There may be systems of other industries working around the frequency point where they work, causing random interference to the LTE230 system. Once the synchronization channel and the system information are interfered, for a terminal having accessed to the system, when cell synchronization cannot be successfully maintained (successful detection of the synchronization channel), other synchronization signals and a system information transmission resource configuration set which cannot be switched to the cell are continuously detected and received, for an IDLE state (IDLE) terminal, a cell reselection process of the terminal is triggered, and for a Connected state (Connected) terminal, an RRC connection reestablishment process is triggered.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
At present, the power distribution and utilization network mostly adopts GPRS and CDMA services provided by leased telecommunication operators as wireless communication means of services such as information acquisition and the like. Although the public network does not need network deployment and later maintenance, and only needs to pay lease fees to operators, the network with public voice communication and data service as the highest priority cannot meet the requirements of power service information safety, instantaneity and service quality all the time. Therefore, the construction of the wireless private network becomes an inevitable trend of the development of the smart grid power communication.
The LTE230 system is a wireless private network communication system operating in a 230MHz frequency band, and the characteristic of long coverage distance of a low frequency band makes the LTE230 system superior to other systems in both network establishment and later maintenance costs. In addition, in terms of frequency usage policy, the national radio regulatory commission has granted 40 dedicated frequency points to the power industry for the 230MHz frequency band. Therefore, the LTE230 system has good popularization and application values in the field of power distribution and utilization by combining the 4G LTE advanced technology and the wide-coverage advantage based on the natural advantages of the frequency use policy in the power industry.
The existing LTE230 system scheme continues to use the LTE technical scheme in terms of design of air interface synchronization signals and system information, and a fixed carrier is selected for a cell system to transmit synchronization signals and system broadcast information MIB. There may be systems of other industries working around the frequency point where they work, causing random interference to the LTE230 system. Once the synchronization channel and the system information are interfered, for a terminal having accessed to the system, when cell synchronization cannot be successfully maintained (successful detection of the synchronization channel), other synchronization signals and a system information transmission resource configuration set which cannot be switched to the cell are continuously detected and received, for an IDLE state (IDLE) terminal, a cell reselection process of the terminal is triggered, and for a Connected state (Connected) terminal, an RRC connection reestablishment process is triggered.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the allocation situation of 230MHz spectrum in our country. The existing LTE230 system scheme continues to use the LTE technical scheme in terms of design of air interface synchronization signals and system information, and a fixed carrier is selected for a cell system to transmit synchronization signals and system broadcast information MIB. There may be systems of other industries working around the frequency point where they work, causing random interference to the LTE230 system. The different colors in the figure represent authorized carriers assigned to different industries, and the white represents available carriers not explicitly assigned to occupation by a particular industry, each carrier being 25kHz wide. Future LTE230 systems may use either dedicated carriers not allocated to the power industry (red part of the figure) or idle carriers not specifically allocated for use by each particular industry (white part of the figure).
Fig. 2 is a flowchart of an embodiment of a method for allocating transmission resources of synchronization signals and system information of a terminal. The method for configuring the terminal synchronization signal and the transmission resource provided by the embodiment of the application comprises the following steps:
step 11: a set of synchronization signal and system information transmission resource configurations is obtained.
For a terminal which has accessed to the network, the network notifies the terminal of the synchronization signal and the system information transmission resource configuration set, and the way for the terminal to obtain the synchronization signal and the system information transmission resource configuration set may be a periodic system broadcast information way, a system information request way or a dedicated RRC signaling way. Synchronization signals are sent on a synchronization signal carrier, LTE system synchronization signals include primary synchronization signals PSS and secondary synchronization signals SSS, and system information MIB is transmitted on system information transmission resources, i.e., broadcast carriers.
For example, as shown in fig. 3, fig. 3 is a schematic diagram of carrier channel division of an embodiment of a terminal synchronization signal and transmission resource configuration method. The network sends a synchronization signal and a system information transmission resource configuration set to the accessed terminal. The frequency width of each carrier channel is, for example, 25kHz, and the synchronization signal and the system information MIB are transmitted on a synchronization signal carrier and a broadcast carrier, respectively. The synchronization signals include a primary synchronization signal PSS and a secondary synchronization signal SSS, and if the position of the corresponding broadcast carrier on the frequency domain can be calculated according to the synchronization signal carrier or a cell physical layer identifier PCI carried in the synchronization signals, the information transmission resource configuration set may not be indicated in an explicit manner.
Step 12: entering an RRC idle state or an RRC connected state.
A terminal that has accessed to the network obtains a synchronization signal and a system information transmission resource configuration set, and the terminal generally has two states according to the data transmission situation. After a period of time without data transmission, the terminal enters an RRC idle state; when data is transmitted, the terminal enters an RRC connection state.
