[0073] Figure 1 A session establishment system architecture diagram in an embodiment of the present disclosure is shown.
[0074] like Figure 1 As shown, the session establishment system may include:
[0075] A first session management function module 102 and a second session management function module 104;
[0076] The first session management function module 102 is used to respond to a session request sent by the terminal, obtain a bandwidth parameter of a session group in which the terminal is located, the session request includes bandwidth data required for the session, and send the session request to the second session management function module when the bandwidth parameter is less than the contracted bandwidth parameter, and establish a session of the terminal when receiving a first response signal sent by the second management function module, and modify the bandwidth parameter stored locally based on the bandwidth data.
[0077] The second session management function module 104 is configured to, upon receiving a session request, modify bandwidth parameters stored in the second management function module based on bandwidth data in the session request, and send a first response signal to the second management function module.
[0078] In some embodiments, the first session management function module 102 and the second session management function module 104 may be connected via a wired network or a wireless network.
[0079] In some embodiments, the wireless network or wired network described above uses standard communication technology and / or protocols. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network.

In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.
[0080] Based on the same inventive concept, an embodiment of the present disclosure provides a session establishment method. In principle, the method can be executed by any electronic device with computing and processing capabilities.
[0081] Figure 2 A flow chart of a session establishment method provided by an embodiment of the present disclosure is shown. It should be noted that the session establishment method is applied to a first session management function module, and the first session management function module can be any module in the session management system, such as Figure 2 As shown, the session establishment method provided by the embodiment of the present disclosure may include:
[0082] S210 , in response to a session request sent by a terminal, obtaining bandwidth parameters of a session group in which the terminal is located, wherein the session request includes bandwidth data required for the session.
[0083] In one embodiment, the terminal may be a terminal in a session group, and the session group may be a 5G LAN group.
[0084] In one embodiment, the conversation group needs to occupy a certain bandwidth, and the above bandwidth data is the bandwidth data required by the conversation request initiated by the terminal.
[0085] In one embodiment, the bandwidth parameter may be bandwidth data occupied by the other sessions in the session group where the terminal is located.
[0086] In one embodiment, the terminal may be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.
[0087] In one embodiment, the terminal may transmit via a wired network or a wireless network.
[0088] In one embodiment, the first session management function module may include a service management function (SMF) network element.
[0089] S220: When the bandwidth parameter is less than the contracted bandwidth parameter, send a session request to the second session management function module, so that the second session management function module modifies the bandwidth parameter stored in the second management function module based on the bandwidth data.
[0090] In one embodiment, the bandwidth parameter and the contracted bandwidth parameter may be stored in the first session management function module. When the terminal initiates a session request, the first session management function module may respond to the session request and compare the bandwidth parameter with the contracted bandwidth parameter.
[0091] In one embodiment, the second session management function module may be an SMF network element corresponding to the terminal to be responded to the session request initiated by the terminal.
[0092] Exemplarily, after the terminal initiates a session request, multiple terminals correspond to different SMF network elements respectively, and the second session management function module can be any of the SMF network elements.
[0093] In one embodiment, the second session management function module may also store bandwidth parameters and contracted bandwidth parameters of the session group.
[0094] In one embodiment, after the second session management function module receives the bandwidth data, since the number of sessions in the group changes, the bandwidth occupied by the sessions also changes, so the stored bandwidth parameters can be modified based on the bandwidth data.
[0095] In one embodiment, after modifying the bandwidth parameter, the second management function module may compare the modified bandwidth parameter with the contracted bandwidth parameter. If the modified bandwidth parameter is still not greater than the contracted bandwidth parameter, the second session management function module sends a first response signal to the first session management function module.
[0096] S230: establishing a session of the terminal upon receiving the first response signal sent by the second management function module, and modifying the bandwidth parameters stored locally based on the bandwidth data.
[0097] In one embodiment, after receiving the first response signal sent by the second session management module, the first management module determines that the session initiated by the terminal can be established, then the first session management module establishes the session and modifies the bandwidth parameters stored in the first session management module according to the bandwidth data.
[0098] The session establishment method provided by the embodiment of the present disclosure is applied to a first session management function module, and the method includes: in response to a session request sent by a terminal, obtaining a bandwidth parameter of a session group in which the terminal is located, the session request including bandwidth data required for the session, and when the bandwidth parameter is less than the contract parameter, sending the session request to a second session management function module, so that the second session management function module modifies the bandwidth parameter stored in the second management function module based on the bandwidth data, and establishing a session when a first response signal sent by the second management function module is received, wherein the first session management function module and the second session management function module both update the bandwidth parameters stored in their respective local areas based on the bandwidth data of the session, thereby avoiding the bandwidth used by the session group from exceeding the contract bandwidth, improving the communication efficiency of the session group, and improving the user experience.
[0099] Figure 3 FIG. 1 shows another flow chart of a session establishment method provided by an embodiment of the present disclosure. It should be noted that the session establishment method is applied to a first session management function module, and the first session management function module can be any module in a session management system, such as Figure 3 As shown, the session establishment method provided by the embodiment of the present disclosure may include:
[0100] S310: Receive a second modification event sent by a second session management function module.
