Detailed Description
Before the technical solutions of the present application are introduced, the related concepts referred to in the present application are now introduced:
code Division Multiple Access (CDMA): the principle of CDMA technology is based on spread spectrum technology, i.e. the information data with a certain signal bandwidth to be transmitted is modulated by a high-speed pseudo-random code whose bandwidth is far greater than that of signal bandwidth, so that the bandwidth of original data signal is expanded, then modulated by carrier wave and sent out.
New Radio (NR): defined as a fifth generation mobile communication system, has been currently subjected to two versions, Rel-15 and Rel-16.
Synchronization Signal block (Synchronization Signal and PBCH block, SSB): the Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and Physical Broadcast Channel (PBCH) are used.
Master Information Block (MIB): transmitted on the physical broadcast channel PBCH, which contains part of the information for cell access.
Physical Broadcast Channel (PBCH): and the broadcast channel is used for carrying the MIB.
Synchronization Raster (Synch Raster): according to a predefined frequency domain position, a terminal searches and scans SSBs on a predefined synchronization grid to access a cell and acquire cell information of a target cell, and the step size and the density of the synchronization grid determine the time for the terminal to perform initial cell search.
Band (band): a transceiver device may simultaneously communicate over a block of frequency domain.
When a terminal supporting multiple networks performs cell search, it may search for an SSB corresponding to any one of the multiple networks and camp on a cell corresponding to the SSB. The prior art does not limit the technical solutions for the terminal to access the cells of a specific network or networks in the above-mentioned multiple networks.
In order to solve the problem that a terminal accesses a target network (e.g., a GSM network) in the cell access process, embodiments of the present application provide a technical solution for limiting the terminal to access a cell of the target network.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The embodiment of the present application provides a cell access method, which is applied to a terminal in communication with a network side, and it can be understood that the terminal may refer to an access terminal, a User Equipment (UE), a remote device, a mobile device, a User terminal, a subscriber unit, a mobile terminal, a wireless communication device, a User agent, a User Equipment, a subscriber station, a mobile station, a remote station, and the like. The terminal may specifically be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a PLMN evolved in the future, and the like. For convenience of description, the embodiments of the present application take a terminal as an example to perform the following description.
Fig. 1 is a schematic flow chart of a cell access method provided in an embodiment of the present application, and as shown in fig. 1, the method includes:
step 101: and executing cell search, and reselecting other cells to be accessed if the network where the cells to be accessed are located is the target network.
In a specific implementation process, before a terminal accesses a cell, the terminal needs to perform cell search on a frequency band supported by the terminal, so as to determine a cell to be accessed. The target network is a pre-specified network, and may specifically be a specified network type or a specified network type, for example: 2G networks, 3G networks, GSM networks, GPRS networks, etc. If the network where the cell to be accessed is located is the target network, the terminal is not allowed to camp on the cell under the target network, and cells under other non-target networks need to be reselected, so that the terminal is camped on the cells under the non-target networks.
In the embodiment of the application, when the network corresponding to the cell to be accessed is the target network, other cells to be accessed are reselected, so that the terminal is limited to stay in the cell under the target network.
On the basis of the above embodiment, the steps of the method for the terminal to perform cell search are shown in fig. 2:
step 201: after the terminal starts the network function, the terminal searches and scans SSB on a predefined synchronous grid for each band and acquires cell information of a cell to be accessed.
Step 202: after acquiring the SSB, the terminal demodulates the SSB.
Step 203: the terminal demodulates the system information block; the terminal may acquire specific Information of the target cell, including Information of the accessed network, by demodulating System Information Block 1 (SIB 1). Specifically, the SIB1 may be composed into a system message together with MIB information and transmitted in a broadcast form.
On the basis of the above embodiment, when the network where the cell to be accessed is located is the target network, the terminal may actively select the cell access in the non-target network, or may passively select the cell access in the non-target network. In the following, the embodiments of the present application are described in terms of passive and active selection of a cell of a non-target network by a terminal for access.
