Background technique
UE (User Equipment, user terminal) passes through 3GPP (3rd Generation Partnership
Project, third generation partner program) access and non-3 GPP access be connected to core net the network architecture it is as shown in Figure 1.Figure
In 1 respectively mark be explained as follows:
HPLMN (Home Public Land Mobile Network, local public land mobile network)；
AMF (Access Control And Mobility Management Function, access control and mobility
Management function)；
SMF (Session Management Function, conversation management functional)；
IWF (Inter Working Function, interoperate function)；
UPF (User Plane Function, user plane functions)；
N1, N2, N3, N4, N6, N11, NWu, Y1 and Y2 are the communication interface in the network architecture.
For being connected to the UE of 3GPP access and non-3 GPP access simultaneously, if UE enters the free time in non-3 GPP access
State, when UPF receives the downlink data for the PDU session established in non-3 GPP access, UPF sends downlink data to SMF and leads to
Know message.SMF sends N11 request message to AMF, and when UE is in Idle state in non-3 GPP access, AMF is sought in 3GPP access
UE is exhaled, carries wireless access type in paging message.
When UE receives paging message, UE accesses initiating business request process by 3GPP, carries in business request information
The PDU session identification of 3GPP access is established and can be moved into non-3 GPP access.After AMF receives the message, AMF sentences
Disconnecting receives the PDU session identification of downlink data whether in the PDU session identification list that UE is provided, if continuing to hold
Row service request procedure；If it was not then AMF returns to refuse information to UE and SMF respectively.
As it can be seen that in the prior art, network (network is, for example, mobile network) is not known in session management procedure
Whether UE, which wishes to access by 3GPP, is established certain PDN connection, and directly accesses paging UE by 3GPP；When UE receives paging
And when initiating service request procedure, whether mobile network just can get UE and wishes to access the information for establishing the connection by 3GPP,
In this way, still being paged, therefore, in the session management procedure even if UE, which is not intended to access by 3GPP, establishes the connection
There is technical issues that paging.

Specific embodiment
In order to solve the above-mentioned technical problem, the general thought of the technical solution in the embodiment of the present invention is as follows:
A kind of conversation managing method and device, when UE is in Idle state in the non-3 GPP access, if receiving needle
Whether the data notification request to PDU session of the UE in the non-3 GPP access then can according to the characterization that is used for of acquisition
The enough information that the PDU session is reactivated in 3GPP access, which judges whether to access by the 3GPP, pages the UE or logical
It crosses the 3GPP and accesses and send a notification message to the UE, or whether can be connect in the non-3 gpp further combined with the UE
Enter the interior connected state that enters to judge whether to access the paging UE by the 3GPP.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
As shown in Fig. 2, the embodiment of the present invention one provides a kind of conversation managing method, include the following steps:
When S201, user terminal UE are in Idle state in non-3 GPP access, if received for the UE described
Whether the data notification of the PDU session in non-3 GPP access is requested, then can be in 3GPP access according to the characterization that is used for of acquisition
The information for reactivating the PDU session judges whether that the PDU session can be reactivated in 3GPP access；
S202, if it is possible to the PDU session is reactivated in 3GPP access, by described in 3GPP access paging
UE。
For in step S201 judge whether can 3GPP access in reactivate the PDU session, sentenced
It has no progeny, if the PDU session can not be reactivated in 3GPP access, this method may include the following two kinds embodiment party
Formula determines whether to page UE, specifically:
Mode one: issuing replying message for data notification request, described to reply message middle carrying Reason For Denial.
As shown in figure 3, the specific method for paging UE is for mode one:
Execute step S301, wherein the step S301 is identical with the step S201；
If it is determined that the PDU session can be reactivated in 3GPP access, step S302 is executed, the 3GPP is passed through
The UE is paged in access；
If it is determined that the PDU session can not be reactivated in 3GPP access, the step S303a is executed, is issued
It is described to reply message middle carrying Reason For Denial for replying message for data notification request.
Mode two: based on whether there is available non-3 GPP access around the UE, judge whether through the 3GPP
The UE is paged in access；
If there are available non-3 GPP access around the UE, the UE is paged by 3GPP access；
If available non-3 GPP access is not present around the UE, the reply for data notification request is issued
Message, it is described to reply message middle carrying Reason For Denial.
