The network architecture and business scenario of the embodiment of the present application description are to more clearly illustrate that the application is implemented The technical solution of example, does not constitute the restriction for technical solution provided by the embodiments of the present application, those of ordinary skill in the art It is found that technical solution provided by the embodiments of the present application is for similar with the differentiation of the network architecture and the appearance of new business scene The technical issues of, it is equally applicable.

As shown in Figure 1, disposing architecture diagram for local network.Terminal (such as passes through Radio Access Network by accessing net (radio access network, RAN) equipment) it is linked into core net.Core net includes that control plane network element and user's veil are first, Wherein, control plane network element is for example including session management network element, mobile management network element etc..Terminal can be by accessing net, with nothing The mode of line access accesses user's veil member, and by user's veil member access data network (data network, DN) Using data.

Currently, the position in the network architecture close to access net deploys local network in order to reduce the delay of access, this Ground network is also referred to as LADN.LADN refer to covering specific localized areas data network, such as cover enterprise campus, campus, airport, The data network in the places such as railway station, shopping mall or gymnasium.As shown in Figure 1, being disposed close to the position of access net LADN correspondingly increases local user's veil member for accessing LADN.Therefore, terminal can be by accessing net, with nothing The mode of line access accesses local user's veil member, so as to which the corresponding LADN of local user's veil member is directly accessed, It does not need around external data network, it is possible to reduce the time delay using data in access data network, while can also drop The transmission bandwidth of low backbone network.

In concrete application, such as live broadcast can be provided in gymnasium；Garden communication is provided in campus, accesses campus Interior education resource；Industrial control communication is provided in enterprise campus；The preferential push of local shopping is provided in market and real time position is led Boat etc..

LADN DNN can be used to identify in one LADN, and LADN DNN can be understood as the identification information of a LADN, For one LADN of unique identification.

The service range of LADN is made of the cell of its service or RAN equipment, such as the service range of LADN can be used Cell list (cell list) indicates, for example the service range of LADN is { cell1, cell2, cell3 }, then it represents that the LADN Service can be provided for user access in cell1, cell2, cell3 and the LADN that contracted.

For another example, the service range of LADN can also use tracking zone list (track area list, TA list) Indicate, each TA includes one or more cells, for example the service range of LADN is { TA1, TA2 }, and TA1 be cell1, Cell2 }, TA2 is { cell4, cell6 }, then it represents that the LADN can be accessed in cell1, cell2, cell4, cell6 And the user for the LADN that contracted provides service.

Below with reference to the network architecture and system architecture shown in Fig. 2 of LADN application scenarios shown in FIG. 1, the application is introduced A kind of conversation processing method provided, this method can be used for solving the problems, such as waste of resource present in background technique.

As shown in figure 3, being conversation processing method provided by the present application, the AMF in this method can be movement shown in Fig. 2 Property managed network element, the SMF in this method can be session management network element shown in Fig. 2, and the terminal in this method can be Fig. 2 institute The terminal shown.Method includes the following steps:

Step 301, AMF receives request message, and the request message provides conversational services for requesting for terminal.

The conversational services, such as can be and establish session, active session or switching session etc..

Step 302, AMF is if it is determined that terminal except the service range of LADN, then refuses the conversational services.

Whether the above method first determines whether terminal in LADN after AMF receives the request for providing conversational services for terminal Service range except.If it is determined that terminal except the service range of LADN, then directly refuses the conversational services of the terminal, without It is first to receive the conversational services to discharge again, to reduce the resource occupation of invalid conversational services, helps to reduce resource wave Take.

Below with reference to different scenes, the different implementations of above-mentioned conversation processing method are introduced.

Application scenarios one, terminal request establishes session

For example, terminal sends request message to RAN equipment, which includes DNN, and the request message is for asking rooting Session is established according to the DNN, it is understood that is that the request message is used to request to establish the session of the DNN.

Then the request message is sent to AMF by RAN equipment, while the location information of the terminal is also sent to the AMF.

