A group call processing method, a communication device, a storage medium and a communication system

Abstract

The application provides a group call processing method, a communication device, a storage medium and a communication system. In the case that a transit device receives group call link control signaling from an IP network, the transit device periodically broadcasts idle signaling carrying a group call identifier to an air interface. A terminal device informs the transit device whether the group call information corresponding to the group call identifier needs to be forwarded by replying to a group call response. In the case that the terminal device does not need to receive the group call information corresponding to the group call identifier, the transit device does not forward the group call information corresponding to the group call identifier, thereby avoiding waste of air interface channel resources and effectively improving the utilization rate of air interface channel resources.

[0073] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0074] The inventor finds that the prior art mentioned in the background art has the problem of wasting channel resources. There are two solutions. One solution is to configure IP interconnection access management to limit whether the local transit device receives a specific group call forwarded by other transit devices. Another solution is to configure a specified IP interconnection time slot to limit the local transit device to receive only a group call in a specific time slot forwarded by other transit devices. The above two prior arts can solve the problem of wasting channel resources to some extent, but they need to write frequency configuration in advance, lack flexibility, and cannot meet the needs of some customer scenarios.

[0075] On this basis, the application provides a group call processing method. When the transit device receives group call link control signaling from an IP network, it periodically broadcasts idle signaling carrying a group call identifier to the air interface, so that the terminal notifies the transit device whether it needs to forward group call information corresponding to the group call identifier by replying to the group call response. This avoids the transit device forwarding group call information corresponding to the group call identifier when the terminal does not need to receive the group call information. This not only solves the problem of wasting air interface channel resources, but also can be flexibly applied to various scenarios, effectively improving the utilization rate of air interface channel resources.

[0076] Specifically, please refer to Figure 1 The embodiment discloses a group call processing method applied to a transit device, which can be but is not limited to a base station or a transit station. The group call processing method comprises the following steps:

[0077] S101: In the case of receiving group call link control signaling from an IP network, parse the group call link control signaling to obtain a group call identifier.

[0078] The above-mentioned link control signaling is LC (Link Control) signaling, which carries a group call identifier. The group call identifier uniquely represents a group call.

[0079] The group call link control signaling from the IP network can be group call link control signaling sent by a terminal device hung under other transit devices in an IP interconnection system.

[0080] S102: Periodically broadcast idle signaling carrying a group call identifier to the air interface.

[0081] The idle signaling is IDLE signaling. One format of the idle signaling is as follows Figure 2As shown in the table, the format includes: a protection flag (English full name: Protect Flag, English abbreviation: PF), a reserved field (English full name: Reserved, English abbreviation: R), a control signaling block opcode (English full name: Control Signalling Block Opcode, English abbreviation: CSBKO), a group call broadcast opcode (English full name: GROUPCALL_BROADCAST), a feature set ID (English full name: Feature Set ID, English abbreviation: FID), and a target address (English full name: Target Address).

[0082] S103: If the reply signaling of the terminal device is received, stop periodically broadcasting the idle signaling carrying the group call identifier to the air interface, and forward the group call information corresponding to the group call identifier to the air interface.

[0083] The terminal device under the transit device parses the broadcasted group call identifier from the idle signaling, and if it needs to receive the group call information corresponding to the group call identifier, it sends a reply signaling CSBK (Control Signalling Block) to the transit device in the corresponding next time slot, and if it does not need to receive the group call information corresponding to the group call identifier, it does not send a reply signaling to the transit device.

[0084] One format of the reply signaling is as shown in the table Figure 3 As shown in the table, the format includes: a protection flag (English full name: Protect Flag, English abbreviation: PF), a reserved field (English full name: Reserved, English abbreviation: R), a control signaling block opcode (English full name: Control Signalling Block Opcode, English abbreviation: CSBKO), a group call broadcast opcode (English full name: GROUPCALL_BROADCAST), a feature set ID (English full name: Feature Set ID, English abbreviation: FID), and a target address (English full name: Target Address).

[0085] S104: If the reply signaling of the terminal device is not received, continue to periodically broadcast the idle signaling carrying the group call identifier to the air interface.

[0086] As shown in the table Figure 4 As an example of the use scenario shown in the table, the terminal device sends voice service through the air interface, and the transit device can forward it to other transit devices through a wired network after receiving it. The transit device sends the voice service to the terminal device under it through the air interface.

[0087] The terminal devices under the transit device 1 and the transit device 2 are all mounted with the terminal devices of the talk group G100, and the terminal devices under the transit device 3 are mounted with the terminal devices of the talk group G200. When the terminal devices under the transit device 2 initiate the G100 call, all the transit devices in the prior art do not check whether the currently mounted terminal devices support the group call, and all the transit devices will forward the group call in the air interface. In the technical solution disclosed in the embodiment, when the G100 group call is received, the transit device 3 will periodically broadcast the idle signaling carrying the G100 in the air interface, so that the terminal devices notify the transit device 3 whether the G100 group call information needs to be forwarded by replying the group call response, and the transit device 3 forwards the group call G100 when the reply signaling is received, and does not forward the group call G100 if the reply signaling is not received, thereby avoiding the waste of the air interface channel resources caused by unnecessary occupation of the air interface channel resources, and effectively improving the utilization rate of the air interface channel resources.

[0088] Further, in the case that the transit device does not receive the reply signaling replied by the terminal device, and receives another group call link control signaling from the IP network, the group call link control signaling is parsed to obtain another group call identifier, and then the idle signaling carrying the above group call identifier and the idle signaling carrying another group call identifier are cyclically switched and broadcast in the air interface. Please refer to Figure 5 For example, in the case that the transit device 1 receives the G100 link control signaling sent by the transit device 2 and the G200 link control signaling sent by the transit device 3, in the stage a, the transit device 1 cyclically switches and broadcasts the G100 idle signaling and the G200 idle signaling in the air interface, that is, the G100 idle signaling is broadcasted, then the G200 idle signaling is broadcasted, and then the G100 idle signaling is broadcasted, and the cycle is repeated until the reply signaling sent by the terminal device is received to jump to the stage b. After the reply signaling sent by the terminal device is received, the transit device 1 parses the reply signaling to obtain the group call identifier G100 responded by the terminal device, and then stops cyclically switching and broadcasting the idle signaling carrying the above group call identifier and the idle signaling carrying another group call identifier in the air interface, and forwards the group call information corresponding to the group call identifier G100 responded by the terminal device in the air interface. When the group call G100 ends, the stage jumps to the stage c, the transit device 2 no longer forwards the group call information corresponding to the G100 in the transit device 1, and the transit device 1 also does not forward the group call information corresponding to the G100 in the air interface, and the transit device 1 starts to broadcast the G200 idle signaling in the air interface.

[0089] Further, in the case that the transit device receives the termination signaling (English full name: Link Control Terminator, English abbreviation: LC_Terminator) carrying the group call identifier from the IP network, the transit device enters the channel holding state.

[0090] After entering the channel holding state, the channel holding timeout enters the dormant state. Specifically, after entering the channel holding state, it is determined whether the duration of entering the channel holding state reaches a pre-set threshold, if yes, the dormant state is entered, if not, it is determined whether the group call link control signaling from the IP network is received during this period, if the group call link control signaling from the IP network is received, the step S101 is executed, if the group call link control signaling from the IP network is not received, the channel holding state is continued.

[0091] Referring to Figure 6 The embodiment corresponds to disclose a kind of group call processing method applied to terminal equipment, and terminal equipment can be intercom etc.Moving terminal equipment, the group call processing method specifically includes the following steps:

[0092] S201: in the case of receiving the idle signaling carrying group call identification periodically broadcasted by transit equipment, determine whether it needs to receive group call information corresponding to group call identification.

[0093] Whether it needs to receive group call information corresponding to group call identification can be determined by manual operation terminal equipment, and whether it needs to receive group call information corresponding to group call identification can also be automatically determined by pre-set corresponding relationship between terminal equipment and group call identification.

[0094] S202: if it needs to receive group call information corresponding to group call identification, send response signaling to transit equipment, so that transit equipment stops periodically broadcasting idle signaling carrying group call identification to air interface, and forwards group call information corresponding to group call identification to air interface.

[0095] S203: receive group call information corresponding to group call identification.

[0096] S204: if it does not need to receive group call information corresponding to group call identification, do not send response signaling to transit equipment, and transit equipment continues to periodically broadcast idle signaling carrying group call identification to air interface.

[0097] Further, in roaming scenario, with Figure 7As shown in the scenario, two terminal devices are originally mounted under the transit device 1, and the two terminal devices receive the G100 group call information sent by the transit device 2 under the transit device 1. When one of the terminal devices roams from the transit device 1 to the transit device 3, if the transit device 3 is forwarding the G100 group call information, the roaming terminal device can continue to receive the G100 group call information under the transit device 3. If the transit device 3 is periodically sending the idle signaling carrying the G100, the roaming terminal device sends the response signaling to the transit device 3, so that the transit device 3 stops periodically broadcasting the idle signaling carrying the G100 to the air interface and forwards the G100 group call information to the air interface, and the roaming terminal device can continue to receive the G100 group call information under the transit device 3.

[0098] The group call processing method disclosed in the embodiment is that, in the case of receiving the group call link control signaling from the IP network, the transit device periodically broadcasts the idle signaling carrying the group call identifier to the air interface, and the terminal notifies the transit device whether the group call information corresponding to the group call identifier needs to be forwarded by replying the group call response, so as to avoid the waste of air interface channel resources caused by the transit device forwarding the group call information corresponding to the group call identifier in the case that the terminal does not need to receive the group call information corresponding to the group call identifier, thereby effectively improving the utilization rate of the air interface channel resources.

After receiving the voice link control signaling with group call identifier G100, relay devices 2 and 3 periodically broadcast idle signaling with group call identifier G100 to the air interface. Since terminal device 2 under relay device 2 receives G100, it sends an acknowledgment signaling carrying G100 to relay device 2. Relay device 2 then forwards the voice A-frame to voice F-frame signaling sent by terminal device 1 through relay device 1 to terminal device 2 until the link control termination signaling. Since terminal device 3 under relay device 3 receives G200, it does not send any acknowledgment signaling to relay device 3, and relay device 3 continues to periodically broadcast idle signaling with group call identifier G100.

[0148] This embodiment discloses a communication system in which a relay device, upon receiving a group call link control signaling from an IP network, periodically broadcasts idle signaling carrying a group call identifier to the air interface. The terminal, by replying with a group call response, notifies the relay device whether it needs to forward the group call information corresponding to the group call identifier. This avoids the relay device forwarding the group call information corresponding to the group call identifier when the terminal does not need to receive it, thus preventing the waste of air interface channel resources and effectively improving the utilization rate of air interface channel resources.
