Description
Technical field
The present invention relates to a kind of mobile station equipment, particularly relate to a kind of travelling carriage and changing method thereof that can between two mobile networks, freely switch.
Background technology
Mobile communication has a dream always, be the whole world to be communicated with by mobile radio communication, the mode that solves is nothing but two, the one, mobile radio communication is made up by a standard, global mobile phone is all in a standard, under same standard, mobile phone certainly is communicated with at any time, yet this imagination is unlikely, the 3G (Third Generation) Moblie international standard has had CDMA2000, WCDMA, three standards of TD-SCDMA, and in very many zones, two standards and to deposit be inevitable.There has been cdma network in China, and its development adopts the standard possibility of CDMA2000 very big, and huge GSM net, for WCDMA has created the bigger market space, and China also must not abandon the standard TD-SCDMA standard that oneself proposes.Many in the world in fact places, densely inhabited district, rely on CDMA2000 and WCDMA to carry out transfer of data, the number of users of supporting is less, can not solve among a small circle that the multi-user uses problem simultaneously, in this case, the time division multiple access of TD-SCDMA just is one and replenishes preferably, therefore, in considerable country, the following 3G standard that adopts will be more than 2 or 2.The unified basis of realizing that the whole world is communicated with of some leading standards has not existed.
And at present, domestic mobile communications network just has two kinds of standards three to throw the net, i.e. GSM standard and CDMA standard, GSM 130,131,132 networks of CHINAUNICOM, CDMA 133 networks, and GSM 134,135,136,137,138,139 networks of China Mobile.And present regular handset all is a single mode, or is the GSM standard, or is the CDMA standard.With a mobile phone, the user can only use the service of a kind of standard, a telephone number and a network.The user wants to change net, or need change number, or just must change mobile phone and number simultaneously.
And another realizes the possibility of whole world mobile phone UNICOM solving exactly on terminal, and dual-mode handset or three mould mobile phones are the basic roads that solve.So-called dual-mode handset is meant can be operated under two network schemers, can support the mobile phone of two kinds of network communications technologys simultaneously.It can therefrom make a choice according to the needs of environment or practical operation: which network technology more can play a role, and just allows mobile phone switch to the work of going down of the sort of pattern.If mobile communication is of low quality or other bad communication phenomenons occur in one mode, just can freely forward work under the another one network schemer to.In fact dual-mode handset is exactly the comprehensive advantage of having utilized two heterogeneous networks, thereby enlarges the voice frequency of mobile phone, and improves the stability of communication greatly.In addition, mobile communications network by 2G in the evolution process of 3G, also can make 2G user easily enjoy the powerful data that 3G network can provide and use.
This two covers network both can be present GSM and CDMA, Personal Handyphone System PHS and GSM, also can be present 2G, 2.5G and following 3G, even can be two kinds of different 3G standards, as TD-SCDMA and CDMA2000.Its advantage is to take into account two networks simultaneously.It can comprise following several types:
Type one: Personal Handyphone System and GSM compatibility; By the dual-mode handset that technological innovation brings, both made the user enjoy the rate advantage of Personal Handyphone System, can experience the network advantage of GSM again, especially using at 3G becomes under the prerequisite of future development trend.
Type two: CDMA and GSM compatibility; In fact allow manufacturer to utilize two mobile phones of a chip manufacturing.It includes enough circuit, can be used in the network that CDMA standard and GSM standard are used in production simultaneously.
Type three: second generation mobile communication system and 3-G (Generation Three mobile communication system) compatibility; Can be in GSM (or CDMA) and 3G standard (may be in TD-SCDMA, WCDMA, three standards of CDMA2000 one or more) two cover systems seamless transfer, work swimmingly.
On the other hand, because the surge of cellphone subscriber's quantity, caused the mobile communication network system to be in the overload operation state, this final result will cause mobile phone the time to be easy to occur being similar in communication going offline, cross-talk, speech quality are bad, be difficult to phenomenon of the failure such as online.In order to solve top phenomenon of the failure, there are increasing mobile phone operators and manufacturer to come to realise this point now, and constantly take measures on customs clearance and come further dilatation cell phone network system, voice quality when improving mobile communication, this also impels many mobile phone manufacturers on the GSM of maturation network foundation, released the dual-mode handset of supporting GSM network and cdma network simultaneously again, although this dual-mode handset just comes out, but because its appearance makes the mobile phone based on GSM, CDMA be come true by dream.Use the GSM/CDMA dual-mode handset, the user can freely be switched between GSM and CDMA, can avoid call drop in the past effectively, and problems such as conversation difficulty and lower tone only use the conversation of GSM net convenient than before.
