The handover procedure of the conditional handover includes a handover condition (also referred to as a handover trigger condition) in the handover command, compared to the conventional handover procedure, where the handover condition may be, for example, whether the signal quality of the candidate target cell is higher than the signal quality of the serving cell by a predetermined offset. After receiving the handover command, a User Equipment (UE) determines whether a handover Execution condition (Execution condition) is satisfied, and when the handover Execution condition is satisfied, the UE may access the target cell by using a configuration parameter of the candidate target cell included in the handover command, synchronize with the target cell, and initiate a random access procedure in the target cell, and when the handover Execution condition is not satisfied, the UE continues to maintain Radio Resource Control (RRC) connection with the source base station.

A Primary Secondary Cell (PSCell) is disposed on the Secondary base station side. The PSCell may also change with the change of the UE location, and when a conditional handover mechanism, i.e., a primary and secondary cell condition update, is introduced into the PSCell change, the source secondary base station or the primary base station may trigger the PSCell condition update.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
The embodiments of the present application are explained first with reference to terms of art:
conditional Handover (CHO): the handover command includes a handover condition (also referred to as a handover execution condition). The handover condition may be, for example, determining whether the signal quality of the candidate target cell is higher than that of the serving cell by a predetermined offset, after receiving the handover command, the UE determines whether the handover condition is satisfied, and when the handover condition is satisfied, the UE may access the target cell by using the configuration parameters of the candidate target cell included in the handover command, synchronize with the target cell, and initiate a random access procedure in the target cell, and when the handover condition is not satisfied, the UE continues to maintain Radio Resource Control (RRC) connection with the source base station. The source base station may configure a plurality of candidate target cells and corresponding handover execution conditions.
When the UE receives the CHO, the UE continues to maintain RRC connection with the source base station, during the period, the UE continues to execute measurement according to the measurement configuration configured by the source base station, reports the adjacent cell meeting the reporting condition, and the source base station can adjust the switching condition at any time according to the actual condition, or adjust the candidate target cell, or send the switching command of the unconditional switching. Therefore, the source base station needs to grasp the channel environment change where the UE is located in real time so as to make a decision in time, and avoid that the UE switches to an inappropriate neighboring cell, if the UE switches to a neighboring cell that is not the highest signal quality on a certain frequency, when the UE switches to a neighboring cell that is not the highest signal quality, uplink and downlink signal transmission of the UE is greatly interfered, the source base station may make a decision to switch again, and the switching process may affect the data transmission rate, thereby affecting the user experience.
Double connection: it means that the UE maintains a connection state with two base stations (one is a primary base station and one is a secondary base station), and can simultaneously receive signaling and data from the two base stations and transmit signaling and data to the two base stations.
According to protocol specifications, dual Connectivity (MR-DC) is of different types. Such as EN-DC, NE-DC, NR-DC, etc. For EN-DC, an LTE base station is a main base station, and a New Radio (NR) base station is an auxiliary base station; for NE-DC, an NR base station is a main base station, and an LTE base station is an auxiliary base station; for NR-DC, both the primary and secondary base stations are NR base stations. Expecting to establish the UE of the dual connection to establish RRC connection with the main base station at first, receive system message, paging command from the main base station, then dispose the auxiliary base station for UE by the main base station; the secondary base station may configure a Signaling Radio Bearer (SRB) so that the secondary base station performs direct RRC signaling interaction with the UE, where the SRB is mainly used for transmitting a radio parameter configured by the secondary base station and an uplink transmission measurement report of the UE.
It should be noted that, the main base station side is configured with a main cell, and the main cell is governed by the main base station; the auxiliary base station side is configured with a primary and secondary cell PSCell, the primary and secondary cells are governed by the auxiliary base station, the primary and secondary base station sides can be configured with other secondary cells, the number of the secondary cells can be 0, 1, 2, 3, etc., and the specific data depends on the capability of the UE.
