Description

Method and terminal equipment for solving cell broadcast

Technical Field

Background

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a communication system using the cell broadcast of the present application. As shown in fig. 1, the communication system 100 includes a network device 102, and the network device 102 may include a plurality of antennas, e.g.,

antennas

104, 106, 108, 110, 112, and 114. Additionally, network device 102 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.

Network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that network device 102 may communicate with any number of terminal devices similar to

terminal devices

116 or 122.

As shown in fig. 1, terminal device 116 is in communication with

antennas

112 and 114, where

antennas

112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, where

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

In a Frequency Division Duplex (FDD) system, forward link 118 can utilize a different Frequency band than reverse link 120, and forward link 124 can employ a different Frequency band than reverse link 126, for example.

As another example, in Time Division Duplex (TDD) systems and Full Duplex (Full Duplex) systems, forward link 118 and reverse link 120 may use a common frequency band and forward link 124 and reverse link 126 may use a common frequency band.

forward links

118 and 124, respectively, the transmitting antennas of network device 102 may utilize beamforming to improve signal-to-noise ratio of

forward links

118 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which a network device transmits through a single antenna to all its terminal devices.

It should be understood that the technical solution of the embodiment of the present application may be applied to an LTE system, as an example and not a limitation. For better understanding of the present application, the embodiments of the present application will be described by taking an LTE system as an example.

Fig. 2 is a schematic flow chart diagram of a method 200 for resolving cell broadcast according to an embodiment of the present application. As shown in fig. 2, the method 200 includes the following.

In 210, the network device to which the first cell belongs transmits a synchronization signal.

Alternatively, the network device transmits the synchronization signal in a broadcast form.

Alternatively, the network device may periodically transmit the synchronization signal.

In 220, the network device to which the first cell belongs transmits a cell broadcast.

In 230, the terminal device resolves the broadcast of the first cell.

Optionally, the terminal device needs to invoke the timing information of the cell when resolving the cell broadcast.

Optionally, the timing information may include a system frame number, a subframe number, and a synchronization position. In the time domain, an LTE system may include a plurality of system frames, and one system frame may include a plurality of subframes.

It should be understood that the synchronization position in the timing information may be one specific time unit included in a subframe, and a plurality of synchronization positions may be included in one subframe.

Optionally, the timing information invoked before the terminal device decodes the cell broadcast may be obtained through a cell search process, may also be obtained through a measurement process, and may also be obtained through some other approaches. Optionally, the first cell may be a local cell of the terminal device, or may be a neighboring cell of the terminal device.

In 240, the terminal device aborts the process of de-broadcasting the first cell with its timing information due to the interruption of the first service.

In 250, the terminal device synchronizes with the network device to which the first cell belongs when determining that the broadcast of the first cell needs to be restored.

Optionally, the terminal device may synchronize with the network device to which the first cell belongs by parsing the synchronization signal.

In 260, the terminal device re-acquires timing information of the first cell through synchronization with the network device.

Therefore, the terminal device may reacquire the timing information of the first cell through synchronization with the network device to which the first cell belongs, and at this time, the timing information of the first cell accurately reflects the current information of the terminal device and the network device to which the first cell belongs.

Optionally, the process of the terminal device in de-broadcasting the first cell by using the timing information of the first cell is interrupted by a first service, and the priority of the first service is higher than that of the de-broadcasting service of the first cell.

Optionally, after the process of performing de-broadcasting on the first cell by using the timing information of the first cell is interrupted by the first service, the terminal device has two situations:

in case one, when the broadcast of the first cell is not important, the broadcast service of the first cell is abandoned;

and in case two, when the broadcast of the first cell is important, the broadcast service of the first cell is recovered.

Optionally, the terminal device may determine that the broadcast of the first cell needs to be resumed when the first service is ended.

Optionally, the process of the terminal device performing the cell search for the first cell may occur in a cell search process when there is no resident cell, where the terminal device may be in a no-service-cell state, and the cell search broadcast in this process may be an initial cell search broadcast in a startup process, or a cell search broadcast in an initial network search process after the terminal device loses network.

Alternatively, for a single-link terminal device, the communication mode of the terminal device may be divided into a master mode and a slave mode, the master mode being a communication mode currently providing a wireless communication service, the slave mode being another communication mode other than the master mode, for example, the master mode is a 4G mode, the slave mode is a 2G mode, and the slave mode starts to operate when a signal of the master mode is very weak or the master mode has no signal.