It should be noted that terminal can initiate register flow path before session is established in request, and in register flow path, The available signing information to DNN of terminal, by taking specific example shown in Fig. 4 as an example, what terminal was got in register flow path The signing information of DNN includes: { LADN DNN1 }.Wherein LADN DNN1 is the mark of LADN1.

Wherein, the signing information of DNN is referred to as the corresponding signing information of DNN, and the two has the same meaning, after Continuous no longer independent explanation.

Further, optionally, in the register flow path of terminal, AMF can also be obtained from UDM and be stored the terminal The signing information of DNN, i.e. { LADN DNN1 }.

Further, can also record whether a DNN is LADN DNN on UDM, at this point, registration of the AMF in terminal It further include instruction information from the signing information of the DNN for the terminal that UDM is obtained and is stored in process, which is used for Indicate whether the DNN is LADN DNN, for example, being directed to above-mentioned example, the then DNN for the terminal that AMF and terminal are got from UDM Signing information are as follows: { LADN DNN1 is LADN DNN }.

In the concrete realization, as a kind of implementation, which can be a flag.For example, flag is True (such as can be indicated with " 1 ") indicates that the DNN is LADN DNN, and flag is false (such as can be indicated with " 0 "), table Showing the DNN not is LADN DNN.

Further, if having LADN in the service range of an AMF, in the service range that the AMF is also configured on the AMF LADN information, the information of the LADN includes the service range of the mark of the LADN (being indicated with LADN DNN) and the LADN, Wherein, the service range of LADN is referred to as the corresponding service range of LADN DNN.

By taking Fig. 4 as an example, for example, have LADN1 and LADN2 in the service range of the AMF1 in Nanjing, wherein LADN1 is identified as LADN DNN1, LADN1 service range be cell1-cell3, the service range for being identified as LADN DNN2, LADN2 of LADN2 For cell3-cell6.The information of the LADN then configured on AMF1 includes: { LADN DNN1, cell1-cell3 }, { LADN DNN2, cell3-cell6 }.Also, the DNN that service range information is configured on AMF is LADN, and other DNN are not done Configuration, therefore, for configuring the DNN on AMF, it may not be necessary to determine whether the DNN is LADN by instruction information.

To sum up, in the examples described above, in the register flow path of terminal, the signing information that terminal gets DNN includes: { LADN DNN1 is LADN DNN }.Assuming that the AMF in the register flow path of terminal is above-mentioned AMF1, then optionally, the AMF1 The signing information of the DNN of the available terminal arrived includes { LADN DNN1 is LADN DNN }.Further, on the AMF1 It is also configured with the information of LADN, comprising: { LADN DNN1, cell1-cell3 }, { LADN DNN2, cell3-cell6 }.

It is configured below with reference to above-mentioned example, and according on the DNN and AMF carried in the current location of terminal, request message LADN information, be illustrated.It should be noted that be illustrated as an example with above-mentioned example here, It does not constitute to specific restriction of the invention.

Step A, AMF judge whether the DNN carried in request message is LADN DNN.If it is not, then according to the prior art Process executes, if so, thening follow the steps B.

As a kind of implementation, AMF, can be according to before in the note of terminal after getting the DNN in request message The signing information of the DNN of the terminal got in volume process, to judge whether the DNN is LADN DNN.

As another implementation, if AMF in the register flow path of terminal, does not obtain the signing of the DNN of the terminal Information, then the DNN obtained from request message can be sent to UDM by AMF, and request UDM is inquired and returned to the signing letter of the DNN Breath, include in the signing information of the DNN DNN whether the instruction information for being LADN DNN, then AMF is according to the instruction information, Determine whether DNN is LADN DNN.

As another implementation, AMF can also be according to the information of the LADN configured on AMF, to judge request message In DNN whether be LADN DNN.For example, if in the information of the LADN configured on AMF including the DNN in the request message, Show that the DNN is LADN DNN, if the information of the LADN configured on AMF does not include the DNN in the request message, a kind of possibility Be: the DNN in the request message is not LADN DNN, alternatively possible to be: the DNN in the request message is LADN DNN, but It is not configured on the AMF, i.e., the service range of the AMF does not include the LADN that the LADN DNN is indicated.

