Technical field

The invention belongs to moving communicating field, be specifically related to a kind of method of supporting that the terminal in communication system position of disposing Femto base station is upgraded.

Background technology

Base station in WiMAX network can be divided into according to coverage multiple, macro station (Macro BS), micro-station (Pico), Home eNodeB (Femto).Femto is mainly used in family or office, and Femto can be divided into two types, and one is private type, i.e. the Femto of this type (referred to as CSG type Femto) can only provide service for specific terminal; Another type is publicly-owned type, and the Femto of this type (referred to as OSG type) is the same with macro station, can provide service for all validated users; In addition also has a kind of base station of mixed characteristic, this Femto allows particular terminal access, also allow other unspecific terminal access, but the priority that particular terminal accesses and obtains serving is higher than non-user-specific, in the time analyzing, according to different situations, the base station of this type can belong to CSG and OSG type Femto analyzes respectively; For example, in the time judging whether to allow user to access, hybrid base station is analyzed as OSG; In the time doing the relevant control of QoS, should consider CSG characteristic, also to consider OSG characteristic.From terminal use's angle, the private type Femto in network also can be divided into two kinds, and a kind of is the Femto that allows the private type of this terminal access, and another is the Femto that does not allow the private type of this terminal access.

For each CSG Femto, there is a terminal user identification list that allows access, i.e. CSG User List (or CSG Member List); This list can further show that this CSG Femto is controlled or has by which or which terminal use; If some terminal use is casual user, can also indicate the temporal information of this ephemeral terminations user's access.Terminal user identification can adopt terminal use's network access Identifier NAI, terminal MAC Address, and terminal use is the unique index within the scope of this CSG Femto at least.

In addition, CSG Femto can also divide into groups, and group character adopts CSG ID; The CSG Femto with identical CSG ID shares identical CSG User List; Like this, for each terminal use, allow the CSG Femto of access both can adopt CSGFemto List to represent, also adopted CSG ID List to represent; Because terminal use is interim member in some CSG Femto or CSG ID, therefore to these CSG Femto or CSGID, need in CSG Femto List or CSG ID List, indicate the temporal information that allows access.In addition, because terminal use may control or have some CSG Femto or CSG ID (i.e. all CSG Femto corresponding to this CSG ID), therefore also need in CSGFemto List or CSG ID List, show which CSG Femto or CSG ID for this terminal use's control or have.

In addition, in CSG management process, Femto AAA safeguards the terminal user identification list of the permission access of all CSG Femto that Femto-NSP administers, and Femto AAA is according to these lists, can generate based on terminal user identification, allow the CSGFemto List of its access.

So-called Idle state, in the time that terminal and network do not have service interaction, for power saving, enters idle condition from current active state exactly; Terminal enters after idle condition, no longer keep in communication with serving BS, but entering some necessary informations of idle condition can be kept at a logic entity in network, in anchoring paging controller, for example paging group when terminal access idle mode, enters the Base Station Identification of idle pulley; In the time that subsequent network needs call terminal, this terminal of information area paging that will preserve according to anchoring paging controller.

Terminal under idle pulley can be selected a preferred base station, synchronous preferably base station receiving system broadcast; Meet certain condition under idle pulley time, terminal can preferably carried out position renewal under base station, and it is the positional information that network side need to be known terminal of idle mode that position is upgraded on the one hand, is in addition to guarantee that terminal can also keep in communication with network; Position upgrade trigger condition have: terminal present position paging group changes, timer then, shutdown, multicast and broadcast region changes, MAC Hash saltus step count value exceedes MAC Hash saltus step threshold value etc.

When disposing in network behind Femto base station, can bring impact to flow processs such as current paging, position renewal, idle pulley exit.For example, when be deployed with after Femto in network simultaneously, in residential quarters, there is thousands of Femto, in the paging group of, Femto base station number is very huge so, if according to original paging method, can send paging notice message to the surprising Femto of quantity, then allow these Femto send broadcast paging messages call terminal by air interface, thereby cause network burden to strengthen, waste a large amount of air interface resource simultaneously; But in fact a lot of CSG Femto base stations or CSG Femto corresponding to CSG ID do not allow described call terminal access.

