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.
The cell access method proposed in the present application is specifically described below. In the following embodiments of the present application, "and/or" describes an association relationship of associated objects, indicating that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first candidate cell and the second candidate cell are only for distinguishing different cells, and do not indicate a difference in priority, importance, or the like between the two cells.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically stated.
Referring to fig. 1, a schematic architecture diagram of a communication system provided in the present application is shown, it should be understood that the embodiments of the present application are not limited to the system shown in fig. 1, and furthermore, the apparatus in fig. 1 may be hardware, or may be a structure that is functionally divided into software, or a combination of the above two. As shown in fig. 1, a system architecture provided in the embodiment of the present application includes a terminal device and a base station. The number of the terminal devices and the base stations included in the system is not limited in the embodiments of the present application. Core network equipment, not shown in fig. 1, may also be included in the communication system.
A Terminal device, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a Mobile phone (Mobile phone), a tablet computer, a notebook computer, a palmtop computer, a Mobile Internet Device (MID), a wearable Device, a Virtual Reality (VR) Device, an Augmented Reality (AR) Device, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (city), a wireless terminal in smart home (smart home), and the like.
The base station related in the embodiment of the present application may also be referred to as a network device, AN Access Node, or AN Access Node (AN). The base station, namely the public mobile communication base station, is an interface device for the mobile terminal to access the internet. The base station may be specifically an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a base station equipment (gNB) in a 5G network, which is not limited in this application.
For example, the core Network device not shown in fig. 1 may include an Access and Mobility Management Entity (AMF), a Session Management Function (SMF), a Mobility Management Entity (MME), a Signaling Gateway (SGW), a public Data Gateway (PGW), and the like.
In one embodiment, the terminal device with DRX function may wake up and monitor the PDCCH channel to confirm whether there is a Paging (Paging) message at a set Paging Cycle (DRX Cycle) interval in the idle mode. Illustratively, referring to fig. 2, a paging mechanism for DXR according to an embodiment of the present application is provided. As shown in fig. 2, the terminal device is in a sleep state during Opportunity for DRX in one DRX paging cycle, and wakes up to monitor the PDCCH during On Duration. The maximum paging cycle in the DRX mode specified in the 3gpp TS 24.008 communication protocol is 2.56 seconds, that is, the terminal device wakes up once every 2.56 seconds, after waking up, the terminal device starts the radio frequency receiving function, receives the paging message from the base station, and the power consumption increases during the wake-up process.
In order to further reduce the power consumption of the terminal device, an eDRX function is proposed in the related art, which further increases the sleep time of the terminal device in an idle state on the basis of the DRX function, and reduces the number of awakening times, thereby reducing the power consumption of the terminal device. Exemplarily, referring to fig. 3, a paging mechanism for eDRX is provided in an embodiment of the present application. As shown in fig. 3, one Paging Cycle (eDRX Cycle) of eDRX of the terminal device includes a sleep Time and a Paging Time Window (PTW), where one PTW includes three On durations and two Opportunity for DRX. The maximum paging cycle in the eDRX mode specified in the 3GPP TS 24.008 communication protocol is 10485.76 seconds, which reduces the number of times that the terminal device is awakened and reduces the power consumption of the terminal device compared with DRX.
However, some base stations do not have eDRX function, and whether a base station has eDRX function or not is identified by relevant parameters in its broadcast signal, for example, according to eDRX-Allowed parameters included in SIB1 in at least one System Information Block (SIB) broadcast by the base station. Generally, when a terminal device connects to a base station, it selects a cell to be accessed based on the signal strength of the base station cell. For example, refer to fig. 4, which is a schematic diagram of a cell access process provided in the embodiment of the present application. It can be seen that, the existing terminal device will sequentially check whether each cell can be accessed according to the sequence of the signal strength of multiple cells capable of receiving signals, and select the first cell that passes the check for access. Based on such an access procedure, the terminal device may access a cell that does not support the eDRX function, and when the terminal device accesses the cell that does not support the eDRX function, the terminal device cannot consume power through the eDRX function.
In order to solve the above problems, the present application provides a cell access method, an apparatus, an electronic device, and a storage medium, which not only consider the signal strength factor of a cell but also consider whether the cell supports an eDRX function when selecting cell access, thereby improving the success rate of accessing a terminal device to a cell with the eDRX function. The scheme provided by the application can be applied to various scenes such as cell access, cell switching, redirection, reselection and the like.
Based on the system shown in fig. 1, the present application provides a cell access method, which may be implemented by a terminal device in the system shown in fig. 1. Optionally, referring to fig. 5, a flowchart of a cell access method provided in the embodiment of the present application may specifically include:
a terminal device receives system information from a plurality of candidate cells 501.
Wherein the system information is used for indicating whether the candidate cell supports the eDRX function.
502, the terminal device determines whether the candidate cells support the eDRX function according to the system information of the candidate cells.
