Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first client may be referred to as a second client, and similarly, a second client may be referred to as a first client, without departing from the scope of the present application. Both the first client and the second client are clients, but they are not the same client.
For a wireless communication terminal device, with an increase of a 5G coverage area, a terminal may generate a switching operation of a Dual Connectivity Cell (SCG) based on a 4G Dual Connectivity state (EUTRA-NR Dual Connectivity, endec) where the terminal is located, for example, the terminal has a scenario of switching from a Time Division Duplex (TDD) to a Frequency Division Duplex (FDD) frequency band. When the terminal can be switched to the FDD frequency band, the base station initiates the switching of the FDD frequency band to the terminal, firstly, the base station sends a configuration parameter releasing instruction to the terminal, and after receiving a terminal response, the configuration parameter is sent to the terminal according to a protocol specification, so that the terminal triggers bottom access according to the configuration parameter, and the SCG cell switching of the terminal is completed.
In the process of configuring the parameters, for the existing network coverage of LTE and NR, according to the current 38.331 protocol, only part of the configuration parameters in the protocol belong to modifiable parameters, that is, when performing cell handover, the base station only has the right to modify part of the configuration parameters in the terminal. For example, the base station configures the SRS with the signal parameter 1t4R in the N78 frequency band, but when the network switches to the N1 frequency band, only the codebook of the SRS is configured, and the signal parameter tx switch of the SRS is not configured. But the terminal may consider that the signal parameter tx switch of the SRS is configured by default in N1, thereby causing a configuration error. To solve this problem, the present solution provides a cell switching method, which is specifically described by the following embodiments.
Fig. 1 is a schematic diagram of an application environment of a cell handover method in an embodiment. As shown in fig. 1, fig. 1 shows a schematic structural diagram of a cell switching system, where the cell switching system includes a terminal 101 and a base station 102, and the terminal 101 may communicate with the base station 102 through a network protocol to implement a dual-cell switching function of the terminal. It should be noted that, for the existing LTE and NR network coverage, due to the difference of deployment environments, an operator follows a protocol for the current network parameter configuration but has respective characteristics, and the environment discussed in this embodiment is that, when both the base station and the terminal are in a dual connection scenario of LTE + TDD NR, and the terminal is in a situation that a FDD NR cell network configuration signal is good enough, the base station sends an instruction for switching a TDD NR cell to the terminal, so that the cell switching of the terminal is implemented based on the cell switching method provided in this embodiment.
Fig. 2 is a flow chart of a cell handover method in an embodiment. The cell switching method in this embodiment is described by taking the terminal operating in fig. 1 as an example. As shown in fig. 2, the cell switching method includes steps 201 to 203.
Step 201, receiving a cell switching instruction issued by a base station; the cell switching instruction carries configuration information of a target frequency band.
The target frequency band refers to a frequency band to which the terminal needs to be switched, for example, in a scenario of a dual-connection cell, a current frequency band of the terminal may be a time division duplex (TDD NR) frequency band, and then the target frequency band may be a Frequency Division Duplex (FDD) NR frequency band; the configuration information is protocol parameter information corresponding to each frequency band.
In this embodiment, the terminal receives a cell switching instruction issued by the base station, and optionally, the terminal may obtain a target frequency band and configuration information of the target frequency band carried by the terminal from the cell switching instruction based on a preset resolution protocol. Optionally, the cell switching instruction issued by the base station may be an instruction issued by the base station after determining that the network quality of the terminal meets a certain condition. This embodiment is not limited to this.
Step 202, if the target frequency band is not matched with the current frequency band, replacing the configuration information of the current frequency band with the configuration information of the target frequency band.
Whether the target frequency band is matched with the current frequency band can be determined in various forms. For example, the terminal may determine whether the target frequency band is matched with the current frequency band through the frequency band identifier of the target frequency band and the frequency band identifier of the current frequency band; or, the terminal may determine whether the target frequency band is matched with the current frequency band according to the configuration parameter of the target frequency band and the configuration parameter of the current frequency band.
In this embodiment, the terminal determines, by using any one of the above matching methods, that the target frequency band is not matched with the current frequency band, for example, if the frequency band identifier of the target frequency band is not consistent with the frequency band identifier of the current frequency band, or if the configuration parameter of the target frequency band is not consistent with the configuration parameter of the current frequency band, the configuration parameter corresponding to the frequency band needs to be modified, at this time, the terminal may obtain the configuration information of the target frequency band, and replace the configuration information of the current frequency band with the configuration information of the target frequency band, that is, empty the configuration information of the current frequency band, and use the configuration information of the target frequency band, which is not limited in this embodiment.
