Description

Method and device for switching EVDO network to LTE network and mobile terminal
The application is a divisional application of an invention patent application with the application date of 2017, 03 and 31, and the invention name of 'method, device and mobile terminal for switching an EVDO network to an LTE network', and the application number of 201710211147.9.
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for switching an EVDO network to an LTE network, and a mobile terminal.
Background
EVDO (EV-DO) is an abbreviation for three words: evolution, data Only, which is called as: CDMA2000 xEV-DO, or "Data Only", IS a stage of a path for CDMA2000 1x evolution (3G) that enables operators to achieve forward Data transmission rates up to 2.4Mbps using a CDMA carrier frequency of the same bandwidth as IS-95 or CDMA 2000.
When establishing a data connection in the existing EVDO network mode, the terminal starts a D2L (EVDO to LTE) timer, and the default value of the D2L timer is 60 seconds. Before the D2L timer is overtime, if data transmission continues, even if an LTE network exists, the terminal cannot automatically reselect the LTE until the D2L timer is overtime. The timer is cleared if the data transmission is stopped before the timer times out.
In addition to the above-described automatically initiated network handover, there are also situations in which a user manually switches networks during data transmission: if the user manually switches the EVDO network to the LTE network before the D2L timer expires, the user needs to wait until the D2L timer expires to initiate the switching, and the time is up to 60 seconds. If the user switches the network after the D2L timer is overtime, the terminal can search for the network again and register to the LTE network only when the terminal recovers to an IDLE state after waiting for the current data transmission to stop. Therefore, when the terminal is in the EVDO network and has data transmission, the user switches to the LTE network in a manual mode, and the switching response of the terminal is relatively delayed, which not only affects the data transmission rate, but also causes poor user experience.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the notification information access method and the notification information access apparatus is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The existing mobile terminal supporting the LTE network generally has an LTE network switch for a user to manually select, and the switch may be specifically in the form of a "4G switch" or a "preferred network mode". The 4G switch comprises an open state and a close state, and a user can instruct to switch the current network to the LTE network by selecting to open the 4G switch. In the preferred network mode, the options for the user to select generally include "4G first (4G/3G/2G)", "3G first (3G/2G)", "4G only", "3G only", "2G only"; the user may instruct to switch the current network to the LTE network by selecting "4G first (4G/3G/2G)" or "4G only".
In order to increase the speed of switching the mobile terminal from the EVDO network to the LTE network under the condition of manual switching of the user, embodiments of the present invention provide a method, an apparatus, and a mobile terminal for switching the EVDO network to the LTE network, where the mobile terminal in the embodiments of the present invention may be a device such as a mobile phone or a tablet computer that supports switching between the EVDO network and the LTE network. The following detailed description of embodiments of the invention refers to the accompanying drawings.
Example 1
Fig. 1 is a first flowchart of a method for switching an EVDO network to an LTE network according to the present invention. The method is applied to the mobile terminal, and the method flow shown by the embodiment comprises the following steps:
and step S11, setting the D2L timer to enable the D2L timer not to act under the condition that the mobile terminal is in the EVDO network and receives the data connection request.
In the prior art, when a mobile terminal in an EVDO network establishes a data connection, a D2L timer is started, where the D2L timer is based on a situation that the mobile terminal automatically initiates network handover, and a situation that a user manually switches a network is not considered. In the case where the D2L timer exists, even if the user performs a manual switching operation, the user needs to wait until the D2L timer expires or the current data connection is ended (in order to ensure continuity of data transmission), and then the process of switching the network can be started. In the method of this embodiment, the function of the D2L timer for controlling network handover is cancelled, so that the mobile terminal can immediately suspend the current data connection and perform a network handover procedure when receiving a user instruction for switching the network mode to the LTE network.
Exemplarily, in the EVDO network, when the mobile terminal receives the data connection request and establishes the data connection, the D2L timer may be set to be disabled as follows: for example, it may be set not to start the D2L timer, or set a parameter of the D2L timer. As for the setting of the D2L timer parameter, specifically, the timing parameter value of the D2L timer is set to 0 or the processing priority of the D2L timer is set to be lower than the processing priority of the network mode switching.
Wherein, the timing parameter of the D2L timer is set to 0, i.e. the timer does not function. Further, when the data connection is ended or the mobile terminal has successfully switched to the LTE network, the D2L timer may be directly cleared or the timing parameter of the D2L timer may be restored to a default value.
Step S12, under the condition that the user instruction of switching the EVDO network mode to the LTE network is received, judging whether data connection exists currently. If so, step S13 is performed.
Exemplarily, when the mobile terminal is in the EVDO network, if a user instruction for switching the network mode to the LTE network is received, it needs to first determine whether there is a data connection currently, and if the current data connection is not ended, step S13 is executed. If no data connection exists at present, and the mobile terminal is in an idle state at the moment, network searching can be directly carried out and the mobile terminal is registered to the LTE network.
And S13, if yes, suspending the current data connection and switching the network mode of the mobile terminal to the LTE network.
