Background

In wireless communication, a base station may broadcast system information of a cell, so that a terminal device may access a corresponding cell based on the system information of the cell. However, in the 5G communication, for an indoor coverage scenario, the Access Point (AP) broadcasts the system information of the cell, so that the terminal device accesses the corresponding cell, but in the prior art, when the PLMN is the same in the system information of the cell broadcasted by the base station and the AP, the terminal device cannot distinguish the system information of the cell broadcasted by the base station and the AP, and thus the communication to the terminal device in the cell of the AP is easily affected.

Detailed Description

Generally, a base station may broadcast system information of a cell, so that a terminal device may access the corresponding cell according to the system information of the cell.

The third Generation Partnership Project (3 GPP) Release18 standard began to study home 5G, where one important scenario is indoor coverage. In the indoor coverage scene, the system information of the cell is broadcasted by the 5GAP, so that the terminal equipment accesses the corresponding cell according to the system information of the cell.

However, the coverage ranges of the cell of the 5GAP and the cell of the base station are usually different, generally, the coverage range of the cell of the base station is large and may be generally referred to as a macro cell, and the User may set a corresponding User Group (User Group) for the cell of the 5GAP, and access to the terminal device identified by the terminal device identifier in the User Group may be referred to as a Private User Group (PUG), a Closed Subscriber Group (CSG), or the like. For example, a user group is referred to as a PUG, and a cell of a 5GAP may be referred to as a PUG cell.

If too many terminal devices are accessed in the PUG cell, the communication quality of the terminal devices is easily affected. Therefore, the research on how the terminal device identifies the system information of the macro cell and the PUG cell having the same Public Land Mobile Network (PLMN) so that the terminal device can access the corresponding cell has important practical value.

The embodiment of the application provides a network access method, so that a terminal device can identify whether the system information is macro cell or not, and the terminal device can access a corresponding cell according to the system information of the corresponding cell.

First, some terms referred to in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

1. And (4) terminal equipment. The terminal device in the embodiment of the present application may be a device with a wireless transceiving function, and may also be referred to as a terminal, a User Equipment (UE), a User Terminal (UT), and the like, and may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device in the embodiment of the application can comprise a handheld device, an in-vehicle device, a wearable device or a computing device with a wireless communication function. Illustratively, the terminal device may be a mobile phone (mobile phone), a tablet computer or a computer with wireless transceiving function. The terminal device may also be a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and so on. In the embodiment of the present application, the apparatus for implementing the function of the terminal may be a terminal; it may also be a device, such as a system-on-chip, capable of supporting the terminal to implement the function, which may be installed in the terminal. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices.

In the embodiment of the present application, the terminal device may be divided into a first terminal device and a second terminal device based on a protocol version and/or a chip type, and the like. The first terminal device may be referred to as a new terminal device, for example, a terminal device after the R18 standard and the R18 standard. The second terminal device may also be referred to as a legacy terminal device, e.g., a legacy terminal device prior to the R18 standard.

2. A network device. The network device of the embodiment of the present application may be a device that is deployed in a radio access network and is capable of performing wireless communication with a terminal device. For example, the network device may be a base station, which may have various forms, such as a macro base station, a micro base station, and the like. For another example, the network device may also be a relay station or an access point, such as a 5 GAP. In the embodiment of the present application, the apparatus for implementing the function of the network device may be a network device; or may be a device, such as a system-on-chip, capable of supporting the network device to implement the function, and the device may be installed in the network device.

For example, in the embodiment of the present application, the network device may be divided into a first network device and a second network device based on a protocol version and/or a chip type, and the like. Illustratively, the cell of the first network device is a first cell, e.g., a PUG cell. The cell of the second network device is a second cell, such as a macro cell.

3. And (4) system information. The system information in the embodiment of the present application may include a Master Information Block (MIB) and a system information block 1 (SIB 1) SIB 1. Where MIB and SIB1 belong to RRC messages. In other embodiments, the system information may also include SIB2, SIB3, SIB4, SIB5, SIB6, SIB7, SIB8, SIB9, SIB10, SIB11, and the like.

