It comprises: the source edge radio base-station ERS1 of mobile terminal saves the context of radio access network and the mobile terminal ID of the mobile terminal and monitors the state of mobile terminal when the mobile terminal enters into idle state or sleep state; when ERS1 detects that sleep state and idle state of the mobile terminal reaches a first time threshold, it sends the radio access network context and the mobile terminal ID saved by itself to the access gateway where the ERS1 locates at to save, and deletes the local record and releases radio resources.
Description
Technical field
The present invention relates to mobile communication technology, particularly under the evolution network framework, portable terminal when resting state or idle condition according to the contextual control method of the position transfer of portable terminal.
Background technology
UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) be to adopt WCDMA (Wideband Code Division Multiple Access, the Wideband Code Division Multiple Access (WCDMA) access) 3-G (Generation Three mobile communication system) of air interface technologies also calls the WCDMA communication system to the UMTS system usually.
The UMTS system configuration has adopted and the similar structure of second generation mobile communication system as shown in Figure 1, comprises RAN (Radio Access Network, Radio Access Network) and CN (Core Network, core network).Wherein RAN is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.CN is from being divided into CS (Circuit Switched Domain in logic, circuit commutative field) and PS (Packet SwitchedDomain, packet-switched domain), with UTRAN (UMTS Territorial Radio Access NetworkUMTS, land radio access web), CN and UE (User Equipment, subscriber equipment) constituted whole UMTS system together, the UMTS system connects external network, for example: PSTN and the Internet.
UTRAN is a land radio access web, and network configuration comprises one or several RNS (Radio Network Subsystem, RNS) as shown in Figure 2.A RNS is made up of a RNC (RadioNetwork Controller, radio network controller) and one or more NodeB (base station).Interface between RNC and the CN is the Iu interface, and NodeB is connected by Iub interface with RNC.In UTRAN inside, interconnected by Iur between the RNC, Iur can connect or connect by transmission network by the direct physical between the RNC, and RNC is used for distributing and is attached thereto with control or the Radio Resource of relevant NodeB.NodeB then finishes the conversion of the data flow between Iub interface and the Uu interface, also participates in a part of RRM simultaneously, wherein:
1, NodeB is the base station (being radio receiving-transmitting unit) of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts.By the Iub interface and the RNC interconnection of standard, mainly finish the processing of Uu interface physical layer protocol, major function is spread spectrum, modulation, chnnel coding and despreading, demodulation, channel-decoding, also comprises the functions such as mutual conversion of baseband signal and radiofrequency signal.
2, RNC is a radio network controller, is used to control the Radio Resource of UTRAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.
3, used the Iu series interfaces among the UTRAN, comprised Iu, Iur and Iub interface.
The core network architecture in 3GPS territory as shown in Figure 3, wherein:
1, SGSN (Serving GPRS Support Node, Serving GPRS Support Node) is a basic composition network element of PS network.Its significant feature is exactly the IP grouping of transmitting I/O for the UE of this SGSN coverage, and its status is similar to the VMSC in the CS territory.SGSN provides following function:
The route and the forwarding capability of the packet data package in this SGSN area are for all PS in this SGSN area (Packet Switched, packet switching) user provides service; Encrypt and authentication functions; Conversation management functional; The mobile management function; Interface functions such as same UTRAN, GGSN, HLR, MSC, SMS-GMSC, SMS-IWMSC; Ticket produces and output function, mainly collects the operating position of user to Radio Resource; In addition, also integrated (the Visitor LocationRegister of VLR in the CS network that is similar among the SGSN, Visited Location Registor) function when the user is in Attached (adhering to) state, has been stored among the SGSN with grouping relevant user profile and positional information.Similar with VLR, the most of user profile among the SGSN is obtained from HLR in position updating process.
2, GGSN (Gateway GPRS Support Node, Gateway GPRS Support Node) also is one the Network Element Function entity of introducing in order to provide the PS business function in the UMTS network, and route and the encapsulation of packet between PS net and external data network is provided.Which GGSN the user selects as gateway, is definite according to the Access Point Name (APN) of user's CAMEL-Subscription-Information and user's request in pdp context activation.GGSN mainly provides following function:
With the interface function of external IP packet network, the critical point function that GGSN need provide UE to insert extenal grouped network, from the viewpoint of extranets, GGSN just likes the router of all User IPs in the addressable PS network, need be with the external network exchanging routing information; Session management is finished UE and is set up process with the communication of extranets; Mobile subscriber's grouped data is mail to the function of correct SGSN; The generation of ticket and output function mainly embody the operating position of user to external network; Migration (reorientation, Relocation).
