Specific embodiment

Technical solution of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments of the specification.

As shown in Figure 1, being applied in network side the present embodiment provides a kind of connection control method, comprising:

Step S101: the request of terminal access NB-IoT is received；

Step S102: the reason of sending refusal terminal access value.

Connection control method provided in this embodiment can be applied to the core net of network side, receives request and sends cause value Network element can be core net various network elements, for example, the network element can be mobile management entity (Mobility Management Entity, MME).

In the present embodiment, which is the access request of NB-IoT, can be to terminal if network side needs to refuse the request Cause value is returned to notify terminal to be denied access, and the reason of tell it to be denied access, for example, MME by NAS message come Send cause value.

Optionally, the cause value obtains limitation parameter when for being denied access for the terminal.In the present embodiment After terminal receives the cause value, limitation parameter can be obtained, there are many specific modes for obtaining limitation parameter:

The first: directly extracting limitation parameter from cause value, forbids terminal to access for example, extracting from cause value Network area etc.；

Second: going out to limit parameter according to cause value local search；For example, terminal will be local if terminal is denied access Inquire limitation parameter corresponding with cause value.

By limiting the introducing of parameter, terminal can be made when being denied access NB-IoT, no longer frequently send NB- The access request of IoT to reduce the expense for frequently accessing or measuring power consumption caused by NB-IoT and signaling, and reduces The possibility of multimode terminal ping-pong of gravity treatment between NB-IoT and other networks.

In some cases, the limitation parameter is for forbidding the terminal to access the NB-IoT.If the limitation ginseng Number is for forbidding terminal to access NB-IoT, then terminal will determine time and/or the space model of limitation access according to limitation parameter It encloses, NB-IoT measurement is no longer carried out within the time of restriction and/or spatial dimension, the access request of NB-IoT will not be sent.

On the one hand, parameter limiting terminal is limited to forbid accessing NB-IoT in specific region；It is currently at the terminal of Idle state The NB-IoT of specific region will not be measured, the access request of NB-IoT is unlikely initiated according to measurement result.

On the other hand, it is directed to the multimode terminal that connected state is under other networks, it at least will not be based on to NB-IoT Network measure initiate to the access request of NB-IoT.

In some embodiments, NB-IoT will not even be carried out in the terminal with the connected state of other networks Network measure.Therefore in any case, once obtaining limitation parameter, the power consumption of terminal can at least be saved.Furthermore the program may be used also Signaling overheads can be reduced because reducing the transmission of terminal request, reduces network side and receive signaling number, net can be reduced The load of network side.

In other cases, the limitation parameter accesses the NB-IoT for limiting the terminal.The limitation parameter It can be used for limiting the access of NB-IoT.In this case, terminal is within the time and/or spatial dimension that limitation parameter limits NB-IoT or request access NB-IoT can be measured, but measures or the information such as the frequency accessed is requested to be restricted, relative to The frequency for measuring or accessing is allowed to be greatly reduced in the case of allowing terminal to access NB-IoT, at least can achieve section Save the purpose of power consumption.

Optionally, the cause value includes: region instruction parameter.The region indicates parameter, is used to indicate and forbids accessing Network area.

For example, the network area includes at least one of:

Public land mobile network (Public Land Mobility Network, PLMN)；

Tracking area (Tracking Area, TA) list (list)；It is mobile brought a large amount of in order to reduce the terminal area across TA Signaling overheads introduces the concept of TA list in 4G, i.e., when the described terminal moves in the TA being located in the same TA table, institute It states terminal and shields the request for sending tracing section updating to the network；

TA。

Optionally, the limitation parameter further includes at least one of:

Allow to request the maximum times of access NB-IoT in scheduled duration；

Allow the maximum times for requesting to access the same network area；

The frequency of request access NB-IoT；

The period of request access NB-IoT.

The introducing of above-mentioned parameter in the present embodiment reduces the power consumption and signaling overheads of terminal.

As shown in Fig. 2, being applied in terminal the present embodiment provides a kind of connection control method, comprising:

Step S201: the request of access NB-IoT is sent；

Step S202: the reason of reception is denied access value.

This method is applied in terminal, which can be various types of terminals, for example, internet-of-things terminal etc..

Firstly, terminal sends the request of access NB-IoT, this request is further referred to as access request.Secondly, terminal The reason of network returns to refusal access value can be received.Terminal can no longer be accessed NB-IoT based on the cause value or reduce access The frequency of NB-IoT, to save power consumption.