Usually, as the location of the UE changes, the primary and secondary cells also change, and the source secondary base station or the primary base station determines to adopt the primary and secondary cell condition update, however, in the prior art, how to process the update of the PSCell when the source secondary base station or the primary base station determines to adopt the primary and secondary cell condition update is not considered, and when the radio parameters configured for the UE by the candidate secondary base station are different from the radio parameters configured for the UE by the source secondary base station, the master and secondary base stations update the PSCell.
In order to solve the problem, an embodiment of the present application provides a method for processing primary and secondary cell update, in a process of updating conditions of a primary and secondary cell, taking a radio parameter configured for a UE by a candidate secondary base station as a consideration factor, and synchronizing the radio parameter configured for the UE by the candidate secondary base station to a primary base station, thereby implementing update of the primary and secondary cell.
Fig. 1 is an application scenario schematic diagram of a method for processing primary and secondary cell update provided in an embodiment of the present application, and as shown in fig. 1, the method for processing primary and secondary cell update provided in this embodiment may be applied to a 5G communication system or a future communication system, where the 5G communication system relates to a first base station (i.e., a candidate secondary base station), a second base station (i.e., a primary base station), a third base station (i.e., a source secondary base station), and a user equipment UE, where the primary base station and the source secondary base station are base stations to which the UE currently accesses, and a primary and secondary cell is configured on a side of the source secondary base station.
It should be noted that the number of candidate secondary base stations shown in fig. 1 is 1, and in practical applications, the number of candidate secondary base stations includes, but is not limited to, one.
A UE may be a wireless terminal that may refer to a device providing voice and/or other traffic data connectivity to a user, a handheld device having wireless connection functionality, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or called a "cellular" telephone) and a computer having a mobile terminal, e.g., a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For example, personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Device or User Equipment (User Equipment), which are not limited herein.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a first interaction flowchart of a method for processing primary and secondary cell update provided in the embodiment of the present application, and as shown in fig. 2, the method for processing primary and secondary cell update provided in the embodiment includes:
s101, the second base station sends the acquired condition updating request of the primary cell and the secondary cell to the first base station.
In the embodiment of the application, the first base station, the second base station, and the third base station are respectively a candidate auxiliary base station, a main base station, and a source auxiliary base station.
The primary and secondary cell condition updating request includes a first radio parameter configured for the UE by the third base station, that is, the UE currently uses the radio parameter configured by the source secondary base station. The signal quality of the cell administered by the first base station meets a preset condition, that is, the candidate primary and secondary cells generally meet the preset condition, where the preset condition may be a preset offset of the signal quality of the cell administered by the first base station compared with the signal quality of the cell administered by the source secondary base station.
In practical application, the primary base station may obtain the primary and secondary cell condition update request in two ways:
firstly, a condition updating request of a primary cell and a secondary cell is obtained through a third base station.
When the UE is in dual connectivity, the UE can execute measurement according to a measurement task configured by a source-auxiliary base station and report a measurement report to the source-auxiliary base station, wherein the measurement report comprises an identifier and signal quality of a serving cell meeting a reporting condition, the source-auxiliary base station can determine to execute condition updating of a primary cell and an auxiliary cell according to the measurement report, the source-auxiliary base station determines a candidate primary cell and an auxiliary cell according to the signal quality of the cell reported by the UE, a base station to which the candidate primary cell and the auxiliary cell belong is determined as a candidate auxiliary base station, a primary cell and auxiliary cell condition updating request is sent to the primary base station, and the primary base station receives and sends the primary cell and auxiliary cell condition updating request to the candidate auxiliary base station. The reporting condition may be determined according to an actual situation, which is not limited in this embodiment.
Accordingly, the candidate secondary base station receives a primary-secondary cell condition update request from the primary base station.
And secondly, when the UE is in dual connectivity, the UE can execute measurement according to a measurement task configured by the main base station and report a measurement report to the main base station, wherein the measurement report comprises the identification and the signal quality of a service cell meeting the reporting condition, the main base station can determine to execute the condition updating of the main cell and the auxiliary cell according to the measurement report, the main base station determines a candidate main cell and an auxiliary cell according to the signal quality of the cell reported by the UE, determines a base station to which the candidate main cell and the auxiliary cell belong as a candidate auxiliary base station, and sends a main cell and auxiliary cell condition updating request to the candidate auxiliary base station. The reporting condition may be determined according to an actual situation, which is not limited in this embodiment.
