Description

The access module changing method of a kind of multimode double-terminal and relevant device

Technical field

The present invention relates to mobile communication technology field, particularly relate to access module changing method and the relevant device of a kind of multimode double-terminal.

Background technology

LTE (LongTermEvolution, Long Term Evolution) it is 3G (3rdGeneration, 3G (Third Generation) Moblie) follow-up evolution technology, with unique technology advantages such as its high data rate, low time delay, the network architecture of optimization, bigger carrier bandwidths, have become as the new generation broadband mobile communication standard of main flow in the world.The early stage of development at LTE, LTE network cannot accomplish comprehensive covering, simultaneously because LTE network is based on full IP (InternetProtocol, procotol) framework, VoIP (VoiceoverInternetProtocol, namely based on the voice transfer of the IP agreement) business based on packet domain can only be provided, therefore, LTE terminal is generally adopted many modular forms, and 3G and 2G network need to be used to carry corresponding business.Simultaneously, in current Mobile Communications Market, due to the consideration based on aspects such as business, flow, rate, personal communication and business practice, increasing user has multiple USIM (UniversalSubscriberIdentityModule of multiple operator, Global Subscriber identification card) block and/or SIM (SubscriberIdentityModule, Subscriber Identity Module) meet the user demand of different aspect, therefore LTE multimode double-terminal has become one of main terminal type of Mobile Communications Market.

Specifically, LTE multimode double-terminal need to be provided with two draw-in grooves, each of which draw-in groove all can be supported to insert usim card or SIM, and can support that multiple identical or different wireless access technology is simultaneously standby and can support that multiple identical or different wireless access technology communicates or timesharing communicates simultaneously.Specifically, the wireless access technology (be alternatively referred to as access module or access standard) that LTE multimode double-terminal is supported can include TD-LTE (TimeDivisionLongTermEvolution, time-division Long Term Evolution)/LTEFDD (FDD Long Term Evolution)/WCDMA (HSPA) (WCDMA, i.e. WidebandCodeDivisionMultipleAccess, WCDMA；HSPA, i.e. HighSpeedUplinkPacketAccess, high-speed uplink packet access technology)/TD-SCDMA (TD-HSPA) (TD-SCDMA, i.e. TimeDivision-SynchronousCodeDivisionMultipleAccess, TD SDMA)/GSM (GPRS/EDGE) (GSM, i.e. GlobalSystemforMobilecommunications, global system for mobile communications；GPRS, i.e. GeneralPacketRadioService, general packet radio service technology；EDGE, i.e. EnhancedDataRateforGSMEvolution, i.e. enhanced data rates for gsm evolution technology)；Two subscriber cards (usim card and/or SIM) used may belong to same operator, it is also possible to belongs to the different operators of home or overseas, and, two subscriber cards used can support one or more access technologies respectively.It addition, in real network, the network type that LTE multimode double-terminal specifically can be accessed by, the aspect such as the wireless access technology generally supported by terminal capability, usim card and/or SIM, local networks traffic-operating period and migration efficiency determines.

At present, in Mobile Communications Market, consideration according to aspects such as the user demand of user, terminal hardware realization, cost and carrier customization strategies, modal a kind of LTE multimode double-terminal has distinguished primary path and secondary path, and two subscriber cards are distributed into main card and vice card (or card 1, card 2 etc.) for access capability and the business function etc. of distinguishing two cards.The primary path of this multimode double-terminal generally can comprise the necessary device such as 4G/3G/2G baseband chip (i.e. the multimode processing module of primary path), radio frequency chip and radio-frequency front-end, and supported wireless access technology can include TD-LTE/LTEFDD/WCDMA (HSPA)/TD-SCDMA (TD-HSPA)/GSM (GPRS/EDGE)；Secondary path generally only comprises the necessary devices such as 2G baseband chip (or 3G/2G baseband chip) (i.e. the multimode processing module of secondary path), radio frequency chip and radio-frequency front-end, can support the access technology (such as GSM or WCDMA/GSM) that one or both bandwidth are less.Additionally, the main card of this multimode double-terminal and the setting of vice card, automatic adaptation can be carried out by multimode double-terminal according to information such as subscriber card type, operator, the geographical position that is presently in, or be realized by the corresponding relation etc. of fixed card slot Yu major and minor card.

