Description

A kind of mobility management method, method of measurement, system and equipment

Technical field

The present invention relates to communication technical field, relate in particular to a kind of mobility management method, method of measurement, system and equipment.

Background technology

In mobile communication network, as the Access Network of bridge between terminal use and core switching network, ability to communicate directly influences the experience of user to the service of moving.The low coverage wireless communication technique more and more comes into one's own with the advantage of high access bandwidth and low communication cost.Popularize just rapidly in the mode of exempting to authorize frequency range that wireless access is provided based on the low coverage wireless communication technique, in local even metropolitan area scope, with the conventional wireless Access Network and deposit.Therefore, the conventional wireless Access Network, for example: UMTS (Universal MobileTelecommunications System, universal mobile telecommunications system) (the UMTSTerrestrial Radio Access Network of the UTRAN in, grounding wireless access network) and GSM (Global Systemfor Mobile communications, global system for mobile communications) and GERAN Access Network (EnhancedData rate for GSM Evolution Radio Access Network, the enhanced data rates Access Network) with employing UMA (Unlicensed Mobile Access, exempt to authorize to move and insert) GAN (GenericAccess Network, universal access network) seamless switching between and roaming become the hot technology of quite being paid close attention to.

Original GAN supports the A/Gb pattern, as shown in Figure 1.And, introduced the GAN (EGAN) of enhancement mode along with the development of technology, and mainly be the Iu pattern that has increased GAN, in order to keep the compatible A/Gb of reservation pattern, as shown in Figure 2, to support seamless switching and the roaming between UMTS and the EGAN.Travelling carriage must at first be registered to GANC (GenericAccess Network Controller by general access IP network (Generic Access IP Network), general access network controller) setting up communication connects, GANC is equivalent to BSS (Base Station Subsystem, base station sub-system)/RNC (Radio Network controller, and general access IP network provides WAP (wireless access point) radio network controller).When GAN network and EGAN network and when depositing, GANC can support A/Gb pattern and Iu pattern simultaneously, and dual-mode terminal also can be supported two kinds of patterns of A/Gb and Iu simultaneously.The GANC of GAN network is referred to as traditional GANC, and the GANC at EGAN networking is referred to as enhancement mode GANC, to show difference.

When initiating GERAN/UTRAN when EGAN switches, if terminal and network are all supported two kinds of patterns, execution is with the switching flow under a kind of pattern, signaling consumption is little comparatively speaking, implementation is simple, as: initiate to switch to the GANA/Gb pattern from GERAN, initiate to switch to GAN Iu pattern from UTRAN.Therefore after introducing EGAN, switch to exist and preferably may.

For the GAN network of only supporting the A/Gb pattern,, therefore can only switch to GAN A/Gb pattern owing to do not support the Iu pattern.For the EGAN network, enhancement mode GANC can support A/Gb and Iu pattern simultaneously, this moment when bimodulus MS (travelling carriage) when GERAN/UTRAN switches to the GAN network, concrete steps may further comprise the steps as shown in Figure 3:

Step s301, MS (Mobile Station, travelling carriage) detects the service of GAN network attached to the GERAN/UTRAN sub-district.

Step s302, MS successfully finish the GAN registration, and this moment, MS may successfully be registered to the GANA/Gb pattern, also may successfully be registered to GAN Iu pattern because GANC has supported A/Gb pattern and Iu pattern simultaneously.

Step s303, after meeting switching condition, cell signal as GERAN/UTRAN is poor, and source BSS/RNC will determine to initiate to switch after receiving the measurement report of MS, actually or switch this moment and depend on fully under which pattern to GANA/Gb pattern Iu pattern and to succeed in registration.

In realizing process of the present invention, the inventor finds to exist in the prior art following shortcoming:

1, in the measurement report that MS reports, owing to just identified GAN sub-district ID, GERAN/UTRAN does not also know it is which kind of pattern, can not determine to use the switching flow of the sort of pattern.

