Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to an information configuration method, an information configuration apparatus, a related device, and a storage medium.
Background
Inter-cell handover refers to the completion of the transition of radio link connection from a source cell to a target cell by a mobile terminal under the control of a radio access network, and is a basic technical means for ensuring seamless mobile communication service. Meanwhile, a handover mechanism in the related art is referred to as a normal handover or an immediate handover.
The handover mechanism is directly related to the service experience of the user in the wide area coverage network. In order to improve the experience of a user when the user moves at a high frequency or a high speed and reduce the handover failure rate, a mechanism of Conditional handover (expressed in english as Conditional handover Over, CHO) is proposed, as shown in fig. 1, that is, when the channel quality between User Equipment (UE) and a serving cell suddenly deteriorates (especially at a high frequency) and the UE cannot normally complete handover, a source base station may configure the UE to trigger measurement reporting at a lower threshold, and carry a higher handover triggering threshold in a Handover (HO) command, where the UE may also carry a random access resource used by the UE in a target cell, and once the handover threshold is satisfied, the UE initiates a random access process to the target base station.
However, in the CHO scheme, a large number of UEs simultaneously accessing to the same cell or the same beam may occur, thereby causing congestion.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
When the communication system introduces the beamforming (english may be expressed as beam) technology, in addition to the quality and parameter configuration at the cell (english may be expressed as cell) level, the quality and parameter configuration at the beam (english may be expressed as beam) level are also considered in the handover process.
In a conventional understanding handover process, a target base station may carry an available beam of a target cell and corresponding random access resources, such as an association relationship between a Preamble code (Preamble) and the beam, in a handover command according to information such as an actual load (load) and signal quality measured by a UE.
However, in the process of conditional handover, the network side cannot accurately determine the time and specific location of handover of the UE, and therefore may configure multiple beams and random access resources of the target cell for the UE in advance; if the UE selects the target cell and the target beam only based on the measured cell quality and beam quality, it may happen that a large number of UEs access the same cell or beam at the same time, resulting in congestion.
Based on this, in various embodiments of the present invention, the access probability and/or quality threshold for accessing the target cell and/or the target beam is configured for the terminal, so that each terminal can be dispersed to different cells and beams, and congestion is avoided.
The embodiment of the invention provides an information configuration method, which is applied to network equipment and comprises the following steps:
configuring threshold information for accessing a candidate target cell and/or accessing a candidate target beam when executing conditional switching for a terminal; the threshold information is used for judging whether a candidate target cell and/or a candidate target beam can be accessed when the terminal executes the condition switching; the threshold information includes at least one of the following information:
a signal quality threshold;
and (4) accessing a probability threshold.
In practical application, the network device may be a source base station, a target base station, or other network elements.
The network device determines the threshold information according to needs, for example, the threshold information may be preset for the network device, and the like, which is not limited in the embodiment of the present invention.
In practical application, the network device may configure the threshold information for the terminal through a Radio Resource Control (RRC) message (such as an RRC reconfiguration message).
In practical application, the threshold information of the candidate target cell for access when executing conditional handover configured for the terminal may be threshold information corresponding to each frequency point or each cell.
The threshold information for accessing the candidate target beams when performing the conditional handover configured for the terminal may be threshold information corresponding to each beam.
In one embodiment, the signal quality threshold comprises at least one of:
an RSRP threshold;
an RSRQ threshold;
and (4) an SINR threshold.
In practical applications, the threshold information may be for the SSB and/or the CSI-RS, that is, the terminal determines the signal quality and the access probability based on the SSB and/or the CSI-RS, so as to determine whether the candidate target cell and/or the candidate target beam can be accessed by using the signal quality threshold and the access probability threshold.
And the terminal judges whether the candidate target cell and/or the candidate target beam can be accessed or not according to the threshold information configured by the network side and the actually measured and generated random number.
Here, for the signal quality threshold, in practical application, when the signal quality measured by the terminal is equal to or higher than the signal quality threshold, the terminal can try to access the candidate target cell and/or access the candidate target beam. Of course, when the signal quality measured by the terminal is less than the signal quality threshold, the terminal cannot attempt to access the candidate target cell and/or access the candidate target beam.
The configured signal quality threshold may be in the form of a relative value or an absolute value. When the form of the threshold is a relative value, the configured signal quality threshold may be a relative value with respect to the signal quality of the current serving cell or the current serving beam.
For the access probability threshold, when the random number generated by the terminal is smaller than or equal to the access probability threshold in actual application, the terminal determines that the candidate target cell and/or the access candidate target beam can be used. Of course, when the random number generated by the terminal is less than or equal to the access probability threshold, the terminal determines that the candidate target cell and/or the access candidate target beam cannot be used.
In practical application, the signal quality threshold of the candidate target cell may be referred to as Tcellquality, the signal quality threshold of the candidate target beam may be referred to as tbeamplity, the access probability threshold of the candidate target cell may be referred to as Pcell, and the access probability threshold of the candidate target beam may be referred to as Pbeam.
Correspondingly, the embodiment of the invention also provides an information configuration method, which is applied to a terminal and comprises the following steps:
receiving threshold information of an access candidate target cell and/or an access candidate target beam when executing conditional switch configured by a network side; the threshold information is used for judging whether a candidate target cell and/or a candidate target beam can be accessed in the process of executing the condition switching by the terminal; the threshold information includes at least one of the following information:
a signal quality threshold;
and (4) accessing a probability threshold.
In practical application, when a network side configures the threshold information for the terminal through an RRC message, the terminal receives the threshold information through the RRC message.
When the threshold information of the access candidate target cell is the threshold information corresponding to each frequency point or each cell when the network side performs conditional switch configured for the terminal, the terminal receives the threshold information corresponding to each frequency point or each cell configured by the network side.
In an embodiment, when the threshold information of the access candidate target beam is the threshold information corresponding to each beam when the network side performs conditional handover configured for the terminal, the terminal receives the threshold information corresponding to each beam configured by the network side.
And in the process of executing the condition switching, the terminal judges whether the candidate target cell and/or the candidate target beam can be accessed or not by using the threshold information.
Specifically, in the process of executing the conditional switch, the terminal determines whether the candidate target cell and/or the candidate target beam corresponding to the threshold information can be accessed by using the parameters obtained by the terminal and combining the configured threshold information.
More specifically, for the signal quality threshold, in practical application, the terminal compares the measured signal quality with the signal quality threshold; the terminal can attempt to access the candidate target cell and/or access the candidate target beam only if the measured signal quality is equal to or higher than the signal quality threshold. Of course, when the signal quality measured by the terminal is less than the signal quality threshold, the terminal cannot attempt to access the candidate target cell and/or access the candidate target beam.
For the access probability threshold, in practical application, the terminal may generate a random number (i.e., access probability) between 0 and 1, and compare the generated random number with the configured access probability threshold; when the random number generated by the terminal is less than or equal to the access probability threshold, the terminal determines that the candidate target cell and/or the access candidate target beam can be used. Of course, when the random number generated by the terminal is less than or equal to the access probability threshold, the terminal determines that the candidate target cell and/or the access candidate target beam cannot be used.
Here, it should be noted that the method for generating the random number is not limited in the embodiment of the present invention.
In practical application, the timing for determining whether the terminal can use the candidate target cell and/or access the candidate target beam by using the access probability threshold may be after the terminal determines that other conditions are met (if configured by the network side), or may be before the determination of the other conditions.
In practical application, the other conditions may be configured as needed, for example, thresholds of beam and/or cell quality configured on the network side, such as thresholds of RSRP, RSRQ, or SINR, and the like. The embodiment of the present invention is not limited thereto.
For the access probability threshold, in practical application, the terminal may autonomously determine how to determine whether the candidate target cell and/or the candidate target beam can be used by using the access probability threshold for the candidate target cell and/or the candidate target beam.
The terminal may also be configured to determine whether the candidate target cell and/or the candidate target beam can be used by using an access probability threshold of the corresponding candidate target cell and/or the candidate target beam based on the signal quality of each candidate target cell and/or the candidate target beam; in this case, the terminal selects a candidate target cell and/or candidate target beam with high signal quality and meeting the requirement of the access probability threshold for access.
Certainly, in actual application, a situation that the access probability of each candidate cell and/or candidate beam does not satisfy the access probability threshold may occur, and at this time, the behavior of the terminal may be specified, for example, the candidate cell and/or candidate beam with the best signal quality is selected for handover, and then, for example, the candidate cell and/or candidate beam with the highest access probability configured on the network side is selected for handover, and the like.
An embodiment of the present invention provides an information configuration method, as shown in fig. 2, the method includes:
step 201: the network equipment configures threshold information for accessing a candidate target cell and/or accessing a candidate target beam when executing conditional switch for the terminal;
here, the threshold information is used for the terminal to determine whether the candidate target cell and/or the candidate target beam can be accessed when performing the conditional handover.
The threshold information includes at least one of the following information:
a signal quality threshold;
and (4) accessing a probability threshold.