When disposing in WiMAX network behind Femto base station, preferential base station when not all Femto base station can be upgraded as terminal position.Upgrade if current preferred base station does not allow terminal to do position, network side also needs some information of notification terminal so that terminal is carried out correct subsequent treatment.Therefore, need to make some amendments to existing position updating process; To can carry out the paging flow process of follow-up optimization, idle pulley enters flow process, and idle pulley exits flow process etc., to alleviate network burden, realizes high efficiency paging.

----each Femto is being deployed to after network, Femto base station self also can obtain and preserve its neighbor base station information, these information comprise base station type, be Femo base station or Macro base station, if Femto base station information also may include Femto base station type, i.e. CSG or OSG type or mixed type; If CSG base station can also be preserved this CSG Femto and be allowed access user list CSG User List, if certain member is interim member, can also comprise the temporal information of this user as CSG member;

---in the database of-H-AAA, there is a terminal use for each, have CSG Femto station list or a CSG ID list that allows this terminal use's access, i.e. CSGFemto List or CSG ID List; In addition user's CSG Femto List can also preserve the user type of this user at CSG Femto, is the characteristics such as Home User, or Non HomeUser, and the access priority of this user on CSG Femto;

----each CSG Femto preserves the terminal iidentification list that allows access, i.e. CSGUser List (or being called CSG Mermber List) is each user ID that allows to access terminal in table; And permission access user access priority; Terminal user identification can be various ways, for example terminal use's network access Identifier NAI, the MAC Address of terminal, or at least unique index in this CSG Femto of terminal use;

----when there being new Femto to be deployed to or to remove after network, can relate to relevant macro station upgrade himself coverage of preserving or and adjacent area in Femto information, and relate to relevant Femto base station and upgrade its adjacent area of preservation Femto base station information;

----it allows after information of terminal user of access when certain CSG Femto renewal (comprise and add or remove), upgrade its CSG User List, in H-AAA database, the CSG Femto List of its access of permission of counterpart terminal user or CSG ID List can be upgraded in time;

----in user CSG Femto List, if user is Home User in the CSG of this Femto UserList, shows that this CSG Femto is all for this user, and this CSGFemto is this user's Home CSG Femto; If user is Non Home User in the CSGUser of this Femto List, show that this CSG Femto is for this user is not all, the Non Home CSG Femto that this CSG Femto is this user.

----in user CSG ID List, if be Home User in the CSG UserList of user in this CSG ID, show this CSG ID (i.e. all CSG Femto corresponding to this CSG ID) for this user all, the Home CSG ID that this CSG ID is this user; If be Non Home User in the CSG User List of user in this CSG ID, show that this CSG ID (i.e. all CSG Femto corresponding to this CSG ID) is not all for this user, this CSGID is this user's Non Home CSG ID.

2. the division of paging group

With regard to the characteristic of Femto base station, its application is mainly that private base station is main, and the Femto of publicly-owned type is mainly deployed in public place; And to each particular terminal, allow the private base station of its access extremely limited, be exactly generally family and office.In this context, can utilize that existing network is technical to carry out less optimization and just can support high efficiencyly to carry out paging to disposing the network of Femto completely.

Existing macro station and paging group thereof are divided without any changes, and the paging group that macro station is divided according to geographical position remains unchanged, and when after Femto base station deployment, decides the paging group of its ownership according to the geographical position at its place; In paging, make full use of terminal and allow the privately owned Femto list information of access to be optimized paging.Detailed process is with reference to the content of following Section 6.

3. configuration information and transmission thereof

Here the configuration information relevant to paging has two classes, and one is CSG Femto List corresponding to each terminal or CSG ID List, and the CSG User List preserving on each CSG Femto or CSG ID.The transmission of the configuration information of speaking of here only relates to the transmission of CSGFemto List or CSG ID List.

Each terminal has a corresponding CSG Femto List, and this List allows the privately owned Femto list of this user access with this preservation, and this list is kept in the network element of core net (for example,, in AAA); Each CSG Femto has a corresponding CSG User List, this list is used for preserving this CSG Femto and allows the user list that accesses terminal, and it is upper that this list can be preserved privately owned Femto, in the AGW of management Femto, and network element (for example,, in AAA) in core net.User list in the CSG User List of CSG Femto can be changed by the owner of Femto, may add or delete user, this amendment can have influence on CSG Femto List or the CSG ID List of associated terminal, the user who adds adds this Femto or CSG id information in its CSGFemto List or CSG ID List, and the user of deletion deletes this Femto or CSG id information in its CSG Femto List or CSG ID List.