By any of the above-described mode, AMF may determine that whether the DNN carried in request message is LADN DNN.

In this case, it is LADN DNN, data network indicated by the DNN that AMF, which determines the DNN carried in request message not, Network DN does not have the limitation of specific service range, and therefore, AMF can establish the session of the DNN with direct request SMF.

The specific implementation process of the situation is the prior art, and which is not described herein again.

Step B, the DNN are LADN DNN, and AMF judges whether terminal has contracted the LADN DNN.If terminal is not contracted The LADN DNN, then refusal establishes session, if the terminal unit contractual LADN DNN, thens follow the steps C.

AMF judges that whether the contracted mode of the LADN DNN of the terminal may is that

In one implementation, if AMF has got the label of the DNN of the terminal in the register flow path of terminal from UDM About information, then AMF can be by the LADN DNN that carries in request message, in the context that locally search the terminal, if can be with The corresponding signing information of LADN DNN is found, then shows that the terminal unit contractual LADN DNN shows if not finding The unsigned LADN DNN of the terminal.

In another implementation, if AMF in the register flow path of terminal, does not obtain the signing of the DNN of the terminal Information, then the LADN DNN obtained from request message can be sent to UDM by AMF, and request UDM is inquired and returned to the LADN The signing information of DNN, then AMF can judge whether the terminal has contracted the LADN according to the signing information of the LADN DNN DNN。

It should be noted that being first to judge whether the DNN carried in request message is LADN in above-mentioned steps A and step B DNN, then judge whether terminal has contracted the DNN.In practical application, it can also be first judge whether terminal has contracted the DNN, then Judge whether the DNN is LADN DNN.Alternatively, can also be that above-mentioned two deterministic process is performed simultaneously, i.e., in one step Above-mentioned two judgement is completed, for example, if AMF has got the signing information of the DNN of the terminal in the register flow path of terminal, it should In the signing information of DNN include the DNN whether the instruction information for being LADN DNN, then AMF can judge the request of terminal simultaneously Whether message DNN is LADN DNN, and judges whether terminal has contracted the DNN.

For example, that carry in the request message that terminal is sent to AMF1 is LADN DNN2 with reference to Fig. 4, i.e. request is established The session (or establishing session according to LADN DNN2 for request) of LADN DNN2, then AMF1 may determine that the terminal is unsigned The LADN DNN2, and refuse to establish the session of LADN DNN2.

And, it should be noted that in another implementation, the judgement movement of above-mentioned steps B can not also be executed.Than Such as, in one implementation, if carrying DNN in the request message that terminal is sent, default the terminal unit contractual DNN, If i.e. terminal carries DNN in request message, show the terminal unit contractual DNN.Therefore, in this implementation, then Terminal in example shown in Fig. 4 carries LADN DNN1, at this point, AMF1 when session is established in request in the request message of transmission Do not need to judge whether the terminal has contracted LADN DNN1.

Step C, AMF judge that the information that the LADN whether is configured on AMF is refused if the information of the LADN is not configured Session is established, if being configured with the information of the LADN, thens follow the steps D.

The information of the LADN in the service range of the AMF is pre-configured on AMF, the Nanjing according to preceding description, in Fig. 4 AMF1 on the information of LADN that configures are as follows: { LADN DNN1, cell1-cell3 }, { LADN DNN2, cell3-cell6 }.

Further, the information of the LADN configured on the AMF2 in Xi'an are as follows: { LADN DNN3, cell30-cell35 }, { LADN DNN4, cell36-cell38 }.

For example, in a kind of scene, it is assumed that the user for carrying terminal shown in Fig. 4 goes on business to Xi'an, and then user is logical The terminal to be crossed to initiate to establish the request of the session of LADN DNN1 to the AMF2 in Xi'an, i.e. terminal sends request message to AMF2, Middle carrying LADN DNN1.