Optionally, the terminal device may identify a cell supporting the eDRX function from among the candidate cells according to the received system information. For convenience of description, a cell supporting the eDRX function among the plurality of candidate cells is subsequently referred to as a first candidate cell. Optionally, the plurality of candidate cells may include one or more first candidate cells.
The terminal device determines a target cell from the plurality of candidate cells according to whether the plurality of candidate cells support the eDRX function 503.
As an alternative, the terminal device may determine the target cell according to the signal strength of one or more first candidate cells supporting the eDRX function in the multiple candidate cells. Optionally, the target cell may be a first candidate cell with the highest signal strength among the one or more first candidate cells.
And 504, the terminal equipment accesses the target cell.
Based on the above scheme, the present application provides a scheme for selecting an access cell, where a terminal device first determines a cell that can support an eDRX function from a plurality of candidate cells that can be searched, and then selects a cell to be accessed from the cells according to a signal strength of the cell that supports the eDRX function. Compared with the prior art that the terminal device selects the cell to be accessed only based on the signal strength of the cell, the purpose of reducing the power consumption through the eDRX function cannot be achieved, the success rate of accessing the terminal device to the cell supporting the eDRX function is improved, and therefore the power consumption of the terminal device can be reduced.
Optionally, when the terminal device determines the first candidate cell from the multiple candidate cells according to the system message, the terminal device may analyze the system message of each candidate cell, and determine whether any candidate cell is the first candidate cell according to a first parameter carried in the system message of any candidate cell.
In a possible implementation manner, when the first parameter carried in the system message of any candidate cell is a first value, the terminal device may determine that any candidate cell is the first candidate cell. When the first parameter carried in the system message of any candidate cell is the second value, the terminal device may determine that any candidate cell is not the first candidate cell.
In another possible implementation manner, when the system message of any candidate cell carries the first parameter, the terminal device may determine that any candidate cell is the first candidate cell. And when the system message of any candidate cell does not carry the first parameter, the terminal equipment determines that the any candidate cell is not the first candidate cell.
In another possible implementation manner, when the system message of any candidate cell carries the first parameter and the first parameter is a first value, the terminal device may determine that any candidate cell is the first candidate cell. And when any candidate cell does not carry the first parameter, the terminal equipment determines that the any candidate cell is not the first candidate cell. In some embodiments, the system message of any candidate cell may be SIB1 broadcasted by any candidate cell, and the first parameter may be an eDRX-Allowed parameter included in SIB 1. When the eDRX-Allowed parameter is set to true, the candidate cell is a first candidate cell and supports an eDRx function; when the SIB1 broadcasted by any candidate cell does not include the eDRX-Allowed parameter, it indicates that the candidate cell is not the first candidate cell.
In some embodiments, after identifying one or more first candidate cells supporting the eDRX function from the plurality of candidate cells according to broadcast signals of the plurality of candidate cells, the terminal device may determine a target cell with the largest signal strength among the one or more first candidate cells, and may regard the target cell as a cell to be accessed when the signal strength of the target cell is greater than a strength threshold. Alternatively, when determining that the Signal strength of the target cell is greater than the strength threshold, the terminal device may determine that the target cell meets the S criterion, for example, the Reference Signal Received Power (RSRP) of the broadcast Signal of the cell with the highest Signal strength is greater than a set Power threshold.
In other embodiments, after determining the target cell, if the signal strength of the target cell is not greater than the strength threshold, that is, the target cell does not meet the S criterion, the terminal device may access the candidate cell with the highest signal strength of the candidate cells.
Based on the description in the foregoing embodiments, the present application proposes that a cell may be first screened according to whether the cell supports the eDRX function, and one or more first candidate cells supporting the eDRX function are obtained. And according to the signal strength of one or more first candidate cells, taking the target cell which has the maximum signal strength and meets the S criterion as the cell to be accessed.
In some scenarios, the above operation of determining the target cell may also be implemented by various communication network layers of the terminal device. Alternatively, the terminal device may include a Physical Layer (PHY) for coding and decoding a transmission signal and a Radio Resource Control (RRC) Layer for managing and controlling Radio resources. Next, a process of selecting a cell to be accessed by the terminal device is specifically described in conjunction with each network layer included in the terminal device. Referring to fig. 6, a flowchart of a method for selecting an access cell provided in the embodiment of the present application specifically includes:
601, the RRC layer sends the searched access frequency point numbers of a plurality of candidate cells to the PHY layer.
Optionally, before transmitting the access frequency point numbers of the candidate cells, the RRC layer may classify the candidate cells according to whether the candidate cells support the eDRX function, and transmit the access frequency point numbers of the candidate cells included in each classified category to the PHY layer.
And 602, the PHY layer searches a set number of candidate cells according to the received access frequency point number and sends the broadcast information of the set number of candidate cells to the RRC layer.