Accordingly, the candidate secondary base station receives a primary-secondary cell condition update request from the primary base station.
It should be noted that the number of candidate primary and secondary cells includes, but is not limited to, one, and the number of candidate secondary base stations includes, but is not limited to, one.
S102, the first base station responds to the condition updating request of the primary and secondary cells and allocates wireless resources for the UE.
S103, the first base station sends a request confirmation message to the second base station.
The request acknowledgement message includes a radio resource and indication information, and the indication information is used to indicate whether a second radio parameter corresponding to the radio resource is the same as the first radio parameter.
After receiving the condition update request of the primary and secondary cells under the condition of resource permission, the candidate secondary base station responds to the condition update request of the primary and secondary cells, allocates wireless resources such as random access resources for the UE, and sends a request confirmation message to the primary base station, wherein the request confirmation message is used for indicating that the candidate secondary base station successfully receives the condition update request of the primary and secondary cells.
If the second wireless parameters are the same as the first wireless parameters, the request confirmation message comprises indication information indicating that the second wireless parameters are the same as the first wireless parameters; and if the second wireless parameters are different from the first wireless parameters, the request confirmation message comprises indication information indicating that the second wireless parameters are different from the first wireless parameters.
Wherein the first radio parameters and the second radio parameters each include a bandwidth combination (Band combination) and a feature set (feature set). The bandwidth combination represents a combination of a plurality of bandwidth combinations, and the characteristic set represents a set of characteristic parameters of the UE on each bandwidth. Determining that the first wireless parameter and the second wireless parameter are different when the bandwidth combination and/or the set of characteristics in the first wireless parameter and the second wireless parameter are different.
When the candidate auxiliary base station allocates the wireless resource to the UE, it is necessary to configure a wireless parameter, i.e. a second wireless parameter, for the UE, in order to avoid that the main base station analyzes the wireless resource carried by the request acknowledgement message to obtain the second wireless parameter when receiving the request acknowledgement message, where the request acknowledgement message includes the wireless resource and indication information indicating whether the second wireless parameter corresponding to the wireless resource is the same as the first wireless parameter. In this way, when the main base station receives the request confirmation message sent by the candidate secondary base station and the request confirmation message includes the indication information indicating that the second wireless parameter is the same as the first wireless parameter, the main base station does not need to analyze the second wireless parameter corresponding to the wireless resource, and the working efficiency of the main base station is improved. When the request confirmation message comprises indication information indicating that the second wireless parameter is different from the first wireless parameter, the main base station can immediately determine whether to directly send the condition updating message of the main and auxiliary cells to the UE without analyzing the wireless resource, so that the processing speed is improved, meanwhile, the main base station can store the second wireless parameter, and the second wireless parameter is analyzed when the UE accesses the auxiliary base station to which the second wireless parameter belongs.
The reason why the second wireless parameter is synchronized to the master base station, that is, the second wireless parameter is analyzed when the UE accesses the secondary base station to which the second wireless parameter belongs, is as follows: in some service scenarios, the primary base station needs to perform configuration of other parameters according to wireless parameters configured for the UE by the secondary base station (if the UE may subsequently access the candidate secondary base station, the candidate secondary base station is the secondary base station).
In this embodiment, the candidate secondary base station sends the request acknowledgement message to the primary base station, and accordingly, the primary base station receives the request acknowledgement message from the candidate secondary base station.
And S104, responding to the request confirmation message, and sending a primary and secondary cell condition updating message to the UE by the second base station.
And after receiving the request confirmation message, the main base station responds to the request confirmation message and sends a main and auxiliary cell condition updating message to the UE, and the UE is used for executing the main and auxiliary cell condition updating. The primary and secondary cell condition updating request further includes an identifier of the candidate primary and secondary cell and an execution condition for updating the primary and secondary cell. The identifier of the primary and secondary cells may be frequency information and a physical cell identifier of the cell, and the execution condition for updating the primary and secondary cells may be that the signal quality of the cell governed by the first base station is higher than the signal quality of the cell governed by the source secondary base station by a preset offset. In this embodiment, the signal quality of the cell is the signal quality of the cell measured by the UE.