Here mainly list and paging related CSG Femto List or CSG ID List transmittance process.

When 3.1 user-network access

After terminal entering network, the network element that its CSG Femto List or CSG ID List, switchover policy can be delivered to Access Network from core net (for example, transmit and be saved in the network element Anchor SFA/Anchor Authenticator of Access Network and continue in Access Network from the H-AAA of core net and transmit and be saved in serving BS from Anchor SFA/Anchor Authenticator, serving BS can be the serving BS of any type here).

3.2 when switch

In the time initiating to switch, no matter be the switching of terminal triggering or the switching that network side triggers, no matter serving BS is macro station or Femto base station, no matter target BS is macro station or Femto base station, and serving BS is in the handover request message that sends to target BS or in switch acknowledgment message, bring this user's CSG Femto List or CSG ID List, the switchover policy information relevant to Femto.

When 3.3 terminal access idle mode

When after terminal access idle mode (IDLE Mode), CSG Femto List or CSGID List, switchover policy are delivered to Anchor PC (anchoring paging controller) as a part of MS Context and preserve.

When 3.4Anchor PC redistributes

In the time of idle pulley, if when Anchor PC redistributes, CSG FemtoList or CSG ID List, the switchover policy information relevant to Femto also can be transferred to New Anchor PC from Old AnchorPC; Interacting message while namely redistributing according to Anchor PC, transfers to New Anchor PC by CSG Femto List or CSG ID List, the switchover policy relevant to Femto from Old Anchor PC.

When 3.5Anchor Authenticators redistributes

If the network element Anchor Authenticators of Access Network preserves the CSGFemto List of terminal or CSG ID List, the switchover policy information relevant to Femto, in the time that AnchorAuthenticator redistributes, CSG Femto List or CSG ID List, switchover policy etc. also can be transferred to New AnchorAuthenticator from Old Anchor Authenticator.Interacting message while namely redistributing according to Anchor Auchenticator, transfers to New Anchor Auchenticator by CSG Femto List or CSG ID List, switchover policy from Old AnchorAuchenticator.

4. position is upgraded

If when updating of terminal position, its serving BS is macro station or OSG Femto or the CSG Femto that allows this terminal access, its position update flow is the same with the position update flow of existing NWG so, just its serving BS type becomes more eurypalynous base station (macro station from macro station, or OSG Femto, or CSG Femto, or the Femto of mixed type).Serving BS (macro station, or OSG Femto, or the CSG Femto) mark that occurrence positions can be upgraded when position is upgraded, passes to Anchor PC and preserves.If the base station that occurrence positions upgrades is CSG Femto, but this CSG Femto does not allow this terminal access, and this CSG Femto can be redirected terminal to the enterprising line position renewal in base station of this CSG Femto vicinity or carry out network reentry.

Different network elements can judge whether to allow current terminal to carry out position renewal in current preferred base station, the information difference of utilizing when different network elements judges; If preferably base station judgement, preferably base station is according to himself allowing the terminal user identification list CSG MemberList of access and terminal user identification to carry out, and anchoring paging controller and anchoring authentication device are to allow the CSGFemto List of its access CSG ID that carry out or that utilize current preferred base station and terminal to allow the CSG ID List of its access to carry out according to the type of current preferred base station, mark and terminal.

Terminal user identification in terminal user identification list can be NAI or MAC Address, or the unique index in this CSG Femto at least.

Recommend new base station also to cry to terminal and be redirected, redirected target BS is according to the neighbor cell configuration of current preferred base station and redirected strategy decision.

If network design or support Femto, each Femto is being deployed to after network, Femto base station self also can obtain and preserve its neighbor base station information, these information comprise base station type, be Femo base station or Macro base station, if Femto base station information also may include Femto base station type, i.e. CSG, OSG, mixed type; If CSG base station can also be preserved this CSG Femto and be allowed access user list CSGMember List; Can select redirected target BS in conjunction with some strategies according to these information.

