Detailed Description

The technical solution in the embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention.

Fig. 1 illustrates a wireless communication system 100. The wireless communication system 100 may include: a master network node (MN) 101, a secondary network node (SN) 103, one or more terminals 107, and a core network (core network) 105. The Dual Connectivity (DC) capability supported by the terminal 107 matches the dual connectivity capability supported by the main network node. The terminal 107 may establish a connection with the primary network node 101 and the secondary network node 103, respectively.

The primary network node 101 and the secondary network node 103 are network devices. Specifically, the main network node 101 (or the secondary network node 103) may be a Base Transceiver Station (BTS) in a time division synchronous code division multiple access (TD-SCDMA) system, or may be an evolved node B (eNB) in an LTE system, or a gb (next generation node B) in a 5G system or a new air interface (NR) system. In addition, the primary network node 101 (or secondary network node 103) may also be an Access Point (AP), a transmitting node (trans TRP), a Central Unit (CU) or other network entity, and may include some or all of the functionality of the above network entities.

Terminals 107 may be distributed throughout the wireless communication system 100 and may be stationary or mobile. In some embodiments of the present application, the terminal 107 may be a mobile device, mobile station (mobile station), mobile unit (mobile unit), M2M terminal, wireless unit, remote unit, user agent, mobile client, or the like. The terminal 107 may be a mobile phone, a tablet computer, a notebook computer, etc.

The primary network node 101 may transmit control plane data or user plane data to the core network 105 and the secondary network node 103 may transmit user plane data to the core network 105.

A group of serving/communication cells associated with the master network node 101 and/or provided or served by the master network node 101 may be referred to as a Master Cell Group (MCG), which comprises at least one cell. The group of serving/communication cells associated with the secondary network node 103 and/or provided or served by the primary network node 101 may be referred to as a Secondary Cell Group (SCG), which comprises at least one cell. In the embodiment of the present application, a cell in the MCG may be referred to as a primary cell, and a cell in the SCG may be referred to as a secondary cell.

Bearer (bearer) refers to a logical path between the core network 105 and the terminal equipment 107. The data flow or data transmission path between the core network 105 and the terminal device 107 is based on the logical concept of bearer (bearer). In the dual connectivity scenario, the bearer (bearer) has 3 different types: a master cell group bearer (MCG bearer), a secondary cell group bearer (SCG bearer), and a split bearer (split bearer).

For a terminal, not any cell may add a secondary cell to it. Even in the wireless communication system 100, the terminal must first register with the primary cell, and then the primary network node 101 determines whether there is a cooperative secondary cell in the cell where the terminal currently resides. When a cooperative secondary cell exists in the cell where the terminal currently resides, the primary network node 101 queries the dual connectivity capability supported by the terminal. When the dual connectivity supported by the terminal matches the dual connectivity supported by the master network node 101, the master network node 101 requests the terminal to measure the cell in which the terminal currently resides in cooperation with the secondary cell. The terminal reports the measurement result to the master network node 101 so that the master network node 101 makes a judgment to add the secondary cell to the terminal.

Next, the radio communication system 100 will be specifically described by taking EN-DC as an example.

In an EN-DC scenario, the primary network node 101 may be an eNB in a 4G communication system, the secondary network node 103 may be a gNB in a 5G or NR communication system, and the core network 105 may be an Evolved Packet Core (EPC). The eNB as the primary network node may be referred to as menb (master eNB), and the gNB as the secondary network node may be referred to as sgnb (secondary gNB). The EPC includes network elements such as a Mobility Management Entity (MME), a serving gateway (S-GW). Referring to fig. 2, control plane data may be transmitted between the eNB and the EPC, the gNB, and the terminal, user plane data may be transmitted between the eNB and the gNB, and the terminal, and user plane data may be transmitted between gNR and the terminal and the EPC.