Optionally, the method also includes:

According to the cause value, limitation parameter is obtained.

For terminal after receiving cause value, terminal can obtain limitation parameter in the present embodiment.The limitation parameter can limit The access NB-IoT of terminal processed.For example, the limitation parameter can be used for that the terminal is forbidden to access the NB-IoT.For another example The limitation parameter can be used for limiting the terminal and access the NB-IoT.

The cause value can carry region instruction parameter, and the region instruction parameter is used to indicate the network for forbidding access Region.

For example, the network area includes at least one of: PLMN；TA list；TA.

Optionally, the limitation parameter further includes at least one of: allowing to request access NB-IoT's in scheduled duration Maximum times；Allow the maximum times for requesting to access the same network area；The frequency of request access NB-IoT；Request access The period of NB-IoT.What these limitation parameters can inquire automatically after receiving cause value for terminal.

As shown in figure 3, being applied in terminal the present embodiment provides a kind of connection control method, comprising:

Step S110: the access request sent to network；The access request, for requesting access NB-IoT；

Step S120: the reason of reception is denied access value；

Step S130: according to the cause value, the limitation parameter of access NB-IoT is determined.

The limitation parameter, for forbidding the terminal to access the NB-IoT.Alternatively, the limitation parameter is for limiting The terminal accesses the NB-IoT.

In the present embodiment, the terminal can send the access request that request is linked into NB-IoT to NB-IoT.Network connects After receiving the access request, judges the terminal and whether have permission and be linked into NB-IoT.Alternatively, whether network judges terminal Have permission the PLMN or TA for being linked into its request access.If terminal does not allow access to NB-IoT, corresponding PLMN or TA, institute Cause value can be sent to terminal by stating network, which can be carried by NAS#15 message.

For terminal after receiving the cause value, the terminal can determine the limitation ginseng according to the cause value Number.For example, terminal obtains the limitation parameter by parsing the cause value.For another example after receiving the cause value, The terminal local inquires the limitation parameter.

The limitation parameter is obtained according to the cause value is parsed, then carries the limitation parameter in the cause value Instruction information and/or the limitation parameter.If terminal, after receiving cause value, local search limits parameter, then can recognize It is the triggering information that parameter is limited described in terminal inquiry for the cause value.

In the present embodiment, the terminal can execute after determining the limitation parameter according to the limitation parameter Operation relevant to access NB-IoT.

The limitation parameter can be divided into two major classes:

The first kind forbids parameter, for forbidding terminal access NB-IoT, or forbids terminal access specific region NB-IoT；For example, terminal is forbidden to access NB-IoT in specific PLMN, NB- is accessed in specific TA list in TA or specific TA IoT etc.；Terminal can execute the quiescing of access NB-IoT based on parameter is forbidden.

Second class, restricted parameters are used to indicate the confined condition of the terminal access NB-IoT, and terminal can be based on limited The access of parameter execution NB-IoT.

In the present embodiment, if the terminal has determined the limitation parameter, would not as in the prior art, even if In the case where breaking off relations access, the still unconfined network measure for carrying out NB-IoT and request access again, therefore can reduce The data volume transmitted between signaling overheads and terminal and network side, greatly reduce terminal NB-IoT and non-NB-IoT it Between ping-pong reselection possibility.

In some embodiments, the terminal can be single-mode terminal, for example, only have access NB-IoT intellectual water meter, The single-mode terminals such as intelligent door and window.

In further embodiments, the terminal can be multimode terminal, for example, NB-IoT or non-can be linked into simultaneously The equipment of NB-IoT.If multimode terminal, which is apprised of, not to be allowed to access after NB-IoT, if without limiting parameter in the present embodiment It obtains, then may result in ping-pong reselection of the terminal that can establish connection with non-NB-IoT before NB-IoT and non-NB-IoT. If the terminal between NB-IoT and non-NB-IoT when being switched to hard handover, terminal once measures the signal quality of NB-IoT It is better than the signal quality of non-NB-IoT, then can disconnects automatically the connection of non-NB-IoT and request is linked into NB-IoT.But NB- IoT refuses terminal access, then terminal can return to non-NB-IoT again.In next cycle, terminal measures the signal of NB-IoT again Quality is better than non-NB-IoT, then terminal can repeat the operations such as last switching again, this not only results in terminal in NB-IoT and non- Ping-pong reselection between NB-IoT, while also resulting in terminal and non-NB-IoT can not keep stable connection, and make end The data that end can be sent originally by the connection between non-NB-IoT, the problem of can not sending or cannot slowly send.

