Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.Accompanying drawing number is only used for each step in differentiation scheme in the application, is not used in limit
Fixed each step executes sequence, and specific execution sequence is subject in specification and is described.
In the communications field, 4G network is gradually popularized, and terminal device can carry out network communication by 4G network, but due to letter
Reasons, the terminal device occasionals such as number weak, connection error of intensity are disconnected with 4G network.Section terminating equipment uses when communicating
" 4G+2G " network interworking form is communicated, i.e. terminal device can enter 2G network after disconnecting with 4G network, this
The form of kind network interworking can guarantee the basic communication requirement of user.Wherein, 2G refers to Generation Mobile Telecommunication System technology, and 4G refers to
Fourth generation mobile communication technology.
In existing method for switching network, referring to Fig. 1, after terminal device enters 2G network, circuit is carried out first
Exchange the domain (Circuit Switched, CS) registration, the domain CS registration process be a kind of location updating process, terminal device to
2G network registry location area information pages network side in the domain CS to terminal device.
After the completion of the domain CS is registered, it is grouped the domain exchange (Packet Switch or Packet Service, PS) immediately
Registration.Ps domain registration specifically includes Routing Area Update (Route Area Update, RAU), and terminal device is to 2G network registry road
By area's information, allow network side in ps domain paging to terminal device.In addition, ps domain registration further includes random access, terminal is set
Preparation send random access request, and network side executes random access to terminal device.
After random access success, terminal device often receives ps domain authentication request, is asked according to the authentication received
It asks, terminal device feeds back authentication code to network side, and after network side passes through authentication code authentication, the RAU of receiving terminal equipment is registered
Request sends RAU to terminal device and registers acceptance message, and then, ps domain correlation function can be used in terminal device.
After terminal device completes the domain CS and the ps domain registration of 2G network, that is, reside in after 2G network, Cai Huijin
Row isosystem measurement (Inter Radio Access Technology, IRAT), to find accessible 4G network.Existing
In some communication systems, with popularizing for 4G network, the maintenance of 2G network related facility is reduced, compared with 4G network, 2G net

The ps domain authentication request sent.
After 3. terminal device receives ps domain authentication request and feeds back Authentication Response, due to network delay is longer etc.,
The RAU registration acceptance message of network side transmission is not received immediately.
For the above-mentioned problems of the prior art, the application provides a kind of method for switching network, and executing subject can be
Terminal device is illustrated by taking " 4G+2G " network interworking model as an example below, and this method is to keep terminal device lower in entrance
The communication network of higher-version is rapidly switched to after the communication network of version.Referring to fig. 2, method provided by the present application include with
Lower step:
S21: circuit-switched CS domain registration is completed having accessed cell.
When terminal device is after having accessed the cell completion domain CS registration, often with basic 2G communication function, for example,
Can be conversed, receive and dispatch short message by having accessed cell etc..
S22: determining whether to detect to persistent district, and the version of the communication protocol supported to persistent district is higher than institute
State the version for having accessed the communication protocol of cell support.
In " 4G+2G " network interworking model, after terminal device is disconnected with 4G network, it is small that 2G network can be accessed
Area, having accessed cell in the present embodiment can be the network cell 2G.After terminal device enters the network cell 2G, electricity is carried out first
Road exchanges the registration of the domain CS, and after the completion of the domain CS is registered, terminal device is able to use the domain the CS correlation function of 2G network.At this point,
Before ps domain registration, it is determined whether detect to persistent district, wherein the version of the communication protocol to persistent district support is higher than
The version of the communication protocol of cell support is accessed.
Specifically, can determine whether to detect by isosystem measurement to persistent district, in " 4G+2G " network interworking mould
In type, when to have accessed cell be the network cell 2G, the network cell 4G can be to persistent district.For other kinds of networking mould
Type, when it is the network cell 2G that terminal device, which has accessed cell, since 2G communication protocol is supported in the network cell 2G, all supports
Communication protocol version is higher than the network cell of 2G communication protocol, can be used as to persistent district, such as: supporting the 3G of 3G communication protocol
Network cell, the network cell 5G for supporting 5G communication protocol etc..
S23: confirmly detect it is described to persistent district in the case where, be resident to the target in persistent district and wait for
Persistent district.
When it is the network cell 2G that terminal device, which has accessed cell, if detecting the available network cell 4G, it is determined that
Detect network cell to be resident.At this point, terminal device can be resident by the correlation step of network reselection to small wait be resident
Target in area waits for persistent district.
Referring to Fig. 3, after terminal device enters 2G network and completes the registration of the domain CS, it is determined whether detect small wait be resident
Area executes network reselection to persistent district to what is detected, to carry out PS in terminal device when detecting when persistent district
4G network is switched back into before the registration of domain, without executing in Fig. 3 original ps domain registration shown in dotted line frame.
