Step 103, utilize the tabulation of described tracking area that described terminal is entered common sub-district to carry out mobile management, utilize described closed user group move options that described terminal is entered the closed subscriber group (CSG) sub-district and carry out mobile management.

MME specifically can utilize tracking area tabulation and closed user group move options that terminal mobile carried out control and management, can also utilize tracking area to tabulate and the closed user group move options carries out paging to terminal.

In the concrete application of network system, according to the difference that the closed user group move options is formed, the difference of control mode, the embodiment of the invention realize in different ways, below in conjunction with different situations the embodiment of the invention are further specifically described.

In following each embodiment, mobile management is tabulated by being generated according to terminal positional information by MME.Described mobile management tabulation can be TA List, CSG mobility List (closed user group move options) etc., and wherein, what TA List write down is TA information.

Embodiment two,

Referring to Fig. 2, be a kind of network attachment flow chart that the embodiment of the invention provides, step can be as follows:

Step 201, terminal send the network attachment request message to MME;

Terminal can send the network attachment request message to network side by the base station when network insertion, can comprise user ID, customer position information etc. in the described network attachment request message.Customer position information can be the terminal TA information of visit recently, and the cell information of sub-district, terminal place etc. can also be adhered in the base station in described network attachment request message when transmitting terminal to network attachment request message that MME sends.

Step 202, MME send network attachment to terminal and accept message.

The information such as user ID that MME can comprise according to described network attachment request message are finished user's network attachment, and can send network attachment to terminal by the base station and accept message, and described network attachment accepts can comprise in the message mobile management tabulation.

In the present embodiment, CSG mobility List record be TA information, the TA of CSG mobility List record can be the some or all of of the TA that write down of TA List.Enter moving of common sub-district with TA list control user, enter moving of CSG sub-district with CSG mobility list control user, just free subscriber between common sub-district move and the user moves to control whether initiate TAU by TA list from the CSG sub-district to common sub-district, the user between the CSG sub-district and the user move by CSG mobility list control whether initiate TAU from common sub-district to the CSG sub-district.

Referring to Fig. 3, be a kind of TA position view that the invention process provides.

As shown in Figure 3, TA List defined range comprises TA1, TA2, three tracking areas of TA3, and statement can be expressed as TA List TA List{TA1, TA2, TA3} for convenience.

HeNB1, HeNB2, HeNB3, HeNB4, HeNB5 represent the Home eNodeB in the TA List defined range respectively, and wherein HeNB1, HeNB2, HeNB3 belong to TA1; HeNB4 belongs to TA2; HeNB5 belongs to TA3.Certainly, can also comprise several ordinary base station (not drawing among Fig. 3) in TA1, TA2, the TA3.

For example, terminal is carried out network attachment in the sub-district of TA1, the mobile management tabulation that terminal obtains can be TA List{TA1, TA2, TA3} and CSG mobility List{TA1}, wherein, CSG mobility List defined range is the part of TA List institute defined range, but is not limited to this.

Accordingly, the TAU flow process can also be arranged.

Referring to Fig. 4, be a kind of TAU flow chart that the embodiment of the invention provides, step can be as follows:

Step 401, terminal send the TAU request message to MME;

Terminal sends the TAU request message by the base station to network side, can comprise user ID, customer position information etc. in the described TAU request message.Customer position information can be the terminal TA information of visit recently, and the cell information of sub-district, terminal place etc. can also be adhered in the base station in this message when transmitting terminal to offered load request message that MME sends.

If terminal moves to new common sub-district, utilize TA List whether described common sub-district is belonged to the defined zone of TA List and judge, if terminal is not initiated the TAU flow process, if not, terminal is initiated the TAU flow process.

If terminal moves to new CSG sub-district, utilize CSG mobility List whether described CSG sub-district is belonged to the defined zone of CSG mobility List and judge, if terminal is not initiated the TAU flow process, if not, terminal is initiated the TAU flow process.

Step 402, MME reply TAU to terminal and accept message.

After MME receives the TAU request message, according to the cell information of terminal latest position information and described sub-district, can tabulate, and described mobile management tabulation is accepted to send to terminal in the message attached to TAU for the mobile management that terminal distribution is upgraded.