Firstly, the AMF2 can in such a way that A through the above steps and step B are mentioned, judge the LADN DNN2 whether be LADN DNN, and judge whether the terminal has contracted the LADN DNN2, however, it is determined that the LADN DNN2 is LADN DNN, and should The terminal unit contractual LADN DNN2 then further judges signing information that the LADN DNN2 whether is configured on AMF2.

In this example, due on AMF2 and the information of the LADN DNN2 being not configured, show in the service range of AMF2 simultaneously It does not include LADN2, the requested session for establishing LADN DNN2 of terminal is not allowed to, therefore AMF2 refuses the foundation The session of LADN DNN2.

Whether step D, the position where AMF judges terminal are located at except the service range of LADN, if so, refusal is established Session, if it is not, then receiving to establish session.

According to the judgement of abovementioned steps A- step C, it has been determined that the DNN carried in the request message of terminal is LADN DNN, the terminal unit contractual LADN DNN, and also provided the information of the LADN on AMF, then AMF further judges that terminal is worked as again Whether the position at preceding place is located at except the service range of the requested LADN of terminal.

Wherein, the position where terminal can be sent to AMF by the access device (such as RAN equipment) that terminal accesses, i.e., should Request message from access device to AMF forwarding terminal while, the location information of the terminal is also sent to AMF, the location information In include the position that is currently located of the terminal, the subdistrict position where terminal can be used for example indicates.

With reference to Fig. 4, the example under one kind scene is provided.The RAN equipment that terminal is accessed by terminal is asked to AMF1 transmission Message is sought, which includes LADN DNN1, and the location information of terminal is also sent to AMF1 by the RAN equipment.

In a kind of example, if terminal is currently located at cel l4, AMF is first depending on abovementioned steps A and step B, determines The LADN DNN1 is LADN DNN, the terminal unit contractual LADN DNN1, and the letter of the LADN DNN1 is configured on AMF1 Breath, but AMF1 judgement learns that position cell4 that the terminal is currently located is the i.e. clothes of LADN1 except the service range of LADN1 Business range is cell1-cell3, but terminal is currently in cell4, and therefore, what AMF1 still can refuse the terminal establishes LADN The session request of DNN1, i.e. refusal establish session.

In another example, if terminal is currently located at cell1, AMF is first depending on abovementioned steps A and step B, and determining should LADN DNN1 is LADN DNN, the terminal unit contractual LADN DNN1, and the information of the LADN DNN1 is configured on AMF1, Further, AMF1 judgement learns within the service range of LADN1, i.e., the position cell1 that the terminal is currently located is The service range of LADN1 is cell1-cell3, and terminal is currently within cell1, the service range in LADN1, therefore, AMF1 receives the session request for establishing LADN DNN1 of the terminal, that is, receives to establish session.

It should be noted that step B can also be first carried out as a kind of implementation, step C is then executed, in step C In, if AMF determines the information for being configured with the DNN on AMF, show that the DNN is LADN DNN, then proceed to execute step D, If AMF determines the information that the DNN is not configured on AMF, step A is also needed to be implemented after step c, if determining according to step A Then the terminal unit contractual DNN executes step D if determine the unsigned DNN of terminal according to step A and refuses the session.

As another implementation, it is somebody's turn to do if terminal only can just be carried when having contracted DNN in request message Above-mentioned steps C- step D then can also be performed in DNN.

Further, optionally, if AMF determines refusal session, that is, refuse the session for establishing DNN, then AMF is also sent out to terminal The first instruction information is sent, which is used to indicate refusal and establishes session, that is, establishes the DNN's carried in request message Session.

Further, optionally, if AMF, which is determined, receives session, that is, receive the session for establishing DNN, then AMF can ask this It asks message to be forwarded to SMF, continues subsequent session establishment process, to complete the foundation of the session of the DNN.

In the scene, it is following several to determine that situation of the terminal except the service range of LADN has:

1) information of the DNN carried in request message, is not configured on AMF, shows that the AMF cannot provide foundation for the terminal The conversational services of LADN.

Wherein, the information that the DNN carried in request message is not configured on AMF specifically includes: the DNN is not LADN DNN； Alternatively, the DNN is LADN DNN, but the information of the LADN DNN is not configured on AMF.

