Will also be understood that, this the first communication pattern support at least two kinds of network formats, namely this first communication pattern has multiple network formats ability, such as, the network formats of the first communication pattern support is LTE/TD-SCDMA/GSM, namely shows that the first communication pattern has the ability of all frequency ranges of LTE/TD-SCDMA/GSM, but synchronization, terminal is such as attached on LTE or on TD-SCDMA or GSM can only be attached to a network formats under the first communication pattern under.

Will also be understood that, this terminal supports circuit domain dropping CSFB function under this first communication pattern, wherein, circuit domain dropping (Circuit Switched Fallback, referred to as CSFB) specifically refer to, such as terminal resides in Long Term Evolution (Long Term Evolution, referred to as LTE) network, when CS territory business such as needs process voice services, fall back to circuit switching (the Circuit Switched of 2G/3G network, referred to as CS) territory completes CS territory business, and under current resident LTE network only deal with data business, can realize reusing existing CS territory network investment like this for the terminal in LTE network provides traditional C/S territory business, the CS territory that namely can make full use of 2G/3G network provides voice for the terminal resided under LTE network, note, CS territory business is waited in location.CSFB technology is current known technology, and for simplicity, the idiographic flow for CSFB does not repeat them here.

Will also be understood that, in embodiments of the present invention, the network formats that the second communication pattern that terminal is supported is supported supports CS territory business, this second communication pattern can support multiple network support, such as second communication pattern has the ability of all frequency ranges of TD-SCDMA/GSM, also can support a kind of network formats, such as second communication pattern has the ability of all frequency ranges of GSM or TD-SCDMA, and the embodiment of the present invention is not limited thereto.

In S110, determine that this terminal only opens the first communication pattern, and determine the first network standard not support circuit-switched CS territory business that this terminal is adhered under this first communication pattern, this first network standard is a kind of network formats at least two kinds of network formats supporting of this first communication pattern.Particularly, terminal is only standby and under being operated in the first communication pattern, under namely synchronization can only be operated in a kind of network formats; In embodiments of the present invention, such as terminal is current to be attached in first network standard, such as LTE network standard.Wherein, the first network standard not support circuit-switched CS territory business that this terminal is adhered under this first communication pattern is determined.Such as can determine this first network standard not support circuit-switched CS territory business according to following two kinds of scenes.

Scene one: such as terminal current resident first network standard be LTE, LTE can provide high-speed data service, but LTE can not provide the CS territory business such as voice service, at this moment terminal cannot provide the CS territory business such as voice service under LTE network, namely can determine that this first network standard does not support CS territory business;

Scene two: also for first network standard for LTE, when this terminal supports circuit domain dropping (Circuit Switched Fallback under the first communication pattern, referred to as CSFB) function time, namely when needs process CS territory business, the CS territory business such as speech are carried out in the CS territory can falling back to 2G/3G network by LTE, namely, under terminal is only operated in the first communication pattern, PS territory business and CS territory business can be processed simultaneously.But when the access network of LTE network and the access network of 2G/3G network (such as GSM/TD-SCDMA) do not have overlapping covered, do not support CSFB, namely in this case, the CS territory of falling back to 2G/3G network (such as GSM/TD-SCDMA) from LTE cannot be realized, and then terminal cannot provide CS territory business, namely can determine that this first network standard does not support CS territory business.Hereafter will elaborate to this scene.

Should understand, above-mentionedly just determine that first network standard does not support the situation of CS territory business for first network standard for LTE illustrates, this first network standard can also be other network formats, can be such as the network formats of certain support PS territory business of the 5G that may occur in the future, the embodiment of the present invention be not construed as limiting this.

When determining that the first network standard of current attachment does not support CS territory business, remove the CS territory professional ability of this terminal under this first communication pattern, namely go to enable the CS territory ability of this terminal under the first communication pattern, make terminal only responsible data service under the first communication pattern.

In S120, remove the CS territory professional ability of this terminal under this first communication pattern, concrete finger, terminal is under the first communication pattern, under no matter being attached to which kind of network formats at least two kinds of network formats that the first communication pattern supports, its CS territory professional ability is all removed, namely in terminal under the first communication pattern, no matter current be attached to which kind of network formats under, all cannot perform CS territory business.

