Referring to fig. 2, the embodiment of the present invention provides a kind of network registering method, as shown in Figure 2, comprising the following steps:

201, terminal initiates the first tracing section updating request message；

202, terminal receives the refuse information for the first tracing section updating request message that the first core net function is sent；

203, terminal sends the second tracing section updating request message or login request message to the first core net function；

204, terminal receives the received message that the first core net function is sent, and the received message includes described first Core net function is the first temporary identifier of the terminal distribution.

In the embodiment of the present invention, above-mentioned first tracing section updating request message can refer to wireless heterogeneous networks (RRC, Radio Resource Control) message, and above-mentioned first tracing section updating request message can be periodical TAU The request message of (period TAU), such as: terminal enters non-permitted region (non-allowed area), and cannot initiate The request message for the periodical TAU that positive mobile TAU (mobility TAU) is initiated afterwards；Or it is sent out after entering MO only mode The request message of the periodical TAU risen.

Wherein, above-mentioned MO only mode refer to terminal enter can only active initiating business request (calling service), Bu Nengjie Receive the mode of network paging.Wherein, when endpoint to register is to network, decided whether to enable the mode by network, if enabling the mode, Then terminal is after disconnecting the connection with network, into special idle mode.Under this idle mode, terminal is without monitoring net Network paging, therefore called service can not be received.In order to allow network to save the context of the terminal, the terminal under the mode is special Need periodically to initiate periodicity TAU process under Idle state, which is equivalent to holding activation (keep alive) process, mesh Be to let the network know that the terminal still in net, rather than because of private attachment removal.

Above-mentioned Non-allowed area, which can be network, may will limit the geographic area that certain terminals obtain business, because This network, which can issue, allows region (allowed area) to terminal, and terminal can normally obtain network in allowed area Service, and except allowed area, i.e. non-allowed area, terminal cannot obtain proper network service, i.e. terminal It is unable to initiating business request and session establishment request.In order to allow organic will be updated of network to distribute to the allowed area of terminal, Terminal still allows for initiating periodical TAU after entering non-allowed area.

In addition, step 201, which can be to access net function, sends the first tracing section updating request message, by the access net function Can by the first tracking area request forwarding perhaps be routed to the first core net function or by access net function by the first tracking area more Non-Access Stratum (NAS, Non-Access-Stratum) protocol Data Unit (PDU, Protocol Data in new request message Unit) it is sent to above-mentioned first core net function.Certainly, in some scenes, it is also possible to direct to the first core net function Send above-mentioned first tracing section updating request message.

Above-mentioned refuse information can indicate that above-mentioned first tracing section updating request message is rejected, such as: by the first core Net function refusal.In addition, above-mentioned refuse information can be RRC refuse information.

Terminal is after receiving above-mentioned refuse information, so that it may send above-mentioned second tracking area more to the first core net function New request message or login request message, to request the first core net function for above-mentioned first temporary identifier of the terminal distribution (temporary ID).Wherein, above-mentioned second tracing section updating request message can be normal mobile TAU (mobility TAU).First core net function receives above-mentioned second tracing section updating request message or login request message can be for the end The first temporary identifier of end distribution, and return to above-mentioned received message.Wherein, above-mentioned received message can be above-mentioned second tracking area more The new received message of request message or the received message of login request message.

It is also available after can realizing that the tracing section updating request message of terminal initiation is rejected through the above steps It is the temporary identifier of its distribution to core net function, to complete registered network.

Wherein, the above-mentioned signing that not can be the not no terminal of the first core net in the first core net function register Perhaps the first core net function does not have the temporary identifier of terminal or the first core net function is not this for information and context Terminal distribution crosses mark.In the embodiment, if terminal may be implemented not in the first core net function register, first Core net function refuses the first tracing section updating request message, to pass through the second tracing section updating request message as the terminal distribution Temporary identifier, to complete registered network.

