[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] Optionally, as an optional implementation, as Figure 1 As shown, the group call establishment method includes:

[0031] S102, obtaining a first group call request, wherein the first group call request is a request triggered after a terminal device in an inactive state moves from a first base station to a second base station, and the terminal device in an inactive state is in a first group call when in the first base station, and the first group call request is used to request to establish a group call between the second base station and the terminal device in the inactive state;

[0032] S104, in response to the first group call request, initiating a second group call request to the first base station, wherein the second group call request is used to request the first base station to obtain group call information of the terminal device in an inactive state in the first group call;

[0033] S106: When the group call information returned by the first base station is obtained, a group call is established between the second base station and the terminal device in the inactive state according to the group call information.

[0034] In this embodiment, the above-mentioned group call establishment method can be applied to, but is not limited to, 5G broadband cluster service scenarios. In 5G broadband cluster service scenarios, after the terminal is in RRC_CONNECTED and the group call service is established in the current cell, when the terminal switches to RRC_INACTIVE and wanders outside the current cell (still in the RNA area), at this time, since the cluster core network does not perceive the terminal state (still considers the terminal to be in the RRC_CONNECTED state), the cluster core network does not establish group resources in the new cell, and the terminal will not be able to continue the cluster group call service when wandering to another cell, which will cause service interruption.

[0035] It should be noted that in the above-mentioned 5G broadband cluster service scenario, in order to take into account both power saving and service transmission requirements, a new RRC_INACTIVE (Radio Resource Control) state is added. This state has the following important features: it is transparent to the core network node, that is, AMF (Access and Mobility Management Function) is not aware; in this state, the data processing of the terminal device is suspended, but unlike the CM-IDLE state (idle state), the current base station still maintains the terminal context; when there is data transmission, it quickly switches to the RRC-Connected state. That is, in the RRC_INACTIVE state, the terminal is in a power-saving "sleeping" state, but it has to be on standby at any time, so it still retains some RAN (Radio Access Network) context (security context E capability information, etc.), always maintains connection with the network, and can quickly transfer from the RRC_INACTIVE state to the RRC_CONNECTED state through a message similar to paging, and reduce the number of signaling.

[0036] For the problem of service interruption caused by the above-mentioned, the above-mentioned group call establishment method is used. After the second base station in the new area detects a terminal device in an inactivated state based on the first group call request, it requests group call information from the first base station in the previous area of ​​the terminal device in the inactivated state, and establishes a group call between the second base station and the terminal device based on the group call information. The whole process does not require the participation of the cluster core network, nor does it require changing the state of the terminal device itself, thereby avoiding the defect of low efficiency of group call establishment caused by redundant interaction processes between the core cluster network and the terminal device, and the switching of the device's own state, and achieves the purpose of reducing the number of interactions and reducing the complexity of interaction during the group call establishment process, thereby achieving the technical effect of improving the efficiency of group call establishment and solving the problem of low efficiency of group call establishment in related systems.

[0037] Optionally, in this embodiment, the inactive state may be, but is not limited to, an RRC_INACTIVE state.

[0038] Optionally, in this embodiment, the first group call request triggered by an inactive terminal device moving from a first base station to a second base station can be understood, but not limited to, as a call service maintenance request executed by the above-mentioned terminal device during base station switching (cell switching), wherein the base station switching may not be limited to active selection by the terminal device, for example, in an area where base station signal coverage overlaps, a base station signal with a better (stronger) signal is selected to establish a group call service.

[0039] Optionally, the second base station in this embodiment needs to obtain information about the group call related group in addition to the terminal context information. After the second base station receives the first group call request initiated by the terminal device, the second base station can, but is not limited to, respond to the first group call request and initiate a second group call request to the first base station to request to obtain the terminal device matching information used to indicate the establishment of a group call between the second base station and the terminal device.

[0040] Optionally, in this embodiment, the group call information may include but is not limited to group-related information and terminal context information, wherein the group-related information may include but is not limited to group ID, group name, call type (voice group call / video group call), call attributes (emergency call indication / no right grabbing indication, etc.), audio and video media parameters, etc., and the terminal context information may include but is not limited to information on the interaction between the terminal device and the base station.

