In the feelings of the Type-Inconsistencies for the RAT that the type for the RAT that the terminal is supported and the first community are supported Under condition, if the terminal still resides in the first community, terminal, which resides in, can initiate radio resource in the first community (radio resource control, RRC) connection is controlled, until the core net node discovery that the access network equipment is accessed The terminal can not access the first community, and the core net node just can be refused or be discharged to the terminal, mistake It will lead to signaling overheads in journey, so that the efficiency of terminal access cell is reduced, to reduce signaling overheads, to promote terminal access The efficiency of cell, then instruction information shown in the present embodiment may be used to indicate meet goal condition terminal access it is described first small Area, wherein the class for the RAT that the type and the first community for the RAT that the goal condition is supported by the terminal are supported Type is identical.

The type for the RAT that the present embodiment is supported with the first community is the type of the first RAT and the type of the 2nd RAT For illustrate, wherein the type of the first RAT is 4G, and the core net of connection is EPC, the 2nd RAT's Type is 5G, and the core net of connection is NG-core.

In the case where the access network equipment determines that the type for the RAT that the first community is supported is 5G, for drop Low signaling overheads then needs to be indicated to and does not support the terminal of NG-core standard that can not access the first community, then described to connect The first cell (information element, IE) and the second cell can be arranged in log equipment in the instruction information, In, first cell is used to indicate the state of the first community and forbids access state, institute for the type for the first RAT It states the second cell and is used to indicate the state of the first community as the permission access state of the type for the 2nd RAT.

If the type for the RAT that the terminal is supported is the type of the first RAT, and the terminal does not support described the The type of two RAT, the terminal do not have the ability for reading second cell, and the terminal is merely able to read first letter Member, then the terminal can determine that the terminal cannot access the first community according to first cell, i.e., described One cell forbids the state of access for the terminal, then the terminal will not reside in first community, to avoid The terminal of the type of the first RAT is not supported to reside in brought signaling overheads in the first community.

If the type for the RAT that the terminal is supported is the type of the 2nd RAT, the terminal can be ignored described the One cell, the terminal read second cell, and the terminal can determine that the terminal can connect according to second cell Enter the first community, i.e., the described first community to allow access state, then supports the 2nd RAT's for the terminal The terminal of type normally can be resident and access the first community.

As it can be seen that the first community only can allow to meet the terminal of the goal condition using shown in the present embodiment Resident and access resides in brought in the first community so as to avoid the terminal for being unsatisfactory for the goal condition Signaling is happy, effectively improves the efficiency of terminal access cell.

Optionally, if the instruction information is passed through the first community by the access network equipment shown in the present embodiment System message is sent to the terminal, then the access network equipment is arranged described first in the system message of the first community Cell and second cell.

It is initiated in cell reselection process in the terminal, the terminal can select the neighboring community of the first community to carry out Access, for example, the terminal can be initiated in the case where the first community carries excessive terminal to which congestion have occurred Cell reselection process, for another example, the signal quality of the neighboring community of the first community are better than the signal quality of the first community In the case where, the reason of terminal can initiate cell reselection process etc., and the present embodiment initiates cell reselection to the terminal, is not It limits, the efficiency for how improving the terminal progress cell reselection to instruction information provided by the present embodiment below is shown Example property explanation:

The instruction information shown in the present embodiment is used to indicate the type for the RAT that second community is supported, wherein described Second community is the neighboring community of the first community.

Specifically, the instruction information may be used to indicate the frequency point information of the second community, the frequency of the second community Point information can indicate that the frequency range that the second community is covered.

Optionally, the instruction information is used to indicate the type for the RAT that the second community is supported, wherein the finger The concrete mode for showing the type for the RAT that information indicates that the second community is supported, refer to it is above-mentioned shown in instruction letter Breath indicates the concrete mode of the type for the RAT that the first community is supported, does not repeat them here specifically.

The instruction information is sent to the terminal by step 202, the access network equipment.

The instruction information periodically can be sent to the terminal by the access network equipment shown in the present embodiment.

Optionally, the instruction information can be sent to by the access network equipment by the system message of the first community The terminal.

Step 203, the terminal receive the instruction information.

Step 204, the terminal obtain presupposed information.

In the present embodiment, the terminal can select the terminal cell to be accessed based on preference of the terminal itself to cell, Specifically, the terminal can be previously stored with the presupposed information, it is preferred that the presupposed information is used to indicate the terminal, The type of the i.e. described terminal RAT to be accessed.

