Description

Service scheduling method and device and cluster system without central node

Technical Field

The present invention relates to the field of trunking communication technologies, and in particular, to a service scheduling method and apparatus, and a trunking system without a central node.

Background

The cluster system without the central node refers to a cluster system implemented based on the P2P technology, which is different from a real cluster system, and there is no central node with strong central processing capability in the system to be responsible for service scheduling. As shown in fig. 1, a typical cluster system without a central node includes a plurality of sites, a plurality of base station devices under each site form a plurality of channel resources, and the sites are connected to each other through switches and routers.

Because the above-mentioned cluster system without the central node has no central node and does not have the processing capability of the cluster system, if the service scheduling is performed as the access cluster system, the load of a single base station device in the cluster system is large, the coding and decoding tasks of the multi-path voice data cannot be completed, and the cluster system cannot be used as a server device to realize the dynamic group calling function of the scheduling station.

In order to solve the problem of service scheduling of the cluster system without the central node, in the prior art, a manner of adding a scheduling system to the cluster system without the central node is often adopted, and the scheduling system is connected with each base station of the system, so that the scheduling processing of services of each base station is realized. In the above implementation manner, the scheduling system needs to know the implementation logic of the cluster system in detail, and needs to be connected to each base station of each site of the cluster system to obtain the idle state information of each base station, which is relatively complex to implement.

Detailed Description

The technical scheme of the embodiment of the invention is suitable for the service scheduling application scene of the cluster system without the central node. By adopting the technical scheme of the embodiment of the invention, the service scheduling of the cluster system without the central node can be realized under the condition of not needing a scheduling system gateway.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a service scheduling method, which is suitable for a cluster system without a central node.

In the cluster system without a central node shown in fig. 1, in the embodiment of the present invention, the host of one of the sites is set as an access point base station, and the subnet hosts of other sites are set as site registration base stations. In addition, the access point base station of the cluster system without the central node in the embodiment of the invention is configured to be an external address allowing the dispatching station to access, and is used for communicating with an external network. It can be understood that, in the embodiment of the present invention, an access point base station in a cluster system without a central node is actually used as a gateway, so that the communication connection between the cluster system without the central node and an external dispatching desk is realized, and no additional separate external gateway is required.

Further, in the embodiment of the present invention, after networking of the cluster system without the central node is completed, each scheduling station of the scheduling system registers ID information and received group call list information with the access point base station, and each site registration base station also registers its received group call list with the access point base station. For example, as shown in fig. 2, assuming that Repeater1-1 is an access point base station, a console (console 1, console 2, console 3) registers ID information and group call group information belonging thereto to access point base station Repeater1-1, that is, receives group call list information; a site registration base station (Repeater2-1) of each site registers the group calling group information to which the site registration base station belongs to the Repeater1-1, namely receives the group calling list information; repeater1-1 records the IP addresses of all participants and receives group list information.

Based on the above arrangement, the cluster system without the central node provided in the embodiment of the present invention includes four types of base stations: access point base stations, site registration base stations, idle base stations, and busy base stations. The idle base station, that is, the base station having idle bandwidth resources in the trunking system and capable of processing service data, the busy base station, that is, the base station having no idle bandwidth resources in the trunking system, and the idle base station and the busy base station may be switched to each other. In the following, the embodiments of the present invention respectively describe the specific implementation processes of the service scheduling method proposed in the present invention in terms of an access point base station, a site registration base station, and an idle base station.

When a dispatching station initiates a call to a cluster system without a central node, referring to fig. 3, a service dispatching method of an access point base station applicable to the cluster system provided by the embodiment of the present invention includes:

s301, receiving first service request information sent by a dispatching desk;

specifically, the first service request information includes service member information, that is, information about which scheduling stations or terminals are required by the service to participate.

When the access point base station receives the first service request information, it first identifies whether the first service request information is individual call service request information or group call service request information.