While being redirected, target BS is selected to be determined by Different Strategies: this CSG Femto might not know the signal strength signal intensity of adjacent area Femto base station around in real time, also not necessarily know whether CSG Femto allows this terminal access around, select macro base station so general while being redirected, because the coverage of macro base station is large and allow all terminals to access; Need to select Femto base station if be redirected, so also will select the Femto base station of OSG type, whether allow this terminal access because this CSG Femto also not necessarily knows CSG Femto around; If need to select Femto base station while being redirected, and know in CSG Femto around which allows the access of this terminal, also can select to allow the CSG Femto base station of this terminal access while being redirected so.

While being redirected, this CSG Femto sends to and in the ranging response message of terminal, should be with following information one of at least: position is upgraded unsuccessfully, the prefix index of redirected target BS; Terminal can be upgraded according to the prefix index of target BS launch position on target BS.

If this CSG Femto does not have configuring adjacent cell information, when CSG Femto does not allow after this user's access according to the CSGMember List judgement of self, to concentrated server lookup self neighboring BS information, then come select target base station according to neighboring BS information and strategy and carry out indicating terminal and be redirected.

5. idle pulley exits

If when terminal idle pulley exits, its serving BS is macro station or OSG Femto or the CSG Femto that allows this terminal access, its idle pulley exits flow process and the idle pulley of existing NWG to exit flow process the same so, just its serving BS type becomes more eurypalynous base station (macro station from macro station, or OSG Femto, or CSG Femto, or the Femto of mixed type).Serving BS (macro station, or OSG Femto, or the CSG Femto) mark that generation idle pulley can be exited when idle pulley exits, passes to Anchor PC and preserves.Be CSG Femto if there is the base station exited of idle pulley, but this CSGFemto does not allow this terminal access, this CSG Femto can be redirected terminal idle pulley exits or carry out network reentry to carrying out on the contiguous base station of this CSGFemto.

Different network elements can judge whether to allow current terminal to carry out idle pulley in current preferred base station to exit, the information difference of utilizing when different network elements judges; If preferably base station judgement, preferably base station is according to himself allowing the terminal user identification list CSGMember List of access and terminal user identification to carry out, and anchoring paging controller and anchoring authentication device are to allow the CSG Femto List CSG ID that carry out or that utilize current preferred base station of its access and terminal to allow the CSG ID List of its access to carry out according to the type of current preferred base station, mark and terminal.

Terminal user identification in terminal user identification list can be NAI or MAC Address, or the unique index in this CSG Femto at least.

Recommend new base station also to cry to terminal and be redirected, redirected target BS is according to the neighbor cell configuration of current preferred base station and redirected strategy decision.

If network design or support Femto, each Femto is being deployed to after network, Femto base station self also can obtain and preserve its neighbor base station information, these information comprise base station type, be Femo base station or Macro base station, if Femto base station information also may include Femto base station type, i.e. CSG, OSG, mixed type; If CSG base station can also be preserved this CSG Femto and be allowed access user list CSGMember List; Can select redirected target BS in conjunction with some strategies according to these information.

While being redirected, target BS is selected to be determined by Different Strategies: this CSG Femto might not know the signal strength signal intensity of adjacent area Femto base station around in real time, also not necessarily know whether CSG Femto allows this terminal access around, select macro base station so general while being redirected, because the coverage of macro base station is large and allow all terminals to access; Need to select Femto base station if be redirected, so also will select the Femto base station of OSG type, whether allow this terminal access because this CSG Femto also not necessarily knows CSG Femto around; If need to select Femto base station while being redirected, and know in CSG Femto around which allows the access of this terminal, also can select to allow the CSG Femto base station of this terminal access while being redirected so.

While being redirected, this CSG Femto sends to and in the ranging response message of terminal, should be with following information one of at least: idle pulley exits failure, the prefix index of redirected target BS; Terminal can be initiated idle pulley according to the prefix index of target BS and exit on target BS.

If this CSG Femto does not have configuring adjacent cell information, when CSG Femto does not allow after this user's access according to the CSG Member List judgement of self, to concentrated server lookup self neighboring BS information, then come select target base station according to neighboring BS information and strategy and carry out indicating terminal and be redirected.

6. paging

Current paging is divided into two kinds, and one is single step paging, and another is multistep paging; So-called single step paging is exactly that Anchor PC once initiates paging group all base stations in current terminal place to initiate paging; So-called multistep paging, is divided into little subgroup paging group exactly, and paging range, in the situation that not receiving response, is continued to expand until expand base stations all in paging group in the base station that first the most possible subgroup occurring of call terminal comprises.

