Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
As described in the background art, in the related art, when a mobile terminal moves to an underground garage, an elevator, or the like without a signal coverage area, the mobile terminal cannot interact with a network for signaling and data, and if a 5G MBS session exists in the mobile terminal, a 5G MBS (multicast-broadcast service under 5G system) application of the mobile terminal cannot receive 5G MBS data. When the mobile terminal moves from the area without signal coverage to the area with signal coverage again, the mobile terminal initiates a mobility registration procedure, and then the UE (mobile terminal) and the network resume normal communication.
Fig. 1 is a schematic flow chart of an exemplary procedure for paging a mobile terminal by a network end using a TMGI in the related art.
Through studies by the inventor, referring to fig. 1, in this process, when the mobile terminal moves to an area with signal coverage again, the mobile terminal initiates a mobility registration procedure, sends a mobility registration request to a network end, and carries therein a protocol data unit session ID (i.e., PDU session ID) used by the mobile terminal in an active state. However, when the terminal locally exits the 5G MBS, the current PDU session (i.e., the protocol data unit session) still exists, and is not released, but the 5G MBS QoS flow (i.e., the quality of service flow corresponding to the 5G multicast-broadcast service) of the PDU session is released.
And the network does not know that the mobile terminal exits the 5G MBS locally, so that the 5G MBS is still used for the terminal, and meanwhile, the network discovers that the link for transmitting the 5G MBS service to the mobile terminal is disconnected, and triggers a paging procedure, sends paging information (namely paging information) to the mobile terminal, carries TMGI information (namely temporary mobile group identification information) and tries to recover the 5G MBS service. The mobile terminal will not reply to the paging information of the network because it has exited the 5G MBS service, and the network will periodically continue to send the paging information to the mobile terminal. That is, when the mobile terminal initiates the mobility registration process, the network side is informed of whether the PDU session corresponding to the 5G MBS is active or not, and the network side cannot perceive that the mobile terminal has locally released the 5G MBS QoS flow in the PDU session. The network can periodically send paging to the mobile terminal and carry TMGI information, so that the power consumption of the mobile terminal is increased and the waste of air interface resources is also caused.
As such, the present application provides a session interaction method, apparatus, system, device, storage medium and program product, applied to a mobile terminal, for sending a session joining request to a network end; in response to receiving a request acceptance response from the network side, at least one target quality of service flow is newly established in a target protocol data unit session in the network side to establish a data radio bearer, and a target multicast-broadcast service is activated according to the data radio bearer; the request acceptance response is used for indicating that the session joining request is accepted by the network side; responding to the disconnection of the mobile terminal and the network end, closing the target multicast-broadcast service, and carrying out corresponding processing operation on all service quality flows in the target protocol data unit session; sending a mobility registration request to the network side; and in response to receiving a mobility registration success response from the network side, completing the mobility registration request to enable the mobile terminal to resume communication with the network side. According to the method and the device, through carrying out corresponding processing operation on all service quality flows in the target protocol data unit session, resources related to the target multicast-broadcast service are released, so that when a network end cannot analyze a flow ID corresponding to the target multicast-broadcast service, the network end does not use TMGI to page the mobile terminal, power consumption of the mobile terminal and the network end is reduced, and air interface resources are saved.
In some specific application scenarios, the session interaction method can be applied to various systems related to session interaction, and the systems can be operated through a PC end or a mobile end such as a mobile phone or a tablet computer.
In some specific application scenarios, the session interaction method of the application can be directly applied to local operation or can be operated in a cloud server. When the cloud server runs, the acquired data to be processed is sent to the cloud server through a network, the server processes the data to be processed through the session interaction method, and the processing result is sent to the local through the network.
The session interaction method according to the exemplary embodiments of the present application is described below in connection with a specific application scenario. It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present application, and embodiments of the present application are not limited in any way in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.
The session interaction method provided by the embodiment of the application is specifically described by a specific embodiment.
Fig. 2 is a schematic flow chart of an exemplary session interaction method applied to a mobile terminal according to an embodiment of the present application.
Referring to fig. 2, the session interaction method provided in the embodiment of the present application is applied to a mobile terminal, and the method specifically includes the following steps:
s202: and sending a session joining request to the network side.
S204: in response to receiving a request acceptance response from the network side, at least one target quality of service flow is newly established in a target protocol data unit session in the network side to establish a data radio bearer, and a target multicast-broadcast service is activated according to the data radio bearer; the request acceptance response is used for indicating that the session joining request is accepted by the network side.
S206: and responding to the disconnection of the communication between the mobile terminal and the network end and closing the target multicast-broadcast service, and carrying out corresponding processing operation on all the service quality flows in the target protocol data unit session.
S208: and sending a mobility registration request to the network side.
S210: and in response to receiving a mobility registration success response from the network side, completing the mobility registration request to enable the mobile terminal to resume communication with the network side.
In some embodiments, when the mobile terminal wants to receive MBS multicast or broadcast, the mobile terminal may send an application for joining an MBS session, that is, a session joining request, to the network, and wait for the network to reply to the mobile terminal with the result of the application, including a request to accept a response or a request to reject a response. If the network accepts the session joining application, the network instructs the mobile terminal to newly establish a QoS Flow (QoS Flow ID) in the network end to establish a DRB using the QoS Flow (Data Radio Bearers, data radio bearer). The mobile terminal and the network can perform target multicast-broadcast service data transceiving through the DRB, namely the mobile terminal can activate target multicast-broadcast service through the DRB, for example, the target multicast-broadcast service can be 5G MBS service.
It should be noted that, when the mobile terminal no longer uses MBS multicast or broadcast, an application for MBS session departure may be sent to the network, and the network waits for the network to reply the result of the application to the mobile terminal: request grant response or request rejection response. Or the network initiates a command for the MBS session to leave to the mobile terminal, and if the command is received by the mobile terminal, the mobile terminal ends the target multicast-broadcast service. The method for the mobile terminal to use the 5G MBS service includes two methods, assuming that the target multicast-broadcast service is the 5G MBS: MBS based on SIB messages and MBS based on PDU session.
In some embodiments, there are two ways for a mobile terminal to join a session corresponding to a target multicast-broadcast service. One may create a target pdu session so that the target pdu session can carry the session corresponding to the target multicast-broadcast service. Another is that the PDU session that is currently already present can be multiplexed. And creating a QoS flow on the current PDU session for bearing the session corresponding to the target multicast-broadcast service. The original data service on the PUD session is continuously transmitted through the original QoS flow, and the original data service and the original QoS flow are not mutually interfered.
Specifically, at least one target qos flow may be newly established in a target pdu session in the network side to establish a data radio bearer, and a target multicast-broadcast service is activated according to the data radio bearer.
Further, when the mobile terminal joins the session corresponding to the target multicast-broadcast service by newly creating a target protocol data unit session, it requests the network to release the PDU session by triggering PDU SESSION RELEASE procedure (i.e. protocol data unit session release procedure) when it leaves the session corresponding to the target multicast-broadcast service, so that the mobile terminal leaves the session corresponding to the target multicast-broadcast service.
In some embodiments, when the mobile terminal joins the session corresponding to the target multicast-broadcast service by multiplexing the PDU session that is currently already present, a PDU SESSION MODIFICATION procedure may be triggered to request the network to release the QoS flow of the target multicast-broadcast service in the PDU session, so that the mobile terminal leaves the session corresponding to the target multicast-broadcast service. In particular, a session modification request may be sent to the network side to request the network side to release all target quality of service flows in the target protocol data unit session, so that the mobile terminal turns off the target multicast-broadcast service.
In some embodiments, the mobile terminal disconnects from the network, for example, when the mobile terminal moves to an underground garage, an elevator, or the like without signal coverage area, the mobile terminal cannot interact with the network for signaling and data, and if the mobile terminal has a 5G MBS session, the 5GMBS application of the mobile terminal cannot receive the 5G MBS data. And when the mobile terminal closes the target multicast-broadcast service, the resources corresponding to all the target service quality flows in the mobile terminal can be released, the resources corresponding to other service quality flows except the target service quality flows are reserved, and the temporary mobile group identifier corresponding to the target multicast-broadcast service is deleted. Compared with the method in the related art that the current PDU session is still existing and not released when the terminal locally exits the 5GMBS, but the 5G MBS QoS flow method of the PDU session is released, the power consumption of the mobile terminal can be reduced, and air interface resources can be saved.
In some embodiments, when the mobile terminal moves to the area with signal coverage again, in order to solve the problem of mismatch of service states between the mobile terminal and the network during a short network drop period, it is specified in the current 3GPP protocol that, when the mobile terminal initiates a mobility registration procedure, the network is notified of the PDU session ID of the PDU session currently in an active state by the mobile terminal, so as to achieve the match of service states between the mobile terminal and the network.