2, in the EGAN network, enhancement mode GANC can support A/Gb pattern and Iu pattern simultaneously, and dual-mode terminal also can be supported two kinds of patterns of A/Gb and Iu simultaneously.When initiating GERAN/UTRAN when EGAN switches, if terminal and network are all supported two kinds of patterns, to switch to GAN A/Gb pattern still be that the Iu pattern is uncontrollable to MS at this moment, which pattern to succeed in registration just switch to which pattern in.If MS initiates to switch from GERAN, the result succeeds in registration under GAN Iu pattern, MS just will switch to GAN Iu pattern from GERAN this moment, switching between the different obviously RAT (Radio Access Technology, wireless access technology) will be more more complex than the switching that GERAN switches between this identical RAT of GAN A/Gb pattern.If MS initiates to switch from UTRAN, can know that in like manner switching to GAN Iu pattern understands fairly simple.

3, at present along with the E-UTRAN sub-district is incorporated into 3GPP as a kind of new Access Network, the GERAN/UTRAN sub-district adopts priority mechanism to be used for mobile management: the precedence information that is issued different Access Networks by network side is given terminal, carried out operations such as sub-district gravity treatment again according to this priority by terminal, network side also can carry out switch decision etc. according to this information.When switching that GAN network and GERAN/UTRAN network take place or gravity treatment, how GAN network or terminal are obtained these precedence informations and are used this precedence information, and prior art does not provide corresponding solution;

4, the control that reports that can measure and measure for the terminal network side of supporting multiple Access Network at present, for example when mobile phone is in GERAN CS single user state, network can transmitting order to lower levels or indication forbids measuring the E-UTRAN sub-district to terminal and the UTRAN sub-district avoids too much measurement and/or measurement to report, yet the scheme of prior art is when the control that reports of measuring and measuring, and terminal can't normally switch to the GAN sub-district.

Prior art can preferably switch to what pattern and uncontrollable for MS, and the therefore increase that can cause switching complexity increases unnecessary spending.Simultaneously prior art do not consider priority mechanism introducing, measure the influence of the introducing of control to the GAN network, make that normal sub-district gravity treatment and switching can't be carried out between GAN sub-district and the GERAN/UTRAN sub-district.

Embodiment

The technical scheme of the embodiment of the invention had both gone for traditional GANC, also went for enhancement mode GANC.Those skilled in the art will appreciate that in the embodiments of the invention to be example explanation technical scheme only, but do not represent the restriction scope of application of the present invention with traditional GANC or strong type GANC.The GANC that is mentioned both can refer to traditional GANC herein, also can refer to enhancement mode GANC.

The embodiment of the invention provides a kind of mobility management method, as shown in Figure 4, may further comprise the steps:

Step s401, travelling carriage sends the mobile management request message to enhancement mode GANC.Carry the mobility management information (being indication information) of described travelling carriage in the described request message, can comprise the preferred general access network pattern of grid of reference type indication information and/or travelling carriage indication information.

Mobile management can be flow processs such as sub-district/network reselection, switching, discovery, registration, register update.

Step s402, the mobile management request message that enhancement mode GANC receiving mobile sends.

Step s403, enhancement mode GANC carry out preferred mobile management according to the indication information in the mobile management request message.As: selection needs the pattern of the general access network of employing, the pattern of acceptance registration.

The grid of reference type indication that request message carries is used for the current accompanying wireless or fixed network of marking terminal, and pattern.

The preferred general access network pattern indication of the travelling carriage that request message carries is used for the pattern that the marking terminal expectation is used.

Enhancement mode GANC is according to these information, can select following one or more combination to carry out mobile management:

If 1 EGAN supports the pattern of grid of reference type indication information institute marking terminal, then preferably allow end under this pattern.If current registered, and not under this pattern, then start flow allows terminal transfer under this pattern, as the register update flow process; If current also unregistered, then allow endpoint registration under this pattern, and the notice terminal.