According to the paging group division methods described in above-mentioned Section 2, in paging, make full use of terminal and allow the privately owned Femto list information of access to be optimized paging.

The optimization of 6.1 pairs of single step pagings

In all CSG Femto in paging group, only have and allow the CSG Femto base station of this terminal access just to allow access, therefore, in single step paging, beep-page message can not send to the CSG Femto that does not allow this terminal access.Specifically, in the time realizing, there is various ways.

Mode 1:Anchor PC is in the time outwards sending beep-page message, if send message can directly to the base station in paging group, so Anchor PC does not send message to the CSG Femto that does not allow this terminal access;

Mode 2:Anchor PC is in the time outwards sending beep-page message, if send message can not directly to the base station in paging group, be that Anchor PC sends beep-page message to relay PC or local PC, can in beep-page message, bring CSG Femto List or the CSGID List of this terminal;

Mode 3: when relay PC sends beep-page message, if send beep-page message can directly to the base station in paging group, with reference to mode 1, if relay PC sends beep-page message can not directly to the base station in paging group, with reference to mode 2.

Mode 4: local PC always sends beep-page message to the base station in paging group, with reference to mode 1.

Mode 5: if Anchor PC or relay PC should directly send the base station of beep-page message to paging group, with reference to mode 1; Also to send beep-page message to relay PC or local PC, with reference to mode 2.

The optimization of 6.2 pairs of multistep pagings

In network, dispose behind Femto base station, impact on multistep paging is exactly, AnchorPC need to ensure, in each step of multistep paging, can not comprise the CSG Femto base station that does not allow this terminal access, and the beep-page message of each step sends example can be with reference to mode in 3.6.1 1 to mode 5.

In addition, consider CSG Femto characteristic (family or office space), multistep paging can be done specific aim optimization:

Mode 1: if there is the CSG Femto base station (family or office space) of this terminal in paging group, user's most applications can rest on its CSG Femto so, therefore the CSG Femto in this terminal CSG Femto List of the first step of multistep paging in can this paging group of priority paging or in CSG ID List, in the situation that not receiving response, then continue to expand paging range.

Mode 2: mode 1 is made further improvements, in the time sending beep-page message to CSG Femto, first judge whether terminal has larger possibility to be positioned at CSG Femto.The method of judgement can be multiple: upgraded if current terminal is not also carried out position, judge whether Base Station Identification when idle pulley enters is its privately owned Femto base station, if it is can think that terminal current base station still rests in privately owned Femto service range; Upgraded if terminal is carried out position, judged when proximal most position is upgraded, whether Base Station Identification is its privately owned Femto mark, if so, can think that terminal still rests in its privately owned Femto service range; Or setting one carries out continuously position update times thresholding M or continuous position and upgrades and show the time threshold T that stops, on its CSG Femto, carrying out continuous N time position when terminal upgrades, or exceed T in the continuous time of staying of its CSG Femto, network side judges that terminal still rests within the scope of its CSG Femto.Still rest within the scope of its CSGFemto serving BS when network side judges terminal, first step by step paging can first paging judge the CSG Femto that terminal stops; In the situation that not receiving response, expand paging to all privately owned Femto that allows this terminal access in this paging group; In the situation that not receiving response, continue to expand to base stations all in paging group.Or when network side judges that terminal still rests within the scope of its CSG Femto serving BS, the first step is with regard to the privately owned Femto of this terminal access of all permissions in this paging group of paging, in the situation that not receiving response, continue paging and expand base stations all in paging group to.

The method of another paging, determines whether issuing page message by CSG Femto base station exactly.

6.3 rely on CSG Femto self to determine whether send beep-page message to terminal

Adopt in this way, Anchor PC or relay PC or local PC do not need to do any judgement.

If single step paging sends beep-page message to all base stations (comprising Macro BS, Femto) in paging group, do not judge whether CSG Femto wherein allows this terminal access; When CSG Femto receives after beep-page message, judge wherein whether terminal iidentification allows access, if do not allow access, this CSG Femto does not send beep-page message.

If multistep paging in like manner does not need to judge whether the CSG Femto in paging range allows this terminal access in each step yet; But receive after beep-page message as CSG Femto, judge wherein whether terminal iidentification allows access, if do not allow access, this CSGFemto does not send beep-page message.

