Technical field

The present application relates to the field of communications technologies, and in particular, to an access method and related devices.

Background technique

In the prior art, the process of the terminal accessing the cell is: after the terminal is powered on, the terminal needs to perform cell search on the frequency corresponding to the terminal type. After searching for the cell, the terminal determines whether the terminal can be connected according to the signal strength or signal quality of the cell. Entering the cell, if possible, the terminal accesses the cell.

The frequency corresponding to the terminal type is bound to the type of the radio access technology (RAT). As the wireless communication technology evolves, the same frequency is assigned to different RAT types, for example, The type of the RAT of the 4th generation mobile communication (4G) and the type of the RAT of the fifth generation mobile communication technology (5th-generation, 5G) are assigned the same frequency, and one cell can simultaneously support the 4G RAT type. And the 5G RAT type, in the case that the frequency allocated for the terminal is simultaneously bound to the type of the 4G RAT and the type of the 5G RAT, a 4G or 5G terminal can perform cell search on the allocated frequency. Cell selection access and cell reselection access operations.

However, if the frequency allocated for the partial cell is only bound to the RAT type of 5G, and the frequency allocated for one 4G terminal is simultaneously bound to the type of the 4G RAT and the type of the 5G RAT, the 4G If the terminal is connected to the cell that is bound to the RAT of the 5G, the terminal of the 4G cannot initiate normal services, which seriously reduces the efficiency of successfully starting the service.

Summary of the invention

The present application provides an access method and related equipment that can improve the efficiency of a terminal accessing a cell.

A first aspect of the embodiments of the present invention provides an access method, where the method includes:

Step A1: The access network device generates indication information.

The indication information is used to indicate the type of the radio access technology RAT supported by the first cell, and/or the indication information is further used to indicate the type of the RAT of the second neighboring cell of the first cell. The first cell is a cell of the access network device.

In the case that the indication information is used to indicate the type of the radio access technology RAT supported by the first cell, the indication information may be used to indicate the type of the at least one RAT supported by the first cell, and Where the indication information is used to indicate the type of the radio access technology RAT supported by the second cell, the indication information may be used to indicate the type of the at least one RAT supported by the second cell.

Step A2: The access network device sends the indication information to the terminal.

In the case that the access network device sends indication information indicating the RAT type supported by the first cell and/or the second cell to the terminal, the terminal may access the device according to the indication information. Said first cell or said second cell.

As the wireless communication technology evolves, the same cell can support multiple types of RATs, so that the same cell can support multiple versions of terminal access to successfully initiate services, but when the terminal attempts to access the cell support If the type of the RAT is inconsistent with the type of the RAT supported by the terminal, the terminal may not be able to successfully initiate the service, and the method shown in this embodiment enables the terminal to obtain the first cell and And the cell access is performed in the case of the type of the RAT supported by the second cell, to ensure that the type of the RAT supported by the cell accessed by the terminal is the same as the type of the RAT supported by the terminal. The situation that the type of the RAT supported by the terminal does not match the type of the RAT supported by the cell that the terminal accesses is avoided, thereby effectively improving the efficiency of successfully starting the service by the terminal.

Based on the first aspect of the embodiments of the present invention, in an optional implementation manner of the embodiment of the present invention,

The indication information includes a first identifier list, where the first identifier list includes at least one first identifier, where the first identifier is used to identify a RAT supported by the first cell and/or the second cell. type.

The first identifier may identify, by using a character, a type of the RAT supported by the first cell and/or the second cell. Wherein, the character may be any combination of letters, numbers, words and/or symbols used in the computer, as long as different first identifiers are different from those supported by the first cell and/or the second cell. The type corresponds to it.

It can be seen that, in the implementation manner, the access network device can identify, by using the first identifier, a type of the RAT supported by the first cell and/or the second cell, so that the terminal receives the In the case of the indication information, the type of the RAT supported by the first cell and/or the second cell may be determined according to the first identifier included in the indication information, so that the terminal can be based on the The type of the RAT supported by the first cell and/or the second cell is used for accessing the cell, so that the RAT type supported by the cell accessed by the terminal matches the RAT supported by the terminal, and the RAT is improved.

The target core network node pool may include at least one core network node, through which the target core network node pool may enable the terminal to serve the core network of the terminal when roaming in the target core network node pool The node is always located in the target core network node pool, and when the target core network node pool provides the terminal with the roaming service, the signaling interaction between the core network nodes caused by the core network node change may be reduced. The first identifier shown is also used to identify the target core network node pool, so that the terminal determines the target core network node pool serving the terminal.

Optionally, if the first cell and/or the second cell are connected to multiple core network nodes, if multiple core network nodes connected to the first cell and/or the second cell belong to the same In the target core network node pool, multiple core network nodes may correspond to the same first identifier.

