Detailed Description
In general, the base station may broadcast system information of a cell, so that the terminal device may access the corresponding cell according to the system information of the cell.
The third generation partnership project (The 3rd Generation Partnership Project,3GPP) Release18 standard began to study home 5G, with one important scenario being indoor coverage. In the indoor coverage scene, the system information of the cell is broadcasted by the 5GAP, so that the terminal equipment is accessed into the corresponding cell according to the system information of the cell.
However, the coverage of the 5GAP cell and the coverage of the base station cell are generally different, in general, the coverage of the base station cell is larger and may be generally referred to as a macro cell, and the user may set a corresponding user group (usersroup) for the 5GAP cell, and the user group may be referred to as a private user group (Private User Group, PUG), a closed user group (Closed Subscriber Group, CSG), or the like for the terminal equipment access identified by the terminal equipment identifier in the user group. Taking the user group as PUG as an example, a 5GAP cell may be referred to as a PUG cell.
If the number of terminal devices accessed in the PUG cell is too large, the communication quality of the terminal devices is easily affected. Therefore, the research on how the terminal equipment identifies the system information of the macro cell and the PUG cell of the same public land mobile network (Public Land Mobile Network, PLMN) is performed, so that the terminal equipment accesses the corresponding cell, and the method has important practical value.
The embodiment of the application provides a network access method, which enables terminal equipment to identify whether the system information is the system information of a macro cell, so that the terminal equipment can access the corresponding cell according to the system information of the corresponding cell.
First, some terms related to embodiments of the present application are explained for easy understanding by those skilled in the art.
1. And a terminal device. The terminal device in the embodiment of the present application may be a device with a wireless transceiver function, and may also be referred to as a terminal, a User Equipment (UE), a User Terminal (UT), etc., which may be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal device in the embodiment of the application may include a handheld device, an in-vehicle device, a wearable device or a computing device with a wireless communication function. The terminal device may be a mobile phone, a tablet computer, or a computer with a wireless transceiver function, for example. The terminal device may also be a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc. In the embodiment of the present application, the device for implementing the function of the terminal may be the terminal; or may be a device, such as a chip system, capable of supporting the terminal to perform the function, which may be installed in the terminal. In the embodiment of the application, the chip system may be formed by 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, etc. The first terminal device may be referred to as a new terminal device, for example, a terminal device in the R18 standard or after the R18 standard. The second terminal device may also be referred to as a legacy terminal device, e.g. a legacy terminal device before the R18 standard.
2. A network device. The network device in the embodiment of the application may be a device deployed in a radio access network and capable of performing wireless communication with a terminal device. For example, the network device may be a base station, which may take many forms, such as a macro base station, a micro base station, etc. As another example, the network device may also be a relay station or an access point, such as a 5GAP or the like. In the embodiment of the present application, the means for implementing the function of the network device may be the network device; or may be a device, such as a system-on-a-chip, capable of supporting the network device to perform this function, which 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, etc. The cell of the first network device is, for example, a first cell, e.g. a PUG cell. The cell of the second network device is a second cell, such as a macrocell.
3. System information. The system information in embodiments of the present application may include a master information block (maste information block, MIB) and a system information block 1 (system information block, sib1) SIB1. Wherein MIB and SIB1 belong to RRC message. 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 the different types of cells are different. Taking system information as MIB for example. For example, the broadcast control channel-broadcast channel information BCCH-BCH-Message type corresponding to the MIB of the macro cell is the MIB, and the BCCH-BCH-Message type corresponding to the MIB of the PUG cell is the BCCH-BCH-Message type is the Message class extension. Alternatively, system information is taken as SIB1 as an example. For example, the broadcast control channel-downlink shared channel information BCCH-DL-SCH-Message type corresponding to SIB1 of the macro cell is C1, and the BCCH-DL-SCH-Message type corresponding to SIB1 of the PUG cell is Message ClassExtension. In other embodiments, the system information of the different types of cells corresponds to different encryption modes. Taking system information as MIB for example. The MIB of the macro cell is not encrypted, and the MIB of the PUG cell is the MIB after transformation, and the transformation mode can be encryption or field sequence adjustment.