Below in conjunction with accompanying drawing, the preferred embodiment of each process of the present invention is described.

Anchoring paging controller, relaying paging controller also can send paging notice message to paging agent (being base station); The same with local paging controller, do not send paging notice message to the CSG Femto base station that does not allow this terminal access.

(3) base station receives that paging starts notice message, and base station sends this terminal of paging broadcast message paging by air interface to terminal.

If in step (2), paging controller is in the time sending paging notice message to paging agent, according to the CSG Femto information that allows terminal access, the CSGFemto that will send is not screened, CSG Femto base station also can allow the user list that accesses terminal according to self, does not send paging broadcast message to the terminal that does not allow its access.

(4) terminal is received after paging broadcast message, enters that idle pulley exits or position update flow.

Paging stops

As shown in figure 12, represent the schematic diagram that paging stops.

(1) terminal responds beep-page message under certain base station, completes network and reentries or position update flow; And notice is to anchoring paging controller.

(2) anchoring paging controller sends paging (stopping) notice message to local paging controller; Paging notice message includes the information that this terminal is relevant to Femto, be specifically as follows one of following list: the CSG Femto List or the CSG ID List that allow terminal access, CSG Femto List or the CSG ID List of terminal access in this paging group, in this paging controller administrative area, this locality, allow CSG Femto List or the CSG ID List of terminal access, the CSG Femto List or the CSG ID List that in this paging controller administrative area, this locality and in this paging group, allow terminal to access.

Anchoring paging controller also can send paging notice message to local paging controller by one or more relaying paging controller; Described paging notice message comprises terminal and Femto relevant information is same as above, can think one of following list: the CSG Femto List or the CSG ID List that allow terminal access, CSGFemto List or the CSG ID List of terminal access in this paging group, in message receiver administrative area, allow CSG Femto List or the CSG ID List of terminal access, in message receiver administrative area and in paging group, allow CSG Femto List or the CSG ID List of terminal access.

(3) local paging control is according to receiving paging (stopping) notice message, and the base station in administrative area sends paging (stopping) notice message; Local paging controller does not send paging notice message to the CSG Femto base station that does not allow terminal access;

Anchoring paging controller, relaying paging controller also can send paging notice message to paging agent (being base station); The same with local paging controller, do not send paging notice message to the CSG Femto base station that does not allow this terminal access.

(4) paging (stopping) notice message is received in base station, and base station stops sending this terminal of paging broadcast message paging by air interface to terminal.

Start to stop in flow process with paging anchoring paging controller and will send that the interacting message of base station (paging agent) of beep-page message also can undertake by one or more relaying paging controller in said process paging.

In said process, if relaying paging controller or anchoring paging controller reside in Femto-GW, Femto-GW judges whether to send paging notice message to Femto so.

If one of following base station: OSG Femto, mixed type Femto, macro station, send paging notice message; If CSG is Femto, Femto-GW judges according to following method:

Femto-GW searches the user ID list that allows to access terminal of CSG Femto base station, if terminal user identification, in this list, sends paging notice message; Otherwise do not send paging notice message.Or

Femto-GW searches the CSG Femto List that allows terminal access, if this CSGFemto is positioned at this list, sends paging notice message; Otherwise do not send paging notice message.Or

Femto-GW searches the CSG ID List that allows terminal access, if the CSG ID of this CSGFemto is positioned at this list, sends paging notice message; Otherwise do not send paging notice message.

Position is upgraded

As shown in figure 13, represent the schematic diagram of position update flow.

(1) MS sends distance measurement request message (RNG REQ) to serving BS broadcasts.

(2)-(2a), (2b) serving BS broadcasts receives distance measurement request message, the paging agent on BS can directly or by one or more paging relayings send location update message (LU-Location Update) to anchoring paging controller; If serving BS broadcasts is CSG Femto, serving BS is before sending message to anchoring paging controller, and it can judge whether to allow this terminal position to upgrade, if do not allow this updating of terminal position, directly arrives step (6).

(3) anchoring paging control controller sends context request message (Context Req) to anchoring authentication device and obtains AK Context (Authorization Key, AK Context, i.e. authorization code context); If serving BS broadcasts is CSG Femto, anchoring paging controller is before sending message to anchoring authentication device, and it can judge whether to allow this updating of terminal position, if do not allow this updating of terminal position, directly arrives step (5a).