Optionally, as shown in figure 4, the step S130 can include:

Step S131: according to the cause value, the region instruction parameter for forbidding the terminal access NB-IoT is determined；

Step S132: indicating parameter according to the region, determines the network area for forbidding the terminal access NB-IoT.

The step S130 includes at least two above step in the present embodiment, and one is determining region instruction parameter, Determine that present terminal is prohibited the network area of access.

For example, a network area can be a PLMN, a network area can also be one or more TA, or, one Region corresponding to TA etc. in a or multiple TA lists.

In the present embodiment, the region instruction parameter is one kind of aforementioned limitation parameter, and the limitation parameter can also wrap Include: other are prevented or restricted from the parameter of the terminal access NB-IoT to action time parameter etc., are not limited to the region instruction Parameter.The action time parameter may be used to indicate the action time section or effect duration of other limitations parameter (region instruction parameter) Deng.

Further, instruction parameter in the region includes: at least one in PLMN, TA list and TA.If described Region indicates that parameter is PLMN, then terminal is forbidden or the network area of limited attach is at least a PLMN.

The terminal be located at the same TA table in TA in move when, the terminal shield to the network send with Track area updates the request of (Tracking Area Update, TAU).In the present embodiment, TA list includes one or more TA Information.If terminal is moved between the TA in the TA list, terminal inner can execute TAU from guild, but not It can be not required to for network side it is to be understood that these information to needing to send TAU request operation to network, therefore can reduced The signaling number caused by across the TA movement of user that network side receives, reduces network load, substantially reduces network side and believe Enable the possibility of storm.

The region indicates parameter, is used to indicate PLMN, TA list for forbidding access to be or TA etc..

In some embodiments, the step S131 can include: when receiving the instruction for not allowing access to NB-IoT, Determine that forbidding the network area of access is PLMN；In this way, the network of network side is without change cause value, terminal is receiving When stating cause value, the PLMN that can directly think that terminal is currently located forbids it to be linked into NB-IoT.

In further embodiments, the step S131 can include: when receiving the reason for carrying the first instruction When value, determine that forbidding the network area of access is PLMN.

The step S131 may also include that when receiving the cause value for carrying the second instruction, determination is forbidden connecing The network area entered is the TA in corresponding TA list.

The step S131 may also include that determination is forbidden connecing when receiving the cause value for carrying third instruction The network area entered is TA.

In some embodiments, first instruction, the second instruction and third instruction correspond to the identical of the cause value The different bit values of bit.For example, being respectively represented using three kinds in four kinds of bit values of two bits in cause value described First instruction, the second instruction, third instruction.In some embodiments, the 4th kind of bit value of two bits, can be used for referring to Show and forbids terminal access LTE network etc..In this way, the number of bits that region instruction parameter uses is few, overhead bit is small, can use Reservation bit or remaining bits in existing cause value realize to have the characteristics that strong with prior art compatibility.

In further embodiments, first instruction, the second instruction and third instruction, can be respectively by different bits It is indicated.For example, being utilized respectively 1 bit indication forbids whether the network area of access is PLMN, TA list, two kinds of TA State.1 bit can be " 0 " and " 1 " two kinds of bit values, it is assumed that the corresponding network region for " 0 " instruction allows to access, it is assumed that Forbid accessing in corresponding network region for " 1 " instruction.

Therefore in the present embodiment, network issues there are many modes that first instruction is indicated to third, is not limited to State any one.

Optionally, in some embodiments, the cause value, which can be carried directly, forbids the letters such as the PLMN mark of access Breath can also be issued by dedicated signaling and forbid the information such as the PLMN mark of access, for example, passing through wireless heterogeneous networks (Radio Resource Control, RRC) transmitting signaling downwards PLMN mark etc. information.

Optionally, the step S130 can include:

According to the cause value, the limitation parameter that limitation accesses the NB-IoT is obtained, wherein the limitation parameter packet It includes: the network area for allowing the maximum times for requesting access NB-IoT in scheduled duration, allowing to request to access the same NB-IoT Maximum times, request access NB-IoT frequency, access NB-IoT period and measure NB-IoT period at least within One of.