Optionally, if the multiple core network nodes connected to the first cell and/or the second cell belong to different core network node pools, the first cell and/or the second cell are connected differently. The node pool corresponds to different first identifiers.

It can be seen that, by using the implementation, the access network device can identify the target core network node pool to the terminal by using the first identifier included in the indication information, so that the terminal is in the target core network node pool. When roaming, the signaling interaction between the core network nodes that provide roaming services for the terminal is effectively reduced, thereby saving overhead.

The indication information includes a second identifier list, where the second identifier list includes at least one second identifier, the second identifier is used to correspond to a target PLMN, and the target PLMN is the first cell and/or Or a PLMN supported by the second cell.

The access network device may pre-create a corresponding relationship between the PLMN and the identifier, where the access network device may acquire the core network node to which the access network device is connected, in the process of generating the indication information, And obtaining a target PLMN corresponding to the core network node connected to the access network device, and determining, according to a predetermined correspondence between the different PLMN and the identifier, the second identifier corresponding to the target PLMN. The second identifier may identify a PLMN supported by the first cell and/or the second cell by using a character.

It can be seen that, in the implementation manner, the access network device identifies, by using the second identifier, a target PLMN corresponding to the core network node to which the access network device is connected, so that the terminal determines, according to the target PLMN, The PLMN supported by the first cell and/or the second cell, so that the terminal can be consistent according to the PLMN supported by the cell accessed by the second identifier and the PLMN supported by the terminal itself, thereby avoiding the terminal If the PLMN supported by the accessed cell is inconsistent with the PLMN supported by the terminal itself, the terminal cannot initiate the service. It can be seen that the implementation manner can effectively improve the efficiency of successfully starting the service.

The third identifier is an identifier when the first cell and/or the second cell accesses the type of the RAT.

The indication information further includes a third identifier, where the third identifier is a cell identifier when the first cell and/or the second cell accesses a type of the supported RAT.

If the indication information is used to indicate that the type of the RAT that the first cell and/or the second cell accesses is one, the third identifier is when the cell accesses the type of the RAT. Cell identity.

If the indication information is used to indicate that the type of the RAT that is accessed by the first cell and/or the second cell is multiple, the indication information may include multiple third identifiers, and different The third identifier is used to identify the type of different RATs that the first cell and/or the second cell access.

The indication information includes a first cell, where the first cell is used to indicate that the state of the first cell is a forbidden access state for a type of the first RAT, and the type of the first RAT is the terminal The type of RAT supported.

The privilege of the cell, that is, the state in which the first cell is forbidden to access, the terminal does not reside in the first cell, thereby avoiding a terminal that does not support the type of the first RAT. The signaling overhead caused by camping in the first cell.

The indication information includes a second cell, where the second cell is used to indicate that the state of the first cell is an allowed access state for a type of the second RAT, and the type of the second RAT is the terminal The type of RAT supported.

It can be seen that, in this implementation manner, if the RAT type supported by the terminal is consistent with the RAT type supported by the first cell, the indication information shown in this implementation manner further includes a second cell, where the terminal is If the indication information is received, the terminal may determine that the terminal has the right to access the cell according to the second cell, that is, the first cell is in a state of allowing access to the terminal, The terminal may reside in the second cell, so that the terminal can normally camp and access the first cell, that is, the cell of the access network device only allows the RAT type supported by the terminal to be satisfied.

Through the core network node pool shown in this embodiment, when the terminal roams in the target pool area, the core network node serving the terminal is always located in the core network node pool, and passes through the core. When the network node pool provides the roaming service for the terminal, the signaling interaction between the core network nodes caused by the change of the core network node may be reduced, and the first identifier shown in this embodiment is further used to identify the A pool of core network nodes, such that the terminal determines the pool of core network nodes serving the terminal.

Optionally, if the first cell is connected to multiple core network nodes, if multiple core network nodes connected to the first cell belong to the same core network node pool, multiple core network nodes may be used. Corresponding to the same first identifier, for example, the first cell is connected to multiple EPC nodes, and multiple EPC nodes belong to the same core network node pool, and multiple EPC nodes correspond to the same first identifier.

If the plurality of core network nodes connected to the first cell belong to different node pools, the different node pools connected to the first cell correspond to different first identifiers.

For example, the first cell is connected to multiple EPC nodes, and the plurality of EPC nodes belong to different first core network node pools and second core network node pools, then the first core network node pool and the second core network The node pool corresponds to different first identifiers.

In the wireless communication system provided by the present application, usually different service providers provide different core network nodes for operation, and the core network can be operated by different operators through a public land mobile network (PLMN). The node performs identification. It can be seen that the PLMN corresponds to at least one core network node, and different PLMNs are used to indicate different operators. The terminal can determine the core network nodes operated by different operators through the PLMN.

