Description

Cell determination method, equipment and system

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a cell determination method, device and system.

Background

At present, private network coverage can be provided for User Equipment (UE) moving at a high speed, public network coverage is provided for UE moving at a low speed, and in some regions, there are both public network coverage and private network coverage.

Generally, the UE may select a suitable cell to camp on based on its moving speed. Specifically, if the UE determines that the UE is a high-speed moving UE, the UE may preferentially select a private network cell (i.e., a cell for performing special deployment and parameter optimization for the high-speed moving UE) to camp on; if the UE determines that the UE is a low-speed moving UE, the UE may select a public network cell (i.e., a cell other than a cell for special deployment and parameter optimization for a high-speed moving UE) to camp on. For example, taking UE as UE on a high-speed train as an example, when the high-speed train runs, the UE may determine that it is a UE moving at a high speed, so as to select a private network cell to camp on; when the high-speed train stops at a station, the UE determines that the high-speed train is the UE moving at a low speed, so that a public network cell is selected to reside; when the high-speed train runs again, the UE determines that the high-speed train is the UE moving at a high speed, and accordingly the private network cell is selected to reside.

However, for a UE that is always on a high-speed train, if the above cell selection procedure is followed, the UE's resident network (e.g., private network and public network) may be changed back and forth, resulting in higher power consumption of the UE and possibly missed paging.

In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of processing units means two or more processing units, and the like.

The following first explains nouns and/or terms in the embodiments of the present invention.

A first wireless local area network: for providing wireless local area network services to a first type of UE, such as a UE located in a high-speed rail train.

A first network: for providing cellular network services to UEs of the first type.

The second wireless local area network: refers to a wireless local area network detected or accessed by the UE.

A second network: for providing cellular network services to UEs of a second type (UEs other than the first type).

In an embodiment of the present invention, the first wireless local area network may be a wireless local area network on a specific vehicle, for example, a high-speed train. The second wireless local area network is a wireless local area network detected or accessed by the UE. The first network may be a private network (i.e., a cellular network that serves the first type of UE). The second network may be a public network (i.e., a cellular network serving a second type of UE). The first type of UE may be a UE located inside a high-speed train, and the second type of UE may be a UE located outside the high-speed train.

The embodiment of the invention provides a cell determination method, equipment and a system, which can acquire first information and second information, wherein the first information comprises first sub information, the first sub information is used for indicating a first wireless local area network, the first wireless local area network is a network for providing service for first-class UE, the second information is used for indicating a second wireless local area network, and the second wireless local area network is a wireless local area network detected or accessed by the UE; and determining a target cell to be resided according to the first information and the second information. Through the scheme, since the embodiment of the invention can accurately determine whether the UE is the first type UE according to the information (i.e. the first information, for example, the information of the wireless local area network in the high-speed train) of the wireless local area network serving the first type UE (e.g. the UE located in the high-speed train) and the information (i.e. the second information) of the wireless local area network detected or accessed by the UE, the embodiment of the invention can accurately select a proper cell to camp on for the UE according to the determination result. For example, if it is determined that the UE is a first type UE, a private network cell may be selected for the UE to camp on; if the UE is determined not to be the first type of UE, a public network cell residence may be selected for the UE. Therefore, when the UE is the first type UE, the embodiment of the invention can reduce the power consumption of the UE and avoid the missed paging of the UE because the resident cell of the UE can be prevented from changing back and forth between the private network cell and the public network cell.

The cell determination method, the cell determination equipment and the cell determination system provided by the embodiment of the invention can be applied to a communication system. Fig. 1 illustrates an architecture diagram of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system may include a UE 01 and a network device 02. Wherein, the connection between the UE 01 and the network device 02 can be established.

It should be noted that, in the embodiment of the present invention, the UE 01 and the network device 02 shown in fig. 1 may be in wireless connection.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core Network devices via a Radio Access Network (RAN). The UE may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, that exchanges speech and/or data with the RAN, such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and so on. A UE may also be referred to as a User Agent (User Agent) or a terminal device, etc.