In S130, activate this second communication pattern and support second network standard, and activate the CS territory professional ability of this terminal under this second communication pattern, this second network standard is different from this first network standard, and this second network standard supports CS territory business.Particularly, second communication module is switched to mode of operation by offline mode, can by carrying out start-up logging to second communication pattern, to activate second communication pattern, and activate second communication pattern support second network standard, wherein this second network standard is different from this first network standard, and this second network standard supports CS territory business, will also be understood that this second network standard can be single network formats, such as GSM or TD-SCDMA or WCDMA, also can be multi-mode networks, such as GSM/TD-SCDMA or GSM/WCDMA, the embodiment of the present invention is not construed as limiting this.Will also be understood that, this second communication pattern is set and supports second network standard, it is also understood that as second communication pattern default setting supports multiple network standard, when second communication module is switched to mode of operation by offline mode, only activate one or more network formats in the multiple network standard that this second communication pattern default setting supports.Open the CS territory professional ability of this terminal under this second communication pattern, specifically refer to possess CS territory professional ability when terminal is attached in second network standard under second communication pattern.Here can be understood as is that all-network standard to second communication pattern is supported carries out the registration of CS territory, also the subnetwork standard that can be understood as in the all-network standard only supported second communication pattern carries out the registration of CS territory, and the embodiment of the present invention is not construed as limiting this.

The technology that the idiographic flow that terminal carries out the registration of CS territory under second communication pattern is well known to those skilled in the art, for simplicity, repeats no more here.

Carry out the registration of CS territory under this second communication pattern after, the Indication message of the communication pattern change being used to indicate terminal can also be sent to network side (core net).

Alternatively, as an embodiment, after the CS territory professional ability of this terminal of this unlatching under this second communication pattern, the method also comprises:

The 3rd Indication message is sent to core net, 3rd Indication message is used to indicate this terminal and opens this second communication pattern, also be used to indicate this second communication pattern and support this second network standard, be also used to indicate this terminal, under this second communication pattern, there is CS territory professional ability.

Particularly, such as can upgrade (Location Area Up, referred to as LAU) flow process by the position district triggering second communication pattern, send the 3rd Indication message.The position district triggering second communication pattern upgrades (Location Area Up, referred to as LAU) flow process, it can be specifically international mobile subscriber identity attachment (International Mobile Subscriber IdentificationATTACH, referred to as the IMSI ATTACH) flow process triggering second communication pattern.Should be understood that the 3rd Indication message also for the professional ability of informing this second communication pattern of core net and the network formats that can support, so that core net provides accordingly

Before unlatching second communication pattern, the network formats that the first communication pattern is supported can also be reset.

Alternatively, as an embodiment, before this second communication pattern of this activation supports second network standard, the method also comprises:

Remove one or more network formats except this first network standard at least two kinds of network formats that this first communication pattern supports, at least two kinds of network formats that this first communication pattern is supported change to the 3rd network formats, and the 3rd network formats is different from this second network standard.

Particularly, such as at least two kinds of network formats of the first communication pattern support are LTE/TD-SCDMA/GSM, the first network standard of present terminal attachment is LTE, then can remove network formats TD-SCDMA or GSM or TD-SCDMA/GSM, the embodiment of the present invention is not construed as limiting this, only otherwise go the first network standard of enable current attachment, such as, do not remove enable LTE(disableLTE), under the first communication pattern, again do not search net.

This second network standard is different from the 3rd network formats, particularly, the at least two kinds of network formats also supported in the first mode of communication are LTE/TD-SCDMA/GSM, the first network standard of present terminal attachment is LTE is that example is described, as the network formats GSM of removal first communication pattern, namely the 3rd network formats supported of current first communication pattern is LTE/TD-SCDMA, then the second network standard of second communication pattern support is GSM; Again such as, as the TD-SCDMA/GSM of removal first communication pattern, the 3rd network formats supported of current first communication pattern is LTE, then the second network standard of second communication pattern support can be set to GSM or TD-SCDMA or TD-SCDMA/GSM.

When terminal by be only operated in the first communication pattern switch to be operated under the first communication pattern and second communication pattern simultaneously time, be set to by the network formats that second communication pattern is supported different from the network formats that the first communication pattern is supported, be conducive to terminal provides CS territory business better under second communication pattern.

Should be understood that above-mentioned TD-SCDMA can also replace with WCDMA.

Alternatively, as an embodiment, the 3rd network formats is Long Term Evolution LTE network standard and TD SDMA TD-SCDMA network standard, and this second network standard is global system for mobile communications GSM network standard; Or

3rd network formats is LTE network standard and Wideband Code Division Multiple Access (WCDMA) WCDMA, and this second network standard is GSM network standard; Or

3rd network formats be LTE network standard and GSM network standard time, this second network standard is TD-SCDMA or WCDMA; Or

3rd network formats is LTE network standard, this second network standard is GSM network standard, or this second network standard is TD-SCDMA network standard, or this second network standard is WCDMA network formats, or this second network standard is GSM network standard and TD-SCDMA network standard, or this second network standard is GSM network standard and WCDMA network formats.