In mode two, it can judge to connect with the presence or absence of available non-3 gpp around the UE by following two mode
Enter, to judge whether that (the following are citings, not exhaustive, can also be using other this fields by 3GPP access paging UE
The mode that technical staff can appreciate that is to determine whether page the UE by 3GPP access):
Mode 2a: judge to be based on the UE institute with the presence or absence of available non-3 GPP access around the position where the UE
Position, judge around the position where the UE with the presence or absence of available non-3 GPP access.Specifically, if it is determined that institute
There are available non-3 GPP access for the position for stating where UE, pass through 3GPP access and page the UE.
If it is determined that available non-3 GPP access is not present in the position where the UE, issues and asked for the data notification
That asks replies message, described to reply message middle carrying Reason For Denial.
Specifically, mobile network voluntarily judges to whether there is non-3 GPP access around UE according to the location information of UE, from
And judges whether to access by the 3GPP and page the UE.
For example, AMF can get the corresponding relationship between 3GPP access covering and non-3 GPP access covering.If where UE
Position (such as 3GPP cell) is there are the covering of available non-3 GPP access, then AMF thinks that there are non-for the current location where UE
Non-3 GPP access is not present in 3GPP access, the current location where otherwise AMF thinks UE.
Alternatively, network deployment information of the AMF according to configuration, judges that the current position UE is non-with the presence or absence of allowing UE to use
3GPP accesses network.Network dispose Examples of information:<cell 1, cell 2>available non-3GPP access network be WLAN1,<cell
2, cell 3 > available non-3GPP access network be WLAN2.
Alternatively, if UE current location stopped a period of time, but UE non-3 GPP access state still in sky
Not busy state, AMF think that there is no available non-3GPP access networks around UE.
Mode 2b: the message for whether monitoring available non-3 GPP access sent based on the UE received, judgement
Whether the 3GPP access paging UE is passed through.Specifically, if monitoring of receiving that the UE sends is available non-
The message of 3GPP access then pages the UE by 3GPP access；Alternatively, if receiving not monitoring for the UE transmission
To the message of available non-3 GPP access, then issue replying message for data notification request, it is described to reply message
Carry Reason For Denial.
Specifically, for example, UE is in after Idle state in non-3 GPP access, UE constantly monitors the available non-3 gpp of surrounding
The information of access, if UE does not monitor the information of available non-3 GPP access, UE sends a notification message to AMF, which disappears
Prompt information is carried in breath, which shows that there is no available non-3 GPP access around the UE.PDU of the AMF in UE
The information is stored in the context of session, and is replied message to UE.Wherein, it replies message to UE as optional step,
AMF can not also be replied message to UE.
When UE monitors available non-3 GPP access, if UE is not intended to immediately enter connected state, (such as no data is passed
Defeated demand), UE sends a notification message to AMF, carries prompt information in the notification message, which shows around the UE
There are available non-3 GPP access.AMF updates the contextual information of the PDU session of UE.
Before carrying out step S201 or S301, this method can also include:
It is established in non-3 GPP access in PDU conversation procedure in the UE, whether obtain the UE transmission is used for characterization
The information of the PDU session can be reactivated in 3GPP access.
Specifically, when UE establishes PDU session by non-3 GPP access, NAS (Non-access that UE is sent to AMF
Stratum, Non-Access Stratum) in message, other than carrying the parameters such as PDU session id, PDU session request, also carries and whether lead to
Cross the information that 3GPP access reactivates the PDU session.After AMF receives the information, AMF is stored in the context of UE
The information.
Whether can to reactivate the information of PDU session be to be directed in 3GPP access in order to guarantee that mobile network obtains
The corresponding PDU session of the information needs the information that the PDU session whether can be reactivated in 3GPP access to acquisition
It is safeguarded, the mode of maintenance is, for example:
If 1) PDU session has been established in the UE in the non-3 GPP access, issued based on the UE received
Registration information is obtained for characterizing the modified PDU meeting of update that whether can be reactivated in 3GPP access
The information of words；Wherein, whether carry in the login request message can reactivate institute in 3GPP access for characterizing
State the information of modified PDU session.