For example, a terminal which has accessed to a network obtains a synchronization signal and a system information transmission resource configuration set, and when data is transmitted, the terminal enters an RRC connection state; if there is no data transmission, the terminal enters the RRC idle state after a period of time.
Step 13: when the currently monitored synchronous channel or system information transmission resource is interfered, switching to other synchronous channels or system information transmission resources of the current cell for monitoring.
When the transmission resource of the synchronization channel or the system information MIB monitored by the terminal is suddenly severely interfered by other external systems, so that the current synchronization channel cannot be monitored normally, or the transmission of the system information MIB cannot be received correctly, if the other synchronization channels or the transmission resource of the system information MIB in the current serving cell are not interfered, the terminal switches to the other synchronization channels or the transmission resource of the system information MIB in the current serving cell to monitor.
For example, as shown in fig. 3, fig. 3 is a schematic diagram of carrier channel division of an embodiment of a terminal synchronization signal and transmission resource configuration method. For example, the terminal currently listens to use the first synchronization signal and the configuration set of system information transmission resources, that is, the synchronization channel is carrier 2, and the transmission resource of the system information MIB is carrier 4. When carrier 2 or carrier 4 is interfered and normal monitoring cannot be performed, if the second synchronization signal and the system information transmission resource configuration set are not interfered, the terminal may switch to the second synchronization signal and the system information transmission resource configuration set of the current serving cell to perform monitoring, that is, the synchronization channel is carrier n +1, and the transmission resource of the system information MIB is carrier n + 3.
Fig. 4 is a flowchart of a method for configuring transmission resources of synchronization signals and system information of a terminal according to a preferred embodiment. The application provides a method for configuring transmission resources of terminal synchronization signals and system information, which comprises the following steps:
step 21: a set of synchronization signal and system information transmission resource configurations is obtained. (same step 11)
Step 22: entering an RRC idle state or an RRC connected state. (same step 12)
Step 23: when the currently monitored synchronous channel or system information transmission resource is interfered, switching to other synchronous channels or system information transmission resources of the current cell for monitoring. (same step 13)
Step 24: when the cell is in an RRC idle state, if other synchronous channels or system information transmission resources of the current cell are all interfered, triggering the reselection process of the serving cell; when the cell is in the RRC connection state, if other synchronous channels or system information transmission resources of the current cell are all interfered, the RRC connection reestablishment process is triggered.
In step 23, when the synchronization channel or the system information transmission resource currently monitored by the terminal is interfered, the terminal first attempts to switch to another synchronization channel or another system information transmission resource of the current cell for monitoring, and if all the other synchronization channels or the system information transmission resources of the current cell are interfered, the terminal cannot switch. In this case, if the terminal is in the RRC idle state, the terminal may trigger a reselection procedure of the serving cell; if the terminal is in the RRC connected state, the terminal triggers an RRC connection reestablishment procedure.
For example, as shown in fig. 3, fig. 3 is a schematic diagram of carrier channel division of an embodiment of a terminal synchronization signal and transmission resource configuration method. For example, the terminal currently listens to use the first synchronization signal and the configuration set of system information transmission resources, that is, the synchronization channel is carrier 2, and the transmission resource of the system information MIB is carrier 4. When carrier 2 or carrier 4 is interfered and normal monitoring cannot be performed, if the second synchronization signal and the system information transmission resource configuration set are not interfered, the terminal may switch to the second synchronization signal and the system information transmission resource configuration set of the current serving cell to perform monitoring, that is, the synchronization channel is carrier n +1, and the transmission resource of the system information MIB is carrier n + 3. For example, when the second synchronization signal and the system information transmission resource configuration set are also interfered, in this case, if the terminal is in the RRC idle state, the terminal may trigger a reselection procedure of the serving cell; if the terminal is in the RRC connected state, the terminal triggers an RRC connection reestablishment procedure.
Preferably, the obtaining mode of obtaining the cell synchronization signal and the system information transmission resource configuration set is a periodic system broadcast information mode, a system information request mode or a dedicated RRC signaling mode.
In step 11, the terminal needs to obtain a synchronization signal and a system information transmission resource configuration set. For a terminal having access to a network, the manner of obtaining the synchronization signal and the system information transmission resource configuration set may be a periodic system broadcast information manner, a system information request manner, or a dedicated RRC signaling manner. Synchronization signals are sent on a synchronization signal carrier, LTE system synchronization signals include primary synchronization signals PSS and secondary synchronization signals SSS, and system information MIB is transmitted on system information transmission resources, i.e., broadcast carriers.