In a first aspect, a terminal passively selects cell access of a non-target network
After the terminal executes the cell search and obtains the cell information of the cell to be accessed, the terminal sends a request for accessing the cell to be accessed to the base station. And after receiving the request, the base station judges whether the network of the cell to be accessed is a target network, and if the network of the cell to be accessed is the target network, the base station sends indication information to the terminal, wherein the indication information is used for indicating whether the network of the cell to be accessed is the target network. Specifically, the indication information is used to indicate whether a network type of the cell to be accessed is a target network type, or to indicate whether a network type of the cell to be accessed is the target network type.
It is understood that the base station may indicate the terminal through a message form like "short message", for example, that the current network is the XX network and does not support the condition of accessing the cell. In addition, the base station may also configure signaling containing the indication information separately, put the signaling in a broadcast message, and send the signaling to the terminal in a broadcast or unicast or multicast mode. The base station may also send the indication information to the terminal in other forms, and the embodiment of the present application does not limit the sending form of the indication information.
In addition, after receiving the indication information sent by the base station, the terminal may reselect another cell to be accessed in the following manner:
the first method is as follows: and the terminal continues to search the SSBs on the predefined frequency band and demodulates the target SSB based on the searched SSBs to obtain the cell information of other cells to be accessed.
The second method comprises the following steps: and searching other cells to be accessed outside the frequency range corresponding to the target network.
Since the network in which the cell to be accessed is located is the target network, the terminal may search for the SSB in the frequency band supported by the terminal except for the frequency band range corresponding to the target network, so as to obtain the cell information of other cells to be accessed in the non-target network.
The third method comprises the following steps: and determining other cells to be accessed according to the pre-stored information.
The pre-stored information includes the SSB cached by the terminal, where the SSB is obtained by scanning the terminal on the supported frequency band before. Specifically, the terminal may select one SSB from a plurality of pre-stored SSBs to demodulate, and obtain cell information of other cells to be accessed. Therefore, after receiving the indication information sent by the base station, the terminal does not perform the step of SSB search, but acquires the SSBs of other cells to be accessed, except the SSB where the cell to be accessed is located, from the pre-stored information to obtain the cell information of the other cells to be accessed.
It is understood that the terminal may select one of the other SSBs that satisfies the energy threshold requirement when selecting the other SSBs. Of course, other SSBs that meet the energy threshold requirement and have the greatest energy may also be selected. Wherein the energy threshold requirement may be that the received signal power of the SSB is greater than a threshold. In addition, if all SSBs do not meet the energy threshold requirement, the terminal may randomly select one SSB for demodulation.
In the embodiment of the application, if the network where the cell to be accessed is located is the target network, the terminal determines other cells to be accessed in the pre-stored information, so that the step of frequency sweeping again is omitted, and the efficiency of determining other cells to be accessed is improved.
On the basis of the above embodiment, the base station sends the indication information to the terminal after judging whether the network where the cell to be accessed is located is the target network. After the terminal receives the indication information, and the indication information indicates that the network where the cell to be accessed is located is not the target network, the terminal is camped in the cell to be accessed. The base station determines whether a network in which the cell to be accessed is located is a target network, and specifically may be: the base station judges whether the network type of the cell to be accessed is a target network type or not, or whether the network type of the cell to be accessed is the target network type or not.
It should be noted that the base station may indicate to the terminal "you will access the XX network in the form of a message like" short message ". In addition, the base station may also configure signaling containing the indication information separately, put the signaling in a broadcast message, and send the signaling to the terminal in a broadcast or unicast or multicast mode. The base station may also send the indication information to the terminal in other forms, and the embodiment of the present application does not limit the sending form of the indication information.
The method and the device for determining the cell to be accessed determine whether a network where the cell to be accessed is located is a target network or not through a base station, and send indication information to a terminal to indicate whether the network where the cell to be accessed is located is the target network or not, and when the indication information represents that the network where the cell to be accessed is located is the target network, the terminal is not allowed to be accessed to the cell to be accessed, so that the terminal is limited to be accessed to the cell under the target network.