In some embodiments, if after the terminal receives cause value, can by local search or from other Parameter is limited described in equipment query.In further embodiments, terminal can also receive the limit from other signalings of network side Parameter processed, alternatively, determining the limitation parameter by parsing the cause value.

If limitation parameter is the maximum times for allowing to request access NB-IoT in scheduled duration, terminal starts timer, Statistics sends request NB-IoT number of access in scheduled duration, if once reaching maximum times, can stop request access NB- IoT。

If limitation parameter is to allow to request to access the maximum times of the network area of the same NB-IoT, terminal can be counted The number of the request access NB-IoT of the same network area, once reaching maximum times, then the terminal stops requesting access should The NB-IoT of network area.

A specific example is provided below in conjunction with above-mentioned any technical solution:

Example 1:

(1) when the ownership place operator of NB-IoT terminal and diffuse in ground operator between without roaming cooperation when, diffuse in ground MME can directly refuse the access of the NB-IoT terminal, if ownership place MME does not restrict the terminal, ownership place Ownership contracting terminal server (Home Subscriber Server, HSS) can also refuse the roam-requests of the terminal.It overflows later #15 " No suitable cells in tracking area " cause value can be returned to by entering ground MME.

(2) when the ownership place operator of NB-IoT terminal and diffusing between ground operator has roaming to cooperate, but the NB- When the unsigned international roaming service of IoT terminal, diffusing in ground MME allows the access of the NB-IoT terminal, and ownership place HSS can refuse this The roam-requests of terminal.#15 " No suitable cells in tracking area " reason can be returned to by diffusing in ground MME later Value.

Including but not limited to both the above situation when MME returns to NAS#15 cause value to UE, but with honeycomb Internet of Things The development of business or exclusive feature due to NB-IoT business, it is also possible to which there are other situations can also return to NAS#15 cause value. So-called NAS#15 cause value, it may be possible to due to the unsigned roaming agreement of user, not roam cooperation or user between two operators Authenticated is illegal user, and the prioritization scheme of user's request is not supported, the above reason refusal user can return when accessing NAS#15 cause value, is specifically described to be worth for that reason, and provides the user with further movement instruction, so can also Subsidiary extended EMM cause adds a supplementary explanation, such as when by the 1st bit set in extended EMM cause Prioritization scheme for " 1 ", GC group connector request is not supported and is rejected.

If terminal be in non-NB-IoT access style (such as eMTC, GSM etc.) connected state, and network side be configured with it is non- NB-IoT to NB-IoT is based on measurement redirection function, and terminal supports non-NB-IoT to the NB-IoT based on measurement to redirect function Can, when meeting redirection measurement thresholding, terminal will be attempted and be redirected to NB-IoT.

Detailed analysis will be carried out to existing NB-IoT access mechanism below:

(1) it can frequently attempt to read when Idle state of the multimode terminal in non-NB-IoT access style (such as eMTC, GSM etc.) The system information of NB-IoT, but will not reside in NB-IoT, and terminal constantly measures NB-IoT access network and non-NB- The behavior of the signal strength of IoT access network will lead to power consumption of terminal increase；

(2) when multimode terminal is deployed and is based in the connected state and network of non-NB-IoT access style (such as eMTC, GSM etc.) The trial return mechanisms of the redirection of the NB-IoT of measurement, multimode terminal can between NB-IoT and non-NB-IoT ping-pong reselection, Cause the connected state business of non-NB-IoT access style (such as eMTC, GSM etc.) substantially unavailable；

When (tracking area is interior without suitable cell No suitable cells in tracking by NAS#15 for network Area) when the access of message refusal NB-IoT terminal, since existing honeycomb Internet of Things still has certain defect, thus lead to end Hold power consumption increase or UE on other wireless access types since ping-pong causes connected state business unavailable.We will below Detailed analysis is carried out to existing NB-IoT access mechanism:

(1) it can frequently attempt to read when Idle state of the multimode terminal in non-NB-IoT access style (such as eMTC, GSM etc.) NB-IoT system information, but will not reside in NB-IoT Internet of Things, and terminal constantly measures NB-IoT access network and non- The behavior of the signal strength of NB-IoT access network will lead to power consumption of terminal increase；

(2) when multimode terminal is deployed and is based in the connected state and network of non-NB-IoT access style (such as eMTC, GSM etc.) The trial return mechanisms of the redirection of the NB-IoT of measurement, multimode terminal can between NB-IoT and non-NB-IoT ping-pong reselection, Cause the connected state business of non-NB-IoT access style (such as eMTC, GSM etc.) substantially unavailable.