The 5G/4G network protocol stack includes a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a physical layer (PHY) layer. In the EN-DC scenario, referring to fig. 3, for the MCG bearer, the data processed by the 4G (E-UTRA) PDCP module and the 5G (nr) PDCP module of the terminal are transferred to the 4G RLC module, the 4G MAC module and the terminal for processing, in other words, in the EN-DC scenario, the MCG bearer is based on the 4G module. For the SCG bearer, the data of the SCG bearer is processed by the 5G module from the 5G PDCP module, the 5G RLC module, and the 5G MAC module, that is, the SCG bearer is based on the 5G module. And splitting the bearer, wherein data of the split bearer is processed by a 5G PDCP module of the terminal and then transferred to a 4G RLC module, a 5G RLC module, a 4G MAC module and a 5G MAC module for processing respectively.

In an EN-DC scenario, a terminal needs to register to a cell corresponding to an MeNB, i.e., a primary cell (which may also be referred to as a 4G cell), and then the MeNB determines whether a cell in which the terminal currently resides has a cooperative secondary cell. The secondary cell, i.e. the cell corresponding to the SgNB, may also be referred to as a 5G cell. And when the cell where the terminal currently resides has the cooperative auxiliary cell, the MeNB inquires the dual connectivity supported by the terminal. And when the dual connection capability supported by the terminal is matched with the dual connection capability supported by the MeNB, the MeNB requests the terminal to measure the cell where the terminal currently resides in cooperation with the auxiliary cell. And the terminal reports the measurement result to the MeNB to enable the MeNB to judge so as to add the auxiliary cell for the terminal.

The procedure of adding the secondary cell to the terminal by the MeNB is shown in fig. 4 and includes the following steps.

401. The MeNB sends an addition request (addition request) from the SgNB to the SgNB;

402. the SgNB adds a request acknowledgement message (addition request acknowledge) to the MeNB;

403. the MeNB transmits a Radio Resource Control (RRC) connection reconfiguration request to the terminal;

404. the terminal sends an RRC reconfiguration complete (connection reconfiguration complete) message to the MeNB;

405. the MeNB sends a SgNB reconfiguration complete (reconfiguration complete) message to the SgNB;

406. a random access procedure (random access procedure) is carried out between the terminal and the SgNB;

Wherein, for the terminal, it learns that its current camping cell can add a secondary cell to the terminal through step 406.

When the terminal is in a network environment of multiple primary cells, in one scheme, the terminal determines to register the primary cell according to the signal quality of the primary cell, and then determines whether a secondary cell can be added. Referring to fig. 5, after the terminal successfully registers the primary cell, it determines whether the secondary cell can be added. And adding the auxiliary cell to the terminal by the main cell. And if the auxiliary cell can not be added, not adding the auxiliary cell for the terminal. And when the signal intensity of other main cells meets the cell switching threshold, carrying out cell switching, and then judging whether the switched cell can add an auxiliary cell for the terminal. It can be seen that, in this scheme, the terminal cannot be preferentially registered with the primary cell to which the secondary cell can be added for the terminal, and particularly, in an EN-DC scenario, the terminal cannot be preferentially registered with the 4G cell to which the 5G cell can be added for the terminal. When the terminal is registered in the 4G cell which can not add the 5G cell for the terminal and the signal intensity of other cells does not meet the cell switching threshold, the terminal has no chance to switch to the 4G cell which can add the 5G cell for the terminal, and the terminal can not enjoy the high-rate service.

The embodiment of the application provides a cell registration method, and an execution main body of the cell registration method is a terminal supporting double connection capacity. The terminal can preferentially register or switch to the cell which can add the auxiliary cell for the terminal according to the information of the history registration cell. Next, in different embodiments, a cell registration method provided in the embodiments of the present application is described in conjunction with different application scenarios.

The embodiment of the application provides a cell registration method, and an execution main body of the cell registration method is a terminal supporting double connection capacity. Referring to fig. 6, when the terminal does not yet camp on a cell and is about to perform cell registration, the terminal may perform step 600.