In some embodiments, the message types corresponding to the system information of different types of cells are different. Take system information as MIB as an example. For example, the broadcast control channel-broadcast channel information BCCH-BCH-Message type corresponding to the MIB of the macro cell is MIB, and the BCCH-BCH-Message type corresponding to the MIB of the PUG cell is BCCH-BCH-Message type is Message class extension. Alternatively, the system information is SIB1 for example. For example, the broadcast control channel-downlink shared channel information BCCH-DL-SCH-Message type corresponding to the SIB1 of the macro cell is C1, and the BCCH-DL-SCH-Message type corresponding to the SIB1 of the PUG cell is messageClassExtension. In other embodiments, the system information for different types of cells correspond to different encryption schemes. Take system information as MIB as an example. The MIB of the macro cell is not encrypted, the MIB of the PUG cell is the MIB after conversion, and the conversion mode can be encryption or field sequence adjustment.

For another example, for the MIB of the PUG cell, the Synchronization Signal Block-subcarrier offset SSB-subcarrier offset field in the MIB is set to indicate that SIB1 does not exist, and the system information Block 1 pdcch configuration pdcch-ConfigSIB1 field in the MIB is set to a first frequency domain position having a frequency domain offset from the frequency domain position of the physical broadcast channel Block (Synchronization Signal and PBCH Block, SSB), and the first field included in the MIB is used to indicate the frequency domain offset. For the first terminal device, after receiving the MIB, if it is recognized that the SSB-subcarrieronoffset field indicates that SIB1 does not exist, the first field and the pdcch-ConfigSIB1 field in the MIB are continuously recognized, the frequency domain location of the SSB is determined according to the pdcch-ConfigSIB1 field and the first field, and the SSB is acquired, so as to access the cell. For the second terminal device, after receiving the MIB, if it is recognized that the SSB-subcarrieronoffset field indicates that the SIB1 does not exist, the first frequency domain position obtained after reading the pdcch-ConfigSIB1 field has a certain offset from the actual frequency domain position where the SSB is located, and since the second terminal device does not read the first field, the second terminal device cannot obtain the SSB, and determines that the cell is not a macro cell, and thus does not access the cell.

For another example, for the MIB of the PUG cell, the cell barred field in the MIB is set to be barred, but the intra freq selection field in the frequency domain in the MIB is set to be allowed. For the first terminal device, after receiving the MIB, if it is recognized that the cellBarred field is set to barred, the intrafreq reselection field continues to be recognized. If the intraFreqReselection field is set to allowed, the MIB is determined to be the MIB of the PUG cell, and the cell is accessed. For the second terminal device, after receiving the MIB, if it is recognized that the cellBarred field is set to barred, it may be determined that the MIB is not the MIB of the macro cell, and the intrafreq reselection field is no longer recognized, so that the cell is not accessed.

For another example, for the SIB1 of the PUB cell, the cellreservefforuse field and/or cellReservedForUse field in the SIB1 is set to true. For the first terminal device, the SIB1 is received. If the first terminal device identifies that the cellReservefForUse field or the cellReservedForUse field is set to true, the SIB1 is determined to be the SIB1 of the PUB cell, and the cell is accessed. And for the second terminal device, the SIB1 is received. And the second terminal equipment identifies that the cellReservedForUse field and/or the cellReservedForUse field is set to true, and judges not to access the cell.

Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Plural in the embodiments of the present application refers to two or more.

In the embodiment of the application, "/" indicates that A and/or B can comprise A, B, A and B.

The embodiment of the application can be applied to but not limited to: a narrowband band-internet of things (NB-IoT), an Enhanced Machine Type Communication (eMTC) system, a Long Term Evolution (LTE) Cat1 system, a fifth generation mobile Communication (5th-generation, 5G) system, and a future mobile Communication system. As an example, as shown in fig. 1, a network architecture diagram of a communication system according to an embodiment of the present application includes a network device, a first terminal device, and a second terminal device. Fig. 1 is an illustration only, and does not limit the embodiments of the present application. For example, in the embodiment of the present application, the network architecture of the communication system is not limited to include one or more network devices or one or more terminal devices.

