In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic data interaction diagram of a cell wake-up method in an embodiment of the present application. The terminal in fig. 1 refers to a terminal with a wake-up intention, the network device refers to an access network device corresponding to a cell where the terminal currently resides, and the network device is in a power saving mode.
In the solution of the embodiment of the present application, in the power saving mode may mean that the random access function of the cell is in a turned-off state and/or at least part of the system information is not transmitted. That is, the terminal cannot perform random access and/or the terminal cannot acquire system information of the cell.
In the solution of the embodiment of the present application, the cell in the power saving mode at least periodically transmits a synchronization signal (Synchronous Signal, abbreviated SS) so that the terminal can learn the coverage of the cell and acquire coarse synchronization.
The cell wakeup method shown in fig. 1 may include steps S11 to S13.
Step S11, the terminal determines a wake-up signal corresponding to the wake-up intention and/or a transmission resource for transmitting the wake-up signal according to the wake-up intention of the terminal and the first configuration information.
Step S12, the terminal sends a wake-up signal; accordingly, the network device receives the wake-up signal.
In step S13, the network device determines the wake-up intention of the terminal according to the first configuration information and the wake-up signal and/or the transmission resource for transmitting the wake-up signal.
In step S14, the network device responds to the wake-up intention.
In the implementation of step S11, the terminal may first determine its own wake-up intention. The wake-up intention may refer to actions that the terminal expects the network device to perform, or data, signaling, services, etc. that the terminal expects the network device to provide.
Specifically, the wake-up intent may include: the requesting cell transmits at least one system information and/or the requesting cell opens a random access service. More specifically, the system information transmitted by the requesting cell is different, and the wake-up intention of the terminal is also different, that is, the wake-up intention of the terminal may be different according to the requested system information.
In a specific example, the wake-up intention of the terminal may be at least selected from the following:
intent 1: the requesting cell transmits at least one system information, which may include at least one of: a master information block (Master Information Block, MIB for short), a system information block (System Information Block, SIB for short). The MIB contains important information such as cell bandwidth, system frame number, etc., and the SIBs are various (for example, SIB1, SIB2, SIB3, SIB4 and SIB 5), and each SIB contains a series of system information parameters related to a certain function, such as some SIBs related to cell reselection and some SIBs related to positioning, but not limited thereto.
More specifically, the intention 1 may be to request only the cell to transmit system information and not to provide a random access function, i.e., the terminal does not request the cell to turn on a random access service, and the intention 1 may request the cell in the power saving mode to broadcast part or all of a system message carrying system information required for a function or service that the terminal desires to develop.
In a specific example, in a scenario where the terminal needs to acquire a cell reselection parameter, the terminal requests the cell to send one or more of SIB2, SIB3, SIB4 and SIB 5; and under the condition that the terminal needs to develop positioning service, the terminal requests the service cell to send system information related to positioning.
Intent 2: the requesting cell transmits at least SIB1 and turns on a random access service (i.e., a service providing random access). More specifically, the cell may be requested to provide SIB1 and to turn on a random access service.
In a specific example, the terminal desires to access the network to perform the service, in which case the cell is required to broadcast necessary system information, such as SIB1, so that the terminal knows the random access resource to access the network to perform the service.
Intent 3: the requesting cell opens a random access service. More specifically, the intention 3 may be a service that requests that the cell provide only random access without providing system information.
Specifically, in a practical application scenario, the serving cell does not modify the system information (especially modifying the parameters related to the access cell) frequently, and the system information retained by the terminal may be valid for a period of time (the system message within 3 hours may be generally considered valid). In this case, the terminal may directly initiate a random access procedure by using the random access parameter in the stored system information, so as to access the network to develop a service. Therefore, in this access procedure, the serving cell does not need to send system information, and the terminal only needs to turn on the random access service.
In a specific example, the terminal periodically performs tracking area update (Tracking Area Update, TAU for short), and the terminal can interact with the network device based on the original system information, such as SIB1 configuration, so as to complete TAU.
Further, the terminal may determine a wake-up signal and/or a transmission resource for transmitting the wake-up signal according to the determined wake-up intention and the first configuration information. The first configuration information is used for indicating a mapping relation between the wake-up intention and the wake-up signal and/or transmission resources used for transmitting the wake-up signal.
In a specific implementation, the first configuration information may be preconfigured by the network, i.e. the mapping between the wake-up intention and the wake-up signal and/or transmission resources may be preconfigured by the network. In other words, the network pre-configures the indication of each wake-up intention.
Specifically, the different wake intents may be indicated in any one or more of the following ways:
mode one: different time domain resources are employed to indicate different wake-up intents. In other words, the time domain resources used to transmit the wake-up signal vary with wake-up intent. Wherein the time domain resource may be a time slot.