[0041] To further illustrate, an optional method for establishing a group call includes the following specific steps:

[0042] Step S202, the second base station obtains a first group call request triggered by a terminal device in an inactive state after moving from the first base station to the second base station, wherein the terminal device in an inactive state is in a first group call when in the first base station;

[0043] Step S204: The second base station responds to the first group call request and initiates a second group call request to the first base station, wherein the second group call request is used to request the first base station to obtain group call information of the terminal device in an inactive state in the first group call;

[0044] Step S206, the second base station obtains the group call information returned by the first base station;

[0045] Step S208: The second base station establishes a group call between the second base station and the terminal device in the inactive state according to the group call information.

[0046] Through the embodiments provided by the present application, after the second base station in the new area detects a terminal device in an inactivated state based on the first group call request, it requests group call information from the first base station in the previous area of ​​the terminal device in the inactivated state, and establishes a group call between the second base station and the terminal device based on the group call information. The entire process does not require the participation of the cluster core network, nor does it require changing the state of the terminal device itself, thereby avoiding the defect of low efficiency of group call establishment caused by redundant interaction processes between the core cluster network and the terminal device, and the switching of the device's own state, and achieves the purpose of reducing the number of interactions and reducing the complexity of interaction during the group call establishment process, thereby achieving the technical effect of improving the efficiency of group call establishment and solving the problem of low efficiency of group call establishment in related systems.

[0047] As an optional solution, in response to the first group call request, initiating a second group call request to the first base station includes:

[0048] S1, obtaining target identification information carried in a first group call request, wherein the target identification information is used to match group call information corresponding to the first group call;

[0049] S2: Create a second group call request based on the target identification information, and send the second group call request to the first base station.

[0050] Optionally, in this embodiment, it is possible but not limited to obtaining target identification information carried in the first group call request, wherein the target identification information may be but not limited to being used to match corresponding group call information, and the target identification information may be but not limited to including first identification information for matching group-related information of the group call between the terminal device and the first base station, and second identification information for matching terminal context information of the terminal device.

[0051] It should be noted that after the second base station obtains the target identification information carried in the first group call request, it creates a second group call request for requesting the first base station for group call information based on the target identification information.

[0052] Through the embodiment provided in the present application, the target identification information carried in the first group call request is obtained, wherein the target identification information is used to match the group call information corresponding to the first group call; a second group call request is created based on the target identification information, and the second group call request is sent to the first base station.

[0053] As an optional solution, obtaining the target identification information carried in the first group call request includes:

[0054] S1, obtaining first identification information and second identification information included in target identification information;

[0055] Acquiring the group call information returned by the first base station, including:

[0057] Optionally, in this embodiment, the target identification information may include but is not limited to first identification information and second identification information, wherein the first identification information may be but is not limited to being used to match group-related information, the group-related information may be but is not limited to related group service information for a group call established between the terminal device and the first base station, and may include but is not limited to group ID, group name, call type (voice group call / video group call), call attributes (emergency call indication / no right grabbing indication, etc.), audio and video media parameters, etc.; the second identification information may be but is not limited to being used to match terminal context information.

[0058] It should be noted that the terminal context information can be but is not limited to being used to indicate the configuration information of the terminal device itself when establishing a group call connection between the terminal device and the base station, and the group-related information can be but is not limited to being used to indicate the service information of the group call in the corresponding area, such as service priority, service members and other information.

[0059] It should be noted that when the terminal device is in the RRC_INACTIVE state and moves to a new cell, the terminal device notifies the second base station corresponding to the new cell through the first group call request. The first group call request carries the group call ID and the expansion identifier, and obtains the context information of the terminal device from the first base station served last time, and also obtains the group call related information.