SRNS Relocation is exactly the process that the role of the SRNC of certain UE is forwarded to another one RNC by a RNC, before the SRNS Relocation, the SRNC of this UE (Serving RNC) be SourceRNC, the Target RNC that is about to bear SRNC role is Target RNC, and Source RNC and TargetRNC are for the appellation of different RNCs in SRNS Relocation process.
Lossless migration (lossless Relocation) is meant in migration not obliterated data, is mainly used in AM pattern (affirmation mode), need be between two RNC transferring data and PDCP sequence number etc.
At present in 3GPP, each active research LTE of manufacturer (Long Term Evolution), the purpose of LTE provides a kind ofly can reduce time delay, improve the network cheaply of user data rate, improved power system capacity and covering.Only use PS territory business, bearer network all is the IP carrying.Wherein: a kind of popular be the two-layer node framework as shown in Figure 4, under this framework, ERS (Edge Radio Station, the wireless base station, edge) is the Node B of evolution, the function of most RNC before having, and take new physical-layer techniques, IAGW (IP Access Gate Way, IP IAD) to have the function of part SGSN and the function of former GGSN.Interface between IAGW and the ERS is the E-I interface, and it is the IP link that evolution architecture generally requires it.
In evolvement network, in the function separate table of RAN/CN, Location management, Paging, Intra-radio access mobility in LTE_IDLE is an important project.Present trend is that UE has Detached (separating, i.e. off-mode), IDLE (free time, i.e. holding state), Active (active state) and Dormant (dormancy, i.e. power down mode) state.
Wherein, the Detached state is a released state, the information such as mobility that UE is not preserved in CN and RAN inside.The IDLE state class has only CN to preserve the mobility context (MMContext) of UE like existing IDLE state, and UE relevant information (yet having manufacturer to propose and will preserve information at RAN) is not generally preserved in RAN inside.The Active state is the UE normal communication state, connects with network, and RAN and CN have the information of UE, and RAN preserves the RAN context of the UE relevant with radio communication, and CN preserves mobile management context (MM Context) and the PDP Context of UE; The Dormant state is the resting state of UE, and under this state, session does not discharge, but the UE activity is not strong, is in battery saving mode.When business continues, quick-recovery business soon.The DORMANT state class is like the URA_PCH state of UMTS network, wish to preserve the RAN Context of UE, CN preserves MM Context and the PDP Context of UE, the quick-recovery business when UE is in Idle state and Dormant state, changes according to the UE affiliated subdistrict so soon, the RAN side need shift RAN Context, according to the variation in route district under the UE, need MM Context and/or the PDP Context of UE be shifted, can recommunicate as early as possible to make things convenient for UE.
Concerning the evolvement network (or protocol stack is in other networks of bottom layer node) of two-layer node, the UE of Idle state and Dormant state moving between ERS causes the frequent transfer of the RAN Context of UE.And UE may not often recover professional.Because the silence period of a lot of UE is longer, may strides a plurality of ERS and just initiate business, even no longer initiate professional.Under this condition, frequent transfer Context affects to network.

Embodiment
For the UE that reduces Idle state or Dormant state moves the transition frequency of the corresponding Context that causes, the present invention proposes two kinds of solutions, makes the transfer of carrying out the Context of UE when UE needs again, with conserve system resources.
Method 1
When UE transfers the Dormant state to by Active, the RAN context of UE is kept at RAN corresponding node (as ERS) earlier, mobile management context (MM Context) block data protocol context (PDPContext) is kept at corresponding IAGW, shift as required then, guarantee when UE may recover business subsequently, can change over to fast the Active state like this and communicate.UE is provided with identical timer RAN timer1, CN timer2 with network.When UE changed the Dormant state over to, timer timer1 picked up counting at UE and RAN.When timer timer1 arrival set point, RAN Context passes to CN (as IAGW) and preserves, and the interface between RAN and the CN and user's face discharge simultaneously.
If UE moved to other ERS scopes before timer timer1 was overtime, shift RN Context by following two kinds of methods:
1, UE initiates cell update, and RAN Context transfers to new ERS (transfer to, mean original C ontext deletion), and timer1 continues timing; Renewal process may upgrade specifically comprising the steps: more than once each time
1) portable terminal is initiated cell update;
2) ERS before upgrading continues the ERS that the RAN context of this portable terminal sends to after the described renewal to preserve, and deletes local record then and discharges E-I interface and Radio Resource;
3) ERS after the described renewal sets up Radio Resource according to described RAN context, and when continuing to monitor described very first time threshold value and arriving, described RAN context and mobile terminal identification are sent to described IAGW1 continuation preservation, delete local record then and discharge E-I interface and Radio Resource.
