Description
Technical field
The present invention relates to communication technical field, more particularly, to a kind of wireless communication terminal and its method for switching network.
Background technology
Due to the broad development of current 3G wireless technologys so that the business based on radio communication is a lot, due to wireless technology
Towards broadband evolution so that being formerly only available the business in wire communication can transplant into radio communication, but due to
The necessarily long-term co-existence of the reason for network design, 2G and 3G network.
In networking and optimization process, 2G technologies are optimized because settling time is grown, and all exist in many areas
2G signals are better than 3G signals, because business need not be concerned about actual access technology in itself, in general using upper not assorted
Problem, as common network browsing, voice call need bandwidth it is limited, it is little in 2G and 3G application difference, but due to
The fast development of wireless broad band technology, it is right as visual telephone, this kind of business very high to bandwidth requirement of HD video demand (telecommunication) service
The requirement of access technology is just very high, because the advantage of radio communication is the limitation that eliminates region, user can be made in office
Where point enjoys a trip to network, but user is using some drawbacks being present, due to current Terminal Design be using network side it is leading,
Wireless terminal belongs to subordinate status, and user, can be due to geographical environment, the network coverage when using the business very high to bandwidth requirement
Etc. reason, allow user to be switched under 2G patterns, but the carrying of 2G patterns is difficult to support the application of above-mentioned business.It is existing at present
Technology is whole in switching control to be dominated by network, and UE is passive execution, is better than the situation of 3G signals in 2G signals
Under, wireless data terminal meeting reported event informing network, network can issue switching command, allow wireless data terminal to be moved from 3G network
Move on on 2G networks, such that smooth can not be run similar to business as PPS, cause user to use some industry
Business.
The content of the invention
The present invention seeks to overcome unreasonable switching present in prior art to cause service disconnection or business to flow
Smooth the problem of carrying out and defect, there is provided a kind of wireless communication terminal and its method for switching network.
To achieve the above object, the present invention proposes a kind of wireless communication terminal, and the wireless communication terminal includes wireless money
Source control module, Application inspection module, subscriber identification module；

The current situation of the characteristic and network of the Application inspection module check current business, so as to judge whether by
Terminal is switched to other networks from existing network；
The log-on message and the network information of the subscriber identification module storage wireless terminal.
Further, the network switching refers to the switching between networks with different systems.
Further, the characteristic of the Application inspection module check business and the current situation of network, when detecting
When network condition is deteriorated at present, judge whether the ongoing business of wireless communication terminal can be entered in other networks detected
OK, if can not carry out, wireless communication terminal is prevented to report other detected network informations to network.
Further, judge whether the ongoing business of wireless communication terminal can be carried out in other networks, if can enter
OK, then wireless communication terminal is allowed to report other detected network informations to network.
Further, when current network condition is deteriorated, wireless heterogeneous networks module is by measurement report message by EVENT
2D reporting events networks, the network condition for telling network current have been deteriorated, and current network sends physical link and is reconfigured to nothing
Line resource controlled block.
The present invention also proposes a kind of method for switching network, and for wireless communication terminal handover network, the radio communication is whole
The current situation of the characteristic and network of the Application inspection module check wireless communication terminal current business at end, if current net
Network situation is deteriorated, then whether other networks for judging to detect can carry out wireless communication terminal current business, if can not carry out,
Then wireless communication terminal is prevented to report other detected network informations to network.
Further, the network switching refers to the switching between networks with different systems.
Further, it is described to judge whether the ongoing business of wireless communication terminal be carried out in other networks, if
It can carry out, then allow wireless communication terminal to report other detected network informations to network.
Further, when current network condition is deteriorated, wireless heterogeneous networks module is by measurement report message by EVENT
2D reporting events networks, the network condition for telling network current have been deteriorated, and current network sends physical link and is reconfigured to nothing
Line resource controlled block.
In summary, had the advantages that using the present invention：
Compared with prior art, technical solution of the present invention, which changes wireless terminal, can only passively perform the office of network side requirement
Limit, actively the network of switching can be adjusted correspondingly according to the requirement of business, improve the usage experience of user, simultaneously
Reduce the signalling loads of network.

Embodiment
Switching can make wireless data terminal more possess flexibility between carrying out network system based on type of service, rather than
The instruction that simple execution network simply issues.Thus it is avoided that network side configures unnecessary switching command and caused in business
Disconnected or business is not smooth.
Institute's technical scheme of the present invention overcomes unreasonable switching present in prior art to cause service disconnection or business not
Energy smooth the problem of carrying out and defect, there is provided a kind of method and apparatus for based on type of service between network system switch.
Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, in following examples
In, 2G networks of the present invention are by taking GSM/EDGE cordless communication networks as an example, and 3G network is by taking UMTS Terrestrial radio access network as an example.When
So, the technical scheme is that based on different business is distinguished, more flexible removes handover network, and therefore, technical solution of the present invention is simultaneously
Be not limited to the switchings of other standard networks such as the switching of 2G networks and 3G network, 2G, 3G and LTE also the scope of the present invention it
It is interior.
It refer to shown in Fig. 1, be wireless communication terminal composition schematic diagram of the embodiment of the present invention, it includes wireless heterogeneous networks
Module, Application inspection module, user identification module.Wireless communication terminal is in UMTS Terrestrial radio access network and GSM/