In addition, if above-mentioned first tracking area request message be by access net function send, then, above-mentioned first core Net function can be to access the judgement of net function to cannot connect to the second core net function of the second temporary identifier instruction In the case of the core net function that selects.Or above-mentioned first tracing section updating request message may include network example selection auxiliary Information (NSSAI, network slice selection assistance information), if above-mentioned first tracking area is asked Ask message be by access net function sends, then, above-mentioned first core net function can for the access net function use institute State the core net function of network example selection auxiliary information selection.

Optionally, the refuse information further includes the first cause value:

Above-mentioned first cause value can need to send the second tracing section updating request message or registration request with instruction terminal Message, and the cause value can be core net function and terminal consults in advance or terminal is pre-configured with can identify this Cause value.After i.e. terminal gets above-mentioned cause value, so that it may which determination needs to initiate above-mentioned second tracing section updating request message Or login request message completes registered network to receive above-mentioned first temporary identifier.It should be noted that the present invention is real Apply do not include in example above-mentioned first cause value be also possible to realize, i.e., terminal can be pre-configured receive above-mentioned refuse information after Above-mentioned second tracing section updating request message or login request message can be sent.

Optionally, above-mentioned received message further includes the second cause value, second cause value be used to indicate no longer initiate it is non- Periodical tracing section updating request message.

In the embodiment, after terminal receives above-mentioned second cause value, so that it may no longer initiate aperiodic tracking area Update request message, certainly, here do not imply that permanent not initiating updating of tracking area request message no longer.It here is no longer may be used To be interpreted as not needing initiating updating of tracking area request message within subsequent a period of time, for example, being not required within a TAU period Want initiating updating of tracking area request message.Tracking area update request message is repeatedly initiated by above-mentioned third cause value, with drop The expense of low Internet resources and system signaling.

In addition, third cause value here can be sent out after the first core net function determines the terminal that terminal is preset kind It send, the terminal of preset kind includes the terminal for entering MO only mode or entering non-permitted region.May further be into Enter MO only mode, or enters the terminal in non-permitted region and the terminal of normal mobility TAU cannot be initiated.

Optionally, above-mentioned terminal initiates the first tracing section updating request message, comprising:

In the embodiment, the first tracing section updating request message can be the request message of periodical TAU, such as: eventually End enters MO only mode, perhaps enters the terminal in non-permitted region or enters the terminal in non-permitted region and cannot send out When playing normal mobility TAU, the request message of the periodical TAU of initiation.And above-mentioned second tracing section updating request message It then can be non-periodic sending, such as: just playing the request message of normal mobility TAU.

Optionally, above-mentioned terminal includes:

Step 2. access net function receive RRC request message after, if cannot forward the message to the second temporary identifier (UE's Temporary ID) indicated by the second core net function, such as mobile management function to ps domain can then select the by the prior art One core net function, such as mobile management function to ps domain, and the first core net function is sent by NG2 interface message by the NAS PDU Can, RRC request message is either routed or is forwarded to the first core net function.

Step 3, the first core net function receive the RRC information of NAS PDU or periodicity TAU request, and refusal TAU is asked It asks, can refuse to request with above-mentioned second cause value here.

After step 4, terminal receive refuse information, mobility TAU request is re-initiated according to the second cause value, i.e., the Two tracing section updating request messages.

After step 5, the first core net function receive mobility TAU Request, obtained eventually from the second core net function The signing information and UE Context at end, then determine that the terminal is MO according to the signing information of terminal or UE Context Only mode enters non-allowed area, there is no need to distribute TAI list for UE, and only distributes new UE temporary ID。

Another example is: as shown in figure 4, including the following steps:

Step 1, after terminal enters non-allowed area and cannot initiate normal mobility TAU, or UE enters after MO only mode, and UE needs to initiate periodicity TAU, and UE is needed in the RRC for carrying periodicity TAU request at this time NSSAI is carried in message.

After step 2, access net function receive RRC request message, NSSAI is obtained from message.Access net function according to NSSAI selects the first core net function, such as CCNF, and sends selected first core for the NAS PDU of RRC request message Heart net function.

It should be noted that can be combined with each other realization in the embodiment of above-mentioned introduction in the embodiment of the present invention, it can also To be implemented separately, this embodiment of the present invention is not construed as limiting.
