Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flowchart of a session processing method provided by an embodiment of the present invention. Applied to a terminal, the session processing method may include:

Step 101: The terminal receives a session release message sent by a session management function entity (Session Management Function, SMF); wherein, the session release message includes a backoff time value and identification information, and the identification information is used to indicate insufficient resources (insufficient resources);

Specifically, when the resources of the first network are insufficient, the SMF will send a protocol data unit (Protocol Data Unit, PDU) session release message (SESSION RELEASE COMMAND) to the terminal, and the session release message carries a backoff time value (Backoff time) , the Backoff time is generally not 0, and the Backoff time is used to indicate that the terminal cannot initiate a PDU session establishment request or a session modification request on the same Data Network Name (Data Network Name, DNN) within the Backoff time; in addition, the The session release message also carries identification information for indicating insufficient resources.

Step 102: The terminal compares the backoff time value with a preset threshold value;

In the embodiment of the present invention, considering that within the Backoff time, the terminal cannot obtain any service through the PDU session, especially when the value of the Backoff time is very large, the user experience is not good; in order to solve the problem of poor user experience To solve the problem, the preset threshold value is used to determine under what circumstances the terminal waits for the Backoff time to expire, which will reduce the user experience; and before the Backoff time expires, a session establishment request is initiated through available resources, thereby avoiding the long-term user experience. The problem of time waiting is improved, and the user experience is improved. Wherein, the preset threshold value is time, within which time the user will not feel the waiting, so there is no problem of bad user experience.

Step 103: When the backoff time value is greater than the preset threshold value, end waiting for the backoff time value, and initiate a session establishment request through available resources; where the available resources are unoccupied network resources.

It is mentioned in step S102 that if the Backoff time is greater than the preset threshold value, user experience will be affected because the user waits for too long. Then step 103 is to finish waiting for the Backoff time before the Backoff time expires, and initiate a session establishment request through available resources, thereby improving user experience.

In the embodiment of the present invention, the session establishment request initiated by an unoccupied network resource in step 103 includes the following situations:

The first case: the unoccupied network resource is the network resource of the second network.

Specifically, switch from the current first network to the second network; in the second network, use the network resources of the second network to initiate a session establishment request.

In the second network, after the session establishment request is initiated, if the backoff time value expires and the working mode is the idle mode, switch back to the first network.

Specifically, after step 102, start the timing device of the terminal, and its period is Backofftime, for example, a timer; when the Backoff time expires, that is, the timer expires, and the operating mode of the terminal is idle mode idle, switch back to first network.

The second case: the unoccupied network resource is a specific slice resource.

Wherein, the identification information is first identification information, and the first identification information is used to indicate insufficient resources for specific slices;

Specifically, the terminal determines available Single Network Slice Selection Assistance Information (S-NSSAI) resources; and based on the available S-NSSAI resources, initiates a session establishment request; where the available S-NSSAI resources are used for Indicates the specific tile resources available.

In the embodiment of the present invention, before initiating a session establishment request based on available S-NSSAI resources, it also includes: judging whether there are available S-NSSAI resources; The network switches to the second network; in the second network, a session establishment request is initiated.

The third case: the unoccupied network resources are specific slices and available DNN resources.

Wherein, the identification information is second identification information, and the second identification information is used to indicate that specific slice resources and DNN resources are insufficient (insufficient resources for specific slice and DNN);

Specifically, the terminal determines available S-NSSAI resources and available DNN resources; wherein, the available S-NSSAI resources are used to indicate available specific slice resources; and based on available S-NSSAI resources and available DNN resources , initiate a session establishment request.

In this embodiment of the present invention, before initiating a session establishment request based on available S-NSSAI resources and available DNN resources, it further includes: judging whether there are available S-NSSAI resources and available DNN resources at the same time, and if there are no available S-NSSAI resources and available DNN resources. -NSSAI resources and available DNN resources are switched from the current first network to the second network; in the second network, a session establishment request is initiated. Wherein, the above-mentioned specific slice resource is a network slice.

In the second network, after the session establishment request is initiated, if the backoff time value expires and the working mode is the idle mode, switch back to the first network.

Specifically, after step 102, start the timing device of the terminal, the period of which is Backoff time, for example, a timer; when the Backoff time expires, that is, the timer expires, and the working mode of the terminal is the idle mode idle mode, switch Back to the first network.