S24: wait for that packet switched ps domain registration is initiated in persistent district in the target.
After being resident and waiting for persistent district to the target in persistent district, wait for that persistent district carries out ps domain in target
Registration, furthermore it is also possible to execute other required registration steps, enables terminal device to wait for that persistent district is led to by target
Letter.
By above scheme provided by the present application, when terminal device accessed support it is small compared with the network of lowest version communication protocol
Qu Shi detects network function preferably to persistent district in time.Enable terminal device detected before carrying out ps domain registration to
Persistent district carries out network switching to persistent district once detecting in time, shortens terminal device and has accessed the communication of cell
Time, network access function is preferably to persistent district as early as possible.It avoids causing due to having accessed subzone network delay length etc.
Terminal device is in the poor network environment of network function for a long time, so as to improve the network function of terminal device, optimizes net
Network experience.
The method based on the above embodiment, as shown in figure 4, in above-mentioned steps S22, it is determined whether detect to resident
Cell, comprising the following steps:
S221: within a preset time, the broadcast message from the network equipment is detected.
It can specifically be detected by the correlation step of isosystem measurement to persistent district, and then determine whether to detect wait stay
Stay cell.In this step, detection time can be preset by timer, the starting point of preset time can be start detection to
At the time of persistent district.For example, preset time is 5 seconds, then start detection to persistent district, and continue to detect 5 second time, then
It can stop detecting, corresponding step is executed according to this 5 seconds testing result.The broadcast message can be is led to by the network equipment
Cross the message that the form of broadcast is sent.Within a preset time, terminal device receives the broadcast message sent by the network equipment, and right
The broadcast message received is analyzed.
S222: according to the frequency point information of the corresponding cell of the broadcast message, it is determined whether detect described small wait be resident
Area.
The corresponding cell that broadcasts the message can specifically refer to, send the cell of the broadcast message.Terminal device is according to reception
The broadcast message arrived can analyze the frequency point information for obtaining the cell for sending the broadcast message.According to sending the broadcast message
Whether the frequency point information of cell, the communication function that may further determine that the corresponding cell of the broadcast message provides are better than having accessed
The communication function that cell provides.It, can be with when the cell corresponding with broadcast message detected can provide more preferably communication function
It has confirmly detected to persistent district.
Scheme provided by the present application can within a preset time detect from the broadcast message of the network equipment by way of,
Determine whether to detect to persistent district.Cell can be known indirectly by the frequency point information of the corresponding cell of analysis broadcast message
More preferably communication function can be provided, then to carry out network switching by modes such as gravity treatments.In addition, if in preset time
It is inside not detected to persistent district, can continue to carry out PS registration in having accessed cell, temporarily reside in and accessed cell.This
Scheme detects the broadcast message from the network equipment within a preset time, is avoided that long lasting for detection, and then avoids pair
PS registration impacts, and guarantees terminal device in the basic communication functions for having accessed cell.
Preferably, the method based on the above embodiment, as shown in figure 5, above-mentioned steps S222, comprising the following steps:
S2221: according to the frequency point information of the corresponding cell of the broadcast message, the corresponding cell of the broadcast message is determined
Resident priority.
Under normal conditions, terminal device can analyze the cell for sending the broadcast message according to the broadcast message received
Frequency point information, and then resident priority is analyzed according to the frequency point information of cell.The resident priority can specifically refer to public affairs
Priority altogether.In addition, dedicated priority can also be determined as this if including dedicated priority in the broadcast message received
The resident priority for the corresponding cell that broadcasts the message.
Specifically, multiple resident priority can be divided in advance according to the network function of network cell, formed resident preferential
Grade standard, such as: the resident priority of the network cell 2G is 1, and the resident priority of 3G network cell is staying for the network cell 2,4G
Staying priority is 3, and so on.In addition, the network cell for supporting homogeneous networks agreement, it can also be strong according to network signal
The standards such as degree, network function, the multiple resident priority of further division.
S2222: there is resident priority in the corresponding cell of the broadcast message and accessed staying for cell higher than described
In the case where the cell for staying priority, confirmly detect described to persistent district.
Through the above steps after the resident priority of the determining corresponding cell that broadcasts the message of S2221, what be will test is small
The resident priority in area is compared with the resident priority for having accessed cell.For example, having accessed cell is the network cell 2G, then
According to the resident priority criteria divided in above-described embodiment, the resident priority for having accessed cell is 1.When the cell detected
When for the network cell 4G, the resident priority for the corresponding cell that broadcasts the message is 3.At this point, being deposited in the corresponding cell that broadcasts the message
It is higher than the cell for having accessed the resident priority of cell in resident priority, has confirmly detected to persistent district, it should be to resident
Cell can be the network cell 4G detected.