Below, referring to Fig. 3, the mode of the present embodiment terminal being initiated the TAU flow process by example is illustrated, and certainly is not limited to the mode of implementing of lifting.

For example, the mobile management tabulation that terminal has obtained is: TA List{TA1, TA2, TA3} and CSG mobility List{TA1}.

Terminal is at TA List{TA1, and any common moving between cells in the TA2, TA3} defined range perhaps moves to TA1 from the CSG sub-district, TA2, and the TAU flow process is not initiated in the common sub-district of TA3; Terminal moves to the CSG sub-district in the CSG mobility List{TA1} defined range from any sub-district, do not initiate the TAU flow process.

If terminal moves to the CSG sub-district the TA2 from the sub-district of TA1, because TA2 does not belong to the defined range of CSGmobility List{TA1}, terminal is initiated the TAU flow process, and MME upgrades CSG mobilityList, for example can be updated to CSG mobility List{TA2}; If terminal moves to the CSG sub-district the TA3 from the sub-district of TA1, because TA3 does not belong to CSG mobility List{TA1}, terminal is initiated the TAU flow process, and MME upgrades CSG mobility List, for example can be updated to CSG mobility List{TA1, TA3}.

If terminal is from { sub-district of TA3} moves to { TA1 for TA1, TA2, TA2 is during any sub-district beyond the TA3}, because terminal has shifted out the defined range of TA list, terminal is initiated the TAU flow process, and MME provides new TA List and CSG mobility List to terminal.

When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TA list defined range, and all Home eNodeB call terminals in the CSG mobility list defined range; The Home eNodeB call terminal that in perhaps MME all ordinary base station in user's TA list defined range, and CSG mobility list defined range all allow described terminal to insert.

Need to prove that in the present embodiment, TA List and CSG mobility list use common TA, the TA that CSG mobility list uses can be the some or all of of the employed TA of TA List.When CSGmobility list was identical with the defined zone of TA List, MME can only issue TA List, and terminal is not initiated the TAU flow process in any moving between cells in the defined zone of TA List.When MME need carry out paging to the terminal of idle condition, MME can all ordinary base station and all Home eNodeB in the TAlist defined range carry out paging; Perhaps all ordinary base station in the TAlist defined range and all Home eNodeB of allowing this terminal to insert carry out paging.

As can be seen, utilize TA List and CSG mobility list, MME can carry out effective mobile management to terminal, for example can make things convenient for, and paging fast is to terminal.Further, TA List and CSGmobility list use common TA, make that the process of mobile management is more simple.

Embodiment three,

Referring to Fig. 2, concrete steps can be as follows equally:

Step 201, terminal sends the network attachment request message to MME;

When network insertion, terminal can send the network attachment request message to network side by the base station, can comprise user ID, customer position information etc. in the described network attachment request message.Customer position information can be the terminal TA information of visit recently, and the cell information of sub-district, terminal place etc. can also be adhered in the base station in this message when transmitting terminal to offered load request message that MME sends.

Step 202, MME send network attachment to terminal and accept message.

The user ID that MME can comprise according to described network attachment request message etc. information, finish user's network attachment, and can accept message to terminal transmission network attachment by the base station, described network attachment accepts can comprise in the message mobile management tabulation.

The network attachment flow process of present embodiment and embodiment two described network attachment flow processs are similar, and difference is that the composition mode of the CSG mobility List that MME provides is different with embodiment two.

CSG mobility List is made up of CSG ID (closed user group id), different with the TA of expression geographic concepts, CSG ID is and the irrelevant logical concept in geographical position, corresponding one or more Home eNodeB of CSG ID, a plurality of Home eNodeB with identical CSG ID can be distributed in different TA, and even the zone of different TA list definition is among the different PLMN (PLMN).For entering moving of common sub-district, terminal judges whether to initiate TAU according to TA list, for entering moving of CSG sub-district, whether initiates TAU by TA list and the common control of CSG mobility list.MME control CSG mobilitylist specifically which CSG ID is made of.Certainly, the mode of utilizing CSG ID to form CSG mobility List can have multiple, and present embodiment is illustrated with dual mode wherein, but is not limited to this.