(4) anchoring authentication device sends Context Rpt, i.e. context report message to anchoring paging controller; If serving BS broadcasts is CSG Femto, anchoring authentication device can judge whether to allow this terminal position to upgrade, if do not allow this updating of terminal position, anchoring authentication device can be refused Context Req, send with the Context Rpt that suitably wrong instruction or failure are indicated, need not be with AK Context simultaneously.

(5)-(5a), (5b) anchoring paging controller to serving BS send position upgrade response message; If serving BS does not allow terminal position to upgrade, response message is upgraded with suitably wrong instruction or unsuccessfully instruction in the position that anchoring paging controller sends, or further with the station list of recommending terminal and can carrying out position renewal.

(6) BS sends ranging response message to MS.If this serving BS does not allow terminal position to upgrade, ranging response message upgrades unsuccessfully with position; And further indicating terminal carries out the initial reentry of network or network reentry, can also further carry out the initial station list of reentrying or reentrying of network with indicating terminal.

In this position updating process, if anchoring paging controller and anchoring authentication device are unified, do not need the interacting message of step (3), (4).

Wherein, in said process, preferred base station type mark when partly or entirely the upgrading with position of following message: 1) location update request message; 2) response message is upgraded in position; 3) context request message; And, 4) context report message.Described base station type mark clearly or impliedly identifies base station and one of belongs to Types Below at least: 1) macro base station; And, 2) Femto base station.If described base station type is Femto base station, the clear and definite or implicit mark of described base station type mark base station one of belongs to Types Below at least: 1) CSGFemto base station; 2) OSG Femto base station; And, 3) the Femto base station of mixed type.

Wherein, in said process, if the preferred base station of position while upgrading is CSGFemto, the CSG ID:1 of preferred base station when partly or entirely the upgrading with position of following message) location update request message; 2) response message is upgraded in position; 3) context request message; And, 4) context report message.

Wherein, in said process, if current preferred base station is CSG Femto base station, current preferred base station judges whether to allow described terminal to carry out position renewal in current preferred base station, after distance measurement request message is received in current preferred base station, according to following message part or all judge whether to allow this terminal to upgrade in this Shang Zuo position, preferred base station: it allows terminal user identification list, the current terminal user identification of access; Determination methods is: preferred base station when position is upgraded finds that terminal user identification allows in the terminal user identification list of access at it, allows position to upgrade, otherwise does not allow position to upgrade;

Wherein, in said process, if anchoring paging controller judges whether to allow described terminal to carry out position renewal in current preferred base station; After anchoring paging controller is received position updating request, according to following message part or all judge whether to allow this terminal enterprising line position upgrades in this preferred base station: the CSG ID of CSG Femto base station when base station type when position is upgraded, Base Station Identification, the CSG Femto List of permission terminal access, position are upgraded, allows the CSG ID List of terminal access; The method of judgement is: anchoring paging controller finds that the Base Station Identification of the preferred base station of upgrading position allows in the CSG Femto List of its access in terminal, allows position to upgrade, otherwise does not allow position to upgrade; Or anchoring paging controller finds that the CSG ID of preferred base station that position is upgraded allows in the CSG ID List of its access in terminal, allow position to upgrade, otherwise do not allow position to upgrade;

Wherein, in said process, if anchoring authentication device judges whether to allow described terminal to carry out position renewal in current preferred base station; Anchoring authentication device is received context request message (Context Req message) afterwards, judge whether to allow the enterprising line position renewal in this preferred base station of this terminal according to following message part or whole position: base station type, Base Station Identification when position is upgraded, allow the CSG Femto List of terminal access, the CSG ID of CSGFemto base station when position is upgraded, the CSG ID List that allows terminal to access.The method of judgement is: anchoring authentication device finds that the Base Station Identification of the preferred base station of upgrading position allows in the CSG Femto List of its access in terminal, allows position to upgrade, otherwise does not allow position to upgrade; Or anchoring authentication device finds that the CSG ID of preferred base station that position is upgraded allows in the CSG ID List of its access in terminal, allow position to upgrade, otherwise do not allow position to upgrade;

In said process, preferably base station (paging agent) and anchoring paging controller interacting message also can be undertaken by one or more relaying paging controller.