A network device is a device deployed in a RAN for providing wireless communication functionality for a UE. In the embodiment of the present invention, the network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices that function as base stations may differ. For example, in a 5G system, it may be referred to as a 5G base station (gNB); in a fourth Generation wireless communication (4-Generation, 4G) system, such as a Long Term Evolution (LTE) system, it may be referred to as an evolved NodeB (eNB); in a third generation mobile communication (3G) system, it may be referred to as a base station (Node B). As communication technology evolves, the name "base station" may change.

The method, device and system for determining a cell according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a cell determination method, which may be applied in a scenario where a UE determines a cell to camp on (e.g., a private network cell or a public network cell). As shown in fig. 2, the cell determination method may include S201-S204 described below.

S201, the network equipment sends first information.

The first information may be used for the UE to determine a target cell to camp on, and the first information may include first sub-information, where the first sub-information may be used to indicate a first wireless local area network, and the first wireless local area network is a network that provides services for the first type of UE.

In the embodiment of the present invention, the first UE may be a UE located in a specific vehicle (for example, a high-speed train, a motor train, or another vehicle capable of moving at a high speed). For convenience of explanation, the specific vehicle is a high-speed train as an example.

In the embodiment of the invention, the network equipment can be network equipment configured along a high-speed railway. The network device may serve a first type of UE (e.g., a UE located within a high-speed rail train). Specifically, the network device may send a broadcast message (including the first information) in real time or periodically, in which case, the UE receiving the broadcast message may obtain the first information from the broadcast message, and further may determine whether the UE is the first type UE by using the first information (e.g., the first sub-information therein). Further, if the UE determines that the UE is the first type of UE, the UE may select a private network cell to camp on; if the UE determines that the UE is not the first type of UE, the UE can select a public network cell to camp on. The specific implementation manner of determining, by the UE, whether the UE is the first type UE according to the first information will be described in detail below, which is not described herein again.

In the embodiment of the invention, when the UE determines that the UE is the first type UE, the UE can preferentially select the private network cell to reside. That is, the UE may first select a private network cell to camp on, and when the UE does not select a suitable private network cell, the UE may also select a public network cell to camp on.

Optionally, in the embodiment of the present invention, the step S201 may be specifically implemented by the step S201a described below.

S201a, the network device sends a broadcast message, and the broadcast message comprises first information.

In the embodiment of the invention, after the UE receives the broadcast message sent by the network equipment, the UE can acquire the first information from the broadcast message.

Optionally, in this embodiment of the present invention, the first wireless local area network may be a wireless local area network (Wi-Fi network) based on a wireless fidelity (Wi-Fi) technology, or may be a wireless local area network based on bluetooth

The wireless local area network (hereinafter referred to as bluetooth network) of the technology may also be any other wireless local area network that meets the actual use requirement, and may specifically be determined according to the actual use requirement, and the embodiment of the present invention is not limited.

Specifically, assuming that the first wireless local area network is a Wi-Fi network, the wireless network device for providing the Wi-Fi network may be a wireless router disposed in a high-speed train, and the wireless router may provide a Wi-Fi network service for the UE located in the high-speed train. For example, the first wireless local area network may be a Wi-Fi network located in a high-speed train as described above, and the Wi-Fi network may be used to provide wireless local area network services for a first type of UE (e.g., a UE located in a high-speed train).

Optionally, in an embodiment of the present invention, the first sub-information may be an identifier of a first wireless local area network (hereinafter, referred to as a first wireless local area network identifier). Specifically, the first sub information may include at least one of: a Media Access Control (MAC) address of the first wlan, a name of the first wlan, a wireless network identifier of the first wlan, and a Service Set Identifier (SSID) of the first wlan. It should be understood that the first sub-information is only an exemplary list, and does not limit the embodiment of the present invention, and may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

For example, in the case that the first wireless local area network is a Wi-Fi network, the first sub-information may include a first Wi-Fi network identifier for indicating the Wi-Fi network. For example, the first Wi-Fi network identification can be at least one of a MAC address of a Wi-Fi network, a Wi-Fi network name, and an SSID of the Wi-Fi network.

S202, the UE acquires first information.