For another example, for MIB of PUG cell, a synchronization signal block-subcarrier offset SSB-subcarrier offset field in MIB is set to indicate SIB1 is not present, a system information block 1 physical downlink control channel configuration pdcch-ConfigSIB1 field in MIB is set to a first frequency domain location having a frequency domain offset from a frequency domain location of a physical broadcast channel block (Synchronization Signal and PBCH Block, SSB), and the first field included in MIB is used to indicate the frequency domain offset. For the first terminal device, after receiving the MIB, if it is identified that the SSB-subsearrieroffset field indicates that SIB1 does not exist, the first terminal device continues to identify the pdcch-ConfigSIB1 field and the first field in the MIB, and determines a frequency domain position of the SSB according to the pdcch-ConfigSIB1 field and the first field, so as to obtain the SSB, thereby accessing the cell. And for the second terminal device, after receiving the MIB, if it is identified that the SSB-subsuccrieroffset field indicates that SIB1 does not exist, the first frequency domain position obtained after reading the pdfch-ConfigSIB 1 field has a certain offset from the frequency domain position where the actual SSB is located, and since the second terminal device does not read the first field, the second terminal device cannot obtain the SSB, and recognizes that the cell is not a macrocell, so that the cell is not accessed.
For another example, for the MIB of PUG cell, the forbidden cell barred field in MIB is set to forbidden, but reselection in the frequency domain in MIB is set to allowed. For the first terminal device, after receiving the MIB, if it is identified that the cellBarred field is set to barred, the intra freqreselection field may be continuously identified. If the INTRAFreqReselection field is set to allowed, the MIB is determined to be the MIB of the PUG cell, thereby accessing the cell. For the second terminal device, after receiving the MIB, if the cellBarred field is identified to be barred, it is determined that the MIB is not the MIB of the macrocell, and the intraFreqReselection field is not continuously identified, so that the cell is not accessed.
For another example, for SIB1 of the PUB cell, the cellReserveForUse field and/or the cellReservedForUse field in SIB1 is set to true. For the first terminal device, SIB1 is received. And if the first terminal equipment recognizes that the celReserveForuse field or the celReservedForuse field is set to true, judging that the SIB1 is the SIB1 of the PUB cell, and accessing the cell. Whereas for the second terminal device SIB1 is received. The second terminal equipment recognizes that the cellReserve Foruse field and/or the cellReserve Foruse field is set to true, and judges that the cell is not accessed.

Embodiments of the present application may be applied to, but are not limited to: narrowband internet of things (NB-IoT), enhanced machine type communication (Enhanced Machine Type of Communication, eMTC), long term evolution (long term evolution, LTE), long term evolution (Long Term Evolution, LTE) Cat1, fifth generation mobile communication (5 th-generation, 5G) and future mobile communication systems. As shown in fig. 1, an exemplary 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 merely an illustration and is not intended to limit embodiments of the present application. For example, in the embodiment of the present application, one or more network devices, or one or more terminal devices may be included in a network architecture of a communication system without limitation.
Taking the network architecture shown in fig. 1 as an example, a method for accessing a network in an embodiment of the present application is described.
As shown in fig. 2, an example, a network access method provided in an embodiment of the present application specifically includes the following steps.
201. The network device sends indication information indicating the first cell, and the first cell is not a macrocell.
For example, the network device obtains the indication information and sends the indication information. For example, the network device broadcasts the indication information. The indication information may be carried in an RRC message, or system information (for example, MIB, SIB 1) or the like, which is not limited.
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 information necessary for the terminal device to perform network selection, the indication information indicates that the type of the broadcast control channel-broadcast channel Message is a Message type extension type Message extension type, and since the second terminal device cannot parse the information that the information type is the Message type extension type, valid information cannot be obtained, that is, the cell is considered to be a cell that is not supported by itself or is an abnormal cell, so as to avoid accessing the cell. Since the first terminal device can analyze the information of the message type extension type, effective information can be obtained, and the cell network can be determined to be accessed. In this way, it is therefore advantageously possible to avoid that legacy terminal equipment before the R18 standard resides in private subscriber group cells.
Wherein, 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 type extension type, and the format and content of a master information block (master information block, MIB) actually transmitting the message type extension type may still be the same as the existing MIB, or the format and content of a new MIB may be redefined, which is not limited in the embodiments of the present application.
Alternatively, 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 information necessary for the terminal device to perform network selection. The indication information indicates that the type of the broadcast control channel-downlink shared channel message is message type extension type message class extension, and because the second terminal equipment cannot analyze the information of which the information type is the message type extension type, effective information cannot be obtained, namely the cell is considered to be an unsupported cell or an abnormal cell, so that the cell is prevented from being accessed. Since the first terminal device can analyze the information of the message type extension type, effective information can be obtained, and the cell network can be determined to be accessed. In this way it can be advantageous to avoid that legacy terminal devices before the R18 standard reside in private subscriber group cells.
Wherein, the message format of the broadcast control channel-downlink shared channel message is defined as follows:
alternatively, the network device may select the type of system information block 1 (system information block 1, sib1) as the message class extension type, and the type of system information (system information, SI) is still selected as the c1 type, since the terminal device only needs to read SIB1 when selecting or reselecting a cell. SIB1 of the message category extension type may still multiplex the format and content of the existing SIB1, or may redefine the format and content of the new SIB1.
Alternatively, the network device may select both the type of SIB1 and the type of SI as the message classextension. At this time, the actually extended source also needs to add a CHOICE of choicef format similar to the c1 type, further indicating whether SIB1 or SI is determined, 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 message class extension type may still multiplex 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 a part of field sequences adjusted, which is not limited in the embodiment of the present application. The system information may be MIB or SIB1. The second terminal device cannot read the MIB or SIB1 since the system information is transformed. However, MIB or SIB1 contains information necessary for accessing the cell network, so the second terminal device cannot access the cell network. The first terminal equipment can analyze the transformed system information, so that the information in the system information can be acquired, and the cell network can be determined to be accessed. In this way it is advantageously avoided that terminal equipment before the R18 standard resides in the private subscriber group cell.
In another possible implementation manner, the indication information includes a synchronization signal block-subcarrier offset SSB-subcarrier offset field, a system information block 1 physical downlink control channel configuration pdcch-ConfigSIB1 field, and a first field, where the synchronization signal block-subcarrier offset field indicates that the system information block 1 does not exist, and the system information block 1 physical downlink control channel configuration field indicates a first frequency domain location, where the first field is used to indicate an offset value of a frequency domain location where a primary and secondary synchronization signal and a physical broadcast channel block (Synchronization Signal and PBCH Block, SSB) of a cell are located relative to the first frequency domain location. Since the second terminal device understands based on the existing protocol that the synchronization signal block-subcarrier offset field indicates that the system information block 1 is not present, the second terminal device will read the physical downlink control channel-system information block 1 to obtain the first frequency domain location. However, since the first frequency domain position indicated by the physical downlink control channel-system information block 1 has an offset value from the frequency domain position where the actual SSB is located, the second terminal device cannot acquire the primary and secondary synchronization signals of the cell and the actual frequency domain position where the physical broadcast channel block is located, so that the network of the cell cannot be accessed. The first terminal equipment can access the cell network because the first terminal equipment can read the content of the first field, determine the frequency domain position of the actual SSB according to the first field and the physical downlink control channel-system information block 1, and acquire the SSB. In this way it is advantageously avoided that terminal equipment before the R18 standard resides in the private subscriber group cell.
In another possible implementation, the indication information is preset access control configuration (unified access control, UAC) information. The access control configuration information is either an access identity (AccessIdentity, AI) or an access policy (AccessCategory, AC). By setting the access prohibition of the user identification of the second terminal device in the access identification or the access policy, after the second terminal device reads the indication information, it is determined that the user identification of the second terminal device is prohibited from being accessed by the cell network, so that the second terminal device does not select to access the cell network. The first terminal device may access the cell network since the user identity of the first terminal device is not barred. In this way it is advantageously avoided that terminal equipment before the R18 standard resides in the private subscriber group cell.
In another possible implementation, the indication information includes a forbidden cell barred field, which is set to forbidden, and a frequency domain reselection intra freqreselection field, which is set to allowed. Since the second terminal device reads the indication information to determine that the cellBarred field is set to inhibit, i.e. determines that the cell is an access-inhibited cell, the second terminal device does not select to access the cell network. Since the first terminal device determines that the interfreqreselection field is set to enable after determining that the cellBarred field is set to disable, the first terminal device considers the cell as a normal cell and can attempt to access the cell network. In this way it is advantageously avoided that terminal equipment before the R18 standard resides in the private subscriber group cell.
In another possible implementation, the indication information includes cell reservation for other use of the celReserve ForFutureuse field information or cell reservation for future use of the celReserve ForFutureuse field information, where the celReserve ForOtheruse field or celReserve ForFutureuse field is set to true. Since the cellReserve Forother field setting true indicates whether the cell is reserved for other use, and the cellReserve Forfutureuse field setting true indicates that the cell is reserved for future use, the second terminal device determines that the cell network is reserved for other use or reserved for future use based on the indication information, and does not select to access the cell network. Since the first terminal equipment is set to consider the cell as a private user cell when determining that the cellReserve ForOtheruse field or the cellReserve ForFutureuse field is set to true, the first terminal equipment considers the cell as a normal cell and can attempt to access the cell network. In this way, it is advantageous to avoid that conventional terminal devices of the R18 standard reside in private subscriber group cells.
202. And the first terminal equipment performs cell access based on the indication information access.
For example, the first terminal device supports parsing the indication information, and accesses the first cell, thereby accessing the corresponding network. 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 performed.