Perhaps, can also be by upgrading the ERS request of back ERS of living in before described renewal with this portable terminal RAN context.
2, UE initiates renewal process, new ERS notification source ERS, and source ERS passes to CN with RAN Context and preserves, and discharges E-I and connects, and similar timer1 is overtime, and timer1 resets simultaneously; Renewal process may upgrade specifically comprising the steps: more than once each time
1) described portable terminal is initiated cell update;
2) ERS after the renewal notifies the preceding ERS of described renewal that the RAN context of this portable terminal is sent to described IAGW1 preservation;
3) after the ERS before the renewal receives described notice, the RAN context that sends this portable terminal is sent to described IAGW1 continue to preserve, delete local record then and discharge E-I interface and Radio Resource.
After RAN Context passes to CN, the similar IDLE state of the behavior of UE, in UE moves, when changing ERS, can the triggering cell renewal etc. process, only change, just trigger Routing Area Update process (Routeing Area Update) (also can in this process CN download RAN Context), and upgrade the middle route regional address information of MM Context (MM Context) to current RAN node in the route district.When UE changes the CN node, then other relevant informations such as RAN Context and MM Context and PDP Context are together transferred to new CN node, and carry out PDP Context and upgrade (Update PDP Context), upgrade wherein IAGW address information, notify the address of the new IAGW in critical point IAGW (Gateway IAGW, similar GIAGW, professional exit point) UE location simultaneously, if downlink data is arranged like this, critical point IAGW can find the IAGW at UE place with distributing paging.
Professional when the UE recovery, then CN downloads RAN Context to the current place of UE RAN node, to recover communication.Otherwise, if UE is unmovable always, timer timer2 expires, and (timer2 can transfer Dormant to from UE and pick up counting, or timer1 timing when finishing, specific implementation is relevant), then delete the RAN Context in the CN, putting the UE state is the Idle state, and the session (session) of putting all PDP of UE is expired, initiates deletion PDP Context process (Delete PDP Context).
When UE is in Dormant, network side has data to give UE, and then CN initiates paging, carries out paging to RA (RouteingArea) district.Simultaneously RAN Context is handed down to RAN node in all RA (as using multicasting technology, the RAN node is received the back if do not have then deletion of UE response at certain hour, to guarantee resource); Again RAN Context is handed down to corresponding RAN node (UE initiates professional below similar) after perhaps waiting the UE response.
When the UE that is in the Dormant state will continue to initiate professional, then UE is by uplink common channel (as RACH), it is in informing network the Dormant state and informs its sign, RAN node (as ERS) utilizes the RAN Context of sign to CN request UE correspondence, CN is handed down to this RAN Context the RAN node and sets up the E-I link, the RAN node uses this RAN Context to rebuild the Radio interface protocols stack, and carries out proper communication with UE.(it is that similar flow chart 4 removes the paging that network issues that UE initiates professional flow process)
When UE and network carried out proper communication, UE changed the Active state over to, and timer1 and timer2 reset.
By this method, make UE under the Dormant state, only RAN just obtains RAN Context when business rebulids.Otherwise the activity of UE is similar to IDLE state (after RAN Context transfers to CN).When UE had just changed the Dormant state over to or do not moved out the ERS scope, the probability that UE initiates business again was bigger, kept RAN Context at RAN, was convenient to initiate fast professional.
Above timer1 and timer2 that specific implementation is set is relevant, be top method 2 when moving out ERS for infinity as timer1, promptly UE does not move out the ERS scope and then can not shift RAN Context to CN.Timer1 is the top then similar existing realization of method 1 for infinity moves out ERS, and promptly UE moves to the transfer that new ERS then carries out RAN Context.