Technical solution provided by the present application determines staying for the cell for sending the broadcast message according to the broadcast message received
Priority is stayed, and then determines whether to detect to persistent district according to resident priority.It can be known according to resident priority
The network function of cell.The resident higher cell of priority can provide preferable network function, be resident the lower cell of priority
The network function of offer is poor, therefore, it is smaller than existing can to know whether the cell detected can provide according to resident priority
Area's more preferably network function.When the cell detected can provide more preferably network function, confirmly detect to persistent district,
Subsequent terminal device can switch to the higher cell of resident priority detected by modes such as network reselections, set terminal
It is standby to be in more preferably network environment, optimize web experience.
The method based on the above embodiment, as shown in fig. 6, when the quantity to persistent district be it is multiple, it is described
Method is further comprising the steps of:
S25: according in multiple network cells to be resident be resident highest priority the quantity to persistent district, determine described in
Target waits for persistent district.
Step S25 provided by the present application can be resident to the target in persistent district in terminal device and wait being resident
It is executed before cell.
Under normal conditions, when terminal device detection is from the broadcast message of the network equipment, it can detect that multiple broadcast disappear
Breath, different broadcast messages is often from the different network equipments.By above-mentioned analysis, it is possible to analyze multiple to resident
Cell.
For example, having accessed cell is the network cell 2G, being resident priority is 1.Detecting includes one to persistent district
The network cell 4G that the 3G network cell and a resident priority that resident priority is 2 are 3.At this point, resident priority is most
High is the network cell 4G to persistent district.The quantity to persistent district of resident highest priority is 1, at this point, will test
Only one be resident being determined as target to persistent district (network cell 4G) and waiting for persistent district for highest priority.
It is multiple when persistent district when detecting by scheme provided by the present application, it can be according to network cell to be resident
Priority further realize screening, obtain that the network cell of optimal network function can be provided, optimal network function will be provided
Network cell be determined as target and wait for persistent district.Then network switching can be carried out by modes such as network reselections, make terminal
Equipment can use preferably network function, optimize web experience.
The method based on the above embodiment can when resident highest priority is when the quantity of persistent district is greater than 1
With further analyzing to persistent district to resident highest priority, the network cell for meeting actual demand is filtered out, it will
The only one filtered out is optimal to be determined as target to persistent district and waits for persistent district.
Such as: pass through above-mentioned analysis, includes that resident priority is 3 network cell 4G A, and is resident excellent to persistent district
The network cell the 4G B that first grade is 3.At this point, the quantity to persistent district of the resident highest priority be it is multiple, such as Fig. 7 institute
Show, above-mentioned steps S23 may comprise steps of:
S251: the gravity treatment complexity to persistent district of multiple resident highest priorities is determined.
Specifically, it is small that terminal device can further analyze 4G network for the multiple to persistent district of highest priority
The gravity treatment complexity of the area network cell A and 4G B, gravity treatment complexity can be to be analyzed according to multi-signal parametric synthesis and obtain
Parameter relevant to gravity treatment.For example, can be according to cell signal strength, signal quality etc., to the network cell 4G A and 4G network
Cell B is compared, by be easier to carry out gravity treatment to be determined as gravity treatment complexity to persistent district minimum to persistent district.
S252: it is determined as gravity treatment complexity is minimum the target to persistent district and waits for persistent district.
Gravity treatment complexity can characterize gravity treatment speed and reselection success rate, and gravity treatment difficulty is minimum to persistent district i.e. weight
Select that speed is fast and the higher cell of success rate.
By analyzing the gravity treatment complexity of multiple cells, can obtain be easier to gravity treatment to persistent district.By gravity treatment difficulty or ease
Degree is minimum to be determined as target to persistent district and waits for persistent district, then can make terminal device gravity treatment by modes such as gravity treatments
Persistent district is waited for target.Through the above steps, terminal device can be made to reselect to the cell of highest priority and most easy gravity treatment.
On the one hand terminal device is in preferably network environment after guaranteeing gravity treatment, on the other hand guarantees that reuse adoption process speed is fast, gravity treatment
Success rate is high.
The method based on the above embodiment, in the case where being not detected to persistent district, as shown in figure 8, also wrapping
Include following steps:
S26: before receiving ps domain authentication request, it is determined whether detect described to persistent district.
Referring to Fig. 3, terminal device can continue to execute shown in dotted line frame in the case where being not detected to persistent district

Enter request.After random access success, before terminal device receives the ps domain authentication request of network equipment transmission, determination is
It is no to detect to persistent district.
In the present solution, determining whether to detect when persistent district for the first time, terminal device is possible to be not in resident
In cell coverage area, then, terminal device is possible to be moved to in the coverage area of persistent district.Therefore, it is detected for the first time
In the process, it is not detected to after persistent district, it is possible to detect in subsequent detection process to persistent district.
It may include described in above-described embodiment specifically, determining whether to detect the method and step to persistent district
