Description

Method for generating web search list, web search method and corresponding device

This application requires the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on December 26, 2018, with the application number 201811602882.3 and the invention titled "a method for generating a search list, search method and corresponding device". The entire contents are incorporated by reference in this application.

Technical field

This application relates to the field of communication technology, and in particular to a method for generating a search list, a search method, and a corresponding device.

Background technique

Public Land Mobile Network (PLMN, Public Land Mobile Network) is a network used to provide land mobile communication services to the public. The network is usually interconnected with the public switched telephone network to form a communication network of the same size in the entire region or country. In this case, user equipment (UE) can communicate through PLMNs provided by various operators.

With the development of communication technology, various operators can support multiple types of network standards. Due to commercial factors and other considerations, sometimes equipment leases occur between operators, that is, operator A leases equipment of operator B in some regions or in certain systems, so that there is no need to operate in or for that region Configure the corresponding device. For example, China Mobile can support global mobile communication system (GSM), time division-synchronous code division multiple access (time division-synchronous code division multiple access, TD-SCDMA) and time division long-term evolution (time division long) term evolution, TD-LTE) and other network standards, and China Unicom can support network standards such as GSM. In some regions, China Mobile can only set up the equipment required for TD-SCDMA and TD-LTE, and rent China Unicom to set up in the region The equipment required for the GSM network standard, so there is no need to set up the equipment required for GSM.

Among them, if operator A leases the equipment of operator B, in order to enable operator A’s subscriber identity module (SIM) to communicate under the communication network corresponding to the leased equipment, network support is usually set on the SIM card Information, the network support information indicates that during the network search process of the SIM card, the communication networks of each network standard supported by operator A and operator B will be regarded as equivalent home networks (Equivalent HPLMN, EHPLMN), thereby enabling the UE The communication network corresponding to the leased equipment is searched so that the communication network can be used to realize communication.

However, the inventor discovered in the research process of this application that, in the prior art, if the UE applying the SIM card of the operator A resides in the communication network corresponding to the leased device, after the network switch occurs, since the UE is in the network Before the handover, the network is located under the communication network corresponding to the leased equipment provided by operator B. Therefore, during the network search process, the UE will preferentially select other network formats supported by operator B, and determine that other networks that cannot be supported by operator B After the network is implemented under the standard, the network standard supported by operator A will be searched, so as to communicate through the network standard supported by operator A. The process of searching the network under other network formats supported by operator B will take a while, so it will lead to longer time for the network searching process, resulting in a slower network search, further affecting the speed of the network and reducing the network Network efficiency, resulting in poor user experience.

detailed description

The solutions disclosed in the embodiments of the present application are applied to user equipment capable of performing communication services, such as smart phones and telephone watches. Referring to the schematic diagram of the user equipment shown in FIG. 1, the user equipment includes a non-access layer (Non-access Stratum, NAS) and an access layer (Access Stratum, AS), where the non-access layer is the core network and the user equipment The functional layer between can support the signaling and data transmission between the core network and the user equipment. The access layer usually refers to the part of the network that is oriented to user connection or access, and is used to connect the user equipment to the network.

In the solution disclosed in the embodiment of the present application, the non-access layer can interact with the storage module of the network access information to obtain the network access information, and generate a search list accordingly. In addition, the non-access layer can interact with the access layer, so that the access layer can obtain a search list, and the access layer can implement a network based on the search list.

In order to clarify the solutions disclosed in the embodiments of the present application, the solutions of the present application are disclosed below through various embodiments.

The first embodiment of the present application discloses a method for generating a web search list. Referring to the schematic diagram of the working process shown in FIG. 2, the method for generating a web search list includes the following steps:

Step S11: The non-access layer in the user equipment UE obtains network access information of the UE, where the network access information includes an equivalent home network EHPLMN of the UE and a network type corresponding to the EHPLMN.