If UE is in connected state in non-3 GPP access, which sends login request message to shifting by non-3 GPP access
Dynamic network, for mobile network whether according to the login request message, modified PDU can be reactivated in 3GPP access by obtaining
The information (while deleting original information or new information can cover original information) of session, and mobile network is to the UE
Return to registration received message.
If UE is in Idle state in non-3 GPP access, which is accessed by 3GPP sends login request message to movement
Network, for mobile network whether according to the login request message, modified PDU meeting can be reactivated in 3GPP access by obtaining
The information (while deleting original information) of words, and mobile network returns to registration received message to the UE.
Specifically, for example, UE establishes PDU session by non-3 GPP access, PDU session establishment process is as follows:
The PDU session that process 1:UE is established can be accessed by 3GPP and be reactivated；
PDU session is established in 1.1 UE request, UE to AMF sends PDU session identification, request message is established in PDU session 1, with
And the prompt information reactivated can be accessed by 3GPP for characterizing the PDU session.
1.2 AMF store PDU session identification and the PDU session in the context of UE and can be accessed by 3GPP and be swashed again
Information living.Assuming that the PDU session during this is PDU session 1.
The PDU session that process 2:UE is established can not be accessed by 3GPP and be reactivated；
PDU session is established in 2.1 UE request, UE to AMF sends PDU session identification, request message is established in PDU session 1, with
And the PDU session can not access the prompt information reactivated by 3GPP.
2.2 AMF store PDU session identification in the context of UE and can not pass through for characterizing the PDU session 1
3GPP accesses the information reactivated.Assuming that the PDU session during this is PDU session 2.
After the process that executed 1 and process 2, the registration process of UE is as follows:
A) UE sends login request message to AMF, and message parameter includes reactivating for characterizing to access by 3GPP
PDU session information or the information of PDU session that 3GPP access reactivates can not be passed through；PDU session herein can refer to
PDU session 1 and/or PDU session 2 above-mentioned.
B) AMF modifies the information that the AMF is stored in the context of UE according to above- mentioned information, and returns to registration to UE and receive
Message.
After the process that executed 1 and process 2, the context of the UE of AMF storage includes: UE mark, and < PDU session 1 can lead to
Cross 3GPP access reactivate>,<PDU session 2, can not by 3GPP access reactivate>；
In the registration process for executing UE, it is assumed that " can be accessed and being reactivated by 3GPP in the message that UE is sent to AMF
PDU session " information include PDU session 1 and PDU session 2.After then having executed registration process, the UE that is stored in AMF up and down
Text are as follows: UE mark,<PDU session 1, can be reactivated by 3GPP access>,<PDU session 2 can be accessed by 3GPP and be swashed again
Living >.
Assuming that the packet of " the PDU session reactivated can not be accessed by 3GPP " in the message that UE is sent to AMF
Include PDU session 1 and PDU session 2.After then having executed registration process, the context of the UE stored in AMF are as follows: UE mark, < PDU
Session 1, can not be reactivated by 3GPP access>,<PDU session 2, can not be reactivated by 3GPP access>.
Assuming that the information of " can access the PDU session reactivated by 3GPP " in the message that UE is sent to AMF includes
PDU session 2.After then having executed registration process, the context of the UE stored in AMF are as follows: UE mark, < PDU session 1 can not lead to
Cross 3GPP access reactivate>,<PDU session 2, can by 3GPP access reactivate>.
2) when the PDU session is released, that deletes acquisition is used for whether characterization can to reactivate in 3GPP access
The information of the PDU session.Specifically, for example, whether acquisition can be reactivated institute in 3GPP access by mobile network
The information for stating PDU session is stored, if the PDU session is released, whether illustrate storage can access interior weight in 3GPP
It newly activates the information of the PDU session useless, then deletes the information of storage.Such as when the PDU session of UE is mobile
To after 3GPP access, AMF deletes the information received.UE locally also deletes the information.
3) when the PDU session is reactivated in 3GPP access, whether capable of for characterizing for acquisition is deleted
The information of the PDU session is reactivated in 3GPP access.Specifically, for example, mobile network by acquisition whether can be
The information that the PDU session is reactivated in 3GPP access is stored, when PDU session is reactivated in 3GPP access,
The information that the PDU session whether can be reactivated in 3GPP access stored in mobile network is useless, then deletes
Except the information of storage.