If the preferred general access network pattern of 2 EGAN supports mobiles then preferably allows end under this preference pattern.If current registered, and not under this pattern, then start flow allows terminal transfer under this pattern, as the register update flow process; If current also unregistered, then allow endpoint registration under this pattern, and the notice terminal.

If 3 EGAN are the grid of reference type indication information and the preference pattern of supports mobile simultaneously, then judge which kind of pattern of employing in conjunction with above-mentioned both informixs.If current registered, and not under this pattern, then start flow allows terminal transfer under this pattern, as the register update flow process; If current also unregistered, then allow endpoint registration under this pattern, and the notice terminal.

If 4 EGAN neither support the pattern of grid of reference type indication information institute marking terminal, the also preferred general access network pattern of supports mobile not, then enhancement mode GANC selects a kind of pattern that oneself can support to carry out mobile management, perhaps it is redirected to new GANC, or the response request refuse information, this mobile management flow process failure of notice terminal.

Embodiment one

Handoff procedure when travelling carriage has not yet registered the GAN network, may further comprise the steps as shown in Figure 5 in the embodiment of the invention one:

Step s501, MS find that under GERAN or UTRAN network the service of EGAN network exists.

Step s502, MS are by GAN registration or register update flow process, and successful oneself is wishing to finish the GAN registration under the preferred pattern.

The specific implementation process is: MS indicates enhancement mode GANC itself to wish preferred which kind of pattern in login request message.MS can directly increase an indicating bit in register requirement, which kind of pattern indication wants to adopt, enhancement mode GANC receives that this request back judges whether to accept register requirement according to the indication of MS, or MS is redirected to suitable GANC, structure as shown in Figure 6, wherein, PGI represents preferred GANC indication, can be set to: the preferred A/Gb pattern of 00 expression, the preferred Iu pattern of 01 expression, 11 expressions do not have preference pattern.Be appreciated that the institute of PGI might value and implication not necessarily have only above-mentioned a kind ofly, for example, can be that the preferred A/Gb pattern of 01 expression, the preferred Iu pattern of 10 expressions, 00 represent not have preference pattern.

The numerical value of this indication is arranged also can be different with order among Fig. 6, this field must increase newly in register requirement (GA-RC REGISTER REQUEST) message, be appreciated that the shared bit position of PGI cell can be any untapped bit position in this message, the bit that takies also can be not just 2, can also be 3bit, 4bit etc., for example, this indication also can be included in the existing field of login request message: among the GANCLASSMARK, represent with present empty bits, as shown in Figure 7: wherein, TGA (Type ofGeneric Access), be used to indicate the travelling carriage universal access network type of application at present, can be set to: 0000 expression does not have wireless network, 0001 expression Bluetooth, 0010 expression WLAN 802.11,1111 expressions do not indicate.GC (GERAN Capable), 0 this mobile MS of expression do not have GERAN ability, 1 this MS of expression that the GERAN ability is arranged.Among the UC (UTRAN Capable), 0 this MS of expression does not have UTRAN ability, 1 this MS of expression that the UTRAN ability is arranged.Among the RRS (RTP RedundancySupport), 0 expression does not support RTP redundancy, 1 to express support for the RTP redundancy.PS HO (PS HandoverCapable), 0 expression MS do not support PS switch to/from GAN pattern, 1 expression MS support PS switch to/from the GAN pattern.Among the PGI (Preferred GANC indicator), 00 expression prefer A/Gbmode, 01 expression Prefer Iu mode, 11 expressions do not have preference pattern, 10 is standby, be appreciated that, the institute of PGI cell might value and implication not necessarily have only above-mentioned a kind of, for example, can be that the preferred A/Gb pattern of 01 expression, the preferred Iu pattern of 10 expressions, 00 represent not have preference pattern.The indication of network based PGI cell, to corresponding GAN pattern, for example, when the preference pattern of PGI indication travelling carriage was the A/Gb pattern, GANC was with the A/Gb pattern of mobile station login to GAN with mobile station login; When the preference pattern of PGI indication travelling carriage was the Iu pattern, GANC was with the Iu pattern of mobile station login to GAN; If PGI expression does not have preference pattern, network can be adjudicated according to other information or strategy, for example according to the source network type of travelling carriage.