In the embodiment of the invention, the UE can receive the first information sent by the network equipment. Specifically, the UE may receive a broadcast message (including the first information) sent by the network device, and may obtain the first information from the broadcast message after receiving the broadcast message sent by the network device. Further, the first information may include first sub information (the first sub information may be used to indicate the first wireless local area network), so that the UE may obtain the first sub information from the first information.

S203, the UE acquires second information.

The second information may be used to indicate a second wireless local area network, where the second wireless local area network is a wireless local area network detected or accessed by the UE.

In the embodiment of the present invention, the UE may automatically detect (or access after detecting) the wlan within the area where the UE is located in real time or periodically, or may trigger to detect (or access after detecting) the wlan within the area where the UE is located by the user. Further, after the UE detects a second wireless local area network within the area where the UE is located, the UE may acquire second information indicating the second wireless local area network.

Optionally, in this embodiment of the present invention, the second information may be an identifier of a second wireless local area network (hereinafter, referred to as a second wireless local area network identifier). Specifically, the second information may include at least one of the following: the MAC address of the second wireless local area network, the name of the second wireless local area network, the wireless network identifier of the second wireless local area network and the SSID of the second wireless local area network. It should be understood that the second information is only an exemplary list, and does not limit the embodiment of the present invention, and may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

For example, in the case that the second wireless local area network is a Wi-Fi network, the second information may include a second Wi-Fi network identifier for indicating the Wi-Fi network. For example, the second Wi-Fi network identification can be at least one of a MAC address of the Wi-Fi network, a Wi-Fi network name, and an SSID of the Wi-Fi network.

It is to be understood that, in the embodiment of the present invention, when the first information and the second information each include one item of information, the first information and the second information may be the same or different. When the first information and the second information both include at least two items of information, the first information and the second information may be completely the same, may be partially the same, or may be completely different.

It should be noted that the execution sequence of S202 and S203 may not be limited in the embodiment of the present invention. That is, in the embodiment of the present invention, S202 may be executed first, and then S203 may be executed; or executing S203 first and then executing S202; s202 and S203 may also be performed simultaneously. It is to be understood that fig. 2 illustrates the steps of executing S202 and then executing S203.

S204, the UE determines a target cell to be resided according to the first information and the second information.

In the embodiment of the invention, after the UE acquires the first information and the second information, the UE can determine whether the UE is the first type UE according to the first information and the second information, so that the UE can determine whether a cell where the UE is to reside is a private network cell or a public network cell. Specifically, in a case that the UE is determined to be a first type of UE (for example, it may be understood that the UE is located in a high-speed train), the UE may determine that a cell to be camped on is a private network cell; in the case that it is determined that the UE is not the first type of UE, the UE may determine that the cell to camp on is a public network cell.

It should be noted that, in the embodiment of the present invention, the private network cell may be a cell providing private network coverage for a first type of UE, and the public network cell may be a cell providing public network coverage for a second type of UE.

In the embodiment of the present invention, the UE may determine whether the UE is the first type UE according to the identifier of the wireless local area network acquired by the UE and the identifier of the wireless local area network detected (or accessed) by the UE. If the UE determines that the UE is the first type of UE, the UE can select a private network cell to reside; if the UE determines that the UE is not the first type of UE, the UE can select a public network cell to camp on. Therefore, the first type of UE can continuously reside in the private network cell, and even if the high-speed train stops temporarily but the UE is still positioned in the high-speed train, the first type of UE can still continuously reside in the private network cell without the problem that the resident cell of the first type of UE changes back and forth between the private network cell and the public network cell.

Optionally, in the embodiment of the present invention, in combination with fig. 2, as shown in fig. 3, S204 may be specifically implemented by S204a and S204b described below. Alternatively, S204 may be specifically realized by S204a and S204c described below.

S204a, the UE determines whether the first sub information and the second information match.

In the embodiment of the present invention, after acquiring the first information and the second information, the UE may compare the first sub information in the first information with the second information to determine whether the first sub information is matched with the second information.