Above- mentioned information maintenance is that whether capable of reactivating in 3GPP access for characterizing for the UE transmission obtained
It is carried out after the information of the PDU session, can be and whether capable of connecing in 3GPP for characterizing for the UE transmission obtained
Any moment after the information of the PDU session is reactivated in entering, and in case of above-mentioned three kinds of situations, then carries out information
Maintenance.Specifically, such as what the acquisition UE was sent whether the PDU can be reactivated in 3GPP access for characterizing
After the information of session and before executing step S201；Or obtaining that the UE sends for whether characterize can be
The information of the PDU session is reactivated in 3GPP access, and performs step S201 and S202 and has carried out others again later
After step, the maintenance of information is carried out.It is only for example herein, is not specifically to limit.
Referring to fig. 4, in order to better understand the present embodiment, conversation managing method is illustrated, UE is in non-3 gpp
Idle state is in access, for the PDU session that UE is established by non-3 GPP access, specific step is as follows for this method:
S401, AMF receive the data notification request that SMF is sent, and the ID of PDU session is carried in data notification request.
Data notification request e.g. SMF sends N11 message to AMF, carries PDU session id in message.Specifically,
When UPF receives downlink data (in PDU session there is no the corresponding RAN of the downlink data (Radio Access Network,
Wireless access network) information), UPF sends the notification message for being directed to the downlink data to SMF, and PDU meeting is carried in the notification message
Talk about ID；According to the notification message, SMF sends N11 message to AMF, which shows that mobile network requires to send downlink to UE
Data；
S402 judges whether that the PDU session can be reactivated by 3GPP access.Wherein, which passes through non-
The PDU session that 3GPP access is established.Specifically, whether AMF can be in 3GPP be accessed again according to the characterization that is used for that UE is sent
The information for activating the PDU session, is judged.According to judging result, it can specifically be divided into two kinds of situations:
If the PDU session can be activated, step S403a is executed, AMF pages the UE by 3GPP access.That is AMF to
RAN sends paging message.
If the PDU session can not be activated, step S403b is executed, AMF sends N11 message to SMF, refuses the data of SMF
Notice is requested, and is carried Reason For Denial in the N11 message, i.e., can not be paged.
After executing S403b, SMF sends to UPF and abandons downlink data notification.UPF abandons it after receiving the message
The downlink data received.
Alternatively, in step S403b, can further by judge the UE whether can in the non-3 GPP access into
Enter connected state, pages the UE to decide whether to access by 3GPP.
As shown in Figure 5A, second embodiment of the present invention provides a kind of session management devices, comprising:
First judgment module 501, when being in Idle state in non-3 GPP access for user terminal UE, if receiving needle
Whether the data notification request to PDU session of the UE in the non-3 GPP access then can according to the characterization that is used for of acquisition
The enough information that the PDU session is reactivated in 3GPP access judges whether to reactivate in 3GPP access described
PDU session；
First sending module 502, if for the PDU session can be reactivated in 3GPP access, by described
3GPP access to the UE send paging message with the 3GPP access in page the UE or by the 3GPP access to
The UE sends a notification message；Wherein, it is accessed by the 3GPP and sends paging message to the UE and pass through the 3GPP and connect
Enter the interior paging UE.
After first judgment module 501 judges whether that the PDU session can be reactivated in 3GPP access, if not
The PDU session can be reactivated in 3GPP access, then described device can also include that following module determines whether to page
UE is specifically divided into two kinds of implementations:
As shown in Figure 5 B, mode one, the device further include the second sending module 503, issue and ask for the data notification
That asks replies message, described to reply message middle carrying Reason For Denial.
As shown in Figure 5 C, mode two, the device further include the second judgment module 504 based on whether there is around the UE
Available non-3 GPP access judges whether to access by the 3GPP and pages the UE.
Specifically, which further includes the second paging module and/or third sending module, if the second paging module is used for
There are available non-3 GPP access around the UE, page the UE by 3GPP access.Third sending module, is used for
If available non-3 GPP access is not present around the UE, replying message for data notification request, institute are issued
It states and replies message middle carrying Reason For Denial.