Specifically, the type of RAT indicated by the presupposed information can be a seed type or multiple types.

Without the successive restriction executed in timing between step 203 to step 204 shown in the present embodiment, as long as the terminal In the case where getting the instruction information and the presupposed information, step 205 is executed.

Step 205, the terminal determine Target cell.

Specifically, the terminal shown in the present embodiment is according to the instruction information and presupposed information determination Target cell, the Target cell are the terminal cell to be accessed.

The detailed process of the Target cell, which is illustrated, to be determined to the terminal below:

It is described if the terminal determines that cell indicated by the instruction information is the preferred cell of the terminal Terminal can determine that cell indicated by the presupposed information is the Target cell.

Specifically, cell indicated by the instruction information can be following institute the case where being the terminal preferred cell Show several situations:

One kind, the type for the RAT that the instruction information instruction has first community to be supported, and indicated by the instruction information The type of RAT supported of the first community it is identical as the type of RAT indicated by the presupposed information；

Or, the type and the second community of the RAT that the instruction information instruction has first community to be supported are supported RAT type, and the type of RAT supported of the first community indicated by the instruction information and the default letter The type of the indicated RAT of breath is identical；

Or, the type and the second community of the RAT that the instruction information instruction has first community to be supported are supported RAT type, and the type and described second of RAT that the first community indicated by the instruction information is supported The type for the RAT that cell is supported is identical as the type of RAT indicated by the presupposed information；

In these cases, the terminal can determine whether first community indicated by the instruction information meets cell choosing Criterion is selected, if so, the terminal can determine that the first community is the Target cell.

Specifically, the cell selection criterion is S criterion.

More specifically, if the terminal determines that, as Srxlev > 0, the terminal can determine that the first community Meet cell selection criterion；

Wherein, Srxlev calculation formula is as follows:

Srxlev=Qrxlevmeas-Qrxlevmin-Pcompensation；

Wherein, Qrxlevmeas refers to that the signal quality value for the pilot channel that terminal measures, Qrxlevmin are first small The minimal detectable power that area needs, the terminal can read the Qrxlevmin from system broadcast message； Pcompensation is offset, can be calculated by following formula:

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

Wherein, UE_TXPWR_MAX_RACH be the terminal in random access in random access channel (random Access channel, RACH) on it is maximum send power, UE_TXPWR_MAX_RACH is sent by system broadcast message, generally It is set as the peak power output that 0, P_MAX is the terminal.

Another kind, the type for the RAT that the instruction information instruction has the second community to be supported, and believe in the instruction The type for the RAT that the indicated second community of breath is supported is identical as the type of RAT indicated by the presupposed information, because The first community is not the preferred cell of terminal, then the terminal can be small from described first according to cell reselection criterion Area's gravity treatment is linked into the second community.

Specifically, the cell reselection criterion can be R criterion.

More specifically, described if in the case that the terminal determines that the second community meets cell reselection criterion Terminal can carry out cell reselection with the determination Target cell as the second community.

Wherein, the R criterion are as follows:

Rs=Qmeas_s+Qhysts；

Rn=Qmeas_n-Qoffsets_n；

Wherein: Qmeas_s is first community received signal quality measured value, and Qmeas_n is that second community receives signal matter Measurement；Qhysts is that cell reselection is sluggish；Qoffsets_n is first community and the requirement of second community received signal quality Difference.

Specifically, if the terminal is determined, if the Rn and Rs that continuously measure can when detecting in all keep Rn > Rs, then need gravity treatment, i.e., the described terminal can determine that the Target cell is the second community.

Another kind, the type for the RAT that the instruction information instruction has first community to be supported, and the instruction information is signified The type for the RAT that the first community shown is supported is identical as the type of RAT indicated by the presupposed information；

In these cases, the terminal can determine whether the signal strength of the first community and/or signal quality are big In preset threshold；

If so, the terminal can determine that, it is greater than in the signal strength and/or signal quality of the first community pre- If in the case where threshold value, the Target cell is the first community.

The present embodiment to the size of the preset threshold without limitation, as long as in the signal strength and/or letter of first community In the case that number quality is greater than the preset threshold, the terminal can in the first community normal initiation business.