Because the GSM/CDMA dual-mode handset can be operated among the network of two different technologies simultaneously, so dual-mode handset combines the advantage of these two kinds of network technologies undoubtedly.The appearance of dual-mode handset, for the user, impression will be the darkest undoubtedly, to be again most realistic simultaneously, because the use dual-mode handset, by the roaming of GSM/CDMA network, the call drop phenomenon will significantly reduce, throw into and get free more, the user can also obtain all advantages of two kinds of network technologies simultaneously.
Present bimodulus travelling carriage (dual-mode handset) has following four kinds of purposes:
One, make international roaming more convenient.The main CDMA technology of using of country such as Korea S, North America, European countries mainly use the GSM technology, and does not past have truly global unimpeded.Bimodule service makes GSM user need not the number of changing of changing planes, just can be implemented in countries such as CDMA Korea S in vogue, North America and realize the netsurfing service, and the European Region that CDMA user also can seamless roam holds sway to the GSM network, random zone is far longer than the area that the single mode mobile phone of any one original domestic standard can be roamed.This is maximum beneficiary for the user who often goes abroad.
Two, switch at any time better, on the more cheap network.The user can freely be switched between cdma network and GSM network according to network quality, conversation rate and other needs.Domestic have many proficiency to take GSM mobile handset, takes " rush-harvesting and rush-planting " user of CDMA mobile phone on the other hand, can all put into two draw-in grooves to two mobile phone cards behind the use dual-mode handset, and therefore two mobile phones also unite two into one.
Three, make GSM user when keeping former basic service, can enjoy CDMA1X accurate 3G wireless data service at a high speed.The 2.5G upgrade of network GPRS of GSM is owing to be subjected to technical limitations, and average speed of surfing the Internet only is 20K～30K, and the average 70K～80K of CDMA1X network transmission speed, is 3～4 times of GPRS, also faster than the 56K that dials up on the telephone.Technical seeing, CDMA1X network have very big professional advantage on wireless data service, can realize the seamless link with the Internet.For example, people can enjoy the various data services of CDMA1X network with dual-mode handset, as can the WAP online, browse news, inquire about various informations; Can and any the Internet mailbox between send out mutually and reach 5000 words, the multimedia mail of annexes such as Word, TXT, picture can be arranged; Can download all kinds of mobile phone games, also can download study class contents such as recite words; Can determine the position of oneself and all places information of periphery accurately with positioning function; Can also be connected with data wire notebook computer with dual-mode handset, people are surfed the web whenever and wherever possible ... this often is that for those user of wireless Internet access speed worry, dual-mode handset can allow several SIM cards in its hand give play to advantage separately.
Four, realized the number reservation function.Phone number is precious resources for a lot of people, does not also wish to change number even change net.Yet domestic at present because interconnected, the restriction of multiple factors such as inter-network settlement and government regulation means, also be difficult to realize real " reel number networking ".Dual-mode handset has two plug-in card draw-in grooves, can insert two mobile phone cards simultaneously, and the user can freely select a use mobile phone card wherein according to the needs of oneself, and another Zhang Kake is by being provided with the realization calling transfer.And two cards of dual-mode handset can shared yellow pages and note mailbox.Like this, the user who needs to keep two phone numbers just can easily settle with a dual-mode handset just without having carried two mobile phones all day.This is undoubtedly of great use for the user of those phonovision books such as life.
But present dual-mode handset also can't solve the simultaneously online difficult problem of two numbers, if under the GSM network state, when others dialed your CDMA card number, what hear was the prompt tone of shutdown; If under the cdma network state, when others dialed your GSM card number, what hear also was the prompt tone of shutdown.Therefore, though dual-mode handset can two nets No. two, wanting accomplishes to send a telegram here one does not leak, and calling transfer must be set.Though dual-mode handset is provided with hot key handoff functionality very easily, the user must pay the calling transfer expense for this reason.
Obviously, if weed out the portability of two numbers of bimodulus binding, do not cancel two calling transfer expenses between number, the attraction of dual-mode handset of extracting " moisture " is limited, and it can not simultaneously online defective fatal keeping in check especially.
Following dual-mode handset will develop, a major issue that must solve is communicated with online problem when being heterogeneous networks, each network is accomplished to interconnect, and could allow the user use dual-mode handset, by freely selecting and autonomous the switching, really enjoy the advantage of heterogeneous networks, allow the user status that has the initiative, if do not accomplish to be communicated with simultaneously online, the dual-mode handset user can only use bimodulus in a net, user's selection space will be dwindled greatly, and the development of dual-mode handset will be a greater impact.
Therefore, how to realize that many networks are simultaneously online, and reach freely switching between the network, rather than switch, thereby realize that the multi-section mobile phone is simultaneously online, rather than two mobile phones are online in turn by manual intervention.Realize above function, accomplished really between the heterogeneous networks that at 3G connected sum switches, accomplished that a mobile phone wanders through the world, become the problem of present mobile device solution that manufacturer presses for.