Further, for this common LTE multimode double-terminal, generally supporting that main card accesses primary path and uses multiple access technology to realize service communication, vice card then accesses, by secondary path, the communication function that real-time performance is most basic, for instance standby in 2G network or standby in the networking of 3G/2G.Further, the implementation according to terminal, the primary path of this common LTE multimode double-terminal can adopt singly treats that mode or multimode pair treat mode.Wherein, the mode of singly treating adopted can be CSFB (CircuitSwitchFallBack, circuit domain dropping), i.e. main card preferential resident LTE (such as TD-LTE/LTEFDD) network, when there being voice traffic needs, terminal can be fallen back to 3G (such as TD-SCDMA/WCDMA) or 2G (such as GSM) network to provide voice service by redirect or handover mechanism etc. by network, after voice service terminates, terminal can return LTE network based on number of mechanisms from 3G or 2G network.It addition, the multimode that adopts double; two treat that mode may refer to main card can be simultaneously standby and be operated under two kinds of networks of LTE and 3G/2G, or simultaneously standby and be operated under two kinds of networks of LTE/3G and 2G.

Specifically, in the prior art, if multimode double-terminal subscriber card occurs when signal quality is poor or flow arrives the situation restriction uses such as pre-determined threshold, it is possible to be switched on another subscriber card and carry out corresponding business transmission.But, for above-mentioned common multimode double-terminal, owing to its secondary path generally only designs for meeting basic communication requirement, support the access way that bandwidth is less, network is accessed only by 2G or 3G/2G, therefore, when main card occurs that signal quality is poor or flow, when the situation restrictions such as rate use, even if now vice card can support plurality of access modes (such as 4G/3G/2G), but the restriction due to terminal, user can only use 2G or 3G/2G of vice card to access network, cause that the transfer rate that can reach is relatively low, use motility is poor, have a strong impact on the experience of user.

Additionally, when main card occurs that signal quality is poor or the restriction of the situation such as flow, rate uses, if the 2G network signal of vice card is more weak or during local signal without GSM network, secondary path can only use the multimode double-terminal of 2G to will be unable to use, and can reduce using motility and then reducing the experience of user further of terminal further.

Detailed description of the invention

For prior art Problems existing, the application accesses the multimode double-terminal of network based on secondary path only by 2G or 3G/2G, propose the handover scheme of the access module of a kind of multimode double-terminal, the program can not revised on the basis of hardware configuration of existing multimode double-terminal, reaches following purpose:

Occur that signal quality is poor or owing to the problem such as rate, flow cannot normally use at main card, vice card can with and vice card can support except the access module that secondary path is supported other one or more access modules when, the access capability of extension vice card, vice card is made to be no longer influenced by the restriction of the access module that secondary path is supported, other access technologies carrying business that vice card self is supported can be used, thus the actual access capability of vice card can greatly be extended, improve the motility of terminal occupation mode.

In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.

Embodiment one:

The embodiment of the present invention one provides the access module changing method of a kind of multimode double-terminal, as it is shown in figure 1, it is the schematic flow sheet of the access module changing method of multimode double-terminal described in the embodiment of the present invention one, described method can comprise the following steps that

Step 101: if it is determined that the main card of multimode double-terminal cannot normally use, and determine that the vice card of described multimode double-terminal is in upstate and described vice card support other at least one access modules except the access module that the secondary path of described multimode double-terminal is supported, the PLMN frequency list then indicating the carrier network relevant to described vice card that the primary path of described multimode double-terminal prestores according to described vice card or described multimode double-terminal is set the web search of access module, wherein, described setting access module refers to that described secondary path is not supported but the access module of described vice card support.

Specifically, if it is determined that there is the signal quality caused due to covering problem lower than pre-determined threshold (even no signal covering) in the main card of described multimode double-terminal, or during the problem such as rate, flow etc. be limited, it is believed that the main card of described multimode double-terminal cannot normally use.

Further, primary path in order to reduce described multimode double-terminal performs the number of times of web search, after the main card determining multimode double-terminal cannot normally use, and before the PLMN frequency list of the carrier network relevant to described vice card indicating the primary path of described multimode double-terminal to prestore according to described vice card or described multimode double-terminal is set the web search of access module, described method may also include that

That is, more preferably, when determining that main card is owing to covering problem signal quality is lower than thresholding set in advance, or owing to the problem such as rate, flow cannot normally use and lasting one section of duration set in advance, and when determining vice card is in upstate and vice card (or vice card type) can be supported except secondary path access capability other one or more wireless access technologys, multimode double-terminal just can enter corresponding access module switching state, to extend the actual access capability of vice card.

It should be noted that, in embodiment of the present invention, when extending the actual access capability of vice card, in order to ensure or improve the efficiency of transmission of data, preferably, when main card cannot normally use, the actual access capability of extension vice card generally may refer to switch over vice card to the access module of bigger bandwidth, switches to secondary path by vice card and does not support but in access module higher the priority that possesses of the access module supported of vice card support and the relatively secondary path of priority that possesses.