Another kind, the type for the RAT that the instruction information instruction has first community to be supported and second community institute The type of the RAT of support, and the type of RAT supported of the first community indicated by the instruction information and described The type for the RAT that second community is supported is identical as the type of RAT indicated by the presupposed information；

Or, the type for the RAT that the instruction information instruction has the second community to be supported, and in instruction information institute The type for the RAT that the second community indicated is supported is identical as the type of RAT indicated by the presupposed information；

In these cases, the terminal is less than in the signal strength and/or signal quality for determining the first community Or in the case where being equal to preset threshold, then the terminal can determine that the Target cell is the second community, so that institute It states terminal and is linked into the second community from the first community gravity treatment.

Another kind, if the terminal determines that cell indicated by the instruction information is not preferred small of the terminal Area, then the terminal can determine that cell indicated by the instruction information is the Target cell.

Specifically, in the case that cell indicated by the instruction information is not the preferred cell of the terminal: such as institute The type for the RAT that the type and/or second community for stating the RAT that instruction information instruction has first community to be supported are supported, and institute It states under the type of RAT indicated by instruction information and the different situation of type of RAT indicated by the presupposed information, then institute It states terminal and determines that the terminal can not be accessed according to the instruction information and the presupposed information and do not met with itself preference Cell, then the terminal can initiate cell reselection criterion and attempt described other cells that do not indicate of instruction information of access.

By it is above-mentioned shown it is found that terminal shown in the present embodiment can according to the preference of terminal itself it is selected to be accessed it is small Area, and the RAT for thering is the type of the RAT of the first community and the second community to be supported in the instruction information instruction Type in the case where, the terminal can according to the preference of terminal between the first community and the second community select institute The cell to be accessed, can simplify the efficiency of terminal access cell, and reduce the complexity that terminal carries out cell reselection, be promoted eventually End carries out the efficiency of cell reselection.

Step 206, the terminal access the Target cell.

In the present embodiment, in the case where the terminal determines the Target cell, the terminal can reside in institute State in Target cell, after the terminal successfully resides in the Target cell, business can be initiated and be received to the terminal, such as into Row random access (random access procedure) is to access to the Target cell.

Using cut-in method shown in the present embodiment, instruction can be had first community and/or second community by access network equipment The instruction information of the type of the RAT supported is sent to terminal, so that terminal is having determined that the cell to be accessed is supported RAT type in the case where access cell, thus the RAT for avoiding the type of the RAT supported by terminal and cell from being supported The unmatched situation of type improve terminal access to effectively avoid the case where terminal can not be successfully accessed cell The efficiency of cell.

Cut-in method shown in for a better understanding of the present invention, below in conjunction with concrete application scene to provided by the present invention The specific implementation procedure of cut-in method is described in detail:

Firstly, shown in Figure 3, wherein Fig. 3 is wireless communication system provided by the present invention in application scenarios Structural schematic diagram.

As shown in figure 3, the wireless communication system includes access network equipment 301, to the access in this application scene Illustrating for net equipment 301 please be detailed in embodiment shown in FIG. 1, in this application scene without limitation.

The wireless communication system further includes at least one terminal, and the illustrating of the terminal please be detailed in shown in FIG. 1 Embodiment does not repeat them here in application scenarios.

The wireless communication system further includes EPC core net and NG-core core net, the EPC core net and NG- Illustrating for core core net please be detailed in embodiment shown in FIG. 1, not repeat them here in the present embodiment.

Specifically, this application scene connects the EPC core net and institute with the cell of the access network equipment 301 simultaneously It states and illustrates for NG-core core net, then the type for the RAT that the cell of the access network equipment 301 is supported For 4G and 5G.

More specifically, when the cell of the access network equipment 301 connects the EPC core net, the corresponding technology of eating dishes without rice or wine is Long term evolution (long term evolution, LTE), and connecing between the EPC core net and the access network equipment 301 Mouth is S1 interface.

When the cell of the access network equipment 301 connects the NG-core core net, the corresponding technology of eating dishes without rice or wine is NR (New ), Radio the interface and between the NG-core core net and the access network equipment 301 is Ng1 interface.

Based on wireless communication system shown in Fig. 3, below in conjunction with illustrating that terminal shown in this application scene accesses described in Fig. 4 The detailed process of cell:

Step 401, the terminal access the cell of the access network equipment.

Terminal shown in this application scene accesses the detailed process of the cell of the access network equipment 301, please be detailed in Fig. 2 institute The embodiment shown does not repeat them here in this application scene specifically.

Step 402, the endpoint to register to target core network.