In a specific example, a unique corresponding time domain resource may be preconfigured for each wake-up intention, but is not limited thereto.
For example, time slot 1, time slot 2, and time slot 3 are preconfigured, time slot 1 being used to indicate intention 1 to the serving cell (e.g., request the serving cell to send SIB2 to SIB5, but without the need to turn on the service of the random access function); slot 2 is used to indicate intent 2 to the serving cell (e.g., serving cell needs to send at least SIB1 while turning on the random access function's service); slot 3 is used to indicate intent 3 to the serving cell (e.g., request the serving cell to turn on the random access function service, but system information may not be necessarily transmitted).
Specifically, the first indication information may include a mapping relationship between the wake-up intention and the time domain resource, and the terminal may determine the time domain resource for transmitting the wake-up signal according to the wake-up intention of the terminal and the first indication information. In step 12, the terminal may transmit a wake-up signal on a time domain resource determined according to the wake-up intention.
Accordingly, in step S13, after receiving the wake-up signal, the network device may determine the wake-up intention of the terminal according to the first configuration information and the time domain resource for transmitting the wake-up signal.
Mode two: different frequency domain resources are employed to indicate different wake-up intents. In other words, the frequency domain resources used to transmit the wake-up signal vary with the wake-up intent. Wherein, the frequency domain resource may be a frequency location where a wake-up signal is transmitted.
Specifically, the first indication information may include a mapping relationship between the wake-up intention and the frequency domain resource, and the terminal may determine the frequency domain resource for transmitting the wake-up signal according to the wake-up intention of the terminal and the first indication information. Further, in step S12, the terminal may transmit a wake-up signal on the frequency domain resource determined according to the wake-up intention.
Accordingly, in step S13, after receiving the wake-up signal, the network device may determine the wake-up intention of the terminal according to the first configuration information and the frequency domain resource for transmitting the wake-up signal.
Mode three: different wake-up signals are used to indicate different wake-up intents. In other words, the wake-up signal varies with the wake-up intention. More specifically, the wake-up signals corresponding to different wake-up intents may be different uplink signals located on the same transmission resource. Wherein, the difference of the wake-up signals can include: the types of wake-up signals are different and/or the content of the wake-up signals is different.
Specifically, the first configuration information may include a mapping relationship between the wake-up intention and the wake-up signal, and the terminal may determine the wake-up signal according to the wake-up intention and the first indication information.
Accordingly, in step S13, after receiving the wake-up signal, the network device may determine the wake-up intention of the terminal according to the first configuration information and the wake-up signal.
In a specific example, the wake-up signal may be a random access Preamble (Preamble), the first indication information may include a mapping relationship between a wake-up intention and the random access Preamble, and the terminal may determine the corresponding random access Preamble according to its wake-up intention. For example, the serving cell allocates uniform random access opportunities, allocates different random access preambles to different wake-up intents, such as Preamble1 to intent 1, preamble 2 to intent 2, preamble 3 to intent 3, etc.
In practical applications, other uplink signals may be used as the wake-up signal, which is not limited in this embodiment.
It should be noted that the wake-up intention may be indicated by a single indication, that is, any one of the wake-up signal, the time domain resource transmitting the wake-up signal, and the frequency domain resource transmitting the wake-up signal is preconfigured. The wake-up intention may also be indicated in a joint indication, i.e. a combination of any of the wake-up signal, the time domain resources transmitting the wake-up signal and the frequency domain resources transmitting the wake-up signal is preconfigured. The embodiments of the present application are not limited in this regard.
In the implementation of step S14, after determining the wake-up intention of the terminal, the serving cell may respond to the wake-up intention in a manner corresponding to the wake-up intention.
Taking the above intent 1 as an example, the serving cell may send the requested system information to the terminal; taking the above intent 2 as an example, the serving cell may send at least SIB1 to the terminal and turn on the random access service; taking the above intent 3 as an example, the serving cell may turn on the random access service.
In a specific example, the serving cell may respond to wake-up signals transmitted by the plurality of terminals (i.e., respond to wake-up intents of the plurality of terminals) to satisfy the wake-up intents of the plurality of terminals as much as possible. The wake-up intents of the plurality of terminals may be the same or different.
For example, if a plurality of terminals each request a cell reselection parameter, the serving cell may transmit (e.g., broadcast) system information related to cell reselection; if a plurality of terminals all request SIB1 and start random access service, a service cell can send SIB1 and start random access service; if one terminal requests SIB1 and starts random access service and the other terminal only requests starting random access service, the serving cell may transmit SIB1 and start random access service. Further, if the terminal does not receive the response of the serving cell within a preset period of time, the wake-up signal may be transmitted again. The starting time of the preset time period may be an ending time of sending the wake-up signal, and the duration of the preset time period may be preconfigured by the network.
