DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention examples.
The long term evolution (Long Term Evolution, LTE) of The fourth generation mobile communication (Fourth generation mobile communication, 4G) is a long term evolution of The universal mobile telecommunication system (Universal Mobile Telecommunications System, UMTS) technical standard established by The third generation partnership project (The 3rd Generation Partnership Project, 3 GPP).
Generally, the LTE network architecture includes the following three main components: user Equipment (UE), evolved UMTS terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network E-UTRAN), and packet core evolution (Evolved Packet Core EPC).
Further, the UE may be a mobile terminal such as a mobile phone, a tablet, or a computer, and is connected to the E-UTRAN through an LTE-Uu interface. The E-UTRAN may be composed of a plurality of evolved NodeBs (eNodeBs) interconnected with each other through an X2 interface, and the E-UTRAN is connected with the EPC through an S1 interface.
The EPC mainly includes five major network elements: a mobility management entity (Mobility Management Entity, MME), a Service GateWay (SGW), a packet data network manager (Packet Data Network GateWay, PGW), a home subscriber server (Home Subscribers Server, HSS), a policy and charging rules function (Policy and Charging Rules Function, PCRF).
The MME is a control plane serving a general packet radio service support node (Serving General packet radio service, abbreviated as SGSN), and is responsible for handling signaling of user services, for completing management of mobile users, and interacting with eNodeB, HSS and SGW. The MME is connected with the HSS through an S6a interface, is connected with the SGW through an S11 interface, and is connected with the base station eNodeB through an S1-MME interface, and the interfaces are all based on IP protocol.
The SGW functions in concert with the MME. In short, the SGW is the service plane of the SGSN, and is responsible for handling the user's service, so as to complete the bearer of the mobile data service. And interacts with devices such as eNodeB, MME and PGW. The SGW is connected to the MME through an S11 interface, connected to the PGW through an S5 or S8 interface (differentiated in roaming service processing, for example, the same operator uses an S5 interface, and a different operator uses an S8 interface), and connected to the base station eNodeB through an S1-U interface, which are all based on IP protocols.
The PGW functions very much like a gateway GPRS support node (Gateway GPRS Support Node, GGSN for short), is responsible for interfacing with the Internet and interacting with PCRF and PGW devices. The PGW is connected with the SGW through an S5 or S8 interface, is connected with the PCRF through a Gx interface, is connected with the PDN through an SGi interface, and is based on an IP protocol. PGWs do not directly cross-track with the base station eNodeB.
The HSS is a central database containing subscriber related information and subscription related information. The functions of the HSS include: mobility management, support for call and session establishment, user authentication and access authorization.

Fig. 5 is a schematic flow chart of a trunking communication method according to the present invention, where the trunking communication method is applied to the trunking communication system shown in fig. 3 or 4. As shown in fig. 5, the trunking communication method includes:
step 101, the base station acquires capability information of the terminal.
Specifically, the capability information includes terminal access network capabilities including access 4G network capabilities and access 5G network capabilities and LTE B-trunk service capabilities. For example, for a 4G LTE B-trunk trunked terminal, it is capable of accessing a 4G network and LTE B-trunk service; for a 5G data terminal, the terminal has the capability of accessing a 5G network, but does not have the LTE B-trunk C service capability; for a 5G NSA B-TruC terminal (LTE B-TruC/NR dual-mode terminal), the function of supporting B-TruC trunking by an LTE mode and trunking data concurrence are provided. In this step, the base station may acquire capability information of each terminal.
Step 102, the base station responds to the cluster service request initiated by the terminal, and establishes cluster service bearing according to the capability information of the terminal.
Specifically, a terminal (mobile terminal or a dispatching desk) initiates a trunking service request to a network side device of a trunking communication system, and a base station of the network side device establishes a bearer according to capability information of each terminal in a trunking group. For example, if the terminal has the capability of accessing the 4G network and has the capability of LTE B-trunk service, a bearer is established according to the multicast technology of LTE B-trunk; if the terminal has the capability of accessing the 5G network and the LTE B-trunk service capability, the terminal is controlled to fall back to a 4G mode, and a bearing is established according to the multicast technology of the LTE B-trunk; if the terminal has the capability of accessing the 5G network but does not have the LTE B-trunk service capability, the bearer is established according to a 4G or 5G unicast mode.
Step 103, the terminal performs cluster service data transmission on the bearer.
The terminal determines the bearer according to bearer information sent by the base station.
Specifically, after the bearer is established, the base station of the network side device may notify the bearer of the terminal group in the group, and the group terminal receives the cluster data according to the notified bearer resource. For example, an LTE B-trunk C terminal in an LTE base station control group resides in an LTE cell and receives B-trunk C downlink data; triggering a 5G NSA terminal (LTE B-TruC/NR dual-mode terminal) to fall back to a 4G mode if the 5G NSA terminal has LTE B-TruC service supporting capability, and residing in an LTE cell to receive B-TruC cluster data; and the main speaking users in the group send uplink group data, and uplink bearing sending data is established in the LTE cell by default.
