service, access from this locality comprising internet business.Fig. 2 gives the data flow under different local network deployment scenario with Fig. 3.Fig. 2 is the Organization Chart that the local network of correlation technique deploys independent local gateway, as shown in Figure 2, when UE is by this gateway accessing local service, if UE also has core network service simultaneously, can think that local gateway is integrated with the function of original SGW, so the data flow of core net needs by local gateway.If now only have core network service, then the data flow of core net does not need through local gateway, but send to the PGW of core net by the SGW of core net.Fig. 3 is the Organization Chart that the local network of correlation technique does not dispose independent local gateway, and as shown in Figure 3, when UE is by this gateway accessing local service, if UE also has core network service simultaneously, so this data flow does not need through local gateway.

Therefore can find out in fig. 2, start to establish core network service if UE establishes simultaneously, follow-up when will set up local service, may need to reselect a SGW to realize the switching of above-mentioned data flow.

In EPS, in order to reduce the space interface signaling between UE and core net, introduce ISR(Idle mode SignalingReduction) function.After have activated this function, there is the UE of UTRAN/GERAN and E-UTRAN access function simultaneously, MME and SGSN can be registered to simultaneously.Like this, when UE moves under two kinds of different Access Networks, UE can not initiate inter RAT(Radio Access Technology) routing region updating (Routing Area Update, referred to as RAU) or tracking area update (Tracking Area Update, referred to as TAU).Thus decrease unnecessary signaling.Fig. 4 is the schematic flow sheet of the UE activation ISR of correlation technique, as shown in Figure 4, supposes that UE starts by UTRAN/GERAN access network, if first similar from E-UTRAN access network situation, does not repeat here:

Step S400, UE are accessed by UTRAN/GERAN, and complete registration and corresponding bearing activation.

Step S401, UE move to EUTRAN and initiate TAU to MME, wherein carry the information such as effective PTMSI, RAI

The PTMSI that step S402, MME provide according to UE obtains the contextual information of UE to SGSN.

Step S403, SGSN return the contextual information of this UE after completing various verification to UE to MME.If this SGSN supports ISR function, comprise parameter " ISR Capability " in this response and indicate support ISR.

Step S404, MME check whether to be needed to reselect S-GW, if do not need and MME be also support ISR, so this MME thinks that ISR function can activate.In context confirmation response, add ISR instruction, notice SGSN can continue the context safeguarding this UE.

Step S405, MME send bearer update request to S-GW, carry parameter ISR, for notifying that S-GW have activated ISR in request.

Step S406 ~ step S407, if need to upgrade positional information etc., SGW also needs to send bearer update request to PGW, and PGW receives and returns bearer update response to SGW.

Step S408, S-GW arrange ISR and activate mark in this locality, and send bearer update response to MME.

Step S409 ~ S410, MME sends position updating request to HSS.HSS sends location updating response, wherein carries the subscription data of UE.

Step S411, MME send TAU to UE and accept message, wherein comprise ISR and activate instruction, and are the information such as GTUI and TA list of UE distribution.

Step S412, UE return TAU to MME and complete message.

In ISR activation process, require that SGW must be EUTRAN access and UTRAN/GERAN access service simultaneously.If two kinds of access technologies can not use same SGW, then ISR can not activate.And when UE initiates business foundation time, UE is only concerned about whether relevant business can be set up, and the data flow of this business, namely by local gateway access or core network gateway access, the position of the gateway selected by UE when therefore network selectes gateway, can't be notified.But due under Fig. 2 framework, if the gravity treatment of SGW may cause network asynchronous with UE side ISR state under the non-moving state of network support, in prior art, require that local network follows the TA setting of other networks different.This mode can bring certain difficulty for the network planning of operator.Because many times local network is overlapping with the base station of general network on covering.If TA sets difference, then UE can be caused when these overlapping regions are moved to trigger a large amount of TAU flow processs, and the flow process of these TAU can consumption of network resources greatly.

Network and the nonsynchronous problem of UE side ISR state may be caused for the gravity treatment of SGW under the non-moving state of network support in correlation technique, not yet propose effective solution at present.

If SGSN oneself does not support the gateway gravity treatment in non-moving situation, if SGSN judges that the signing permission of UE uses local shunting business, or UE has established the shunting service connection of gateway separation, then SGSN uses two independent IE to inform MME respectively, or now in step S504, do not comprise ISR and support that IE shows not support ISR function.