Step s503, when MS find to satisfy when switching to the condition of GAN, MS sends handoff request message, triggers switching to enhancement mode GANC; Perhaps when MS found to satisfy gravity treatment to the condition of GAN, MS carried out the gravity treatment of GAN, and changes oneself state, attached to the GAN sub-district.

Before handover trigger, GANC can carry out pattern and proofread and correct, and the mode adjustment of MS to the pattern consistent with cell-of-origin (the current GERAN/UTRAN sub-district of adhering to) under, and then is triggered switching, as use register update flow process.

PGI is the newly-increased content of message among Fig. 7; be appreciated that PGI no matter be to represent, what order represent different preference patterns with field value no matter be in which field; so long as in register requirement, carried above-mentioned indication information, just belong to the scope of the technical program protection.

Embodiment two

In the embodiment of the invention two, after travelling carriage successfully is registered to certain enhancement mode GANC GANC1, in case travelling carriage is because of moving, change reasons such as access point position, initiation switching, want to change the GAN pattern of oneself, can be by register update request (REGISTER UPDATE) message informing GAN network, the GAN network can be handled according to the preference pattern that travelling carriage carries in the register update request message, for example travelling carriage is redirected to other suitable GANC2.The process of this register update may further comprise the steps as shown in Figure 8:

Step s801, MS sends GA-RC REGISTER UPDATE message to enhancement mode GANC, this message as shown in Figure 9, PGI represents preferred GANC indication, the preferred A/Gb pattern of 00 expression, the preferred Iu pattern of 01 expression, 11 expressions do not have preference pattern, 10 is standby.The numerical value of this indication is arranged also can be different with said sequence.

Step s802 if the preference pattern that enhancement mode GANC can not provide this MS to ask then is redirected to it new enhancement mode GANC, sends GA-RC registration redirect message GA-RCREGISTER REDIRECT to MS.

After receiving redirect message, MS is initiated to the register flow path of new GANC again.

Step s803 if the preference pattern that enhancement mode GANC can provide this MS to ask is then accepted register requirement, sends registration to MS and accepts GA-RC REGISTER ACCEPT message.

Registration accepts can to select to carry in the message pattern of current acceptance, as the A/Gb pattern, and the Iu pattern.

PGI is the newly-increased content of message among Fig. 7; no matter be to represent in which field; no matter be what order to represent different preference patterns,, just belong to the scope of the technical program protection so long as in the register update request, carried above-mentioned indication information with field value.

Embodiment three

In the embodiment of the invention three, as shown in figure 10, may further comprise the steps:

Step s1001, GANC receive the register requirement of MS, carry the current accompanying network type of MS in the register requirement, as GERAN, and UTRAN etc.

Step s1002, GANC judges the residing network schemer of MS.Cell ID/Location Area Identification/the information such as Routing Area Identifier of carrying in register requirement/register update request can indicate current MS to be in which kind of RAT, GSM RR/UTRAN RRC State can further identify current MS and be in which kind of service condition, and network can be judged the register requirement that should adopt which kind of pattern to accept MS in view of the above.For example, when the cell ID that comprises in register requirement/register update request message was GERAN Cell identity, GANC arrived the A/Gb pattern with mobile station login; When the cell ID that comprises in register requirement/register update request message was 3G Cell identity, GANC arrived the Iu pattern with mobile station login.GANC can be further judges according to the service condition of travelling carriage, for example when the service condition of travelling carriage is the free time, even the current GERAN network that is in of travelling carriage, GANC also still can be with mobile station login to GANIu pattern (the GANC load of for example working as the Iu pattern be overweight), because this can't have influence on the business continuance of travelling carriage.When the service condition of travelling carriage for activate/proprietary/when connecting, GANC must be with mobile station login to GAN A/Gb pattern, to guarantee professional continuity.