The network access information may be pre-stored in the local cache space of the UE, for example, may be stored in the non-volatile flash memory space of the UE, or may be pre-stored in the SIM card of the UE. In addition, the network access information may also be located in the server. That is, the storage module of the network access information may be a local cache space of the UE, a SIM card, and/or a server. When the network access information is located in the server, and the UE has not completed camping on the network, the UE can access the server by connecting to the wireless network wifi, etc., so that the non-access layer can obtain network access information.

The network access information includes an equivalent home network EHPLMN of the UE, and a network type corresponding to the EHPLMN. Among them, EHPLMN refers to the list formed by the home network (Home PLMN, HPLMN) supported by the SIM card in the UE. The HPLMN supported by the SIM card can be expressed in the form of a network code. For example, the operator of China Mobile The HPLMN supported by the SIM card includes: 46000, 46002, and 46007. The HPLMN supported by the SIM card of China Unicom is 46001. The network type corresponding to EHPLMN refers to the type of the network corresponding to the home network supported by the SIM card in the UE, respectively, where the network type may be GSM, TD-SCDMA, TD-LTE, etc.

If China Mobile installs only the equipment required for TD-SCDMA and TD-LTE network types in a certain area, and leases the equipment required for GSM installed by China Unicom in this area, in this case, China Mobile’s SIM is applied The EHPLMN of the card UE in the region includes: 46000, 46002, 46007 and 46001. In addition, the network types corresponding to 46000, 46002 and 46007 include various types of networks of China Mobile, namely GSM, TD-SCDMA and TD-LTE. The network type corresponding to 46001 is the type of network supported by the leased equipment of China Unicom. That is GSM.

Step S12: Based on the network access information, the non-access layer determines the target network searched during the network search process when the UE communicates through various network types.

For example, if the EHPLMN in the access information includes: 46000, 46002, 46007, and 46001, and the corresponding network types of 46000, 46002, and 46007 include various types of networks of China Mobile, namely GSM, TD-SCDMA, and TD-LTE, The network type corresponding to 46001 is the type of network supported by the leased equipment of China Unicom, which is GSM. In this case, the UE switches to 2G, that is, the network type that GSM is used for communication is searched during the network search process. The target networks include 46000, 46002, 46007, and 46001; when UE switches to 3G, that is, when the TD-SCDMA network type is used for communication, the target networks searched during the network search include 46000, 46002, and 46007; the UE switches to 4G, that is, when using the TD-LTE network type for communication, the target networks searched during the network search include 46000, 46002, and 46007.

Step S13: The non-access stratum generates a network search list including the corresponding relationship between the network type and the target network based on the target network searched by the UE during the network search process.

After obtaining the search network list, the access layer can determine the corresponding target network according to the corresponding network type when the network is on the network, and search the target network.

An embodiment of the present application discloses a method for generating a network search list. In this method, a non-access layer in a UE obtains network access information of the UE, and the network access information includes an equivalent home network EHPLMN of the UE , And the network type corresponding to the EHPLMN; then, based on the network access information, the non-access layer determines the target network searched during the network search process when the UE communicates through each network type; non-access The layer generates a search network list including the correspondence between the network type and the target network based on the target network searched by the UE during the network search process.

In the prior art, if operator A leases the equipment of operator B, each communication network supported by operator A and operator B will be set in the equivalent home network EHPLMN of the SIM card. For example, the operator of China Mobile supports 2G GSM communication network, 3G TD-SCDMA communication network and 4G TD-LTE communication network, while China Unicom operator supports 2G GSM communication network and 3G broadband code division Multi-access (wideband code division multiple access, W-CDMA) communication network and 4G frequency division long-term evolution (FDD-LTE) communication network, in this case, if China Mobile can Only the equipment required for the two network types TD-SCDMA and TD-LTE is set, and the equipment required for GSM set by China Unicom in the region is rented. The EHPLMN of China Mobile’s SIM card includes 46000, 46002, 46007, and 46001 .