If the indication information indicates that the second wireless parameters are different from the first wireless parameters, the condition updating message of the primary and secondary cells comprises the identification of the candidate primary and secondary cells, the execution condition of the updating of the primary and secondary cells and wireless resources; and if the indication information indicates that the second wireless parameters are the same as the first wireless parameters, the condition updating message of the primary and secondary cells comprises the marks of the candidate secondary cells.
Wherein, if the indication information indicates that the second radio parameter is the same as the first radio parameter, sending a primary and secondary cell condition update message to the UE in response to the request acknowledgement message, including:
and sending the request confirmation message to a third base station, wherein the third base station is used for responding the request confirmation message and sending a primary and secondary cell condition updating message to the UE.
In the case that the second radio parameter is the same as the first radio parameter, the primary base station may send a request acknowledgement message to the source-secondary base station, and after receiving the request acknowledgement message, the source-secondary base station sends a primary-secondary cell condition update message to the UE in response to the request acknowledgement message.
Of course, if the execution condition for the primary and secondary cell update is set by the primary base station, the primary and secondary cell condition update message further includes the execution condition for the primary and secondary cell condition update.
Accordingly, the UE performs the primary and secondary cell condition update in response to the primary and secondary cell condition update message, and a specific process of performing the primary and secondary cell condition update by the UE is described in detail in a specific embodiment below.
The method for processing primary and secondary cell update provided by the embodiment includes: the second base station sends the acquired condition updating request of the primary and secondary cells to the first base station, the condition updating request of the primary and secondary cells comprises first wireless parameters configured by the third base station for User Equipment (UE), the first base station responds to the condition updating request of the primary and secondary cells and allocates wireless resources for the UE, the first base station sends a request confirmation message to the second base station, responds to the request confirmation message, the second base station sends the condition updating message of the primary and secondary cells to the UE, and the UE is used for executing the condition updating of the primary and secondary cells. In the process of updating the conditions of the main and auxiliary cells, the wireless parameters configured for the UE by the candidate auxiliary base station are taken as the consideration factors, and the wireless parameters configured for the UE by the candidate auxiliary base station are synchronized to the main base station, so that the updating of the main and auxiliary cells is realized.
The primary and secondary cell update procedure is described in an embodiment.
Fig. 3 is a first schematic diagram of a primary and secondary cell update process provided in this embodiment, and as shown in fig. 3, the primary and secondary cell update process provided in this embodiment includes the following steps:
step 1: the UE establishes dual connectivity.
And 2, step: and the UE executes measurement according to the measurement configuration, and reports a measurement report to the source secondary base station or the main base station when the reporting condition is met.
Specifically, the UE may perform measurement according to a measurement task configured by the main base station, and then report a measurement report to the main base station when there is a serving cell satisfying a reporting condition, where the measurement report includes an identifier and signal quality of the serving cell satisfying the reporting condition. Similarly, the UE may perform measurement according to the measurement task configured by the source secondary base station, and then report a measurement report to the source secondary base station when there is a serving cell satisfying a reporting condition.
And step 3: and the source secondary base station or the main base station decides to execute the condition updating of the main and secondary cells.
When the UE reports the measurement report to the source auxiliary base station, the source auxiliary base station determines to execute the condition updating of the primary and secondary cells; and when the UE reports the measurement report to the main base station, the main base station determines to execute the condition updating of the main and the auxiliary cells.
When the source secondary base station determines to execute the condition updating of the primary and secondary cells, executing the step 4; when the master base station determines to perform the master-slave cell condition update, step 4A is performed.
And 4, step 4: the source auxiliary base station selects one or more candidate main and auxiliary cells, and sends a main and auxiliary cell condition updating request to a base station, namely a candidate auxiliary base station, to which the candidate main and auxiliary cells belong through the main base station.