Wherein, second judgment module 504 includes the first judging submodule or second judgment submodule:
First judging submodule, for based on around the position where the UE whether there is available non-3 gpp
Access judges whether to access by the 3GPP and pages the UE；
Specifically, which judges around the position where the UE with the presence or absence of available non-3 gpp
It accesses around the position where judging the UE based on the position where the UE with the presence or absence of available non-3 GPP access.
Specifically, if it is determined that there are available non-3 GPP access for the position where the UE, by described in 3GPP access paging
UE。
If it is determined that available non-3 GPP access is not present in the position where the UE, issues and asked for the data notification
That asks replies message, described to reply message middle carrying Reason For Denial.
Specifically, for example, the first judging submodule voluntarily judges around UE according to the location information of UE with the presence or absence of non-
3GPP access pages the UE to judge whether to access by the 3GPP.
AMF can get the corresponding relationship between 3GPP access covering and non-3 GPP access covering.If the position where UE
(such as 3GPP cell) there are the covering of available non-3 GPP access, then AMF thinks that there are non-3 gpp to connect for the current location where UE
Enter, non-3 GPP access is not present in the current location where otherwise AMF thinks UE.
Whether the second judgment submodule monitors available non-3 gpp for what is sent based on the UE received
The message of access judges whether to access by the 3GPP and pages the UE.
Specifically, if the message for monitoring available non-3 GPP access that the UE is sent is received, by described
The UE is paged in 3GPP access；Alternatively, if receiving the message for not monitoring available non-3 GPP access that the UE is sent,
Replying message for data notification request is then issued, it is described to reply message middle carrying Reason For Denial.
Specifically, for example, UE is in after Idle state in non-3 GPP access, UE constantly monitors the available non-3 gpp of surrounding
The information of access, if UE does not monitor the information of available non-3 GPP access, UE sends a notification message to AMF, which disappears
Prompt information is carried in breath, which shows that there is no available non-3 GPP access around the UE.PDU of the AMF in UE
The information is stored in the context of session, and is replied message to UE.Wherein, it replies message to UE as optional step,
AMF can not also be replied message to UE.
When UE monitors available non-3 GPP access, if UE is not intended to immediately enter connected state, (such as no data is passed
Defeated demand), UE sends a notification message to AMF, carries prompt information in the notification message, which shows around the UE
There are available non-3 GPP access.AMF updates the contextual information of the PDU session of UE.
The device further includes the first acquisition module, judges whether that interior weight can be accessed in 3GPP in first judgment module 501
Before newly activating the PDU session, which establishes in PDU conversation procedure in the UE in non-3 GPP access,
Obtain the UE transmission is used to characterize the information that the PDU session whether can be reactivated in 3GPP access.Specifically,
When UE establishes PDU session by non-3 GPP access, in the NAS message that UE is sent to AMF, in addition to carrying PDU session id, PDU
Outside the parameters such as session request, the information that the PDU session whether is reactivated by 3GPP access also carried.When AMF is received
After the information, AMF stores the information in the context of the PDU session of UE.
In order to which the information that whether can reactivate PDU session in 3GPP access for guaranteeing that the first acquisition module obtains is
For the corresponding PDU session of the information, need whether the PDU session can be reactivated in 3GPP access to acquisition
Information is safeguarded that the mode of maintenance is, for example:
(1) device further includes the second acquisition module, it is described obtain that the UE sends for whether characterize can be
After the information for reactivating the PDU session in 3GPP access, described second obtains module, if for the UE described
PDU session has been established in non-3 GPP access, based on the registration information that the UE received is issued, obtaining for characterizing is
The information of the no updated PDU session that can be reactivated in 3GPP access；Wherein, in the login request message
It carries for characterizing the information that whether can reactivate the modified PDU session in 3GPP access.
If UE is in connected state in non-3 GPP access, the UE is by non-3 GPP access transmission login request message to the
Two obtain module, and according to the login request message, whether the second acquisition module obtains to reactivate in 3GPP access and repair
The information (while deleting original information or new information can cover original information) of PDU session after changing, and mobile network
Network returns to registration received message to the UE.