In this case, if the SIM card of operator A resides in the communication network corresponding to the leased device, after the network switch occurs, the SIM card resides in the communication network corresponding to the leased device provided by operator B before the network switch. Therefore, the SIM card will preferentially select other network formats supported by operator B during the network search process, and determine that the network supported by operator A will not be supported until the network cannot be implemented under other network formats supported by operator B. Search the network in order to communicate through the network standard supported by operator A. The process of searching the network under other network formats supported by operator B will take a while, so it will lead to longer time for the network searching process, resulting in a slower network search, further affecting the speed of the network and reducing the network Network efficiency, resulting in poor user experience.

For example, if the UE is camped on GSM, after the network handover occurs, the UE switches to the 3G network, and when the UE was camped on GSM, the device communicates through China Unicom’s equipment, and the UE’s EHPLMN includes both China Mobile and China. For the communication network supported by Unicom, after the UE switches to the 3G network, in the search process, it will first search and try to register the 3G network provided by China Unicom (ie 46001), but it will be denied access by China Unicom. After the search time, it will show that the search failed. Then, according to the records of EHPLMN, the UE searches for 3G networks provided by China Mobile (ie 46000, 46002 and 46007). The process of searching for the 3G network provided by China Unicom will take a while, resulting in a longer time for the entire search process, which further slows down the speed of the network and reduces the efficiency of the network, thereby affecting the user experience.

According to the solution disclosed in the embodiment of the present application, the search list generated by the non-access layer contains the correspondence between the network type and the target network. In this case, the access layer searches the network according to the search list , According to the network type when searching the network, you can determine the target network to search, so as to avoid searching for unsupported communication networks, reduce the time required for the search process, further speed up the network speed, improve the efficiency of the network, and improve users Experience.

For example, through the solution of the embodiment of the present application, the network type corresponding to EHPLMN can be characterized in the search network list. In this case, the UE switches from 2G to 3G (that is, the application of the TD-SCDMA network type is required to communicate) , It can be determined that the target networks searched during the search process include 46000, 46002 and 46007. In other words, through the search network list obtained by the embodiment of the present application, the access layer will directly search for 46000, 46002, and 46007, instead of searching for the 3G network provided by China Unicom (that is, 46001), thereby avoiding searching for unsupported communication networks .

In the prior art, the EHPLMN supported by the SIM card is usually recorded in the EHPLMN list, and the forbidden network (Forbidden PLMN, FPLMN) of the SIM card can also be recorded in the FPLMN list. Among them, each communication network described in the EHPLMN list and the FPLMN list is usually represented by 3 bytes.

For example, in the prior art, the EHPLMN list can be represented by Table 1:

Table 1

BytesBytes	DescriptionDescription	LengthLength
1 to 31 to 3	1st PLMN1st PLMN	3bytes3bytes
::	::	A
22 to 2422 to 24	8th PLMN8th PLMN	3bytes3bytes

Among them, Table 1 shows that 1 to 3Byte describes the first communication network in EHPLMN, the description occupies a length of 3bytes, 22 to 24Byte describes the eighth communication network in EHPLMN, the description occupies a length of 3bytes .

In this embodiment of the present application, two more bytes may be added at corresponding positions of each communication network included in the EHPLMN list to represent network access information. For example, the network access information of the UE can be represented by Table 2:

Table 2

Among them, Table 2 shows that 1 to 3Byte describes the first communication network in EHPLMN (such as 46000), the description occupies a length of 3bytes, 4 to 5Byte describes the corresponding network type of the communication network (such as GSM), The description occupies a length of 2 bytes; 36 to 38 Byte describes the eighth communication network in EHPLMN, the description occupies a length of 3 bytes, 39 to 40 Byte describes the corresponding network type of the communication network, and the description occupies 2 bytes length.

Of course, the network access information can also be expressed in other forms, which is not limited in the embodiments of the present application.