It should be noted that, in the embodiment of the present invention, when the first sub information includes at least one first wireless local area network identifier and the second information includes at least one second wireless local area network identifier, if the at least one second wireless local area network identifier in the second information is the same as the at least one first wireless local area network identifier in the first sub information, the UE may determine that the first sub information is matched with the second information; if any one of the second wlan identities in the second information is different from any one of the first wlan identities in the first sub-information, the UE may determine that the first sub-information is not matched with the second information.

In the embodiment of the present invention, taking an example that the specific vehicle is a high-speed rail train, the first sub-information is an identifier of a first Wi-Fi network, and the second information is an identifier of a second Wi-Fi network, if the UE determines that the identifier of the second Wi-Fi network is the same as the identifier of the first Wi-Fi network, the UE may determine that the first sub-information is matched with the second information, so that the UE may determine that the UE is a first type of UE (for example, it may be understood that the UE is located in the high-speed rail train). If the UE determines that the identity of the second Wi-Fi network is different from the identity of the first Wi-Fi network, the UE may determine that the first sub-information does not match the second information, and thus the UE may determine that it is not a first type of UE (e.g., may understand that the UE is not located in a high-speed train).

In this embodiment of the present invention, if the UE determines that the first sub information matches the second information, the UE may continue to perform S204b described below; if the UE determines that the first sub information does not match the second information, the UE may proceed to S204c described below.

S204b, the UE determines a target cell from the first network.

In the embodiment of the present invention, when the UE determines that the first sub-information matches the second information, the UE may determine that the first sub-information is the first type of UE, and then the UE may determine the target cell from a first network, where the first network is a network providing services for the first type of UE, and for example, the first network may be a private network cell.

S204c, the UE determines the target cell from the second network.

In the embodiment of the present invention, when the UE determines that the first sub-information does not match the second information, the UE may determine that the UE is not a first type of UE, and further, the UE may determine a target cell from a second network, where the second network is used to provide services for a second type of UE other than the first type of UE, for example, the second network is a public network cell.

In the embodiment of the invention, a specific vehicle is taken as a high-speed train as an example, when the high-speed train runs, as the UE can be determined to be the first type of UE (namely the UE is positioned in the high-speed train), the UE can be selected to reside in a private network cell; when the high-speed train stops at the station and the UE is still located in the high-speed train, the UE can still continuously reside in the private network cell because the UE can determine that the UE is the first type UE. The UE can accurately determine the residence of the cell where the UE is to reside, so the embodiment of the invention can avoid the problem that the residence cell of the UE in the train changes back and forth between the private network cell and the public network cell because the high-speed rail train stops at the station temporarily in the running process, thereby reducing the power consumption of the UE and avoiding the missed paging of the UE.

Optionally, in the embodiment of the present invention, in the method shown in fig. 2 and fig. 3, the first sub information is taken as the network device to be sent to the UE as an example. In practical implementation, the first sub-information may also be pre-stored in the UE by a manufacturer of the UE. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in the embodiment of the present invention, when the first sub information is pre-stored in the UE by a manufacturer of the UE, the UE may update the pre-stored first sub information in the UE according to a message sent by the manufacturer.

The cell determining method provided by the embodiment of the present invention may accurately determine whether the UE is the first type UE according to the information (i.e., the first information, for example, the information of the wireless local area network in the high-speed train) of the wireless local area network that provides services for the first type UE (e.g., the UE located in the high-speed train) and the information (i.e., the second information) of the wireless local area network that the UE detects or accesses, and therefore, according to the determination result, may accurately select a suitable cell for the UE to camp on. For example, if it is determined that the UE is a first type UE, a private network cell may be selected for the UE to camp on; if the UE is determined not to be the first type of UE, a public network cell residence may be selected for the UE. Therefore, when the UE is the first type UE, the embodiment of the invention can reduce the power consumption of the UE and avoid the missed paging of the UE because the resident cell of the UE can be prevented from changing back and forth between the private network cell and the public network cell.

Optionally, in this embodiment of the present invention, the first information sent by the network device may further include a preset threshold in addition to the first sub-information. The preset threshold may be a preset threshold for measuring signal quality of the second wireless local area network. Specifically, the preset threshold may be used to measure the quality of the signal of the second wlan, which may be used as an auxiliary condition for determining whether the UE is the first type of UE.

