Description

Networking mode switching method, device and system

Technical Field

The embodiment of the application relates to the field of communication, in particular to a networking mode switching method, device and system.

Background

The networking mode of the current network includes a Stand Alone (SA) and a Non Stand Alone (NSA). The SA mode is a network-based network independent networking. The NSA mode is a network mixed networking of a plurality of network standards. For example, in a fifth Generation mobile communication network (5th-Generation, 5G), the SA mode includes 5G network individual networking, and the NSA mode includes a fourth Generation mobile communication network (4th-Generation, 4G) network and 5G network hybrid networking.

The networks registered by the terminal in different networking modes are different, and the networks for service transmission are also different. For example, in a 5G network, in the NSA mode, the terminal cannot register in a 5G access technology (NR) network, and cannot use functions such as slicing and low latency of 5G. The terminal needs to use the high rate function of NR through a Dual Connection (DC) scheme, which may result in high power consumption. If the terminal is in the SA mode but the area has no NR network, the terminal may periodically search for the NR network, thereby generating higher power consumption and affecting services of other systems.

The terminal usually configures networking modes of various operators in advance, and when the terminal needs to use network functions, the network is searched and registered by using the pre-configured networking modes.

However, due to network coverage and the like, networking patterns may be different in different areas. If the terminal works in a preset networking mode, the networking mode of the terminal cannot be flexibly switched according to the networking modes in different areas. It may result in that the terminal cannot access the network in the networking mode corresponding to the area. Therefore, the problems of low access speed, increased power consumption of the terminal and the like are caused, and the network experience of the user is influenced.

Disclosure of Invention

The embodiment of the application provides a networking mode switching method, a networking mode switching device and a networking mode switching system, which are used for flexibly switching the networking mode of a terminal according to the networking mode of an area where the terminal is located.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a method for switching a networking mode, including: the terminal determines a networking mode supported by a target network of an area where the terminal is located; wherein, the networking mode includes: any one of a first networking mode and a second networking mode; and the terminal switches the networking mode of the terminal to the networking mode supported by the target network.

The application provides a networking mode switching method, and a terminal determines a networking mode supported by a target network in an area where the terminal is located. And by determining the networking mode of the target network in the area, a switching basis is provided for flexibly switching the networking mode of the terminal. Compared with the prior art, the networking mode of the terminal is consistent with the networking mode of the target network, so that the access speed of the terminal can be increased, the power consumption of network searching of the terminal is reduced, and the network experience of a user is improved.

In a possible implementation manner, the determining, by the terminal, a networking mode supported by a target network in an area where the terminal is located includes: a terminal receives a system message from a base station; the system message is used for determining a networking mode supported by a target network, and the target network is a network accessed by a base station; and the terminal determines the networking mode supported by the target network in the area where the terminal is located according to the system message. The terminal can simply, conveniently and accurately determine the networking mode supported by the target network through the system message.

In a possible implementation manner, the network type of the base station is a first network type; the system message comprises a first field, and the first field is used for determining that the network type of the target network is a first network type; the first network type is used for determining that a networking mode supported by a target network is a first networking mode; the terminal switches the networking mode of the terminal to the networking mode supported by the target network, and the method comprises the following steps: the terminal switches the networking mode of the terminal into a first networking mode. For example, taking the first network standard as a 4G network as an example, if it is determined that the target network supports the first networking mode (e.g., the NSA mode) through the first field, the terminal may determine to switch the networking mode to the first networking mode in order to avoid large power consumption caused by the terminal continuously searching for the 5G network.

In a possible implementation manner, the network type of the base station is a first network type; the terminal switches the networking mode of the terminal to the networking mode supported by the target network, and the method comprises the following steps: in case the first field is not included in the system message, the terminal receives a second field for indicating that the target network supports the second networking mode. And the terminal switches the networking mode of the terminal into a second networking mode. This facilitates the terminal to determine that the target network supports the second networking mode (e.g., SA mode) based on the second field, and to facilitate the terminal to enjoy the functions of the 5G network, thereby switching the networking mode of the terminal to the second networking mode.

In a possible implementation manner, the network type of the base station is a first network type; the terminal switches the networking mode of the terminal to the networking mode supported by the target network, and the method comprises the following steps: and under the condition that the system message does not comprise the first field, the terminal does not receive the second field, and the terminal switches the networking mode of the terminal into the first networking mode. Therefore, the networking mode of the terminal can be determined under the condition that the terminal does not receive the second field or the second field.

In a possible implementation manner, in a case that the system message does not include the first field, the terminal determines, according to whether the system message includes the third field and whether the second field is received, a networking mode supported by a target network in an area where the terminal is located.

The terminal may determine, based on a third field in the system message, that the network type of the target network is the second network type, and further determine that the target network supports the first networking mode.