And if a user instruction of switching the network mode to the LTE network by the user is received and the mobile terminal has data connection currently, suspending the current data connection immediately and switching the network mode of the mobile terminal to the LTE network.
And S14, controlling the mobile terminal to recover the data connection under the LTE network.
Exemplarily, in order to facilitate resuming the data connection, when the data connection is suspended, the identification information of the suspended data connection may be recorded, when the data connection is resumed, the identification information of the suspended data connection is searched, and in the LTE network to which the data connection is handed over, the data connection corresponding to the identification information is activated, so as to resume the suspended data connection.
In the method provided by this embodiment, the D2L timer for controlling network switching is correspondingly set to cancel the function of the D2L timer, and when the instruction of the user switching the network mode to the LTE network is received, the current data connection can be immediately suspended for the mobile terminal in the data connection state, so as to perform the network switching process, thereby avoiding the problem that the mobile terminal cannot be switched to the LTE network for a long time when the user manually switches the EVDO network mode to the LTE network, increasing the speed of switching the mobile terminal from the EVDO network to the LTE network, uniformly solving the problem that the reselection to the LTE is slow in two specific scenes before and after the original D2L timer is overtime, improving the efficiency of switching the EVDO network to the LTE network in the data connection state, and improving the experience of the user.
Example 2
Fig. 2 is a flowchart illustrating a second embodiment of a method for switching an EVDO network to an LTE network according to the present invention.
Considering that a user may frequently switch on and off a 3G/4G network switch during operation, which causes repeated switching between an EVDO network and an LTE network of a mobile terminal, and further causes interruption of data transmission, a ping-pong prevention timer is added in the method of this embodiment for control, and based on the above embodiment 1, the method further includes: when judging that the data connection exists currently, starting a ping-pong prevention timer; and in the running process of the ping-pong prevention timer, performing ping-pong prevention processing on the user instruction of receiving the network switching mode again.
For the implementation with the ping-pong prevention timer, fig. 2 shows a specific flow diagram, which includes the following steps:
step S21, the mobile terminal establishes a data connection in the EVDO network.
Step S22, when the data connection is not ended and the mobile terminal receives the user instruction for switching the EVDO network mode to the LTE network, the mobile terminal starts the ping-pong prevention timer, suspends the current data connection, and switches the network mode of the mobile terminal to the LTE network.
The value of the ping-pong prevention timer is set to any value between 3s and 8s, preferably 5s.
And step S23, in the running process of the ping-pong prevention timer, performing ping-pong prevention processing on the user instruction of receiving the switching network mode again.
In this embodiment, the re-received user instruction for switching the network mode may be to switch the network mode to the LTE network, or to switch the network mode to the EVDO network. In practical use of a user, there may be a case where the LTE network is started many times in a short time or is closed again in a short time after the LTE network is started, that is, after the user inputs a handover network instruction for the first time, a handover network instruction is input in a short time.
Specifically, the anti-ping process for the re-received user instruction for switching the network mode includes the following two ways:
(1) Discarding the user instruction for switching the network mode, namely not performing any operation on the user instruction for switching the network mode;
(2) And after waiting for the anti-ping-pong timer to time out, responding to the user instruction for switching the network mode, namely delaying the user instruction for switching the network mode, and waiting for the anti-ping-pong timer to time out and then executing.
If the ping-pong prevention timer has timed out and ended when the user instruction for switching the network mode is received again, that is, the time from the first handover instruction has exceeded the set time value of the ping-pong timer, the handover instruction can be executed normally, that is, the steps in the above embodiment 1 are executed in sequence or the network handover step from the LTE network to the EVDO network is executed.
As another alternative embodiment, as shown in fig. 3, after step S22, the method further includes:
step S31, if the user instruction for switching the network mode is received again, it is determined whether the ping-pong prevention timer is running. If yes, step S32 is performed, and if no, step S33 is performed.
If the anti-ping-pong timer has timed out and ended when receiving the user instruction of switching the network mode again, namely the distance from the first switching instruction exceeds the set time value of the ping-pong timer, the switching instruction can be executed normally, namely the user instruction of switching the network mode is executed normally.
Step S32, if yes, discarding the user instruction for switching the network mode, or waiting for the response after the anti-ping-pong timer is overtime.
In one embodiment, the user instruction to switch the network mode is directly discarded, that is, the user instruction is discarded as a result of no execution operation being performed on the repeated operation of the user, so that it is possible to avoid the interruption of data connection caused by switching the network mode two or more times in a short time.
In another embodiment, the user instruction to switch the network mode may be responded after the current ping-pong prevention timer expires.
Step S33, if not, responding to the user instruction of switching the network mode.
In the method for switching the EVDO network to the LTE network, the ping-pong prevention timer is set to perform ping-pong prevention processing on the user instruction received again in a short time, so that interruption of data connection caused by switching the network mode twice or more in a short time is avoided, stability of data connection is ensured, and user experience is improved.