Further, the application determines a target session ID corresponding to the target protocol data unit session and a flow ID corresponding to other qos flows except the target qos flow in the target protocol data unit session; wherein the target session ID is associated with a flow ID corresponding to a target quality of service flow and a flow ID corresponding to other quality of service flows except the target quality of service flow, respectively. Still further, the target session ID and flow IDs corresponding to other qos flows in the target pdu session than the target qos flow are added to the mobility registration request. The mobile terminal initiates mobile registration, and carries the target session ID corresponding to the target protocol data unit session and the stream IDs corresponding to other service quality streams except the target service quality stream in the target protocol data unit session.
Still further, when a mobility registration success response is received from the network side, the mobility registration request is completed to enable the mobile terminal to resume communication with the network side.
Fig. 3 is an exemplary flowchart of a session interaction method applied to a network side according to an embodiment of the present application.
Referring to fig. 3, a session interaction method provided by an embodiment of the present application is applied to a network, and the method specifically includes the following steps:
s302: in response to receiving a session join request from a mobile terminal, determining whether to accept the session join request to enable the mobile terminal to establish communication with the network side.
S304: and in response to receiving the session joining request, sending a request accepting response to the mobile terminal, and indicating the mobile terminal to newly establish at least one target quality of service flow in a target protocol data unit session to establish a data radio bearer, so that the mobile terminal activates a target multicast-broadcast service according to the data radio bearer.
S306: and responding to the received mobility registration request from the mobile terminal, and analyzing the mobility registration request to determine a flow ID set corresponding to all current service quality flows in the protocol data unit session.
S308: and determining whether a stream ID corresponding to the target quality of service stream exists in the stream ID set.
S310: and in response to determining that the stream IDs corresponding to the target service quality streams do not exist in the stream ID set, performing corresponding processing operation on all the target service quality streams, and sending a registration success response to the mobile terminal to indicate the mobile terminal to resume communication with the network side.
In some embodiments, when the network receives a session join request from the mobile terminal, the network may choose to accept or reject, and when accepting its session join request, the network may send a request accept response to the mobile terminal, thereby indicating that the mobile terminal may newly establish at least one target quality of service flow in a target protocol data unit session to establish a data radio bearer, so that the mobile terminal activates a target multicast-broadcast service according to the data radio bearer. That is, any currently existing protocol data unit session is multiplexed as a target protocol data unit session, and at least one target quality of service stream is newly established therein to establish a data radio bearer, so that the mobile terminal activates a target multicast-broadcast service according to the data radio bearer.
In some embodiments, the network receives a mobility registration request from a mobile terminal, comprising: a mobility registration request comprising: and the target session ID corresponding to the target protocol data unit session and the stream IDs corresponding to other service quality streams except the target service quality stream in the target protocol data unit session. Therefore, the target session ID corresponding to the target protocol data unit session carried in the mobility registration request can be resolved, the target protocol data unit session is determined according to the target session ID, and the set of stream IDs corresponding to all the current quality of service streams in the target protocol data unit session is determined.
Further, it may be determined whether a flow ID corresponding to the target qos flow exists in the flow ID set, and if it is determined that a flow ID corresponding to the target qos flow does not exist in the flow ID set, a corresponding processing operation may be performed on all the target qos flows. Specifically, resources corresponding to all target qos flows in the network may be released, and temporary mobile group identifiers corresponding to the target multicast-broadcast services may be deleted.
When the network determines that the Flow ID corresponding to the target quality of service Flow does not exist in the Flow ID set, the network considers that the target multicast-broadcast service session of the mobile terminal does not exist, and can release the QoS Flow resource related to the target multicast-broadcast service session of the network side, and the network does not use the TMGI to page the mobile terminal.
Compared with the related art, the network does not know that the mobile terminal locally exits the target multicast-broadcast service session, so that the target multicast-broadcast service session is still used for the terminal, meanwhile, the network finds that the link for transmitting MBS service to the mobile terminal is disconnected, and triggers a paging process, and sends a paging message to the mobile terminal, carries TMGI information, and tries to recover the target multicast-broadcast service.
In some embodiments, the mobile terminal may actively apply for exiting the target multicast-broadcast service, and when the network receives a session modification request from the mobile terminal, the mobile terminal releases all target qos flows in the target pdu session to shut down the target multicast-broadcast service in the mobile terminal, unlike a short drop scenario.