It is to be understood that, in practical implementation, the preset threshold may also be pre-stored in the UE by the manufacturer of the UE.

It should be noted that the signal quality may be a signal-to-noise ratio of the signal, i.e. a ratio between a signal strength of the useful signal and a signal strength of the interference signal. It will be appreciated that the signal quality can be measured in terms of signal strength.

Optionally, in the embodiment of the present invention, the UE may determine whether the UE is the first type UE according to the identifier of the wireless local area network and the signal quality of the wireless local area network.

For example, in conjunction with fig. 2, as shown in fig. 4, S204 may be implemented by S204d, S204e, and S204g, which are described below. Or the above S204 may be specifically realized by S204d, S204e, and S204f described below. Alternatively, S204 may be specifically realized by S204d and S204f described below.

S204d, the UE determines whether the first sub information and the second information match.

For the description that the UE determines whether the first sub information and the second information are matched in S204d, reference may be specifically made to the related description in S204a, which is not described herein again.

In this embodiment of the present invention, if the UE determines that the first sub information matches the second information, the UE may continue to perform S204e described below; if the UE determines that the first sub information does not match the second information, the UE may proceed to S204f described below.

S204e, the UE determines whether the signal quality of the second wireless local area network is greater than or equal to a preset threshold.

In this embodiment of the present invention, if the UE determines that the signal quality of the second wlan is greater than or equal to the preset threshold (indicating that the signal quality of the second wlan is better), the UE may continue to perform S204g described below; if the UE determines that the signal quality of the second wlan is less than the predetermined threshold (indicating poor signal quality of the second wlan), the UE may continue to perform S204f described below.

S204g, the UE determines a target cell from the first network.

For the description that the UE determines the target cell from the first network in S204g, reference may be specifically made to the related description in S204b, which is not described herein again.

S204f, the UE determines the target cell from the second network.

For the description that the UE determines the target cell from the second network in S204f, reference may be specifically made to the related description in S204c, which is not described herein again.

In this embodiment, if the UE determines that the first sub-information is matched with the second information and determines that the signal quality of the second wireless local area network detected or accessed by the UE is greater than or equal to the preset threshold, the UE may determine that the UE is the first type of UE, and further, the UE may determine that the target cell where the UE is to camp is a private network cell, so that the UE may determine that the target cell is camped from the private network cell (that is, the UE performs the above S204 g). If the UE determines that the first sub-information is matched with the second information and that the signal quality of the second wireless local area network detected or accessed by the UE is smaller than the preset threshold, the UE may determine that the UE is not the first type of UE (for example, the second type of UE), and then the UE may determine that the target cell where the UE is to camp is a public network cell, so that the UE may determine that the target cell is camped from the public network cell (i.e., the UE performs the above S204 f).

In the embodiment of the present invention, the UE may determine whether the UE is located in a specific vehicle more accurately by using the first sub-information and the preset threshold, and further may determine whether a target cell where the UE is to reside is a private network cell or a public network cell more accurately, even though the UE may be fixedly camped in one network (specifically, may be different cells in one network). Therefore, the resident network of the UE is prevented from changing back and forth between the private network and the public network, the power consumption of the UE can be reduced, and the missed paging of the UE can be avoided.

In this embodiment of the present invention, the first information sent by the network device may further include at least one second sub-information. Each second sub information may be used to indicate one first cell, and at least one first cell indicated by the at least one second sub information is a cell in the first network. For example, the at least one second sub-information may be identities of at least one private network cell adjacent to the UE, where each identity is used to indicate one private network cell. Each Identifier may include a frequency point Identifier and a Physical Cell Identifier (PCI), that is, each Identifier may include a frequency point Identifier of a private network Cell and a PCI of the private network Cell.

It can be understood that, in the embodiment of the present invention, the first sub information in the first information may be sent by the network device or pre-stored in the UE. The preset threshold in the first information may be sent by the network device or pre-stored in the UE. At least one second sub-message of the first messages may be sent by the network device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in the embodiment of the present invention, in combination with fig. 3, as shown in fig. 5, the S204b may be specifically implemented by the following S204 h.