When the described idle condition of network side paging or resting state portable terminal or when described idle condition or resting state portable terminal sent data, network side was searched described portable terminal present located IAGW and data or beep-page message are sent to this IAGW; IAGW judges whether the E-I interface of this portable terminal correspondence is released, if otherwise by these E-I interface issuing page message or data; If then rebuild the E-I interface of this portable terminal correspondence and issue the beep-page message that carries this mobile terminal identification according to the described route regional address information in the described MM context of this portable terminal to all ERS that are positioned at corresponding route district, and the described RAN context that will preserve is handed down to all ERS of ownership; All ERS in the described route district send the beep-page message that carries this mobile terminal identification simultaneously; During described beep-page message that described portable terminal receives that sub-district ERS of living in sends, send Radio Resource to the ERS of sub-district of living in and rebuild request; Rebuild the Radio Resource of this portable terminal according to the information in the described RAN context when ERS of sub-district of living in receives described reconstruction request and return to this portable terminal and rebuild successful response message, other ERS in the described route district abandon described RAN context when setting-up time arrives; E-I interface issuing page message or the data of described IAGW by rebuilding, described portable terminal receives described beep-page message or data by the Radio Resource of rebuilding.
Perhaps, when the described idle condition of network side paging or resting state portable terminal or when described idle condition or resting state portable terminal sent data, network side was searched described portable terminal present located IAGW and data or beep-page message are sent to this IAGW; Whether the E-I interface that this portable terminal of described IAGW is answered is released, if otherwise by these E-I interface distributing paging or data; If then rebuild the E-I interface of this portable terminal correspondence and issue the beep-page message that carries this mobile terminal identification to all ERS that are positioned at this route district according to the described route regional address information in the described MM context of this portable terminal; All ERS in this route district send the beep-page message that carries this mobile terminal identification simultaneously; During described beep-page message that described portable terminal receives that sub-district ERS of living in sends, send Radio Resource to the ERS of sub-district of living in and rebuild request; When receiving described reconstruction request, the ERS of described portable terminal sub-district of living in asks the RAN context of this portable terminal to described IAGW; Described IAGW sends corresponding RAN context to the ERS of this portable terminal sub-district of living in; The ERS of portable terminal sub-district of living in rebuilds Radio Resource and returns the successful response message of reconstruction to this portable terminal according to described RAN context; Described portable terminal is communicated by letter with E-I interface and network side foundation by the Radio Resource of rebuilding and is received described data or beep-page message.
When described idle condition portable terminal or described resting state portable terminal when network side sends data or signaling, portable terminal sends the Radio Resource that carries mobile terminal identification to the ERS of sub-district of living in and rebuilds request; Portable terminal sends the RAN context request of carrying mobile terminal identification to the ERS of sub-district of living in to the IAGW in route of living in district; The described IAGW of IAGW in route of living in district sends corresponding RAN context and sets up the E-I interface of this portable terminal to the ERS of this portable terminal sub-district of living in; The ERS of portable terminal sub-district of living in rebuilds Radio Resource and returns the successful response message of reconstruction to this portable terminal according to described RAN context; Described portable terminal is communicated by letter with E-I interface and network side foundation by the Radio Resource of rebuilding and is sent described data or signaling.
Be elaborated with embodiment one below:
As shown in Figure 5, under the method 1 (Context is kept at CN), to have data to arrive the idiographic flow of UE as follows when network:
S101, arrive when network has data, by searching the IAGW that HLR understands the current place of UE, then data or beep-page message are sent to the current IAGW of UE, the IAGW distributing paging is to all interior ERS of the RA at UE place;
After S102, ERS receive the paging of CN, continue issuing page message;
After S103, UE received paging, the awareness network side was preserved the RAN Context of oneself, then sent RRC and rebuild request, the sign of carrying similar U-RNTI in the message;
S104, ERS receive that back transmission RAN Context request message request IAGW is handed down to this node with the RAN Context of this UE;
S105, IAGW utilize wherein to identify and find corresponding RAN Context, and by RAN Contextresponse message this Context are handed down to ERS;
ERS sends RRC and rebuilds response to UE, and RAN Context has set up success in the expression RAN, and UE sends direct-sending message paging response untill further notice CN and receives paging afterwards.Carry out proper communication then.The back flow process slightly.
When described idle condition portable terminal or described resting state portable terminal when network side sends data or signaling, portable terminal sends the Radio Resource that carries mobile terminal identification to the ERS of sub-district of living in and rebuilds request; Portable terminal sends the RNA context request of carrying mobile terminal identification to the ERS of sub-district of living in to the IAGW in route of living in district; The described IAGW of IAGW in route of living in district sends corresponding RAN context to the ERS of this portable terminal sub-district of living in; The ERS of portable terminal sub-district of living in rebuilds Radio Resource and returns the successful response message of reconstruction to this portable terminal according to described RAN context; Described portable terminal is communicated by letter with network side foundation by the Radio Resource of rebuilding and is sent described data or signaling.