2), the DNN carried in request message is LADN DNN, the information of the LADN DNN is configured on AMF, but terminal is worked as It is preceding not in the service range of the LADN.

In this scenario, after AMF receives the request for establishing session of terminal, first determine whether terminal whether LADN's Except service range.If it is determined that terminal except the service range of LADN, then directly refuses the request for establishing session of the terminal, Rather than first establish the session and discharge again, to reduce the resource occupation for establishing invalid session, help to reduce resource wave Take.

Application scenarios two, terminal requests activation session

In the application scenarios, terminal passes through RAN equipment, the one or more meetings carried in the request message sent to AMF The mark of words, for example a list can be sent to AMF, it include the mark of one or more sessions, these sessions in the list For session to be activated.The request message activates these sessions for requesting.

AMF obtains the mark of session therein after receiving request message, and determines the corresponding DNN of these sessions.It needs It is noted that the corresponding DNN of these sessions can be the same DNN, it is also possible to different DNN.

For each session, AMF requires to judge whether to activate the session.In the case of the DNN is LADN, if AMF determines the terminal except the service range of the corresponding LADN of the session, then refuses to activate the session, if AMF determines the end The session is then activated within the service range of the corresponding LADN of the session in end.

Specifically, AMF determines that terminal within the service range of the corresponding DNN of session, needs to meet the following conditions simultaneously: The session corresponding DNN be LADN DNN, the information that the LADN is configured on the terminal unit contractual LADN DNN, AMF and The terminal is currently located in the service range of the LADN.

AMF judges whether the concrete methods of realizing of active session, judges whether to establish with AMF in above-mentioned application scenarios one and ask The method of the session of the DNN asked is similar, can refer to the associated description of the step A- step D in above-mentioned application scenarios one, here not It repeats again.

It should be noted that if AMF determines that refusal activates some session, then AMF does not send the mark of the session to SMF.

It is illustrated below with reference to a specific example.For example, terminal send request message include session 1 mark, The mark of the mark of session 2, the mark of session 3 and session 4, the request message is for requesting the activation session 1, session 2, session 3 and session 4.

The corresponding DNN of session 1 is LADN DNN1, which is LADN DNN1, and the session 3 is corresponding DNN is LADN DNN1, which is LADN DNN2, and session 1, session 3 and the corresponding SMF of session 4 are SMF1, the corresponding SMF of session 2 are SMF2.

With reference to Fig. 4, if terminal initiates the request message of the active session in the cell1 in the service range of LADN1, The method that AMF1 uses aforementioned scene one, determines active session 1, session 2 and session 3, and not active session 4.

In turn, the mark of the mark of session 1 and session 3 can be sent to SMF1 by AMF1, activate the session 1 for requesting With session 3, and the mark of session 2 is sent to SMF2, activates the session 2 for requesting.For session 4, due to determining not The session is activated, therefore does not send the mark of the session 4 to the corresponding SMF1 of the session 4.

Wherein, AMF1 can send the mark of session to SMF1 or SMF2 in the following manner:

In one implementation, AMF only handles the mark of a session every time.For example, the execution operation of AMF1 is successively Are as follows:

The mark of session 1 is sent to SMF1 by AMF1；

The mark of session 2 is sent to SMF2 by AMF1；

The mark of session 3 is sent to SMF1 by AMF1.

In another implementation, the mark of the corresponding multiple sessions of AMF same SMF per treatment.For example, AMF1 Execution operation successively are as follows:

The mark of the mark of session 1 and session 3 is sent to SMF1 by AMF1；

The mark of session 2 is sent to SMF2 by AMF1.

By the above method, realizing will only determine that the mark for needing the session activated is sent to corresponding SMF.

It further, optionally, can also be to if AMF, which is determined, does not activate one or more sessions in request message Terminal sends second indication information, which is used to indicate refusal and activates the session.

For example, being directed to above-mentioned example, AMF1 can also send second indication information to terminal, wrap in the second indication information The mark for including session 4 is used to indicate refusal and activates the session 4.