Further, in the embodiment of the present application, the non-access stratum acquiring network access information of the UE includes one or more of the following options:

The SIM card may be in various forms. For example, the SIM card may be a physical SIM card, and may also be an embedded SIM card (Embedded-SIM, eSIM), which is not limited in this embodiment of the present application.

Further, network access information may change. For example, if the equipment lease relationship between operators changes, the network access information also changes accordingly. In order to avoid affecting the UE's web search results, the network access information can also be updated.

In this case, when the network access information is stored in the storage space of the UE or the SIM card, the method disclosed in this embodiment of the present application further includes:

Among them, the non-access layer can access the cloud when the network is on the network, or the non-access layer can also access the cloud by connecting to the wireless network.

In addition, when the network access information is stored in the storage space of the UE, update software may also be provided in the UE, and the update software may perform network access information in the storage space of the UE through the obtained update data package. Update. The update data package may be a software package generated by the UE manufacturer for system upgrade.

Further, in the embodiment of the present application, after the non-access layer obtains the network search list, the access layer needs to perform network search according to this. In this case, after the non-access layer generates a search list that contains the correspondence between the network type and the target network, it also includes:

The non-access stratum transmits the network search list to the access stratum in the UE.

Alternatively, after the non-access layer generates a search list that includes the correspondence between the network type and the target network, the method further includes:

The non-access layer determines the target network type for this search;

Through the above steps, the non-access layer splits the search network list according to the target network type of the current search network. The split search network list includes the target network corresponding to the target network type, and the split search network The network list is transmitted to the access layer, so that the access layer can search the network according to the split network search list.

For example, when the search network list indicates that the networks supported by the SIM card include: 46000, 46002, 46007, and 46001, the network types corresponding to 46000, 46002, and 46007 are GSM, TD-SCDMA, and TD-LTE, while the network type corresponding to 46001 is In GSM, it can be determined that the target networks corresponding to the GSM network type include 46000, 46002, 46007, and 46001, and the target networks corresponding to TD-SCDMA and TD-LTE are 46000, 46002, and 46007. If the target network type of this search is TD-SCDMA, the target networks included in the split search list include 46000, 46002, and 46007. In this case, after receiving the split search list, the access layer searches according to the split search list.

In order to explain in detail how the non-access layer determines the target network type of this search, this application discloses another embodiment, see FIG. 3, in this embodiment, the non-access layer determines the target network of this search Types include the following steps:

Step S21: When generating the search network list for the first time after the UE is turned on, the non-access layer obtains the UE during the last startup process by querying the usage log of the UE. The network type of the applied communication network.

Step S22: The non-access stratum determines that during the last booting process of the UE, the network type of the last applied communication network is the target network type of the current network search.

In other words, the target network type of this search can be determined through the historical usage of the UE.

For example, if the search network list is generated for the first time after the UE is turned on, and by querying the usage log of the UE, it is determined that the last time the UE was turned on, the network type of the communication network last applied is TD -SCDMA, then the non-access layer determines that the target network type for this search is TD-SCDMA. That is to say, when generating the network search list for the first time after the UE is turned on, the target network type of the network search is determined according to the communication network last applied by the UE during the last startup process.

Or, in another way, the non-access stratum determines the target network type of the current network search, which includes: after receiving the first network switching operation, the non-access stratum switches based on the first network Operate to determine the target network type for this search.

The first network switching operation can indicate the target network type of the current network search, for example, the first network switching operation is used to make the display screen of the UE display multiple network types, and select a certain network type as the target network Types of. After receiving the first network switching operation, the non-access stratum determines the target network type for the current network search based on the first network switching operation.

In an example, the display interface of the display screen of the UE may be as shown in FIG. 4, wherein, on the display interface, a network list is displayed, and the network list includes multiple network standards, for example, 2G, 3G, and 4G, When the user performs the first network switching operation, the display screen of the UE may display the interface, and according to the network format selected by the user, use the corresponding network type as the target network type.

