The converged core network supports access of terminals in different modes (such as a broadband single-mode terminal, a narrowband single-mode terminal, a dual-mode dual-standby dual-pass terminal and a dual-mode single-standby single-pass terminal). As shown in fig. 1, in the prior art, each network element in the converged core network couples control and management of the broadband trunking service and the narrowband trunking service, and the existing network elements of the broadband and narrowband core networks are greatly modified, and a method for processing the trunking service involving the dual-mode dual-standby dual-pass terminal or the dual-mode single-standby single-pass terminal is not explicitly described.

In order to solve the above technical problem, the present application improves a structure of a converged core network, where fig. 2 is a schematic diagram of a system architecture of a broadband and narrowband converged network provided in this embodiment, and refer to the structure of the converged core network shown in fig. 2, where the converged core network includes a broadband trunking core network, a narrowband trunking core network, a convergence processing module, and a unified database;

As shown in fig. 2, the broadband trunking base station is connected to the converged core network through a PS1 interface, and further, the broadband trunking base station is connected to the broadband trunking core network through a PS1 interface. The narrowband cluster base station is connected with the converged core network through a PS2 interface, and further connected with the narrowband cluster core network through a PS2 interface.

The dual-mode dual-standby dual-pass terminal can reside (register) in two networks (namely a broadband cluster core network and a narrowband cluster core network), and supports concurrence of two network services at one moment, and a PU1 interface and a PU2 interface are simultaneously effective at the same moment. The dual-mode single-standby single-pass terminal only resides (registers) and uses services in one network, and only one of the PU1 interface and the PU2 interface is valid at the same time, which is indicated by a dotted line in FIG. 2.

The embodiment provides a converged core network, which includes a broadband cluster core network, a narrowband cluster core network, a converged processing module and a unified database. The broadband cluster core network is connected with the broadband cluster base station, the narrowband cluster core network is connected with the narrowband cluster base station, the control and management of the broadband cluster service and the narrowband cluster service are decoupled, the service processing flow is simplified, and the influence on the existing broadband and narrowband cluster core networks is reduced. For a dual-mode dual-standby bi-pass terminal or a dual-mode single-standby single-pass terminal, a mechanism of dual management of networks on two sides is adopted, when a core network is initialized, a unified database pushes the numbers and terminal types of all users which can be managed by the core network to a broadband core network and a narrowband core network, namely, the numbers and terminal types of all broadband single-mode terminals, dual-mode dual-standby bi-pass terminals and dual-mode single-standby single-pass terminals are pushed to the broadband core network, and the numbers and terminal types of all narrowband single-mode terminals, dual-mode dual-standby bi-pass terminals and dual-mode single-standby single-pass terminals are pushed to the narrowband core network; for a mixed group, a unified database pushes group service data to a fusion processing module, the fusion processing module respectively pushes group member lists capable of being managed by a broadband core network and a narrowband core network in the mixed group to the broadband core network and the narrowband core network according to group member types, namely, mixed group members stored in the broadband core network comprise a broadband single-mode terminal, a dual-mode dual-standby dual-pass terminal and a dual-mode single-standby single-pass terminal, and mixed group members stored in the narrowband cluster core network comprise a narrowband single-mode terminal, a dual-mode dual-standby dual-pass terminal and a dual-mode single-standby single-pass terminal.

The double-mode double-standby double-pass terminal and the double-mode single-standby single-pass terminal can adopt the same end-to-end flow, the service flow is unified, and the system is simple to realize.

Further, on the basis of the above embodiment, the system further includes a dispatching desk, where the dispatching desk is connected to the broadband trunking core network or the narrowband trunking core network;

As shown in fig. 2, the converged core network and the dispatching desk are connected through a PD interface.

It should be noted that, in the broadband and narrowband converged network system provided in this embodiment, the group may be divided into a "single group" and a "mixed group" according to different members. The single module consists of single-mode terminals and comprises a broadband single module consisting of broadband single-mode terminals and a narrowband single module consisting of narrowband single-mode terminals. A "hybrid group" member includes a dual-mode terminal, or both a wideband single-mode terminal and a narrowband single-mode terminal (i.e., not just a single-mode terminal). In the solution provided in this embodiment, if the broadband cluster core network receives the scheduling instruction sent by the scheduling station, the peer-to-peer network is the narrowband cluster core network, and if the narrowband cluster core network receives the scheduling instruction sent by the scheduling station, the peer-to-peer network is the broadband cluster core network.