A method for network access according to an embodiment of the present application is described with reference to a network architecture shown in fig. 1 as an example.

Illustratively, as shown in fig. 2, a network access method provided in the embodiment of the present application specifically includes the following steps.

201. The network equipment sends indication information, wherein the indication information indicates a first cell, and the first cell is not a macro cell.

Illustratively, the network device obtains the indication information and transmits the indication information. For example, the network device broadcasts indication information. The indication information may be carried in an RRC message, or system information (e.g., MIB, or SIB1), etc., which is not limited herein.

In a possible implementation manner, the indication information is used to indicate a broadcast control channel-broadcast channel Message BCCH-BCH-Message type, where the broadcast control channel-broadcast channel Message includes necessary information required by the terminal device to perform network selection, and the indication information indicates that the type of the broadcast control channel-broadcast channel Message is a Message class extension type, and since the second terminal device cannot resolve the information that the type of the information is the Message class extension type, it cannot acquire valid information, that is, the cell is considered to be a cell that is not supported by itself or an abnormal cell, thereby avoiding accessing the cell. The first terminal device can analyze the information of the message type extension type, so that the effective information can be acquired, and the cell network can be determined to be accessible. Therefore, it is advantageous to avoid conventional terminal devices prior to the R18 standard from camping on private user group cells in this manner.

The message format of the broadcast control channel-broadcast channel message is defined as follows:

further, in some embodiments, the indication information indicates that the type of the broadcast control channel-broadcast channel message is a message category extension type, and a format and content of a Master Information Block (MIB) that actually transmits the message category extension type may still be the same as an existing MIB, or a format and content of a new MIB may be redefined, which is not limited in this embodiment of the present application.

Or, in another possible implementation manner, the indication information is used to indicate a broadcast control channel-downlink shared channel Message BCCH-DL-SCH-Message type, where the broadcast control channel-downlink shared channel Message includes necessary information required by the terminal device to perform network selection. The indication information indicates that the type of the broadcast control channel-downlink shared channel message is a message class extension type messageclassExtension, and since the second terminal device cannot analyze the message type as the message class extension type, effective information cannot be acquired, that is, the cell is considered to be a cell which is not supported by the second terminal device or an abnormal cell, thereby avoiding accessing the cell. The first terminal device can analyze the information of the message type extension type, so that the effective information can be acquired, and the cell network can be determined to be accessible. In this way it may be advantageous to avoid legacy terminal devices that were formerly the R18 standard to camp on private user group cells.

The message format of the broadcast control channel-downlink shared channel message is defined as follows:

optionally, the network device may select the type of the system information block 1 (SIB 1) as the message class extension type, and still select the type of the system information block (SI) as the c1 type, because the terminal device only needs to read the SIB1 during cell selection or cell reselection. The SIB1 of the message class extension type may still reuse the format and content of the existing SIB1 or may redefine the format and content of the new SIB 1.

Optionally, the network device may select both the type of SIB1 and the type of SI as messageclasssextension. At this time, the actually extended source needs to add a selected CHOICE of the choiceformat, similar to the type c1, and further indicate whether the determined SIB1 or SI is used, and at this time, the message format of the broadcast control channel-downlink shared channel message may be redefined as follows:

the SIB1 or SI of the messageClassExtension type may still reuse the format and content of the existing SIB1 or SI, or may redefine the format and content of the new SIB1 or SI.

In another possible implementation, the indication information is transformed system information. The transformed system information may be encrypted system information, or may be system information with part of the field sequence adjusted, which is not limited in this embodiment of the present application. The system information may be MIB or SIB 1. The second terminal device cannot read the MIB or SIB1 since the system information is transformed. However, the MIB or SIB1 contains the necessary information to access the cell network, so that the second terminal device cannot access the cell network. The first terminal device can analyze the transformed system information, so that the information in the system information can be acquired to determine that the cell network can be accessed. In this way it is advantageously avoided that the terminal device formerly according to the R18 standard resides in the private subscriber group cell.