In a possible implementation manner, the switching, by the terminal, the networking mode of the terminal to the networking mode supported by the target network includes: and the system message does not comprise the first field or the third field, the terminal receives the second field, and the terminal switches the networking mode of the terminal into the second networking mode. When the system message includes neither the first field nor the third field, the terminal may determine a second networking mode supported by the target network based on the second field.

In a possible implementation manner, the switching, by the terminal, the networking mode of the terminal to the networking mode supported by the target network includes: the system message does not comprise a first field and a third field, the terminal does not receive the second field, and the terminal switches the networking mode of the terminal into a first networking mode; and determining the network type of the target network to be a third network type. When the system message does not include the first field and the third field, if the terminal does not receive the second field, it is convenient to determine that the networking mode of the terminal needs to be switched to the first networking mode.

In a possible implementation manner, the network type of the base station is a second network type; the system message comprises a fourth field; the fourth field is used for forbidding the terminal to access the base station of the second network type; the terminal switches the networking mode of the terminal to the networking mode supported by the target network, and the method comprises the following steps: the terminal switches the networking mode of the terminal into a first networking mode. And under the condition that the fourth field indicates that the terminal is forbidden to access the base station of the second network type, the terminal can be preferentially switched into the first networking mode.

Detailed Description

In the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same or similar items having substantially the same function and action. For example, the first networking mode and the second networking mode are only for distinguishing different networking modes, and the order of the networking modes is not limited. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

Before describing the embodiments of the present application, the terms related to the embodiments of the present application will be explained as follows:

1. the second networking mode, which may also be referred to as (SA mode), refers to: and the control plane signaling of the terminal is transmitted to the core network through the NR base station. The terminal may be connected with the NR base station in the second networking mode (may be referred to as NR independent networking). Or in the second networking mode, the terminal may be connected to the NR base station, and the terminal may be connected to a Long Term Evolution (LTE) base station or an enhanced Long Term Evolution (LTE) base station.

The SA mode may include an Option 2 networking mode shown in fig. 1, an Option 4 networking mode shown in fig. 2(a), and an Option 4a networking mode shown in fig. 2 (b).

For example, as shown in fig. 1, in the Option 2 networking mode, a terminal accesses a 5G Core Network (NGC) through an NR base station. The terminal and the NR base station are connected through a user plane and a control plane, and the NR base station and the NGC are connected through the user plane and the control plane. The user plane connection may be used for transmitting user plane data, and the control plane connection may be used for transmitting control plane signaling. The control plane anchor point is located in the NR base station.

For example, the Option 4 networking mode shown in fig. 2(a) includes: the network node comprises a terminal, an eLTE base station and an NR base station which are communicated with the terminal, and an NGC which is communicated with the NR base station. The data splitting point is located at the NR base station. That is, the user plane data of the terminal interacts with the NGC through the NR base station. The control plane anchor point is located at the NR base station, i.e. the control plane signaling of the terminal is transmitted through the NR base station.

The terminal and the NR base station have control plane connection and user plane connection. The terminal and the eLTE have a user plane connection. And the eLTE base station and the NR base station have user plane connection. The NR base station and the NGC have a user plane connection and a control plane connection. In the Option 4 networking mode, for the uplink: the uplink user plane data of the terminal can be directly transmitted to the NR base station so as to be transmitted to the NGC by the NR base station. Or the uplink user plane data of the terminal is transmitted to the NR base station through the eLTE base station and then transmitted to the NGC through the NR base station. For the downlink: and the NGC transmits the downlink user plane data to the NR base station so as to be transmitted to the terminal by the NR base station, or the NR base station transmits the downlink user plane data to the terminal through the eLTE base station. In fig. 2(a), the NR base station transmits uplink control plane signaling from the terminal to the NGC. And the NR base station transmits the downlink control plane signaling from the NGC to the terminal.

Various versions of 3GPP in Long Term Evolution (LTE) and LTE-based evolution are new versions of UMTS using E-UTRA. The 5G communication system, New Radio (NR), is the next generation communication system under study. In addition, the communication system can also be applied to future-oriented communication technologies, and the technical solutions provided by the embodiments of the present application are all applied.

A terminal (terminal) is a device that provides voice and/or data connectivity to a user, e.g., a handheld device, a vehicle-mounted device, etc., with wireless connectivity. A Terminal may also be referred to as a User Equipment (UE), an Access Terminal (Access Terminal), a subscriber Unit (User Unit), a subscriber Station (User Station), a Mobile Station (Mobile Station), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), a Mobile device (Mobile Equipment), a User Terminal (User Terminal), a Wireless communication device (Wireless Terminal Equipment), a User Agent (User Agent), User Equipment (User Equipment), or a User device. The terminal may be a Station (STA) in a Wireless Local Area Network (WLAN), and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) Station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a terminal in a next Generation communication system (e.g., a Fifth-Generation (5G) communication Network) or a terminal in a future-evolution Public Land Mobile Network (PLMN) Network, and the like. Wherein, 5G may also be referred to as a new air interface.

