Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a signal measurement method and device.
Background
Broadband Trunking Communication (Btrunc) is a Long Term Evolution (LTE) based private network broadband Trunking system standard established by the broadband Trunking industry alliance organization. The broadband trunking communication mainly aims at broadband trunking services such as multicast service voice, multicast service video and multimedia multicast service scheduling, has the characteristics of flexible bandwidth, high spectrum efficiency, low time delay and high reliability, and can meet the requirements of professional users on multicast service voice, broadband data, emergency command scheduling and the like.
The broadband trunking terminal can be divided into two modes according to different network channels carried by the broadband trunking terminal. One is a private network mode, and services are carried on a private network through a Btrunc network. The other is a public network mode, and services are carried on a public network by means of public network resources (such as 3G/4G, WIFI and the like) of an operator network. The cluster terminal capable of supporting the two modes at the same time is called a convergence terminal. A trunking terminal that supports only one of the above modes at the same time is called a single-mode terminal.
Since the private network mode and the public network mode use different network coverage, for a single mode terminal, a private network signal and a public network signal cannot be measured simultaneously. For example, when a single mode terminal is receiving a service in a public network, if a private network signal needs to be measured, the reception of the service needs to be stopped to measure the private network signal. However, the private network service server is still continuously transmitting data, which causes the single mode terminal to lose data during the measurement of the private network signal, and abnormal phenomena such as word loss and interruption of voice service, screen splash of video service, and the like occur, thereby reducing the service quality.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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 an architecture diagram of a communication system according to the present invention. As shown in fig. 1, the communication system may include: the terminal device 100, the private network server 200, the private network base station 300, the private network core network device 400, the public network base station 500, and the public network core network device 600. The private network server 200, the private network base station 300, and the private network core network device 400 are communication devices in a private network. The public network base station 500 and the public network core network device 600 are communication devices in a public network. The public network refers to a public communication network provided by a network operator, for example, a Time Division-Synchronous code Division Multiple Access (TD-SCDMA) network, a Long Term Evolution (LTE) network, a 5G network, and the like. The private network corresponds to a public network, e.g., a Btrunc network. The terminal device 100 may communicate with the private network server 200 through the private network base station 300 and the private network core network device 400 in the private network. The terminal device 100 may also communicate with the private network server 200 through the public network base station 500 and the public network core network device 600 in the public network. The private network base station 300 is an access network device in a private network, and is mainly responsible for sending and receiving wireless signals, managing air interface wireless resources, and managing mobility of an access network side. The private network core network device 400 is a data and switching center in the private network, is responsible for network-side mobility management of the terminal device, S1 link management, and unified switching control and transmission of service data, and has a mobility management function. The private network server 200 is used for service access of the terminal device and exchange control of service data, and provides processing, scheduling and forwarding of voice, video, data and the like.
It should be noted that, in this embodiment, names of the communication devices shown in fig. 1 are not limited. For example, in some scenarios, a base station is also referred to as a network device. Optionally, in different public networks, the public network base station may be an evolved node B (eNB or eNodeB), a relay station or an access point in an LTE communication system, a 5G base station (G node B, gNB) in a future 5G communication system, a wireless transceiver device (next node, NX), or the like. Private network server 200 may also be referred to as a private network service server, dispatch server, etc.

It should be noted that, in this embodiment, the number of each communication device in the communication system is not limited.
In the prior art, as the private network and the public network have different network coverage, the private network signal and the public network signal cannot be measured simultaneously for the single-mode terminal equipment. For example, when a single-mode terminal device is receiving a service in a private network (Btrunc), if a public network signal needs to be measured, the public network signal can be measured only by stopping receiving the service sent by a private network server. Similarly, when the single-mode terminal device is receiving services in the public network, if the private network signals need to be measured, the private network signals can be measured only by stopping receiving the services sent by the private network server. When the terminal equipment stops receiving data to measure signals, the private network server continuously sends the data, so that the single-mode terminal equipment loses the data during measuring the signals, abnormal phenomena such as word loss and interruption of voice services, screen splash of video services and the like occur, and the service quality is reduced.
The invention provides a signal measuring method and a device, aiming at solving the technical problem that data is lost during the signal measuring period of single-mode terminal equipment in the prior art.

Fig. 3 is a message interaction diagram of a signal measurement method according to a second embodiment of the present invention. The signal measurement method provided by the embodiment is applied to a scene that a single-mode terminal device needs to measure a public network signal after accessing a private network. Alternatively, the private network may be a broadband trunked communication network. The network device related to the signal measurement method provided by this embodiment includes a terminal device, a network device of a private network, a core network device of the private network, and a private network server. As shown in fig. 3, the signal measurement method provided in this embodiment may include:
s301, after the terminal device establishes connection with the network device in the private network, whether to trigger signal measurement of the public network is judged.
S302, if the signal measurement of the public network is triggered, the terminal equipment sends a GAP measurement request message to the network equipment.
Correspondingly, the network device receives a GAP measurement request message sent by the terminal device. The GAP measurement request message is used for indicating that the signal measurement of the public network is triggered after the terminal equipment establishes connection with the network equipment in the private network.

And after the terminal equipment triggers signal measurement on the public network, sending a GAP measurement request message to the network equipment. The GAP measurement (GAP measurement), alternatively referred to as measuring GAP, refers to reserving a portion of time (i.e., measuring GAP time). During the period, the terminal equipment does not send and receive any data, and the receiver is tuned to the frequency point of the target cell to carry out signal measurement. And when the GAP time is over, the receiver transfers to the current cell again to resend or receive the data. Correspondingly, the network device does not send data to the terminal device during the GAP time. And continuing to send data to the terminal equipment when the GAP time is over.

Specifically, based on the current signal quality value of the private network and a preset signal quality threshold value, the current signal quality condition of the private network is considered, whether to trigger signal measurement on the public network is judged, and the rationality of triggering signal measurement on the public network is improved.
Optionally, in an implementation manner, determining whether to trigger signal measurement on the public network according to the signal quality value and a preset signal quality threshold may include:
if Ms < MeaSureTH, signal measurements to the public network are triggered.
Wherein, Ms is a Reference Signal Receiving Power (RSRP) value of a serving cell accessed by the terminal device in the private network, and meassource th is a preset Signal quality threshold value.

For example, the GAP measurement request message may be a measurement report obtained after signal measurement is performed on the private network, which is reported by the terminal device. For example, interactive messages under existing GAP measurement mechanisms may be employed. For example, the GAP measurement configuration parameters may include GAP mode and GAP offset (gapOffset). Wherein the GAP pattern is used to indicate the period of the GAP.

Correspondingly, the private network server receives the terminal equipment capability information sent by the terminal equipment.
Specifically, the terminal device capability information may be sent to the private network server after the terminal device establishes a connection with a network device in the private network. The terminal device capability information indicates that the terminal device is not capable of performing signal measurements on both the public network and the private network.
It should be noted that the terminal device accessing the private network may be a single-mode terminal device or a converged terminal. For the converged terminal, the capability information of the terminal equipment can be reported or not.