This moment is not because the state that present MS reports comprises the GPRS state, therefore need to increase PS territory state description among the GSMRR/UTRAN RRC State IE, GANC promptly is modified to GSMRR/UTRAN RRC/GPRS State IE, so that can correctly discern the RAT at the current place of MS.This IE comprises GSM RR/UTRAN RRC/GPRS state as shown in figure 11, and what wherein the GPS cell was represented is the state of GPRS, (represents GPRS free time or transmission state) when state value is effective, and portable terminal promptly is in GERAN and covers.Be appreciated that 2 shared bit positions of GPS might not be positions shown in Figure 11, so long as not by other cell use just passable, unappropriated any empty bit among the GRS IE for example, in addition, the GPS cell also not necessarily only accounts for 2 bits, for example can account for 4 or 5 bits or the like.When GPS is that 00 expression GPRS is in idle condition, 01 expression GPRS transmission state, 10 expression unknown states, be appreciated that, the institute of GPS cell might value and implication not necessarily have only above-mentioned a kind ofly, for example, can be 01 to represent the GPRS transmission state, 10 expression GPRS idle conditions, 11 expression unknown states.The concrete implication of Bits1-3 in the GSM RR/UTRAN RRC state comprises: 000 expression GSM RR is in IDLE state; 001 expression GSM RRC is in the DEDICATED state; 010 expression UTRAN RRC is in idle condition; 011 expression UTRAN RRC is in the CELL_DCH state; 100 expression UTRAN RRC are in the CELL_FACH state; 101 expression UTRAN RRC are in the CELL_PCH turntable; 110 expression UTRAN RRC are in the URA_PCH state; 111 expressions are unknown; Other are worth reservation.When this cell represent be effective GSM RR state the time, show that then travelling carriage is in GERAN and covers, when this cell represent be effective UTRAN RRC state the time, show that then travelling carriage is in UTRAN and covers.

GANC can register judgement in conjunction with this dual mode.Travelling carriage reports state and the preferred mode thereof under the GERAN/UTRAN simultaneously, and GANC judges according to certain strategy.For example, when travelling carriage under GERAN covers, just carrying out the CS business, promptly be in CS DEDICATED state, when the preference pattern of travelling carriage was the Iu pattern, in order to keep business continuance as far as possible, GANC still can set up being connected of A/Gb pattern with travelling carriage; And work as travelling carriage under GERAN covers, and be in idle condition, when the preference pattern of travelling carriage is the Iu pattern, the demand of GANC meeting As soon as possible Promising Policy travelling carriage, the GAN that sets up the Iu pattern with travelling carriage is connected.

Certainly, this be a kind of determination strategy for example, the judgement of GANC also might with the configuration of operator, factors such as offered load are considered, not necessarily fully according to above-mentioned judging process.

Embodiment four

In the embodiment of the invention four, as shown in figure 12, may further comprise the steps:

Step s1201, MS are just carrying out CS or PS or DTM business attached to GERAN or UTRAN sub-district, and successfully have been registered on the GAN network.

GAN is when accepting the register requirement of travelling carriage, use different GAN cell IDs to distinguish the different mode of same GAN sub-district, (as using GAN Cell ID1 sign GAN Iu mode cell, use GAN Cell ID2 sign GANA/Gb mode cell), and this information is included in registration accepts to send to travelling carriage in (GA-RC REGISTER ACCEPT) message.After travelling carriage is received above-mentioned GAN sub-district descriptor is kept at this locality.

In order to make mobile management normally to carry out, particularly switch, in GERAN/UTRAN, also need to dispose corresponding information to distinguish.