Method 2
When UE transfers the Dormant state to, other similar approach 1, but the context of UE is kept at the RAN node when UE transferred the Dormant state at that time always rather than uploads to CN, the RAN sign (as U-RNTI, it comprises the RAN node identification) that the UE record distributes.Can timer be set so that discharge the E-I interface behind the certain hour in order to avoid the waste resource.
If UE moved to other ERS scopes before timer timer1 was overtime, following two kinds of processing methods are arranged:
1, UE initiates cell update, and RAN Context transfers to new ERS (transfer to, mean original C ontext deletion), and timer1 continues timing; Renewal process may upgrade specifically comprising the steps: more than once each time
1) the RAN sign of the ERS after portable terminal is initiated cell update and preserved renewal;
2) ERS before upgrading continues the ERS that the RAN context of this portable terminal sends to after the described renewal to preserve, and deletes local record then and discharges E-I interface and Radio Resource;
3) ERS after the described renewal sets up Radio Resource according to described RAN context, and when continuing to monitor described very first time threshold value and arriving, discharges E-I interface and Radio Resource.
2, portable terminal is initiated cell update; Notify the ERS before the described renewal directly to discharge E-I interface and Radio Resource by upgrading back ERS of living in.
After UE moved out this RAN range of nodes, similar Idle state only changed in the route district, just triggers Routing Area Update process (Routeing Area Update).When UE changes the CN node, other relevant informations such as MM Context (MM Context) and PDP Context are transferred to new CN node, and carry out PDP Context and upgrade (Update PDP Context), with notice critical point IAGW (GatewayIAGW, similar GIAGW, professional exit point) address of the new IAGW in UE location, if downlink data is arranged like this, critical point IAGW can find the IAGW at UE place with distributing paging.
When the UE that is in the Dormant state will initiate business, then initiate cell updating course (CellUpdat), trigger forward transition, RAN node is before transferred to new RAN node with RAN Context, carries out proper communication afterwards.
Arrive UE when network has data, CN is in route district (RA) paging, and UE receives back initiation cell updating course (Cell Updat), triggers forward transition, and RAN node is before transferred to new RAN node with RAN Context, carries out proper communication afterwards.
Timer timer3 is set,, then discharges the Context of RAN intranodal when UE is transferring Dormant un-activation business in a period of time to.
This method is transferred to CN with RAN Context, the process of UE when initiating business or receiving paging that is in the Dormant state is different with the UE correlated process of Idle state, UE will send it to network and be in Dormant state information and correlated identities, rather than initiate RRC Connection Setup process and rebuild context, RAN utilizes this sign to ask RAN Context to rebuild context and communication protocol stack to CN, to communicate fast, specifically comprise:
When the described idle condition of network side paging or resting state portable terminal or when described idle condition or resting state portable terminal sent data, network side was searched described portable terminal present located IAGW and data or beep-page message are sent to this IAGW; Described IAGW judges whether the E-I interface of this portable terminal discharges, if otherwise, otherwise rebuild the E-I interface of this portable terminal correspondence and issue the beep-page message that carries this mobile terminal identification to all ERS that are positioned at corresponding route district according to the described route regional address information in the described MM context of this portable terminal by these E-I interface distributing paging or data; All ERS in the described route district send the beep-page message that carries this mobile terminal identification simultaneously; When described portable terminal receives the described beep-page message of current transmission, send the cell update request to current sub-district ERS of living in; The ERS of the current sub-district of living in of portable terminal sends up signaling message transfer to the contextual described ERS1 of RAN that preserves UE, ERS1 trigger carry out forward transition and with the RAN context transfer of this portable terminal to current sub-district ERS of living in; The ERS of current sub-district of living in sets up Radio Resource and returns the successful response message of reconstruction to this portable terminal according to the information in the described RAN context; Described portable terminal is communicated by letter with E-I interface and network side foundation by the Radio Resource of rebuilding and is sent described data or signaling.
When idle condition or resting state portable terminal when network side sends data or signaling, described portable terminal sends the cell update request to described current sub-district ERS of living in; The ERS of described ERS1 and the current sub-district of living in of portable terminal carry out that forward direction upgrades and with the RAN context transfer of this portable terminal to current sub-district ERS of living in; The ERS of current sub-district of living in sets up Radio Resource and returns the successful response message of reconstruction to this portable terminal according to the information in the described RAN context; Described portable terminal sends data or signaling by the Radio Resource of rebuilding.