According to the trunking communication method provided by the invention, the capability information of the terminal is acquired through the base station; the base station responds to a trunking service request initiated by a terminal and establishes trunking service bearing according to capability information of the terminal; the terminal performs cluster service data transmission on the bearer, wherein the terminal determines the bearer according to bearer information sent by a base station, so that the support and smooth evolution of the old and B-trunk cluster services of the LTE terminal are realized in the evolution process of the LTE B-trunk system to 5G; or under the condition that the B-trunk 5G multicast standard and the industry chain are not mature, a 5G network supporting the B-trunk cluster service is newly established.
With reference to the foregoing embodiments, fig. 6 is an interaction schematic diagram of another trunking communication method according to the present invention, as shown in fig. 6, where the trunking communication method includes:
step 201, a cluster processing network element device of a core network receives a network access registration request of a terminal, wherein the network access registration request carries capability information of the terminal.
Step 202, the cluster processing network element equipment sends the capability information of the terminal to a base station.
Correspondingly, the base station receives capability information of a terminal sent by the cluster processing network element device, wherein the capability information of the terminal is obtained by the cluster processing network element device in response to a network access registration request of the terminal, and the network access registration request carries the capability information of the terminal.
Step 203, the cluster application server responds to a cluster service request initiated by the terminal, determines a corresponding quality of service QoS parameter according to the cluster service request, and establishes a first bearer between the cluster application server and the core network according to the QoS parameter.
Step 204, the cluster application server sends the QoS parameter to the cluster processing network element device, and the cluster processing network element device establishes a second bearer between the core network and the base station according to the QoS parameter.
Step 205, the trunking network element device sends the QoS parameter to the base station, and the base station establishes a third bearer between the base station and the terminal according to the QoS parameter and the capability information of the terminal, where the third bearer is the trunking service bearer.
Step 206, the terminal performs cluster service data transmission on the bearer.
The terminal determines the bearer according to bearer information sent by the base station.
Step 206 in this embodiment is similar to step 103 in the previous embodiment, and will not be described here.
Different from the foregoing embodiment, the present embodiment further defines a specific implementation procedure of bearer resource establishment in a trunking communication system, in this embodiment, the base station receives capability information of a terminal sent by the trunking network element device, where the capability information of the terminal is obtained by the trunking network element device in response to a network access registration request of the terminal, where the network access registration request carries capability information of the terminal; the method comprises the steps that a cluster application server responds to a cluster service request initiated by a terminal, corresponding QoS parameters are determined according to the cluster service request, and a first bearing between the cluster application server and a core network is established according to the QoS parameters; the cluster application server sends the QoS parameters to the cluster processing network element equipment, and the cluster processing network element equipment establishes a second bearer between a core network and a base station according to the QoS parameters; and the cluster processing network element equipment sends the QoS parameters to the base station, and the base station establishes a third bearing between the base station and the terminal according to the QoS parameters and the capability information of the terminal, wherein the third bearing is the cluster service bearing.
Specifically, when the terminal performs network access registration with the core network, the capability information of the terminal is carried, where the capability information includes access wireless network capability, that is, access 4G network capability (also referred to as access LTE wireless network capability) and access 5G network capability (also referred to as access NR wireless network capability); the capability information further includes whether the terminal supports LTE B-trunk service capability, for example, the LTE terminal carries B-trunk trunking service supporting capability, B-trunk trunking service supporting capability of 5G NSA terminal supporting LTE mode, and B-trunk trunking service supporting capability of NR mode.
Then, the core network transmits the acquired capability information of each terminal to the LTE B-trunk base station and the NR base station.
Then, if there is a terminal or a dispatcher station that initiates a cluster service request to a cluster application server, the cluster application server responds to the request to determine a corresponding QoS policy (also referred to as PCF policy).
And then, the core network establishes a cluster service bearer corresponding to the group according to a PCF strategy triggered by the cluster application server and a designated cluster QoS, and after the establishment of the core network is completed, an instruction is sent to the base station so that TCF network element equipment of the base station analyzes B-trunk group supporting capability and access network capability of all terminals in the group and determines an establishing mode of the group bearer. Specifically, the LTE base station establishes the bearing of B-trunk group service according to the analysis terminal B-trunk group capacity and network capacity; and establishing a downlink bearer of a B-trunk cluster for an LTE base station in an LTE B-trunk multicast mode, and establishing a cluster unicast bearer for a 5G unicast and an uplink bearer of a group user according to a unicast mode by the base station. The LTE base station informs the bearing of the terminal group in the group, and the group terminal receives cluster data according to the notified bearing resource; an LTE-trunk C terminal in the LTE base station control group resides in an LTE cell and receives B-trunk C downlink data; triggering a 5G NSA terminal (LTE B-TruC/NR dual-mode terminal) to fall back to a 4G mode if the 5G NSA terminal has LTE B-TruC service supporting capability, and residing in an LTE cell to receive B-TruC cluster data; and the main speaking users in the group send uplink group data, and uplink bearing sending data is established in the LTE cell by default. If the group contains 5G data terminals, the 4G unicast or 5G unicast mode is adopted to support the cluster service.