Step s1202 when MS wants to initiate to switch to GAN, is included in above-mentioned GAN cell ID in the measurement report that reports source network GERAN/UTRAN.GERAN/UTRAN receives the measurement report that carries the GAN cell information, finds corresponding target GAN sub-district and pattern thereof in the mapping table that preserve in advance this locality, and is initiated to the switching flow of GAN, and MS is switched to GAN.As: receive the sign GAN Cell ID1 of sign GAN Iu mode cell, then be initiated to the switching of GAN Iu sub-district; Receive the sign GAN Cell ID2 of sign GANA/Gb mode cell, then be initiated to the switching of GAN A/Gb sub-district.

Embodiment five:

When terminal and network support measurement and the measurement when reporting control under GERAN/UTRAN, terminal or BSS/RNC need this information is notified to GANC.For example when terminal is in the active state of GERAN, and this moment the UTRAN sub-district measurement or measurement report by network and forbid, if terminal is registered to GAN Iu pattern at this moment, because it is the mode that reports that adopts the UTRAN sub-district that the measurement of GAN Iu pattern reports, therefore terminal just can't report the measurement result of this GAN sub-district, even perhaps terminal to report network side think that also this is that the measurement of a UTRAN sub-district reports and ignores, the switching that causes cutting the GAN sub-district can't normally be carried out.Therefore be registered to GAN Iu pattern when terminal but also do not switch, or terminal has not yet registered but when preparing to be registered to GAN, can be according to the foregoing description one, two, three, by notifying the preferred pattern of GANC as mobile management requests such as register requirement, register update requests is GAN A/Gb pattern, this moment, terminal just can normally report the measurement result of GAN sub-district in the mode of GERAN sub-district, guaranteed that the switching of incision GAN sub-district is normally carried out.Similarly, the measurement that is in GERAN UTRAN ACTIVE state this moment when terminal reports when disabled, be registered to GAN A/Gb pattern when terminal but also do not switch, or terminal has not yet registered but when preparing to be registered to GAN, can be GAN Iu pattern by notifying the preferred pattern of GANC according to the method described in the foregoing description as mobile management requests such as register requirement, register update requests.When above-mentioned situation occurs in the process that switching carried out, also can allow source BSS/RNC that this information is sent to GANC.

Embodiment six:

Be to indicate GANC which kind of GAN pattern will be provided in embodiment five by terminal, it can only be a recommendation to GANC that but this method has a shortcoming to be that terminal indicates, if GAN does not support the pattern of recommending or because the strategy of the recommendation pattern that provides of receiving terminal not itself causes the problems referred to above still to exist.Therefore when the GERAN/UTRAN network is measured control,, also need to consider the control that reports of the amount of GAN sub-district and measurement except the control that reports of the measurement of considering the GERAN/UTRAN/EUTRAN sub-district and measurement.Therefore in the present embodiment, in measurement that network (as BSS/RNC) the issues control indication (as described in measurement control indication comprise) for the indication information that reports of measuring and/or measuring, not only indicate the measurement of GERAN/UTRAN/EUTRAN network and/or reporting of measurement, also include the indication that reports to GAN cell measurement and/or measurement, for example BSS/RNC with the dedicated signaling of MS on carry a network control measurement/measurement report cell (Network controlledmeasurements/measurements reporting IE), this cell is used to indicate whether allow the GAN sub-district is measured, and/or whether allow reporting of measuring of GAN sub-district etc., for example, as shown in table 1, whether " GAN " field with this cell indicates whether to allow the GAN sub-district is measured, and/or allow reporting that the GAN sub-district is measured:

Table 1

In " GAN " of this cell field, be the situation that is provided with that example is set forth this field with 2 bit with this fields account:

00 expression is not measured the GAN sub-district, does not report the measurement to the GAN sub-district;

01 expression is measured the GAN sub-district, but does not report;

10 expressions are measured the GAN sub-district and are reported.

Certain above-mentioned field value only is exemplary with corresponding content, does not limit other corresponding relation.