Step 203, performing cell switching according to the configuration information of the target frequency band.
In this embodiment, after determining that the target frequency band is not matched with the current frequency band, the terminal replaces the configuration information of the current frequency band with the configuration information of the target frequency band, that is, updates the configuration information to the configuration information of the target frequency band, thereby implementing frequency band switching, that is, operation of cell switching.
In the cell switching method in this embodiment, a terminal receives a cell switching instruction issued by a base station, replaces configuration information of a current frequency band with configuration information of the target frequency band when the target frequency band is not matched with the current frequency band according to configuration information of the target frequency band carried in the cell switching instruction, and performs cell switching according to the configuration information of the target frequency band. In the scheme, the terminal can directly replace the configuration information of the current frequency band by using the configuration information of the target frequency band based on the configuration information of the target frequency band in the cell switching instruction issued by the base station under the condition that the target frequency band is not matched with the current frequency band, so that the condition that the logic processing of the network configuration of the base station is not consistent with the logic processing of the parameter configuration of the terminal due to the modification of partial parameters of the current frequency band is avoided, and the stability of the cell switching of the terminal is improved.
In another case, in an alternative embodiment, if the target frequency band matches the current frequency band, the cell switching instruction is not responded.
In this embodiment, the terminal determines, through any one of the matching methods in step 202, that the target frequency band is matched with the current frequency band, that is, the frequency band identifier of the target frequency band is consistent with the frequency band identifier of the current frequency band, or the configuration parameter of the target frequency band is consistent with the configuration parameter of the current frequency band, which indicates that the terminal has accessed the target frequency band and does not need to perform cell handover, and at this time, the terminal does not respond to the cell handover instruction.
In this embodiment, under the condition that it is determined that the target frequency band is matched with the current frequency band, the terminal does not respond to the cell switching instruction issued by the base station, and the current configuration information is still kept unchanged, thereby avoiding the problem of inconsistent processing logics of the configuration parameters of the base station and the terminal caused by the modified configuration parameters of the terminal part.
Further, after the terminal acquires the target frequency band, the terminal may perform an operation of matching the target frequency band and the current frequency band according to the current frequency band. In one optional embodiment, as shown in fig. 3, the cell switching instruction further carries a frequency band identifier of the target frequency band, and the method further includes:
step 301, judging whether the target frequency band is matched with the current frequency band according to the frequency band identifier of the target frequency band and the frequency band identifier of the current frequency band, and obtaining a matching result.
The frequency band identifier may include information such as a frequency band number, a frequency band type, and a frequency band attribute corresponding to the frequency band.
In this embodiment, optionally, the terminal may determine whether the target frequency band is matched with the current frequency band according to the frequency band number of the target frequency band and the frequency band number of the current frequency band; or, the terminal may determine whether the target frequency band is matched with the current frequency band according to the frequency band type of the target frequency band and the frequency band type of the current frequency band; or, the terminal may determine whether the target frequency band is matched with the current frequency band according to the frequency band attribute of the target frequency band and the frequency band attribute of the current frequency band; or, the terminal may determine whether the target frequency band is matched with the current frequency band according to the configuration parameter of the target frequency band and the configuration parameter of the current frequency band, so as to obtain a matching result.
Step 302, if it is determined that the target frequency band is not matched with the current frequency band according to the matching result, replacing the configuration information of the current frequency band with the configuration information of the target frequency band.
In this embodiment, as described in the above example in step 301, if the frequency band number of the target frequency band is not consistent with the frequency band number of the current frequency band, the terminal determines that the target frequency band is not matched with the current frequency band; if the frequency band type of the target frequency band is not consistent with the frequency band type of the current frequency band, the terminal determines that the target frequency band is not matched with the current frequency band; if the frequency band attribute of the target frequency band is inconsistent with the frequency band attribute of the current frequency band, the terminal determines that the target frequency band is not matched with the current frequency band; and if the configuration parameters of the target frequency band are not consistent with the configuration parameters of the current frequency band, the terminal determines that the target frequency band is not matched with the current frequency band. In a case that the matching result is determined to be unmatched, the terminal may use the configuration information of the target frequency band by deleting the configuration information of the current frequency band, which is not limited in this embodiment.