S204h, the UE determines a target cell from the at least one first cell according to the at least one second sub-message.

In an aspect, when the UE determines that the first sub-information matches the second sub-information, the UE may determine that the UE is a first type of UE, and then the UE may determine a target cell from at least one private network cell adjacent to the UE according to an identifier of the at least one private network cell.

On the other hand, in a case where the UE determines that the first sub-information does not match the second information, the UE may determine that it is a second type UE, and then the UE may determine a target cell from at least one public network cell adjacent to the UE.

It should be noted that fig. 5 is described in conjunction with fig. 3, and in a specific implementation, fig. 5 may also be implemented in conjunction with fig. 4.

In the embodiment of the invention, under the condition that the UE determines that the cell where the UE is to reside is the private network cell, the UE can directly select one private network cell from at least one private network cell which is indicated by the network equipment and is adjacent to the UE to reside, so that the UE can be prevented from searching and measuring the cell, and the power consumption of the UE is reduced.

Optionally, in this embodiment of the present invention, before the network device sends the first information to the UE, the network device may first obtain the first wlan identifier (i.e., an identifier of a wlan providing services for the first type of UE). In a possible implementation manner, the network device may obtain the first wlan identifier by collecting the identifier of the wlan reported by the UE. In another possible implementation manner, the network device may obtain the first wlan identifier by receiving an identifier of the wlan sent by another network device.

In the foregoing one possible implementation manner, for example, with reference to fig. 2, as shown in fig. 6, before S201, the cell determination method provided in the embodiment of the present invention may further include S205-S208 described below.

S205, the network equipment sends first indication information to the UE.

S206, the UE receives the first indication information.

The first indication information may be used to indicate the UE to report third information, where the third information is information of a wireless local area network detected by the UE.

S207, the UE sends third information to the network equipment according to the first indication information.

S208, after the network device receives the plurality of third information, the network device may determine the first sub information according to the plurality of third information.

The third information may be sent to the network device by a plurality of target UEs. Each third information may be information of a wireless local area network detected by one target UE. For example, each third information may be an identification of a wireless local area network detected by one target UE.

Optionally, in this embodiment of the present invention, the target UEs may be UEs whose moving speeds determined by evaluation using a Mobility State Estimation (MSE) algorithm are greater than or equal to a speed threshold, or UEs whose moving speeds determined by evaluation using other algorithms meeting actual usage requirements are greater than or equal to a speed threshold, which may be determined specifically according to actual usage requirements, which is not limited in this embodiment of the present invention.

For convenience of description, a UE moving at a speed greater than or equal to a speed threshold may be referred to as a UE moving at a high speed; accordingly, a UE moving at a speed less than the speed threshold may be referred to as a UE moving at a low speed. It is to be understood that the plurality of target UEs may be UEs moving at a high speed. The following describes in detail a specific implementation manner of the UE using the MSE algorithm to evaluate the UE moving at a high speed and the UE moving at a low speed.

Specifically, the UE may determine the moving speed of the UE by counting the number of cells that the UE passes through within a predetermined time. If the number of the UE crossing the cell in the preset time period is less than a preset threshold 1, the UE can be a UE moving at a low speed; if the number of the UE crossing the cell in the preset time period is larger than a preset threshold 1 and smaller than a preset threshold 2, the UE can be a medium-speed mobile UE; if the number of the crossed cells of the UE in the preset time period is greater than or equal to the preset threshold 2, the UE can be a UE moving at a high speed.

In the embodiment of the present invention, the network device may send the first indication information to a plurality of target UEs (for example, UEs moving at a high speed) to indicate the plurality of target UEs to report the third information. Accordingly, after receiving the first indication information, the plurality of target UEs may report the identities of the wireless local area networks detected by the plurality of target UEs to the network device. Furthermore, the network device may determine the first sub-information according to a plurality of third information reported by a plurality of target UEs.

Optionally, in this embodiment of the present invention, the target UEs may be the first type of UE.