Step 600, scanning historical frequency points corresponding to the historical registered cells.

In this embodiment, if not specifically stated, the history registration cell of the terminal is a primary cell that is used for history registration of the terminal and to which a secondary cell can be added for the terminal.

In some embodiments, the terminal has an EN-DC capability, the primary cell is specifically a 4G cell in an EN-DC scenario, and the secondary cell is specifically a 5G cell in an EN-DC scenario.

The terminal may record a cell identity (cell identity) and a corresponding historical frequency point of a cell (i.e., a history registered cell) to which a secondary cell may be added in the history registered cells, and store the cell identity and the corresponding historical frequency point as feature information of the cell locally. The characteristic information of one or more cells recorded by the terminal may be referred to as the terminal history.

The terminal may retrieve its locally stored history before performing step 600.

In some embodiments, the history record records a cell identifier of at least one history registered cell and a corresponding history frequency point.

In some embodiments, a history frequency band (band) corresponding to the history registered cell is also recorded in the history record.

In some embodiments, the history also records the bandwidth of the history registered cell.

In some embodiments, the format of the history record may be as shown in Table 1.

TABLE 1

History registration cell 1	Cell identity 1	Historical frequency point 1	Historical frequency band 1	Bandwidth 1
					History registration cell 2	Cell identity 2	Historical frequency point 2	Historical frequency band 2	Bandwidth 2
History registration cell 3	Cell identity 3	Historical frequency point 3	Historical frequency band 3	Bandwidth 3

By scanning the history frequency points corresponding to the history registration cell, if the registrable cell is obtained, whether the history registration cell is a cell in the registrable cell can be judged according to the cell identification of the history registration cell.

In some embodiments, when there are two or more history registration cells, the terminal may scan history frequency points corresponding to all history registration cells first to obtain a registrable cell obtained by scanning all history frequency points. The registrable cell may refer to one cell, or may refer to two or more cells. The number of cells in the registrable cell is determined according to the scanning results of all the historical frequency points. Whether each of the history registered cells is included in the registerable cell can be judged according to the cell identification of each of the history registered cells.

In other embodiments, when there are two or more history registration cells, the terminal may scan sequentially for each history frequency point therein. When a registrable cell (the registrable cell may refer to one cell or two or more cells) is scanned, whether the cell corresponding to the cell identifier is the cell in the registrable cell may be determined according to the cell identifier corresponding to the currently scanned historical frequency point. If so, the terminal registers the cell corresponding to the cell identifier; if not, the terminal continues to scan the next historical frequency point until the cell corresponding to the cell identifier corresponding to the currently scanned historical frequency point is the cell in the registrable cell obtained by scanning the historical frequency point, or all the historical frequency points are scanned.

Step 602 may be performed when the registerable cells include at least one cell of the history registration cells.

Step 602, registering one cell of the at least one cell according to the bandwidth of the cell.

When the registrable cell includes one of the history registration cells, the cell is registered.

When the registrable cell includes two or more cells among the history registration cells, a cell with the largest bandwidth can be registered. Specifically, the priority ranking of the cells may be performed according to the order of the bandwidths of the two or more cells from large to small. Then, the cell with the highest priority is registered.

It is easy to understand that a cell in a frequency point corresponding to a primary cell of a secondary cell may be added to a terminal, or a secondary cell may be added to a terminal at a high probability. When the registrable cell obtained through the frequency points corresponding to the history registration cell does not include any cell in the history registration cells, step 604 may be executed, so that the terminal may register a cell in which a secondary cell may be added to the terminal at a high probability.

Step 604 registers one of the registrable cells based on the signal quality of the cell.

When there is only one cell among the registerable cells, the cell is registered.

When there are two or more cells in a registrable cell, the cells may be prioritized according to the signal quality of the registrable cell from high to low. Then, the cell with the highest priority is registered.