As an example, in the embodiment of the present application, the terminal may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

In the embodiment of the present application, a base station is an entity that can be used to transmit or receive a signal and is used in cooperation with a terminal. For example, the ue may be an evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), or a relay station or an access point, or a vehicle-mounted device, a wearable device, and a base station in a future 5G network or a base station device in a future evolved PLMN network.

In addition, in the embodiment of the present invention, the base station provides a service for a cell, and the terminal performs wireless communication with the base station through a transmission resource (for example, a time domain resource, or a frequency domain resource, or a time frequency resource) used by the cell. The cell may be a cell corresponding to a base station, and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell). Here, the small cell may include: urban cell (metro cell), micro cell (microcell), Pico cell (Pico cell), femto cell (femto cell), etc., which have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

The future base station can be implemented by adopting a cloud radio access network (C-RAN) architecture. One possible way is to divide the protocol stack architecture and functionality of the legacy base station into two parts, one part being called a Central Unit (CU) and the other part being called a Distributed Unit (DU). As shown in fig. 7, CU parts of a plurality of base stations are integrated together to form a large-scale functional entity. Multiple DUs can be centrally controlled by one CU. As shown in fig. 7, the CU and the DU may be divided according to protocol layers of the wireless network, for example, functions of a Packet Data Convergence Protocol (PDCP) layer and a protocol layer (e.g., Radio Resource Control (RRC)) are provided in the CU. The protocol layers below the PDCP layer, such as Radio Link Control (RLC), Medium Access Control (MAC), and Physical layer (PHY), are provided in the DU.

It is understood that the division of the protocol layers shown in fig. 7 is only an example, and the division may also be performed in other protocol layers, for example, in the RLC layer, the functions of the RLC layer and the protocol layers above are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU. Alternatively, the functions are divided into some protocol layers, for example, a part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are provided in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU. The embodiments of the present application do not limit this.

In addition, with continuing reference to fig. 8, with respect to the architecture shown in fig. 7, the Control Plane (CP) and the User Plane (UP) of the CU may be separated and implemented by being divided into different entities, i.e. a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity), respectively.

In the above network architecture, data generated by a CU may be transmitted to a terminal through a DU. Or the data generated by the terminal may be transmitted to the CU through the DU. The DU may not parse the data and directly encapsulate the data through a protocol layer and transmit the encapsulated data to the terminal or CU. For example, data of the RRC or PDCP layer is finally processed into data of a physical layer (PHY) and transmitted to the terminal, or converted from received data of the PHY layer. Under this architecture, the data of the RRC or PDCP layer can also be considered to be transmitted by the DU.

In the above embodiment, the CU is divided into base stations in the RAN, and furthermore, the CU may also be divided into base stations in the core network CN, which is not limited herein.

When the above structure of CU-DU is adopted, the base station may be a CU node, or a DU node, or a RAN device including the functions of the CU node and the DU node.

Specifically, the one or more antennas 1115 may receive rf signals, and the receiver Rx of the transceiver 1113 is configured to receive the rf signals from the antennas, convert the rf signals into digital baseband signals or digital intermediate frequency signals, and provide the digital baseband signals or digital intermediate frequency signals to the processor 1111, so that the processor 1111 may further process the digital baseband signals or digital intermediate frequency signals, such as demodulation and decoding.

Fig. 10 is a schematic structural diagram of a terminal according to an embodiment of the present application. The structure of the terminal 101 can refer to the structure shown in fig. 10.

The terminal includes at least one processor 1211, at least one transceiver 1212, and at least one memory 1213. The processor 1211, the memory 1213 and the transceiver 1212 are coupled.

An antenna 1216 is coupled to the transceiver 1212, and an output device 1214 and an input device 1215 are coupled to the processor 1211.

The embodiment of the application provides a method for switching a networking mode, which is applied to a communication system shown in fig. 6. As shown in fig. 11, the method includes:

step 101, the terminal determines the networking mode supported by the target network of the area where the terminal is located. Wherein, the networking mode includes: any one of the first networking mode and the second networking mode.

Illustratively, the first networking mode is an NSA mode and the second networking mode is an SA mode.

The target network is a network to be accessed by the terminal, and comprises a base station and a core network.

And 102, the terminal switches the networking mode of the terminal into the networking mode supported by the target network.

Through step 102, the terminal may switch the networking mode of the terminal to the networking mode supported by the target network.