The primary and secondary cell condition update request includes radio parameters configured for the UE by the primary base station side, and particularly includes secondary base station configuration restriction information (configrictinfoscg) set by the primary base station, UE capability information, and radio parameters (sourceConfigSCG) configured for the UE by the source and secondary base stations, where the radio parameters configured for the UE by the source and secondary base stations are the first radio parameters in the embodiment in fig. 2.
The primary and secondary cell condition request further includes an execution condition (execution condition) for updating the primary and secondary cells and an identifier of the candidate primary and secondary cells, where the execution condition for updating may be that the signal quality of the candidate primary and secondary cells is higher than that of the source primary and secondary cells by a preset offset, and when the execution condition is met, the UE executes the updating of the primary and secondary cells.
It should be noted that the primary and secondary cell condition update request may adopt other names, such as a secondary base station condition update request. The UE in dual connectivity may configure carrier aggregation on the secondary base station side, so the primary and secondary cell condition update request is not limited to the update of the primary and secondary cells, but may also include the update of other secondary cells, that is, the candidate secondary base station may configure only the parameters of the candidate PSCell for the UE, or may configure the parameters of the candidate primary and secondary cells and the parameters of one or more secondary cells for the UE.
When the source secondary base station selects a plurality of candidate primary and secondary cells, the source secondary base station may send primary and secondary cell condition update requests to the plurality of candidate secondary base stations in parallel, or may send primary and secondary cell condition update requests to the plurality of candidate secondary base stations in advance.
Step 4A: the main base station selects one or more candidate main and auxiliary cells, and sends a main and auxiliary cell condition updating request to a base station to which the candidate main and auxiliary cells belong, namely a candidate auxiliary base station.
When the master base station selects a plurality of candidate master and slave base stations, master and slave cell condition updating requests can be sent to the candidate slave base stations in parallel, or the master and slave cell condition updating requests can be sent to the candidate slave base stations in advance.
And 5: after receiving the request for updating the conditions of the primary and secondary cells, the candidate secondary base station performs admission control according to the cell load and the like, and receives the request for updating the conditions of the primary and secondary cells under the condition of resource allowance.
The number of candidate secondary base stations may be plural, and for example, includes candidate secondary base station 1 and candidate secondary base station 2. The candidate secondary base stations dominate the candidate primary and secondary cells, the number of the candidate primary and secondary cells can be multiple, and the candidate secondary base stations can correspond to the candidate primary and secondary cells one to one or one to many.
Step 6: after receiving the request for updating the conditions of the primary and secondary cells, the candidate secondary base station allocates necessary radio resources, such as random access resources, to the UE, and sends a request acknowledgement message to the primary base station, where the request acknowledgement message includes SCG config, which is the radio resources configured by the candidate secondary base station for the UE.
When configuring necessary radio resources for the UE, the candidate secondary base station needs to configure radio parameters (i.e. second radio parameters) for the UE, and if the second radio parameters configured by the candidate secondary base station are different from the first radio parameters configured by the source secondary base station for the UE, the request acknowledgement message further includes indication information, that is, MNinvolved, for indicating that the first radio parameters are different from the second radio parameters, and at the same time, may include an execution condition for updating the conditions of the primary and secondary cells, because the primary and secondary cell condition update command is sent to the UE by the primary base station at this time, in order to avoid that the primary base station retrieves the condition update execution condition corresponding to the candidate primary and secondary cells, the candidate secondary base station may directly indicate the condition update execution condition in the request acknowledgement message; if the second radio parameter configured by the candidate secondary base station is the same as the first radio parameter configured by the source secondary base station for the UE, the request acknowledgement message further includes indication information, that is, MN not affected used to indicate that the first radio parameter is the same as the second radio parameter, or the request acknowledgement message does not indicate MN affected (or MN not affected), which also indicates that the first radio parameter is the same as the second radio parameter.
Wherein the first radio parameters and the second radio parameters each include a bandwidth combination (Band combination) and a feature set (feature set).
When the main base station receives the request confirmation message, if the message contains the indication of MN involved, the main base station saves the SCG config sent by the candidate secondary base station, and then step 7 is executed. If the message contains indication information of the MN not involed or does not include the MN involved, the primary base station forwards the request acknowledgement message to the source secondary base station, and then performs step 7A.