When the described idle condition of network side paging or resting state portable terminal or when described idle condition or resting state portable terminal sent data, portable terminal sent the cell update request that current ERS sign in sub-district of living in is carried in the sub-district to described ERS1; The ERS of described ERS1 and the current sub-district of living in of portable terminal carries out forward transition and the RAN context transfer of this portable terminal is arrived the ERS of current sub-district of living in; The ERS of current sub-district of living in rebuilds the E-I interface of this portable terminal correspondence and sets up Radio Resource and return the successful response message of reconstruction to this portable terminal according to the information in the described RAN context; Described portable terminal is communicated by letter with E-I interface and network side foundation by the Radio Resource of rebuilding and is sent described data or signaling.
Describe in detail with embodiment two below:
As shown in Figure 6, ERS1 is the current place ERS of UE, and ERS2 is the ERS of the RAN Context of preservation UE, and the call flow idiographic flow when the RAN node is preserved RAN Context is:
S201, when network is arrived by data or beep-page message, IAGW ERS in all RA sends paging;
After ERS under the current RA of S202, UE receives beep-page message, continue to issue down;
S203, UE send cell update message after receiving paging;
S204, ERS1 receive the cell update message of UE, send up signaling message transfer to ERS2 by the U-RNTI sign;
S205, ERS2 receive this message, move flow process, send RELOCATION REQUIRED message to CN.
Carry out normal transition process afterwards, after transition process finished, the RAN Context of UE transferred to ERS1, and CN receives paging by the direct-sending message report, carries out normal communication process.
RAN node when the RAN Context of UE is retained in UE and transfers Dormant in this method, when needs communicated, UE initiated Cell Update process, triggers the forward transition process, forwards RANContext to current RAN node and communicates.This method has been utilized prior art, the convenient realization.The UE that is in the Dormant state initiates business and can comprise signaling procedures such as RA Update, and Context just can in time shift when carrying out signaling procedure like this, shortens signaling procedure and sets up call duration time.If do not comprise this process, the relevant RAN Context of mechanism notice RAN deletion is arranged preferably after the UE deexcitation.
Above two methods, initiate the professional up behavior that comprises any UE if be in the UE of Dormant state, as signaling procedures such as RA Update or Detach, then the RAN Context of UE transfers to RAN earlier, utilize this RAN Context to set up communication then, UE carries out signaling procedures such as RA Update, can shorten process time.This signaling procedure is thought the Active state, and timer1 resets, but the timer2 time-out, when the signaling procedure end, UE changes the Dormant state again over to, and timer2 continues timing, timer1 reclocking.Overtime or UE enters other ERS (reference method 1 correlated process) as timer1, and RAN Context is transferred to CN (method 1) or remains on this RAN node (method 2), the U-RNTI that the UE record is new.
Do not comprise signaling procedures such as RA Update if be in the UE initiation business of Dormant state, only relate to user's face business procedure, then work as UE initiation detach process or CN and carry out implicit detach etc., CN preferably can notify the RAN Context of RAN knot removal UE.(if do not notify and to delete by timer3 is expired)
Method above using, only there is the notion of two lane place in evolvement network, i.e. Cell and RA, Cell is the lane place notion of RAN, does not move out ERS or Timer1 when not yet due at Active state and UE, UE can reach in Cell.RA is the lane place notion of CN, and under Idle or other Dormant states, UE can reach at RA.Simplify the lane place, avoided the repetition and the complexity of lane place.
The present invention supports LTE IDLE state equally, and promptly LTE IDLE state can use thought provided by the invention, and network keeps the Context of UE when UE carries out Attach.When UE moved, Idle state among the similar existing UMTS, UE only carried out operations such as Routing Area Update and periodic location registration.Carry out Context and shift when UE continues communication (as Routeing Area Update or initiation data service), it is less to make that UE sets up communication delay.
The present invention also is not limited to the two-layer node of IAGW, ERS.It is slightly different with top embodiment flow process that three node layers or ERS are divided into user entity, chain of command entity etc., but essential idea is still under inventive concept.
As shown in Figure 4, the method above using, only there is the notion of two lane place in evolvement network, i.e. sub-district Cell and route district RA, Cell is the lane place notion of RAN, does not move out ERS or Timer1 when not yet due at Active state and UE, UE can reach in Cell.RA is the lane place notion of CN, and under Idle or other Dormant states, UE can reach at RA.
The above only is process of the present invention and method embodiment, in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is not equal to replacement, improvement etc., all should be included within protection scope of the present invention.
