Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, a terminal often needs to communicate through a network. For example, NSA (Non-standard one, non-independent networking) or other networks. In the whole call process, according to the call service requirement, the terminal may need to perform network handover to register from one network to a cell of another network, so as to obtain better call quality.
The present disclosure provides a cell registration method. Fig. 1 is a first flowchart illustrating a cell registration method according to an example embodiment. As shown in fig. 1, the cell registration method is applied to a user equipment UE, and includes:
and step 12, responding to the successful search of the second type of cells according to the frequency point information of the second type of cells, and registering the cells to the second type of cells according to the service transmission condition of the first type of cells.
In the embodiment of the disclosure, the cell registration method can be applied to the inter-cell return of the user equipment UE in the network based on two different system bandwidths. For example, to a NSA network or SA network.
Illustratively, the first type of cells corresponds to LET cells (cells in a 4G network) and the second type of cells corresponds to NR cells (cells in a 5G network). The NR cell supports a system bandwidth that is greater than that of the LET cell. Or the like, or a combination thereof,
the method is applied to the return of the user equipment UE from the 3G cell to the 4G cell, wherein the first type cell corresponds to the 3G cell, and the second type cell can be an LET cell.
The service transmission situation on the first type cell comprises at least one of the following conditions:
a voice service transmission situation on the first type cell;
traffic transmission over the first type of cell.
Voice data is transmitted by voice service; traffic data transmitted by the traffic service.
In the embodiment of the present disclosure, before the cell registration method is specifically applied, when a UE is talking on the basis of an NSA network, the UE may first initiate a call in a 5G NR network, and store frequency point information of an NR cell. When a call is made in NSA, an EPS (Evolved Packet System) fallback scheme is used, and after the call is established, the UE is switched to the LTE network to perform the call. After the UE is registered to the LTE cell, the frequency point information of an NR adjacent cell (second type cell) of the LTE cell in an LTE system message (SIB 24) is read and stored. After the call is ended in NSA, the LTE network sends a connection release message (RCConnectionRelease) to the UE. The UE may obtain frequency point information of the NR cell from a connection release message (RCConnectionRelease) of the LTE network.
The frequency point information used for searching the second type of cell in the present application may be the frequency point information of any one of the above NR cells.
In the embodiment of the present disclosure, the UE may acquire the frequency point information of the NR cell stored when the 5G NR network initiates a call, may also acquire the frequency point information of the NR neighbor cell of the LTE cell stored in the call process, or acquire the frequency point information of the NR cell from the connection release message of the LTE network after the call is completed.
In the embodiment of the present disclosure, the UE may also obtain all frequency point information of the NR cell in the above 3 cases.
The frequency point information at least comprises a cell frequency point and a cell ID. Searching the second type cell according to the frequency point information of the second type cell, comprising: searching a corresponding transmission channel according to the cell frequency point, and determining a sector cell under the cell frequency point; and then the second type of cell is determined as a specific area corresponding to the ID in the sector cell by the cell ID. For example, it is determined by the cell frequency point that the sector cells under the frequency point include an area a, an area B, and an area C. And finally determining that the second type cell is the area A under the cell frequency point if the cell ID corresponds to the area A.
In the embodiment of the present disclosure, the service transmission condition on the first-type cell refers to whether the UE has traffic data to be transmitted on the first-type cell, where the traffic data to be transmitted at least includes two conditions of traffic data to be transmitted and no traffic data to be transmitted.
In the embodiment of the disclosure, the second-type cell is searched according to the frequency point information of the second-type cell, and the second-type cell is combined with the service transmission condition of the first-type cell. And searching the second type cell according to the acquired frequency point information of the second type cell by successfully acquiring the frequency point information of the second type cell. And after the second type of cell is successfully searched, registering the second type of cell according to the service transmission condition of the first type of cell. Since the system bandwidth supported by the cells of the second type is larger than the system bandwidth of the cells of the first type. And searching a second type cell needing to be registered through the frequency point information, and registering the second type cell according to the service transmission condition of the first type cell, so that the UE can be registered to the second type cell as much as possible, and a higher-speed and higher-quality communication service is provided for the UE through the second type cell with a higher system bandwidth.