The indication information shown in this embodiment may include a second identifier list, where the second identifier list includes at least one second identifier, where the second identifier is used to correspond to a target PLMN, where the target PLMN is The PLMN supported by the first cell.

Specifically, the access network device may pre-create a corresponding relationship between the PLMN and the identifier, where the access network device may acquire the core connected to the access network device in the process of generating the indication information. a network node, which in turn obtains a target PLMN corresponding to the core network node to which the access network device is connected, and determines the corresponding to the target PLMN according to a predetermined correspondence between the different PLMN and the identifier. The second logo.

The second identifier may identify the PLMN supported by the first cell by using a character, and the description of the character is as described above, and is not described in detail in this embodiment.

Optionally, if the first cell supports multiple target PLMNs, the second identifier list includes multiple different second identifiers, and different second identifiers correspond to different target PLMNs. .

Optionally, if the multiple target PLMNs supported by the first cell are all corresponding to the same core network, the indication information may include only one of the first identifiers, where the first identifier is Corresponding to the plurality of the second identifiers in the second identifier list, the first identifier included in the indication information may be used to indicate multiple target PLMNs supported by the first cell.

For example, the type of the RAT supported by the first cell is 4G, and the first target PLMN and the second target PLMN supported by the first cell are both connected to the same core network EPC. At this time, the structure of the indication information Can be:

In a first example, the indication information includes a first identifier and a second identifier;

Specifically, the first identifier may be a character “4G”, so that the terminal can determine, according to the first identifier, a type of the RAT supported by the first cell;

The indication information further includes a second identifier corresponding to the first target PLMN and a second identifier corresponding to the second target PLMN, and a second identifier corresponding to the first target PLMN and the The second identifiers corresponding to the second target PLMNs are different from each other;

In a second optional example, the indication information includes the first identifier and the second identifier;

For the specific description of the first identifier, please refer to the first example shown in the above, and the details are not described in detail; the indication information further includes a second identifier corresponding to the first target PLMN and the foregoing a second identifier corresponding to the second target PLMN, and the second identifier corresponding to the first target PLMN and the second identifier corresponding to the second target PLMN are the same identifier;

The third optional example that the indication information includes only the first identifier;

Specifically, the first identifier may be used to indicate the RAT type supported by the first cell, and the specific description is shown in the first example shown in the foregoing, and details are not described herein;

The first identifier may also be used to indicate the first target PLMN and the second target PLMN. The specific description of the first identifier for indicating the target PLMN is as described above, and details are not described herein.

Optionally, the indication information that is displayed in this embodiment may further include a third identifier, where the third identifier is a cell identifier when the first cell accesses a type of a RAT supported by the first cell.

Specifically, if the indication information is used to indicate that the type of the RAT that the first cell accesses is one type, the third identifier is a cell identifier when the cell accesses the type of the RAT, for example, If the indication information is used to indicate that the type of the RAT that the first cell accesses is 4G, the third identifier is a cell identifier when the first cell accesses 4G, such as the third identifier. It is an e-utran cell global identifier (ECGI).

Specifically, if the indication information is used to indicate that the type of the RAT that the first cell accesses is multiple, the indication information may include multiple third identifiers, and different third identifiers are used. And identifying a type of different RATs accessed by the first cell.

For example, in this embodiment, the type of the RAT that the first cell accesses is 4G and 5G, and the indication information is used to indicate that the type of the RAT that the first cell accesses is 4G. And 5G, the structure of the indication information at this time may be:

The indication information includes the first identifier and/or the second identifier. For details of the first identifier and the second identifier, please refer to the foregoing embodiment, and details are not described herein;

The indication information further includes a third identifier list, where the third identifier list includes two third identifiers, where one third identifier is used to identify a cell identifier when the first cell accesses 4G, and another third identifier The identifier is used to identify a cell identifier when the first cell accesses 5G.

Optionally, in this embodiment, the content included in the plurality of the third identifiers may be the same.

For example, when the type of the RAT that the first cell accesses is 4G and 5G, it is used to indicate that the type of the RAT that the first cell accesses is 4G, and is used to indicate the first cell. When the third identifier of the type of the RAT that is accessed is 5G, the content of the third identifier is the same, and the access network device only needs to send a third identifier to the terminal.

Optionally, in this embodiment, the content included in the multiple identifiers may be different;

For example, in a case where the type of the RAT that the first cell accesses is 4G and 5G, the third identifier when the type of the RAT that the first cell accesses is 4G and is used to indicate the When the type of the RAT that is accessed by the first cell is 5G, the third identifier is different, and the access network device may send the two third identifiers that are different from each other to the terminal, that is, used to indicate that the first cell is accessed. The third identifier when the type of the RAT is 4G and the third identifier when the type of the RAT that the first cell accesses is 5G.