Specifically, the terminal determines that the networking mode supported by the target network is the first networking mode, and then the terminal switches the networking mode of the terminal into the first networking mode. And the terminal determines that the networking mode supported by the target network is the second networking mode, and then the terminal switches the networking mode of the terminal into the second networking mode.

Illustratively, if the networking mode supported by the target network is an NSA mode, the terminal switches the networking mode of the terminal to the NSA mode. In the NSA mode, the terminal can not execute the action of periodically searching the NR network, thereby reducing the power consumption of the terminal and avoiding the influence on other non-NR system services of the terminal.

Illustratively, if the networking mode supported by the target network is an SA mode, the terminal switches its networking mode to the SA mode. In the SA mode, the terminal may experience a network slicing function in the 5G network, new network characteristics such as low latency, and the like, and the terminal may experience high-rate service characteristics of the 5G network without Dual Connection (DC), thereby reducing power consumption of the terminal and greatly improving network experience of the user.

As a possible embodiment of the present application, with reference to fig. 11, as shown in fig. 12, a method provided in this embodiment of the present application further includes, before step 101:

and step 103, the base station sends a system message to the terminal. The system message is used for determining a networking mode supported by a target network, and the target network is a network accessed by the base station.

It should be understood that the base station in step 103 may be a base station to which the terminal accesses.

The network standard of the base station comprises any one of a first network standard and a second network standard. In the embodiment of the present application, the first network type is LTE, and the second network type is NR.

In one implementation manner of step 103, the terminal sets the network type of the base station with priority for access in advance. When the terminal is in the area to stay in the network, the terminal can be preferentially accessed to a base station with a preset network system.

Taking the base station in which the area includes both LTE and NR systems as an example, if the terminal is set to access the LTE base station preferentially. The terminal determines a base station list of the area (the base station list comprises both the LTE base station and the NR base station), and the terminal preferentially resides in the LTE base station.

After the terminal completes camping in the corresponding base station, the base station may send a system message to the terminal.

And 104, the terminal receives the system message from the base station.

Step 101 in the embodiment of the present application may be specifically implemented by the following method: and the terminal determines the networking mode supported by the target network in the area where the terminal is located according to the system message.

Since the network systems of the base stations are different, the meanings of the fields carried in the system messages are different, and the specific implementation of step 101 is different, the following description will be given respectively:

example 1), taking the network standard of the base station as the first network standard as an example:

as a possible embodiment, referring to fig. 12, as shown in fig. 13, the method provided in this embodiment further includes step 105 after step 104.

Step 105, the terminal determines whether the system message includes the first field.

The first field is used for indicating that the network type of the target network is a first network type; the first network type is used for determining that the networking mode supported by the target network is the first networking mode.

Illustratively, the system message includes a System Information Block (SIB) 1, and the SIB1 includes a cellaccesratedinfolist-5 GC field. The first field in the embodiment of the present application may be the cellAccess relatedInfoList-5GC field in the SIB 1.

Correspondingly, the first network type may be any one of the Option 5 networking mode, the Option 7a networking mode, or the Option 7x networking mode.

Since whether the first field is included in the system message affects the terminal to determine the networking mode supported by the target network, the following description will be separately presented:

case 1), the terminal determines that the system message includes the first field, which is a possible implementation manner of the present application, and step 101 in this embodiment of the present application may be implemented specifically by the following manner: the terminal determines that the networking mode supported by the target network is the first networking mode.

Specifically, the terminal reads the system message, determines that the SIB1 includes a cellaccesratedinfolist-5 GC field, and determines the type of the target network and the first network type according to the field. The terminal determines that the networking mode supported by the target network is the NSA mode.

Accordingly, step 102 may be specifically implemented by: the terminal switches the networking mode of the terminal into a first networking mode. That is, the terminal switches the networking mode of the terminal to the NSA mode.

Case 2), the terminal determines that the system message does not include the first field, then the method provided in this embodiment further includes step 106.

Step 106, the terminal determines whether the terminal receives the second field.

The second field is used to indicate that the target network supports the second networking mode.

Illustratively, the second field may be an (Interworking without N26interface indicator, IWK N26) field. The IWK N26 field is used to indicate that the target network supports 5G and 4G (i.e., LTE base station and NR base station) interworking (5G and 4G interworking refers to operations such as handover, reselection redirection, and the like between 5G and 4G), and since the SA mode may have 5G and 4G interworking, the terminal may further determine that the networking mode of the target network is the SA mode through the second field.

In an implementation manner of step 106, the second field is a field that is sent by the core network to the terminal through the LTE base station in the process of registering the terminal with the LTE base station.