Also can " GAN " field be set to 3 bits, as follows:

000 expression is not measured the GAN sub-district, not reporting measurement;

001 expression is measured GAN A/Gb sub-district, but does not report;

010 expression is measured GAN A/Gb sub-district and is reported;

011 expression is measured GAN Iu sub-district, but does not report;

100 expressions are measured GAN Iu sub-district and are reported;

101 expressions are measured the GAN sub-district, but do not report;

110 expressions are measured the GAN sub-district and are reported.

Certain above-mentioned field value only is exemplary with corresponding content, does not limit other corresponding relation, to realize the function of indication.

" GAN " field that present embodiment is mentioned and situation is set only is exemplary, and present embodiment does not limit title, bit figure place of this indication field or the like, as long as can realize the function of indication.Whether the cell in the present embodiment can also be used for indication is measured other network cell, and/or allow reporting of measuring of other network cell or the like.This cell also can be included in more existing message and send, and for example sends in measuring message such as control messages, system message, assignment messages, switching controls class, also can define a new message structure and be used for sending this indication information specially.This new message structure can be used for indicating separately the measurement/measurement report control of GAN sub-district, also can be to be used to indicate the measurement/measurement of other Access Network to report control.

Accordingly, corresponding with the method for present embodiment, a kind of measuring system also is provided, comprise network side and terminal:

The description of the specific implementation process of the measuring system of the method for application present embodiment and the method for present embodiment is similar substantially, repeats no more herein.

In the present embodiment, by whether the GAN sub-district being measured by issuing, and/or the measurement that the reports control indication of whether the GAN sub-district being measured, carry out reporting of cell measurement and/or measurement according to described measurement control indication, make and measure between GAN sub-district, control back and the GERAN/UTRAN sub-district sub-district gravity treatment and switching and can normally carry out introducing.

Embodiment seven:

The consideration terminal must be used the situation of priority mechanism at GERAN/UTRAN.When mobile phone power-on, might directly not reside under the GAN sub-district because find GERAN/UTRAN to cover, after this when terminal finds that GERAN/UTRAN covers, need gravity treatment to arrive the GERAN/UTRAN sub-district, but can cause terminal can't adopt the priority mechanism gravity treatment to the GERAN/UTRAN sub-district owing to do not obtain precedence information before.The GAN network should provide the precedence information of GERAN/UTRAN to portable terminal in this case.For example in registration or register update flow process, GANC can send to portable terminal with precedence information; Perhaps have under the professional state, precedence information is sent to portable terminal by proprietary connection when terminal is in GAN; Thereby make portable terminal can defer to priority mechanism and carry out mobile management.

When terminal is about to be registered to the GAN network or is in registered but when not having professional state, terminal can be by indicating whether to support priority as mobile management request messages such as register requirement or register update requests to network, carry precedence information at follow-up mobile management response message in as message such as registration/register updates if GANC receives that request back judges that terminal is supported priority and send to terminal, terminal is carried out mobile management such as sub-district gravity treatment based on this precedence information.

Perhaps professional state is arranged when terminal is in, be that terminal has special-purpose the connection through GANC with core net, this moment, core net may send the CAMEL-Subscription-Information indication to GANC, and GANC sends to terminal by the special use connection with precedence information according to the priority value of this CAMEL-Subscription-Information indication and/or local policy setting terminal.

Gravity treatment again when terminal has obtained precedence information under the GERAN/UTRAN pattern after/when switching to the GAN sub-district, terminal can use this precedence information to carry out follow-up mobile management, and directly this information being notified to GANC by the mobile management request message, GANC can provide suitable GAN pattern according to this precedence information.For example the priority that obtains UTRAN when portable terminal under the GERAN/UTRAN pattern is higher than the priority of GERAN, portable terminal is notified to GANC by login request message with above-mentioned precedence information when being registered to GANC, GANC obtains to think after this priority that thereby should the mutually deserved GAN of providing Iu pattern having higher priority with UTRAN is consistent, so GANC can adopt GAN Iu pattern as the pattern of this endpoint registration to GAN.
