Specific embodiment
In order to which the purpose of the present invention, technical solution and advantage is more clearly understood, with reference to the accompanying drawings and embodiments,
The present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention,
Do not limit the present invention.
As depicted in figs. 1 and 2, the method for switching network based on circuit domain dropping the following steps are included:
S201: the redirection for receiving base station is ordered to obtain communication frequency point.
Specifically, network carries out FR process after end of conversation, is issued to terminal device and redirect order (RRC
Connection Release).The communication frequency point that order carried terminal equipment can return to is redirected, guiding terminal equipment is used for
Return to LTE network.
S203: it is requested on communication frequency point to base station initiating updating of tracking area.
Tracking area is to apply corresponding band of position concept in EPS system, and this band of position is known as tracking area,
And EPS is then one based on existing radio paging system and the Internet computer network communication technology, and organically will be global
Network information communications processing exhales the global bilateral network in conjunction with business processing flow to lead paging system with domestic wirelessly lead.?
After end of conversation, initiating updating of tracking area is requested to update position area on redirecting the communication frequency point obtained.
S205: whether judgement receives the response requested tracing section updating base station within a preset time.
It should be understood that starting timer after time initiating updating of tracking area is requested, asked to when secondary tracking area updates
The sending time asked carries out timing.It should be understood that before carrying out timing to the sending time for tracking request when secondary tracking area,
To also processing be zeroed out to the sending time of last tracking area tracking request.
If receiving the response that tracing section updating is requested in base station within a preset time, S206 is thened follow the steps: according to logical
Believe frequency handover to LTE network.
If it is not, not receiving the response requested tracing section updating base station within a preset time, then follow the steps:
S207: a frequency point is obtained from history LTE frequency point, and communication frequency point is updated to the frequency point got.
When communicating the dtr signal of frequency point, the response that tracing section updating is requested in base station can not receive.If in preset time
It does not receive response inside, then obtains a frequency point from history frequency point, and communication frequency point is updated to the frequency point got.
Specifically, history LTE frequency point is the LTE frequency point that terminal device was resident, it is stored in acq_db file.From history
The frequency point that the terminal device registered is obtained in LTE frequency point and communication frequency point is updated to the frequency point got.
After step S207, S203 is returned to step, initiates tracking area more to base station on the communication frequency point of update
New request, and judge that whether receive base station within a preset time requests to tracing section updating, i.e. whether TAU request succeeds, if
It is no, then continue the communication frequency point updated from history frequency point, until TAU success, is switched to LTE network.
The method for switching network based on circuit domain circuit is not received within a preset time in the dtr signal of communication frequency point
When updating the response of request to more new district to base station, the communication frequency point of update is obtained from history LTE frequency point, and in the update
Continue to be requested to base station initiating updating of tracking area until TAU success, according to communication frequency handover to LTE net on communication frequency point
Network.This method can be protected when the communication frequency point signal for redirecting order acquisition is weaker, can be obtained more from history frequency point
New communication frequency point is switched to LTE network even if mobile phone can also initiate TAU process in signal weaker area.
In another embodiment, before step S201 further include:
S101: the starting call instruction of user is responded, carries out voice communication from LTE network using circuit domain circuit type.
Call instruction is specially the operation made a phone call that user carries out on the terminal device.
Circuit domain dropping (Circuit Switched Fallback, CSFB) refers to that terminal device resides in LTE network,
Fall back to the domain CS of 2G/3G network again when needing to complete voice service.The use of CSFB has precondition, only in E-
UTRAN's and UTRAN/GERAN is overlapping covered, and when user has the function of CSFB, could use circuit domain dropping.
S103: the end call instruction of user is responded.
Terminating call instruction is specially the operation hung up the telephone that user carries out on the terminal device.Terminate in voice communication
Afterwards, terminal device needs are important switches back into former LTE network.
In another embodiment, step S209 includes:
S2091: registered history LTE frequency point is obtained.
Specifically, history LTE frequency point is the LTE frequency point that terminal device was resident, it is stored in acq_db file.
S2092: one available frequency point of distribution.
Specifically, obtaining available frequency point from acq_db file.
S2093: frequency point will be communicated and be updated to the frequency point distributed.
In other specific embodiments, step S2092 is specifically included: from history LTE frequency point, distributing residence time
Apart from current time, the frequency point of nearest and unassigned mistake is as available frequency point.
Specifically, the frequency point that history LTE frequency point is resident when residing in LTE network for the terminal device, from history LTE frequency
In point, the frequency point of residence time nearest and unassigned mistake apart from current time is distributed as available frequency point, by the available frequency
Point is as the communication frequency point updated.Since assigned frequency point is nearest apart from current time, that is, the frequency point is that terminal is resident recently
The frequency point crossed, the success rate that TAU process is initiated on the frequency point is higher, can be switched to LTE network faster.
In another embodiment, after step s 103, it further comprises the steps of:
S105: whether the position where detection terminal changes.
If so, the position where detecting terminal changes, then follow the steps: S109: sending present bit to base station
Confidence breath, and execute step S201: the redirection for receiving base station is ordered to obtain communication frequency point.
If it is not, the position i.e. where detection terminal does not change, S107 is thened follow the steps: before circuit domain dropping
Frequency handover is communicated to LTE network.
Under normal conditions, if terminal user does not converse in moving process, led to for example, being sitting on office chair
Words rise and exhale and when on-hook in identical position, and usual frequency point does not change, that is, rise be also at when exhaling with on-hook it is identical
LTE frequency point.It in this case, can be according to the communication frequency handover before circuit domain dropping to LTE network.
If terminal user converses in moving process, for example, converse when driving, rise when exhaling with on-hook
In different positions, caused to exhale due to change in location with when on-hook in different LTE frequency points, in this case,
Current location information is sent to base station.It after base station receives current location information, is sent to terminal and redirects order, issued and whole
The corresponding communication frequency point in current location is held, and initiating updating of tracking area is requested to be switched to LTE network on the communication frequency point.
It is not changed in terminal location by determining the need for redirecting to whether terminal position changes
In the case of, LTE network is quickly switched to according to the communication frequency point before circuit domain dropping, without redirecting, accelerates end
Hold the speed of handover network.