Among them, for the SIM cards provided by different operators, each network standard corresponds to the type of network supported by the operator. For example, when the SIM card in the UE is a SIM card provided by a China Mobile operator, 2G corresponds to GSM and 3G corresponds to TD -SCDMA and 4G correspond to TD-LTE. In this case, when the user selects 3G, the network type TD-SCDMA corresponding to 3G is the target network type.

Further, if the display interface of the display screen of the UE is as shown in FIG. 4, in the box after each network standard, information such as the priority of the network standard can also be displayed.

During the use of the UE, the user may perform a network switching operation on the UE to cause the UE to perform network switching, for example, switching TD-SCDMA applied to the UE to TD-LTE. In this case, through the above steps, the non-access layer can determine the target network type for the current network search according to the network switching operation that is accessed.

Or, in another way, referring to the schematic workflow diagram shown in FIG. 5, the non-access stratum determines the target network type for this network search, which includes the following steps:

Step S31. The non-access stratum obtains the preset priority corresponding to each network type.

Step S32: The non-access layer determines that the network type with the highest current priority is the target network type for network search;

Step S33: When the network search with the highest priority network type fails and the network search fails, the non-access layer sequentially selects other network types as the current search based on the priority level corresponding to each network type The target network type of the network.

In the embodiment of the present application, the user may set the priority corresponding to each network type in advance. In this case, the non-access layer determines the target network type according to the set priority. Specifically, the non-access layer determines that the network type with the highest priority is the target network type for this network search. If the access layer fails to search the network in this case, the non-access layer selects the priority after The network type with the highest priority is the target network type for this search. That is to say, the scheme selects the target network type in turn according to the preset priority of each network type.

In addition, in order to meet the diversified needs of users, the priority corresponding to each network type can be modified. For example, at the beginning of each month, the UE’s network traffic is abundant, and users pay more attention to network speed. In this case, the TD-LTE network type can be set to have the highest priority, so that the access network will have priority when searching the network. Search for TD-LTE networks; in addition, at the end of the month, the UE has fewer network processes, and users want to save traffic. In this case, you can set the GSM network type to have the highest priority so that the access network can search for the network. , Will give priority to search GSM network.

Among them, if the display interface of the display screen of the UE is as shown in FIG. 4, in the box after each network standard, the priority of the network standard can also be displayed, and the user can also modify the information in the box To modify the priority of each network standard. For SIM cards provided by different operators, each network standard corresponds to the network type supported by the operator. By modifying the priority of each network standard, the priority of each network type can be modified.

For example, when the SIM card in the UE is a SIM card provided by a China Mobile operator, 2G corresponds to GSM, 3G corresponds to TD-SCDMA, and 4G corresponds to TD-LTE. In this case, when the user changes the priority of 3G, the priority of TD-SCDMA is modified accordingly.

Further, the non-access layer can also determine the target network type of the network search based on the application parameters of the UE. In this case, referring to the schematic diagram of the work flow shown in FIG. 6, the non-access stratum determines the target network type of the current network search, which includes the following steps:

Step S41: After receiving the second network switching operation, the non-access stratum obtains application parameters of the UE, where the application parameters include: address and/or time.

Wherein, the second network switching operation is used to indicate that a network switching is currently required, so that the non-access layer determines the target network type for this network search.

In the UE, a clock is usually built in, and the non-access layer can obtain the time through the clock built in the UE. In addition, the UE can realize the UE positioning through the wireless network, so that the non-access layer can obtain the UE's address. For example, the UE can connect to wifi to achieve positioning through the Global Positioning System (GPS), thereby enabling the non-access layer Get the address of the UE.

Step S42: The non-access stratum determines the priority of each network type based on the application parameters of the UE and the correspondence between the preset application parameters and the priority of the network type.

In the embodiment of the present application, a correspondence relationship between application parameters and network type priorities is preset, and the correspondence relationship may be stored in the form of a table or the like. And, according to the needs of users, the corresponding relationship can be modified.

Step S43: The non-access layer determines that the network type with the highest priority is the target network type for the network search.