Mode one,

In the mode one, CSG mobility list is made up of the CSG ID tabulation of the Home eNodeB correspondence that partly or entirely allows terminal to insert in the TAlist defined range.For example MME is according to the current location of terminal, and the pairing CSG ID of several Home eNodeB that will be adjacent with terminal location forms CSG mobility list.

Equally, utilize Fig. 3 to be illustrated, as shown in Figure 3, HeNB1 has identical CSG ID with HeNB4, represents with CSG1; HeNB2 has identical CSG ID with HeNB5, represents with CSG2; The CSG ID of HeNB3 correspondence represents with CSG3.The zone of TA List definition is { TA1, TA2, TA3} still.

If terminal is from the TA2 access network, MME can provide TA List{TA1 to terminal, TA2, TA3} and CSG mobility List{CSG1}; If terminal is from the TA3 access network, MME can provide TA List{TA1 to terminal, TA2, TA3} and CSG mobility List{CSG2}; If terminal is from the TA1 access network, MME can provide TA List{TA1 to terminal, TA2, TA3} and CSG mobility List{CSG1}, perhaps TA List{TA1, TA2, TA3} and CSG mobility List{CSG2}, perhaps TA List{TA1, TA2, TA3} and CSG mobility List{CSG2, CSG3}; Perhaps TA List{TA1, TA2, TA3} and CSG mobility List{CSG1, CSG3, CSG3} etc., above-mentioned situation is for illustrating, and actual conditions are not limited to this.

Accordingly the TAU flow process can also be arranged.

Referring to Fig. 4, concrete steps can comprise equally:

Step 401, terminal send the TAU request message to MME;

Present embodiment TAU flow process and embodiment two described TAU flow processs are similar, terminal can send the TAU request message to network side by the base station, can comprise user ID, customer position information etc. in the described TAU request message, described customer position information can be the terminal TA information of visit recently, the cell information of sub-district, terminal place etc. can also be adhered in the base station in this message when transmitting terminal to offered load request message that MME sends.

If terminal moves to new common sub-district, terminal can be utilized TA List whether described common sub-district is belonged to the defined zone of TA List to judge, if terminal is not initiated the TAU flow process, if not, terminal sends the TAU flow process.

If terminal moves to new CSG sub-district, whether the described CSG of terminal judges sub-district is in TA list defined range, and whether in the coverage of the Home eNodeB of the CSG ID correspondence that CSG mobility List comprises, if, terminal is not initiated the TAU flow process, if not, terminal sends the TAU flow process.

Step 402, MME reply TAU to terminal and accept message.

Below, still referring to Fig. 3, be illustrated by the TAU flow process mode of instantiation to the mode one of present embodiment three, certainly be not limited to the mode of implementing of lifting.

For example, as shown in Figure 3, the mobile management tabulation that terminal obtains is TAList{TA1, TA2, TA3} and CSG mobility List{CSG1}.

Any common moving between cells of terminal in TA1, TA2, TA3, perhaps terminal moves to common sub-district from the CSG sub-district, does not initiate the TAU flow process; Terminal moves in the TA list defined range from any sub-district, and { HeNB1, the TAU flow process is not initiated in the CSG sub-district that HeNB4} covers to the corresponding Home eNodeB of CSG mobility List{CSG1}.Aforesaid way only for for example, is not limited to this.

If terminal moves to { the CSG sub-district beyond the corresponding Home eNodeB coverage of CSG1}, for example terminal moves to the CSG sub-district that HeNB2 or HeNB5 cover, initiate the TAU flow process, MME can be updated to CSG mobility List{CSG1} CSG mobility List{CSG2}, perhaps directly be updated to CSG mobility List{CSG3, CSG2}.

{ the TAU flow process is initiated in TA1, any sub-district beyond the TA2, TA3}, and MME upgrades TA List and CSG mobility List if terminal moves to.Equally, aforesaid way only for for example, is not limited to this.

When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TAlist defined range that terminal obtains, and all Home eNodeB call terminals of supporting CSG ID among the CSG mobility list.

