Detailed Description
A Long Term Evolution (LTE) system is mainly applicable to point-to-point communication, i.e., one user communicates with another user through a network, but does not support a function of sending voice or data to multiple users at the same time. In order to support such functions, the industry alliance of the LTE Broadband cluster (B-TrunC) is established in China, and is responsible for the standard formulation and industry development planning of the Broadband cluster. The LTE broadband cluster supports services such as broadband data, voice cluster and multimedia cluster scheduling, can support the establishment of a group, and can realize that a certain UE in the group can simultaneously send voice and data to other UEs in the group. Each UE may know to which group it belongs, or to which groups, and since the UEs may be mobile, UEs within the same group may be distributed over different cells of different cluster base stations.
Currently, a group call may be initiated by a dispatch station or a user within a group, and the network allows the group call to be established. When a group call is established, the UE of the group, whether in an idle state or a connected state, may receive the group call and obtain corresponding NAS signaling and data.
However, if the group call is established by the above method, the network side cannot know whether the UE in the group is participating in the group call communication.
In order to solve the above problems, embodiments of the present invention provide a group call establishment method, in which a cluster core network device receives group call establishment request information from a group call initiator, and sends indication information representing that a group call state needs to be fed back in the group call establishment request information to a user equipment through a cluster base station, and when the user equipment receives the indication information, feeds back information representing that the user equipment is receiving the group call to a cluster core network side, so that the network side can know the user equipment participating in the group call communication.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The following shows a signaling interaction diagram of a system for establishing a group call in the embodiment of the present invention, as shown in fig. 1, the system is adapted to establish a group in a broadband trunking network, where the group includes n user equipments, n is an integer and n > 1, the system may include a user equipment 11 (which may be UE1 … UEn in sequence), a trunking base station 12, a trunking core network equipment 13, and a group call initiator 14, and the following describes a flow of establishing a group call in detail with reference to fig. 1:
s11: the group call initiator 14 sends group call setup request information to the cluster core network device 13.
In specific implementation, when a group in a trunking communication network needs to be established, the group call initiator 14 may send group call establishment request information to the trunking core network device 13, and in the group call establishment request information, indication information representing that a group call state needs to be fed back is carried, so that some user devices 11 may feed back a state in which they receive the group call.
It will be appreciated that the user device 11 may be a member of a group in a broadband trunked network.
In a specific implementation, the group call initiator 14 may be of various types, for example, may be a scheduling management device, and may also be any one of the n user devices 11.
In an embodiment of the present invention, the group call initiator 14 is a scheduling management device, the group call establishment request message may be Session Initiation Protocol (SIP) (INVITE), and the group call establishment request message further carries a service identifier pttcall, a call type call, a call priority attribute identifier (PrioAttribute), an end-to-end encryption indicator e2ee, and a simplex-duplex indicator duplex.
In another embodiment of the present invention, the group Call initiator 14 is one of the n user equipments 11, the group Call setup Request message may be Trunking Service Request message (NAS signaling), where in addition to the security information, the group Call setup Request message also carries a Call Request message (the message carries a Call type (group Call), a Call attribute, a called number (called group identifier), media information, and the like) for applying for setting up a Trunking group Call Service, and the Call Request message may also carry identity information of a group member that needs to feed back the situation of receiving the group Call when indicating the group Call, that is, the user equipment 11 in the group. It should be noted that, when the group call initiator 14 is one of the user equipments 11, for example, UE23, the UE23 is located at the position of the group call initiator 14 in the signaling interaction diagram, that is, it interacts with other equipments and other user equipments in the group except for itself according to the identity of the group call initiator described in this embodiment.
In an embodiment of the present invention, the indication information indicating that the group call state needs to be fed back may be identification information of the user equipment 11, where the user equipment 11 is the user equipment 11 that needs to feed back information indicating that the user equipment itself is receiving the group call. For example, the user equipment 11 included in the group is UE1, UE2 … UEn, and the user equipment 11 that needs to feed back the group call receiving status is UE1, UE2, and UE3, the indication information indicating that the group call receiving status needs to be fed back may be the identity information of UE1, UE2, and UE 3. It should be noted that the identification information of the user equipment 11 may be a permanent identity of the user equipment 11, a temporarily assigned identity, or a random number, as long as a specific user equipment 11 can be identified. And the number of the user equipments 11 that need to feed back their own receiving group call state may be one or more, and the number does not limit the protection scope of the present invention.
S12: the trunking core network equipment 13 replies a SIP (100Trying) message to the group call initiator 14.
In a specific implementation, if the group call initiator 14 is any user equipment 11 in the group, before performing step S12, the cluster core network device 13 and the scheduling management device may determine whether to allow the group call to be established, and if so, may perform step S12; if the group call initiator 14 is a dispatch management device, it may reply to the dispatch management device with a SIP (100Trying) message directly to inform the dispatch management device that its request is being processed.