Fig. 4 shows an exemplary flow diagram of a specific implementation of a session interaction method according to an embodiment of the present application.
Referring to fig. 4, taking a target multicast-broadcast service as a 5G MBS as an example, a mobile terminal may activate the 5G MBS service by multiplexing a PDU session that is already present, for example, changing the PDU session that is already present, creating at least one target quality of service flow therein to establish a data radio bearer, and activating the 5G MBS service according to the data radio bearer.
Further, when the mobile terminal with 5G MBS service enters the area without signal coverage and the user closes the 5G MBS application, the mobile terminal locally releases the QoS Flow resource related to the 5G MBS session and reserves other QoS Flow resources unrelated to the 5G MBS session. I.e. releasing the resources corresponding to all the target qos flows in the mobile terminal, reserving the resources corresponding to other qos flows except the target qos flows, and deleting the temporary mobile group identifier corresponding to the target multicast-broadcast service.
Still further, after the mobile terminal moves to the area with signal coverage again, the mobile terminal initiates mobility registration to the network, and the registration request includes the PDU session activated QoS Flow ID (QoS Flow identifier) in addition to the PDU session ID, and does not include the QoS Flow ID used by the released 5G MBS session. I.e. mobility registration request, comprising: and the target session ID corresponding to the target protocol data unit session and the stream IDs corresponding to other service quality streams except the target service quality stream in the target protocol data unit session.
After the network receives the mobility registration request, the network analyzes the QoS Flow ID currently existing in the PDU session used by the 5G MBS, and when the network confirms that the QoS Flow for the 5G MBS session does not exist, the network considers that the 5G MBS session at the mobile terminal side does not exist, so that QoS Flow resources related to the 5G MBS session in the network can be released, and the network does not use TMGI to page the mobile terminal. That is, the target session ID corresponding to the target protocol data unit session carried in the mobility registration request is resolved, the target protocol data unit session is determined according to the target session ID, and the set of stream IDs corresponding to all current quality of service streams in the target protocol data unit session is determined. And if the stream IDs corresponding to the target service quality streams do not exist in the stream ID set, carrying out corresponding processing operation on all the target service quality streams, and sending a registration success response to the mobile terminal to indicate the mobile terminal to resume communication with the network side.
It should be noted that, the QoS Flow ID carried by the mobility registration request is associated with PDU session, i.e. 1 or more QoS Flow IDs are associated with 1 PDU session ID; if there are multiple PDU session IDs, then each PDU session ID needs to be associated with a respective 1 or more QoS Flow IDs. And the network end releases QoS Flow resources related to the 5G MBS session, and the network does not use TMGI to page the mobile terminal any more, thereby saving signaling overhead of the network end.
For other service scenes of the mobile terminal which are not 5G MBS service, the service is required to be terminated when the mobile terminal enters a non-service scene, and the PDU session has N QoS flows, but the service uses less than N QoS flows, and the application is also applicable when the mobile terminal reenters a service area to initiate mobile registration. That is, after receiving the registration request, the network analyzes the QoS Flow ID existing in the PDU session, and for the QoS Flow ID that does not exist, releases the corresponding DRB, so as to save air interface resources.
From the above, it can be seen that the session interaction method, apparatus, system, device, storage medium and program product provided in the present application are applied to a mobile terminal, and send a session joining request to a network end; in response to receiving a request acceptance response from the network side, at least one target quality of service flow is newly established in a target protocol data unit session in the network side to establish a data radio bearer, and a target multicast-broadcast service is activated according to the data radio bearer; the request acceptance response is used for indicating that the session joining request is accepted by the network side; responding to the disconnection of the mobile terminal and the network end, closing the target multicast-broadcast service, and carrying out corresponding processing operation on all service quality flows in the target protocol data unit session; sending a mobility registration request to the network side; and in response to receiving a mobility registration success response from the network side, completing the mobility registration request to enable the mobile terminal to resume communication with the network side. According to the method and the device, through carrying out corresponding processing operation on all service quality flows in the target protocol data unit session, resources related to the target multicast-broadcast service are released, so that when a network end cannot analyze a flow ID corresponding to the target multicast-broadcast service, the network end does not use TMGI to page the mobile terminal, power consumption of the mobile terminal and the network end is reduced, and air interface resources are saved.

The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices.