Based on the converged core network provided by the embodiments, a converged processing module stores a registration state of a dual-mode terminal under networks on both sides (i.e., a broadband trunking core network and a narrowband trunking core network) and group service data of a mixed group, and when processing services, the converged processing module (1) determines a target trunking core network where a called terminal is located according to a terminal type, a current registration state and a preset policy and sends a single call establishment request to the target trunking core network if the terminal on a called side is the dual-mode terminal when receiving a single call establishment request sent by the trunking core network (the broadband trunking core network or the narrowband trunking core network); if the called terminal is a single mode terminal of the opposite terminal network, forwarding a single call establishment request to the opposite terminal network; (2) when receiving a group call establishment request of a mixed group sent by a cluster core network, respectively sending the group call establishment request to a broadband cluster core network and a narrowband cluster core network; (3) when receiving a mixed group talk right application sent by a cluster core network, sending a talk right result (authorization/queuing/refusal) to the network on the side according to the talk right strategy decision, and carrying out talk right notification to the networks on the two sides; (4) receiving a point-to-point cluster scheduling instruction (such as remoting and reviving) sent by a cluster core network connected with a scheduling station, if an operation object is a dual-mode terminal, determining a target core network according to the current terminal type, the registration state and a preset strategy of the dual-mode terminal, and sending a corresponding instruction to the target core network; if the operation pair is a single-mode terminal of the opposite-end network, the operation pair is fused with a transfer instruction of the processing module, and the instruction is not logically processed; (5) receiving an operation instruction (such as dynamic recombination) sent by a cluster core network connected with a dispatching station to a mixed group or an opposite-end network single module, and if a recombined terminal is a dual-mode terminal for the mixed group, sending a corresponding instruction to networks (a broadband cluster core network and a narrowband cluster core network) on two sides; if the recombined terminal is a single-mode terminal, issuing an instruction to a network at the side where the recombined terminal is located; and for the opposite-end network single module, forwarding the corresponding instruction to the opposite-end network, and processing the corresponding instruction by the opposite-end network.

Further, this embodiment provides a method for implementing a broadband and narrowband convergence service based on the above-mentioned converged core network, including:

Further, on the basis of the above embodiment, the method includes:

If different types of terminals/groups can be distinguished through number segments, the core network can acquire the types of the terminals/groups through code number analysis, and thus the code numbers of various terminals and groups need to be planned in a unified manner. The embodiment of the invention considers the universality, does not require the code number of each type of terminal/group, and adopts the following scheme to distinguish the types of the terminals/groups:

the subscription data of the cluster users/groups stored in the unified database comprises terminal/group types. For each user, the subscription data comprises a terminal type and is used for indicating a broadband single-mode terminal, a narrowband single-mode terminal, a dual-mode dual-standby dual-pass terminal and a dual-mode single-standby dual-pass terminal. For each group, the subscription data includes a group type, distinguishing between a broadband single module, a narrowband single module, and a hybrid group. In addition, in the member list of the mixed group, information of each member also includes a terminal type. When the fusion core network is initialized, the unified database pushes the numbers and terminal types of all users which can be managed by each cluster core network to both the broadband cluster core network and the narrowband cluster core network. That is to say, the numbers and terminal types of all the broadband single-mode terminals and dual-mode terminals are pushed to the broadband cluster core network, and the numbers and terminal types of all the narrowband single-mode terminals and dual-mode terminals are pushed to the narrowband cluster core network. Other subscription data of the user do not make requirements, and can be pushed during initialization or requested from the unified database during user cluster registration.

And when the group service data is initialized, if the group service data is a single module, the unified database pushes the service data of the single module managed by the unified database to the broadband cluster core network and the narrowband cluster core network. For a hybrid group, a unified database pushes group service data (including a group type, group subscription data and a group member list, wherein the group members include a terminal type) to a fusion processing module, the fusion processing module respectively pushes the group member list which can be managed by a broadband cluster core network and a narrowband cluster core network in the hybrid group according to the group member type of the hybrid group, that is, the hybrid group members stored in the broadband cluster core network include a broadband single-mode terminal and a dual-mode terminal, and the hybrid group members stored in the narrowband cluster core network include a narrowband single-mode terminal and a dual-mode terminal.

The following describes the processing procedures of group call, single call, dynamic recombination and telephoton, telephoton and revival in the cluster service based on the broadband and narrowband converged network architecture formed by the converged core network:

for group call service processing, on the basis of the above embodiments, the method includes: after receiving a group call establishment request sent by a terminal, a broadband cluster core network or a narrowband cluster core network judges whether the group call establishment request is a mixed group call or not according to the group call establishment request, if so, the group call establishment request is sent to a fusion processing module so as to respectively send the group call establishment request to the broadband cluster core network and the narrowband cluster core network through the fusion processing module;

after receiving the group call establishment request, the broadband cluster core network determines a first group call area according to online members in a first group member list stored in the broadband cluster core network, and informs a broadband base station in the first group call area to perform group call resource allocation;

after receiving the group call establishment request, the narrowband cluster core network determines a second group call region according to the online members in a second group member list stored in the narrowband cluster core network, and informs narrowband base stations in the second group call region to carry out group call resource allocation.

The first group member list is acquired from the fusion processing module when the broadband trunking core network is initialized (the first group service data pushed to the broadband trunking core network by the fusion processing module according to the type of the group members in the hybrid group comprises the first group member list), and the second group member list is acquired from the fusion processing module when the narrowband trunking core network is initialized (the first group service data pushed to the narrowband trunking core network by the fusion processing module according to the type of the group members in the hybrid group comprises the second group member list). The first group member list comprises a member list of group calling members of which the terminal types are a broadband single-mode terminal and a dual-mode terminal, and the second service data comprises a member list of group calling members of which the terminal types are a narrowband single-mode terminal and a dual-mode terminal; the dual-mode terminal comprises a terminal with the terminal types of dual-mode dual-standby dual-pass and dual-mode single-standby single-pass.

Further, the terminal type is that the single mode terminal is used as a calling party to send the group call establishment request to a broadband cluster core network or a narrowband cluster core network to which the single mode terminal belongs;

the terminal with the terminal type of dual-mode dual-standby dual-pass can select a mode according to a preset strategy (default configuration, automatic selection, manual selection and the like) as a calling party, and sends a group calling establishment request to a cluster core network determined by the mode;

and the terminal with the terminal type of double-mode single-standby single-pass is used as a calling party to send a group call establishment request to the currently resident cluster core network.

After the cluster core network receives a group call establishment request sent by a terminal through a cluster base station connected with the cluster core network, (1) if the cluster core network belongs to a single-mode group call initiated by a single-mode terminal as a calling party in the network, the service is directly processed in the network. For example, a broadband single-mode terminal sends a group call establishment request to a broadband cluster core network through a broadband cluster base station, and if a group member requesting for establishment of a group call is a single-mode terminal under the broadband cluster core network, the broadband cluster core network directly notifies the broadband cluster base station to allocate group call resources, and a fusion processing module is not required to participate in processing. (2) If the group call establishment is the group call establishment of the mixed group, after receiving the group call establishment request, the broadband or narrowband cluster core network sends the group call establishment request to the fusion processing module, and the fusion processing module informs the broadband cluster core network and the narrowband cluster core network to carry out the group call establishment of the called side. The broadband cluster core network and the narrowband cluster core network determine a group calling area according to online members of the hybrid group in the network, and inform base stations in the group calling area to distribute group calling resources.

Regarding the determination of the group call area, it should be noted that when the converged core network is initialized, the converged processing module obtains service data (including a group type, group subscription data, and a group member list) of the hybrid group from the unified database, and pushes group service data related to the broadband and the narrowband clustered core networks, respectively. For group members, pushing a member list which can be managed by each network to each network, pushing a group member list comprising a broadband single-mode terminal and a dual-mode terminal to a broadband side, and pushing a group member list comprising a narrowband single-mode terminal and a dual-mode terminal to a narrowband side, wherein the dual-mode terminal comprises a dual-mode dual-standby dual-pass terminal and a single-standby single-pass terminal. For the dual-mode dual-standby dual-pass terminal, because the terminals reside in both the broadband network and the narrowband network, the distribution of the terminals needs to be considered when the broadband cluster core network and the narrowband cluster core network determine the group calling area; for the single-standby single-pass terminal, because the terminal only resides in one network at the same time, and the other network is not online, the distribution of the terminal only needs to be considered in the currently residing network of the terminal when the group calling area is determined.

The method for implementing the wideband-narrowband convergence service provided in this embodiment may dynamically determine the group call region according to the distribution of the group members, and this way may save air interface resources, and only establish the group call resources in the user region, and of course, the core networks on both sides, especially the narrowband cluster core network, may also determine the group call region according to other ways such as pre-configuration, and allocate channel resources.

To further explain the processing procedure of the group call service, fig. 3 is a schematic diagram of a flow of initiating a mixed group call by a broadband single-mode terminal provided in this embodiment, referring to fig. 3, where the flow includes the following steps:

step 1: a calling terminal (broadband single-mode terminal) sends a group call establishment request to a broadband cluster core network;

step 2: the broadband cluster core network judges the group call of the mixed group according to the group type in the locally stored group service data, and sends a group call establishment request to the fusion processing module;

and step 3: the fusion processing module respectively sends a group call establishment request to the broadband cluster core network and the narrowband cluster core network; the broadband cluster core network determines a group calling area according to online members of the mixed group under the cluster core network at the side, and the narrowband cluster core network determines the group calling area according to online members of the mixed group under the cluster core network at the side;

and 4, step 4: the broadband cluster core network and the narrowband cluster core network inform base stations in a group calling area under the network to establish group calling, and a called terminal can receive the group calling after receiving corresponding air interface messages; for a single-mode terminal, receiving a group call in a single-side network to which the single-mode terminal belongs; for the dual-mode dual-standby dual-pass terminal, the group call can be received by the network at both sides of the broadband and the narrowband, and the specific selection mode of the terminal can be determined by the implementation; for a dual-mode single-standby single-pass terminal, receiving a group call in a currently resident single-side network;

and 5: the fusion processing module sends a group call establishment response to the calling terminal through the broadband cluster core network, informs the successful establishment of the group call, and the calling terminal obtains an initial talk right;

step 6: the fusion processing module respectively sends a speaking right notice to the broadband cluster core network and the narrowband cluster core network to inform a current speaker;

and 7: the wideband cluster core network and the narrowband cluster core network respectively carry out speaking right notification to the members in the group in the network.

If the members in the group need to talk subsequently, the broadband or narrowband cluster core network sends the speaking right application to the fusion processing module after receiving the speaking right application of the terminal of the local network, and the fusion processing module sends a speaking right result (authorization/queuing/refusal) to the network on the side according to the speaking right strategy decision and informs the networks on the two sides of the speaking right.

It should be noted that, taking the broadband side as an example, the call control message shown in the figure is a non-access stratum NAS message between the terminal and the core network, and the base station only performs transparent transmission, so the base station is not shown in the flowchart, and an air interface RRC message and an S1 interface message for carrying the NAS message are not shown.

For the single call service processing, on the basis of the above embodiments, the method includes:

Specifically, if a single-mode terminal in the same trunking core network (broadband trunking core network or narrowband trunking core network) calls another single-mode terminal in the trunking core network, the convergence processing module is not required to participate in processing the single-mode call service. The following is a single call service which needs the convergence processing module to participate in processing.

On the basis of the foregoing embodiments, the converged core network provided in this embodiment includes:

after receiving a single-call establishment request sent by a terminal, a cluster core network in the converged core network sends the single-call establishment request to a converged processing module if the called terminal is judged to be a dual-mode terminal or a single-mode terminal which is not the cluster core network according to the single-call establishment request, so that the converged processing module determines a target cluster core network at a called side and sends the single-call establishment request to the target cluster core network.

Further, still include: if the fusion processing module judges that the type of the called terminal is a dual-mode dual-standby dual-pass terminal according to the single-call establishment request, determining a target cluster core network of the called side according to the type of the terminal corresponding to the called terminal, the current registration state and a preset strategy, and sending the single-call establishment request to the target cluster core network;

if the type of the called terminal is judged to be a single-standby single-pass terminal according to the single-call establishment request, taking a cluster core network where the called terminal currently resides as a target cluster core network, and sending the single-call establishment request to the target cluster core network;

and if the type of the called terminal is judged to be the single mode terminal of the opposite terminal cluster core network according to the single call establishment request, the opposite terminal cluster core network is used as a target cluster core network, and the single call establishment request is sent to the target cluster core network.

For the dual-standby dual-pass terminal residing in the networks on both sides, the convergence processing module may determine the target trunking core network by combining a preset policy (e.g., preferentially selecting a broadband network or a narrowband network, where the execution main body is the convergence processing module) to send the single-call establishment request to the target trunking core network.