When the number of times of sending the wake-up signal reaches a preset threshold value, the response of the serving cell is not received yet, and the wake-up failure can be determined. Further, the terminal may reselect other cells to camp on. For example, the number of times the terminal transmits the wake-up signal requesting the serving cell to transmit SIB1 reaches the preset threshold, but SIB1 transmitted by the serving cell is still not received, at which time the cell where the terminal resides may be reselected.
Further, the cell in which the terminal reselects may be a cell in a non-power saving mode or a cell in a power saving mode.
In one non-limiting example, when the wake-up failure reselects the camped cell, the terminal selects the cell in the non-power saving mode to camp on even though the network configures the terminal to preferentially select the cell in the power saving mode, so as to avoid the situation that multiple wake-up failures occur.
In view of the above, in the solution of the embodiment of the present application, in order to cope with the requirements of residence of the terminal in the coverage area and the possible need of developing the service, a wake-up mechanism triggered by the terminal is introduced, so that the inactive serving cell (i.e. the serving cell in the power saving mode) can timely provide the access service request of the terminal, and transmit signaling and data for the terminal.
Further, there may be multiple candidate cells in the area where the terminal is located, where the candidate cells may refer to cells that may be selected by the terminal for camping. Wherein the plurality of candidate cells may include: the terminal comprises a service cell and a neighbor cell, wherein the service cell can be a cell where the terminal is currently resident, and the neighbor cell can be a neighbor cell of the service cell. In the solution of the embodiment of the present application, the first configuration information corresponding to the plurality of candidate cells may be the same or different.
The following describes a case where a plurality of candidate cells correspond to different first configuration information.
In a specific implementation, the network may configure, for each candidate cell, respective first configuration information. The terminal may obtain third configuration information, where the third configuration information may include first configuration information corresponding to each candidate cell.
After the terminal resides in any one of the candidate cells, the first configuration information corresponding to the resident cell may be applied. More specifically, the camped cell transmits a synchronization signal indicating the cell identity. Accordingly, the terminal can learn the cell identity of the cell in which it resides.
Further, the terminal may determine the first configuration information corresponding to the resident cell according to the cell identifier of the resident cell and the third configuration information. When the terminal has a wake-up requirement, the steps shown in fig. 1 may be performed to wake up the camped cell.
By adopting the scheme, as the third configuration information comprises the first configuration information of each candidate cell in the area where the terminal is located, the terminal resides in any candidate cell, and the first configuration information of the resident cell can be obtained according to the cell identification and the third configuration information, so that the resident cell is awakened, and the problem of mobility of the terminal can be solved.
Referring to fig. 2, fig. 2 is a flow chart of another cell wake-up method in an embodiment of the present application. The method shown in fig. 2 may be performed by a terminal.
In the prior art, a cell is allowed to be in a power saving mode based on the consideration of power saving, for example, a system message is turned off, and/or a random access service is turned off. In the case where one or more cells in the power saving mode exist in the area, load imbalance among the cells is liable to occur.
Specifically, if system information of a cell is received, the terminal determines that the cell is campable, and if system information of a cell is not received, the terminal determines that the cell is non-campable. Thus, if a cell is in a power saving mode, terminals always do not tend to camp on the cell, i.e., terminals always tend to camp on a cell in a normal state (i.e., non-power saving mode), which may cause an excessive number of terminals camping on a single normal state cell, while cells in a power saving mode do not have a situation where terminals camp on, and the load between cells is unbalanced.
Therefore, the embodiment of the application proposes that the network pre-configures the terminal to preferentially select the cell in the power saving mode for residence, so that the terminal is guided to reside in a proper cell, and both power saving and load balancing are considered.
The cell wakeup method shown in fig. 2 may include the steps of:
step S21: determining a plurality of candidate cells;
step S22: and selecting a target cell to be camped on from the plurality of candidate cells according to second configuration information, wherein the second configuration information is used for indicating whether the candidate cell in the power saving mode is preferentially selected as the target cell.
In the implementation of step S21, the terminal may determine a plurality of candidate cells, where the candidate cells may refer to cells available for the terminal to select for camping.
Specifically, the plurality of candidate cells may include: the terminal comprises a service cell and a neighbor cell, wherein the service cell can be a cell where the terminal is currently resident, and the neighbor cell can be a neighbor cell of the service cell.