Optionally, the third identifier when the type of the RAT used to indicate the access of the first cell is 4G and the third identifier when the type of the RAT used to indicate the access of the first cell is 5G is different. The third identifier that is used to indicate that the type of the RAT that the first cell accesses is 5G may be corresponding to the third identifier when the type of the RAT that the first cell accesses is 4G. Obtain;

Specifically, since the cell supporting the RAT type is 5G, the cell includes many high-frequency cells, and the coverage of the high-frequency cell is relatively small. Therefore, the number of cells supporting 5G is relatively large, and different cell configurations for different 5Gs are supported. The third identifier may be used to indicate the first cell. In this embodiment, the third identifier when the type of the RAT that is used by the first cell is 5G may be used to indicate the first cell. The third identifier of the type of the accessed RAT is 4G plus a prefix to indicate.

For example, the character included in the third identifier when the type of the RAT that is used to indicate the access of the first cell is 4G may be 28-bit bit size data, and is used to indicate the first The third identifier when the type of the RAT accessed by the cell is 5G may be preceded by an 8-bit prefix in the data of the 28-bit bit size.

It should be clarified that the specific length of the character included in the third identifier when the type of the RAT that the first cell accesses is 4G is not limited, and the pair is used to indicate the The length of the prefix added before the third identifier of the type of the RAT that is accessed by the cell is not limited, as long as the third identifier can identify the identifier of the first cell when accessing the type of each RAT. can.

It should be further clarified that, in this embodiment, the third identifier when the type of the RAT used to indicate the access of the first cell is 5G is specifically according to the type of the RAT used to indicate the access of the first cell. The description of the third identifier corresponding to the 4G is an optional example, which is not limited. For example, the third identifier when the type of the RAT used to indicate the access of the first cell is 5G may also be used for indication. The third identifier when the type of the RAT accessed by the first cell is 4G is represented by a suffix.

Optionally, the indication information shown in this embodiment further includes tracking area identifier (TAI) information, where the tracking area identification information is used to indicate that the first cell is connected to a different core network node. The tracking area, wherein the tracking area generally represents a range of paging the terminal, and one tracking area may include a plurality of cells, and the network side pages the terminal within a cell range of the tracking area corresponding to the tracking area identifier.

It can be understood that the tracking area has different names in different types of RATs, such as a location area, a routing area, and the like, which are not limited by the present invention.

If the different core network nodes connected to the first cell correspond to different tracking area identification information, the indication information includes tracking area identification information corresponding to each core network node respectively connected to the first cell. .

And if the different core network nodes connected to the first cell correspond to the same tracking area identifier information, the indication information includes tracking area identifier information corresponding to all core network nodes connected to the first cell.

If the type of the RAT supported by the terminal is different from the type of the RAT supported by the first cell, if the terminal still resides in the first cell, the terminal resides in the first A radio resource control (RRC) connection is initiated in the cell, until the core network node accessed by the access network device finds that the terminal cannot access the first cell, and the core network node If the terminal is refused or released, the signaling overhead is caused in the process, which reduces the efficiency of the terminal accessing the cell. To reduce the signaling overhead and improve the efficiency of the terminal accessing the cell, the embodiment is as shown in this embodiment. The indication information may be used to indicate that the terminal that meets the target condition accesses the first cell, where the target condition is that the type of the RAT supported by the terminal is the same as the type of the RAT supported by the first cell.

In this embodiment, the type of the RAT supported by the first cell is used as an example of the type of the first RAT and the type of the second RAT, where the type of the first RAT is 4G, and the connected core network is used. For the EPC, the type of the second RAT is 5G, and the connected core network is NG-core.

In the case that the access network device determines that the type of the RAT supported by the first cell is 5G, in order to reduce signaling overhead, it is required to indicate that the terminal that does not support the NG-core system cannot access the RAT. The first cell, the access network device may set a first information element (IE) and a second cell in the indication information, where the first cell is used to indicate the first cell The state of the cell is a forbidden access state for the type of the first RAT, and the second cell is used to indicate that the state of the first cell is an allowed access state for the type of the second RAT.

If the type of the RAT supported by the terminal is the type of the first RAT, and the terminal does not support the type of the second RAT, the terminal does not have the capability of reading the second cell. The terminal can only read the first cell, and the terminal can determine, according to the first cell, that the terminal cannot access the first cell, that is, the first cell is connected to the terminal. In the case of a state in which access is prohibited, the terminal does not camp in the first cell, thereby avoiding the fact that a terminal of a type that does not support the first RAT resides in the first cell. Signaling overhead.

