Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment technical scheme done and further elaborate.
Embodiment of the method one:
As in figure 2 it is shown, the present embodiment provides a kind of reorientation method, described method is applied in the terminal including first network module and the second mixed-media network modules mixed-media, and described method includes:
Step S110: first network module receives the wireless connections release message that network side sends；Wherein, described first network module is active and described terminal resides in the first community of first network；
Step S120: according to described wireless connections release message, described first network module is switched to deactivation status, makes described terminal disconnect the connection with described first network；
Step S130: send the first redirection information to described second mixed-media network modules mixed-media；Described first redirection information is used for triggering described second mixed-media network modules mixed-media and is redirected to the second network；
Step S140: receive the second redirection information that described second mixed-media network modules mixed-media sends when being redirected to described second network and stopping；
Step S150: store the cell information of described first community；
Step S160: according to described second redirection information and described cell information, be redirected to the first community of described first network；
Wherein, described first network and communication network that described second network is different communication standard.
First network described in the present embodiment is the network that communication standard is higher than the communication standard of described second network, and specifically if described first network can be 4G network, described second network can be 2G/3G network.
Terminal described in the present embodiment can be multimode terminal, it is concrete as forth generation 4G network not only can be used, but also UMTS network and the second filial generation/3rd can be used to treat the terminal of 2G/3G network, and preferred described terminal is for singly treating terminal, namely different time can use the network of different communication standards, but a time point is only capable of using the network of a kind of communication standard, and common terminal specifically can such as i Phone.
Wireless connections release message in step S110, is the connection for triggering described first network module release now first network.
Described step S120 facilitates follow-up second mixed-media network modules mixed-media be connected to described second network, therefore according to described connection release message, deactivation status will be switched to, with the connection of terminal described in fault block Yu described first network.
Described step S130 can pass through to send described first redirection information to described second mixed-media network modules mixed-media, it is possible to activates described second mixed-media network modules mixed-media, and triggers the operation that described second mixed-media network modules mixed-media starts to perform to make terminal be redirected to described second network.
Described step S140 for when terminal fallen after rise by CSFB there is break event in the second network time, described second mixed-media network modules mixed-media can send the second redirection information to described first network module.
Step S150 is the information storing described first community, specifically such as information such as the frequency point information of described first community and cell IDs, described step S150 and step S110 to step S140 does not have certain sequencing, as long as the cell information of described first community can be preserved.In real process, it is preferred to kept the cell information of described first community before performing described step S120, or the problem made mistakes can not be preserved in order to avoid occurring preserving.
First network module in step S160, after receiving the second redirection information, the cell information of the first community preserved before utilization, set up the connection with first network, to be redirected to the first community of described first network.
If electronic equipment is when performing CSFB and carrying out audio call, the time generally carrying out audio call is all shorter；If now user's interrupt the call, usual electronic equipment also can in the geographic range of described first community, if generally it backs within first network, described first community has very big probability to be the optimum subdistrict that described interruption can be resident；If according to existing method, then first described first network module will carry out the search at the first networking, can be resident or adapt to the community of resident first network most being selected by the process of the signals such as level signal, and it is finally resident to first network, and adopt the method described in the present embodiment, the community of the search and first network that no longer carry out described first network selects, but directly with resident first community to described first network of information of the first community of first network.Step S160 specifically can include the frequency point information according to described first community, set up network with the base station of described first community or evolved base station and be connected, thus resident to described first community.
Obviously, when described terminal returns to resident the first community to first network from the second network, the search of first network and the process of the selection of first network community are eliminated, it is clear that reduce the network delay being redirected to first network.The community of search and first network that terminal no longer carries out first network community selects, decrease and the network of first network counts the interaction times of signal or information between equipment (such as base station or evolved base station), thus decrease signaling consumption and the power consumption of described terminal, thus improve the standby time of described terminal.
Described second networking is redirected to described second network and is included: the operation of the selection of the second community, networking and the renewal of lane place.
The described generation being redirected to described second network break event, it may occur however that any time before or after any one stage or above-mentioned two stage in above-mentioned two stage.
Described step S140 comprises the steps that
Receive described second redirection information that described second mixed-media network modules mixed-media sends when selecting the second community to stop；Wherein, described second community is the community that second network coverage is formed.
Described step S140 may also include that
When receiving the location area updating termination that described second mixed-media network modules mixed-media is redirected to described second network, described second redirection information of transmission.
If described terminal is multimode list treats terminal, then time point is only capable of the network foundation set up with a kind of communication standard and is connected, after being generally completed the selection of the second community, the connection that described second mixed-media network modules mixed-media will be set up with described second networking, third before needing the connection discharging the release of described first network module with described first network, usual described first network module can realize discharging described first network by switch to deactivation status and connect.Further, if described second mixed-media network modules mixed-media is selected by community, it is determined that after the second resident community, it will send described switching presence information to described first network module.
Therefore the method described in the present embodiment may also include that and receives the switching presence information that described second mixed-media network modules mixed-media sends after the selection completing the second community.
When implementing, the step that the release of first network module described in described step S120 is connected with described first network can occur after receiving described connection release message, can also be: after receiving described switching presence information, described first network module is switched to deactivation status, makes described terminal disconnect the connection with described first network.
If according to the method, if described second mixed-media network modules mixed-media is carrying out the second community selection termination, then can continue to keep the state of activation of described first network, so that described terminal continues to reside in described first community；Obviously second network redirection to first network again just it is absent from, obviously terminal can be kept when the second community selects, still can enjoy the connection of first network, no longer with being attached first network, obviously further reduce signaling consumption and save terminal energy consumption, user can be made to feel after interrupt call, it is possible to enjoy the network service of first network immediately, thus improve user's user satisfaction simultaneously.
It should be noted that: how described first network module specifically distinguishes described second redirection information is that the break event selected because of the second community at the second mixed-media network modules mixed-media sends, and is also because the break event transmission of location area updating.Whether described first network module according to receiving before this described switching presence information can judge, receiving described switching presence information just it is believed that the second redirection information is the second mixed-media network modules mixed-media is based on the break event of location area updating and sends if having before this, being otherwise regarded as what the break event selected based on the second community sent.
In addition, in the present embodiment, described second redirection information is that described second mixed-media network modules mixed-media sends immediately after redirection the second network break event being detected, as detected, user sends when stopping phonetic dialing immediately, even if but not being still redirected to the second network after break event being detected in prior art and completing the second redirection information of sending after location area updating；Thus it not be used in and resident after the second network, return again to first network, so can improve the speed returning to first network at this.
