Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for configuring an alternative cell according to an embodiment of the present invention, and is applied to a network side device. As shown in fig. 1, the method comprises the following steps:
Specifically, the network side device may obtain the first information through at least one of the following manners: receiving capability reporting information sent by the terminal, wherein the capability reporting information comprises the first information; or acquiring the first information specified in a protocol; or acquiring the preset first information; or obtaining the first information from a core network.
That is to say, in the embodiment of the present invention, the network side device may obtain the first information according to the information reported by the terminal, may also obtain the first information of the terminal according to a predefined rule in a protocol, or may also obtain the first information according to a predefined agreement with the terminal, or may also obtain the first information from the core network. Through the methods, the network side equipment can flexibly acquire the first information.
If the capability report information sent by the terminal is received, in the embodiment of the present invention, the capability report information sent by the terminal through a Radio Resource Control (RRC) message may be received, where the RRC message includes a first identifier and a second identifier. The first identifier is used for indicating that the terminal supports conditional handover, and the second identifier is used for indicating the maximum value of the number of the candidate cells supported by the terminal.
And 102, under the condition that the terminal is determined to perform condition switching, determining alternative cells according to the first information, wherein the number of the alternative cells is less than or equal to the maximum value.
Specifically, in this embodiment, when it is determined that the terminal performs conditional handover, the network side device may send an admission request message to a plurality of target cells, receive configuration information sent by a target cell to be selected according to the admission request message, and then determine, according to the first information, a candidate cell from the target cell to be selected. The number of target cells for the network side device to send the admission request message may be any value. For example, it may be greater than the maximum value, or less than the maximum value, or may be equal to the maximum value.
The target cell to be selected refers to a target cell which can receive the terminal according to the receiving request message and sends configuration information of the terminal to the network side equipment.
For example, the source cell may send an admission request message to N target cells that may be handed over to the periphery according to the measurement result of the terminal. Wherein, N is a positive integer, and the value of N can be any value. For example, the value of N may be equal to the maximum value, or less than the maximum value, or greater than the maximum value.
And the target cell receiving the admission request message judges whether to admit the terminal according to the condition of the target cell. If so, the target cell prepares the corresponding radio resources and sends the corresponding configuration information to the source cell. Thus, the source cell may receive responses from multiple target cells. Thereafter, the source cell may select an alternative cell therefrom based on the first information. Wherein the number of the candidate cells is less than or equal to the maximum value.
When selecting the alternative cell, the network side device may select the alternative cell according to the signal quality, the service processing capability, and the like. For example, the cells may be ranked according to signal quality, and the cell with the highest ranked signal quality may be selected as the candidate cell.
And 103, sending the information of the alternative cell to the terminal.
In the embodiment of the invention, the network side equipment determines the alternative cells according to the maximum value of the number of the alternative cells supported by the terminal, thereby avoiding the problem of network side resource waste caused by excessive number of the alternative cells. Therefore, the embodiment of the invention can save network side resources.
Referring to fig. 2, fig. 2 is a flowchart of a method for configuring an alternative cell according to an embodiment of the present invention, and is applied to a terminal. As shown in fig. 2, the method comprises the following steps:
Specifically, in this step, the terminal may send capability reporting information to the network side device, where the capability reporting information includes the first information.
For example, the terminal may send capability reporting information to the network side device through an RRC message, where the RRC message includes a first identifier and a second identifier; the first identifier is used for indicating that the terminal supports conditional handover, and the second identifier is used for indicating the maximum value of the number of the candidate cells supported by the terminal.
In the embodiment of the invention, the network side equipment determines the alternative cells according to the maximum value of the number of the alternative cells supported by the terminal, thereby avoiding the problem of network side resource waste caused by excessive number of the alternative cells. Therefore, the embodiment of the invention can save network side resources.
Referring to fig. 3, fig. 3 is a flowchart of a method for configuring an alternative cell according to an embodiment of the present invention. In this embodiment, when reporting the terminal capability, the terminal reports the capability according to the number of the candidate cells under the condition supported by the terminal. The base station side stores the corresponding capabilities. When the terminal needs to be configured with the alternative cell, the base station performs configuration according to the capability reported by the terminal. The number of the alternative cells configured for the terminal by the base station does not exceed the number of the alternative cells supported by the terminal. For example, the terminal supports 3 candidate cells, the base station may configure 1 or 2 or 3 candidate cells for the UE.
As shown in fig. 3, the method includes:
and 301, when the terminal registers, reporting the capability, and reporting the capability information of the terminal to the network side equipment.
The capability information of the terminal comprises: and the maximum value of the number of the candidate cells which can be supported by the terminal during the condition switching. This capability information will be stored in the access network and the core network.
The capability information of the terminal can be reported to the network side device through an RRC message. The capability message of the terminal includes the following information, for example:
UEConditionHOCapabilityInformation-IEs::＝SEQUENCE{
conditionalHOFlag BOOLEAN,
maxNumCandidateCell INTEGER(1..12),OPTIONAL,--Cond concCHO
nonCriticalExtension SEQURENCE{}OPTIONAL
}
wherein, the conditional hoflag is used to identify whether the terminal supports conditional handover, TRUE indicates support, and FALSE indicates non-support. The maxNumCandidateCell is used to indicate the number of candidate cells supported by the terminal under the conditional handover, and may be, for example, the maximum value of the number of candidate cells supported. The identification of maxNumCandidateCell is present only when conditional hoflag is TRUE. The network side device can perform the alternative cell configuration on the terminal according to the value.
Step 302, when the terminal performs normal service, if the measurement reporting threshold is triggered, the measurement of the surrounding cells is performed according to the measurement configuration, and the measurement reporting is performed according to the reporting standard.
Step 303, the network side device determines the candidate cell.
And the network side equipment judges whether the terminal needs to carry out condition switching or not according to the measurement report message of the terminal. If necessary, the network side device prepares and configures the alternative cell according to the previously stored capability information of the terminal.
The capability information of the terminal may be obtained from the terminal or from the core network. When the information is obtained from the core network, the network side device interacts with the core network to obtain the information. The interaction mode between the network side device and the core network is not limited herein.
For example, the terminal supports at most 2 candidate cells, and then the network side prepares at most 2 candidate cells for the terminal to access under the condition switching.
Step 304, the network side device notifies the configured candidate cell to the terminal through an air interface message.
For example, the network side device may notify the terminal of the information of the alternative cell in an RRC connection reconfiguration message.
And 305, the terminal selects a proper alternative cell to access according to the trigger condition of the condition switching, and the switching is completed.
If the network-side device cannot obtain the maximum value of the number of candidate cells supported by the terminal in the above process, the network-side device may determine the candidate cells according to a default value, for example, the default value may be 2.
By using the scheme of the embodiment of the invention, under the condition of condition switching, the network side equipment does not configure the terminal with excessive prepared cells according to the maximum value of the number of the alternative cells supported by the terminal, thereby reducing the signaling overhead between the network side cells, reducing the air interface signaling overhead and saving the reserved cell resources. Meanwhile, the configured alternative cells consider the capability of the terminal, so that the terminal does not need to select an access cell from too many alternative cells, thereby reducing the power consumption of the terminal and improving the access efficiency.