In a second aspect, a terminal actively selects cell access of a non-target network
The terminal actively judges whether the network where the cell to be accessed is located is a target network, and reselects other cells to be accessed if the network is the target network.
The terminal can judge whether the network corresponding to the cell to be accessed is a target network or not through the following modes:
the first method is as follows: the terminal acquires the network information of the cell to be accessed, and determines whether the network in which the cell to be accessed is located is a target network or not according to the network information. The target Network can be distinguished by Public Land Mobile Network (PLMN) ID, and the terminal can determine the Network where the cell to be accessed is located through the PLMN ID because the PLMN IDs under different networks are different. Taking Long Term Evolution (LTE) system or NR system as an example, the PLMN ID is located in SIB1, and the terminal may obtain the PLMN ID by demodulating SIB 1.
The second method comprises the following steps: and the terminal determines whether the network of the cell to be accessed is a target network according to the frequency point information of the cell to be accessed. Because the frequency ranges of the networks of different systems are different, for example, the downlink frequency range of the GSM network for china mobile is 935MHz (megahertz) -954MHz, and the frequency range of LTE can be 1880-1900MHz, 2320-2370MHz, 2575-2635 MHz. Therefore, the terminal can judge whether the cell to be accessed is under the target network according to the frequency point information to which the SSB belongs.
When the terminal judges that the network where the cell to be accessed is located is the target network, other cells to be accessed can be reselected in the following mode:
the first method is as follows: and the terminal continues to search the SSB on the predefined frequency band and demodulates based on the searched SSB to obtain the cell information of other cells to be accessed.
The second method comprises the following steps: and searching other cells to be accessed outside the frequency range corresponding to the target network.
Since the network in which the cell to be accessed is located is the target network, the terminal may search for the SSB in the frequency band supported by the terminal except for the frequency band range corresponding to the target network, so as to obtain the cell information of other cells to be accessed under the non-target network.
The third method comprises the following steps: and determining other cells to be accessed according to the pre-stored information.
The pre-stored information includes the SSB cached by the terminal, where the SSB is obtained by scanning the terminal on the supported frequency band before. Specifically, the terminal may select one SSB from a plurality of pre-stored SSBs to demodulate, and obtain cell information of other cells to be accessed. Therefore, the terminal does not perform the step of SSB search, but obtains the SSBs of other cells to be accessed besides the SSB in which the cell to be accessed is located from the pre-stored information to obtain the cell information of the other cells to be accessed.
It is understood that the terminal may select one of the other SSBs that satisfies the energy threshold requirement when selecting the other SSBs. Of course, other SSBs that meet the energy threshold requirement and have the greatest energy may also be selected. Wherein the energy threshold requirement may be that the received signal power of the SSB is greater than a threshold. In addition, if the energy of all SSBs does not meet the energy threshold requirement, the terminal may randomly select one SSB from the SSBs.
According to the embodiment of the application, when the terminal autonomously judges that the network where the cell to be accessed is located is the target network, the SSB search is carried out again, so that the terminal can be accessed to the cell under the non-target network.
It should be noted that, after the terminal successfully demodulates the message sent by the network side and before accessing the non-target network, the terminal may be in the following state:
(1) the idle state means that the terminal does not establish communication with the base station, and from the perspective of the core network, the terminal and the base station are in a network disconnection state.
(2) Inactive state, i.e. the terminal does not establish full communication with the base station, from the core network perspective, the terminal and the base station are in a network connection state.
On the basis of the above embodiment, after the terminal camps in the cell to be accessed, the terminal may obtain the cell information of other non-target networks in a scheduling request manner.
After the terminal successfully demodulates the information sent by the base station, the terminal can obtain the cell information of other non-target networks by initiating random access. It will be appreciated that cell information for non-target networks may be included in other system information blocks, such as SIBx.
Fig. 3 is a schematic flow chart of another cell access method provided in the embodiment of the present application, and as shown in fig. 3, the method is applied to a network side, for example: the base station may be a base station in a GSM system or a CDMA system, a base station in a WCDMA system, an evolved node base in an LTE system, or a base station in a 5G system. The method comprises the following steps:
step 301: receiving a request for accessing a cell to be accessed, which is sent by a terminal;
step 302: and sending indication information to the terminal, wherein the indication information is used for indicating whether the network where the cell to be accessed is located is a target network.