[0060] Through the embodiment provided by the present application, the target identification information carried in the first group call request is obtained, including: obtaining the first identification information and the second identification information included in the target identification information; obtaining the group call information returned by the first base station, including: obtaining the group related information matched with the first identification information returned by the first base station, and the terminal context information matched with the second identification information. The new base station obtains the corresponding group call related information and terminal context information from the old base station that was served last time through the first identification information and the second identification information included in the target identification, and can not only obtain the context information of the terminal itself, but also obtain the group call related information on the service, thereby achieving the purpose of improving the comprehensiveness of the acquisition of group call information, thereby avoiding additional operations in the process of establishing a group call between the terminal device and the second base station and the subsequent group call service, and improving the efficiency of group call establishment.

[0061] As an optional solution, obtaining the group related information returned by the first base station and matching the first identification information includes:

[0062] S1, obtaining a plurality of group-related sub-information corresponding to a plurality of group ID information included in the first identification information and returned by the first base station, wherein each of the plurality of group-related sub-information has a different type, and the group-related information includes a plurality of group-related sub-information.

[0063] Optionally, in this embodiment, the first identification information may, but is not limited to, carry multiple group ID information, wherein each group ID information may, but is not limited to, correspond to each type of group-related sub-information, and may, but is not limited to, correspond to the following types of group-related sub-information: group name, call type (voice group call / video group call), call attributes (emergency call indication / no right grabbing indication, etc.), audio and video media parameters, etc.

[0064] Optionally, in this embodiment, after acquiring each type of group-related sub-information corresponding to each group ID information, group-related information matching the first identification information is generated.

[0065] To further illustrate, Figure 3 As shown, a method for determining group call information based on the above group call establishment method includes:

[0066] Step S1, obtaining a first group call request 302;

[0067] Step S2, obtaining the target identification information 304 carried in the first group call request 302, wherein the target identification information 304 includes the first identification information 306 and the second identification information 308;

[0071] Through the embodiment provided by the present application, multiple group-related sub-information corresponding to multiple group ID information included in the first identification information returned by the first base station is obtained, wherein the types of each of the multiple group-related sub-information are different, and the group-related information includes multiple group-related sub-information. The purpose of improving the comprehensiveness of obtaining group call information is achieved, thereby avoiding additional operations in the process of establishing a group call between a terminal device and a second base station and subsequent group call services, and improving the efficiency of establishing a group call.

[0072] As an optional solution, after establishing a group call between the second base station and the terminal device in an inactive state by using the group call information, the method further includes:

[0073] S1, initiating a third group call request to the cluster core network, wherein the third group call request is used to request to establish a transmission connection between the second base station and the cluster core network;

[0074] S2: after the transmission connection is established, synchronize the group call related information to the cluster core network.

[0075] Optionally, in this embodiment, after the second base station establishes a group call with the terminal device using the group call information obtained from the first base station, the second base station may, but is not limited to, initiate a third group call request to the cluster core network to request establishment of a transmission connection.

[0076] Optionally, in this embodiment, after the transmission connection is established, the second base station may, but is not limited to, synchronize group call-associated information to the cluster core network, wherein the group call-associated information may, but is not limited to, include connection information of the group call between the terminal device and the second base station, and may also, but is not limited to, include service record information of the group call between the terminal device and the second base station in a target time period, wherein the target time period may, but is not limited to, be a periodic time period.

[0077] It should be noted that the cluster core network itself does not participate in the process of establishing a group call between the terminal device and the base station, but after the group call is established, it synchronizes and backs up relevant data information as a notified object.

[0078] Through the embodiment provided by the present application, a third group call request is initiated to the cluster core network, wherein the third group call request is used to request the establishment of a transmission connection between the second base station and the cluster core network; after the transmission connection is established, the group call-related information is synchronized to the cluster core network.

[0079] As an optional solution, after initiating the third group call request to the cluster core network, the method further includes:

[0080] S1, obtaining a negotiation result returned by the cluster core network in response to the third group call request, wherein the negotiation result is used to indicate configuration information of the transmission connection;

[0083] Through the embodiment provided by the present application, the negotiation result returned by the cluster core network in response to the third group call request is obtained, wherein the negotiation result is used to indicate the configuration information of the transmission connection; based on the configuration information, the transmission connection is established. After the group call is established, the synchronization and backup of the group call related information are realized through the transmission connection between the second base station and the cluster core network, so as to achieve the purpose of reverse negotiation of the group call related information between the base station and the cluster core network, thereby improving the overall efficiency of the group call establishment.