In the case where the terminal determines that the system message does not include the first field, whether the terminal receives the second field also affects the networking mode supported by the terminal determining target network, so the following will be introduced separately:

case 2-1), the terminal determines that the second field is received, as a possible implementation manner of the present application, step 101 in this embodiment of the present application may be implemented specifically by the following manner: and the terminal determines that the networking mode supported by the target network is the second networking mode.

Specifically, if the terminal receives the IWK N26 field, the terminal determines that the networking mode supported by the target network is the SA mode.

Accordingly, step 102 may be specifically implemented by: and the terminal switches the networking mode of the terminal into a second networking mode. That is, the terminal switches the networking mode of the terminal to the SA mode.

Case 2-2), the terminal determines that the second field is not received, as a possible implementation manner of the present application, step 101 in this embodiment of the present application may be implemented specifically by the following manner: the terminal determines that the networking mode supported by the target network is the first networking mode.

If the terminal determines that the SIB1 does not include the cellAccessRelatedInfoList-5GC field, and does not receive the IWK N26 field, it indicates that the target network may not support the 5G and 4G interworking, and the networking mode of the target network is the NSA mode.

As another embodiment of the present application, the terminal may further determine the networking mode of the terminal according to whether the system message includes the third field, and a specific process is shown in fig. 13: the method provided by the embodiment of the present application further includes, after step 105 and before step 106:

step 107, the terminal determines whether the system message includes a third field.

Wherein the third field is used to determine that the network type of the target network is the second network type.

Illustratively, the third field is the upperLayerIndication field in SIB 2. The second network type is one of an Option3 networking mode, an Option 3a networking mode or an Option 3x networking mode.

After step 107, the terminal performs step 106.

In one implementation of step 106, after step 107, the terminal may register with the LTE base station first. During the process of registering the terminal with the LTE base station, the terminal may receive a second field sent by the core network through the base station.

In the case that the terminal determines that the system message includes the third field, whether the terminal receives the second field affects the networking mode supported by the terminal for determining the target network, and therefore the following description will be separately presented:

A) and the terminal determines that the system message comprises a third field and receives the second field.

As another possible implementation manner of the present application, step 101 in the embodiment of the present application may be specifically implemented by:

step 101, the terminal determines that the networking mode supported by the target network is a second networking mode.

In a possible implementation manner of step 101, if the terminal receives the IWK N26 field during the registration process with the LTE base station, at this time, the terminal determines the interoperation of the target networks 5G and 4G, and further, the terminal determines that the networking mode supported by the target network is the SA mode. At the moment, the terminal switches the networking mode of the terminal into an SA mode, the terminal disconnects with the LTE base station, searches the NR base station again, and initiates a registration process to the NR base station.

Correspondingly, step 102 in the embodiment of the present application may be specifically implemented by the following means: and the terminal switches the networking mode of the terminal into a second networking mode.

B) And the system message comprises a third field, and the terminal does not receive the second field.

As another possible implementation manner of the present application, step 101 in the embodiment of the present application may be specifically implemented by: the terminal determines that the networking mode supported by the target network is a first networking mode, and determines that the network type of the target network is a second network type.

Specifically, if the terminal does not receive the IWK N26 field during the registration process with the LTE base station, the terminal may determine that the target network does not support the 5G and 4G interworking, and does not have an SA network. The terminal determines that the network type of the target network is one of an Option3 networking mode, an Option 3a networking mode or an Option 3x networking mode according to the upperLayerIndication field in the SIB2, that is, the networking mode supported by the target network is the NSA mode. At this time, the terminal switches the networking mode of the terminal to the NSA mode and continues to register with the LTE base station.

Correspondingly, step 102 in the embodiment of the present application may be specifically implemented by the following means: the terminal switches the networking mode of the terminal into a first networking mode.

In the case where the terminal determines that the system message does not include the third field, whether the terminal receives the second field affects the networking mode supported by the terminal determining target network, and therefore the following description will be separately presented:

C) and the terminal receives the second field.

As another possible implementation manner of the present application, step 101 in the embodiment of the present application may be specifically implemented by the following manner: and the terminal determines that the networking mode supported by the target network is the second networking mode.

In one implementation manner of step 101, in a case that the system message does not include the third field, the terminal initiates a registration procedure to the LTE base station. The terminal receives the IWK N26 field in the process of registering to the LTE base station, and at the moment, the terminal determines that the current target network supports 5G and 4G interoperation, namely the networking mode supported by the target network is the SA mode. At this time, the terminal switches the networking mode of the terminal to the SA mode, searches the NR base station again, and initiates a registration process to the NR base station.

D) And the system message does not comprise the third field, and the terminal does not receive the second field.

As another possible implementation manner of the present application, step 101 in the embodiment of the present application may be specifically implemented by: the terminal determines that the networking mode supported by the target network is the first networking mode.

In addition, the terminal may also determine that the network type of the target network is a third network type.

Illustratively, the third network type is an LTE network.

