In view of the foregoing technical problems, an embodiment of the present invention provides an information processing method, which may be specifically implemented as a Group redirection method based on a Group AMBR (maximum aggregation rate of packets) and a UPF load in an access process; mainly relates to a method for a GMF (Group resource management framework) to reselect a Group for UE to access when a UE (terminal) accesses a certain Group and exceeds the maximum load of the Group AMBR or the UPF under a 5G LAN (local area network) networking. The process may be completed through redirection, that is, the GMF establishes the number of service failures according to the load condition (corresponding to the load information) of each other Group (i.e., a Group other than the current Group (which may also be understood as a load Group)), the duration of the UE staying in each other Group (corresponding to the terminal staying duration within a period of time), and each other Group, sorts the remaining groups (i.e., the other groups), and sends the sorted list to the terminal as a reference for terminal re-access, where the weight occupied by each factor during the sorting may be defined according to an actual condition. The Group may specifically be a 5G LAN Group.

The scheme provided by the embodiment of the invention is explained in two scenes, namely a processing method for exceeding the Group AMBR after the UE is accessed and a processing method for exceeding the maximum load of the UPF after the UE is accessed.

In a first scenario, a processing method of UE exceeding a Group AMBR after access;

as shown in fig. 5, the scheme provided by the embodiment of the present invention specifically includes:

step 51: APP requests 5G LAN service, triggering PDU session establishment request;

specifically, the UE requests a 5G LAN service (corresponding to the above-mentioned request for obtaining local area network service) in the APP, and triggers a PDU session establishment request; the APP is borne on the UE.

Step 52: the UE sends a PDU Session establishment request (corresponding to the PDU Session establishment request information) to the SMF, wherein the PDU Session request can contain a PDU Session ID (PDU Session identification) and a Group ID (Group identification), and the like;

step 53: SMF sends PDU Session establishment request to GMF, the Session request can have PDU Session ID and Group ID;

step 54: the GMF evaluates that the PDU session is established by GBR (guaranteed rate) service, and if the establishment is successful, the Group of AMBRs will exceed the preconfigured upper limit Group AMBR (the rate required by the terminal is greater than the remaining available rate corresponding to the current lan Group, i.e. the rate required by the terminal plus the rate of the existing service is greater than the upper limit Group AMBR);

step 55: the GMF refuses the PDU conversation application, and sorts the rest groups (namely other groups) according to the load condition of each other (5G LAN) Group, the residence time of the UE in each other Group (within a period of time) and the service establishment failure times of each Group, and sends the sorted list to the terminal as the reference for the terminal to re-access, and the weight occupied by each factor during sorting can be defined according to the actual condition;

step 56: the GMF sends PDU session establishment failure (corresponding to the PDU session establishment failure information) to the SMF, which may include a failure reason (for overload) and a recommended Group ID list (corresponding to the ordered list, or a part or all of the ordered list);

and 57: SMF sends PDU session establishment failure to UE, which may include failure reason (overload) and recommended Group ID list;

step 58: the UE acquires the Group ID list recommended by the network on the App, and can select a proper Group to initiate the PDU session establishment request again (corresponding to the above-mentioned re-determining the target local area network Group according to the Group sorting information; and initiating the PDU session establishment request to the SMF network element according to the re-determined target local area network Group).

A second scenario is a processing method for exceeding the maximum load of the UPF after the UE is accessed;

as shown in fig. 6, the scheme provided by the embodiment of the present invention specifically includes:

step 61: APP requests 5G LAN service, triggering PDU session establishment request;

specifically, the UE requests 5 a GLAN service (corresponding to the above local area network service acquisition request) in the App, and triggers a PDU session establishment request;

step 62: UE sends PDU conversation to SMF to set up the request (corresponding to the above-mentioned PDU conversation to set up the solicited information), PDU conversation can have PDU Session ID and Group ID, etc. in the request;

and step 63: SMF sends PDU Session establishment request to GMF, the Session request can have PDU Session ID and Group ID;

step 64: the GMF evaluates that the PDU session is established as a GBR service, and if the establishment is successful, the AMBR of the Group does not exceed a pre-configured upper limit Group AMBR; then, the GMF replies a PDU session setup success message (corresponding to the above PDU session setup success message) to the SMF;

step 65: SMF sends session establishment request of N4 port (corresponding to the session establishment request information of the interface) to UPF;

