Description
Technical field
The present invention relates to the changing method of multimode subscriber equipment in the wireless communication system, particularly in the wireless communication system multimode subscriber equipment according to the changing method of Added Business.
Background technology
Along with development of human society, the requirement of mobile communication technology is improved constantly and variation, therefore occurred first in succession to 3G (Third Generation) Moblie.
This causes existing different wireless access technologys at present moving communicating field, also has the wireless network based on different technologies thus.For instance, these wireless networks based on different technologies include, but are not limited to global system for mobile communications (the Global System formobile Communication in the second generation mobile communication, be called for short " GSM ") and code division multiple access (Code Division MultipleAccess, be called for short " CDMA "), Wideband Code Division Multiple Access (WCDMA) in the 3G (Third Generation) Moblie (WidebandCode Division Multiple Access, be called for short " WCDMA "), TD SDMA (TimeDivision Synchronous Code Division Multiple Access, be called for short " TD-SCDMA ") and CDMA 2000 (Code Division Multiple Access 2000 is called for short " CDMA2000 ") or the like.
Wherein, because based on different technology, therefore different wireless networks provides the ability of wireless traffic uneven.3-G (Generation Three mobile communication system) such as WCDMA provides the ability of wireless traffic just to be better than the second generation mobile communication system such as GSM greatly.For example WCDMA can provide high-speed data service, but GSM does not just accomplish.
On the other hand, in order to satisfy the requirement of the wireless traffic that different networks provides, subscriber equipment (User Equipment in recent years, abbreviation " UE ") ability also becomes more and more stronger along with the continuous new business of releasing of wireless network, it can support two or more wireless traffics simultaneously, for example carries out data service communication etc. simultaneously in conversation.UE can be a multimode also in addition, that is to say to support at least two types communication network simultaneously, for example can support GSM or WCDMA simultaneously.The benefit of this multimode UE is to make full use of conventional network resources, for example original mobile operator has set up a large amount of GSM networks, carried out the upgrading of WCDMA network afterwards, but because the restriction of cost, time or demand side, in a stage, can't realize all regions is all covered WCDMA, if with the UE that only supports WCDMA then may all can't carry out at the most basic phonetic function of some Local Force Company.
Below with reference to Fig. 1, describe in the prior art, when being in UE under the talking state and need increasing a certain wireless traffic newly, the processing mode of current network.
As shown in Figure 1, when the UE under being in talking state need increase a certain wireless traffic (for example high-speed data service) newly, in step 110, this UE initiated " Added Business request information in the sub-district of current maintenance conversation.
After this enter step 120, the response of current wireless network is above-mentioned, and " the Added Business request information checks whether can provide this business.Here only, this zone checks for providing the wireless network that the sub-district was subordinate to of service to current.If judge that current network does not possess the ability that Added Business is provided, then enter step 140, refusal Added Business, i.e. Added Business failure.If judging to provide Added Business, then enter step 130, increase this Added Business.
For example, for a WCDMA/GSM bimodulus UE, when being in the GSM Internet phone-calling, if this UE sends the high-speed data service request to network, then the GSM network judges whether to possess the ability that this Added Business is provided, because the GSM network can't provide this Added Business, therefore refuses the request of UE.
In actual applications, there is following problem in such scheme: the ability that can't make full use of the wireless network that other sub-districts were subordinate to of overlay area.
Cause the main cause of this situation to be, do not trigger the mechanism of switching at present in the industry according to the newly-increased business of multimode UE.Specifically, in above-mentioned example, the wireless network that other sub-districts that might current overlay area are subordinate to, as the WCDMA network, can support talk business and high-speed data service simultaneously, but according to the processing method of prior art, can satisfy the network that is used for business demand even current overlay area exists, because WCDMA/GSM bimodulus UE is in the talking state of GSM network and can't transfers to the WCDMA network.The network that causing the user region to exist thus can provide Added Business still can't obtain the problem of this Added Business.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of multimode subscriber equipment is initiated switching according to Added Business method, make it possible to utilize more fully the ability of the multiple wireless network of overlay area, when multimode UE initiates new business, can in time switch to and have the wireless network that new business and current business ability are provided simultaneously.