Fig. 2 is the circuit diagram that travelling carriage of the present invention is realized double-module double-standby.
Embodiment
As shown in Figure 1, show the structure of travelling carriage of the present invention (mobile phone), the draw-in groove 101,102 that it comprises client's identification card that two mobile networks are installed at least is used to insert client's identification card of two different communication networks, as inserting client's identification card of net A and two mobile networks of net B; Frequency monitoring module 50 is used to monitor the frequency of mobile network; Handover module 60 is used for switching to another mobile network from the mobile network of travelling carriage work at present; Periodic monitor module 80, whether be used for another mobile network of periodic monitor has the signal paging; Responding module 90 is used to respond described signal paging, and wherein this responding module includes memory, and storage needs the data message of response.Certainly, also comprise some travelling carriages realize its function self-contained some functional modules, as receiver module 10, transmitter module 20, processing and display module 30, input module 40 etc., these all belong to the prior art category, do not repeat them here.Same, travelling carriage of the present invention not only can be used between GSM net and the CDMA net, also can be used between the PHS net and CDMA net/GSM net of Personal Handyphone System, or even between a present mobile network and the following mobile network, also be, these two draw-in grooves can be installed client's identification card of GSM net, client's identification card of CDMA net, client's identification card, GSM and the combinations in twos such as the bimodulus card of CDMA two nets and client's identification card of other mobile networks of PHS net (Personal Handyphone System), and these are not as limitation of the present invention.
This frequency monitoring module 50 switches to this mobile network by this handover module 60 immediately and carries out work behind the paging signal that monitors from mobile network.Simultaneously, whether these periodic monitor module 80 timing scan exist the paging signal of another mobile network.When scanning another mobile network when having the signal paging to enter, if travelling carriage is in running order at current mobile network, then parallel processing is carried out in the signal paging of another mobile network, the data that the needs of the storage in the travelling carriage are responded send to another mobile network.Wherein, if the signal paging is that (mobile communication system is in order to keep and mobile communications for the daily framing signal of base station, the position register information of needed travelling carriage, handover information, roaming communication information etc.), then respond this signal, represent that this travelling carriage is in holding state; If the signal paging is the service signal (as incoming call, short message etc.) of another mobile network, then the data that the needs of the storage in the travelling carriage are responded send, and represent that this travelling carriage is in running order; Perhaps, directly hang up or end the work of current mobile network, be directly switch to the frequency of another mobile network by a hot key.And if travelling carriage is in holding state at current mobile network, then switch to the frequency of another mobile network.
In the present invention, process for the frequency that switches to another mobile network, when current mobile network is in running order, travelling carriage can switch to another mobile network in a fixed time, and in this fixed time, interrupt current mobile network, switch back original mobile network again after finishing the work of this another mobile network, the described fixed time is the gap of current mobile network work.When current mobile network is in holding state, can interrupt current mobile network, switch to the frequency work of another mobile network, finish the work of this another mobile network after, directly in this another mobile network standby.For example, with the GSM/CDMA dual-mode handset is example, suppose that the active user just receives calls in the GSM net, and this moment, the periodic monitor module monitors had the signal paging to the CDMA net, if this signal is basic daily positioning paging, then can not cut off the conversation of this GSM net, and the transmitter module that startup CDMA nets in a fixed time, response has the exchange of the response of this travelling carriage current location information to mobile communication system, switch back this GSM net then and proceed conversation, wherein the process of this startup CDMA net transmitter module and response can be carried out in the middle time slot of the received signal that this GSM nets, in order to avoid cause the interference and the interruption of conversation in the GSM net; If this signal is service signals such as incoming call, then can in the working clearance that these GSM net voice transmit, start the transmitter module of CDMA net, the corresponding response data of storage in advance in the travelling carriage is sent, represent that this travelling carriage is in running order, as select to send echo messages such as " user are busy " and give switch, and keep this GSM net to proceed conversation; Perhaps, the work of current mobile network can directly be hung up or end to the also predeterminable important caller ID of user when incoming call is one of this important caller ID, by a hot key, be directly switch to the frequency of CDMA net, connecting incoming call; Perhaps, can also give information of user, and whether carry out that network switches and connecting incoming call is still ignored this incoming call and continued the original conversation of maintenance by user's decision by travelling carriage.
Equally, be example with the GSM/CDMA dual-mode handset, in the present invention, this periodic monitor module can be interrupted the scanning of carrying out signal in the time slot in the work of the signal reception/emission that GSM/CDMA nets, and interrupts with the work of avoiding current mobile network.