Further, for the terminal, if the terminal type corresponding to the calling terminal is a dual-mode dual-standby dual-pass terminal, the terminal selects a mode according to a preset policy (default configuration, automatic selection, manual selection, and the like, which is different from the preset policy of the called side, and the execution main body is the calling terminal), and sends a single call establishment request to the trunking core network determined by the mode;

and if the terminal type corresponding to the calling terminal is the single-standby single-pass terminal, sending a single-call establishment request to a cluster core network where the terminal currently resides.

firstly, it needs to be noted that, during initialization, the broadband cluster core network obtains the numbers and types of all terminals which can be managed by the broadband cluster core network from the unified database, including broadband single-mode terminals and dual-mode terminals; similarly, the narrowband cluster core network acquires the numbers and types of all narrowband single-mode terminals and dual-mode terminals from the unified database, wherein the dual-mode terminals comprise dual-mode dual-standby dual-pass and dual-mode single-standby single-pass.

Step 1: a calling terminal sends a single call establishment request to a broadband/narrowband cluster core network, and when the calling terminal is a single-mode terminal or a dual-mode single-standby single-pass terminal, the currently resident cluster core network is selected; if the calling terminal is a dual-mode dual-standby dual-pass terminal, selecting a network to send a single-call establishment request according to a preset strategy;

the broadband/narrowband cluster core network judges whether the called party is a single-mode terminal of the network according to the locally stored user number and the terminal type which can be managed by the core network.

Step 2: the broadband/narrowband cluster core network sends a single call establishment request to the convergence processing module. Preferably, the single call establishment request carries the called terminal type, which indicates a dual-standby dual-call terminal and a single-standby single-call terminal, and if the single-call establishment request is a single-mode terminal of an opposite-end network, the terminal type can be defined to a certain value;

step 5a-8 a: the called dual-mode terminal returns a single-call establishment response to the calling terminal through the target cluster core network, the fusion processing module and the cluster core network selected by the calling terminal;

if the called terminal is a single-mode terminal of the opposite terminal network, executing the steps 3b-8 b:

For the dynamic reconfiguration service(s), taking the architecture that the dispatching desk shown in fig. 2 is connected to the broadband cluster core network as an example, if the dynamic reconfiguration operation is performed on the broadband single module, the fusion processing module may not participate in processing the service; if the operation of dynamic recombination is carried out on the narrow-band single module, the instruction needs to be sent to the narrow-band network through the fusion processing module, wherein the fusion processing module only forwards the signaling and does not process the instruction; if dynamic recombination operation is performed to the mixed group, see the flow shown in fig. 5.

Specifically, after a first scheduling instruction from another cluster core network is received for the second time, the dynamic reassembly related information carried in the first scheduling instruction is ignored, and if the first scheduling instruction includes the group attribute information, only the update of the group attribute is executed.

Specifically, for the dynamic restructuring operation of the hybrid group, if the restructured object is a single-mode terminal, the fusion processing module sends a dynamic restructuring instruction to a core network to which the terminal belongs according to the locally stored terminal type of the hybrid group member; if the operation object is a dual-mode terminal (including dual-standby dual-channel and single-standby single-channel), considering that the broadband and narrowband networks have management authority on the dual-mode terminal, and the dynamic restructuring instruction relates to some information specific to the broadband and narrowband networks, for example, on one side of the broadband network, when a user is added into a group after a group call air interface encryption is started, specific information such as a group root key, a key version number, an NAS layer encryption algorithm and the like needs to be pushed to the user, so that the dynamic restructuring instruction is sent to the networks on two sides of the broadband and narrowband for the dual-mode terminal; and on the terminal side, only once operation for changing the association relationship between the user and the group is executed, after a dynamic restructuring instruction of the network on one side is received, the corresponding operation is executed, the terminal is added into the group/the group attribute is deleted/updated from the group, and for the subsequent received dynamic restructuring instruction from the network on the other side, other operations are ignored, and only the updating of the group attribute is executed.

It should be noted that the dual-mode terminal receives the management of both sides of the broadband and the narrowband, and for the dynamic reassembly service, receives the instruction issued by the networks on both sides, but only executes the operation of changing the association relationship between the user and the group once. After receiving the dynamic restructuring instruction of the network at one side, the terminal executes the corresponding operation of adding to the group or deleting from the group, and ignores other operations for the dynamic restructuring instruction from the network at the other side, if the instruction carries group attribute information, only updates the group attribute. If the terminal is added into the group, the dual-mode terminal adds the group into the group to which the dual-mode terminal belongs after receiving the instruction of the network at one side and stores the related group attribute, and then does not execute the change of the group association relation any more and only receives the group attribute information in the signaling when receiving the instruction from the network at the other side; if the terminal is deleted from the group, the dual-mode terminal deletes the group in the group after receiving the instruction of the network at one side, and ignores the subsequent instruction from the network at the other side.