When also can not support CSFB according to the first network standard of current attachment, determine that this first network standard does not support CS territory business, remove the CS territory professional ability of the first communication pattern.

Terminal possesses circuit domain dropping CSFB function under the first communication pattern, when current attach to network can not support CS territory business, the CS territory can falling back to 2G/3G network provides CS territory business, when but if the Radio Access Network of current attach to network standard and the Radio Access Network of 2G/3G network do not repeat overlay area, the CS territory that terminal just cannot fall back to 2G/3G network provides CS territory business, needs the CS territory professional ability of removal first communication pattern.

Alternatively, be embodiment as one, determine to comprise the first network standard not support circuit-switched CS territory business that this terminal is adhered under this first communication pattern:

Determine that this first network standard does not support this CSFB function;

Determine that this first network standard does not support CS territory business.

Particularly, such as this first network standard is LTE, when the Radio Access Network of LTE and the Radio Access Network of 2G/3G network of determining current attachment do not have overlapping covered, can determine that resident LTE network does not support this CSFB function, particularly, can be determined by attachment/tracing section updating (Combine Attach/Tau) flow process of combining of LTE network.

Alternatively, as an embodiment, determine that this first network standard does not support this CSFB function, comprising:

Send a request message to core net, this request message is registered for asking the attachment/tracing section updating of combining of this first network standard;

Receive the response message that this core net sends according to this request message, this response message is used to indicate any one situation in following situations:

C, only standby and under being operated in TD-SCDMA (TD-HSPA)/GSM (GPRS/EDGE) network, or only standby and under being operated in TD-LTE network;

D, under international roaming scene, terminal need possess LTE/WCDMA/GSM CSFB ability (specific requirement refers to " LTE/TD-SCDMA/GSM multi-mode terminals specification---singly treat fascicle " relevant regulations), also need to possess simultaneously and realize domestic two ability treating that CSFB scheme automatically switches under single deck tape-recorder scheme and international roaming scene according to public land mobile network (Public Land Mobile Network, referred to as PLMN) change.

Wherein, in a and b situation, terminal is in two pattern to be communicated; In c situation, terminal is in single pattern to be communicated.

2) related content of type 2 terminal

1. type 2 terminal is that multimode pair treats single card terminal, and CS territory is registered on GSM, and GSM also comprises: GPRS/EDGE; PS territory is registered on LTE/TD-SCDMA, and wherein TD-SCDMA also comprises TD-HSPA;

2. type 2 terminal needs to possess following ability:

D, under international roaming scene, recommends to increase simultaneously standby and under being operated in LTE and WCDMA/HSPA network ability on this basis, or the only standby and ability that is operated under WCDMA (TD-HSPA)/GSM (GPRS/EDGE) network.If adopt CSFB scheme under international roaming scene, then terminal need possess LTE/WCDMA/GSM CSFB ability (specific requirement refers to " LTE/TD-SCDMA/GSM multi-mode terminals specification---singly treat fascicle " relevant regulations), also needs to possess to realize two ability that single deck tape-recorder scheme and CSFB scheme automatically switch for the treatment of according to PLMN change simultaneously.

Multimode is two treats that single card terminal can be connected by the mobile communication system that air interface is simultaneously different from two, and then completes whole business continuing end to end.

Multimode is two treats that single card terminal treats therefore there are two radio frequencies because needs support is two.Suppose that radio frequency 1 has the ability of all frequency ranges of LTE/TD-SCDMA/GSM, the Software Protocol Stack be operated on radio frequency 1 can be called the first communication pattern.Suppose that radio frequency 2 has the ability of all frequency ranges of GSM or TD-SCDMA/GSM, the Software Protocol Stack be operated on radio frequency 2 can be called second communication pattern.

Corresponding types 2 terminal, speech business is selected to register/be based upon GSM(GPRS) module, TD-LTE/TD-SCDMA module is registered/be based upon to data service prioritizing selection, terminal leaves the TD-LTE/TD-SCDMA area of coverage, or TD-LTE/TD-SCDMA pattern cannot provide normal data traffic support, then select at GSM(GPRS) singly treat Module registers/foundation/data reconstruction business.

(U) SIM card of Multi-mode dual-standby terminal is identical with general single mode terminal, and two two patterns treated are according to the relevant parameter district of respective flow operations same (U) SIM card.When two patterns operate (U) SIM card simultaneously, terminal control two sequence of modules operations, avoid conflict.When a pattern operates certain parameter region, if this parameter region is two patterns share parameter region, the operation that terminal can control a pattern does not affect the data under another pattern.