In another possible implementation, the indication information includes a Synchronization Signal Block-subcarrier offset SSB-subcarrier offset field, a system information Block 1 pdcch configuration pdcch-ConfigSIB1 field, and a first field, the Synchronization Signal Block-subcarrier offset field indicating that the system information Block 1 is not present, the system information Block 1 pdcch configuration field indicating a first frequency domain location, and the first field indicating an offset value of a frequency domain location of a primary secondary Synchronization Signal and a physical broadcast channel Block (Synchronization Signal and PBCH Block, SSB) of the cell with respect to the first frequency domain location. Since the second terminal device understands that the synchronization signal block-subcarrier offset field indicates that the system information block 1 does not exist based on the existing protocol, the second terminal device will read the physical downlink control channel-system information block 1 to obtain the first frequency domain position. However, since the first frequency domain position indicated by the physical downlink control channel-system information block 1 and the actual frequency domain position of the SSB have an offset value, the second terminal device cannot acquire the actual frequency domain position where the primary and secondary synchronization signals and the physical broadcast channel block of the cell are located, and therefore cannot access the network of the cell. Since the first terminal device reads the content of the first field, determines the frequency domain position of the actual SSB according to the first field and the pdcch-system information block 1, and acquires the SSB, the first terminal device can access the cell network. In this way it is advantageously avoided that the terminal device formerly according to the R18 standard resides in the private subscriber group cell.

In another possible implementation manner, the indication information is preset access control configuration (UAC) information. The access control configuration information is an Access Identity (AI) or an access policy (AC). The user identifier of the second terminal device is forbidden to be accessed by the access identifier or the access policy, so that the second terminal device does not select to access the cell network after the second terminal device reads the indication information and determines that the user identifier of the second terminal device is forbidden to be accessed by the cell network. Since the subscriber identity of the first terminal device is not barred, the first terminal device may access the cell network. In this way it is advantageously avoided that the terminal device formerly according to the R18 standard resides in the private subscriber group cell.

In another possible implementation manner, the indication information includes a forbidden cell cellBarred field set as forbidden and an intra-frequency reselection intraFreqReselection field set as allowed. The second terminal device reads the indication information to determine that the cellBarred field is set as forbidden, that is, the cell is determined to be a cell which is forbidden to access, so that the second terminal device does not select to access the cell network. Since the first terminal device determines that the intrafreq reselection field is allowed after determining that the cellBarred field is prohibited, the first terminal device considers that the cell is a normal cell and can attempt to access the cell network. In this way it is advantageously avoided that the terminal device formerly according to the R18 standard resides in the private subscriber group cell.

In another possible implementation, the indication information includes information that the cell is reserved for other uses or information that the cell is reserved for future uses, and the field of the cell reserved for other uses or the field of the cell reserved for future uses is set to true. Since the field set true for cellreserveffordotheruse indicates whether the cell is reserved for other use, and the field set true for cellreserveforfutureuse indicates that the cell is reserved for future use, the second terminal device determines that the cell network is reserved for other use or for future use based on the indication information, and does not select to access the cell network. Since the first terminal device is set to consider the cell as a private user cell when determining that the cellReservedForOtherUse field or the cellReservedForFutureUse field is set to true, the first terminal device considers the cell as a normal cell and can attempt to access the cell network. In this way, it is advantageous to avoid conventional terminal equipment of the R18 standard from camping on a private user group cell.

202. And the first terminal equipment performs cell access based on the indication information access.

For example, if the first terminal device supports parsing of the indication information, the first cell is accessed, and thus the corresponding network is accessed. And if the second terminal equipment which does not support the analysis of the indication information receives the indication information, the cell access is not carried out.

In one possible implementation, the indication information is broadcast control channel-broadcast channel message type indication information, and the indication information indicates that the type of the broadcast control channel-broadcast channel message is a message class extension type. The first terminal device may analyze the information of the message category extension type, so that the first terminal device may obtain information required for network selection included in the broadcast control channel-broadcast channel message according to the read message category extension information, and the first terminal device may access the cell network based on the indication information. And the second terminal equipment cannot access the cell network because the second terminal equipment cannot analyze the information of the message type extension type.