In an implementation manner of step 101, if the IWK N26 field is not received in the process of registering the terminal to the LTE base station, the terminal determines that the target network may not support the 5G and 4G interoperation, at this time, the system message does not include the upperLayerIndication field, and the terminal determines that the network type of the target network is the LTE network. Since the target network does not include the NR base station, and the terminal periodically searches for the NR base station in the SA mode, the terminal needs to switch the networking mode of the terminal to the NSA mode, thereby preventing the terminal from frequently searching for the NR base station.

On the one hand, taking the terminal residing in the LTE base station as an example, the terminal may determine that the network type of the target network is one of an option 5 networking mode, an option7 networking mode, an option 7a networking mode, or an option 7x networking mode according to the cellaccesratedlnflisti-5 GC field in the SIB 1. Then, the terminal may determine that the networking mode of the target network is the NSA mode, and finally, the terminal switches the networking mode of the terminal to the NSA mode.

On the other hand, taking the case that the terminal resides in the LTE base station as an example, the terminal determines that the SIB1 does not include the cellaccesratedinfolist-5 GC field, the terminal further determines whether the SIB2 includes the superlayer indication field, and if the SIB2 includes the superlayer indication field, it indicates that the target network supports the NSA mode, so the terminal initiates a registration procedure to the LTE base station, and if the terminal receives the IWK N26 field from the core network during the registration procedure, the terminal may further search for an NR base station, and then the terminal determines that the networking mode of the target network is the SA mode, and the terminal switches the networking mode of the terminal to the SA mode. If the terminal does not receive the IWK N26 field in the registration process, the terminal switches the networking mode of the terminal to the NSA mode, and the terminal further confirms that the network type of the target network is one of an Option3 networking mode, an Option 3a networking mode or an Option 3x networking mode according to the upperLayerIndication field in the SIB 2.

If the SIB2 does not include the upperLayerIndication field, the terminal still initiates a registration process to the LTE base station, and if the terminal receives the IWK N26 field from the core network during the registration process, the terminal may also search for an NR base station, and then the terminal determines that the networking mode of the target network is the SA mode, and switches the networking mode of the terminal to the SA mode. If the terminal does not receive the IWK N26 field in the registration process, the terminal switches the networking mode of the terminal to the NSA mode, and the terminal determines that the network type of the target network is the LTE network.

Therefore, when the terminal resides in the LTE base station, the networking mode of the terminal can be flexibly switched through the specific field in the system message and the field received in the registration process, so that the networking mode of the terminal is matched with the networking mode of the network, and the network experience of the terminal is improved.

Example 2), taking the network standard of the base station as the second network standard, as shown in fig. 14 with reference to fig. 12, after step 104, the networking mode switching method further includes:

step 108, the terminal determines whether the system message includes the fourth field.

The fourth field is used for prohibiting the terminal from accessing the base station of the second network type (that is, prohibiting the terminal from registering in the base station of the second network type).

Illustratively, the system message includes a Master Information Block (MIB). A Barred (Barred) field may be included in the MIB.

In one implementation of step 108, the fourth field is a Barred field in the MIB. The Barred field is used to indicate that the terminal is prohibited from accessing the NR base station. In addition, the Barred field may also be used to indicate that the network type of the target network is the second network type.

On one hand, if the terminal determines that the system message includes the fourth field, as another possible implementation manner of the present application, step 101 in this embodiment of the present application may be implemented specifically by the following manner: the terminal determines that the networking mode supported by the target network is the first networking mode.

If the system message includes a Barred field, the terminal determines that the network type of the target network is one of an Option3 networking mode, an Option 3a networking mode or an Option 3x networking mode, and further determines that the networking mode supported by the target network is an NSA mode.

Specifically, the terminal determines that the networking mode supported by the target network is the NSA mode, and the terminal switches the networking mode of the terminal to the NSA mode.

On the other hand, if the terminal determines that the system message does not include the fourth field, as another possible implementation manner of the present application, step 101 in this embodiment of the present application may be specifically implemented by: and the terminal determines that the networking mode supported by the target network is the second networking mode.

If the Barred field is not included in the system message, the terminal can access the NR base station, the terminal determines that the network type of the target network is an Option 2 networking mode, an Option 4 networking mode or an Option 4a networking mode, and then the terminal determines that the networking mode supported by the target network is an SA mode.

Specifically, the terminal determines that the networking mode supported by the target network is the SA mode, and the terminal switches the networking mode of the terminal to the SA mode.

The embodiment of the application provides a networking mode switching method, and by taking the situation that a terminal resides in an NR base station as an example, the terminal determines whether a Barred field is included in a system message.