In this scenario, after AMF receives the request of the active session of terminal, first determine whether terminal whether LADN's Except service range.If it is determined that terminal except the service range of LADN, then directly refuses the request of the active session of the terminal, Rather than the session is first activated to discharge again, to reduce the resource occupation for activating invalid session, help to reduce resource wave Take.

Application scenarios three, access device (such as RAN equipment) the request switching session that terminal is currently accessed

In the application scenarios, the request of access device that terminal is currently accessed is that terminal switches session, and the access device is to AMF Request message is sent, which includes the mark of one or more sessions, for example can send a list to AMF, should It include the mark of one or more sessions in list, these sessions are to be switched session.The request message is for requesting switching These sessions.

For each session, AMF requires to judge whether to switch the session.In the case of the DNN is LADN, if AMF determines the terminal except the service range of the corresponding LADN of the session, then refuses to switch the session, if AMF determines the end End then switches the session within the service range of the corresponding LADN of the session.

AMF judges whether to switch the concrete methods of realizing of session, judges whether to establish with a kind of AMF of above-mentioned application scenarios and ask The method of the session of the DNN asked is similar, can refer to the associated description of the step A- step D in above-mentioned application scenarios one, here not It repeats again.

It should be noted that if AMF determines that refusal switches some session, then AMF notifies SMF to deactivate the session or release The session.Wherein, it deactivates, refers to the user face connection of releasing session, such as port access device (such as RAN equipment) and use The connection of family veil first (such as UPF network element).

It is illustrated below with reference to a specific example.For example, terminal send request message include session 1 mark, The mark of the mark of session 2, the mark of session 3 and session 4, the request message is for requesting the switching session 1, session 2, session 3 and session 4.

With reference to Fig. 4, if terminal initiates the request message of the switching session in the cell1 in the service range of LADN1, The method that AMF1 uses aforementioned scene one determines switching session 1, session 2 and session 3, and does not switch session 4.

In turn, the mark of the mark of session 1 and session 3 can be sent to SMF1 by AMF1, switch the session 1 for requesting With session 3, and the mark of session 2 is sent to SMF2, switches the session 2 for requesting.For session 4, due to determining not Switch the session, therefore the mark of the session 4 is sent to SMF1 by AMF1, deactivates or discharge the session 4 for requesting.

The mark of session 1 is sent to SMF1 by AMF1, switches the session 1 for requesting；

The mark of session 2 is sent to SMF2 by AMF1, switches the session 2 for requesting；

The mark of session 3 is sent to SMF1 by AMF1, switches the session 3 for requesting；

The mark of session 4 is sent to SMF1 by AMF1, deactivates or discharge the session 4 for requesting.

The mark of the mark of session 1 and session 3 is sent to SMF1 by AMF1, switches the session 1 and session 3 for requesting, And the mark of session 4 is sent to SMF1, the session 4 is deactivated or discharged for requesting；

The mark of session 2 is sent to SMF2 by AMF1, switches the session 2 for requesting.

It further, optionally, can also be to if AMF determines one or more sessions not in switching request message The access device of terminal access sends third and indicates that information, third instruction information are used to indicate refusal and switch the session.

For example, being directed to above-mentioned example, AMF1 can also send third to terminal and indicate information, wrap in third instruction information The mark for including session 4 is used to indicate refusal and switches the session 4.

In this scenario, after AMF receives the request of switching session of terminal, first determine whether terminal whether LADN's Except service range.If it is determined that terminal except the service range of LADN, then directly refuses the request of the switching session of the terminal, Rather than first switch the session and discharge again, to reduce the resource occupation for switching invalid session, help to reduce resource wave Take.

Combined with specific embodiments below, message explanation is carried out to the above method.

As shown in figure 5, being a kind of schematic diagram of conversation processing method provided by the present application.The embodiment corresponds to above-mentioned application Scene one.Wherein, terminal initiates a session establishment request, establishes a session for requesting, session establishment request is A kind of specific example of above-mentioned request message.