In a specific implementation process, the terminal obtains cell information of a cell to be accessed after cell search is performed, and sends a request for accessing the cell to be accessed to the base station. After receiving the request, the base station judges whether the network where the cell to be accessed is located is a target network, and sends indication information to the terminal. For the explanation of the target network, reference is made to the above embodiments, which are not described herein again.
It can be understood that, after receiving the indication information sent by the base station, if the indication information indicates that the network where the cell to be accessed is located is the target network, the terminal reselects another cell to be accessed. The method for reselecting other cells to be accessed refers to the above embodiments and is not described herein again.
On the basis of the above embodiment, the base station may further send cell information under a non-target network to the terminal, where the cell information may be configured in signaling, for example: the cell information may be configured in Radio Resource Control (RRC) signaling.
For convenience of understanding, the embodiments of the present application are described with respect to a terminal passively reselecting a cell to be accessed and an terminal actively reselecting the cell to be accessed by taking a target network as a GSM network as an example.
Fig. 4 is a flowchart of cell access for a terminal to passively select a non-target network according to an embodiment of the present application, as shown in fig. 4:
step 401: after the terminal starts the network function, the terminal searches the synchronous signal on the predefined frequency domain position.
Step 402: after the terminal successfully demodulates the synchronization signal, the synchronization of the cell is completed, and the system information block broadcasted by the cell is continuously demodulated.
Step 403: the terminal demodulates the system information block (e.g., SIB1) to obtain cell information for the cell to be accessed.
Step 404: after obtaining the cell information of the cell to be accessed through cell search, the terminal sends a request for accessing the cell to be accessed to the base station.
Step 405: and the base station judges whether the network where the cell to be accessed is located is a GSM network.
Step 406: and the base station returns indication information to the terminal, wherein the indication information is used for indicating whether the network of the cell to be accessed is a GSM network.
Step 407: if the indication information indicates that the network where the cell to be accessed is located is a GSM network, the base station does not allow the terminal to access the cell, and the terminal reselects another cell to be accessed, that is, the step 401 is returned to search for another synchronization signal in the predefined frequency domain position, and when another synchronization signal is searched, the subsequent steps such as the step 402 and the like are continuously executed.
Step 408: and if the indication information represents that the network of the cell to be accessed is not the GSM network, the terminal is resided in the cell.
Fig. 5 is a flowchart of a cell access process for a terminal to actively select a non-target network according to an embodiment of the present application, as shown in fig. 5:
step 501: after the terminal starts the network function, the terminal searches the synchronous signal at the predefined frequency domain position.
Step 502: after the terminal successfully demodulates the synchronization signal, the synchronization of the cell is completed, and the system information block broadcasted by the cell is continuously demodulated.
Step 503: the terminal demodulates the system information block (e.g., SIB1) to obtain cell information of the cell to be accessed.
Step 504: the terminal judges whether the network of the cell to be accessed is a GSM network; if the cell is the GSM network, the terminal reselects other cells to be accessed, namely, the terminal returns to the step 501 to search other synchronous signals in the predefined frequency domain position, and continues to execute the subsequent steps such as the step 502 and the like after the other synchronous signals are searched; otherwise, step 505 is performed. The method for determining whether the GSM network is used is described in the above embodiments, and details are not repeated here. The predefined frequency domain position includes a plurality of frequency bands, and therefore, searching for other synchronization signals in the predefined frequency domain position may specifically be searching for synchronization signals in other frequency bands except for the frequency band corresponding to the GSM network.
Step 505: and the terminal is resided in the cell to be accessed.
Step 506: the terminal searches for cell information of other non-GSM networks to camp on the cell.
It should be noted that, in practical application, when a terminal performs cell reselection or handover, if it is determined that a network in which a cell to be camped is located is a target network, the terminal does not camp in the cell. Further, step 506 may be located before or after any of steps 501-505.