Need to prove, in the mode one of present embodiment, be to form by the CSG ID of the part Home eNodeB in the TA List defined range with CSG mobility List to be illustrated, but be not limited to this.Can also be that CSG mobility List is made up of the CSG ID of all the Home eNodeB correspondences in the TAList defined range.For example, mobile management is tabulated and can is, TA List{TA1, and TA2, TA3}, CSG mobilityList{CSG1, CSG2, CSG3}, move any sub-district of terminal in TA1, TA2, TA3, can not initiate the TAU flow process.When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TAList defined range that terminal obtains, and all Home eNodeB call terminals in the TAList defined range, perhaps MME can be to all ordinary base station in the TA List defined range that terminal obtains, and all the Home eNodeB call terminals that allow terminals to insert in the TAList defined range.

Mode two,

Be that with the difference of mode one in the mode two, when terminal network adhered to, the CSGmobility List initial content that MME distributes can be sky, the variation of the CSG sub-district that moves to along with terminal increases the content of CSG mobility List dynamically.

For example, when terminal moved to a new CSG sub-district for the first time, terminal was initiated the TAU flow process, and MME adds the CSG ID of new CSG sub-district correspondence among the CSG mobility List to, more the CSG mobility List of new terminal.When terminal moves to a new CSG sub-district at every turn, can initiate the TAU flow process, MME can add the CSG ID of described sub-district correspondence among the existing C SG mobility List, if terminal moves to the CSG sub-district of the Home eNodeB covering of supporting CSG mobility List once more, terminal is not initiated the TAU flow process.

Below, equally referring to Fig. 3, be illustrated by the mode of instantiation to present embodiment mode two TAU flow processs, certainly be not limited to the mode of implementing of lifting.

For example, if terminal is adhered to by the ordinary base station access network in TA1, TA2, the TA3, the mobile management tabulation of acquisition can be: TA List{TA1, and TA2, TA3} and CSG mobility List{} perhaps only comprise TA List{TA1, TA2, TA3}; If terminal is adhered to by the Home eNodeB access network, the CSG mobility List of acquisition can comprise the CSG ID of described Home eNodeB correspondence.

Below with terminal from TA1, TA2, the ordinary base station access network of TA3 is illustrated, the mobile management tabulation that obtained of terminal just is TA List{TA1, TA2, TA3} and CSG mobilityList{}.

The common moving between cells of terminal in TA1, TA2, TA3 do not initiated the TAU flow process; When terminal moves when being stationed a new CSG sub-district first, terminal is initiated the TAU flow process, for example, when terminal moves to the CSG sub-district of HeNB1 covering first, terminal is initiated the TAU flow process, MME is with the existing C SG mobility List of the CSG ID interpolation of this CSG sub-district correspondence, mobile management tabulation after the renewal can be CSG mobility List{CSG1}, because Home eNodeB (HeNB1, HeNB4) all support CSG1, (terminal is not initiated the TAU flow process for HeNB1, the CSG sub-district that HeNB4) is covered if terminal moves to once more; If when terminal moved to the CSG sub-district of HeNB2 covering, terminal was initiated the TAU flow process, MME upgrades CSG mobility List{CSG1}, for example can be updated to CSG mobility List{CSG1, CSG2}; If when terminal moves to the CSG sub-district of HeNB3 covering, can initiate the TAU flow process again, MME upgrades CSG mobility List{CSG1, and CSG2} for example can be updated to CSG mobilityList{CSG1, CSG2, CSG3}.

The CSG sub-district that terminal moves to is many more, the CSG ID quantity that CSG mobility List comprises may be also just many more, the CSG ID quantity that MME can comprise CSG mobility List as the case may be rationally controls, for example, MME can limit the maximum quantity of the CSG ID that CSG mobility List comprises, specifically can adopt first in first out, when the quantity of CSG ID exceeds, can be with the CSG ID deletion of adding at first, certainly can also be according to the access time, statistical properties such as access times are rationally controlled the quantity of the CSG ID that CSG mobility List comprises.

Certainly, if terminal moves to TA List{TA1, TA2, during sub-district beyond the TA3} defined range, terminal is initiated the TAU flow process, MME can be terminal distribution new TA List and CSG mobility List, and the initial content that the new CSG mobility List of described acquisition is comprised can be sky.

When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TAlist defined range that terminal obtains, and all Home eNodeB call terminals of supporting the CSG ID that CSG mobility list comprises.