In this application scene, the terminal can access the cell of the access network equipment 301, connect described in the terminal access The process of the cell of log equipment 301, embodiment shown in Figure 2 do not repeat them here in this application scene specifically.

For as shown in Figure 3, accessing in the cell of the access network equipment 301 has first terminal 302, second terminal 303 and third terminal, wherein in this application scene, the RAT type that the first terminal 302 is supported is 4G, and described the The target core network that one terminal 302 is registered is EPC core net；The RAT type that the second terminal 303 is supported is 5G, and The target core network that the second terminal 303 is registered is NG-core core net；The third terminal 304 supports RAT's simultaneously Type is 4G and 5G, and the target core network that the third terminal 304 is registered is EPC core net and NG-core core net.

Illustrate in conjunction with shown in following steps, access, which has, in the cell of the access network equipment 301 supports a variety of RAT types Terminal in the case where, how to realize to the paging of terminal.

Step 403, the access network equipment receive the first paging message that the target core network is sent.

Specifically, the target core network shown in this application scene can be initiated by first paging message to terminal Paging.

By taking the first terminal 302 as an example, the EPC core net as the target core network can pass through described first Paging message initiates to page to the first terminal 302, by taking the second terminal 303 as an example, as the target core network The NG-core core net can be initiated to page by first paging message to the second terminal 303, whole with the third For end 304, described the can be passed through as the EPC core net of the target core network and the NG-core core net One paging message initiates to page to the third terminal 304 simultaneously.

Wherein, the target core network can be arranged what the target core network to be paged in first paging message The mark of terminal.

This application scene is illustrated so that EPC core net initiates paging to the second terminal 303 as an example:

When the EPC core net needs to initiate to page to the second terminal 303, the EPC core net can Xiang Suoshu Access network equipment 301 sends first paging message.

The EPC core net is second terminal 303 described in successful page, then the EPC core net can be sought described first Exhale the mark that the second terminal 303 is set in message.

As it can be seen that the access network equipment 301 shown in this application scene can receive for seeking to different terminal initiations The first paging message exhaled, and include different terminal iidentifications in different first paging messages.

Step 404, the access network equipment send the second paging message to the terminal.

Specifically, the access network equipment 301 can be calculated according to the terminal iidentification in first paging message in sky At the time of second paging message transmitted by mouth.

Disappear if the access network equipment 301 receives multiple different first pagings for paging different terminals Breath, then the access network equipment 301 can be calculated respectively according to each first paging message and be sought eating dishes without rice or wine to send described second At the time of exhaling message, and need to be merged into synchronization in first paging message for eating dishes without rice or wine to send one for multiple Two paging messages.

Specifically, in second paging message, comprising the mark of the terminal carried in first paging message.

Optionally, the access network equipment 301 can such as come from the NG- according to the source of first paging message The paging of core core net, or the paging from EPC core net are carried in second paging message described in being used to indicate The core network identifier information in the source of the first paging message so that the mark of the terminal in second paging message with Core network identifier corresponds.

For example, described state access network equipment 301 if it is determined that the source of first paging message is core net NG- Core, the then settable core network identifier information for being used to indicate core net NG-core, such as character in second paging message " NG-core ", second terminal in second paging message are identified as character " UE2 ", then second paging message In second terminal mark " UE2 " and core network identifier " NG-core " correspond.

Optionally, a default core network mark can be arranged in the access network equipment 301 in second paging message Know information, i.e., when not carrying the core network identifier information in second paging message, represents for call terminal Default core net of the source of one paging message from setting.

For example, described state access network equipment 301 if it is determined that the source of first paging message is core net NG- The default core network identifier information for being used to indicate core net NG-core is then arranged, then in core in second paging message It include the mark " UE2 " of second terminal in the second paging message for paging the second terminal, without including for referring to Show the core network identifier information of core net NG-core.

As it can be seen that if being represented when not including the core network identifier information of NG-core core net in second paging message Paging is from NG-core core net, if in second paging message not including the core network identifier information of EPC core net When, then paging is represented from EPC core net.

If indicating paging source by the way that the default core network identifier information for being used to indicate NG-core core net is arranged The advantage of mode can be more and more obvious.When all cells are all connected to NG-core core net, in second paging message Just do not have to carry any core network identifier.

Optionally, described to connect if the access network equipment 301 determines that the terminal is only registered in a core net Log equipment 301 can be not provided with the core network identifier information in second paging message, and be determined by the terminal The core net registered.

It is illustrated so that the terminal is the second terminal 303 as an example below, introduces the second terminal 303 Specifically how between NG-core core net to establish signaling channel:

It is non-that the one or more information for including in second paging message are sent to target by step 405, the terminal Access layer.

Specifically, one or more information included in second paging message can are as follows: the mark of the terminal and/ Or the core network identifier information.

More specifically, the terminal is in the case where receiving second paging message, if second paging message In include the terminal mark, then representing has oneself paging, and the terminal can be determined according to second paging message The source paged out.

For example, the terminal can basis if including the core network identifier information in second paging message The core network identifier information determines the source of paging.

By taking the core network identifier information that includes in second paging message is mark " NG-core " as an example, then institute It states terminal i.e. and can determine that the source of paging is NG-core core net.

For another example, the terminal can be determined according to default core network identifier information in second paging message paging come Source.

The core network identifier information with the NG-core core net not included in second paging message is Example, then the terminal is that can determine that the source of paging is NG-core core net.

Optionally, the terminal may only be registered to a core net, only be registered to core one by one in the terminal When net, any core network identifier information can not be carried in second paging message, the case where terminal is according to oneself registration is true Make be registered to core net.

For example, in the case where not carrying any core network identifier information in second paging message, if the terminal When determining that itself is only registered to NG-core core net, then the terminal is that can determine that the source of paging is NG-core core Net.

When the terminal determines the target core network in paging source, the terminal can be by second paging message It is sent to the target Non-Access Stratum (non-access stratum, NAS) of target core network.

For example, when the terminal determines that the target core network in paging source is NG-core core net, then the terminal Second paging message can be sent to the NAS of NG-core core net, to establish the terminal and the NG-core core Signaling channel between heart net.

As it can be seen that the terminal can prepare identifies the source of paging, and second is sought by shown in this application scene Message is exhaled to be sent to corresponding NAS, so that the efficiency for establishing signaling channel is improved, the effective occupancy for reducing interface-free resources.

Optionally, second paging message shown in this application scene can also be used in the change of notifying system message.

Specifically, the cell of the access network equipment shown in the application can access to the core net of multiple types, when being Unite message alteration when, need that terminal is notified to receive new system message, because different endpoint to registers is to the core of different systems Net needs to receive system message difference, is below how to realize that terminal connects to the second paging message shown in this application scene Receive the system message having changed transmitted by the core net itself registered；

Specifically, being provided with multiple target IE in second paging message shown in this application scene, and different mesh It marks IE and the different core nets that the cell of the access network equipment is connected is corresponding, the target IE is for notifying and the mesh System message transmitted by the corresponding core net of mark IE changes, then the terminal is in receiving second paging message When included target IE, then the terminal can receive system transmitted by core net corresponding with the target IE again and disappear Breath.

For example, the core net that this application scene is connected with the access network equipment is EPC core net and NG-core core For heart net, and first object IE is corresponding with EPC core net, i.e., the described first object IE is for notifying the EPC core net System message changes, and the second target IE is corresponding with NG-core core net, i.e., the described second target IE is described for notifying The system message of NG-core core net changes.

The format of the second system message can be found in shown in Fig. 5, as shown in figure 5, target component CommonSI is for referring to Show no matter endpoint to register is to which core net, resides in the cell of the access network equipment or initiates business, the message required, The configuration information of such as one public resource of eating dishes without rice or wine.

In the case where the core net that the terminal is registered is EPC core net, if including in second paging message There is the first object IE, then the terminal is the EPC core that can determine that the terminal and registered according to the first object IE System message transmitted by heart net, which is sent, to be changed, then the terminal can receive the EPC core according to the first object IE again System message transmitted by heart net is registered to EPC core if including the second target IE in second paging message Second target IE described in the terminal disregards of net.

In the case where the core net that the terminal is registered is NG-core core net, if in second paging message Include the first object IE, is then registered to first object IE described in the terminal disregards of NG-core core net, if described second It include the second target IE in paging message, then the terminal can determine that the terminal according to the second target IE System message transmitted by the NG-core core net registered, which is sent, to be changed, then the terminal is according to the second target IE meeting Again system message transmitted by the NG-core core net is received.

As it can be seen that itself being infused by second paging message shown in this application scene so that the terminal only receives The system message being had changed transmitted by the core net of volume, so that effectively avoiding terminal receives unwanted system message The case where, it reduces terminal and receives the movement of unnecessary system message, and then avoid terminal and receive itself unwanted system The power consumption that system message is brought.