If UE is in Idle state in non-3 GPP access, which is accessed by 3GPP sends login request message to second
Module is obtained, second obtains module according to the login request message, and whether obtain can reactivate modification in 3GPP access
The information (while deleting original information) of PDU session afterwards, and mobile network returns to registration received message to the UE.
Specifically, for example, UE establishes PDU session by non-3 GPP access, PDU session establishment process is as follows:
The PDU session that process 1:UE is established can be accessed by 3GPP and be reactivated；
PDU session is established in 1.1 UE request, UE to AMF sends PDU session identification, request message is established in PDU session 1, with
And the prompt information reactivated can be accessed by 3GPP for characterizing the PDU session.
1.2 AMF store PDU session identification and the PDU session in the context of UE and can be accessed by 3GPP and be swashed again
Information living.Assuming that the PDU session during this is PDU session 1.
The PDU session that process 2:UE is established can not be accessed by 3GPP and be reactivated；
PDU session is established in 2.1 UE request, UE to AMF sends PDU session identification, request message is established in PDU session 1, with
And the PDU session can not access the prompt information reactivated by 3GPP.
2.2 AMF store PDU session identification in the context of UE and can not pass through for characterizing the PDU session 1
3GPP accesses the information reactivated.Assuming that the PDU session during this is PDU session 2.
After the process that executed 1 and process 2, the registration process of UE is as follows:
A) UE sends login request message to AMF, and message parameter includes reactivating for characterizing to access by 3GPP
PDU session information or the information of PDU session that 3GPP access reactivates can not be passed through；PDU session herein can refer to
PDU session 1 and/or PDU session 2 above-mentioned.
B) AMF modifies the information that the AMF is stored in the context of UE according to above- mentioned information, and returns to registration to UE and receive
Message.
After the process that executed 1 and process 2, the context of the UE of AMF storage includes: UE mark, and < PDU session 1 can lead to
Cross 3GPP access reactivate>,<PDU session 2, can not by 3GPP access reactivate>；
In the registration process for executing UE, it is assumed that " can be accessed and being reactivated by 3GPP in the message that UE is sent to AMF
PDU session " information include PDU session 1 and PDU session 2.After then having executed registration process, the UE that is stored in AMF up and down
Text are as follows: UE mark,<PDU session 1, can be reactivated by 3GPP access>,<PDU session 2 can be accessed by 3GPP and be swashed again
Living >.
Assuming that the packet of " the PDU session reactivated can not be accessed by 3GPP " in the message that UE is sent to AMF
Include PDU session 1 and PDU session 2.After then having executed registration process, the context of the UE stored in AMF are as follows: UE mark, < PDU
Session 1, can not be reactivated by 3GPP access>,<PDU session 2, can not be reactivated by 3GPP access>.
Assuming that the information of " can access the PDU session reactivated by 3GPP " in the message that UE is sent to AMF includes
PDU session 2.After then having executed registration process, the context of the UE stored in AMF are as follows: UE mark, < PDU session 1 can not lead to
Cross 3GPP access reactivate>,<PDU session 2, can by 3GPP access reactivate>.
(2) whether the device further includes removing module, be used for characterization can be in 3GPP what the acquisition UE was sent
After the information for reactivating the PDU session in access, the removing module is released for working as the PDU session, or
When the PDU session is reactivated in 3GPP access, whether capable of accessing in 3GPP for characterizing for acquisition deleted
Inside reactivate the information of the PDU session.
For example, mobile network by acquisition whether can be reactivated in 3GPP access the information of the PDU session into
Row storage, if the PDU session is released, whether illustrate storage can reactivate the PDU session in 3GPP access
Information is useless, then removing module deletes the information of storage.Such as when the PDU session of UE is moved to 3GPP access
Later, removing module deletes the information that AMF is received.UE locally also deletes the information.
Alternatively, mobile network by acquisition whether can be reactivated in 3GPP access the information of the PDU session into
Row storage, when PDU session is reactivated in 3GPP access, whether what is stored in mobile network can access interior weight in 3GPP
Newly activate the information of the PDU session useless, then removing module deletes the information of storage.
In addition, the device is specifically, for example, AMF, the method and step of the working principle of the AMF and the side of embodiment one kind