In some embodiments, signal quality specifically refers to signal strength. In one example, the signal strength may be characterized by a Reference Signal Receiving Power (RSRP).

In some embodiments, the signal quality may specifically be a Reference Signal Receiving Quality (RSRQ).

It is easy to understand that a cell in a frequency band corresponding to a primary cell of a secondary cell may be added to a terminal, or a secondary cell may be added to a terminal in a large probability. When no registrable cell is found by scanning the history frequency points corresponding to the history registration cells, step 606 is executed, so that the terminal registers cells, which can add secondary cells to the terminal, approximately.

Step 606, scanning a historical frequency band corresponding to the historical registered cell.

In some embodiments, when there are two or more history registration cells, the terminal may scan history frequency bands corresponding to all history registration cells first to obtain a registrable cell obtained by scanning all history frequency bands, where the registrable cell may refer to one cell or two or more cells. The number of cells in the registrable cell is determined specifically according to the scanning results of all historical frequency bands.

In other embodiments, when there are two or more history registration cells, the terminal may scan for each history frequency band in turn. When a registrable cell (the registrable cell may refer to one cell or two or more cells) is found by scanning one historical frequency band, the number of cells in the registrable cell is determined according to the scanning result of the currently scanned historical frequency band, and other unscanned historical frequency bands are not scanned any more.

By scanning the historical frequency band corresponding to the historical registered cell, if a registrable cell is obtained, step 608 is executed.

Step 608 registers one of the registrable cells according to the signal quality of the cell.

When no registrable cell is found by scanning the historical frequency band corresponding to the historical registration cell, steps 610 and 612 are performed.

And step 610, searching the network.

Step 612, registering the cell.

The specific implementation process of step 610 and step 612 may refer to the description of the prior art, and will not be described herein.

After the cells are successfully registered, i.e. camped on, through

steps

602, 604, 608, and 612, it is determined whether the currently camped cell can add a secondary cell to the terminal. Specifically, the terminal may know whether a random access procedure (see fig. 4) is completed between secondary network nodes corresponding to the camped cell of the terminal, and if so, the terminal may consider that the current camped cell may add a secondary cell to the terminal.

When the current resident cell can add a secondary cell to the terminal, the terminal can execute step 614, and can record the cell identifier, the frequency point, the frequency band and the bandwidth of the current resident cell to update the history.

The cell registration method provided by the embodiment of the application can enable the terminal to judge whether a main cell capable of adding an auxiliary cell for the terminal can be registered or not when the terminal is attached to the cell, and register the main cell if the main cell can be registered, thereby realizing the preferential registration of the main cell capable of adding the auxiliary cell for the terminal; especially, when the main cell is a 4G cell and the auxiliary cell is a 5G cell, the uplink and downlink throughput rate can be improved, and the experience of high rate is brought to the user.

The embodiment of the application provides a cell registration method, and an execution main body of the cell registration method is a terminal supporting double connection capacity. Referring to fig. 7, after the terminal has camped on a cell, that is, after the terminal performs step 700 and registers a cell, the terminal may know whether the currently camped cell may add a secondary cell to the cell. In some embodiments, the dual connectivity capability supported by the terminal is an EN-DC capability, the cell currently camped on may be a 4G cell, and the secondary cell is a 5G cell.

If the current camped cell cannot add a secondary cell to the terminal, the terminal may perform step 702.

Step 702, in an idle (idle) state, scanning the frequency point in the neighbor cell information.

And the neighbor cell information is configured by the base station corresponding to the current resident cell and is sent to the terminal. The neighboring cell information includes the frequency point configured by the base station.

The terminal may obtain a history record locally stored therein, where the history record includes characteristic information of a history registration cell, and the characteristic information may include a cell identifier, a history frequency point, and a history frequency band. For the history record, the history registered cell, and the feature information, reference may be made to the above description of the embodiment shown in fig. 6, and details are not repeated here.

When the registrable cell is found by scanning the frequency points in the neighbor cell information, whether the history registration cell is a cell in the registrable cell can be judged according to the cell identification of the history registration cell.

In some embodiments, when the number of frequency points in the neighbor information is two or more, the terminal may scan all frequency points in the neighbor information first to obtain a registrable cell. The registrable cell may refer to one cell, or may refer to two or more cells. The number of cells in the registrable cell is determined according to the scanning results of all frequency points in the neighbor information. Whether each history registration cell is included in the registerable cell can be judged according to the cell identification of each history registration cell.

In other embodiments, when the frequency points in the neighbor information are two or more, the terminal may scan sequentially for each of the frequency points. When a registrable cell (the registrable cell may refer to one cell or two or more cells, where the number of cells in the registrable cell is determined according to the scanning result of the currently scanned frequency point) is scanned, whether each cell is a cell in the registrable cell can be determined according to the cell identifier of the history registrable cell. If so, the terminal registers the cell corresponding to the cell identifier; if not, the terminal continues to scan the next frequency point in the neighbor information until the registrable cell obtained from the currently scanned frequency point comprises at least one cell in the history registration cells, or all frequency points in the neighbor information are scanned.

Step 704 may be performed when the registrable cell comprises at least one cell of the history registration cells.

Step 704, registering one cell of the at least one cell according to the bandwidth of the cell to switch the cell.

When the registrable cell includes two or more cells among the history registration cells, a cell with the largest bandwidth can be registered. Specifically, the priority ranking may be performed on the cells according to the order of bandwidths of the two or more cells from large to small. Then, the cell with the highest priority is registered.

When the registrable cell does not include any cell in the history registration cells, or no registrable cell is found by scanning frequency points in the neighboring cell information, step 706 may be executed.

Step 706, scanning the historical frequency points corresponding to the historical registered cells.

Step 706 may refer to the above description of step 600 in fig. 6, and will not be described herein again.

Step 708 may be performed when the registered cells obtained through step 706 include at least one of the historically registered cells.

Step 708, registering one cell of the at least one cell according to the bandwidth of the cell to switch the cell.

Step 708 may refer to the description of step 602 in fig. 6, and will not be described herein.

Step 710 may be performed when the registrable cell obtained in step 706 does not include a history registration cell and the registrable cell includes two or more cells.

Step 710, registering one of the registrable cells according to the signal quality of the cell to switch the cell.

Step 710 can refer to the above description of step 604 in fig. 6, and will not be described herein again.

Step 712 may be performed when there are no phenomena registrable cells via step 706.

And 712, scanning the historical frequency band corresponding to the historical registered cell.

Step 712 can refer to the above description of step 606 and will not be described herein.

When a registrable cell is obtained via step 712, step 714 may be performed.

Step 714 registers one of the registerable cells according to the signal quality of the cell to switch the cell.

Step 714 may be referred to above as step 608, and will not be described herein.

In some embodiments, when no registrable cell is found in step 712 and a registrable cell is obtained in step 702, the registrable cell does not include any cell of the history registration cells, one of the registrable cells obtained in step 702 may be registered to handover the cell.

In some embodiments, when no registrable cell is found through step 712, a network search, a cell handover may be performed.

After the cells are switched through the steps, whether the switched cells can add the auxiliary cells for the terminal or not can be judged. When the cell to which the terminal is handed over can add a secondary cell to the terminal, the terminal may perform step 716, and record the cell identifier, frequency point, frequency band, and bandwidth to which the terminal is handed over, so as to update the history.

In some embodiments, when no registrable cell is found through step 712, the terminal may continue to camp on the current cell without performing cell handover.

The method for registering the cell provided by the embodiment of the application can be used for judging whether the main cell capable of adding the auxiliary cell for the terminal can be registered or not when the terminal performs cell switching, and switching to the main cell if the main cell can be registered, so that the main cell capable of adding the auxiliary cell for the terminal is preferentially registered; especially, when the primary cell is a 4G cell and the secondary cell is a 5G cell, the uplink and downlink throughput rate can be improved, and high-rate experience is brought to users.