If the system message includes a Barred field, the terminal determines that the network type of the target network is one of an Option3 networking mode, an Option 3a networking mode or an Option 3x networking mode, and the terminal further determines that the networking mode supported by the target network is an NSA mode. And the terminal switches the networking mode of the terminal into the NSA mode.

If the Barred field is not included in the system message, the terminal determines that the network type of the target network is an Option 2 networking mode, an Option 4 networking mode or an Option 4a networking mode, and the terminal further determines that the networking mode supported by the target network is an SA mode. And the terminal switches the networking mode of the terminal into the SA mode.

Therefore, when the terminal resides in the NR base station, the networking mode of the terminal can be flexibly switched through a specific field in the system message. The networking mode of the terminal is matched with the networking mode of the network, and the network experience of the terminal is improved.

The embodiment of the application also provides a method for determining the networking mode supported by the target network through the network standard of the base station in the target network. With reference to fig. 11, as shown in fig. 15, the method provided in this embodiment of the present application further includes, before step 101:

and step 109, the terminal determines the selected PLMN for the terminal.

Taking manual network selection as an example, after receiving an instruction of manual network selection, the terminal searches for a network in an area where the terminal is located, determines at least one PLMN in the area, and determines a network system of a base station included in each PLMN in the at least one PLMN.

Step 110, the terminal determines the network type of the base station included in the PLMN.

Specifically, the terminal determines a network type of a base station included in each PLMN in at least one PLMN.

As shown in fig. 16, a network searching result display interface in the manual network searching process of the terminal provided in the embodiment of the present application is shown.

After searching the network, the terminal determines that the area includes three PLMN networks, namely PLMN1, PLMN2 and PLMN 3. The network system of the base station in the PLMN1 includes LTE, the network system of the base station in the PLMN2 includes LTE and NR, and the network system of the base station in the PLMN3 includes NR.

The terminal displays a network list of the three PLMNs. And the terminal determines to select the corresponding PLMN for the terminal according to the received PLMN list selection instruction.

After step 110, as another possible implementation manner of the present application, step 101 in the embodiment of the present application may be specifically implemented by: and the terminal determines the networking mode supported by the target network according to the network type of the base station included in the PLMN.

Specifically, the terminal determines the networking mode supported by the target network according to the network type of the base station in the PLMN determined in the network searching process.

Since the network system of the base station included in the PLMN affects the networking mode supported by the terminal for determining the target network, the following description will be separately introduced:

1) as another possible implementation manner of the present application, when the terminal determines that the network type of the base station in the PLMN includes the first network type but does not include the second network type, step 101 in this embodiment of the present application may be specifically implemented by the following manner: the terminal determines that the networking mode supported by the target network is a first networking mode or a second networking mode.

In an implementation manner of step 101, taking the PLMN selected for the terminal by the terminal as PLMN1 as an example, the terminal determines that only LTE base stations included in PLMN1 do not include NR base stations in the network searching process. And the terminal determines that the networking mode supported by the target network may be an SA mode or an NSA mode.

Accordingly, step 102 in the embodiment of the present application may be implemented as: the terminal keeps the networking mode of the current terminal.

The terminal keeps the current networking mode of the terminal from switching. Namely the terminal is currently in the NSA mode, the NSA mode is still kept; the terminal is currently in the SA mode, and the SA mode is still maintained.

In one implementation of step 102, the NR base station is not included in the PLMN1 for the area where the terminal determines to be located. If the terminal is in the SA mode currently, in order to reduce power consumption of the terminal, the terminal is in a static state or a jogging state (the motion amplitude is smaller than a preset value) within a first preset time period, and the terminal does not start the NR network searching function. And when the preset time is exceeded or the terminal moving distance is far, the terminal restarts the NR network searching function.

2) Determining network types of a base station in the PLMN at the terminal, wherein the network types comprise a first network type and a second network type; or when the network standard of the base station in the PLMN does not include the first network standard but includes the second network standard, as another possible implementation manner of the present application, step 101 in this embodiment of the present application may be specifically implemented by the following manner: and the terminal determines that the networking mode supported by the target network is the second networking mode.

In step 101, taking the PLMN selected by the terminal as PLMN2 as an example, the terminal determines that the PLMN2 includes an LTE base station and an NR base station in the network searching process.

Taking the PLMN selected for the terminal by the terminal determination as PLMN3 as an example, the terminal determines that the PLMN3 does not include an LTE base station but includes an NR base station in the network searching process.

When the terminal searches for a network, it is determined that the PLMN2 and the PLMN3 both include an accessible NR base station, and therefore if the target network is PLMN2 or PLMN3, the terminal determines that the networking mode of the target network is an SA mode.

Correspondingly, step 102 in the embodiment of the present application may be specifically implemented as: and the terminal switches the networking mode of the terminal into a second networking mode.