In a specific implementation, the terminal may measure signals of the serving cell and the neighboring cells to determine a plurality of candidate cells, and the specific manner of determining the plurality of candidate cells is not limited in this embodiment.
In a specific implementation of step S22, the terminal may determine, according to the second configuration information, a target cell to camp on from the plurality of candidate cells. Further, after determining the target cell, the terminal resides in the target cell.
In a specific implementation, the second configuration information is preconfigured by the network. That is, the network may pre-configure whether the terminal preferentially selects a cell in the power saving mode as the target cell. If the terminal accesses the network last time, the network configures second configuration information; or the terminal indicates the second configuration information by the system message of the cell in which the system message was broadcast last time the terminal was camping.
In case that the network pre-configures the terminal to preferentially select the cell in the power saving mode, the terminal has an opportunity to select the candidate cell in the power saving mode as the target cell.
It should be noted that, regarding the candidate cell in the power saving mode as the target cell, it is also necessary to satisfy the signal quality requirement. If the signal quality of the candidate cell in the power saving mode is poor, it is not suitable for camping, and therefore, the terminal can determine whether the signal quality of the candidate cell in the power saving mode meets a preset camping condition, so as to avoid camping on the cell with poor signal quality.
For example, after selecting a candidate cell in the power saving mode as a target cell, the terminal may determine whether the signal quality of the cell satisfies a preset camping condition before camping, if so, camping is performed, otherwise, the target cell to be camped is reselected.
Because the cell in the power saving mode in the embodiment of the present application may send the synchronization signal, the terminal may measure the synchronization signal to determine whether the signal quality of the cell meets a preset residence condition. For example, whether the received power of the synchronization signal is greater than a preset threshold is determined, if yes, it is determined that the signal quality of the cell transmitting the synchronization signal meets a preset residence condition, and residence may be performed, otherwise, it is determined that the signal quality of the cell does not meet the preset residence condition.
Case one: the second configuration information may include: when the frequency priorities of the candidate cell in the power saving mode and the candidate cell in the non-power saving mode are the same, the candidate cell in the power saving mode is preferentially selected as the target cell. That is, the network configures in advance the candidate cell in the power saving mode preferably in the case where the frequency priorities are the same.
Taking the first candidate cell and the second candidate cell as examples, if the frequency priorities of the first candidate cell and the second candidate cell are the same, and the first candidate cell is in the power saving mode, the second candidate cell is in a normal state (i.e., the second candidate cell is in the non-power saving mode), and the first candidate cell is preferentially selected as the target cell under the condition that the signal quality of the first candidate cell meets the preset residence condition. If there is no configuration as described above, the second candidate cell is preferentially selected as the target cell.
And a second case: the second configuration information may include: and when the frequency priority of the candidate cell in the power saving mode is higher than that of the candidate cell in the non-power saving mode, preferentially selecting the candidate cell in the power saving mode.
Taking the first candidate cell and the second candidate cell as examples, if the frequency priority of the first candidate cell is higher than that of the second candidate cell, and the first candidate cell is in the power saving mode, the second candidate cell is in a normal state, and the first candidate cell is preferentially selected as the target cell under the condition that the signal quality of the first candidate cell meets the preset residence condition. If there is no configuration as described above, the second candidate cell is preferentially selected as the target cell.
And a third case: if the frequency priority of the candidate cell in the power saving mode is lower than that of the candidate cell in the non-power saving mode, the candidate cell in the non-power saving mode is preferentially selected.
Taking the first candidate cell and the second candidate cell as examples, if the frequency priority of the first candidate cell is lower than that of the second candidate cell, and the first candidate cell is in the power saving mode and the second candidate cell is in the normal state, the second candidate cell is preferentially selected as the target cell.
In other words, in the solution of the embodiment of the present application, if the frequency priority of the serving cell in the power saving mode is lower than the frequency priority of the candidate cell in the non-power saving mode, the terminal still selects the cell camping in the non-power saving mode even if the terminal is preconfigured to preferentially select the candidate cell in the power saving mode. That is, the terminal preferentially selects the cell in the power saving mode only in the case where the frequency priorities of the cells in the power saving mode are the same or higher.
Further, if the network does not pre-configure the terminal to preferentially select the candidate cell in the power saving mode as the target cell, the terminal always selects the candidate cell in the non-power saving mode. For example, the terminal may select a cell with the highest frequency priority among candidate cells in the non-power saving mode as the target cell.
By the method, the network can comprehensively manage the load and the power saving requirement of a plurality of candidate cells, and the terminal can select a proper target cell from the plurality of candidate cells to reside by configuring whether the terminal prefers the cell in the power saving mode or not so as to meet the requirements of power saving and load balancing.