Such as, assume that the priority of access module is from high to low for 4G, 3G, 2G, if secondary path supports that 2G accesses, vice card supports 4G/3G/2G, the actual access capability then extending vice card generally may refer to switch to vice card 4G/3G access module, that is, may indicate that the corresponding 4G/3G available cell of the PLMN frequency list search of the carrier network relevant with described vice card that the primary path of described multimode double-terminal prestores according to described vice card or described multimode double-terminal；If secondary path supports that 2G accesses, vice card supports 3G/2G, the actual access capability then extending vice card generally may refer to switch to vice card 3G access module, that is, may indicate that the corresponding 3G available cell of the PLMN frequency list search of the carrier network relevant with described vice card that the primary path of described multimode double-terminal prestores according to described vice card or described multimode double-terminal；Or, if secondary path supports that 3G accesses, vice card supports 4G/3G/2G, the actual access capability then extending vice card generally may refer to switch to vice card 4G access module, that is, may indicate that the corresponding 4G available cell of the PLMN frequency list search of the carrier network relevant with described vice card that the primary path of described multimode double-terminal prestores according to described vice card or described multimode double-terminal.

Certainly it should be noted that if secondary path supports that 3G accesses, vice card supports 4G/3G/2G, when then extending the actual access capability of vice card, vice card also can be switched to 4G or 2G access module, i.e. vice card can be switched to secondary path and do not support but in arbitrary access module of vice card support.

Additionally, it should be noted that, in embodiment of the present invention, when the primary path of described multimode double-terminal carries out corresponding web search, usually utilizing the 4G/3G/2G baseband chip (i.e. multimode processing module) in described primary path to carry out, this is not repeated by the embodiment of the present invention.

Step 102: if it is determined that described primary path searches available setting access module community, it indicates that described primary path is linked in the setting searched network corresponding to access module community.

Specifically, if searching available setting access module community, then described primary path can according to corresponding instruction, perform corresponding attachment flow or perform tracing section updating (TAU, 4G network) or Routing Area Update, location area updating (RAU, LAU, 3G network) etc. operation, be linked in the network of correspondence, so that described vice card can be passed through described primary path and be linked in corresponding setting access module network.

Namely, in technical scheme described in the embodiment of the present invention, when determining that main card cannot normally use and vice card is in upstate and described vice card support other at least one access modules except the access module that secondary path is supported, user can pass through primary path and use one or more wireless access technologys that vice card is supported to carry out corresponding business transmission, the restriction of the access module no longer supported by secondary path, thus extending the actual access capability of vice card, improve the motility of terminal occupation mode.

It should be noted that in actual applications, when main card cannot normally use, the actual access capability of vice card specifically can be extended to which kind of or which plant access module, can be realized by terminal, network environment and carrier policy etc. are many-sided determines.

Such as, if described primary path adopts and singly treats mode (such as CSFB), then when main card cannot normally use, when carrying out the extension of vice card actual access capability in the manner described above, described vice card can be resided in any one setting access module that vice card is supported by described primary path according to the custom strategies of operator, network environment and business demand etc.；Similarly, if described primary path adopts, multimode is double; two treats mode, then when main card cannot normally use, when carrying out the extension of vice card actual access capability in the manner described above, described vice card can be resided in any two kinds of setting access modules that vice card is supported by described primary path according to the custom strategies of operator, network environment and business demand etc..

Specifically can be as, (it is likely to comprise TD-LTE if the supported wireless access technology of vice card includes 4G, one or more in LTEFDD), 3G (is likely to comprise TD-SCDMA, WCDMA, one or more in CDMA2000), 2G (such as GSM), secondary path only comprises 2G module (namely only supporting GSM), then, now, the access technology that vice card is actual only has 2G, and this is a kind of, correspondingly, when main card cannot normally use, when carrying out the extension of vice card actual access capability in the manner described above, if primary path adopts and singly treats mode (such as CSFB), then vice card can according to carrier customization strategy, network environment and business demand etc. reside in a network of 4G/3G/2G；If primary path adopts, multimode is double; two treats mode, then vice card can reside according to carrier customization strategy, network environment and business demand etc. in two networks of 4G/3G/2G.

Certainly, it should be noted that set access module community as time multiple when what described primary path searched, can priority height corresponding to each access module, the of a relatively high access module community of prioritizing selection priority is accessed, and this is not repeated by the embodiment of the present invention.