It should be noted that after switching to the second network, the available resources of the second network are used to initiate a session establishment request; when the Backoff time expires and the working mode of the terminal is idle mode, the terminal is switched back to the first network. Moreover, the switching between the first network and the second network is very fast, and the user will not be aware of sudden changes in the network, thereby improving user experience.

In the embodiment of the present invention, if the Backoff time is less than or equal to the preset threshold value, wait for the Backoff time to expire, that is, the timer expires, and re-initiate the session establishment request.

It should be noted that, when the Backoff time is relatively small, the original DNN can be used to re-initiate the session establishment request after the Backoff time expires; the original DNN is used to establish the session released due to insufficient resources.

The purpose of using an unoccupied network is to provide uninterrupted session service. Therefore, as long as the above objects can be achieved, they can all be included in the scope of the embodiments of the present invention.

In the embodiment of the present invention, the backoff time value included in the session release message and the identification information used to indicate insufficient resources are used. The session establishment request is re-initiated, thereby ensuring the continuity of the session service and improving user experience at the same time.

In the embodiment of the present invention, both the first network and the second network are two types of networks currently used, the first network may be the fifth generation mobile communication technology (5-Generation, 5G), and the second network may be the fourth A network in the first generation mobile communication technology (4-Generation, 4G), the third generation mobile communication technology (3-Generation, 3G) or the second generation mobile communication technology (2-Generation, 2G).

It should be noted that before switching from 5G to 4G, 3G or 2G, the terminal can give priority to 4G with higher priority. After considering the priority, it also needs to consider the network status. After combining the priority and network status, choose to switch to a network that has both.

The following uses 5G (first network) and 4G (second network) to illustrate how to solve the problem of session failure when 5G resources are insufficient.

Using the embodiment of the present invention, when the 5G network resources are insufficient and the Backoff time is greater than the preset threshold, a session establishment request is initiated through the available resources, thereby solving the problem of session failure when the network resources are insufficient.

Fig. 2 is a flowchart of another session processing method according to an embodiment of the present invention. As shown in Figure 2, the session processing method includes:

Step 201: The terminal receives the session release message sent by the SMF, the session release message includes Backoff time and identification information, the identification information is used to indicate that 5G resources are insufficient;

Step 202: The terminal compares whether the Backoff time is greater than or equal to the preset threshold threshold; when the Backoff time is less than or equal to the threshold, perform step 203; when the Backoff time is greater than the threshold, perform steps 204, 205, and 206;

Step 203: After waiting for the timer to expire (at this time, the period of the timer is Backoff time), then set up a PDU session establishment request;

It should be noted that when the Backoff time is relatively small, the original DNN can be used to re-initiate the session establishment request after the Backoff time expires; the original DNN is used to establish a session released due to insufficient resources.

Step 204: The terminal performs inter-rat selection again, and switches from 5G to 4G.

After the Backoff time expires and the working mode of the terminal is idle, switch to 5GC and continue to use 5G services.

Specifically: choose to connect to the evolved packet core network (Evolved Packet Core Network, EPC) to obtain services, and after the Backoff time expires, and when the working mode of the terminal is idle, switch to 5GC and continue to use 5G services. It ensures that users can continue to use the service, and after the 5G network is restored, the terminal automatically switches back to 5G.

It should be noted that in the 4G network, a session establishment request of an Access Point Name (APN) is initiated to ensure that the user can still continue to establish a session when the 5G network resources are insufficient.

Step 205: When the identification information is insufficient resources for specific slice and DNN, the terminal replaces the S-NSSAI resource and the DNN resource, and initiates a PDU session establishment request of other DNN (different from the original DNN).

Step 206: When the identification information is insufficient resources for specific slice, the terminal replaces the S-NSSAI resource, and initiates the original DNN PDU session establishment request.

It should be noted that when the S-NSSAI resources given by the 5G system are insufficient, the terminal re-initiates the PDU session establishment request of different DNNs by replacing the available S-NSSAI resources, and then re-acquires 5G services.

In the embodiment of the present invention, when 5G network resources are insufficient, service continuity is obtained by selectively switching between different systems or re-initiating PDU session establishment requests of different DNNs. This ensures continuous user service and adapts to network congestion.