and step 66: the UPF evaluates that the PDU session is established by GBR service, and if the establishment is successful, the maximum load of the UPF is exceeded (the load required to be established corresponding to the terminal is greater than the remaining bearable load corresponding to the current user plane network element). Thus, the UPF replies to the SMF that the session establishment of port N4 failed (corresponding to the above-mentioned interface session establishment failure information), and may carry the reason for the failure (for overload);

step 67: SMF applies for a Group ID sorting list from GMF and can carry an overload UPF ID (corresponding to the failure information established according to the interface session, a Group sorting information request is sent to the control plane network element, wherein the Group sorting information request carries an overload user plane network element identifier);

step 68: the GMF establishes service failure times for each Group according to the load condition of each other (5G LAN) Group except the Group corresponding to the UPF (namely the current UPF), the residence time of the UE in each other Group (within a period of time), and the Group, and sorts the other groups to obtain a sorted list; the weight occupied by each factor in sorting can be defined according to the actual situation;

step 69: the GMF feeds back a Group ID list (corresponding to the ordered list, or part or all of the ordered list) to the SMF;

step 610: SMF replies PDU conversation to UE and establishes failure, and can carry failure reason (for overload) and recommended Group ID list;

step 611: the UE acquires the Group ID list recommended by the network on the App, and can select a proper Group to initiate the PDU session establishment request again (corresponding to the above-mentioned re-determining the target local area network Group according to the Group sorting information; and initiating the PDU session establishment request to the SMF network element according to the re-determined target local area network Group).

It should be noted that, the scheme shown in fig. 6 is an example of a processing method for performing the UPF to determine the maximum overload on the basis that the GMF determines that the PDU session is successfully established in the first scenario, and of course, the processing method for determining the maximum overload may also be used alone, that is, the GMF does not perform the determination on whether the maximum overload exceeds the upper limit Group AMBR any more, but only the UPF determines whether the maximum overload exceeds the maximum overload, which may specifically refer to the relevant content in fig. 6, and is not described herein again. The RAN referred to in fig. 5 and 6 above denotes a Radio Access Network (Radio Access Network).

As can be seen from the above, the scheme provided by the embodiment of the present invention mainly relates to:

(1) UE sends PDU Session establishment request of guaranteeing rate to GMF through SMF, the Session request can have PDU Session ID and Group ID;

(2) the GMF judges that if the request is successfully established, the request exceeds a pre-configured Group AMBR or the UPF judges that if the request is successfully established, the request exceeds the maximum load of the UPF; the GMF rejects the PDU session application, and according to the load condition of each other Group, the residence time of the UE in the threshold time of each other Group and the service failure times established by each other Group, sorts the rest groups (i.e. other groups) to generate a Group ID list, otherwise, executes (5);

(3) the GMF sends PDU conversation establishment failure information and the Group ID list generated in the step (2) to the UE through the SMF;

(4) and (3) the UE reselects a proper Group to initiate the PDU session establishment request of the guaranteed rate again according to the Group ID list generated in the step (2), namely returning to the step (1).

(5) The session request is successfully established.

To sum up, the scheme provided by the embodiment of the present invention involves:

when the 1.5G LAN service is accessed, the Group AMBR judgment is carried out on the GBR service in the GMF, and the load judgment is carried out in the UPF;

2. and if the GBR service exceeds the Group AMBR after being successfully established or exceeds the maximum load of the UPF, carrying out Group redirection.

3. The GMF sorts the other groups according to the load conditions of each other Group except the Group (or the Group corresponding to the UPF), the residence time of the UE in each other Group (within a period of time), and the service establishment failure times of each other Group, and determines a redirected candidate Group. The weight of each factor in the ranking can be defined according to actual conditions.

4. And the UE selects a Group for re-access according to the Group list suggested by the network side.

In summary, there is no access control in the existing solutions regarding the overload of groups in 5G LANs, in particular no functionality to redirect group re-access due to access group failure. If the user service application is rejected due to the overload of the group or the UPF, the user can repeatedly apply on the same group, air interface resources are wasted, the user service perception is influenced, and the industrial production progress can be delayed in the local area network application in the industrial field. In the scheme, a Group redirection method based on a Group AMBR and UPF load in the access process is provided, and the Group redirection method is mainly used for analyzing according to the Group and UPF load information of a network side and the access success rate direction of the UE and providing a Group ID list for the access of the UE; and the UE is prevented from continuously and blindly accessing the invalid group.