Alternatively, for a terminal device supporting dual connectivity, for example, for a terminal device with dual cards for dual standby or dual cards for dual-active, the terminal device may include two SIM (subscriber identity module) cards, a communication mode of each of the two SIM cards may be divided into a master mode and a slave mode, the master mode and the slave mode of each of the two SIM cards may be the same or different, the master mode of each of the two SIM cards may provide different communication services or the same communication services, and similarly, one of the two SIM cards may provide master mode communication services and the other SIM card provides slave mode communication services. It should be understood that the multi-card multi-standby or multi-card multi-pass can be regarded as a special dual-card dual-standby or dual-card dual-pass.

Optionally, the process of the terminal device broadcasting the first cell may also occur before cell reselection occurs in an idle state of the master mode. The idle state of the master mode may be that the master mode is in a non-connected state, no data transmission service is performed, and the cell reselection may be to select a cell with a best signal compared with the strength of signals of surrounding cells. In order to acquire signal information of surrounding cells, the terminal device performs a cell broadcast resolving operation before cell reselection occurs in a master mode idle state.

Optionally, the process of the terminal device performing the de-broadcasting on the first cell may also occur in a background search flow performed in an idle state of the master mode. The idle state of the master model may be that the master model is in a non-connected state and does not perform a data transmission service. The terminal device executes a background search process when the master mode is in an idle state, wherein the background search process is to actively search which network mode signals around are better, and an operation of cell broadcast decoding exists in the process.

Optionally, the process of the terminal device performing the de-broadcasting on the first cell may also occur in an ANR (automatic neighbor relation) flow during the connection state down-trenching of the master mode. In the master mode connection state, a protocol stack in the terminal device may send an automatic neighbor relation flow to the physical layer entity, the terminal device may execute the automatic neighbor relation flow during a master subchannel in the master mode connection state, an operation of resolving a cell broadcast exists in the automatic neighbor relation flow, and the terminal device may further obtain information of surrounding cells. The connection state down-channel division period of the main mode means that the main mode automatically interrupts connection state services at intervals, the terminal device can perform operations such as measurement, broadcast resolution and the like during the channel division period, the time duration of the connection state down-channel division period of the main mode is fixed and can be preset, and in the automatic neighbor cell relation flow, the terminal device performs cell broadcast resolution operation in order to acquire surrounding cell information.

Optionally, the process of the terminal device performing the broadcast decoding on the first cell may also occur in an ANR flow during discontinuous reception in the master mode connection state, where in the master mode connection state, a protocol stack in the terminal device may send an automatic neighbor relation flow to the physical layer entity, the terminal device may execute the automatic neighbor relation flow in a non-data reception period in the master mode connection state, and an operation of the broadcast decoding on the cell exists in the automatic neighbor relation flow, so that the terminal device may obtain information of surrounding cells.

Optionally, the process of the terminal device de-broadcasting the first cell may also occur in a background search process performed by the slave mode during the master mode control break, where the slave mode performs the background search process during the master mode control break, that is, the master mode is left for a period of time to be used by the slave mode, the master mode exits the master mode service during the period of time, and the slave mode performs the background search process during the period of time. Specifically, the background search process performed from the template means: the terminal device controls which network mode signals around the slave mode active search are better. The master mode controls the time length of the sub-channel, the specific time length is required to meet the requirement of executing the background search process from the slave mode, and the operation of cell broadcast solving exists in the process, wherein the cell broadcast solving is used for acquiring network signals of surrounding cells.

For a terminal device supporting a dual-card service, optionally, when a first SIM card of at least two SIM cards of the terminal device is released from the broadcast of the first cell, the first SIM card may be interrupted by any one of the following services of another at least one SIM card of the at least two SIM cards: a voice service; a tracking area update service; measuring the service; short message service; multimedia message service; a data service; the paging service is released; initial network searching service; random access service; and switching the service.

Optionally, the priority of the first service of the other at least one of the at least two SIM cards is higher than the cell resolution broadcast of the first SIM card of the at least two SIM cards.

For one card of the terminal device including multiple cards, for example, taking a second SIM card of the at least one SIM card as an example, optionally, when a second SIM card of the at least one SIM card of the terminal device decodes broadcasting of the first cell before cell reselection occurs in an idle state of the master mode, the master mode serving the second SIM card may be interrupted by a paging decoding service of the second SIM card.

Optionally, when a second SIM card in the at least one SIM card of the terminal device solves the broadcast of the first cell in the background search process performed in the idle state of the master mode, the second SIM card may be interrupted by a paging solving service of the second SIM card, a measurement service of the second SIM card, or a service area system message solving service of the second SIM card.

Optionally, when a second SIM card of the at least one SIM card of the terminal device releases the broadcast of the first cell in the ANR procedure during the connection state of the master mode in the groove, the paging release service of the second SIM card may be interrupted.