Fig. 5 is a flowchart of an embodiment of acquiring a synchronization signal and a system information transmission resource configuration set by a periodic system broadcast information. The method for acquiring the synchronization signal and the system information transmission resource configuration set comprises the following steps:
step 31: and receiving the periodic system broadcast information to obtain a synchronization signal and a system information transmission resource configuration set.
And the terminal receives the periodic system broadcast information of the current service cell in the process of finishing the residence of the current service cell. The system broadcast information is divided into periodic system information MIB and periodic system information SIB. The network sends periodic system broadcast information to the terminal, and there may be two ways: the first scheme is as follows: the synchronous signal and the system information transmission resource set are transmitted through a periodic system information MIB; scheme II: the set of synchronization signals and system information transmission resources are transmitted via a periodic system information SIB, wherein the transmission resources and the periodic information used for the transmission of the periodic system information SIB are indicated by a periodic system information MIB. If the scheme one is used, the terminal receives the system information MIB through the transmission period of the periodic system information MIB which is defaulted by the system, and acquires the synchronization signal of the current cell and the configuration of the transmission resource set of the system information; if the scheme two is used, the terminal receives the system information MIB through the transmission period of the periodic system information MIB which is defaulted by the system, and after the transmission resource and the periodic information which are used by the transmission of the periodic system information SIB are obtained, the periodic system information SIB is received, and the synchronization signal and the system information transmission resource set configuration of the current cell are obtained.
Step 32: entering an RRC idle state or an RRC connected state. (same step 12)
Step 33: when the currently monitored synchronous channel or system information transmission resource is interfered, switching to other synchronous channels or system information transmission resources of the current cell for monitoring. (same step 13)
Preferably, the periodic system broadcast information is MIB or SIB.
In the method for acquiring the synchronization signal and system information transmission resource configuration set in a periodic system broadcast information mode, the system broadcast information is divided into a periodic system information MIB and a periodic system information SIB, and the synchronization signal and system information transmission resource set can be transmitted through the periodic system information MIB or the periodic system information SIB.
Fig. 6 is a flowchart of an embodiment of obtaining a synchronization signal and a system information transmission resource configuration set by a system information request. The method for acquiring the synchronization signal and the system information transmission resource configuration set comprises the following steps:
step 41: and sending the system information request identification to the network.
The method of obtaining the synchronization signal and the system information transmission resource configuration set by the system information request method is also called the system information obtaining method of On-demand, different types of system information are classified and identified by SIB index, for example, the cell synchronization signal and the system information transmission resource configuration can be classified into SIB 2. In this step, the terminal sends a system information request message to the network, where the system information request message carries a system information request identifier SIB index.
Step 42: and receiving system information, and acquiring a synchronization signal and a system information transmission resource configuration set.
The network receives and analyzes a system information request identifier SIB index sent by the terminal, and sends system information indicated by the system information request identifier SIB index to the terminal through a system information message, wherein the system information comprises a synchronization signal and a system information transmission resource configuration set. The terminal receives and analyzes the system information sent by the network, and can obtain the synchronization signal and the system information transmission resource configuration set contained in the system information.
Step 43: entering an RRC idle state or an RRC connected state. (same step 12)
Step 44: when the currently monitored synchronous channel or system information transmission resource is interfered, switching to other synchronous channels or system information transmission resources of the current cell for monitoring. (same step 13)
Fig. 7 is a flowchart of an embodiment of obtaining a synchronization signal and a system information transmission resource configuration set by dedicated RRC signaling. The method for acquiring the synchronization signal and the system information transmission resource configuration set comprises the following steps:
step 51: and sending RRC connection request signaling to the network.

Step 52: and receiving the RRC connection establishment message, wherein the RRC connection establishment message comprises a synchronization signal and system information transmission resource configuration set information, and acquiring the synchronization signal and system information transmission resource configuration set.
After receiving the RRC request signaling, the network sends an RRC connection setup message, which is generally an RRCConnectionSetup message or an RRCConnectionReconfiguration message, to the terminal, and notifies the terminal of the synchronization signal and the system information transmission resource set. The terminal receives the RRC connection establishment message sent by the network, analyzes the RRC connection establishment message to obtain a synchronization signal and a system information transmission resource configuration set, and sends an RRC connection confirmation message called RRCConnectionSetupComplex message or RRCConnectionReconfiguration complete message to the network.
Step 53: entering an RRC idle state or an RRC connected state. (same step 12)
Step 54: when the currently monitored synchronous channel or system information transmission resource is interfered, switching to other synchronous channels or system information transmission resources of the current cell for monitoring. (same step 13)