S13: the cluster core network device 13 sends a group paging command to the cluster base station 12.
In specific implementation, when the trunking core network device 13 may send a group paging command to the trunking base station 12, the group paging command carries user identification information that needs to feed back a group call receiving state of the user.
And because some user equipments 11 are in the coverage area of the cell served by a certain cluster base station 12, and some other user equipments 11 may not be in the coverage area of the cell served by the cluster base station 12, in an embodiment of the present invention, in order to save communication resources and improve the rate of group call establishment and communication, the cluster core network equipment 13 may determine the user equipment 11 that any one cluster base station 12 may cover according to the location information provided when the user equipment 11 in the group is registered, and then when sending a group paging command to the certain cluster base station 12, only needs to carry the identity identification information of some user equipments 11 in the coverage area of the cluster base station 12. For example, the UE2 and the UE3 in the user equipment 11 are within the coverage of the cell under the jurisdiction of a certain cluster base station 12A, although the user equipment 11 that needs to feed back the group call state received by itself is UE1, UE2, and UE3, the group paging command sent to the certain cluster base station 12A only includes the identity information of UE2 and UE 3.
S14: the Trunking base station 12 broadcasts Trunking Paging signaling (Trunking Paging) over the air interface.
In a specific implementation, when receiving a group Paging command from the Trunking core network device 13, the Trunking base station 12 may broadcast a Trunking Paging signaling (Trunking Paging) over an air interface of a cell under the jurisdiction, where the Trunking Paging signaling carries identity information of the user equipment 11 that needs to feed back a situation of receiving the group call, and the identity information may include, for example, UE2 and UE 3. That is, the members in the group, i.e. the user equipments, do not necessarily have to be the same as the cell or the cluster base station, and each cluster base station broadcasts signaling to the cells and the user equipments within its jurisdiction.
The Trunking paging signaling also carries a Trunking Group ID (Group identifier), a Group priority, and a radio network temporary identifier of a Group; optionally, the static resource list and NAS message may be carried, where the static resource list and NAS message include GROUP CALL SETUP identity information (GROUP CALL SETUP identity), and the NAS GROUP CALL SETUP information may carry one or more of the following information: call identification (Call ID), Call Type (Call Type), Media Type (Media Type), Service Type (Service Type), Call Attribute (Call Attribute), Number of Call (Called Number), and Description of Media (Media Description). If the static resource list and the NAS message GROUP call INDICATION are carried, the user equipment 11 in the GROUP may directly configure a TTCH (Trunking Traffic Channel) after receiving the Trunking paging signaling, and start receiving the service data.
S15: the cluster core network device 13 initiates a group context setup procedure message.
In a specific implementation, the cluster core network device 13 may initiate a group context setup procedure message to the cluster base station 12 to notify the cluster base station 12 to setup a cluster group call service bearer.
S16: the Trunking base station 12 sends a Group Call traffic Channel configuration (GCC) message on a Trunking Control Channel (TCCH).
In particular implementations, the cluster base station 12 may send GCC on a cluster control channel to give access stratum configuration parameters for the group TTCH. The NAS GROUP CALL setup message may also include a GROUP CALL setup message (GROUP CALL setup), where the NAS GROUP CALL setup message may carry one or more of the following information: call identification (Call ID), Call Type (Call Type), Media Type (Media Type), Service Type (Service Type), Call attribute (CallAttribute), Number of Call (Called Number), and Description of Media (Media Description).
It should be noted that, the cluster base station 12 may be one or more, and since the user equipment 11 in the group may be located at different positions, correspondingly, the cluster base station 12 to which the user equipment 11 belongs is also different, where the cluster base station 12 sends the GCC message, and each cluster base station sends the GCC message to the user equipment 11 in the group to which it belongs.
S17: the cluster core network device 13 sends a SIP (200OK) message to the group call initiator 14.
In a specific implementation, the trunking core network device 13 may send a SIP (200OK) message to the group call initiator 14 to notify the group call initiator 14 that the initiated group call is successfully established and granted its talk right. Wherein: the SIP message carries a pttaccept extension header field, and optionally carries Online Call identification information (Online Call ID).
S18: the group call initiator 14 sends a SIP Acknowledgement (ACK) message to the clustered core network device 13.
In a specific implementation, the group call initiator 14 may send a sip (ack) message to the trunking core network device 13 to confirm that the current group call is successfully established.
S19: the cluster core network device 13 transmits a speech right status indication message (NAS: FLOOR info).
In a specific implementation, the trunking core network device 13 may send an NAS message to the user equipment 11, so as to provide the sending right status indication information to the user equipment 11 listening to the group call.