In the embodiment of the present invention, since the third information is reported by the first type of UE, and the first type of UE is located in the specific transportation means, if the identifier of the wireless local area network detected by a certain UE is the same as the identifier of the wireless local area network issued by the network device (which is determined according to the third information), the UE can determine that the UE is the first type of UE, and therefore the UE can select the private network cell to reside.

It should be noted that, in the embodiment of the present invention, the network device that collects the identifier of the wlan reported by the UE may be the same as or different from the network device that broadcasts the first wlan identifier. That is, in the above possible implementation manner, the network device that collects the identifier of the wlan reported by the UE and the network device that broadcasts the first wlan identifier are the same network device; in another possible implementation manner, the network device that collects the identifier of the wlan reported by the UE and the network device that broadcasts the first wlan identifier are different network devices. In another possible implementation manner, in order to distinguish different network devices, in the embodiment of the present invention, a network device that broadcasts a first wlan identifier is referred to as a first network device (that is, network devices in each step of the foregoing embodiment are all the first network devices), and a network device that collects identifiers of wlans reported by UEs is referred to as a second network device.

In another possible implementation manner described above, for example, with reference to fig. 2 described above, as shown in fig. 7, before S201 described above, the cell determination method provided in the embodiment of the present invention may further include S209 to S210 described below.

S209, the second network device sends the first sub information to the first network device.

S210, the first network equipment receives the first sub information.

It can be understood that, in this embodiment, the first network device and the second network device are different network devices.

It should be noted that, in the embodiment of the present invention, a method for determining the first sub information by the second network device is similar to the method for determining the first sub information by the network device shown in fig. 6, which may specifically refer to the related description in the embodiment shown in fig. 6, and is not described here again to avoid repetition.

In the embodiment of the present invention, the network device may acquire the first wlan identifier by collecting the identifier of the wlan reported by the UE, or may acquire the first wlan identifier by receiving the identifier of the wlan sent by another network device, so that the flexibility of the network device in acquiring the first wlan identifier may be improved.

Optionally, in the embodiment of the present invention, after the UE determines the target cell to be camped on, the UE may camp on the target cell.

For example, with reference to fig. 2, as shown in fig. 8, after S204, the cell determining method provided in the embodiment of the present invention may further include S211.

S211, the UE resides in the target cell.

In the embodiment of the invention, after the UE determines the target cell to be resided, the UE can reside in the target cell. Specifically, the UE may camp on the private network cell when the UE determines that the target cell to be camped on is the private network cell; and under the condition that the UE determines that the target cell to be resided is the public network cell, the UE can reside in the public network cell.

In the embodiment of the invention, the UE can accurately determine the residence of the cell to be resided, so the embodiment of the invention can avoid the problem that the residence cell of the UE in the train changes back and forth between the private network cell and the public network cell because the high-speed rail train stops at the station temporarily in the running process, thereby reducing the power consumption of the UE and avoiding the missed paging of the UE.

For example, if it is determined that the UE is a first type UE, a private network cell may be selected for the UE to camp on; if the UE is determined not to be the first type of UE, a public network cell residence may be selected for the UE. Therefore, when the UE is the first type of UE, the UE provided by the embodiment of the invention can reduce the power consumption of the UE and avoid missed paging detection of the UE because the resident cell of the UE can be prevented from changing back and forth between the private network cell and the public network cell.

For example, if it is determined that the UE is a first type UE, a private network cell may be selected for the UE to camp on; if the UE is determined not to be the first type of UE, a public network cell residence may be selected for the UE. Therefore, when the UE is the first type UE, the embodiment of the invention can reduce the power consumption of the UE and avoid the missed paging of the UE because the resident cell of the UE can be prevented from changing back and forth between the private network cell and the public network cell.

For example, if it is determined that the UE is a first type UE, a private network cell may be selected for the UE to camp on; if the UE is determined not to be the first type of UE, a public network cell residence may be selected for the UE. Therefore, when the UE is the first type of UE, the UE provided by the embodiment of the invention can reduce the power consumption of the UE and avoid missed paging detection of the UE because the resident cell of the UE can be prevented from changing back and forth between the private network cell and the public network cell.