Optionally, when a second SIM card in the at least one SIM card of the terminal device releases the broadcast of the first cell in the ANR flow during discontinuous reception in the connection state of the master mode, the second SIM card may be interrupted by a paging release service of the second SIM card, or may be interrupted by a connection state service of the second SIM card.

Optionally, when a second SIM card of the at least one SIM card of the terminal device decodes the broadcast of the first cell in a background search procedure performed during the slave mode in the idle state of the master mode during control of the ditching, the second SIM card may be interrupted by a paging decoding service of the second SIM card, a measurement service of the second SIM card, or a service decoding area system message service of the second SIM card, where the slave mode serves the second SIM card.

In 270, the terminal device continues to decode the broadcast of the first cell based on the timing information retrieved.

Optionally, the interruption by the first service when the terminal device decodes the broadcast of the first cell may occur in a stage of decoding the master information block MIB information, or may occur in a stage of decoding a system information block SIB information.

Optionally, in this embodiment of the present application, if the process of the terminal device performing broadcast decoding on the first cell by using the timing information of the first cell is interrupted and occurs at a stage of decoding the MIB information of the master information block, the terminal device continues to decode the MIB information according to the timing information obtained again, and after the MIB information is decoded, updates the system frame number of the first cell to the first system frame number, and decodes SIB information of the system information block according to the first system frame number; or

If the process of the terminal equipment for broadcasting solution of the first cell by using the timing information of the first cell is interrupted and occurs in the stage of SIB information solution, the MIB information is dissolved according to the timing information acquired again, after the MIB information is dissolved, the system frame number of the first cell is updated to be a second system frame number, and the SIB information is dissolved according to the second system frame number.

Optionally, a physical broadcast channel is first established for receiving the MIB information before the MIB information is decoded, and the physical broadcast channel is released after the MIB information is decoded.

Optionally, after the MIB is successfully decoded, a physical downlink shared channel is first established for receiving the SIB information, and after the SIB information is successfully decoded, the physical downlink shared channel is released.

Optionally, during the period of solving that the broadcast of the first cell is interrupted, no real-time timing tracking is performed, in this process, the timing information may have changed, when the interruption time of solving that the broadcast of the first cell is interrupted is slightly long, for example, more than 10ms, the timing information deviation may be relatively large, and when the terminal device determines to continue to solve the broadcast of the first cell, the operation of reacquiring the timing information is added, so that the influence of the timing deviation on the solution of the broadcast is overcome. Therefore, the method and the device can improve the accuracy of solving the first cell broadcast and shorten the time for solving the first cell broadcast.

Furthermore, the embodiment can improve the user experience of the terminal device in starting up and searching the network, reduce the power consumption in the idle state and improve the service throughput in the connection state.

Further, when the terminal device uses a low-cost single crystal oscillator, a large frequency offset may be caused, and especially when the timing information of the terminal device has a deviation, the frequency offset caused after the time domain and frequency domain conversion is larger, and may have a large influence on the decoding of the cell physical broadcast channel and the decoding of the system information block, so that the embodiment may overcome the influence of the frequency offset on the decoding of the cell broadcast.

Fig. 3 is a schematic flow chart diagram of a method 300 of resolving cell broadcast in accordance with another embodiment of the present application. As shown in fig. 3, the method 300 includes the following steps, wherein the steps 310 to 330 can refer to the steps 210 to 230 in the previous embodiment of fig. 2.

In 340, when the terminal device cannot call the timing information of the cell in the process of determining the broadcast of the cell, the terminal device synchronizes with the network device to which the cell belongs.

Optionally, in the process of resolving the cell broadcast, the terminal device first determines whether the timing information of the cell can be normally invoked, if the timing information of the cell can be normally invoked, the cell broadcast is normally resolved according to the timing information of the cell, and if the timing information of the cell cannot be normally invoked, the terminal device needs to synchronize with the network device to which the cell belongs to obtain the timing information of the cell, so as to resolve the cell broadcast.

Timing information for the cell is obtained through synchronization with the network device at 350.

It should be understood that the terminal device needs to invoke the timing information of the cell when decoding the cell broadcast, and cannot decode the cell broadcast when the timing information of the cell is absent, so that the timing information of the cell can be acquired by synchronizing with the network device to which the cell belongs.

It should be understood that the terminal device cannot invoke the timing information of the cell in the process of determining the broadcast of the solution cell, in which case the solution cell broadcast may be referred to as a blind solution cell broadcast.

Alternatively, the cell here may be a neighbor cell of the terminal device.

Optionally, in this embodiment of the present application, the process of performing de-broadcasting on the cell occurs: and in an ANR flow in a connected state and/or in an idle state.

Optionally, the terminal device may synchronize with the network device to which the cell belongs by parsing the synchronization signal.