In this embodiment, when the target frequency band is not matched with the current frequency band, the configuration information of the target frequency band is replaced with the configuration information of the current frequency band, so that the situation that the logic processing of the base station network configuration is not consistent with the logic processing of the terminal parameter configuration is avoided, and the stability of the terminal cell switching is improved. And whether the target frequency band is matched with the current frequency band can be determined according to the frequency band identification of the target frequency band and the frequency band identification of the current frequency band, and the judgment logic is simple and easy to realize.
The frequency band identifier may include multiple information, and different frequency band identifiers may use different determination logics, in one of the optional embodiments, if the frequency band identifier of the target frequency band includes a frequency band type of the target frequency band, and the frequency band identifier of the current frequency band includes a frequency band type of the current frequency band, then according to the frequency band identifier of the target frequency band and the frequency band identifier of the current frequency band, it is determined whether the target frequency band is matched with the current frequency band, including:
if the frequency band type of the target frequency band is consistent with the frequency band type of the current frequency band, determining that the target frequency band is matched with the current frequency band; and if the frequency band type of the target frequency band is not consistent with the frequency band type of the current frequency band, determining that the target frequency band is not matched with the current frequency band.
In this embodiment, exemplarily, if the frequency band type of the target frequency band is FDD NR and the frequency band type of the current frequency band is TDD NR, in this case, the terminal determines that the frequency band type of the target frequency band is not consistent with the frequency band type of the current frequency band, that is, determines that the target frequency band is not matched with the current frequency band; if the frequency band type of the target frequency band is FDD NR and the frequency band type of the current frequency band is FDD NR, in this case, the terminal determines that the frequency band type of the target frequency band is consistent with the frequency band type of the current frequency band, that is, determines that the target frequency band is matched with the current frequency band, which is not limited in this embodiment.
In this embodiment, the terminal may directly determine whether the current frequency band and the target frequency band are matched according to the frequency band type of the current frequency band and the frequency band type of the target frequency band, the process is simple, data processing resources are reduced, and the cell switching efficiency is improved.
In another optional embodiment, if the frequency band identifier of the target frequency band includes a frequency band type and a frequency band number of the target frequency band, the frequency band identifier of the current frequency band includes the frequency band type and the frequency band number of the current frequency band; judging whether the target frequency band is matched with the current frequency band according to the frequency band identifier of the target frequency band and the frequency band identifier of the current frequency band, wherein the judging step comprises the following steps:
if the frequency band number of the target frequency band is consistent with the frequency band number of the current frequency band, determining that the target frequency band is matched with the current frequency band; if the frequency band number of the target frequency band is inconsistent with the frequency band number of the current frequency band and the frequency band type of the target frequency band is consistent with the frequency band type of the current frequency band, determining that the target frequency band is matched with the current frequency band; and if the frequency band type of the target frequency band is not consistent with the frequency band type of the current frequency band, determining that the target frequency band is not matched with the current frequency band.
In this embodiment, for example, if the frequency band number of the target frequency band is N78, and the frequency band number of the current frequency band is N78, in this case, the terminal determines that the frequency band number of the target frequency band is consistent with the frequency band number of the current frequency band, that is, determines that the target frequency band matches with the current frequency band. If the frequency band number of the target frequency band is N78 and the frequency band number of the current frequency band is N79, in this case, the terminal determines that the frequency band number of the target frequency band is not consistent with the frequency band number of the current frequency band, in this case, the terminal may further determine whether the target frequency band is matched with the current frequency band according to the frequency band type of the target frequency band and the frequency band type of the current frequency band, where the frequency band type of the target frequency band is FDD NR and the frequency band type of the current frequency band is FDD NR, and in this case, the terminal determines that the frequency band type of the target frequency band is consistent with the frequency band type of the current frequency band, that is, the target frequency band is matched with the current frequency band. In addition, if the frequency band type of the target frequency band is FDD NR and the frequency band type of the current frequency band is TDD NR, in this case, the terminal determines that the frequency band type of the target frequency band is inconsistent with the frequency band type of the current frequency band, that is, determines that the target frequency band is not matched with the current frequency band, which is not limited in this embodiment.
In this embodiment, the terminal may determine whether the current frequency band is matched with the target frequency band according to the frequency band number and the frequency band type of the current frequency band, and the frequency band number and the frequency band type of the target frequency band, and perform frequency band matching operation based on two dimensions, thereby improving accuracy of frequency band matching and success rate of cell handover.