In some embodiments, the registering to the second type of cell according to the service transmission condition of the first type of cell includes:
searching the second type cell according to the frequency point information of the second type when no traffic data to be transmitted exists after the conversation on the first type cell is finished;
and/or the presence of a gas in the gas,
when traffic data to be transmitted exists after the call on the first type cell is finished, determining a time point for registering to the second type cell according to the data volume of the service traffic data to be transmitted and/or the attribute of the first type cell, and registering to the second type cell at the determined time point.
In the embodiment of the present disclosure, the service transmission condition of the first-class cell includes that there is no traffic data to be transmitted after the call on the first-class cell is ended, or there is traffic data to be transmitted after the call on the first-class cell is ended.
When it is determined that no traffic data to be transmitted exists after the call on the first-class cell is ended, searching a second-class cell for registration according to the frequency point information of the second class; when the traffic data to be transmitted exists after the call on the first-class cell is finished, determining a time point for registering to a second-class cell according to the data volume of the traffic data to be transmitted and/or the attribute of the first-class cell, and registering to the second-class cell at the determined time point.
According to the method and the device, when no to-be-transmitted flow data exists, the second type cell is searched according to the second type frequency point information to be registered, so that the UE can be registered to the searched second type cell after the conversation is finished and under the condition that no to-be-transmitted flow data exists, the returning efficiency of returning to the second type cell is improved, and the user experience is improved.
When the traffic data is to be transmitted, the registration time point is determined according to the data volume of the traffic data to be transmitted and/or the attribute of the first cell, and then the second cell is returned according to the determined time point.
In some embodiments of the present invention, the,
when traffic data to be transmitted exists after the call on the first-class cell is finished, determining a time point for registering to the second-class cell according to the data volume of the traffic data to be transmitted and/or the attribute of the first-class cell, wherein the time point comprises at least one of the following:
when the traffic data to be transmitted exists after the call on the first-class cell is finished and the attribute of the first-class cell is determined to be the anchor point cell of the UE, determining that the time point registered to the second-class cell is after the call is finished;
and when the traffic data to be transmitted exists after the call on the first-class cell is finished and the attribute of the first-class cell determines that the traffic data to be transmitted is not the anchor cell of the UE, determining a time point for registering the traffic data to be transmitted to the second-class cell according to the data volume of the traffic data to be transmitted.
In the embodiment of the disclosure, when the first-class cell has traffic data to be transmitted after the call is ended, the time point of cell registration needs to be determined to clarify the cell return time, so that the situation of blind and ultra-long waiting when a large amount of traffic data to be transmitted exists is avoided, and therefore the UE is allowed to register to the second-class cell earlier, and the residence time of the UE in the second-class cell is increased. The determination method of the cell registration time point mainly includes two situations that the first type cell is an anchor cell of the UE and the first type cell is not the anchor cell of the UE. The situation that the first type cell is not the anchor cell of the UE is divided into two situations according to the data size of the traffic data to be transmitted.
In the present application, an anchor cell is a cell in an LTE network, for which an NR cell can be configured to access an NR network. When the first type cell is determined to be the anchor cell of the UE, the network may configure an NR cell for the LTE cell. After the NR cell is configured, the UE can be directly connected to the NR cell and then performs data transmission through the NR network, thereby saving the waiting time required by data transmission and extracting and returning the data to the NR cell.
The specific configuration process of the NR cell is as follows:
and the UE reads measConfiguration measurement configuration information in RRC ConnectionReconfiguration connection reconfiguration information sent to the UE by the network, and measures the NR cell in the measConfiguration.
If the condition in the measConfig (here, the condition refers to a rule defined by a reportConfigId in the measConfig) is met, reporting a measurement report of measurementreeport to the network, and then adding a second type of cell (NR cell) for the UE by the network side for registration.
After the configuration is completed, the UE simultaneously transmits data with the LTE cell and the NR cell until the data transmission is completed.
In summary, when it is determined that the first-class cell is the anchor cell of the UE, the time point of registering to the second-class cell is determined as when the network end completes adding the NR cell to the UE after the call is completed, so that cell registration does not need to be performed until data transmission is completed, and the return efficiency of returning to the second-class cell is further improved.
In the method, when the first-class cell is determined not to be the anchor cell of the UE, the time point of registering the first-class cell to the second-class cell can be determined according to the data volume of the traffic data to be transmitted, so that the condition of blind and overlong waiting when a large amount of traffic data to be transmitted exists is reduced, and the user experience is improved.
In some embodiments, when the attribute of the first type cell determines that the first type cell is not an anchor cell of the UE, determining a time point for registering to the second type cell according to the data volume of the traffic data to be transmitted includes:
when the attribute of the first-class cell determines that the first-class cell is not the anchor cell of the UE and the data volume of the traffic data to be transmitted is smaller than a preset threshold value, determining that the time point registered to the second-class cell is after the transmission of the traffic data to be transmitted is completed on the first-class cell;
and/or the presence of a gas in the gas,
and when the attribute of the first type cell determines that the first type cell is not the anchor cell of the UE and the data volume of the flow data to be transmitted is equal to or larger than a preset threshold value, determining that the time point registered to the second type cell is after the call is finished.
In the embodiment of the present disclosure, for a situation that the first-class cell is not an anchor cell of the UE and traffic data to be transmitted exists, the data amount of the traffic data to be transmitted is compared with a preset threshold, so as to perform situation-based processing. When the data volume of the traffic data to be transmitted is smaller than the preset threshold, it is indicated that the data volume of the traffic data to be transmitted is smaller, and the time required for completing the transmission is shorter. At this time, the second type cell may be registered after transmission of traffic data to be transmitted. When the data volume of the traffic data to be transmitted is greater than the preset threshold, it indicates that the data volume of the traffic data to be transmitted is large, and the time required for completing transmission is long. If the user returns to the second cell after waiting for the completion of the data transmission, a long-time waiting situation may occur, which is obviously not favorable for improving the user experience. Therefore, when the amount of data to be transmitted is large, the cell of the second type can be returned after the call is ended, so that the situation of long-time waiting is reduced.
In the embodiment of the disclosure, when the data volume of the traffic data to be transmitted is smaller than the preset threshold, after the traffic data to be transmitted is transmitted, the second-class cell is searched through the frequency point information of the second-class cell to perform cell registration.
In the embodiment of the present disclosure, when the data amount of the traffic data to be transmitted is greater than the preset threshold, after the call is ended, the second type cell may be switched to by performing a data service to a handover (that is, PS handover to 5G).
In some embodiments, the registering with the second type of cell further comprises:
in response to the first type of cell being an anchor cell for the UE, connecting to the second type of cell associated with the anchor cell;
and/or the presence of a gas in the gas,
and registering to the second type of cell in a cell reselection mode in response to the first type of cell not being an anchor cell of the UE.
In the embodiment of the present disclosure, when it is determined that the first type cell is an anchor cell of the UE, the network configures a second type cell (NR cell) for the UE to register.
In the embodiment of the disclosure, when it is determined that the first type cell is not the anchor cell of the UE, the cell reselection mode is registered to the second type cell. The first-class cells are divided into anchor cells and non-anchor cells according to the attribute judgment so as to register the cells in different modes, and the returning efficiency of returning to the second-class cells is improved according to different conditions.
In some embodiments, the frequency point information of the second type cell includes at least one of:
the frequency point information of the second type cell is stored when the call is initiated on the second type cell;
reading the frequency point information of the second type cell in a system message block of the first type cell;
and reading the frequency point information of the second type cell in the connection release message of the first type cell.
In this embodiment, the frequency point information of the second type cell may include at least one of frequency point information of the second type cell stored when a call is initiated on the second type cell, frequency point information of the second type cell read in a system message block of the first type cell, and frequency point information of the second type cell read in a connection release message of the first type cell. The second type of cells can be searched through any one of the frequency point information, so that the success rate of searching the second type of cells is improved.

and step 23, storing the frequency point information Freq _ NR _1 of the NR cell carried in the RRC Connection Release message sent by the LTE network after the call is finished.

step 33, judging whether an NR cell is searched, registering the NR cell when the NR cell is searched, and otherwise, searching the NR cell by using frequency point information Freq _ NR;
step 34, judging whether an NR cell is searched, registering the NR cell when the NR cell is searched, and otherwise, searching the NR cell by using frequency point information Freq _ NR _ list;
And step 36, judging that the LTE cell is an anchor cell, displaying 5G by adopting a configD display scheme, and returning to the NR cell through cell reselection if the LTE cell is not the anchor cell.
judging that the LTE cell is an anchor cell, displaying 5G by adopting a configD display scheme, otherwise, comparing the data volume to be transmitted with a preset threshold value, and executing the data service to a 5G handover (namely PS handover to 5G) when the data volume to be transmitted is larger than the preset threshold value; and when the data transmission rate is smaller than the preset threshold value, the data is registered to the NR cell through frequency point information search after the data transmission is finished.
In a second aspect of the embodiments of the present disclosure, a cell registration apparatus is provided. Fig. 4 is a schematic structural diagram illustrating a cell registration apparatus according to an exemplary embodiment. As shown in fig. 4, the cell registration apparatus is applied in a user equipment UE, and includes:

and a third processing device 43, configured to respond to successfully searching for the second-type cell according to the frequency point information of the second-type cell, and register the second-type cell according to the service transmission condition of the first-type cell.
In the embodiment of the present disclosure, the cell registration apparatus may be applied to inter-cell return in a network based on two different system bandwidths for the UE. For example, to an NSA network or an SA network.
Illustratively, the first type of cells corresponds to LET cells (cells in a 4G network) and the second type of cells corresponds to NR cells (cells in a 5G network). The NR cell supports a system bandwidth greater than that of the LET cell. Or the like, or, alternatively,
the method is applied to the return of the user equipment UE from the 3G cell to the 4G cell, wherein the first type cell corresponds to the 3G cell, and the second type cell can be an LET cell.

In this embodiment of the present disclosure, before the cell registration apparatus is specifically applied, when a UE is talking on the basis of an NSA network, the UE may first initiate a call in a 5G NR network, and store frequency point information of an NR cell. Because an EPS (Evolved Packet System) fallback scheme is adopted during the call in the NSA, after the call is established, the UE may be switched to the LTE network to perform the call. And after the UE is registered to the LTE cell, reading and storing the frequency point information of the NR adjacent cell (second-class cell) of the LTE cell in the LTE system message (SIB 24). After the call is ended in NSA, the LTE network sends a connection release message (RCConnectionRelease) to the UE.

For example, it is determined through the cell frequency point that the sector cells under the frequency point include an area a, an area B, and an area C. And finally determining the second type of cell as the area A under the cell frequency point if the cell ID corresponds to the area A.

And after the second type of cell is successfully searched, registering the second type of cell according to the service transmission condition of the first type of cell. Since the system bandwidth supported by the cells of the second type is larger than the system bandwidth of the cells of the first type. And searching a second type cell needing to be registered through the frequency point information, and registering the second type cell according to the service transmission condition of the first type cell, so that the UE can be registered to the second type cell as much as possible, and a higher-speed and higher-quality communication service is provided for the UE through the second type cell with a higher system bandwidth.
In some embodiments, the third processing device is configured to register to the second type of cell according to a service transmission condition of the first type of cell, and includes:
the third processing device is specifically configured to search the second-class cell according to the second-class frequency point information when there is no traffic data to be transmitted after the call on the first-class cell is ended;
and/or the presence of a gas in the gas,
when traffic data to be transmitted exists after the call on the first-class cell is finished, determining a time point for registering to the second-class cell according to the data volume of the traffic data to be transmitted and/or the attribute of the first-class cell, and registering to the second-class cell at the determined time point.
In the embodiment of the present disclosure, the service transmission condition of the first-class cell includes that there is no traffic data to be transmitted after the call on the first-class cell is ended, or there is traffic data to be transmitted after the call on the first-class cell is ended.
When it is determined that no traffic data to be transmitted exists after the call on the first-class cell is ended, searching a second-class cell for registration according to the frequency point information of the second class; when the traffic data to be transmitted exists after the call on the first-class cell is finished, determining a time point for registering to a second-class cell according to the data volume of the traffic data to be transmitted and/or the attribute of the first-class cell, and registering to the second-class cell at the determined time point.
According to the method and the device, when no to-be-transmitted flow data exists, the second type cell is searched according to the frequency point information of the second type to be registered, so that the UE can be registered to the searched second type cell after the conversation is finished and under the condition that no to-be-transmitted flow data exists, the returning efficiency of returning to the second type cell is improved, and the user experience is improved.
When the traffic data is to be transmitted, the registration time point is determined according to the data volume of the traffic data to be transmitted and/or the attribute of the first cell, and then the second cell is returned according to the determined time point.
In some embodiments, the third processing device is configured to, when traffic data to be transmitted exists after a call on the first-class cell is ended, determine, according to a data amount of the traffic data to be transmitted and/or an attribute of the first-class cell, a time point for registering to the second-class cell, where the time point includes at least one of:
the third processing device is specifically configured to determine that a time point when the UE registers in the second cell is after the call is ended when traffic data to be transmitted exists after the call in the first cell is ended and the attribute of the first cell determines that the traffic data is the anchor cell of the UE; and
and when the traffic data to be transmitted exists after the call on the first-class cell is finished and the attribute of the first-class cell determines that the traffic data to be transmitted is not the anchor cell of the UE, determining a time point for registering the traffic data to be transmitted to the second-class cell according to the data volume of the traffic data to be transmitted.
In the embodiment of the present disclosure, when there is traffic data to be transmitted after a call is ended, a time point of cell registration needs to be determined to clarify cell return time, so as to avoid a situation of blind and very long waiting when there is a large amount of traffic data to be transmitted, so that the UE is allowed to register to the second cell earlier, and the residence time of the UE in the second cell is increased. The determination method of the cell registration time point mainly includes two situations that the first type cell is an anchor cell of the UE and the first type cell is not the anchor cell of the UE. The situation that the first type cell is not the anchor cell of the UE is divided into two situations according to the data size of the traffic data to be transmitted.
In the present application, an anchor cell is a cell in an LTE network, for which an NR cell can be configured to access an NR network. When the first type cell is determined to be an anchor cell of the UE, the network may configure an NR cell for the LTE cell. After the NR cell is configured, the UE can be directly connected to the NR cell and then performs data transmission through the NR network, thereby saving the waiting time required by data transmission and extracting and returning the data to the NR cell.
The specific configuration process of the NR cell is as follows:
and the UE reads measConfiguration measurement configuration information in RRC ConnectionReconfiguration connection reconfiguration information sent to the UE by the network, and measures the NR cell in the measConfiguration.
If the condition in the measConfig (here, the condition refers to a rule defined by a reportConfigId in the measConfig) is met, reporting a measurement report of measurementreeport to the network, and then adding a second type of cell (NR cell) for the UE by the network side for registration.