In the embodiment of the present application, the non-access layer obtains the application parameters of the UE, and determines the priority of each network type based on the correspondence between the application parameters of the UE and the preset application parameters and the priority of the network type. The network type with the highest priority is used as the target network type for this search.

Through the solution of the embodiment of the present application, the non-access layer can determine the priority of each network type based on the application parameters, and further determine the target network type for this network search. For example, if a user departs from location A to work in location B every day, the TD-LTE signal strength in location A is strong, and the GSM signal strength in location B is strong. When the UE is located in location B, GSM has the highest priority. In this case, when the non-access layer determines that the UE is located in the A location according to the application parameters, it can be determined that the network type of TD-LTE is the target network type for this network search; when the non-access layer is based on the application parameters, When it is determined that the UE is located at the location B, it can be determined that the GSM network type is the target network type for the network search.

Or, in another way, referring to the schematic workflow diagram shown in FIG. 7, the non-access stratum determines the target network type for the current network search, which includes the following steps:

Step S51. After receiving the third network switching operation, the non-access stratum obtains application parameters of the UE, where the application parameters include: address and/or time.

The third network switching operation is used to indicate that network switching is currently required, so that the non-access layer determines the target network type for this network search.

In addition, the non-access stratum can obtain the time through the clock built in the UE. In addition, the UE can implement UE positioning through a wireless network, so that the non-access stratum can obtain the UE's address. For example, the UE can achieve positioning by connecting to wifi and GPS, so that the non-access stratum can obtain the UE's address.

Step S52: When the UE is connected to a wireless network, the non-access layer obtains the signal strength ranking of each network type under the application parameters by accessing the server.

When the UE is connected to the wireless network, the UE can access the server, so that by accessing the server, the signal strength ranking of each network type under the application parameters can be obtained. For example, if the application parameter is a location, you can access the server to obtain the signal strength ranking of each network type under the location.

Step S53: The non-access layer determines that the network type with the strongest signal strength is the target network type for the network search.

Through the solution of the embodiment of the present application, the non-access layer can access the server through the wireless network to obtain the signal strength ranking of each network type of the UE under the current application parameters, and determine the network type with the strongest signal strength based on this The target network type of secondary search.

In the method for generating a web search list disclosed in an embodiment of the present application, the non-access layer needs to determine, based on the network access information, the target network that the UE searches during the web search process when the UE communicates through various network types. This operation can be achieved in various ways.

In one of the modes, the non-access layer determines the target network searched during the network search process when the UE communicates through various network types based on the network access information, including:

The non-access layer uses the EHPLMN corresponding to the first network type in the network access information as the target network searched during the network search process when the UE communicates through the first network type.

The network access information includes the equivalent home network EHPLMN of the UE and the network type corresponding to the EHPLMN, so that the target network searched during the network search when communicating through each network type can be determined accordingly .

For example, if the EHPLMN in the network access information of the UE includes: 46000, 46002, 46007, and 46001, and the corresponding network types of 46000, 46002, and 46007 include various types of networks of China Mobile, namely GSM, TD-SCDMA and The network type corresponding to TD-LTE, 46001 is the network type supported by the leased China Unicom equipment, that is, GSM, and the first network type is GSM. When the UE communicates through the first network type, the network search process The target networks searched in are 46000, 46002, 46007, and 46001. When the first network type is TD-SCDMA, when the UE communicates through the first network type, the target network searched during the network search is 46000, 46002 and 46007. When the first network type is TD-LTE, when the UE communicates through the first network type, the target networks searched during the network search are 46000, 46002, and 46007.

Or, in another way, the network access information further includes a disabled network FPLMN of the UE and a network type corresponding to the FPLMN, where FPLMN and EHPLMN are usually set in a list. In this case, when the non-access layer determines the UE to communicate through various network types based on the network access information, it usually removes the list of FPLMN and EHPLMN when searching for the target network in the network search process The included FPLMN part, and then, determine the coincidence network of FPLMN and EHPLMN, and use the coincidence network and EHPLMN as the target network to be searched during the network search process when the UE communicates through various network types.