As can be seen, utilize TA List and CSG mobility list, MME can carry out effective mobile management to terminal, for example can make things convenient for, and paging fast is to terminal.Further, CSG mobility list is made up of CSG ID, makes the composition mode variation of CSG mobility list.

Further, utilize the mode two described methods of present embodiment, can when terminal moves to certain CSG sub-district for the first time, check that whether terminal has authority professional in this sub-district application, therefore can carry out more effective control to the business of terminal.

Embodiment four,

Referring to Fig. 2, concrete steps can be as follows equally:

Step 201, terminal sends the network attachment request message to MME;

Step 202, MME send network attachment to terminal and accept message.

The information that MME can comprise according to described network attachment request message is finished user's network attachment.And can accept message to terminal transmission network attachment by the base station, and described network attachment accepts can comprise in the message mobile management tabulation, and described mobile management tabulation can be TA List, CSG mobility List etc.

Be that with the difference of the foregoing description MME is two CSG mobilityList{CSG of terminal distribution mobility List 1, CSG mobility List 2}.Wherein, CSG mobility List 1 can be identical with the type of the CSG mobility List described in the embodiment two, and CSG mobility List 1 is made up of TA, and update mode is similar with embodiment two described CSG mobility List; CSG mobility List 2 can be identical with the type of embodiment three described CSG mobility List, and CSG mobility List 2 is made up of CSGID.

Accordingly, the TAU flow process can also be arranged.

Referring to Fig. 4, concrete steps can be as follows equally:

Step 401, terminal send the TAU request message to MME;

Similar with embodiment two or embodiment three described TAU flow processs, terminal can send the TAU request message to MME by the base station, can comprise user ID, customer position information etc. in the described TAU request message, customer position information can be the terminal TA information of visit recently, the cell information of sub-district, terminal place etc. can also be adhered in the base station in this message when transmitting terminal to offered load request message that MME sends.

Step 402, MME reply TAU to terminal and accept message;

Equally, the information that MME can comprise according to described TAU request message is finished the TAU of terminal.And can reply TAU to terminal by the base station and accept message, can accept the tabulation of the mobile management after the attachment update in the message at TAU, described mobile management tabulation can generate according to customer position information.

In the present embodiment, terminal can obtain two CSG mobility List and a TA List.The update mode of TA List can be similar with the update mode of the TA List described in the embodiment two; The update mode of CSG mobilityList 1 can be identical with the update mode of the CSG mobility List described in the embodiment two; The update mode of CSG mobility List 2 can be identical with the update mode of the CSG mobility List described in the embodiment three.It can be separate that CSG mobility List 1 and CSG mobility List 2 upgrade.

Below, equally referring to Fig. 3, be illustrated by the mode of instantiation to present embodiment TAU flow process, certainly be not limited to the mode of implementing of lifting.

For example, the mobile management tabulation that terminal has obtained is: TA List{TA1, TA2, TA3}, CSG mobility List 1{TA1}, CSG mobility List 2{CSG1}.

Terminal is in any common moving between cells of TA1, TA2, TA3, and perhaps the CSG sub-district in TA1, TA2, TA3 moves to common sub-district, does not initiate the TAU flow process; Terminal is in the public CSG moving between cells of CSG mobility List1{TA1} and CSG mobility List 2{CSG1}, perhaps move to the public CSG sub-district of CSG mobility List 1{TA1} and CSG mobility List 2{CSG1}, do not initiate the TAU flow process from common sub-district.

For example, terminal moves to the CSG sub-district that HeNB4 covers, and terminal is initiated the TAU flow process, and MME upgrades CSG mobility List 1{TA1}, for example can be updated to CSG mobility List 1{TA2}, perhaps CSG mobility List 1{TA1, TA2}.

If terminal moves to the CSG sub-district that HeNB2 covers, terminal is initiated the TAU flow process, and MME upgrades CSG mobility List 2{CSG1}, for example can be updated to CSG mobility List 2{CSG2}, perhaps be updated to CSG mobility List 2{CSG1, CSG2}.