[0084] As an optional solution, after obtaining the first group call request, the method further includes:

[0085] S1, in response to the first group call request, initiating a fourth group call request to the cluster core network, wherein the fourth group call request is used to request the cluster core network to obtain group call information of the terminal device in an inactive state in the first group call;

[0086] S2: When the group call information returned by the cluster core network is obtained, a group call is established between the second base station and the terminal device in an inactive state according to the group call information.

[0087] Optionally, in this embodiment, the cluster core network may be used, but is not limited to, to send the acquired group call information of the terminal device in the inactive state in the first group call.

[0088] Optionally, in this embodiment, when the group call information returned by the cluster core network is acquired, a group call is established between the second base station and the terminal device in the inactive state according to the group call information.

[0089] It should be noted that, in this embodiment, unlike the above-mentioned acquisition of context information and group information from the first base station, in this embodiment, the first base station acquires context information and acquires group call information (including group information) from the core cluster network.

[0090] As an optional solution, before initiating the fourth group call request to the cluster core network, the method further includes:

[0091] S1, obtaining target identification information carried in the first group call request, wherein the target identification information is used to match terminal context information corresponding to the first group call;

[0092] S2, creating a second group call request based on the target identification information, and sending the second group call request to the first base station;

[0093] S3: Obtain terminal context information returned by the first base station.

[0094] Optionally, in this embodiment, before initiating a fourth group call request to the cluster core network, the target identification information carried in the first group call request is obtained, wherein the target identification information is used to match the terminal context information corresponding to the first group call, and may include but is not limited to expansion identification information and group ID information.

[0095] Optionally, in this embodiment, a second group call request is created based on the target identification information, and the second group call request is sent to the first base station, and the terminal context information returned by the first base station in response to the second group call request is obtained.

[0096] As an optional solution, using the group call information to establish a group call between the second base station and the terminal device in an inactive state includes:

[0097] S1, sending a first group call request to a terminal device in an inactive state, wherein the terminal device in an inactive state maintains the inactive state after receiving the first group call request, and establishes a group call with a second base station.

[0098] Optionally, in this embodiment, during the process of the terminal device and the second base station establishing a group call based on the group call information, the terminal device may, but is not limited to, maintain an inactive state by itself, wherein the inactive state may, but is not limited to, be an RRC_INACTIVE state.

[0099] Through the embodiments provided in the present application, in the process of establishing a group call connection, the terminal device does not need to change its own inactive state, and does not need to switch from the RRC_INACTIVE state to the RRC_CONNECTED state, thereby achieving the purpose of reducing process overhead and maintaining power saving, thereby achieving the technical effect of improving the efficiency of group call establishment.

[0100] As an optional solution, the above-mentioned group call establishment method is applied to an application scenario of controlling the continuity of cluster group calls between base stations. When the terminal is in the RRC_INACTIVE state and moves to a new cell, the terminal notifies the cluster base station through the RRCResumeRequest message, carrying the group call ID and the expansion identifier. The cluster base station obtains the context information of the terminal from the last served cluster base station, and also obtains the group call related information. The cluster base station notifies the terminal to remain in the RRC_INACTIVE state, and directly initiates the group call expansion process based on the obtained group call information to ensure that the terminal receives the group call in the new cell as soon as possible. Then the cluster base station actively synchronizes the group call expansion information with the cluster core network, and reversely negotiates the context and transmission bearer information.

[0101] As an alternative, Figure 4 As shown, an optional method for establishing a group call includes the following specific steps:

[0102] Step S402, the second base station obtains a first group call request initiated by a terminal device in an inactive state;

[0103] Step S404: The second base station responds to the first group call request and initiates a second group call request to the first base station;

[0104] Step S406, the second base station obtains the group call information returned by the first base station;

[0105] Step S408, the second base station uses the group call information to establish a group call between the second base station and the terminal device;

[0106] Step S410: The second base station obtains a fifth group call request initiated by the third base station, wherein the fifth group call request is used to request an instruction to establish a group call between the third base station and a terminal device in an inactive state;

[0107] Step S412: The second base station responds to the fourth group call request and returns target group call information to the third base station, wherein the target group call information may be determined based on, but is not limited to, the group call information.

[0108] Through the embodiment provided by the present application, the fifth group call request triggered by the third base station is obtained, wherein the fifth group call request is used to request to obtain the target group call information, and the target group call information is used to indicate the establishment of a target group call between the third base station and the terminal device in an inactive state; in response to the fifth group call request, the target group call information is returned to the third base station. The base station in each area can both initiate a request to obtain group call information and respond to requests initiated by other base stations to return target group call information, thereby achieving a continuous group call establishment process between base stations, without the participation of the cluster core network, avoiding unnecessary redundant interaction processes, and quickly establishing group call resources, thereby achieving the technical effect of improving the efficiency of group call establishment.

[0109] As an optional solution, the above-mentioned group call establishment method is applied to an application scenario of controlling the continuity of cluster group calls between base stations. When the terminal is in the RRC_INACTIVE state and moves to a new cell, the terminal notifies the cluster base station through the RRCResumeRequest message, carrying the group call ID and the expansion identifier. The cluster base station obtains the context information of the terminal from the last served cluster base station, and also obtains the group call related information. The cluster base station notifies the terminal to remain in the RRC_INACTIVE state, and directly initiates the group call expansion process based on the obtained group call information to ensure that the terminal receives the group call in the new cell as soon as possible. Then the cluster base station actively synchronizes the group call expansion information with the cluster core network, and reversely negotiates the context and transmission bearer information.

[0110] To further illustrate, a complete business description such as Figure 5 As shown, the specific steps include:

[0111] Step S502, the terminal is in RRC_CONNECTED state, and a group call is in progress;

[0112] Step S504, the terminal is in the RRC_INACTIVE state and moves to a new base station, and no group call resources have been established under the new base station;

[0113] Step S506: The terminal sends a RRCResumeRequest message to the current base station (new base station), carrying the expansion identifier and group ID information;

[0114] Step S508, the current base station receives the request from the terminal, and sends a Retrieve UEContext Request message to the previous serving base station to request to obtain the terminal context information, and at the same time carries a request to obtain the group call related information;

[0115] Step S510: the previous serving base station sends a Retrieve UE Context Response to return the terminal context information and group call related information;

[0116] Step S512, the cluster base station sends a RRCResume message to notify the terminal to remain in the RRC_INACTIVE state;

[0117] Step S514, the terminal remains in the RRC_INACTIVE state;

[0118] Step S516, the current base station initiates a group call expansion process in the cell according to the acquired group call information (including terminal context information and group call related information);

[0119] Step S518: the current base station notifies the cluster core network that a group call expansion has been carried out in the new cell, and establishes a connection context (connection information indicating a connection channel) and negotiates transmission bearer (transmission information indicating a connection channel) and other parameters with the cluster core network;

[0120] Step S520: the cluster core network responds to the request and completes the negotiation and establishment of the connection context and transport bearer.

[0121] It should be noted that the above group call establishment method can at least achieve the following beneficial effects:

[0122] (1) Adding new service processes to ensure service continuity of terminals in the RRC_INACTIVE state;

[0123] (2) The terminal does not need to enter the RRC_CONNECTED state, reducing process overhead and maintaining power saving;

[0124] (3) Base stations obtain information and initiate the group call expansion process, reducing interactions and quickly establishing group call resources;

[0125] (4) Reverse negotiation between the base station and the cluster core network to establish a group call context;

[0126] (5) Solve the problem of continuous group call service when the terminal is in the RRC_INACTIVE state, meet the application of relevant business scenarios, and improve user experience.

[0130] Step S608 : When the server 612 obtains the group call information, it uses the group call information to establish a group call between the second base station and the user equipment 602 .