In another implementation manner, the broadcast control channel-downlink shared channel Message BCCH-DL-SCH-Message type indication information is broadcast control channel-downlink shared channel Message type indication information, and the indication information indicates that the type of the broadcast control channel-downlink shared channel Message is a Message type extension type. The first terminal device may analyze the information of the message type extension type, so that the first terminal device obtains information required for network selection included in the broadcast control channel-broadcast channel message according to the read message type extension information, and therefore the first terminal device may access the cell network based on the indication information, and the second terminal device may not access the cell network because the second terminal device may not analyze the information of the message type extension type.

In another implementation, the indication information is transformed system information. The converted system information may be encrypted system information or may be a field in which the order of the relevant fields is adjusted. The system information may be MIB or SIB 1. After receiving the MIB, if the first terminal device determines that the MIB is changed, analyzing the MIB, and if the MIB can be successfully analyzed, also reading the SIB1 successfully, then the first terminal device accesses the cell network based on the system information; if the MIB is not transformed and the SIB1 is determined to be transformed after reading the MIB, the SIB1 is analyzed, and if the SIB1 is successfully analyzed, the first terminal device accesses the cell network based on the system information. The second terminal device cannot read the MIB or SIB1, so the second terminal device cannot access the cell network.

For example, the system information of the PUG cell is encrypted by the first algorithm, and the system information of the macro cell is not encrypted. The first algorithm may be defined by a protocol, or may be predetermined by the network device and the first terminal device, and the like, which is not limited herein. For example, the first algorithm may be an Advanced Encryption Standard (AES), a ZUC algorithm (grand-bust algorithm), or a snow algorithm (snowflake algorithm).

Or, for the system information of the PUG cell, the format of the system information is a first format, and for the system information of the macro cell, the format of the system information is a second format, where the second format may be the format of an existing system message, the position order of each field of the system information does not change, and the position order of each field of the system information of the first format may be different from the position order of each field of the system information of the second format, and/or the field parts are different, and so on.

In another possible implementation manner, the indication information includes a synchronization signal block-subcarrier offset field, a system information block 1 physical downlink control channel configuration field, and a first field, where the synchronization signal block-subcarrier offset field indicates that the system information block 1 does not exist, the system information block 1 physical downlink control channel configuration field indicates a first frequency domain position, and the first field is used to indicate an offset value of a frequency domain position where a primary and secondary synchronization signal and a physical broadcast channel block of a cell are located relative to the first frequency domain position. The first terminal device may determine the frequency domain location of the SSB of the cell according to the system information block 1 physical downlink control channel configuration field and the first field, and thus the first terminal device may access the cell network based on the indication information. Since the second terminal device cannot acquire the true frequency domain position of the SSB of the cell only by reading the physical downlink control channel-system information block 1, the second terminal device cannot access the network of the cell.

In another possible implementation manner, the indication information is preset access control configuration information. The preset access control configuration information is a finger access identifier or an access strategy. The second terminal device is prohibited from accessing the cell network because the user identifier of the second terminal device is prohibited from accessing in the access identifier or access policy setting. The first terminal device is not barred, so the first terminal device can access the cell network based on the indication information.

In another possible implementation manner, the indication information includes a cell barred field set as forbidden and an intra-frequency reselection intrafreq selection field set as allowed. The first terminal device reads the indication information to determine that the cellBarred field is set as forbidden, then reads the intrafreq reselection field as allowed, which indicates that the reselection in the frequency domain can be performed in the frequency domain selection or reselection.

In another possible implementation, the indication information includes information that the cell is reserved for other uses or information that the cell is reserved for future uses, and the field of the cell reserved for other uses or information that the cell reserved for future uses is set to true. Since the cellreserveffordotheruse field set true indicates whether the cell is reserved for other use, the cellreserveforfutureuse field set true indicates that the cell is reserved for future use. However, when the first terminal device reads the cellReservedForOtheruse field or the cellReservedForFutureuse field to be set to true, the cell is considered to be a private user group cell, and therefore the first terminal device selects to access the cell network.
