Detailed Description
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 terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic network architecture diagram of a trunking communication system in the prior art, and as shown in fig. 1, the trunking communication system includes: the system comprises a terminal, a private network base station, a private network core network and a cluster server. The terminal can be specifically a command scheduling terminal and a data transmission terminal, and comprises a handheld terminal, a fixed terminal, a vehicle-mounted terminal, a desktop terminal, a network card or a wireless monitoring camera terminal and other equipment; the private network base station is a device for accessing the terminal to a communication network; the private network core network is responsible for network side mobility management of the terminal, S1 link management, and unified exchange control and transmission of service data; the cluster server is responsible for the coordinated scheduling and call control of the whole cluster system.
In the prior art, after a link between a private network base station and a private network core network is interrupted, the private network base station and a terminal enter a failure weakening mode, and in this mode, the private network base station implements a partial session control function of the private network core network, so that the terminal within the coverage of the private network base station can access the private network base station, and thus partial services can be performed between the terminals within the coverage of the private network base station, for example: a group service or a single call service. And when the fault is recovered, the private network base station exits the fault weakening mode and recovers to a normal cluster scene.
However, in the above prior art, when the private network base station and the terminal enter the failure weakening mode, the service of the terminal is limited, and the terminal within the coverage area of the private network base station cannot communicate with the terminal outside the station, which affects the user experience.
In order to solve the above problem, an embodiment of the present invention provides a trunking communication method, which is suitable for a terminal supporting a public network mode and a private network mode. Fig. 2 is a network architecture diagram of a trunking communication system according to an embodiment of the present invention, and as shown in fig. 2, a terminal may be communicatively connected to a trunking server through a private network base station and a private network core network, and may also be communicatively connected to the trunking server through a public network base station and a public network core network.
Generally, a private network can provide better service quality for a terminal, and therefore, in the embodiment of the invention, the terminal works in a private network mode under a normal condition, that is, the terminal performs data interaction with a cluster server through a private network base station and a private network core network. When a link between the private network base station and the private network core network fails, the terminal is switched to a public network mode, namely, the terminal performs data interaction with the cluster server through the public network base station and the public network core network. That is to say, even after a link between the private network base station and the private network core network fails, the terminal can also perform the trunking service through the public network base station and the public network core network, so that the degree of influence on the terminal service is reduced, the problem that the terminal service is limited due to the fact that the terminal base station enters a failure weakening mode in the prior art is solved, and the user experience is improved.
It should be noted that, the public network base station and the private network base station in the embodiment of the present invention both refer to a device that accesses a terminal to a communication network, where the public network base station accesses the terminal to a public communication network, and the private network base station accesses the terminal to a private communication network. The public communication network and the private communication network may be a Global System for Mobile communications (GSM) network or a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, a Long Term Evolution (Long Term Evolution, LTE) network, or a future 5G network.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a schematic flowchart of a trunking communication method provided in an embodiment of the present invention, where the method of this embodiment may be executed by the terminal in fig. 2.
As shown in fig. 3, the method of the present embodiment includes:
s301: and detecting whether the private network base station enters a failure weakening mode, if so, executing S302.
Specifically, under normal communication conditions, since the private network can provide better service quality than the public network, the terminal is enabled by default in the private network mode, that is, the terminal resides in a private network base station.
The failure weakening mode is used for indicating that the private network base station cannot be in communication connection with the private network core network. Specifically, the private network base station is responsible for monitoring the state of a communication link between the private network base station and a private network core network. When communication faults between the private network base station and the private network core network are monitored, the private network base station enters a fault weakening mode. Wherein, the communication link state failure includes but is not limited to: core network device failure, physical interruption of the S1 interface, etc.
When the private network base station monitors the communication fault between the private network base station and the private network core network, the private network base station can clear all services under the base station because the terminal within the coverage range of the private network base station can not reside in the private network core network any more.
It should be noted that, in the embodiment of the present invention, the implementation manner that the private network base station enters the failure weakening mode may be implemented by using the prior art, and the embodiment of the present invention is not limited in particular. In an optional implementation manner, the private network base station further includes a session control module based on the original base station structure. After the private network base station enters the failure weakening mode, the private network base station not only keeps the original function of the base station, but also starts the function of the session control module.