With the GSM/CDMA dual-mode handset is example, because it can support GSM and these two network communications technologys of CDMA simultaneously, thereby can make the user between GSM and CDMA, realize freely switching, thereby avoid problems such as call drop, conversation difficulty and lower tone in the past effectively, only use the conversation of GSM net convenient than before.In the area that some cellphone subscribers relatively concentrate, especially suitable use dual-mode handset, because dual-mode handset can switch between GSM network and cdma network neatly, can remain under some networks conversation does not interrupt, and receive the signal of handling another network simultaneously, with the signal synthesis stack that receives, the signal of different frequency is filtered then, outstanding voice signal is enjoyed thereby obtain high-quality voice.In addition, dual-mode handset adopts broadband technology, multiple functions such as support call transfer, Call Waiting, tripartite talk, caller ID display, short message, voice mail, automatic roaming.
Because the GSM/CDMA dual-mode handset can be operated among the network of two different technologies simultaneously, so dual-mode handset has the characteristics of these two kinds of network technologies undoubtedly.Say that from technical standpoint therefore the GSM network can bring the good speech quality and the covering of communicating by letter because the frequency range height makes that the signal penetration capacity is strong in built-up complex environment; And cdma network, power system capacity is big especially, and same frequency resource, the power system capacity of CDMA net can be 8～10 times of the simulation net, 3～4 times of the GSM net.The GSM net will cover the whole city, Beijing, approximately need set up the base station more than 300, and the base station that CDMA only need build about 80 can reach this purpose, has saved limited frequency resource.The distinctive wideband transmit means of CDMA have extremely strong antijamming capability, and are applicable to leave high speed data transfer business etc. on mobile phone.The appearance of dual-mode handset, for the user, impression will be the darkest undoubtedly, to be again most realistic simultaneously, because use dual-mode handset, by the roaming of GSM/CDMA network, the call drop phenomenon will significantly reduce, throw into and get, can obtain all advantages of two kinds of network technologies simultaneously, so dual-mode handset can guarantee that freely 160 several countries communicate the cellphone subscriber in five continents free more.
But, for travelling carriage of the present invention, if having the emission signal frequency of the received signal frequency of certain mobile network and another mobile network between two mobile networks is separated by under the bigger situation, the problem that can not exist signal to disturb, if and the emission signal frequency that has the received signal frequency of certain mobile network and another mobile network between two mobile networks is separated by under the nearer situation, receive frequency as present CDMA net is about 880MHz, the transmission frequency of GSM net then is about 890MHz, differ less between the two, if the user of dual-mode handset just sends signal in the GSM net, and CDMA nets when wanting the positional information of this dual-mode handset of paging just, cause this moment the signal between the transceiver to disturb easily, cause the paging of cdma system possibility less than mobile phone, therefore, in the present invention, in order to address the above problem, in this travelling carriage, also be provided with frequency filtering module 70---be dedicated diplexer, under the receive frequency of the signal tranmitting frequency of a mobile network and another one mobile network differs less situation, two frequencies are carried out bandpass filtering treatment, the tranmitting frequency of this mobile network and the receive frequency of another mobile network are not disturbed mutually.
Below in conjunction with accompanying drawing, be equipped with and freedom between the GSM of mobile network A standard and CDMA standard, switch the bimodulus card of communication with a draw-in groove, the travelling carriage of single mode card that another draw-in groove is equipped with the mobile network B of another GSM standard is an example, describes the present invention.
As shown in Figure 1, in the time of mobile platform started, this travelling carriage is in holding state, and promptly A, B net is simultaneously online.At this moment, the frequency monitoring module of this travelling carriage is monitored the GSM signal that GSM signal, CDMA signal and the B that nets A nets simultaneously.Have phone to squeeze into GSM number that supposes to listen among the net A, then the GSM standard that switches to net A by handover module is carried out voice call, and this periodic monitor module is monitored net A, net B simultaneously.Not high or when other bad communication phenomenons occurring when the communication quality of GSM standard of net A, can switch in the CDMA standard of net A and proceed conversation, and remain conversation constantly.When this periodic monitor module monitors to net B when paging signal is arranged, as this paging signal is basic daily framing signal, then this travelling carriage can start the transmitter module of net B in the gap that voice signal receives, carry out location registers for the exchange of mobile communication system by transmitter module response locating information, and listen original phone among the net A in the follow-up continued access of end; As this paging signal is service signal, such as being phone or short message, then this travelling carriage can have following several selection: the one, and service signals such as plain old telephone or short message, this moment, travelling carriage can start the transmitter module of net B in the gap that voice signal receives, select suitable data message to respond by transmitter module, as the information of selecting " user is busy " or unlatching " Call Waiting " function or the like to the other side; The 2nd, important phone, the user can set in advance the number of this important phone, and this moment, travelling carriage can directly cut off and the getting in touch of this net A, and netted B and switch to, and directly answered this incoming call, and behind the talk-through, this travelling carriage can directly be in holding state in this net B; The 3rd, give information of user by travelling carriage, and whether carry out that network switches and connecting incoming call is still ignored this incoming call and continued the original conversation of maintenance by user's decision.