[0101] In one embodiment, a group may include multiple session management function modules. When any other session management function module sends a session request to the second session management function module and establishes a session, the second session management function module may send a second modification event to the first session management function module to enable the first session management function module to modify the bandwidth parameters stored in the first session management function module.
[0102] S320: Modify the bandwidth parameter stored locally based on the second modification event to obtain a modified bandwidth parameter.
[0103] In one embodiment, after the first session management function module modifies the bandwidth parameters stored locally, the bandwidth parameter data stored in multiple session management function modules in the group can be made consistent.
[0104] S330, in response to a session request sent by the terminal, obtaining a bandwidth parameter of a session group in which the terminal is located, the session request including bandwidth data required for the session;
[0105] S340, when the bandwidth parameter is less than the contracted bandwidth parameter, sending a session request to the second session management function module, so that the second session management function module modifies the bandwidth parameter stored in the second management function module based on the bandwidth data;
[0106] S350: establishing a terminal session when a first response signal sent by the second management function module is received, and modifying a bandwidth parameter stored locally based on the bandwidth data.
[0107] In the session establishment method provided by the embodiment of the present disclosure, a modification event is sent to the first session management function module through the second session management function module, so that the first session management function module modifies the bandwidth parameters stored in the first session management function module, so that the data of the bandwidth parameters stored in multiple session management function modules are consistent, thereby avoiding the problem of being unable to reach a consensus on whether to establish a session due to inconsistent bandwidth parameters stored in multiple session management function modules.
[0108] Figure 4 A flow chart of another session establishment method provided by an embodiment of the present disclosure is shown. It should be noted that the session establishment method is applied to a first session management function module, and the first session management function module can be any module in the session management system, such as Figure 4 As shown, the session establishment method provided by the embodiment of the present disclosure may include:
[0109] S410: Receive a third modification event sent by the second session management function module.
[0110] In one embodiment, in one embodiment, a group may include multiple session management function modules. When any other session management function module sends a session request to the second session management function module and establishes a session, the second session management function module may send a third modification event to the first session management function module.
[0111] S420: Modify the bandwidth parameter stored locally based on the third modification event to obtain a modified bandwidth parameter.
[0112] In some embodiments, the third modification event may include bandwidth data occupied by the session established by the second session management function module.
[0113] In some embodiments, the first session management function module may modify the bandwidth parameters stored locally based on the bandwidth data.
[0114] S430: If the sum of the modified bandwidth parameter and the bandwidth data is not less than the contracted bandwidth data, cancel sending the session request to the second session management function module, and send a session establishment failure request to the terminal.
[0115] In one embodiment, the bandwidth data is bandwidth data in a session request sent by a terminal corresponding to the first session management function module.
[0116] In one embodiment, when the sum of the modified bandwidth parameter and the bandwidth parameter in the session request sent by the terminal is not less than the contracted bandwidth data, it means that the bandwidth data occupied by all sessions in the group has exceeded the contracted bandwidth data. In this case, the first session management function module determines that the session request sent by the terminal cannot be supported, and cancels sending the session request to the second session management function module, and sends a session establishment failure request to the terminal.
[0117] Figure 5 1 shows another flow chart of a session establishment method provided by an embodiment of the present disclosure. It should be noted that the session establishment method is applied to a first session management function module, and the first session management function module can be any module in a session management system, such as Figure 5 As shown, the session establishment method provided by the embodiment of the present disclosure may include:
[0118] S510, in response to a session release request sent by the terminal, the session release request including bandwidth data occupied by the session, sending the session release request to the second session management function module, so that the second session management function module modifies the bandwidth parameters stored in the second management function module based on the bandwidth data.
[0119] In one embodiment, the session release request may be a request sent by the terminal to the first session management function module when canceling the session.
[0120] In one embodiment, the second session management function module modifying the bandwidth parameter based on the bandwidth data included in the release request may include subtracting the bandwidth data included in the release request from the bandwidth parameter to obtain the modified bandwidth parameter.
[0121] S520: When a second response signal sent by the second session management function module is received, release the session.
[0122] S530: Modify the bandwidth parameters stored locally based on the bandwidth data.
[0123] In one embodiment, the method by which the first session management function module modifies the bandwidth parameters stored locally may be the same as the method by which the second session management function module modifies the bandwidth parameters, which will not be described in detail herein.

It should be noted that the session establishment method is applied to a first session management function module, and the first session management function module can be any module in a session management system, such as Figure 6 As shown, the session establishment method provided by the embodiment of the present disclosure may include:
[0125] S610: Determine a target terminal based on the modified bandwidth parameter, the subscribed bandwidth parameter, and bandwidth data required in a session request sent by a terminal that has failed to successfully establish a session in the past.
[0126] In one embodiment, after a terminal releases a session, the bandwidth parameter in the group becomes smaller, and session invitations may be sent to terminals that have not successfully established sessions in history.
[0127] In some embodiments, a threshold interval may be determined based on the difference between the modified bandwidth parameter and the contracted bandwidth parameter, and then the target terminal may be determined based on the threshold interval.
[0128] For example, if the modified bandwidth parameter is 500M and the contracted bandwidth parameter is 600M, it can be determined that the terminal initiating the session request with bandwidth data within 100M is the target terminal.
[0129] S620: Send a session invitation to the target terminal.