After configuration is completed, the UE can simultaneously transmit data with the LTE cell and the NR cell until the data transmission is completed.
In summary, when it is determined that the first type cell is the anchor point cell of the UE, it is determined that the time point of registering to the second type cell is after the call is completed, and the network end completes adding the NR cell for the UE, so that it is not necessary to wait until the data transmission is completed before cell registration is performed, and further, the return efficiency of returning to the second type cell is improved.
In the method and the device, when the first-class cell is determined not to be the anchor cell of the UE, the time point of the registration to the second-class cell can be determined according to the data volume of the traffic data to be transmitted, so that the condition of blind and ultra-long waiting when a large amount of traffic data to be transmitted exists is reduced, and the user experience is improved.
In some embodiments, the third processing device is configured to, when the attribute of the first type of cell determines that the first type of cell is not an anchor cell of the UE, determine a time point for registering to the second type of cell according to the data amount of the traffic data to be transmitted, and includes:
the third processing device is specifically configured to determine that a time point registered in the second-class cell is after transmission of the traffic data to be transmitted is completed on the first-class cell when the attribute of the first-class cell determines that the first-class cell is not an anchor cell of the UE and the data volume of the traffic data to be transmitted is smaller than a preset threshold;
and/or the presence of a gas in the atmosphere,
and when the attribute of the first type cell determines that the first type cell is not the anchor cell of the UE and the data volume of the flow data to be transmitted is equal to or larger than a preset threshold value, determining that the time point registered to the second type cell is after the call is finished.
In the embodiment of the present disclosure, for a situation that the first-class cell is not an anchor cell of the UE and traffic data to be transmitted exists, the data amount of the traffic data to be transmitted is compared with a preset threshold, so as to perform situation-based processing. When the data volume of the traffic data to be transmitted is smaller than the preset threshold, it is indicated that the data volume of the traffic data to be transmitted is smaller, and the time required for completing the transmission is shorter. At this time, the second type cell may be registered after transmission of traffic data to be transmitted. When the data volume of the traffic data to be transmitted is greater than the preset threshold, it indicates that the data volume of the traffic data to be transmitted is large, and the time required for completing transmission is long. If the user returns to the second cell after waiting for the completion of the data transmission, a long waiting time may occur, which is obviously not favorable for improving the user experience. Therefore, when the amount of data to be transmitted is large, the cell of the second type can be returned after the call is ended, so that the situation of long-time waiting is reduced.
In the embodiment of the disclosure, when the data volume of the traffic data to be transmitted is smaller than the preset threshold, after the traffic data to be transmitted is transmitted, the second-class cell is searched through the frequency point information of the second-class cell to perform cell registration.
In the embodiment of the present disclosure, when the data volume of the traffic data to be transmitted is greater than the preset threshold, after the call is ended, the cell may be switched to the second type cell in a manner of performing a data service to a 5G handover (i.e., PS handover to 5G).
In some embodiments, the third processing device is configured to register with the second type of cell, and further includes:
the third processing device is specifically configured to connect to the second type of cell associated with the anchor cell in response to the first type of cell being an anchor cell of the UE;
and/or the presence of a gas in the atmosphere,
and registering to the second type cell in a cell reselection mode in response to the first type cell not being an anchor cell of the UE.
In the embodiment of the present disclosure, when it is determined that the first type cell is an anchor cell of the UE, the network configures a second type cell (NR cell) for the UE to register.
In the embodiment of the present disclosure, when it is determined that the first-type cell is not the anchor cell of the UE, the cell reselection mode is registered to the second-type cell. The first-class cell is divided into the anchor cell and the non-anchor cell according to the attribute judgment so as to register the cells in different modes, and the returning efficiency of returning to the second-class cell is improved according to different conditions.
In some embodiments, the frequency point information of the second type cell includes at least one of:
the frequency point information of the second type cell is stored when the call is initiated on the second type cell;