The session control module is responsible for taking over and processing an attachment flow of a terminal in a coverage area of a private network base station after a communication fault between the private network base station and a private network core network, and specifically comprises the following steps: the method comprises the following steps of call service initiated by a terminal, terminal information management, terminal access control, Non-access stratum (NAS) signaling processing, Session Initiation Protocol (SIP) signaling processing, terminal mobility management, service bearing resource control, paging control, NAS security, terminal authentication, data encryption and other functions. Meanwhile, the session control module is also responsible for controlling the establishment and release of the cluster service bearer between the private network base station and the terminal.
It can be understood that when the private network base station is in the normal working mode, the session control module does not process any data any more, and the above-mentioned function of the session control module is enabled only after the private network base station enters the failure weakening mode.
In this embodiment, the terminal may monitor the operating mode of the private network base station, so as to determine whether the private network base station operates in the normal mode or the failure weakening mode. In a specific implementation process, the terminal may detect the working mode of the private network base station in multiple ways, which is not specifically limited in the embodiment of the present invention.
In an optional implementation manner, the base station may carry a field for indicating the operation mode in the system message, that is, the terminal determines whether the private network base station enters the failure weakening mode according to the received system message.
In another optional implementation, the base station may send the operation mode change message to the terminal when the operation mode is changed, that is, the terminal determines whether the base station enters the failure weakening mode by detecting whether the operation mode change message is received.
It can be understood that, if the terminal detects that the private network base station enters the failure weakening mode, the subsequent process of this embodiment is continuously executed to solve the problem in the prior art that the service of the terminal is limited due to the private network base station entering the failure weakening mode. If the terminal does not detect that the private network base station enters the failure weakening mode, the embodiment is ended.
S302: and judging whether the terminal supports the public network mode, if so, executing S303, and if not, executing S304.
Specifically, a terminal in the trunking communication network usually supports a private network mode, and performs trunking service in the private network mode. With the development of terminal technologies, more and more terminals start to support both the private network mode and the public network mode.
Therefore, in this embodiment, after the terminal detects that the private network base station enters the failure weakening mode, it is determined whether the terminal supports the public network mode. If the terminal supports the public network mode, the terminal can be switched to the public network mode, so that the terminal does not need to enter a failure weakening mode, and the influence on the terminal service is avoided.
The determination of whether the terminal supports the public network mode may be implemented in various ways, and the embodiment of the present invention is not limited in particular. In an optional implementation manner, whether the terminal supports the public network mode may be determined according to the capability information of the terminal.
S303: and switching the terminal to a public network mode, and attaching the terminal to a public network core network through a public network base station so that the terminal performs the trunking service through the public network.
Specifically, if the terminal supports the public network mode, the terminal is switched to the public network mode, so that the terminal can perform data interaction with the cluster server through the public network base station and the public network core network. It should be noted that, the process of attaching the terminal to the core network of the public network through the public network base station belongs to the prior art, and may be implemented by using the prior art, which is not described in detail in the embodiments of the present invention.
Two possible cases are specifically included here. In the first case, the terminal supports the standby in the public network mode and the private network mode at the same time, and in this case, if the terminal is already in the standby state in the public network, the terminal only needs to switch the working mode to the public network mode; if the terminal has not accessed the public network, the working mode is switched to the public network mode, and then the terminal needs to be attached to a core network of the public network through a base station of the public network. In the second case, the terminal only supports standby in a public network mode or a private network mode, in which case, the terminal needs to switch the working mode to the public network mode and attach the terminal to a core network of the public network through a base station of the public network.
After the terminal enters the public network mode, the cluster service can be carried out through the public network. Specifically, the terminal may perform cluster communication with terminals in the public network and/or terminals in the private network. In an alternative embodiment, the terminals in the public network mode may perform the trunking service through POC (push to talk Over Cellular). POC is a mobile communication service based on a network, and provides a half-duplex communication method for users. On the user terminal supporting the POC, the user can make a one-to-one call or a group call with a similar interphone function in a wider range among groups.
S304: and clearing all services of the terminal, and attaching the terminal to the private network base station so that the terminal performs trunking services in the private network base station.
Specifically, if the terminal does not support the public network mode, the failure weakening process in the prior art is executed. Namely, the terminal enters a failure weakening mode and clears all services; because the private network base station enters the failure weakening mode, the terminal can be attached to the private network base station, and single call service or trunking service is carried out in the base station. It should be noted that, the process of attaching the terminal to the private network base station in the failure weakening mode belongs to the prior art, and may be implemented by using the prior art, which is not described in detail in the embodiments of the present invention.
According to the trunking communication method provided by the embodiment of the invention, after a terminal detects that a private network base station enters a failure weakening mode, whether the terminal supports a public network mode or not is judged, and if the terminal supports the public network mode, the terminal is switched to the public network mode so as to enable the terminal to perform trunking service through the public network base station; therefore, even after the private network base station enters the failure weakening mode, the terminal can also perform the cluster service through the public network, so that the influence degree on the terminal service is reduced, the problem of limited terminal service caused by the fact that the terminal base station enters the failure weakening mode in the prior art is solved, and the user experience is improved.
The following describes in detail the interaction process in the case where the terminal supports the public network mode and the case where the terminal does not support the public network mode, with reference to two specific embodiments.
Fig. 4 is a first interaction schematic diagram of the trunking communication method provided in the embodiment of the present invention, and this embodiment illustrates an interaction process in a case where a terminal supports a public network mode. As shown in fig. 4, the method of this embodiment includes:
s401: and the terminal receives the system message sent by the private network base station.
S402: and determining that the private network base station enters a failure weakening mode according to the system message.
The system message may be a MIB (masterinformation block) system message, or may also be an SIB (systemlnformationblocks) system message, which is not limited in the embodiments of the present invention. In an optional implementation manner, the private network base station may carry a preset cell in a system message systemlnformationblocktypereporting, which is used to instruct the private network base station to enter a failure weakening mode.
S403: and acquiring the capability information of the terminal, and determining that the terminal supports a public network mode according to the capability information.
In specific implementation, whether the terminal supports the public network mode or not can be used as one capability information of the terminal, the capability information can be stored in a capability information list of the terminal, and whether the terminal supports the public network mode or not can be determined by inquiring the capability information list of the terminal.
S404: and switching the terminal to a public network mode.
S405: and attaching the terminal to a core network of the public network through a public network base station so that the terminal performs the trunking service through the public network.
The embodiments of S401 to S405 in this embodiment are similar to the embodiment shown in fig. 3, and are not described herein again.
Fig. 5 is a second interaction schematic diagram of the trunking communication method provided in the embodiment of the present invention, and this embodiment illustrates an interaction process in a case that a terminal does not support a public network mode. As shown in fig. 5, the method of this embodiment includes:
s501: and the terminal receives the system message sent by the private network base station.
S502: and determining that the private network base station enters a failure weakening mode according to the system message.
S503: and acquiring the capability information of the terminal, and determining that the terminal does not support a public network mode according to the capability information.
S504: and clearing all services of the terminal.
S505: and attaching the terminal to the private network base station so that the terminal performs trunking service in the private network base station.
The embodiments of S501 to S505 in this embodiment are similar to the embodiments shown in fig. 3 and fig. 4, and are not described herein again.
On the basis of the above embodiment, when the terminal is in the public network mode, it may also be detected whether the private network base station exits the failure weakening mode, and if the private network base station exits the failure weakening mode, the private network base station is switched to the private network mode to improve the service quality of the trunking service.
Here, the following two cases may be included according to the terminal capability. In the first case, the terminal supports the standby in the private network and the public network at the same time, and in this case, when the terminal is in the public network mode, the terminal can still receive the system message of the private network base station in real time, so that whether the private network base station exits the failure weakening mode can be judged by receiving the system message. In a second case, the terminal only supports public network standby or private network standby, and in this case, when the terminal is in the public network mode, the terminal cannot receive the system message of the private network base station in real time.
The following describes in detail an interactive process of switching the terminal back to the private network mode in conjunction with a specific embodiment.
Fig. 6 is a third interaction schematic diagram of the trunking communication method provided in the embodiment of the present invention, as shown in fig. 6, the method of the embodiment includes:
s601: and the terminal receives the system message sent by the private network base station.
S602: and determining that the private network base station exits the failure weakening mode according to the system message.
S603: and switching the terminal to a private network mode.
S604: and attaching the terminal to a private network core network through the private network base station so that the terminal performs a trunking service through the private network.
It can be understood that the private network can provide better service quality, and when the base station of the private network exits the failure weakening mode, the terminal can switch to the private network to perform the trunking service in the private network, thereby ensuring to enjoy better service quality.
The detailed description of the present embodiment, similar to the above embodiments, will not be repeated herein.