In specific implementation, if the user equipment 11 is within the coverage area of the cell managed by the cluster base station 12, after the user equipment 11 receives the cluster paging signaling, the access AS layer of the user equipment 11 may send parameters, such AS the group ID of the group call, the group priority, and the identity information included in the group call paging, to the non-access layer of the user equipment 11, and when the non-access layer determines to receive the group call, the non-access layer may obtain the group resource configuration information and start receiving the group call, and may simultaneously determine whether the group call paging includes its own identity information, and if so, may feed back information representing that it is receiving the group call to the network side. When feeding back information representing that the user equipment is receiving the group call to the network side, the user equipment 11 may establish an RRC connection access network, and then indicate to the network side that the user equipment is receiving the group call. The network side comprises a cluster base station 12, a cluster core network device 13 and a scheduling management device. For example, for the UE2 in the user equipment 11, when the access stratum of the UE2 determines to receive the group call, the access stratum may acquire the group resource configuration information and start receiving the group call, and at the same time, since the group call paging includes its own identifier, the UE2 needs to feed back to the network side that it is receiving the group call.
In a specific implementation, the number of the user equipments 11 that need to feed back their own receiving of the group call state is an integer and is greater than or equal to 1, that is, one or more user equipments 11 that need to feed back their own receiving of the group call state may be provided.
In summary, it can be seen that the trunking core network device receives the group call establishment request information from the group call initiator, and includes indication information representing that the group call state needs to be fed back, and sends the indication information representing that the group call state needs to be fed back to the user equipment through the trunking base station, and when the user equipment receives the indication information, the indication information representing that the user equipment is receiving the group call is fed back to the trunking core network side, so that the network side can learn the UE participating in the group call communication.
In order to make those skilled in the art better understand and implement the present invention, a method for establishing a group call in the embodiment of the present invention is shown below, the method is suitable for establishing a group in a broadband trunking network, as shown in fig. 2, where the group may include n user equipments, n is an integer, and n > 1, and the method is described in detail with reference to fig. 2, and may include:
s21: and judging whether cluster paging signaling from the cluster base station is received or not.
In a specific implementation, S22 is performed when the cluster paging signaling is received from the clustered base station, and otherwise S21 may be performed.
S22: determining whether to receive the group call.
In a specific implementation, when a group call is in progress, the ue in the group may receive the group call, whether in an idle state or in a connected state, but the ue may determine whether to receive the group call when receiving a trunking paging signaling from a trunking base station to which the ue belongs, because of priority information of the group call and possibly due to its own state or other service requirements.
When it is determined to receive the group call, S23 is executed, otherwise, the process ends.
S23: and acquiring group resource configuration information and starting to receive the group call.
In an implementation, to receive the group call, when determining to receive the group call, the ue may obtain group resource configuration information and start receiving the group call.
S24: and judging whether the trunking paging signaling comprises indication information representing that the group calling state needs to be fed back or not.

S25: and feeding back information representing that the cluster core network side receives the group call.
In a specific implementation, when it is determined that the trunking paging signaling includes indication information representing that a group call state needs to be fed back, information representing that the trunking core network side is receiving the group call may be fed back to the trunking core network side, so that the network side knows the user equipment receiving the group call, thereby facilitating subsequent feedback operation. For example, if the group call initiator needs to listen to the opinion of the UE4 in the communication after the group call is established, the UE4 determines to receive the group call and feeds back that it has already received the group call, and then the group call initiator can ask questions of the UE4 or perform communication interaction with the UE at any time.
In an embodiment of the present invention, the indication information representing that the group call state needs to be fed back may be self identity information, that is, for n user equipments in the group, the user equipment side feeds back information representing that the user equipment side is receiving the group call only when the indication information includes self identity information.

S32: and sending a group paging command to the cluster base station, so that the cluster base station broadcasts a cluster paging signaling to the user equipment in the group in the cell under the jurisdiction of the cluster base station.
In a specific implementation, when receiving a group call establishment request message from a group call initiator, the group call initiator may send a group paging command to the trunking base station, so that the trunking base station broadcasts a trunking paging signaling to user equipment in the group in a cell under the jurisdiction of the trunking base station. And the group paging command and the cluster paging signaling can both carry the indication information representing that the group call state needs to be fed back.
S33: and receiving the information which is fed back by the user equipment and indicates that the user equipment is receiving the group call.
In a specific implementation, when the user equipment receives a trunking paging signaling of the trunking base station, if it is determined that the group call is received, it may be further determined whether the trunking paging signaling includes information indicating that the user equipment feeds back a state in which the user equipment is receiving the group call, and if it is determined that the trunking paging signaling includes indication information requiring the user equipment to feed back the state of the user equipment, it may send information indicating that the user equipment is receiving the group call to the trunking core network side, and the trunking core network side receives the information indicating that the user equipment feeds back the user equipment is receiving the group call, that is, it may know a state or a situation in which the user equipment receives the group call.

In order to improve the communication efficiency, in a specific implementation, when a trunking core network device sends a trunking paging signaling to each trunking base station, a user device that needs to feed back state information of the user device in the trunking paging signaling only includes a group user device in a cell under the jurisdiction of the trunking base station.