In said process, if Femto when preferred base station, directly receive the relaying paging controller of preferred base station transmission location update message (owing to can mutually directly sending message with paging agent, here also can be called local paging controller) or anchoring paging controller reside in Femto-GW, Femto-GW judges whether to allow to upgrade at the enterprising line position of Femto so.

If one of following base station: OSG Femto, mixed type Femto, macro station,, allow to carry out position renewal in described preferred base station; If CSG is Femto, Femto-GW judges according to following method:

Femto-GW searches the user ID list that allows to access terminal of CSG Femto base station, if terminal user identification in this list, allows position to upgrade; Otherwise do not allow position to upgrade.Or

Femto-GW searches the CSG Femto List that allows terminal access, if this CSGFemto is positioned at this list, allows position to upgrade; Otherwise do not allow position to upgrade.Or

Femto-GW searches the CSG ID List that allows terminal access, if the CSG ID of this CSGFemto is positioned at this list, allows position to upgrade; Otherwise do not allow position to upgrade.

Wherein, if described network element judgement allows terminal to carry out position renewal in preferred base station in said process, continue to carry out follow-up flow process.

Wherein, if the judgement of described network element does not allow terminal to carry out position renewal in preferred base station in said process, further comprise carry out in following action one of at least:

Skip follow-up flow process, directly send response message;

Send the response message with suitable wrong instruction or failure cause;

Send the response message that indicating terminal carries out initial network reentry or network reentry; And

Recommend the new base station information that can carry out position renewal to terminal.

Idle pulley exits

As shown in figure 14, the present embodiment is used for illustrating that idle pulley exits schematic flow sheet.

(1) MS sends distance measurement request message (RNG REQ) to serving BS broadcasts.

(2)-(2a), (2b) serving BS broadcasts receives distance measurement request message, the paging agent on BS can directly or send idle pulley exit status by one or more paging relayings to anchoring paging controller and change request message (IM-Exit-State-Change-Req); If serving BS broadcasts is CSG Femto, serving BS is sending before message to anchoring paging controller, and it can judge whether to allow this terminal to carry out idle pulley to exit, if do not allow this terminal idle pulley to exit, directly arrive step (6).

(3) anchoring paging control controller sends context request message (Context Req) to anchoring authentication device and obtains AK Context (Authorization Key, AK Context, i.e. authorization code context); If serving BS broadcasts is CSG Femto, anchoring paging controller is before sending message to anchoring authentication device, and it can judge whether to allow this terminal idle pulley to exit, if do not allow this terminal idle pulley to exit, directly arrives step (5a).

(4) anchoring authentication device sends Context Rpt, i.e. context report message to anchoring paging controller; If serving BS broadcasts is CSG Femto, anchoring authentication device can judge whether to allow this terminal to carry out idle pulley to exit, if do not allow this terminal idle pulley to exit, anchoring authentication device can be refused Context Req, send with the Context Rpt that suitably wrong instruction or failure are indicated, need not be with AK Context simultaneously.

(5)-(5a), (5b) anchoring paging controller sends idle pulley exit status to serving BS and change response message (IM-Exit-State-Change-Rsp); If not allowing terminal to carry out idle pulley, exits serving BS, the idle pulley exit status that anchoring paging controller sends changes response message with suitably wrong instruction or unsuccessfully instruction, or further can carry out with recommending terminal the station list that idle pulley exits.

(6) BS sends ranging response message to MS.Exit if this serving BS does not allow terminal to carry out idle pulley, ranging response message exits failure with idle pulley; And further indicating terminal carries out the initial reentry of network or network reentry, can also further carry out the initial station list of reentrying or reentrying of network with indicating terminal.

Exit in process at this idle pulley, if anchoring paging controller and anchoring authentication device are unified, do not need the interacting message of step (3), (4).

Wherein, in said process, preferred base station type mark when partly or entirely the exiting with idle pulley of following message: 1) idle pulley exit status changes request message; 2) idle pulley exit status changes response message; 3) context request message; And, 4) context report message.Described base station type mark clearly or impliedly identifies base station and one of belongs to Types Below at least: 1) macro base station; And, 2) Femto base station.If described base station type is Femto base station, the clear and definite or implicit mark of described base station type mark base station one of belongs to Types Below at least: 1) CSG Femto base station; 2) OSG Femto base station; And, 3) the Femto base station of mixed type.