Through the above scheme, the coincident network of FPLMN and EHPLMN can be used as the target network to be searched during the network search process.

Correspondingly, this application discloses another embodiment. Referring to the schematic workflow diagram shown in FIG. 8, this embodiment of the present application discloses a web search method. The web search method includes the following steps:

Step S61: The access layer in the user equipment UE obtains a search network list, where the search network list contains the correspondence between the network type and the target network. The target network is when the UE communicates through each network type. The network to be searched during the web search.

Among them, the access layer can obtain the search list generated by the non-access layer through interaction with the non-access layer.

The network search list includes the correspondence between the network type and the target network. The target network is a network that needs to be searched during the network search process when the UE communicates through each network type. For example, when the UE communicates through the GSM network type, the target networks searched during the network search include 46000, 46002, 46007, and 46001. When the UE communicates through the TD-SCDMA network type, the search network The target networks searched during the process include 46000, 46002, and 46007. When the UE communicates via the TD-LTE network type, the target networks searched during the network search include 46000, 46002, and 46007. The list contains the correspondence between 46000, 46002, 46007 and 46001 and GSM, the correspondence between 46000, 46002 and 46007 and TD-SCDMA, and the correspondence between 46000, 46002 and 46007 and TD-LTE.

Step S62: The access layer determines the target network type of the network search.

Wherein, the access layer may determine the target network type of this network search in the same manner as the non-access layer determines the target network type.

Specifically, when the access layer obtains the search list for the first time after the UE is turned on, the access layer may obtain the last application of the UE during the last startup process by querying the usage log of the UE The network type of the communication network of the Internet, and the last time the UE was turned on, the network type of the communication network that was last applied is the target network type of the network search.

In other words, the target network type of this search can be determined through the historical usage of the UE. For example, if the search network list is generated for the first time after the UE is turned on, and by querying the usage log of the UE, it is determined that the last time the UE was turned on, the network type of the communication network last applied is TD -SCDMA, then the non-access layer determines that the target network type for this search is TD-SCDMA. That is to say, when generating the network search list for the first time after the UE is turned on, the target network type of the network search is determined according to the communication network last applied by the UE during the last startup process.

Alternatively, the access layer may determine the target network type for this network search according to the received network switching operation.

Among them, the network switching operation received by the access layer can indicate the target network type of the network search, for example, the network switching operation is used to make the display of the UE display multiple network types, and select a certain network type from As the target network type. After receiving the network switching operation, the access layer determines the target network type of the network search based on the network switching operation.

Alternatively, the access layer obtains the preset priorities corresponding to the various network types, and then determines that the network type with the highest priority is the target network type for the current network search. When the network type with the highest priority is searched and combined When the network search fails, the access layer selects other network types in turn as the target network type for this network search based on the priority levels of the respective network types.

In this method, the user can set the priority corresponding to each network type in advance. In this case, the non-access layer determines the target network type according to the set priority. Specifically, the non-access layer determines that the network type with the highest priority is the target network type for this network search. If the access layer fails to search the network in this case, the non-access layer selects the priority after The network type with the highest priority is the target network type for this search. That is to say, the scheme selects the target network type in turn according to the preset priority of each network type.

Alternatively, after receiving the network switching operation, the access layer obtains the application parameters of the UE, the application parameters include: address and/or time; then, the access layer is based on the application parameters of the UE, and the preset The correspondence between the application parameters and the priority of the network type determines the priority of each network type; finally, the access layer determines the network type with the highest priority as the target network type for this network search.

In this method, the access layer obtains the application parameters of the UE, and based on the correspondence between the application parameters of the UE and the preset application parameters and the priority of the network type, determines the priority of each network type and sets the highest priority Is used as the target network type for this search.