If the type of the RAT supported by the terminal is the type of the second RAT, the terminal may ignore the first cell, and the terminal reads the second cell, where the terminal may The second cell determines that the terminal can access the first cell, that is, the first cell supports an access state of the terminal, and supports the terminal of the second RAT type. , can normally camp and access the first cell.

It can be seen that, as shown in this embodiment, the first cell only allows the terminal that satisfies the target condition to camp and access, thereby avoiding that the terminal that does not meet the target condition resides in the The signaling brought by the first cell is happy, which effectively improves the efficiency of the terminal accessing the cell.

Optionally, if the access network device shown in this embodiment sends the indication information to the terminal by using a system message of the first cell, the access network device is in the first cell. The first cell and the second cell are set in a system message.

In the process of the cell initiating the cell reselection, the terminal may select the neighboring cell of the first cell to access, for example, if the first cell carries too many terminals and congestion occurs. The terminal may initiate a cell reselection process. If the signal quality of the neighboring cell of the first cell is better than the signal quality of the first cell, the terminal may initiate a cell reselection process. The reason why the terminal initiates the cell reselection is not limited in this embodiment. The following describes how to improve the efficiency of the cell reselection by the terminal information provided in this embodiment:

The indication information shown in this embodiment is used to indicate a type of a RAT supported by the second cell, where the second cell is a neighboring cell of the first cell.

Specifically, the indication information may be used to indicate frequency point information of the second cell, and the frequency point information of the second cell may indicate a frequency range covered by the second cell.

Optionally, the indication information is used to indicate a type of the RAT supported by the second cell, where the indication information indicates a specific manner of a type of the RAT supported by the second cell, as shown in the foregoing. The indication information indicates the specific manner of the type of the RAT supported by the first cell, and details are not described herein.

Step 202: The access network device sends the indication information to the terminal.

The access network device shown in this embodiment may periodically send the indication information to the terminal.

Optionally, the access network device may send the indication information to the terminal by using a system message of the first cell.

Step 203: The terminal receives the indication information.

Step 204: The terminal acquires preset information.

In this embodiment, the terminal may select a cell to be accessed by the terminal according to the preference of the terminal to the cell. Specifically, the terminal may pre-store the preset information, where the preset information is used to indicate the The type that the terminal prefers, that is, the type of RAT that the terminal is to access.

Specifically, the type of the RAT indicated by the preset information may be one type or multiple types.

Step 203 to step 204 shown in this embodiment are not limited to the sequence of execution timings, as long as the terminal obtains the indication information and the preset information, step 205 is performed.

Step 205: The terminal determines a target cell.

Specifically, the terminal shown in this embodiment determines the target cell according to the indication information and the preset information, where the target cell is a cell to which the terminal is to access.

The following describes the specific process of the terminal determining the target cell:

If the terminal determines that the cell indicated by the indication information is a cell that is preferred by the terminal, the terminal may determine that the cell indicated by the preset information is the target cell.

Specifically, the case that the cell indicated by the indication information is a cell that is preferred by the terminal may be as follows:

The indication information indicates the type of the RAT supported by the first cell, and the type of the RAT supported by the first cell indicated by the indication information and the type of the RAT indicated by the preset information the same;

Or the indication information indicates that the type of the RAT supported by the first cell and the type of the RAT supported by the second cell, and the type of the RAT supported by the first cell indicated by the indication information The same type as the RAT indicated by the preset information;

Or the indication information indicates that the type of the RAT supported by the first cell and the type of the RAT supported by the second cell, and the type of the RAT supported by the first cell indicated by the indication information And the type of the RAT supported by the second cell is the same as the type of the RAT indicated by the preset information;

In the above case, the terminal may determine whether the first cell indicated by the indication information meets a cell selection criterion, and if yes, the terminal may determine that the first cell is the target cell.

Specifically, the cell selection criterion is an S criterion.

More specifically, if the terminal determines that when Srxlev>0, the terminal may determine that the first cell meets a cell selection criterion;

Among them, the formula of Srxlev is as follows:

Srxlev=Qrxlevmeas-Qrxlevmin-Pcompensation;

Wherein, Qrxlevmeas refers to the signal quality value of the pilot channel measured by the terminal, Qrxlevmin is the minimum received power required by the first cell, and the terminal can read the Qrxlevmin from the system broadcast message; Pcompensation is a compensation value, which can be passed The following formula is calculated:

Pcompensation=max(UE_TXP-WR_MAX_RACH-P_MAX, 0);

The UE_TXPWR_MAX_RACH is the maximum transmission power of the terminal on a random access channel (RACH) during random access, and the UE_TXPWR_MAX_RACH is sent by a system broadcast message, generally set to 0, and P_MAX is the maximum output of the terminal. power.