Local connection for UE can be that two new IE indicate respectively also can be that same IE indicates, if latter satisfies condition fill this IE for the moment.

Whether step S505 ~ S506, MME indicates according to SGSN in step S504 is supported ISR, if SGSN represents do not support ISR, then does not need to carry out about the judgement of ISR in subsequent step.If MME judges to need gravity treatment SGW, then do not need to carry out about the judgement of ISR in subsequent step.If MME and SGSN supports ISR and SGW does not need gravity treatment, then also need to carry out follow-up judgement.If in step S504 MME receive UE support local shunting business and or establish the ability instruction that the instruction of local shunting business and SGSN support the gateway gravity treatment in non-moving situation, MME is according to whether supporting that the SGW gravity treatment in non-moving situation judges whether activation ISR function.If MME supports the SGW gravity treatment in non-moving situation, do not activate ISR function, otherwise MME judges to activate ISR function.If MME finally judges to activate ISR function, then in step S506, add ISR instruction in context confirmation response, notice SGSN can continue the context safeguarding this UE.

If MME finally judges to have activated ISR, then perform the process of similar step S405 to step S412, do not repeat here.This flow process does not activate for ISR and describes residue flow process.

Step S507, MME send bearer update request to S-GW, wherein do not carry ISR and activate.

Step S508 ~ step S509, if need to upgrade positional information etc., SGW also needs to send bearer update request to PGW, and PGW receives and returns bearer update response to SGW.

Step S510 ~ S511, if ISR un-activation, then SGW deletes the resource relevant to ISR, and sends deleting bearing request to registering SGSN before.

Preferably, step S508 does not have clear and definite ordinal relation with step S510.

Step S602 ~ S603, SGSN checks the local connection status of oneself ISR ability and UE.If oneself and corresponding SGW support ISR function, further judge oneself support to the ability of the gateway gravity treatment in non-moving situation, and the local connection of UE.If the signing permission of UE uses local shunting business, or UE has established the shunting service connection of gateway separation, then inform MME in the context when sending forwarding redirect request to MME at UE.If SGSN supports the gateway gravity treatment in non-moving situation, then to MME send forward redirect request time at UE context time inform MME.Above-mentioned concrete notification procedure can be:

If the signing permission of UE uses local shunting business, or UE has established the shunting service connection of gateway separation, then SGSN uses independent IE to inform MME, or now in step S603, does not comprise ISR and support that IE shows not support ISR function.

If SGSN oneself supports the gateway gravity treatment in non-moving situation, then SGSN uses independent IE to inform MME, or now in step S603, does not comprise ISR and support that IE shows not support ISR function.

If SGSN oneself does not support the gateway gravity treatment in non-moving situation, if SGSN judges that the signing permission of UE uses local shunting business, or UE has established the shunting service connection of gateway separation, then SGSN uses two independent IE to inform MME respectively, or now in step S603, do not comprise ISR and support that IE shows not support ISR function.

Step S604 ~ step S605, if MME judges to need gravity treatment SGW, then does not need to carry out about the judgement of ISR in subsequent step.Here suppose that MME judges not need gravity treatment SGW.MME sends handover request to eNB, wherein carries the carrying needing to switch, the information such as Target cell.Carry out resource reservation after eNB receives, complete backward MME and return handoff request acknowledgment message, wherein carry the carrying successfully carrying out resource reservation.

Whether step S606 ~ S607, MME indicates according to SGSN in step S603 is supported ISR, if SGSN represents do not support ISR, then does not need to carry out about the judgement of ISR in subsequent step.If MME and SGSN supports ISR and SGW does not need gravity treatment, then also need to carry out follow-up judgement.If in step S603 MME receive UE support local shunting business and or establish the ability instruction that the instruction of local shunting business and SGSN support the gateway gravity treatment in non-moving situation, MME is according to whether supporting that the SGW gravity treatment in non-moving situation judges whether activation ISR function.If MME supports the SGW gravity treatment in non-moving situation, do not activate ISR function, otherwise MME judges to activate ISR function.If MME finally judges to activate ISR function, then in step S607 repeating relocation response, add ISR activate instruction, notice SGSN can continue the context safeguarding this UE.

Step S608, performs the residue flow process switched, similar with correlation technique.

Step S609, UE initiate TAU flow process, do not need in this process in the judgement performing ISR, but complete in message at TAU, and MME needs notice UE whether to have activated ISR.According to the judgement of step S607, whether notice UE activates ISR.