In order to solve the problems of the technologies described above, the invention provides a kind of multimode subscriber equipment method that initiation is switched according to Added Business, comprise following steps:
When A initiates the request of described Added Business when described multimode subscriber equipment, judge the ability that whether current area possesses provides described Added Business,, otherwise enter step B if then enter step D;
The described multimode subscriber equipment of B judges that whether other sub-districts that cover described multimode subscriber equipment current location possess the ability that described Added Business is provided, if then enter step C, otherwise return the Added Business failure information;
The described multimode subscriber equipment of C sends handoff request message to other sub-districts that possess the ability that described Added Business is provided, and judges whether handover success, if then enter step D, otherwise returns the Added Business failure information;
The described multimode subscriber equipment of D sends the request message of described Added Business, and the business of setting up described Added Business connects.
Wherein, the type of described sub-district is any one in global system for mobile communications, code division multiple access system, broadband CDMA system, code division multiple access CDMA2000 system or the TDS-CDMA system.
Described multimode subscriber equipment is supported at least two kinds in global system for mobile communications, code division multiple access system, broadband CDMA system, code division multiple access CDMA2000 system, the TDS-CDMA system.
When described multimode subscriber equipment was initiated the request of described Added Business, described multimode subscriber equipment was carrying out at least a other business.
Described business is speech business or high-speed data service.
By relatively finding, technical scheme difference with the prior art of the present invention is, when multimode UE is carrying out at least a business, multimode UE is according to newly-increased business, situation in conjunction with local subzone network, initiatively select proper cell to initiate handoff request, initiate the corresponding business request behind the handover success again.
Difference on this technical scheme, brought comparatively significantly beneficial effect, be that multimode UE is before network is initiated the Added Business request, judge earlier whether current area can provide multimode UE newly-increased business, if current area can not provide this business, then can not send service request, greatly reduce the processing load of current network to current area.After switch the sub-district of triggering according to business, promptly initiate the Added Business request to network, set up professional.Whole process shields the user, user's sensation is consistent with initiating Added Business in current area, the user just need not be concerned about whether the sub-district of mobile phone current talking can provide the business of being initiated like this, and is searched for automatically by mobile phone, brings great convenience to the user.

Fig. 2 is multimode UE according to an embodiment of the invention initiates switching according to Added Business a method flow diagram.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, when multimode UE just converses, and need to initiate Added Business in the more weak GSM network of ability, for example during high-speed data service, enter step 210.
In step 210, multimode UE initiates the Added Business request message to network, and this Added Business can be a high-speed data service etc.
After this enter step 220, multimode UE judges whether the current sub-district of communication that provides possesses the ability that above-mentioned Added Business is provided.If judging to provide above-mentioned Added Business, then enter step 270, otherwise enter step 230.
In step 230, can not provide multimode UE the Added Business of needs because step 220 is provided by the current sub-district of communication that provides, in this step, multimode UE further judges whether other sub-districts of current covering multimode UE region possess the ability that Added Business is provided.
Specifically, multimode UE searches for other sub-districts of current covering multimode UE region, judges the business whether wireless network that these sub-districts are subordinate to can provide multimode UE to increase newly.If do not have to provide other sub-districts of Added Business, then enter step 240; Have the sub-district of the Added Business that multimode UE needs can be provided if find this overlay area, for example the WCDMA sub-district then enters step 250.
In step 240, provide multimode UE the ability of required Added Business owing to judging that in step 230 other sub-districts that cover multimode UE region do not possess, therefore in this step, multimode UE returns the Added Business failure information to the user.For example the position at multimode UE place only is coated with the GSM network, and this network does not provide multimode UE newly-increased high-speed data service, so the Added Business failure, and multi mode terminal informs that by liquid crystal display screen the user can't use this business.So far flow process finishes.
In step 250, owing to judge that in step 230 there is the Wi-Fi that Added Business can be provided in the zone at multimode UE place, therefore multimode UE sends handoff request message to network in this step.That sub-district that Added Business can be provided is promptly judged by multimode UE in the purpose sub-district of switching, and after this enters step 260.
In step 260, in cell switch process, owing to reason such as the purpose cell capacity is limited, cause not all switching to realize smoothly, therefore in this step, multimode UE judges according to the related news of receiving from the network side of purpose sub-district whether the sub-district switching is successful, if, then enter step 270, otherwise enter step 240.
In step 270, finish after the sub-district switches, multimode UE provides the wireless network of required Added Business ability to set up talk business with possessing, and sends the Added Business request message to this network.
After this enter step 280, network response Added Business request message is set up this newly-increased business and is connected, and so far flow process finishes.Thus, the connection of the Added Business that can't realize in the prior art is achieved by switching to the wireless network that possesses the Added Business ability in the present invention.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