Alternatively, the indication information indicates that there is a type of the RAT supported by the second cell, and the type of the RAT supported by the second cell indicated by the indication information is indicated by the preset information. The type of the RAT is the same. Because the first cell is not the cell preferred by the terminal, the terminal may reselect the access from the first cell to the second cell according to the cell reselection criterion.

Specifically, the cell reselection criterion may be an R criterion.

More specifically, if the terminal determines that the second cell meets the cell reselection criterion, the terminal may perform cell reselection to determine that the target cell is the second cell.

Wherein, the R criterion is:

Rs=Qmeas_s+Qhysts;

Rn=Qmeas_n–Qoffsets_n;

Where: Qmeas_s is the received signal quality measurement value of the first cell, Qmeas_n is the received signal quality measurement value of the second cell; Qhysts is the cell reselection hysteresis; Qoffsets_n is the difference of the received signal quality requirements of the first cell and the second cell.

Specifically, if the terminal determines that the continuously measured Rn and Rs can maintain Rn>Rs within the detection time, the reselection is required, that is, the terminal can determine that the target cell is the Two cells.

Alternatively, the indication information indicates that there is a type of the RAT supported by the first cell, and the type of the RAT supported by the first cell indicated by the indication information is related to the RAT indicated by the preset information. The same type;

In the above case, the terminal may determine whether the signal strength and/or the signal quality of the first cell is greater than a preset threshold;

If yes, the terminal may determine that the target cell is the first cell if the signal strength and/or the signal quality of the first cell is greater than a preset threshold.

In this embodiment, the size of the preset threshold is not limited, as long as the signal strength and/or the signal quality of the first cell is greater than the preset threshold, the terminal may be normal in the first cell. Start the business.

Alternatively, the indication information indicates that there is a type of the RAT supported by the first cell and a type of the RAT supported by the second cell, and the RAT supported by the first cell indicated by the indication information The type of the RAT supported by the second cell is the same as the type of the RAT indicated by the preset information;

Or the indication information indicates the type of the RAT supported by the second cell, and the type of the RAT supported by the second cell indicated by the indication information and the RAT indicated by the preset information. The same type;

In the above case, if the terminal determines that the signal strength and/or the signal quality of the first cell is less than or equal to a preset threshold, the terminal may determine that the target cell is the a second cell, such that the terminal reselects from the first cell to the second cell.

Alternatively, if the terminal determines that the cell indicated by the indication information is not the cell that the terminal prefers, the terminal may determine that the cell indicated by the indication information is the target cell.

Specifically, if the cell indicated by the indication information is not a cell that is preferred by the terminal, the indication information indicates that the type of the RAT supported by the first cell and/or the RAT supported by the second cell If the type of the RAT indicated by the indication information is different from the type of the RAT indicated by the preset information, the terminal determines, according to the indication information and the preset information, If the terminal is unable to access a cell that does not match its own preference, the terminal may initiate a cell reselection criterion to attempt to access other cells not indicated by the indication information.

As shown in the above, the terminal shown in this embodiment may select a cell to be accessed according to the preference of the terminal itself, and the indication information indicates the type of the RAT of the first cell and the second cell. In the case of the type of the supported RAT, the terminal may select a cell to be accessed between the first cell and the second cell according to the preference of the terminal, which may simplify the efficiency of the terminal accessing the cell and reduce The complexity of the cell reselection by the terminal improves the efficiency of the terminal for cell reselection.

Step 206: The terminal accesses the target cell.

In this embodiment, in a case that the terminal determines the target cell, the terminal may reside in the target cell, and after the terminal successfully resides in the target cell, the terminal Services may be initiated and received, such as a random access procedure to access the target cell.

With the access method shown in this embodiment, the access network device may send indication information indicating the type of the RAT supported by the first cell and/or the second cell to the terminal, so that the terminal has determined that the terminal needs to be connected. The cell is accessed in the case of the type of the RAT supported by the incoming cell, thereby avoiding the situation that the type of the RAT supported by the terminal does not match the type of the RAT supported by the cell, thereby effectively preventing the terminal from successfully accessing the cell. The situation improves the efficiency of the terminal accessing the cell.

For a better understanding of the access method shown in the present invention, the specific implementation process of the access method provided by the present invention is described in detail below in conjunction with a specific application scenario:

First, please refer to FIG. 3 , where FIG. 3 is a schematic structural diagram of a wireless communication system according to the present invention in an application scenario.

As shown in FIG. 3, in the application scenario, the wireless communication system includes an access network device 301, and the specific description of the access network device 301 is shown in the embodiment shown in FIG. There is no limit in the middle.

The wireless communication system further includes at least one terminal. For details of the terminal, please refer to the embodiment shown in FIG. 1 , which is not described in the application scenario.

The wireless communication system further includes an EPC core network and an NG-core core network. For details of the EPC core network and the NG-core core network, please refer to the embodiment shown in FIG. 1 , which is not described in this embodiment. .