In one possible implementation, the indication information is broadcast control channel-broadcast channel message type indication information, which indicates that the type of broadcast control channel-broadcast channel message is a message type extension type. The first terminal device can analyze the information of the message type expansion type, so that the first terminal device can acquire the information required by network selection contained in the broadcast control channel-broadcast channel message according to the read message type expansion information, and the first terminal device can access the cell network based on the indication information. And the second terminal equipment cannot analyze the information of the message type extension type, so that the second terminal equipment cannot access the cell network.
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 can analyze the information of the message type extension type, so the first terminal device obtains the information required by the network selection contained in the broadcast control channel-broadcast channel message according to the read information of the message type extension type, the first terminal device can access the cell network based on the indication information, and the second terminal device cannot access the cell network because the information of the message type extension type cannot be analyzed.
In another implementation, the indication information is transformed system information. The transformed system information may be encrypted system information or may be a field in which the order of related fields is adjusted. The system information may be MIB or SIB1. After the first terminal equipment receives the MIB, if the MIB is determined to be transformed, the MIB is analyzed, if the MIB can be successfully analyzed, the SIB1 can also be successfully read, and the first terminal equipment is accessed to a cell network based on the system information; if the MIB is not transformed, and after the MIB is read, the SIB1 is determined to be transformed, the SIB1 is analyzed, and if the SIB1 is successfully analyzed, the first terminal equipment accesses the cell network based on the system information. And 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 agreed by the network device and the first terminal device in advance, which is not limited. The first algorithm may be, for example, an advanced encryption standard algorithm (Advanced Encryption Standard, AES), a ZUC algorithm (ancestral algorithm), or a snowflake algorithm.
Alternatively, for the system information of the PUG cell, the format of the system information is a first format, for the system information of the macro cell, the format of the system information is a second format, wherein the second format may be a format of an existing system message, the position order of each field of the system information is not changed, and 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 part is different, etc.
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 location, and the first field is used to indicate an offset value of a frequency domain location where a primary synchronization signal and a physical broadcast channel block of a cell are located relative to the first frequency domain location. 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, so the first terminal device may access the cell network based on the indication information. The second terminal equipment can not access the network of the cell because the second terminal equipment only reads the physical downlink control channel-system information block 1 and can not acquire the real frequency domain position of the SSB of the cell.
In another possible implementation, the indication information is preset access control configuration information. The preset access control configuration information refers to an access identifier or an access policy. The second terminal device is prohibited from accessing the cell network because the user identification of the second terminal device is prohibited from accessing by setting an access identification or an access policy. And the first terminal device is not disabled, the first terminal device may access the cell network based on the indication information.
In another possible implementation, the indication information includes a forbidden cell field, which is set to forbidden, and an intra freqreselection field in the frequency domain, which is set to allowed. After the first terminal device reads the indication information to determine that the cellBarred field is set to be forbidden, the first terminal device reads the intraFreqReselection field to be allowed, which means that the intra-frequency domain reselection can be performed for intra-frequency domain selection or reselection, the first terminal device accesses the cell network based on the indication information, and the second terminal device only reads the indication information to determine that the forbidden cell field is set to be forbidden, so that the second terminal device does not access the cell network.
In another possible implementation, the indication information includes cell reservation for other use of the celReserve ForFutureuse field information or cell reservation for future use of the celReserve ForFutureuse field information, where the celReserve ForOtheruse field or celReserve ForFutureuse field is set to true. Since the cellReserve ForOtheruse field set true indicates whether the cell is reserved for other uses, the cellReserve ForFutureuse field set true indicates that the cell is reserved for future use. However, when the first terminal device reads the cellReserve ForOtheruse field or the cellReserve ForFutureuse field is set to true, the cell is considered to be a private user group cell, so that the cell network can be selected to be accessed.
Based on the same conception, the embodiment of the present application also provides a communication device, as shown in fig. 3, which may be used to perform part or all of the functions of the network device in fig. 2. The communication device may be a network device, a device in a network device, or a device that can be used in a matching manner with a network device. The communication device may also be a chip system. The communication device shown in fig. 3 may include acommunication unit 301 and aprocessing unit 302. Theprocessing unit 302 is configured to perform data processing. Acommunication unit 301 for communicating with other devices. Thecommunication unit 301 integrates a receiving unit and a transmitting unit. Thecommunication unit 301 may also be referred to as a transceiving unit. Alternatively, thecommunication unit 301 may be split into a receiving unit and a transmitting unit. Theprocessing unit 302 and thecommunication unit 301 are the same as each other, and will not be described in detail. Wherein:
