With the continuous development of wireless communication technology, trunking communication technology develops from an analog system to a narrowband digital trunking system, and with the increasing demand of industrial users on wireless broadband, the trunking communication technology develops from a simple voice service to a digital trunking communication system represented by eLTE.
At present, the field of domestic public security industry widely adopts Police Digital Trunking system (PDT). Due to the fact that the PDT system cannot meet the requirement of broadband business which is more and more urgent in public security, in order to protect the existing investment of PDT and maintain the advantage of PDT voice in coverage, the coexistence of PDT and the lte system is an unblocked trend, and under the great trend, a PDT/lte fusion system and a PDT/lte dual-mode terminal can be produced. Fig. 1 is a public security broadband wireless multimedia trunking system architecture diagram.
The inventor discovers that in the process of implementing the invention: the PDT system has the problems of high upgrading cost of terminal version and inconsistent data between the network side and the terminal, and the specific reasons are as follows:
in the PDT system, if a terminal has a new function introduction or software finds that a bug is solved, the terminal version needs to be upgraded, one terminal version is large, and the terminal version is dozens of megabytes or hundreds of megabytes, and as the PDT bandwidth is narrow, the PDT terminal is required to be recovered for unified upgrade or the terminals are upgraded one by one at the near end, so that time and labor are wasted, and the upgrade cost is too high; similarly, because PDT bandwidth is narrow and limited air interface bandwidth is reserved for PDT cluster service as much as possible, user group configuration and user contact information on the network side cannot be synchronized to the terminal, resulting in inconsistent data between the network side and the terminal.
Under the wide-narrow fusion system, when the dual-mode terminal is in the PDT network, if the terminal version upgrade or the big data push is needed, there is the above problem due to the narrow PDT bandwidth.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 2 is a schematic flow diagram of a method according to an embodiment of the present invention, and as shown in fig. 2, the data pushing method under the wideband-narrowband fusion implemented in the embodiment mainly includes:
The difference between the step and the existing system is that the narrowband convergence core network needs to record the network where the narrowband dual-mode terminal is registered, so that the core network can know the network where the narrowband dual-mode terminal is located in the subsequent process, and further can execute different processing modes according to the network where the narrowband dual-mode terminal is located when version upgrading or big data pushing needs to be carried out on the narrowband dual-mode terminal, so as to overcome many problems caused by narrow bandwidth of the narrowband network.
In practical application, the fusion of the narrow band and the wide band may be a fusion of a PDT network and an LTE network, that is, the narrow band network is the PDT network, and the wide band network is the LTE network, but is not limited thereto.
The specific registration method of the terminal in this step is similar to that of the existing system, and the specific registration timing is not described herein again when the dual-mode terminal is powered on or network is switched.
Here, when version upgrade or big data push needs to be performed on the narrowband and wideband dual-mode terminal, the narrowband and wideband convergence network management device needs to notify the requirement to the narrowband and wideband convergence core network, and the core network is responsible for controlling the version upgrade or big data push of the terminal, so as to overcome the problem caused by the narrower bandwidth of the narrowband network.
And 203, when the narrowband convergence core network receives the instruction, according to the network currently registered by the narrowband dual-mode terminal and according to the principle of performing version upgrade or big data push only when the terminal is in the broadband network, sending corresponding version upgrade data or big data to be pushed to the narrowband dual-mode terminal.
Here, according to the network in which the narrowband and wideband dual-mode terminal is currently registered, and according to the principle that version upgrading or big data pushing is performed only when the terminal is in the wideband network, corresponding version upgrading data or big data to be pushed is sent to the narrowband and wideband dual-mode terminal, so that the narrowband and wideband fusion core network can ensure that version upgrading or big data pushing is performed only when the terminal is in the wideband network according to the network in which the terminal is registered, and avoid sending a large amount of data to the terminal under the narrowband network, thereby avoiding the influence of version upgrading or big data pushing on the narrowband network while realizing terminal version upgrading or big data pushing.
Preferably, the following method may be adopted to send the corresponding version upgrade data or the big data to be pushed to the narrowband dual-mode terminal according to the network currently registered by the narrowband dual-mode terminal and according to the principle that the version upgrade or the big data push is only performed when the terminal is in the broadband network:
and if the network currently registered by the broadband-narrowband dual-mode terminal is a broadband network, informing the broadband-narrowband fusion network management equipment to send corresponding terminal version upgrading data or big data to be pushed to the broadband-narrowband dual-mode terminal.
Here, for a narrowband dual-mode terminal in a broadband network, because there is no problem of narrow network bandwidth, corresponding terminal version upgrade data or large data to be pushed may be directly sent to the narrowband dual-mode terminal.
And if the network currently registered by the broadband and narrowband dual-mode terminal is a narrowband network, triggering the broadband and narrowband dual-mode terminal to switch to a broadband network, and then sending corresponding version upgrading data or big data to be pushed to the broadband and narrowband dual-mode terminal.
Here, for a narrowband dual-mode terminal in a narrowband network, before version upgrade or big data push is performed, it needs to trigger the terminal to switch to a broadband network first, so as to avoid the influence on the narrowband network.
Further, the method may employ the following steps to trigger the narrowband dual-mode terminal to switch to the broadband network:
step a1, the narrowband and wideband fusion core network informs the narrowband and wideband fusion network management equipment that the narrowband and wideband dual-mode terminal is currently in the narrowband network, and sends a terminal version upgrade or big data push instruction to the narrowband and wideband dual-mode terminal according to the state of the narrowband and wideband dual-mode terminal.
Preferably, in order to reduce the air interface overhead of the narrowband network, different modes may be adopted to send a terminal version upgrade or a big data push instruction to the narrowband dual-mode terminal according to the state of the narrowband dual-mode terminal, specifically as follows:
if the broadband/narrowband dual-mode terminal is in service, sending a narrowband downlink associated channel signaling to the broadband/narrowband dual-mode terminal, wherein the narrowband downlink associated channel signaling carries the terminal version upgrading or big data push indication;
and if the broadband and narrowband dual-mode terminal is in an idle state, sending a state short message to the broadband and narrowband dual-mode terminal, wherein the state short message carries a terminal version upgrading or big data pushing indication.
Step a2, after receiving the notification, the broadband and narrowband convergence network management device starts a waiting-to-send timer.
The waiting sending timer is used for limiting the time length for the network management equipment to wait for the switching of the broadband and narrowband dual-mode terminal to the broadband network. In practical applications, a person skilled in the art can set the duration of the waiting-to-send timer according to practical needs.
A3, the terminal sends the corresponding terminal version upgrade or big data push response message to the core network according to the received terminal version upgrade or big data push instruction, and executes the process of switching to the broadband network; and after the switching is finished, sending a terminal version upgrading or big data pushing response message to the broadband and narrowband fusion network management equipment through the broadband and narrowband fusion core network.
Preferably, the mode of the narrowband and wideband dual-mode terminal sending the corresponding terminal version upgrade or big data push response message to the narrowband and wideband fusion core network is consistent with the mode of the narrowband and wideband fusion core network sending the terminal version upgrade or big data push indication, which is specifically as follows:
when the terminal version upgrading or big data push indication is carried by the narrow-band downlink associated channel signaling, the wide-band and narrow-band dual-mode terminal sends narrow-band uplink associated channel signaling to the wide-band and narrow-band fusion core network, and the narrow-band uplink associated channel signaling carries the terminal version upgrading or big data push response message.
And when the terminal version upgrading or big data push indication is carried by the state short message, the broadband-narrowband dual-mode terminal sends the state short message carrying the terminal version upgrading or big data push response message to the broadband-narrowband fusion core network.
Step a2, if the narrowband convergence network management device receives the terminal version upgrade or big data push response message before the waiting sending timer is not overtime, sending the corresponding version upgrade data or big data to be pushed to the narrowband dual-mode terminal.
If the terminal version upgrade or big data push response message has not been received when the sending timer is waited for time out, the broadband and narrowband convergence network management device may return to step 202 to re-execute the above process to complete the corresponding terminal version upgrade or big data push.
By using the method, the terminal version upgrading or big data pushing under the wide-narrow band fusion scene can be realized, and when the terminal version upgrading or big data pushing is required, many problems caused by narrow bandwidth of the narrow-band network can be overcome, and the normal operation of the narrow-band network cannot be influenced.
Fig. 3 shows a specific flowchart of implementing the above method embodiment in a scenario of PDT and LTE network convergence, and it can be seen from the diagram that a dual-mode terminal registers in a PDT/LTE convergence system first, when a terminal version needs to be upgraded or big data needs to be pushed to the terminal, a network side determines a network where the terminal is currently located, and if the terminal is currently located in the PDT network, the network side notifies the terminal to switch to the LTE network for data downloading, so that the terminal version upgrade or big data pushing can be implemented while avoiding an impact on the PDT network performance.
Fig. 4 is a data push system under the wideband-narrowband fusion corresponding to the above method embodiment, and as shown in fig. 4, the system mainly includes a wideband-narrowband fusion core network, a wideband-narrowband fusion network management device, a wideband-narrowband fusion base station, and a wideband-narrowband dual-mode terminal.