Specifically, in this application scenario, the cell of the access network device 301 is connected to the EPC core network and the NG-core core network as an example for example, and the cell of the access network device 301 is supported by the cell. The types of RATs are 4G and 5G.

More specifically, when the cell of the access network device 301 is connected to the EPC core network, the corresponding air interface technology is long term evolution (LTE), and the EPC core network and the access network device 301 The interface between them is the S1 interface.

When the cell of the access network device 301 is connected to the NG-core core network, the corresponding air interface technology is NR (New Radio), and the interface between the NG-core core network and the access network device 301 For the Ng1 interface.

Based on the wireless communication system shown in FIG. 3, the specific process of the terminal accessing the cell shown in this application scenario is described below with reference to FIG. 4:

Step 401: The terminal accesses a cell of the access network device.

The specific process of the terminal shown in this application scenario for accessing the cell of the access network device 301 is shown in the embodiment shown in FIG. 2 , and details are not described in this application scenario.

Step 402: The terminal registers with the target core network.

In the application scenario, the process in which the terminal can access the cell of the access network device 301, and the terminal accesses the cell of the access network device 301, refer to the embodiment shown in FIG. 2, specifically This application scenario is not described in detail.

As shown in FIG. 3, the first terminal 302, the second terminal 303, and the third terminal 304 are connected to the cell of the access network device 301. In the application scenario, the first terminal is used. The RAT type supported by the 302 is 4G, and the target core network registered by the first terminal 302 is an EPC core network; the RAT type supported by the second terminal 303 is 5G, and the second terminal 303 is registered. The target core network is the NG-core core network; the third terminal 304 supports the RATs of the type 4G and 5G, and the target core network registered by the third terminal 304 is the EPC core network and the NG-core core network. .

In the case where the terminal of the access network device 301 is connected to a terminal supporting multiple RAT types, how to implement the paging process for the terminal is described in the following steps.

Step 403: The access network device receives a first paging message sent by the target core network.

Specifically, the target core network shown in the application scenario may initiate paging to the terminal by using the first paging message.

Taking the first terminal 302 as an example, the EPC core network that is the target core network may initiate paging to the first terminal 302 by using the first paging message, where the second terminal 303 is For example, the NG-core core network that is the target core network may initiate paging to the second terminal 303 by using the first paging message, taking the third terminal 304 as an example, as the target. The EPC core network of the core network and the NG-core core network may simultaneously initiate paging to the third terminal 304 by using the first paging message.

The target core network may set an identifier of the terminal to be paged by the target core network in the first paging message.

This application scenario is exemplified by the example that the EPC core network initiates paging to the second terminal 303 as an example:

When the EPC core network needs to initiate paging to the second terminal 303, the EPC core network may send the first paging message to the access network device 301.

The EPC core network is configured to successfully page the second terminal 303, and the EPC core network may set the identifier of the second terminal 303 in the first paging message.

It can be seen that the access network device 301 shown in this application scenario can receive a first paging message for initiating paging to different terminals, and different first paging messages include different terminals. Logo.

Step 404: The access network device sends a second paging message to the terminal.

Specifically, the access network device 301 can calculate a time of the second paging message sent by the air interface according to the terminal identifier in the first paging message.

If the access network device 301 receives a plurality of different first paging messages for paging different terminals, the access network device 301 may calculate, according to each of the first paging messages, respectively. And sending, by the air interface, the second paging message, and combining the first paging messages that are to be sent in the air interface at the same time into one second paging message.

Specifically, the second paging message includes an identifier of the terminal carried in the first paging message.

Optionally, the access network device 301 can be based on a source of the first paging message, such as a paging from the NG-core core network, or a paging from an EPC core network, in the second The paging message carries core network identification information indicating the source of the first paging message, so that the identifier of the terminal in the second paging message is in one-to-one correspondence with the core network identifier.

For example, if the access network device 301 determines that the source of the first paging message is the core network NG-core, the second paging message may be configured to indicate the core network NG-core. Core network identification information, such as the character "NG-core", the identifier of the second terminal in the second paging message is the character "UE2", and the identifier of the second terminal in the second paging message UE2" has a one-to-one correspondence with the core network identifier "NG-core".

Optionally, the access network device 301 may set a default core network identifier information in the second paging message, that is, when the second paging message does not carry the core network identifier information. The source of the first paging message representing the paging terminal is from the set default core network.

For example, if the access network device 301 determines that the source of the first paging message is the core network NG-core, the default setting of the second paging message is used to indicate the core network NG- The core network identifier information of the core, the second paging message used for paging the second terminal includes the identifier “UE2” of the second terminal, and does not include the core network identifier used to indicate the core network NG-core. information.