And 7: when a plurality of candidate primary and secondary cells exist, the primary base station sends a primary and secondary cell condition update message to the UE, and the primary base station may send the plurality of primary and secondary cell condition update messages at one time through Radio Resource Control (RRC) reconfiguration signaling, or may send the plurality of primary and secondary cell condition update messages in sequence by using a plurality of RRC reconfiguration signaling.
The primary and secondary cell condition updating message comprises the candidate primary and secondary cell identification, the execution condition of the primary and secondary cell updating, the second wireless resource configured by the candidate secondary base station for the UE, and the like. Different candidate primary and secondary cells may have different or the same updated execution conditions. The master base station may obtain the updated execution condition from the source secondary base station or obtain the updated execution condition when forwarding the condition update request in step 4 described above.
Step 7A: and the source auxiliary base station sends a signaling for updating the conditions of the main and auxiliary cells to the UE, and can send one or more information for updating the conditions of the main and auxiliary cells at one time through RRC reconfiguration signaling.
And step 8: and the UE receives the condition updating message of the primary and secondary cells and evaluates whether the candidate primary and secondary cells meet the execution condition of updating.
And step 9: and when at least one candidate main and auxiliary cell meets the updating execution condition, the UE selects one of the candidate main and auxiliary cells as a target main and auxiliary cell, or selects the candidate main and auxiliary cell with the best signal quality as the target main and auxiliary cell, or randomly selects one of the candidate main and auxiliary cells as the target main and auxiliary cell.
Step 10: and the UE sends the identification of the target main and auxiliary cells to the main base station, namely the target main and auxiliary cells to which the UE is about to access.
The UE can indicate the identification of the target main and auxiliary cells to be accessed to the main base station through RRC signaling, and after receiving the indication information, the main base station can forward (forward) the data of the data radio bearer established by the UE to the target auxiliary base station in advance, so that the UE can immediately receive downlink data sent by the target auxiliary base station after accessing the target auxiliary base station. The target secondary base station governs the target primary and secondary cells, for example, the target secondary base station is the candidate secondary base station 1.
Step 11: and the UE randomly accesses the target auxiliary base station.
Steps 10 and 11 may be performed in parallel. The first wireless parameters and the second wireless parameters are the same, namely the bandwidth combination and the characteristic set are the same, but other parameters except the bandwidth combination and the characteristic set configured for the UE by the candidate auxiliary base station can be different from the corresponding parameters configured for the UE by the source auxiliary base station, and the UE randomly accesses a target main and auxiliary cell governed by the target auxiliary base station through wireless resources corresponding to the second wireless parameters configured for the UE by the target auxiliary base station; and when the first wireless parameters and the second wireless parameters are different, namely the single-wide combination and/or the characteristic set are different, the UE randomly accesses a target main and auxiliary cell governed by the target auxiliary base station through wireless resources corresponding to the second wireless parameters configured for the UE by the target auxiliary base station.
Step 12: and after the UE is successfully accessed into the target auxiliary base station, the target auxiliary base station sends a main and auxiliary cell updating completion message to the main base station.
Step 13: the master base station informs the source secondary base station and other candidate secondary base stations, such as candidate secondary base station 1, to release the context of the UE.
Wherein, steps 8 to 13 are specific procedures for the UE to perform the primary and secondary cell update.
Further, the embodiment of the present application may also include another possible implementation, which is described below with reference to the embodiment of fig. 4.
Fig. 4 is a second schematic diagram of a primary and secondary cell update process provided in this embodiment, and as shown in fig. 4, the primary and secondary cell update process provided in this embodiment includes the following steps:
step 1: and the main base station sends the acquired condition updating request of the main and auxiliary cells to the candidate auxiliary base stations.
Step 2: and the candidate auxiliary base station responds to the condition updating request of the main and auxiliary cells and allocates wireless resources for the UE.
And step 3: the candidate secondary base station sends a request acknowledgement message to the primary base station.
The request acknowledgement message includes the radio resource and the execution condition of the primary and secondary cell update, the execution condition of the primary and secondary cell update is carried in the primary and secondary cell update request, and the primary and secondary cell update request further includes the identifier of the candidate primary and secondary cells.