Optionally, the broadcast Information of the candidate cell may include system Information of the candidate cell, such as Master Information Block (MIB) and SIB, where there may be multiple SIBs, and the multiple SIBs may include SIB1, SIB2, SIB3, and the like, and the SIB1 includes an eDRX Allowed parameter for characterizing whether the candidate cell supports the eDRX function.
603, the RRC layer sequences the candidate cells with the set number according to the eDRX capacity and the signal strength of the candidate cells with the set number, and determines a candidate cell sequence.
The candidate cell sequence comprises a first sequence and a second sequence, and the order of the first sequence is prior to that of the second sequence. The first sequence is obtained by sequencing the candidate cells supporting the eDRX function according to the signal strength of the candidate cells supporting the eDRX function. The second sequence is obtained by sequencing the candidate cells which do not support the eDRX function according to the signal intensity of the candidate cells which do not support the eDRX function.
604, the rrc layer extracts the first cell from the first sequence.
The first cell is a candidate cell at the first position in the first sequence.
Alternatively, after the RRC layer extracts the first cell from the first sequence, the extracted first cell may be deleted in the first sequence.
605, the rrc layer determines whether the first cell is in a forbidden access state.
If yes, go back to step 604.
If not, go on to step 606.
The rrc layer determines if the first cell is accessible 606.
Optionally, when determining whether the first cell is accessible, the RRC layer may determine whether the first cell is accessible by determining whether a Closed Subscriber Group (CSG) identifier maintained by the terminal device includes the CSG identifier of the first cell.
If yes, proceed to step 607.
If not, go back to step 604.
The rrc layer 607 determines if the first cell meets the public land mobile network and tracking area restrictions.
If yes, go to step 608.
If not, go back to step 604.
The rrc layer 608 determines whether the first cell meets the S criteria.
If yes, go to step 609.
If not, go back to step 604.
609, the RRC layer determines the first cell as a candidate cell for access.
Optionally, after determining the first cell to be accessed, the terminal device may send a connection request to the base station to which the first cell belongs, and receive a connection response returned by the base station. Wherein the connection response is used for indicating that the terminal equipment successfully accesses the first cell. In the following, a procedure for accessing the first cell by the terminal device is described with reference to a specific embodiment. Referring to fig. 7, a flowchart of a cell access method provided in the embodiment of the present application specifically includes:
701, a terminal device receives broadcast information of a first cell broadcast by a base station to which the first cell belongs.
And 702, the terminal equipment sends a random access request to the base station according to the broadcast information.
703, the base station receives the random access request and returns a random access response to the terminal device.
And 704, the terminal equipment receives the random access response and sends an RRC connection request to the base station.
705, the base station receives the RRC connection request and returns RRC connection configuration information to the terminal device.
The RRC connection configuration information is used to indicate that the base station and the terminal device successfully establish an RRC connection. Optionally, the RRC connection configuration information may also carry configuration information of a Signaling Radio Bearers (SRBs), an MAC layer, and a PHY layer.
And 706, the terminal equipment receives the RRC connection configuration information and sends RRC connection completion information to the base station.
The RRC connection complete information includes eDRX parameters of the terminal device, such as an eDRX paging cycle and a PTW of the terminal device.
707, the base station receives the RRC connection complete information and sends the RRC connection complete information to the core network device.
Optionally, the base station may transparently transmit the RRC connection complete information to the core network device.
And 708, the core network equipment receives the RRC connection completion information and returns parameter confirmation information to the base station.
709, the base station receives the parameter confirmation information and sends the parameter confirmation information to the terminal device.
And the terminal equipment receives the parameter confirmation information and determines the eDRX parameter configuration.
Optionally, after determining the eDRX parameter configuration, the terminal device may release the established RRC connection after detecting a set duration without signaling interaction with the base station, enter an idle mode, and start the eDRX mode according to the eDRX parameter configuration.
Optionally, in the above embodiment, the communication process between the terminal device and the base station may be implemented by an air interface (LTE User to Network interface unit, LTE-Uu) between the UE and the Network in the LTE Network.
In some embodiments, after accessing the first cell supporting the eDRX function, the terminal device may further store information of the first cell, so as to improve efficiency of subsequent cell selection. For example, when the terminal device determines that there is a stored first cell among the searched candidate cells, and the signal strength of the first cell is greater than the strength threshold, the terminal device may directly access the first cell.
As an alternative, the terminal device may store information of cells that support the eDRX function and that have successfully accessed in the form of a table. Optionally, the stored information of the cell may include a working frequency point of the cell, an identifier of the cell, and a storage time for storing the cell information.
Optionally, the terminal device may also sequence the stored cells according to the storage time of the stored cells, so as to implement management of the stored cells. For example, the terminal device determines the storage time of each cell, i.e., the time difference between the time of storing the cell information and the current time, according to the storage time of each cell. Further, the terminal device may determine an expired cell in each cell according to the storage time of each cell when the number of the stored cells is greater than the number threshold. The overdue cell is the cell with the longest storage time in each cell. The terminal device may delete the expired cells to save storage space.