It can be seen that if the core paging information of the NG-core core network is not included in the second paging message, the representative paging is from the NG-core core network, if the second paging message does not include the EPC core. When the core network of the network identifies information, it means that the paging comes from the EPC core network.

The advantage of the way of indicating the source of the paging by setting the default core network identification information for indicating the NG-core core network will become more and more obvious. When all the cells are connected to the NG-core core network, the second paging message does not need to carry any core network identifier.

Optionally, if the access network device 301 determines that the terminal is only registered to one core network, the access network device 301 may not set the core network identification information in the second paging message. And the terminal determines the registered core network.

The following is an example of the terminal being the second terminal 303, and the second terminal 303 is specifically configured to establish a signaling path with the NG-core core network:

Step 405: The terminal sends one or more information included in the second paging message to the target non-access stratum.

Specifically, the one or more information included in the second paging message may be: an identifier of the terminal and/or the core network identifier information.

More specifically, if the terminal receives the second paging message, if the second paging message includes the identifier of the terminal, the terminal may have its own paging, and the terminal may Determining the source of the paging based on the second paging message.

For example, if the second paging message includes the core network identification information, the terminal may determine the source of the paging according to the core network identification information.

Taking the core network identification information included in the second paging message as the identifier “NG-core” as an example, the terminal can determine that the source of the paging is the NG-core core network.

For another example, the terminal may determine the source of the paging according to the default core network identification information in the second paging message.

Taking the core network identification information of the NG-core core network not included in the second paging message as an example, the terminal can determine that the source of the paging is the NG-core core network.

Optionally, the terminal may be registered to only one core network. When the terminal is only registered to one core network, the second paging message may not carry any core network identification information, and the terminal registers according to itself. The situation identifies the core network to which it is registered.

For example, if the second paging message does not carry any core network identification information, if the terminal determines that it only registers with the NG-core core network, the terminal can determine the paging. The source is the NG-core core network.

When the terminal determines the target core network of the paging source, the terminal may send the second paging message to a target non-access stratum (NAS) of the target core network.

For example, when the terminal determines that the target core network of the paging source is the NG-core core network, the terminal may send the second paging message to the NAS of the NG-core core network to establish a A signaling path between the terminal and the NG-core core network.

It can be seen that, as shown in the application scenario, the terminal can prepare to identify the source of the paging, and send the second paging message to the corresponding NAS, thereby improving the efficiency of establishing the signaling path, and effectively reducing air interface resources. Occupy.

Optionally, the second paging message shown in the application scenario may also be used to notify a change of a system message.

Specifically, the cell of the access network device shown in this application can access the core network of multiple standards. When the system message changes, the terminal needs to be notified to receive a new system message, because different terminals are registered to different standards. The core network needs to receive different system messages. The following is how the second paging message shown in this application scenario implements the terminal receiving the changed system message sent by the core network registered by itself;

Specifically, the second paging message shown in the application scenario is configured with multiple target IEs, and different target IEs correspond to different core networks connected to the cells of the access network device, where the target The IE is configured to notify that the system message sent by the core network corresponding to the target IE is changed, and when the terminal receives the target IE included in the second paging message, the terminal re-receives A system message sent by a core network corresponding to the target IE.

For example, the application scenario is that the core network connected to the access network device is an EPC core network and an NG-core core network, and the first target IE corresponds to the EPC core network, that is, the first target IE is used. The system message of the NG-core core network is changed, and the second target IE is used to notify the NG-core core network that the system message is changed.

For the format of the second system message, as shown in FIG. 5, as shown in FIG. 5, the target parameter CommonSI is used to indicate that the UE is camped on the cell of the access network device or initiates a service regardless of which core network the terminal registers with. All the required messages, such as the configuration information of an air interface public resource.

If the core network that is registered by the terminal is an EPC core network, if the first target IE is included in the second paging message, the terminal may determine according to the first target IE. If the system message sent by the EPC core network registered by the terminal is changed, the terminal re-receives the system message sent by the EPC core network according to the first target IE, if the second paging message The second target IE is included in the terminal, and the terminal registered to the EPC core network ignores the second target IE.

If the core network registered by the terminal is an NG-core core network, if the second paging message includes the first target IE, the terminal registered to the NG-core core network ignores the The first target IE, if the second paging message includes the second target IE, the terminal may determine, according to the second target IE, the NG-core core network registered by the terminal The transmitted system message is sent, and the terminal re-receives the system message sent by the NG-core core network according to the second target IE.

It can be seen that, by using the second paging message shown in the application scenario, the terminal only receives the changed system message sent by the core network registered by itself, thereby effectively preventing the terminal from receiving an unnecessary system. In the case of a message, the action of the terminal to receive unnecessary system messages is reduced, thereby avoiding the power consumption caused by the terminal receiving the system message that it does not need.