In order to make the information of the terminal and the base station symmetric, a global variable may be set to refer to the matching result, in an optional embodiment, the method further includes:
if the target frequency band is matched with the current frequency band, setting the value of the global variable in the matching result as a first value; and if the target frequency band is not matched with the current frequency band, setting the value of the global variable in the matching result as a second value.
For example, the global variable may be a boolean variable, for example, the terminal may set a boolean global variable freq _ type _ change to refer to a matching result, that is, record whether a frequency band type of the terminal changes based on the global variable.
In this embodiment, optionally, under the condition that it is determined that the target frequency band is matched with the current frequency band, setting a value of a global variable in the matching result to be a first value, for example, the first value may be "false" or "0", which indicates that the frequency band of the terminal is not changed, and the configuration parameter of the frequency band remains unchanged at present; under the condition that the target frequency band is determined not to be matched with the current frequency band, setting the value of the global variable in the matching result to be a second value, for example, the second value may be "true" or "1", which indicates that the frequency band of the terminal changes, and the current configuration parameter needs to be deleted, and the configuration parameter of the target frequency band is used.
Optionally, in an embodiment, the terminal sends a matching response message to the base station, where the matching response message includes the matching result. And the matching result comprises a global variable used for referring to the matching result.
In this embodiment, the terminal sends a matching response message including a global variable to the base station, where the terminal updates and replaces configuration information according to the received parameter configuration information of the target frequency band when the global variable is a second value, that is, the global variable is "true" or "1", and when the base station determines that the global variable is the second value, that is, the global variable frequency _ type _ change is "true" or "1", the base station does not need to initiate an air interface message to indicate to release the parameter configuration before the release, so that the interaction cost between the base station and the terminal is reduced.
In this embodiment, by setting the global variable to refer to the matching result, the terminal and the base station can simultaneously determine whether the terminal needs to switch the cell and whether the configuration parameter needs to be updated, so as to reduce interaction of air interface messages between the base station and the terminal, and to complete the switching action more quickly.
Fig. 4 is a flowchart of a cell handover method in an embodiment. The cell switching method in this embodiment is described by taking the base station operating in fig. 1 as an example. As shown in fig. 4, the cell switching method includes steps 401 to 402.
Step 401, sending a cell switching instruction to a terminal; the cell switching instruction carries configuration information of a target frequency band.
In this embodiment, optionally, the base station may send a network quality measurement instruction to the terminal in advance, receive a network quality measurement result returned by the terminal, and trigger the base station to issue a cell switching instruction to the terminal when the network quality measurement result of the terminal meets a quality condition, for example, the network quality measurement value of the terminal is greater than a quality threshold, where the cell switching instruction carries configuration information of a target frequency band and the target frequency band, and the target frequency band refers to a frequency band to which the terminal needs to be switched.
And the matching result comprises a global variable used for referring to the matching result. The base station may determine whether the current frequency band of the terminal changes according to the matching result or a global variable used for referring to the matching result, for example, if the base station determines that a value of the global variable in the matching result is a first value "false" or "0", it determines that the frequency band of the terminal does not change, and the configuration parameter of the frequency band remains unchanged at present; and if the base station determines that the value of the global variable in the matching result is the second value 'true' or '1', determining that the frequency band of the terminal changes, and using the configuration parameters of the target frequency band.
In the cell switching method, the base station sends the cell switching instruction to the terminal so that the terminal determines whether the current frequency band is matched according to the target frequency band in the cell switching instruction and the configuration information of the target frequency band, thereby receiving the matching response message which is sent by the terminal and carries the matching result. In the scheme, the base station issues the cell switching instruction to the terminal, so that the terminal can determine whether the configuration information of the current frequency band needs to be replaced again based on the configuration information of the target frequency band, the condition that the logic processing of the network configuration of the base station is inconsistent with the logic processing of the parameter configuration of the terminal is avoided, and the stability of the cell switching of the terminal is improved. Compared with the prior art, the method and the device have the advantages that the base station in the prior art is prevented from sending the instruction for releasing part of the configuration parameters to the terminal and then sending the specific content information of the configuration parameters, so that the terminal can perform multiple interactive operations of parameter configuration and cell switching.
To better explain the cell handover method, as shown in fig. 5, this embodiment describes a cell handover method from the perspective of interaction between a terminal and a base station, which specifically includes:
