Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of call method for building up, device, terminal and computer-readable
Storage medium.
Background technology
Because LTE (Long Term Evolution, Long Term Evolution) network only supports data exchange service (i.e. PS in itself
Only), therefore, want to carry out voice call under LTE network, it is necessary to corresponding solution.For the above situation, existing skill
In art, mainly there are three kinds of solutions, be respectively：
(1) SGLTE (Simultaneous GSM and LTE), i.e., conversed respectively in the presence of two groups of network signals simultaneously
And online.Preferably, conversed using 2G networks, surfed the Net using 4G networks.
(2) CSFB (Circuit Switched Fallback, circuit domain dropping), i.e., in call, the signal meeting of terminal
2G signals are fallen back to from 4G signals.
(3) Volte (Voice over LTE, the speech business based on IMS) 4G (the 4th Generation
Mobile communication technology, fourth generation mobile communication technology) voice technology.It is i.e. independent in the lte networks
Divide a part of bandwidth to be used to voice being converted into data, so as to be directly realized by call under 4G networks.This mode Call Waiting
Time is shorter, tonequality is more preferable, video calling is apparent, and under contrast, this scheme is better than CSFB and SGLTE.But current
The 4G network coverages are not comprehensive enough, and Volte can not effectively play a role.In the case where running into no 4G signals, phone will be unable to
Put through.
In summary, most operator's selection covers insufficient feelings as LTE network using CSFB schemes at present
Transition scheme under condition.But by test, during making to switch from 4G networks to 2G networks, it occur frequently that due to small
Area or frequency access failure and the situation for causing call setup failure, and it is time-consuming longer.
The content of the invention
In view of the foregoing, it is necessary to which a kind of call method for building up, device, terminal and computer-readable storage medium are provided
Matter, the time of cell searching can be saved during CSFB, lift the call experience of user.
One kind call method for building up, methods described include：
It is pre- by described first when terminal can not access the first predetermined cell and cause the call connection failure with callee
Determine cell addition first and forbid cell list；
Skipping described first forbids the cell in cell list to carry out cell searching；
After the first object cell for meeting preparatory condition is searched, the first object cell is accessed, passes through described
One Target cell carries out call re-establishment to the callee.
It is described to skip described first and forbid cell in cell list to carry out cell searching according to the preferred embodiment of the present invention
Including：
Forbid one or more cell in cell list to be stored in described first forbidding cell to arrange when described first
Duration in table is less than or equal to preset duration, and the current signal strength and initial signal of one or more of cells
When the difference of intensity is less than or equal to preset value, skips one or more of cells and carry out cell searching.
According to the preferred embodiment of the present invention, methods described also includes：
Forbid one or more cell in cell list to be stored in described first forbidding cell to arrange when described first
Duration in table is more than the preset duration, and the current signal strength and initial signal intensity of one or more of cells
Difference when being more than the preset value, cell list is forbidden into one or more of cells removal described first.
One kind call method for building up, methods described include：
It is pre- by described second when terminal can not access the second predetermined cell and cause the call connection failure with calling party
Determine cell addition second and forbid cell list；
Skipping described second forbids the cell in cell list to carry out cell searching；
After the second Target cell for meeting preparatory condition is searched, judge the position area of second Target cell with it is pre-
If whether position area is consistent；
When the position area of second Target cell is consistent with predeterminated position area, second Target cell is accessed, is led to
Cross second Target cell and call re-establishment is carried out to the calling party.
According to the preferred embodiment of the present invention, methods described also includes：
When the position area of second Target cell is inconsistent with predeterminated position area, it is small that second target is not accessed
Area, abandon carrying out call re-establishment to the calling party.
Device is established in one kind call, and described device includes：
Module is added, causes the call connection failure with callee for the first predetermined cell can not to be accessed when terminal
When, cell list is forbidden into first predetermined cell addition first；
Search module, the cell in cell list is forbidden to carry out cell searching for skipping described first；
Call re-establishment module, for after the first object cell for meeting preparatory condition is searched, accessing first mesh
Cell is marked, call re-establishment is carried out to the callee by the first object cell.
According to the preferred embodiment of the present invention, the search module is specifically used for：
Forbid one or more cell in cell list to be stored in described first forbidding cell to arrange when described first
Duration in table is less than or equal to preset duration, and the current signal strength and initial signal of one or more of cells
When the difference of intensity is less than or equal to preset value, skips one or more of cells and carry out cell searching；
Described device also includes：
Module is removed, for forbidding one or more cell in cell list to be stored in described the when described first
One forbids the duration in cell list to be more than the preset duration, and the current signal strength of one or more of cells with
When the difference of initial signal intensity is more than the preset value, cell is forbidden into one or more of cells removal described first
List.
Device is established in one kind call, and described device includes：
Module is added, causes the call connection failure with calling party for the second predetermined cell can not to be accessed when terminal
When, cell list is forbidden into second predetermined cell addition second；
Search module, the cell in cell list is forbidden to carry out cell searching for skipping described second；
Judge module, for after the second Target cell for meeting preparatory condition is searched, judging that second target is small
Whether the position area in area and predeterminated position area are consistent；
Call re-establishment module, for when the position area of second Target cell is consistent with predeterminated position area, accessing institute
The second Target cell is stated, call re-establishment is carried out to the calling party by second Target cell.
A kind of terminal, the terminal include processor, and the processor is used to perform the computer journey stored in memory
The step of call method for building up is realized during sequence.
A kind of computer-readable recording medium, is stored thereon with computer program, and the computer program is held by processor
The step of call method for building up is realized during row.
As can be seen from the above technical solutions, the present invention causes and callee when terminal can not access the first predetermined cell
Call connection failure when, first predetermined cell addition first is forbidden into cell list；Skip described first and forbid cell
Cell in list carries out cell searching；After the first object cell for meeting preparatory condition is searched, first mesh is accessed
Cell is marked, call re-establishment is carried out to the callee by the first object cell.Can be in CSFB process using the present invention
The middle time for saving cell searching, lift the call experience of user.