It should be noted that the number of candidate secondary base stations may be multiple, and the candidate secondary base stations dominate the candidate primary and secondary cells, so that the number of candidate primary and secondary cells may also be multiple, and the candidate secondary base stations may correspond to the candidate primary and secondary cells one to one or one to many.
And 4, step 4: the primary base station transmits a request acknowledgement message to the UE.
After receiving the request confirmation message sent by the candidate secondary base station, the primary base station may send the request confirmation message to the UE through RRC signaling. Accordingly, the UE receives a request acknowledgement message from the primary base station.
Step 4 includes two cases:
firstly, a main base station sends a request confirmation message to UE;
and secondly, the main base station sends the request confirmation message to the source auxiliary base station, and the source auxiliary base station sends the request confirmation message to the UE.
The request acknowledgement message includes the radio resource and the execution condition of the primary and secondary cell update, the execution condition of the primary and secondary cell update is carried in the primary and secondary cell update request, and the primary and secondary cell update request further includes the identifier of the candidate primary and secondary cells.
And 5: the UE determines whether the second radio parameter corresponding to the radio resource is the same as the first radio parameter.
If yes, executing step 6; if not, executing step 7 or 7A.
And 6: and the UE determines a target main and auxiliary cell according to the candidate main and auxiliary cells and accesses the target auxiliary base station through a random access process.
Wherein the steps specifically include steps 8 to 13 in fig. 3. The first wireless parameters and the second wireless parameters are the same, namely the bandwidth combination and the characteristic set are the same, but other parameters except the bandwidth combination and the characteristic set configured for the UE by the candidate auxiliary base station can be different from the corresponding parameters configured for the UE by the source auxiliary base station, and the UE randomly accesses to the target main and auxiliary cells governed by the target auxiliary base station through the wireless resources corresponding to the second wireless parameters configured for the UE by the target auxiliary base station.
And 7: and the UE determines a target main and auxiliary cell according to the candidate main and auxiliary cells, sends the identification and the indication information of the target main and auxiliary cell to the main base station, and accesses the target auxiliary base station through a random access process.
The indication information is used for indicating whether the second wireless parameters are the same as the first wireless parameters.
In this way, when the main base station receives the indication information, if the indication information indicates that the second wireless parameter is different from the first wireless parameter, the main base station may analyze the wireless resource configured by the candidate auxiliary base station originally stored in step 2 to obtain the second wireless parameter; if the indication information indicates that the second radio parameter is the same as the first radio parameter, the target secondary base station can know that the same bandwidth combination and characteristic set are configured for the UE without analyzing the radio resource. Thus, the second wireless parameters can be synchronized to the main base station by the indication information.
The determining, by the UE, the target primary and secondary cells according to the candidate primary and secondary cells specifically includes steps 8 to 9 in fig. 3; accessing the target primary and secondary cells through the random access procedure specifically includes steps 11 to 13 in fig. 3.
Step 7A: and the UE determines a target main and auxiliary cell according to the candidate main and auxiliary cells, randomly accesses the target auxiliary base station, and sends the indication information to the main base station.
Wherein the steps specifically include steps 8 to 13 in fig. 3. When the first wireless parameters and the second wireless parameters are different, the UE randomly accesses a target main and auxiliary cell governed by the target auxiliary base station through wireless resources configured for the UE by the target auxiliary base station.
After the UE successfully accesses the target main and auxiliary cells, the target auxiliary base station sends indication information to the main base station, and if the indication information indicates that the second wireless parameters are different from the first wireless parameters, the main base station can analyze the wireless resources to obtain the second wireless parameters; if the indication information indicates that the second radio parameter is the same as the first radio parameter, the target secondary base station can be known to configure the same bandwidth combination and characteristic set for the UE without analyzing the radio resource. Therefore, the main base station can timely acquire the parameter configuration of the auxiliary base station side through the judgment of the target side; meanwhile, the main base station is prevented from analyzing wireless parameters configured by a plurality of candidate auxiliary base stations through the judgment of the target side.