The embodiment of the application provides a cell registration method which can be applied to a terminal supporting double connection capacity. Referring to fig. 8, the method includes the following.

In a connected state where the terminal resides in a cell corresponding to the base station, the base station may send a measurement request to the terminal. The measurement request includes characteristic information of the measurement cell. The cell in which the terminal currently resides may be a cell in which an auxiliary cell can be added to the terminal, or a cell in which an auxiliary cell cannot be added to the terminal.

In some embodiments, the dual connection capability supported by the terminal may specifically be an EN-DC capability. The base station may be an eNB, and more particularly, the base station may be an MeNB.

After receiving the measurement request, the terminal may determine whether the history registered cell belongs to the measurement cell according to the characteristic information of the history registered cell.

For the history registration cell, reference may be made to the above description of the embodiment shown in fig. 6, and details are not described here.

The measurement cell may be at least one cell, and the history registration cell may also be at least one cell. The terminal can judge whether each cell belongs to the measurement cell according to the characteristic information of the history registration cell. The measurement cell may include a cell corresponding to the base station, and may also include cells corresponding to base stations around the base station.

In some embodiments, the measured cell and the history registration cell characteristic information may include a cell identification. The terminal judges whether the cell identification of the first cell in the history registration cell is consistent with the cell identification of the cell in the measurement cell, and if so, whether the first cell belongs to the measurement cell.

In some embodiments, the measured cell and the history registered cell feature information may include frequency points (frequency points corresponding to the history registered cells, which may be referred to as history frequency points). The terminal judges whether the frequency point corresponding to the first cell in the history registration cell is consistent with the frequency point corresponding to the cell in the measurement cell, and if so, the first cell belongs to the measurement cell.

In some embodiments, the measured cell and the history cell characteristic information may include a frequency band (a frequency band corresponding to the history cell may be referred to as a history frequency band). The terminal judges whether the frequency band corresponding to the first cell in the history registration cell is consistent with the frequency band corresponding to the cell in the measurement cell, and if so, whether the first cell belongs to the measurement cell.

When the first cell belongs to the measurement cell, the terminal measures a first signal quality of the first cell. It should be noted that, the terminal does not perform measurement on cells that do not belong to the history registration cell among the measurement cells.

In some embodiments, signal quality specifically refers to signal strength. In one example, signal strength may be characterized by RSRP.

In some embodiments, the signal quality may specifically be RSRQ.

And when the first signal quality meets the reporting threshold, the terminal sends the first signal quality to the base station. The reporting threshold is a threshold configured for the terminal by the base station.

And after receiving the first signal quality, the base station judges whether the first signal quality meets a cell switching threshold. The cell switching threshold is a threshold configured for the terminal by the base station.

And when the first signal quality meets the cell switching threshold, the base station sends a cell switching instruction to the terminal.

And the terminal is switched to the first cell according to the cell switching indication.

It is to be readily understood that the first cell may be two or more cells, and the terminal may measure respective first signal qualities of the two or more cells. When the first signal quality of any one of the two or more cells meets the reporting threshold, reporting the first signal quality of the cell to the base station, when the first signal quality of the cell meets the switching threshold, the base station sends a cell switching instruction to the terminal, and the terminal is switched to the cell according to the cell switching instruction.

In the cell registration method provided by the embodiment of the application, after receiving the measurement request, the terminal only measures and reports the signal quality of the main cell capable of adding the auxiliary cell to the terminal, so that all cell switching instructions received from the base station are used for switching to the main cell capable of adding the auxiliary cell to the terminal; especially, when the main cell is a 4G cell and the auxiliary cell is a 5G cell, the uplink and downlink throughput rate can be improved, and the experience of high rate is brought to the user.
