Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method and subscriber equipment safeguarding PLMN information.
Background technology
3GPP(The 3rd Generation Partnership Project third generation partners cooperation) propose a kind of subscriber equipment (User Equipment, UE) carry out to realize speech business (voice service) scheme that public Land Mobile Network (Public Land Mobile Network, PLMN) selects.Concrete: if comprise " IMS voice not available " (IMS(IP MultimediaSubsystem in the PLMN selected by UE, IP Multimedia System) speech business is unavailable), and this PLMN does not support CSFB(Circuit Switched Failback, circuit-switched service falls after rise), then UE needs its E-UTRAN(Evolved UMTS(Universal Mobile Telecommunications System of first deexcitation, universal mobile telecommunications system) Terrestrial Radio Access Network, evolution UMTS Terrestrial radio access network) ability (i.e. disable E-UTRAN capability), and then select other RAT(Radio Access Type of this PLMN, wireless access type), as GERAN(GSM/EDGE Radio AccessNetwork, GSM(Global System for Mobile communication, global system for mobile communications)/EDGE(Enhanced Data Rates for GSM Evolution, GSM evolution enhanced data rates for GSM evolution) wireless access network) or UTRAN access,
If this PLMN does not have GERAN/UTRAN network, UE, according to the priority (priority) of PLMN, selects other PLMN, and detailed process is see 3GPP TS23.122 agreement; In this selection course, UE needs again to activate its E-UTRAN ability (i.e. re-enable E-UTRANcapability), specifically see 3GPP TS24.301.
Current 3GPP(3rd Generation Partnership Project, 3G (Third Generation) Moblie standardization body) " the IMS voice not available " of agreement regulation comprise following situation:
1, UE does not configure and uses IMS;
2, UE does not configure and uses IMS voice, and voice domain hobby (the voice domain preference for E-UTRAN) instruction namely arranged for E-UTRAN in UE can only be passed through circuit commutative field (CSdomain) and obtain speech business (voice service);
3, UE configuration uses IMS voice, but network does not support IMS voice;
4, UE configuration uses IMS voice and network support IMS voice, but the upper strata of UE:
4a. does not provide this UE can use the instruction of IMS audio call (IMSvoice call) within the cycle of definition of dispatching from the factory;
4b. indicates this UE can not use IMS audio call.
There is following problem in the scheme that above-mentioned UE carries out PLMN selection:
If the RPLMN selected can not provide IMS speech business before, then UE reselects PLMN according to priority, but because the priority of RPLMN is the highest, therefore, UE is when carrying out PLMN and selecting, RPLMN before still likely choosing, thus produce ping-pong (namely UE may ceaselessly select identical PLMN under given conditions), make UE cannot obtain CS speech business, for this reason, a solution is also been proposed in 3GPP agreement, concrete: UE keeps in the PLMN information (information) that can not provide IMS speech business, be designated as: " PLMNs not preferred for voice service " (PLMN for speech business is not recommended), UE is made to carry out in the process of PLMN selection follow-up, can according to the PLMN information stored, get rid of corresponding PLMN, specifically see 3GPP TS24.301 and 3GPP TS23.122.
Also specify in existing 3GPP agreement and like (voicedomain preference for E-UTRAN according to the voice domain of E-UTRAN in UE, VDP for E-UTRAN) and the configuration information of UE, determine whether to delete the PLMN information stored, specifically see 3GPP TS24.301.At present, the change situation of the VDP of E-UTRAN in this UE is only considered in the maintenance of UE to the PLMN information that it stores, concrete: the value of the voice domain hobby arranged for E-UTRAN in UE become only IMS packet domain voice (that is: IMS PS voice only) time, delete all PLMN information of its storage;
Its PLMN information stored when is deleted about UE, prior art further discloses: when the value of the voice domain hobby arranged for E-UTRAN in UE becomes any other value from " IMS PS voice only " or " CS voice only(namely only circuit domain voice) ", delete all PLMN information that it stores; When its value from " CS voice preferred; IMS PS voice as secondary(and preferred circuit territory voice; and secondaryly select IMS packet domain voice) " or " IMS PS voice preferred; CS voice as secondary(and preferred IMS packet domain voice; and secondaryly select circuit domain voice) " when becoming any other value, then do not delete the PLMN information that it stores.
But, such scheme is in implementation process, due in UE for E-UTRAN arrange voice domain hobby value become " IMS PS voice only " time, all PLMN information in deletion " PLMNs not preferred for voiceservice " list (such as, PLMNA), cause UE when carrying out PLMN and selecting, the PLMNA that IMS speech business can not be provided can be reselected to, thus this UE performs again the operation of its E-UTRAN ability of deexcitation, the PLMN information of this PLMNA is recorded in " PLMNs not preferred for voice service " list, when the value that the voice domain arranged for E-UTRAN in this UE is liked changes, the PLMN information of PLMNA in delete list once more, cause new ping-pong (ping-pong).
Illustrate: suppose for a certain UE, comprise PLMNA and PLMNB in its PLMN list, wherein, PLMNA supports IMS voice, but it does not have GERAN and UTRAN network; PLMNB supports CSFB and has GERAN/UTRAN network; Have following setting for this UE: the value of the voice domain hobby arranged for E-UTRAN in this UE as " IMS PS voice only ", the HPLMN(home PLMN of UE, Home PLMN) be PLMNA, then:
First, because the priority of PLMNA is higher, UE is attached to PLMNA, in this PLMNA, if UE is IMS speech business down state (upper strata as this UE indicates it can not use IMS audio call), then its E-UTRAN ability of UE deexcitation, again because PLMNA does not have GERAN and UTRAN network, therefore, in " PLMNsnot preferred for voice service " list that the PLMN information of this PLMNA stores stored in self by UE;
Then, UE is according to priority, other PLMN are selected to access (as have selected PLMNB), then in the selection course of this PLMNB, again activate its E-UTRAN ability, if now, the value that the voice domain arranged for E-UTRAN in UE is liked becomes " IMS PS voice only ", according to the regulation of existing 3GPP agreement, UE will delete the PLMN information of PLMNA from " PLMNs not preferred for voice service " list;
Finally, if PLMNB can not provide IMS speech business for UE, then this UE is when reselecting PLMN, and because PLMNA is HPLMN, its priority is high, and therefore, UE can choose PLMNA again, and again performs said process.
In sum, in prior art, because UE is only according to the change of the value of its voice domain hobby arranged for E-UTRAN, determine whether to delete its PLMN information that speech business can not be provided stored, make UE in the process of carrying out PLMN selection, easily there is ping-pong, thus cause the selection course of unnecessary PLMN, thus reduce treatment effeciency.