If terminal moves to the CSG sub-district that HeNB3 covers, terminal can be initiated the TAU flow process, and MME upgrades CSG mobility List 2{CSG1}, for example can be updated to CSG mobility List 2{CSG3}, perhaps be updated to CSG mobility List 2{CSG1, CSG3}.

If terminal moves to the CSG sub-district that HeNB5 covers, terminal can be initiated the TAU flow process, MME can be updated to CSG mobility List 1{TA1} CSG mobility List 2{TA3}, CSGmobility List 2{CSG1} is updated to CSG mobility List 2{CSG3}, perhaps CSG mobilityList 2{CSG1} is updated to CSG mobility List 2{CSG1, CSG3}.

Need to prove, above-mentioned situation is only for illustrating, because it can be separate that CSG mobility List 1 and CSGmobility List 2 upgrade, update mode according to embodiment two and enforcement three described CSGmobility List, a lot of variations can also be arranged, be not limited to this.

When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TAlist defined range that terminal obtains, and the public household base station calling terminal of CSG mobility list 1 and CSG mobility list 3.

As can be seen, utilize TA List and CSG mobility list, MME can carry out effective mobile management to terminal, for example can make things convenient for, and paging fast is to terminal.Further, MME is two CSG mobility of terminal distribution list, and is more flexible in the application.

Further, utilize the described method of present embodiment, MME can need reduce the quantity of paging base station relatively when terminal is carried out paging, improved the efficient of paging terminal.

Embodiment five,

Referring to Fig. 2, concrete steps can comprise equally:

Step 201, terminal sends the network attachment request message to MME;

Step 202, MME send network attachment to terminal and accept message.

The information that MME can comprise according to described network attachment request message is finished user's network attachment.And can accept message to terminal transmission network attachment by the base station, described network attachment accepts can comprise in the message mobile management tabulation.

In this enforcement, TA List and CSG mobility List can use independently tracking area separately, and the renewal of TA List and CSG mobility List can be relatively independent.

For example, the mobile management tabulation that terminal has obtained is: TA List{TA1, TA2, TA3}, CSG mobility List{TA4, TA7}.

If terminal moves to the CSG sub-district of TA4 or TA7 from any sub-district of TA1, perhaps terminal moves to the common sub-district of (TA1, TA2, TA3) from the common sub-district of TA1, and terminal is not initiated the TAU flow process; If terminal moves to the common sub-district of (TA1, TA2, TA3) from the CSG sub-district of TA4 or TA7, perhaps terminal moves to the CSG sub-district of TA4 or TA7 from the CSG sub-district of TA4 or TA7, and terminal is not initiated the TAU flow process.

If terminal from the common sub-district of TA1 or the CSG sub-district of (TA4, TA7) move to the CSG sub-district of TA6, terminal is initiated the TAU flow process, MME can be updated to CSG mobility List{TA6} with CSG mobility List{ TA4, TA7}; If terminal from the common sub-district of TA1 or the CSG sub-district of (TA4, TA7) move to the CSG sub-district of TA5, terminal can be initiated the TAU flow process, MME can be updated to CSGmobility List{TA4, TA7} CSG mobility List{TA5}.

If terminal moves to (TA1, TA2, TA3) CSG sub-district in addition from the common sub-district of TA1 or the CSG sub-district of (TA4, TA7), terminal can be initiated the TAU flow process, and MME can upgrade CSG mobility List; If terminal from the common sub-district of TA1 or the CSG sub-district of (TA4, TA7) move to (TA1, TA2, TA3) common sub-district in addition, terminal can be initiated the TAU flow process, MME can upgrade TA List, aforesaid way only for for example, is not limited to this.

When MME need carry out paging to the terminal of idle condition, MME can be to all ordinary base station in the TAlist defined range that terminal obtains, and all Home eNodeB call terminals of CSG mobility list defined range, perhaps MME can be to all ordinary base station in the TA list defined range that terminal obtains, and all Home eNodeB call terminals that allow terminals to insert of CSG mobility list defined range.

As can be seen, utilize TA List and CSG mobility list, MME can carry out effective mobile management to terminal, for example can make things convenient for, and paging fast is to terminal.Further, TA List and CSGmobility List use relatively independent TA respectively, and the composition mode of mobile management tabulation is more simple.