And under the condition that the terminal determines that the networking mode supported by the target network is the SA mode, the terminal switches the networking mode of the terminal into the SA mode.

According to the networking mode switching method provided by the embodiment of the application, the terminal determines the network system of the base station in each PLMN in the area according to the result of manual network searching, determines the networking mode of the target network according to the network system of the base station in the PLMN, and switches the networking mode of the terminal to the networking mode of the target network. If the terminal determines that the PLMN only includes the LTE base station and does not include the NR base station, the terminal determines that the networking mode supported by the target network may be an SA mode or an NSA mode, and the terminal maintains the current networking mode of the terminal. If the terminal determines that the PLMN comprises the LTE base station and the NR base station or the terminal determines that the PLMN does not comprise the LTE base station but comprises the NR base station, the terminal determines that the networking mode of the target network is the SA mode, and the terminal switches the networking mode of the terminal into the SA mode. Therefore, when the network is manually searched, the terminal can determine the networking mode supported by the target network through the selected network mode of the base station in the PLMN, and then flexibly switch the networking mode of the terminal. The networking mode of the terminal is matched with the networking mode of the network, and the network experience of the terminal is improved.

After step 102, normal use of the terminal is affected because the terminal may frequently switch between the first networking mode and the second networking mode. Therefore, after step 102, the method provided by the embodiment of the present application further includes:

and step 111, the terminal starts a suppression timer when the number of times of switching the networking mode of the terminal in the first time period is larger than a preset threshold value.

And the suppression timer is used for enabling the terminal to switch the networking mode of the terminal after the second time period.

Specifically, if the terminal is in a static state or a jogging state, the terminal determines that the number of times of switching the networking mode by the terminal is greater than a preset threshold value, the terminal starts a suppression timer, and the terminal is prohibited from switching the networking mode in a second time period.

For example, taking the first time period as T1 and the second time period as T2, if the number of times that the terminal switches the networking mode in the T1 time period is greater than a preset threshold, the terminal stops switching the networking mode in the T2 time period. The preset threshold value is not limited in the embodiment of the application.

In one implementation of the embodiment of the present application, the second time period T2 is located after the first time period. The second period T2 is a period adjacent to the first period T1 after the first period T1; or the second period T2 is a period not adjacent to the first period T1 after the first period T1.

It should be understood that step 111 may be located after step 102 in any one of fig. 11, 12, 13, 14, 15, or 17, and is exemplarily illustrated in fig. 13, 14, and 17 in the embodiment of the present application.

After step 102, after the terminal switches the networking mode, the network performance value of the terminal after switching the networking mode may become small, and therefore after step 102, the embodiment of the present application further provides a method for preventing the network performance value of the terminal after switching the networking mode from becoming small, as shown in any one of fig. 13, fig. 14, or fig. 17, the method further includes:

after the networking mode of the terminal is switched from the first mode to the second mode, the terminal determines whether the network performance value of the terminal in the second mode is smaller than the network performance value of the terminal in the first mode in step 112.

The first mode comprises a first networking mode, and the second mode comprises a second networking mode; alternatively, the first mode includes a second networking mode, and the second mode includes the first networking mode.

In one possible implementation, the network performance values include: any one or more of a data transmission rate, a registration condition of the terminal in the network, a power consumption value of the terminal, and a temperature value of the terminal.

It should be understood that the present application only exemplifies four network performance values, and the network performance values may also include other parameters in a specific application, which is not limited in the present application.

In case the terminal determines that the network performance value of the terminal in the second mode is smaller than the network performance value of the terminal in the first mode, the terminal performs step 113.

And 113, the terminal switches the networking mode of the terminal from the second mode to the first mode.

Specifically, after the terminal switches the networking mode, due to network failure, an excessive network load, or the like, or after the networking mode is switched, the power consumption value and/or the temperature value of the terminal are increased, and it may happen that after the networking mode is switched by the terminal, the network performance value of the terminal is smaller than the network performance value before the networking mode is switched. At this time, the terminal switches the networking mode back to the original networking mode.

In one implementation manner of the embodiment of the present application, after step 113, step 114 is further included.

Step 114, the terminal starts a suppression timer.

The role of the suppression timer in step 114 is similar to that of the suppression timer in step 111, and is not described in detail here.

It should be understood that step 112 is located after step 111 in fig. 13, 14 or 17, but step 111 and step 112 are independent of each other in the actual implementation. Step 111 may be performed before step 112, or may be performed after step 112, or step 111 and step 112 may be performed in parallel.

It should be understood that step 112, step 113, and step 114 may be located after step 102 in any one of fig. 11, fig. 12, fig. 13, fig. 14, fig. 15, or fig. 17, and are exemplarily illustrated in fig. 13, fig. 14, and fig. 17 in the embodiment of the present application.