The motion of this example defines the extension instruction of the NAS#15 in NB-IoT and terminal receives the behavior after extension instruction On the one hand description can realize that there are a large amount of inactive signalings for network side caused by difference to avoid terminal, on the other hand can solve Certainly due to power consumption of terminal increase in current mechanism, UE is the problems such as connected state business is unavailable on other wireless access types.

This example is embodied in two o'clock: on the one hand defining extension instruction, another party for the NAS#15 cause value of NB-IoT Behavior in face of terminal is further standardized.

Fig. 9 and Figure 10 show a kind of letter of the Extended EMM cause message of NAS#15 cause value expansion value Meta structure, the cell structure can include: 8 hytes (octet1), totally 8 bits.1st bit indication E-UTRAN allows Whether, it is " 1 " Shi Buyun if the bit value for specifically illustrating the bit in fig. 8 is that " 0 " instruction allows terminal to access LTE net Perhaps terminal accesses LTE network.2nd bit is EPS optimization instruction, and instruction is that have the optimization for carrying out EPS, for example, control plane user, Internet-of-things terminal may transmit a large amount of small data packets (for example, data packet that data packet length is less than preset length), or frequency The burst packet of numerous transmission.When if desired transmitting these data, require first to build using the control plane signaling in control plane path Vertical data surface connection, then the connection of the data surface based on foundation send these data packets, and it is more on the one hand to will lead to control plane signaling, separately On the one hand it will lead to that data transmission delay is big, then can directly transmit these small data packets of data surface using control plane path Or the particular data packet frequently sent, this is a kind of control plane optimization.As shown in figure 8, EPS optimization instruction can be used to indicate It is the control plane optimization for supporting UE request.The 2nd bit is that " 0 " indicates to optimize instruction without EPS in fig. 8, indicates to refuse if " 1 " The reason of user accesses is because network side does not support the EPS optimization of request.3rd bit and the 4th bit are idle bit at present, It can at least be used to refer to region instruction parameter in this example, for example, PLMN, TA list of instruction refusal access or TA etc.. In Fig. 9, NAS#15 message further include extension EMM reason cell identifier (Information Element Identifier, IEI), for the 5th to the 8th bit in the octet1 of occupancy.

It is described as follows:

(1) the extension instruction of the NAS#15 of network

1. the extension indication scheme of the NAS#15 based on PLMN

The program need to only be transformed MME, while terminal being needed to support.(ATTACH REJEST) is broken off relations in attachment to disappear For NAS#15 message definition EMM extension instruction in breath, it is worth for " being forbidden to use NB-IoT in the PLMN " access capability.

2. the extension indication scheme of the NAS#15 based on TA list

The program needs all to be transformed NB-IoT and other access style networks (such as eMTC, GSM etc.), needs simultaneously Terminal is supported.EMM extension instruction is defined in ATTACH REJEST message, instruction limitation " TA list in part in the PLMN " connects Enter, " the TA list of limitation " cell can be carried and is sent to UE.

3. the extension indication scheme of the NAS#15 based on TA

The program needs all to be transformed NB-IoT and other access style networks (such as eMTC, GSM etc.), needs simultaneously Terminal is supported.EMM extension instruction is defined in ATTACH REJEST message, instruction limitation " part TA in the PLMN " access can With carrying " TA of limitation " cell and it is sent to UE.

Solution (" the limiting terminal weight of terminal being set forth above is combined for the existing issue in current NB-IoT The number attempted again " and " period of limiting terminal repeated attempt " are all made of default value), following detailed analysis can be carried out:

(1) after multimode terminal, which attempts access NB-IoT, to be refused, the sky of non-NB-IoT access style (such as eMTC, GSM etc.) When not busy state, the system information for reading NB-IoT can be frequently attempted, but will not be resided in NB-IoT Internet of Things, and terminal is continuous The behavior of the signal strength of measurement NB-IoT access network and non-NB-IoT access network causes power consumption of terminal to increase.

(2) when multimode terminal deploys return in the connected state and network of non-NB-IoT access style (such as eMTC, GSM etc.) The redirection of NB-IoT attempts mechanism, multimode terminal can between NB-IoT and non-NB-IoT ping-pong reselection, lead to non-NB-IoT The connected state business of access style is substantially unavailable.

(4) the specific implementation citing of solution

Based on the extension indication scheme of above-mentioned three kinds of NAS#15, it is for reference to provide several concrete implementation modes.

1. implementation one: original Extended EMM cause message is only attempted access LTE network in terminal and is refused When use, have no the related definition for attempting access NB-IoT when being refused.In this implementation, if terminal attempts access NB- IoT is rejected, and forbidden is PLMN, then can be multiplexed existing Extended EMM cause completely in NB-IoT. In other words, it is indicated in the PLMN not if terminal is attempted to return to E-UTRAN not allowed when access LTE network is refused Allow to access LTE network, indicate if terminal is attempted to return to E-UTRAN not allowed when access NB-IoT is refused at this Do not allow to access NB-IoT in PLMN, the same field has different explanations under different access conditions.

2. implementation two: original Extended EMM cause cell does not make definition to bit 3 and bit 4, It will be extended definition to this two in this implementation, be described in detail as follows:

In short, the motion of this example will be directed to the deficiency of prior art, relevant solution is proposed, for example, new fixed The extension of NAS#15 of the adopted NB-IoT based on PLMN indicates that Idle state multimode terminal receives the NAS#15 with extension instruction After message, the signal strength of NB-IoT access network is no longer measured in the PLMN.

The new extension instruction for defining NAS#15 of the NB-IoT based on PLMN, connected state multimode terminal receive this with extension It after the NAS#15 message of instruction, is no longer attempt to access NB-IoT again in the PLMN, and attempts from other wireless access types Access.

The new extension instruction for defining NAS#15 of the NB-IoT based on TA or TA list, Idle state multimode terminal receive the band After the NAS#15 message for having extension to indicate, NB-IoT access network and non-NB-IoT are no longer measured in TA the or TA list collection Access the signal strength of network.

The new extension instruction for defining NAS#15 of the NB-IoT based on TA or TA list, connected state multimode terminal receive the band Have extension indicate NAS#15 message after, be no longer attempt to access NB-IoT again in TA the or TA list collection, and attempt from The access of other wireless access types.

Terminal behavior is standardized, terminal receive extension instruction after can strict implement core net instruction, at this PLMN, certain TA or TA lists are no longer attempt to access NB-IoT signal strength.

In addition, the motion of this example has carried out further specification, and the expansion to three kinds of NAS#15 are newly defined to terminal behavior Exhibition instruction, the first is based on PLMN, and second is based on TA list, the third is based on TA；When terminal receives this After three kinds of reasons all relevant movement need to be executed according to the requirement in this programme to terminal.Motion very good solution multimode Terminal increases in the Idle state power consumption of non-NB-IoT access style (such as eMTC, GSM etc.) and multimode terminal connected state can be in NB- Ping-pong reselection between IoT and non-NB-IoT leads to the not available problem of connected state business.

Example 2:

This example provides a kind of connection control method, equally can solve the technical problem in example 1.

It needs further to standardize terminal behavior, defines " number of limiting terminal repeated attempt " and " limitation is eventually Hold the period of repeated attempt ".

The meaning of " number of limiting terminal repeated attempt " is that the terminal is allowed to permit in the PLMN or certain TA or TA lists Perhaps connected state attempts the number of repetition of access or detection NB-IoT signal strength.Value default is set as " 0 ", i.e., if the terminal exists The PLMN or certain TA or TA lists are rejected, and terminal would not be accessed in corresponding region in the extension of return instruction Attempt or detect NB-IoT signal strength.

The meaning in " period of limiting terminal repeated attempt " is that the terminal is allowed to permit in the PLMN or certain TA or TA lists Perhaps connected state attempts the period of access or detection NB-IoT signal strength.Value default is set to infinity, i.e., if the terminal It is rejected and will not be attempted again in the PLMN or certain TA or TA lists.

" number of limiting terminal repeated attempt " is increased and after " period of limiting terminal repeated attempt ", when the item of network Part change (signing of such as terminal become allow access NB-IoT) when, it is convenient that terminal is configured and accesses NB- again IoT。