If the first service request message is a paging service request message, the access point base station executes step S302, broadcasts the paging request message to the trunking system, confirms the idle base station where the target terminal is located, and establishes call connection for the dispatching station and the idle base station where the target terminal is located, so that the dispatching station and the idle base station where the target terminal is located directly perform voice data transmission;

specifically, after receiving the individual call service request information sent by the scheduling station, the access point base station needs to determine a target terminal of the individual call service request. The access point base station searches a target terminal from a cluster system without a central node in a paging mode: the base station of the access point broadcasts the calling request information to the site, and simultaneously forwards the calling service request information to other sites, so that the base stations of other sites broadcast the calling request information to the site. The paging request information carries all information in the paging service request information received by the access point base station.

After receiving the individual calling request broadcast by the base station, the target terminal checks whether the individual calling request is the individual calling request information of the calling itself, if the individual calling request is the individual calling request information of the calling itself, response information is sent to the idle base station of the site where the target terminal is located, the idle base station sends the response information to the access point base station, and the access point base station can determine the target terminal and determine the idle base station where the target terminal is located.

Then, the access point base station establishes call connection between the dispatching station and the space base station where the target terminal is located, that is, establishes a data link between the dispatching station and the idle base station. The voice data transmission can be directly carried out between the dispatching station and the idle base station through the data link, and the idle base station carries out coding and decoding processing on the voice data without forwarding by the access point base station.

It can be understood that when the access point base station receives the downlink individual call service request information, it is only responsible for service scheduling, and builds a data link between the scheduling station and the idle base station where the individual call service target terminal is located, and does not participate in a specific data transmission process. Because the downlink individual calling service is carried out between the idle base station and the dispatching station, the service load of the access point base station is not increased. And if the target terminal is in the site where the access point base station is located and the access point base station is an idle base station under the site, carrying out individual call service voice data transmission by the access point base station and the dispatching station.

If the first service request message is a group call service request message, the ap base station performs step S303 to confirm the target bs and the target site according to the stored received group call list information of each bs and the received group call list information of each site registration bs;

specifically, when the first service request message sent by the scheduling station is a group call service request message, the group call member message is carried in the group call service request message. The access point base station determines the group calling member information contained in the group calling by analyzing the received first service request information, and further determines the target scheduling station and the target site contained in the group calling by inquiring the stored group calling list receiving information of each scheduling station and the group calling list receiving information of each site registration base station. It is to be understood that the target scheduler refers to a scheduler other than the scheduler that transmits the first service request information, and the target scheduler and the target station may be one or more, or may only include the target station and not include the scheduler.

S304, the access point base station sends group calling request information to the target dispatching station and the station registration base station with the minimum load in the target station, so that the station registration base station with the minimum load selects an idle base station in the station to be responsible for voice data coding and decoding;

specifically, after determining a target scheduling station and a target site included in a group call service, the ap base station sends group call request information to the target scheduling station, and sends group call request information to a site registration base station with the smallest load in the target site included in the group call service. If the group calling does not contain the dispatching desk, the group calling request information is only sent to the site registration base station with the minimum load in the target sites contained in the group calling service without sending the group calling request information to the target dispatching desk.

Specifically, in the embodiment of the present invention, after receiving the group call request information, the station registration base station with the smallest load in the target stations selects an idle base station from the stations where the idle base station is located, and is responsible for the encoding and decoding processing of the voice data, specifically performs decoding on the received scheduling station voice data and sends the decoded voice data to each terminal included in the group call, and encodes the voice data sent by the terminal included in the received group call and sends the encoded voice data to the access point base station.

After receiving the group call service voice data sent by the dispatching station, the access point base station executes step S305 to forward the received group call service voice data to the idle base station, so that the idle base station sends the group call service voice data to each terminal belonging to the group call after finishing the voice data decoding;

specifically, after receiving the downlink group call service voice data sent by the scheduling station, the ap base station forwards the group call service voice data to the idle base station, and the idle base station decodes the group call service voice data and then sends the decoded voice data to each terminal included in the group call by using a data link inside the cluster system without the central node.

When the terminal in the group call sends the voice data of the uplink group call service, the voice data is sent to the idle base station, and the idle base station encodes the received voice data and then sends the encoded voice data to the access point base station.

After receiving the encoded group call service voice data sent by the idle base station, the ap base station executes step S306 to forward the received group call service voice data to the dispatching station.

It can be understood that, in the uplink and downlink transmission process of the group call service voice data, the access point base station is only responsible for forwarding the data, but does not perform specific data encoding and decoding processing, the real encoding and decoding work is completed by the idle base station, and the idle base station is responsible for the transmission of the group call service voice data in the cluster system without the central node, so that the purpose of performing service scheduling by the access point base station and performing service processing by the idle base station is achieved, and the service scheduling without increasing the load of the access point base station or increasing the scheduling system is achieved.

The other embodiment of the invention also discloses a technical scheme for the access point base station to carry out uplink service scheduling. When a terminal in a cluster system without a central node requests an uplink service, firstly, a service request is initiated to an idle base station in a site, and then the idle base station determines whether to forward the service request initiated by the terminal to an access point base station according to a specific service requirement.

If the call initiated by the terminal is an individual call or a group call in the cluster system and data transmission between the cluster system and an external scheduling system is not needed, the idle base station directly executes service forwarding to realize data transmission in the cluster system. If the call initiated by the terminal needs to participate in the scheduling system, the service request needs to be forwarded to the access point base station, and the access point base station realizes the forwarding of the service request to the scheduling station of the scheduling system and realizes the service scheduling.

The embodiment of the invention only takes the situation that the call initiated by the terminal needs the dispatching desk to participate as an example, and explains the process of realizing the service dispatching by the access point base station.

Referring to fig. 4, an uplink service scheduling method applied to the access point base station according to an embodiment of the present invention includes:

s401, receiving second service request information sent by an idle base station;

specifically, the second service request information includes service member information, that is, information about which scheduling stations or terminals are required by the service to participate. It can be understood that the second service request message may be a request message for inviting a terminal in the trunking system to perform a call service, may also be a request message for inviting a dispatching station to perform a call service, and may also be a request message for inviting the dispatching station and the trunking terminal to perform a group call service at the same time. The embodiment of the invention takes the second service request information as the service request information needing the participation of the dispatching station as an example to explain the service dispatching processing process of the access point base station.

After receiving the second service request information, the access point base station firstly analyzes and identifies the second service request information, and confirms whether the second service request information is individual call service request information or group call service request information.

If the access point base station confirms that the second service request information is the individual calling service request information, executing step S402, confirming the target dispatching station according to the stored information of each dispatching station, and establishing calling connection between the target dispatching station and the idle base station to enable the target dispatching station and the idle base station to directly transmit voice data;

specifically, after receiving individual call service request information sent by the idle base station, the access point base station needs to determine a target scheduling station of the call service request, and specifically, the access point base station determines the target scheduling station and IP address information of the target scheduling station by querying stored scheduling station information. Then, the access point base station establishes call connection between the target dispatching station and the idle base station, and establishes a data link between the target dispatching station and the idle base station. The voice data transmission can be directly carried out between the dispatching station and the idle base station through the data link, and the idle base station carries out coding and decoding processing on the voice data without forwarding by an access point base station.

It can be understood that when the access point base station receives the uplink individual call service request information, it is only responsible for service scheduling, and builds a data link between the scheduling station and the idle base station, and does not participate in a specific data transmission process. Because the uplink calling service is carried out before the idle base station and the dispatching station, the service load of the access point base station is not increased.

If the second service request message is a group call service request message, the ap base station performs step S403 to confirm the dispatch stations belonging to the group call service according to the stored group call list receiving information of each dispatch station;

specifically, when the second service request information sent by the idle base station is the group call service request information, the group call member information is carried in the group call service request information. The access point base station determines the group calling member information contained in the group calling service by analyzing the received second service request information, and further determines the dispatching stations belonging to the group calling service by inquiring the stored group calling list receiving information of each dispatching station. The number of the dispatching stations belonging to the group calling service can be one or more.

It can be understood that the group call service may actually include terminals in a cluster system without a central node, and for the terminals in the cluster system without the central node, the idle base station may implement voice data transmission between them without forwarding scheduling by the access point base station, so that detailed description is not provided in the embodiment of the present invention.

After the access point base station receives the group call service voice data sent by the dispatching station belonging to the group call service, step S404 is executed to forward the received group call service voice data to an idle base station and/or other dispatching stations belonging to the group call service;

specifically, when a certain scheduling station in the group call sends voice data, the ap base station receives the voice data, and forwards the received voice data to the idle base station in the cluster system without a central node and other scheduling stations belonging to the group call. After receiving the voice data sent by the access point base station, the idle base station in the cluster system without the central node decodes the received voice data and forwards the decoded voice data to each terminal belonging to the group call in the cluster system.

When the terminal in the group call sends the voice data, the voice data is sent to the idle base station, the idle base station carries out coding processing on the received voice data, and then the coded voice data is forwarded to the access point base station.

After receiving the encoded group call service voice data sent by the idle base station, the ap base station executes step S405 to forward the received group call service voice data to the scheduling station belonging to the group call service.

Optionally, in another embodiment of the present invention, a service scheduling method applied to a site registration base station in the cluster system without a central node shown in fig. 1 is also disclosed. It can be understood that the method is a service scheduling method applicable to a station registration base station in a cluster system without a central node, corresponding to the service scheduling method applicable to an access point base station in the cluster system without a central node described above.

In the embodiment of the present invention, in the cluster system without a central node shown in fig. 1, the host of one of the sites is also set as the access point base station, and the subnet hosts of other sites are set as the site registration base stations. In addition, the access point base station of the cluster system without the central node in the embodiment of the invention is configured to be an external address allowing the dispatching station to access, and is used for communicating with an external network.

Further, in the embodiment of the present invention, after networking of the cluster system without the central node is completed, referring to fig. 2, each scheduling station of the scheduling system registers ID information and received group call list information with the access point base station, and each site registration base station also registers its received group call list with the access point base station.

For individual call service in a cluster system without a central node, it can be determined according to the method embodiments shown in fig. 3 or fig. 4 that idle base stations in the cluster system can complete the individual call service without the participation of a station registration base station in the cluster system. Moreover, when a terminal in the trunking system initiates an uplink group call service, the terminal also completes the uplink group call service through the idle base station and the access point base station, so that the embodiment of the invention only takes the scenario that the scheduling station initiates a downlink group call service as an example to explain the specific processing process of the station registration base station in the downlink group call service scheduling process.

When the dispatching station initiates a downlink service request to the cluster system without the central node, because only the access point base station in the cluster system without the central node has an external address which can be accessed by the dispatching station, the dispatching station firstly sends the service request to the access point base station, and then the access point base station sends the service request to the site registration base station, which is named as third service request information.

It should be noted that, when the scheduling station initiates the downlink group call service, the access point base station will forward the received downlink group call service request to the less-loaded site registration base station in the cluster system without the central node, so that the site registration base station implementing the technical scheme of the embodiment of the present invention is actually selected by the access point base station, and the less-loaded site registration base station.

The process of the station registering the base station is shown in fig. 5:

s501, receiving third service request information sent by an access point base station;

after the station registration base station receives the third service request information sent by the access point base station, the third service request information is firstly analyzed to confirm whether the request information is individual call service request information or group call service request information, and the individual call service and the uplink group call service are directly completed by the idle base station, so the third service request information is the group call service request information forwarded by the access point base station.

It can be understood that, if the station registration base station itself is used as an idle base station under the station, it may receive an individual call service request or an uplink group call service request, and the specific process thereof is described in detail in the service scheduling method embodiment applied to the idle base station, which is described later.

If the site registration base station confirms that the received third service request information is the group call service request information, executing step S502, and selecting an idle base station in the site to be responsible for voice data coding and decoding;

specifically, after receiving the group call service request information, the site registration base station selects an idle base station from the site where the idle base station is located, and is responsible for encoding and decoding the voice data, specifically performs decoding on the received voice data of the scheduling station and sends the decoded voice data to each terminal included in the group call, and encodes the voice data sent by the terminal included in the received group call and sends the encoded voice data to the access point base station.

S503, sending the selected idle base station information to the access point base station, and enabling the access point base station and the idle base station to directly perform group call service voice data transmission.

Specifically, the station registration base station sends the selected idle base station information, especially the IP address information of the idle base station, to the access point base station, and the access point base station forwards the voice data sent by the scheduling station to the idle base station, and the idle base station decodes the received voice data and sends the decoded voice data to the terminal in the trunking system. When the idle base station receives the voice data sent by the terminal in the cluster system, the idle base station encodes the received voice data and sends the voice data obtained by encoding to the access point base station, and the access point base station forwards the voice data to the dispatching station.

Another embodiment of the present invention also discloses a service scheduling method applied to the idle base station in the cluster system without the central node shown in fig. 1. It can be understood that the method is a service scheduling method applicable to an idle base station in a cluster system without a central node, corresponding to the service scheduling method applicable to the access point base station and the site registration base station in the cluster system without a central node described above.

Further, the idle base station may be an idle base station in a site selected by the site registration base station, or an idle base station selected when the trunking system terminal initiates an uplink service, and it can be understood that, when the access point base station and the site registration base station are the idle base stations in the sites where the access point base station and the site registration base station are located, the access point base station and the site registration base station may also perform the following received service scheduling method in the role of the idle base station while performing the service scheduling method applied to the access point base station and the site registration base station.

In a downlink individual call service request scene, when the access point base station receives individual call service request information sent by the dispatching station, the access point base station broadcasts the individual call request information to the trunking system. Correspondingly, the service scheduling process of the idle base station is as shown in fig. 6:

the idle base station executes the step S601, receives the individual call request information sent by the access point base station and broadcasts the individual call request information;

after broadcasting the individual call request information in the site, the idle base station sends response information to the idle base station when the target terminal of the individual call receives the individual call request and confirms that the individual call request is sent to the idle base station.

When the idle base station receives the response information sent by the target terminal, step S602 is executed to send the information of the idle base station to the access point base station, so that the access point base station establishes a call connection between the idle base station and the dispatching station, so that the idle base station and the dispatching station directly perform voice data transmission;

specifically, the idle base station determines that the target terminal of the call request is within the service range of the idle base station, that is, when receiving the response information sent by the target terminal, sends the information of the idle base station, especially the IP address information of the idle base station, to the access point base station.

Then, the access point base station establishes call connection between the dispatching station and the space base station, that is, establishes a data link between the dispatching station and the idle base station. The voice data transmission can be directly carried out between the dispatching station and the idle base station through the data link, and the idle base station carries out coding and decoding processing on the voice data without forwarding by the access point base station.

When the idle base station receives the individual calling service voice data sent by the dispatching station, executing the step S603, decoding the received individual calling service voice data, and sending the voice data obtained by decoding to the target terminal;

in the downlink group call service scenario, the idle base station is also used for performing coding and decoding processing on the received voice data. When the idle base station receives the group call service voice data sent by the access point base station, step S604 is executed to decode the received group call service voice data, and send the voice data obtained by decoding to the terminal belonging to the group call service in the cluster system without the central node.

The above describes the processing work flow of the idle base station in the cluster system without the central node during the downlink call and the downlink group call. When the idle base station participates in the uplink service scheduling, the idle base station mainly receives an uplink service request initiated by a terminal in the trunking system. Referring to fig. 7, a specific process of the idle base station includes:

s701, receiving fourth service request information sent by a terminal;

and after receiving the fourth service request information sent by the terminal, the idle base station analyzes and identifies the request information, and confirms whether the request information is individual call service request information or group call service request information.

If the received fourth service request message is a call service request message, the idle base station executes step S702, and sends the information of the idle base station to the access point base station, so that the access point base station establishes call connection with the dispatching station for the idle base station, so that the idle base station and the dispatching station directly perform voice data transmission;

specifically, when the idle base station receives the uplink individual call service request information, it sends its own information, especially its own IP address information, to the access point base station. The access point base station establishes call connection for the idle base station and the dispatching station, namely, a voice data transmission link is established. And the idle base station and the dispatching station directly carry out voice data transmission through the voice data transmission link.

When receiving the individual calling service voice data sent by the terminal, executing step S703, encoding the received individual calling service voice data, and sending the voice data obtained by encoding to the dispatching desk;

if the received fourth service request message is a group call service request message and the group call service requires a scheduling station to participate, the idle base station executes step S704 and sends the information of the idle base station to the access point base station;

specifically, if the uplink group call service needs to be participated in by the scheduling station, the group call service data needs to be forwarded by the access point base station of the cluster system without the central node, because only the access point base station has an external address that can be accessed by the scheduling station. Therefore, when the idle base station confirms that the received fourth service request information is the group call service request information and the group call service needs to be participated by the dispatching desk, the idle base station sends self information, especially self IP address information, to the access point base station, so that the access point base station sends the group call voice data to the idle base station.

When the idle base station receives the group call service voice data sent by the terminal, step S705 is executed to send the received group call service voice data to other terminals belonging to the group call service, encode the received group call service voice data, and send the voice data obtained by encoding to the access point base station.

Specifically, when the idle base station receives the group call service voice data sent by the terminal, the group call service voice data is sent to other terminals belonging to the group call, meanwhile, the received group call service voice data is encoded, the voice data obtained through encoding is sent to the access point base station, and the access point base station forwards the voice data to the dispatching station, so that the voice data transmission from the terminal to the dispatching station is realized.

It should be noted that, the foregoing embodiments all describe the voice call service scheduling method in the cluster system without the central node, and similarly, when the cluster system without the central node performs data service, the scheduling method is similar to the foregoing voice service scheduling method, and may be executed by referring to the foregoing embodiments of the present invention, and details of the embodiments of the present invention are not described again.

In another embodiment of the present invention, a cluster system without a central node is disclosed, as shown in fig. 8, the cluster system includes a set number of sites connected via a network, each site including a first number of base stations; any base station of any site has an external address allowing a dispatching station to access, and is used as an access point base station 800 of a cluster system without a central node, and any base station is respectively arranged in other sites and is used as a site registration base station 810;

specifically, the cluster system without the central node disclosed in the embodiment of the present invention is composed of a set number of sites, and each site is connected to a router through a switch and a network. Within each site, a first number of base stations are respectively provided, each base station being previously interconnected. The first number can be flexibly set according to actual requirements. Wherein, any base station under any one of the sites with the set number has an external address allowing the dispatcher station to access, and the base station with the external address can be used as an access point base station of the whole cluster system without the central node and can communicate with the dispatcher station. In the rest sites, any one base station in the sites is respectively set as a site registration base station.

The embodiment of the invention also sets that each dispatching station of the dispatching system respectively registers the information of the dispatching station and the information of the receiving group calling list to the access point base station, and each site registration base station also respectively registers the information of the receiving group calling list to the access point base station;

specifically, referring to fig. 2, each scheduling station of the scheduling system sends scheduling station information, especially scheduling station IP address information and scheduling station group call receiving list information to the access point base station, and each station registration base station sends the group call receiving list information to the access point base station;

after receiving the above information sent by the scheduling station and the site registration base station, the access point base station stores the above information, that is, stores the information of each scheduling station and the received group call list information, and stores the received group call list information of each site registration base station.
