[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all 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.
Fig. 1 is a schematic network architecture of a fire rescue communication system according to the present application.
Referring to fig. 1, the fire rescue communication system 1 includes: small base stations 11a and 11b, fire emergency lamps 12a and 12b, a packet core network server, an eGW server 14, a CPE outdoor station 15, a macro base station 16, an emergency command vehicle 17, a fire helmet 18 worn by a fire fighter, a mobile terminal 19 carried by a trapped person in an emergency situation, and a fire command background 120.
Specifically, the small base station 11a is disposed in the fire emergency lamp 12a, and the small base station 11b is disposed in the fire emergency lamp 12 b. It should be noted that fig. 1 is only a schematic diagram, and in practical application, the number and the positions of the small base station and the fire emergency lamps may be set according to requirements, and are not described herein again.
The packet core network server comprises a packet core network 13b in a public network mode and a packet core network 13a in a private network mode, wherein the packet core network 13b in the public network mode is the core network of an operator. The small cell 11a and the small cell 11b communicate with the eGW server 14 by a power carrier method.
The small cell 11a and the small cell 11b, and the packet core network 13b in the public network mode and the packet core network 13a in the private network mode are connected to the eGW server 14 through a switch (not shown in fig. 1).
When an emergency situation does not occur, the small cell 11a and the small cell 11b are used as an indoor distribution system in a public network mode, and are connected to a packet core network 13b in the public network mode (i.e. a core network of an operator) through the eGW server 14, so as to ensure that an indoor area has ideal signal coverage.
When an emergency situation occurs, the fire command background 120 sends a mode switching request to the eGW server 14, and after receiving the mode switching request, the eGW server switches from the packet core network connected to the public network mode to the packet core network connected to the private network mode, and forwards the mode switching request to the small base station (including the small base station 11a and the small base station 11 b).
After receiving the mode switching request, the small base station reads the working parameters of the private network from the configuration file, completes configuration and then is connected to the packet core network 13a of the private network mode, and the small base station is provided with a working power supply by the fire-fighting emergency lamp in the private network mode. For example, as shown in fig. 1, the small base station 11a is supplied with operating power from a fire emergency lamp 12a, and the small base station 11b is supplied with operating power from a fire emergency lamp 12 b. The private network working parameters include PLMN, Tracking Area Code (TAC) and neighbor cell information.
Compared with the prior art, the power supply of the building is cut off under the emergency situation (such as fire, earthquake, riot, and the like), and the fire-fighting emergency lamp enters the working state to provide illumination, so that the small base station can still be in the working state under the emergency situation by providing the working power supply for the small base station by utilizing the fire-fighting emergency lamp.
In an emergency situation, a firefighter enters a building to monitor the field conditions and perform rescue. In this embodiment, the firefighter wears a fire fighting helmet 18, the fire fighting helmet 18 having a camera for capturing video information and a communication module (neither shown in fig. 1) adapted to communicate with the small cell site in the private network mode to transmit data information (e.g., captured video information). The packet core network server (the packet core network 13a in the private network mode at this time) transmits the video information received by the small base station back to the emergency command vehicle 17 through the CPE outdoor station, the emergency command vehicle 17 is provided with a portable base station (not shown in fig. 1), the portable base station supports CPE data return and video information return at the same time, and the portable base station includes the functions of a core network and a dispatching desk.
Furthermore, the fire rescue communication system of the embodiment can provide reliable private network mode communication for the emergency command vehicle, and can also realize counting, monitoring and positioning of the number of people trapped in the building through a code detection means.
With continued reference to FIG. 1, both the fire fighting helmet 18 worn by the firefighter and the mobile terminal 19 of the trapped person in the public network mode have the International Mobile subscriber identity IMSI, from which the eGW server 14 can distinguish the fire fighting helmet 18 worn by the firefighter from the mobile terminal 19 in the public network mode. In order to not affect the mobile terminal 19 of the trapped person to still communicate in the public network mode, therefore, the eGW server 14 will reject the attach request or tracking area update request initiated by the mobile terminal 19 in the public network mode.
Specifically, the IMSI of the fire helmet 18 worn by the fire fighter may be set as a white list user and the other terminals (e.g., the IMSI of the mobile terminal 19 in the public network mode) may be set as blacklist users within the eGW server 14. When a certain terminal (fire helmet 18 or mobile terminal 19) initiates an attachment request or a tracking area update request, the determination is performed according to the IMSI of the terminal, if the terminal is a white list user, the attachment request or the tracking area update request initiated by the terminal is received, and if the terminal is not a white list user, the attachment request or the tracking area update request initiated by the terminal is refused to be received.
Further, in order to monitor and locate the number and position of people trapped in the building, the broadcasting strategy of the small cell needs to meet the following requirements:
1) public land mobile networks PLMN broadcasted by the small base stations (including the small base station 11a and the small base station 11b shown in fig. 1) include a public network mode PLMN and a private network mode PLMN, so that a mobile terminal in the public network mode is adapted to access each small base station in the private network mode.
In order to enable the eGW server 14 to capture the mobile terminals in the coverage area of each small cell in the access private network mode, when the small cell in the private network mode broadcasts the system message, the Public Land Mobile Network (PLMN) in the public network mode and the PLMN in the private network mode are broadcasted, the PLMN in the public network mode is the master PLMN during broadcasting, and the PLMN in the private network mode is the slave PLMN, so that the mobile terminal 19 in the public network mode can receive the PLMN in the public network mode broadcasted by the small cell and access the small cell. It should be noted that in this case, the reason for accessing the small cell by the mobile terminal 19 is to make the eGW server capable of grabbing, but not attaching to the coverage area of the small cell, and the mobile terminal 19 still operates in the public network mode.
2) The rotation ranges of tracking area codes TAC of all small base stations are different, and no intersection exists between the TAC of all small base stations and the TAC of the macro base station.
Specifically, on the one hand, the rotation ranges of the tracking area codes TAC of the respective small base stations are different. Therefore, it can be avoided that two small base stations have the same TAC, so that when the mobile terminal 19 of the trapped person moves from the coverage Area of one small base station to the coverage Area of another small base station, a Tracking Area Update (TAU) process is not performed, and the eGW server 14 cannot sense the mobile terminal 19.
On the other hand, the TAC of the small base station needs to skip the TAC of the macro base station 16 in the public network mode in the rotation process, which is to avoid influencing the TAC of the macro base station accessed by the mobile terminal 19 in the public network mode, so as to influence the communication of the mobile terminal in the public network mode.
Under the condition that the broadcast policy requirements of the two small base stations are met, periodically (the period can be determined according to the period of TAC rotation of each small base station) capturing access information of the mobile terminal in the coverage area of each small base station (for example, the small base station 11a and the small base station 11b) in the access private network mode through the eGW server 14, and sending the access information of the mobile terminal to the fire command background 120 to realize monitoring and positioning of the mobile terminal 19. The access information includes an IMSI of the mobile terminal, a Received Signal Strength Indication (RSSI), a time for accessing the small cell, and an access number of the small cell (e.g., the small cell 11a or the small cell 11 b).
In this embodiment, a communication system applicable to the fire rescue communication system is Long Term Evolution (LTE), and correspondingly, the small base station is an LTE small base station, and the macro base station is an LTE macro base station. In other embodiments, the fire rescue communication system provided by the present application may also be applicable to other communication systems, and accordingly, the small base station and the macro base station are base stations applicable to the communication system and are not described herein again.
Based on the fire rescue communication system, the application also provides a communication method which is applied to the small base station arranged in the fire emergency lamp in the fire rescue communication system.
