Apparatus embodiments two:
As shown in Figure 5, the present embodiment provides a kind of terminal, and described terminal comprises the first network module 210 and the 2nd network module 220;
Described first network module is any the first network module described in technical scheme of apparatus embodiments one. Described terminal can treat terminal for various types of multimode list; Terminal described in the present embodiment, terminal is treated relative to existing multimode list, can in the redirected process of the first network and the 2nd network, can keep fast as far as possible and be redirected to the first network, to obtain the network service of more high-quality, reduce the response time being redirected, it is to increase user uses satisfactory degree.
Below in conjunction with above-mentioned any embodiment, it is provided that two concrete examples.
Example one
It is applied in the terminal comprising 4G module, 2G/3G module in this example; Wherein, described 4G module is the first network module in above-described embodiment; Described 2G/3G module is the 2nd network module in above-described embodiment. What be equivalent to above-mentioned first network in this example is 4G network; What be equivalent to above-mentioned 2nd network is 2G/3G network.
Described reorientation method comprises the following steps:
Step S101:4G module sends expansion service request to network side; Usual described network side extended theorem request is that the network break-in network element such as the base station by network side or evolved base station receives. The expansion service request of initiating to network side that described extended theorem request may be the CSFB that causes of the phonetic dialing based on user and be formed.
Step S102:4G module receives the wireless connections release message that network side is replied described expansion service request and sent.
Step S103:4G module sends the message being redirected to 2G/3G to 2G/3G module; The message of the described 2G/3G of being redirected to is equivalent to the first redirection information in above-described embodiment.
Step S104:2G/3G module carries out the selection of 2G/3G community; If in cell selection procedure, user hangs up the telephone, and interrupts phonetic dialing. In the prior art, even if 2G/3G module detects the operation that user hangs up the telephone, also can still continue the selection of 2G/3G, resident carry out location area updating to 2G/3G community after, return the step of 4G network starting 4G module; And in the present embodiment, then directly enter step S105.
Step S105:2G/3G modules interrupts 2G/3G community is selected.
Step S106:2G/3G sends to 4G network and starts 4G module, returns the information of 4G network; This information is equivalent to the 2nd redirection information in above-described embodiment.
Owing to 4G network module is after receiving wireless connections release message, it does not have be directly switch to deactivation status as prior art, but remain on state of activation, when after the message receiving described step S106, it is determined that continue to remain on 4G network. If before the information that receiving step S106 sends, the base station of the first community of described 4G network module and 4G network connects, and makes terminal reside in the first community; Then after receiving the message that step S106 sends, continue maintenance and reside in described first community. Hang up the telephone user like this, when causing CSFB to interrupt, when 2G/3G module triggering 4G module is redirected to 4G network, 4G module need not search for 4G network more again, to described to 4G network selecting community is resident and the operation such as tracing section updating, just can directly use 4G network, enjoy the service of 4G network, for user, terminal there is no time delay by 2G/3G network redirection to 4G network, thus response delay is little. 2G/3G network substantially now inreal for terminal itself is to the switching of 4G network, and the mutual signaling of terminal and network side is few.
Example two:
This example is the further improvement on the basis of a upper example, and this example comprises the following steps:
Step S101:4G module sends expansion service request to network side.
Step S102:4G module receives the wireless connections release message that network side is replied described expansion service request and sent.
Step S103:4G module sends the message being redirected to 2G/3G to 2G/3G module.
Step S104:2G/3G module carries out the selection of 2G/3G community. The operation that user does not hang up the telephone in the process, then enter step S201.
Step S201:2G/3G module notice 4G module, resident to 2G/3G community; This community is the community that step S104 selects.
Step S202:4G module preserves the cell information of the resident 4G network cell of current terminal; Described cell information can comprise the frequency point information of this community.
Step S203:4G module activation 2G/3G module. 4G module activation 2G/3G module or 2G/3G module activation 4G module can be equivalent to described first heavy data or signal to information or the 2nd redirection information realize by sending in this application. After this step, described 4G network module is also switched to deactivation status, disconnects the connection with 4G network, carries out and the connection of 2G/3G network for interrupting to vacate the parts such as antenna.
Step S204:2G/3G module carries out location area updating; If now user hangs up the telephone, stop dialing, then CSFB stops. In the prior art now, location area updating can be proceeded, it is determined that resident arrived 2G/3G network after, be redirected return 4G network; And in the present embodiment, then directly enter step S205.
Step S205:2G/3G modules interrupts location area updating, namely closed position district upgrades.
Step S206:2G/3G module activation 4G module, returns 4G network.
Step S207:4G module, according to the cell information preserved before, is attempted resident to described community. The scope of activity of usual user in the time range of dialing is limited, very big probability also may stop in the scope covered in original 4G network cell, when there is not cataclysm in wireless environment, even if re-starting 4G web search or community selection, the probability that the community that satisfies condition can be provided very big be still before community, therefore attempt resident according to cell information resident before. If can not assistant to reselect 4G network cell resident.
Step S208: resident after 4G network, described 4G module also needs to carry out tracing section updating.