Alternatively, after receiving the network switching operation, the access layer obtains the application parameters of the UE, the application parameters include: address and/or time; when the UE is connected to the wireless network, the access layer obtains by accessing the server Under the application parameters, the signal strength of each network type is sorted; the access layer determines the network type with the strongest signal strength as the target network type for this search.

In this method, the access layer can access the server through the wireless network to obtain the signal strength ranking of the various network types of the UE under the current application parameters, and determine the network type with the strongest signal strength as the target of this network search. Network Type.

Of course, the access layer can also determine the target network type of the network search in other ways, which is not limited in the embodiment of the present application.

Step S63: The access layer determines the target network for the current network search and performs a network search operation based on the target network type and the network search list.

According to the solution disclosed in the embodiment of the present application, the network search list obtained by the access layer contains the correspondence between the network type and the target network. The target network is the network search process when the UE communicates through each network type. For the network that needs to be searched, the access layer can determine the target network type of this search, and then determine the target network of this search and perform the search operation based on the target network type and the search list.

In this case, the access layer can determine the target network to be searched according to the network type when searching according to the network search list, thereby avoiding searching for unsupported communication networks and reducing the need for the search process Time, further speed up the network, improve network efficiency, and improve user experience.

Further, in the embodiment of the present application, after the access layer determines the target network of the current network search and searches the network, the method further includes:

Among them, m is a preset positive integer, for example, m can be set to 5, then 5 consecutive network search operations have failed, the access layer can re-determine the target network, so as to search through the re-determined target network .

For example, if the access layer determines that the target network type is TD-LTE, but the m network search operations for each network corresponding to TD-LTE fail, the target network can be re-determined as TD-SCDMA, and the network search list , Determine the target network corresponding to TD-SCDMA, and perform the corresponding network search operation.

Another embodiment of the present application discloses a web search method. Referring to the schematic workflow diagram shown in FIG. 9, the web search method disclosed in the embodiment of the present application includes the following steps:

Step S71: The access layer in the user equipment UE obtains a network search list, where the network search list includes the target network corresponding to the target network type of the network search.

In this case, the non-access layer determines the target network type of the current network search and obtains a split search network list, where the split search network list includes the target network corresponding to the target network type. The access layer obtains the split search list by interacting with the non-access layer.

For example, if the non-access layer determines that the target network type for this network search is TD-SCDMA, the network search list obtained by the access layer includes the target network corresponding to the network type TD-SCDMA.

Step S72: The access layer performs a network search operation based on the network search list.

Further, in the embodiment of the present application, after the access layer performs a network search operation based on the network search list, the method further includes:

Where n is a preset positive integer, for example, n can be set to 5.

For example, the target network type for this search is TD-LTE, but the n times of network search operations for each network corresponding to TD-LTE have failed, indicating that under the current circumstances, the search list obtained through step S71 is performed. The network search cannot be successful. The access layer can re-acquire the network search list through interaction with the non-access layer. For example, the network search list including each network corresponding to TD-SCDMA can be obtained, and the network search operation can be performed again.

Through the above solution, the access layer can re-acquire the web search list and perform web search according to the re-acquired web search list.

Correspondingly, in another embodiment of the present application, an apparatus for generating a web search list is disclosed, wherein the apparatus for generating a web search list is provided in a non-access layer of a UE.

The split search network list contains the target network corresponding to the target network type, and the split network The search network list is transmitted to the access layer, so that the access layer can search the network according to the split search network list.

Wherein, the first processor determines the target network type of this search, including:

or,

Further, the target network type of the network search can be determined based on the application parameters of the UE. In this case, the first processor determines the target network type for this search, including:

The first processor determines that the network type with the highest priority is the target network type for the network search.

Alternatively, the first processor determines the target network type for this search, including:

Correspondingly, an embodiment of the present application discloses a network search device, which is usually provided in the access layer of the UE. Referring to the schematic structural diagram shown in FIG. 11, the network search device includes: a second memory 210 and a Second processor 220.
