Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network switching method, an apparatus, and a mobile terminal.
Background
With the continuous development of communication technology, multi-mode mobile terminals have come into play. A multimode mobile terminal, i.e. a mobile terminal supporting multiple network systems, in other words, a multimode mobile terminal can be used between multiple different technical standard networks.
The multimode mobile terminal necessarily relates to the problem of network switching among multiple network systems. Currently, the third generation mobile communication technology (the 3)thGeneration mobile communication technology, 3G for short) and fourth-Generation mobile communication technology (the 4)thGeneration mobile communication technology, 4G for short) basically switches according to the framework laid out by 3GPP 36.331.
However, at present, there is a Code Division Multiple Access (CDMA) 3G technology evolved to 4G, for example: evolved High Packet network (eHRPD) data. Under the 3GPP 36.331 protocol framework, if switching from an evolved code division multiple access 3G network to a 4G network, only the mobile terminal in idle state can complete network switching, while the mobile terminal in active state cannot perform network switching.
For example: after entering a Long Term Evolution (LTE) network coverage area, the eHRPD mobile terminal in an active state needs to wait for an idle state to be switched to LTE, and the waiting process causes network switching to be too slow, and sometimes even needs to wait for tens of minutes.
High-pass chip manufacturers and the like immediately switch when the idle state arrives through increasing the idle state query time granularity, but the method still needs to wait for the conversion from the active state to the idle state, so that the problem of low switching speed is not substantially improved, and the user experience is poor.

Detailed Description
The main idea of the invention is that if the mobile terminal in the active state needs to perform network switching, the active state is forced to be converted into the idle state, so that the mobile terminal can perform network switching smoothly. The invention does not need to wait for the conversion from the active state to the idle state during network switching, thereby improving the network switching efficiency and improving the user experience effect.
In the cdma 3G technology evolved to 4G, a mobile terminal is defined to have two states, an active state and an idle state. The active state means that a network interface connection has been established between the mobile terminal and the accessed network, and data is uploaded or downloaded through the network interface. The idle state means that the mobile terminal is disconnected from the accessed network through the network interface.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
The present invention provides a network switching method, as shown in fig. 1, which is a flowchart of a network switching method according to an embodiment of the present invention.
Step S110, in the activated state, if a network switching request is received, the activated state is converted into an idle state.
In an idle state, if a network handover request is received, network handover is directly performed.
And the network switching request is used for requesting to switch the evolved code division multiple access 3G network to the 4G network. Further, the network switching request may be issued by a user operation, such as: a user switches the network through a preset switch; the network handover request may also be sent by the mobile terminal itself, for example: network handover due to neighbor measurement or timing detection.
In the prior art, a mobile terminal in an active state is converted into an idle state by two levels of time thresholds. Further, setting a first time threshold and a second time threshold, starting to perform idle state monitoring on the mobile terminal when the time period when the mobile terminal does not receive or send the data packet reaches the first time threshold, and if the time period when the mobile terminal does not receive or send the data packet reaches the second time threshold, indicating that the data transmission of the mobile terminal is idle, and converting the current state of the mobile terminal from an active state to an idle state.
In this embodiment, if the mobile terminal in the active state needs to perform network handover, the active state is forced to be converted into the idle state, and it is not necessary to care whether the mobile terminal is receiving or sending a data packet, and whether the time length during which the mobile terminal does not receive and send the data packet reaches the sum of two-stage time thresholds. As such, in the present embodiment, the time for switching from the active state to the idle state in the prior art is omitted, so that the time cost for network switching is reduced, and the network switching efficiency is improved.
Step S120, after the active state is converted into the idle state, performing network switching.
After converting the active state into the idle state, network handover is performed according to the 3GPP 36.331 protocol.
In one embodiment, to ensure the continuity of the service, after the active state is converted into the idle state and before the network handover is performed, the data packet to be sent to the network device is buffered, and after the network handover is performed, the buffered data packet is sent to the network device.
Performing a network handover includes two results, namely a network handover success and a network handover failure. If the network switching is successful, sending the cached data packet to the network equipment through the newly accessed network; if the network switching fails, the network accessed by the mobile terminal is not changed, the current state of the mobile terminal is converted from the idle state to the active state, and the data packet is sent to the network equipment through the originally accessed network. Further, according to the 3gpp2x.s0057 protocol, the handover from the evolved cdma 3G network to the 4G network belongs to a smooth handover, and the IP address of the mobile terminal is not changed before and after the handover, so that after the handover is successful, the mobile terminal may perform target addressing through the newly accessed network to send the buffered data packet to the target network device.
The invention also provides a network switching device, as shown in fig. 2. The network switching device can be arranged in a mobile terminal, and the mobile terminal performs network switching based on the network switching device.
The device includes:
a conversion module 210, configured to, in an active state, convert the active state into an idle state if a network handover request is received.
An executing module 220, configured to execute network handover after the active state is converted into the idle state.
In one embodiment, the conversion module 210 is further configured to convert the idle state back to the active state in case of a network handover failure.
In another embodiment, the apparatus further includes a buffer module (not shown) for buffering the data packets to be sent to the network device. The apparatus further includes a sending module (not shown) configured to send the buffered data packet to the network device.
The functions of the apparatus in this embodiment have already been described in the method embodiment shown in fig. 1, so that reference may be made to the related descriptions in the foregoing embodiments for details which are not described in this embodiment.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
