Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
Fig. 1 shows a flowchart of a dual connectivity configuration processing method of a terminal according to this embodiment, which includes:
s101, after receiving a switching request sent by a source base station, if the switching preparation is judged to be successful, the target base station judges whether protocol versions supported by the source base station and the target base station are consistent.
Wherein, the target base station is a base station of a 4G network supporting R15 and above protocol versions.
The source base station is a base station connected to a 4G network of a plurality of terminals to be switched, and may support R15 protocol version, or may not support R15 protocol version but only support R13 and R14 protocol version.
Specifically, after receiving a handover request sent by a source base station, a target base station needs to perform a preparation operation, and when the handover preparation of the target base station is successful, a handover preparation response message is returned to the source base station. And if the switching preparation of the target base station fails, returning a switching preparation failure message, finishing the subsequent process and not executing any more.
And the terminal to be switched requests to be switched to the target base station and the 5G base station from the source base station so as to be connected to the target base station and the 5G base station simultaneously, so that a double-connection terminal is realized. It should be noted that the terminal to be switched may be switched to the target base station only, and does not perform dual connectivity.
And the switching request is a request for switching to a target base station and a 5G base station, which is sent to the source base station after the terminal to be switched reports the measurement report, and the source base station forwards the switching request to the target base station if the switching request is judged to meet the switching condition after receiving the switching request.
And S102, if the protocol versions supported by the source base station and the target base station are judged to be consistent, configuring measurement information according to the terminal capability carried by the switching request after the terminal switching is completed and the target cell is successfully accessed, otherwise, triggering a terminal capability query to acquire the terminal capability after the terminal switching is completed and the target cell is successfully accessed.
S103, if the first target terminal is judged to have the double-connection capability, the first target terminal is configured with double-connection measurement, and after a report to be measured is reported, the first target terminal is configured with a double-connection function.
The first target terminal is a terminal which supports a dual connection function in the terminal to be switched.
Specifically, after the target base station confirms that the protocol version of the source base station is not the protocol version above R15 and R15 and the random access is successful, a process of terminal capability query is initiated to the terminal, that is, a ue capability inquiry message is sent to the terminal; after the UE capability information message is replied by the terminal, storing the queried terminal capability in a context of a UE (User Equipment), when the capability of the terminal supports the enb c function, configuring measurement and other measurement configurations related to the enb c for a first target terminal (a terminal supporting a dual connectivity function in a terminal to be switched) according to the terminal capability, and reporting a corresponding measurement report to a base station of a 4G network, where the base station of the 4G network initiates an SgNB adding process after receiving the measurement report, so as to implement dual connectivity of the first target terminal, that is, to connect to the target base station and the base station of the 5G network at the same time. When the terminal supporting the ENDC function is switched from the eNB to the MeNB, the MeNB acquires whether the terminal supports the ENDC function or not through judgment of the protocol version of the source base station and re-inquiry of the UE capability, and ensures that the terminal supporting the ENDC function can complete double-connection perception to the maximum extent under the base stations of the protocol versions above R15 and R15.
In this embodiment, by distinguishing a situation that protocol versions supported by a source base station and a target base station are consistent, configuration of measurement information is performed on a terminal capability or a terminal capability is acquired, and configuration of a dual connectivity function is performed on a terminal with dual connectivity capability, so that the terminal supporting dual connectivity is switched from an eNB base station to an MeNB base station, and in a situation that the terminal capabilities of protocol versions above R15 and R15 are lost, the terminal can be guaranteed to perform dual connectivity, an endec function is supported to the maximum extent, network resources are fully utilized, and the base stations of protocol versions above R15 and R15 can be better used.
Further, on the basis of the above method embodiment, the determining, in S101, whether the protocol versions supported by the source base station and the target base station are consistent specifically includes:
s1011, obtaining the source cell information and the target cell information in the switching preparation message.
The source cell information is cell information corresponding to the source base station, and the target cell information is cell information corresponding to the target base station.
S1012, searching corresponding adjacent cell relation information according to the target cell information, and searching corresponding protocol version attribute in the source cell information according to the adjacent cell relation information.
And S1013, judging whether the protocol versions supported by the source base station and the target base station are consistent or not according to the protocol version attribute.
Specifically, a schematic flow chart of determining the protocol versions supported by the source base station and the target base station is shown in fig. 2, and when a protocol version determination scenario is triggered, information of a source Cell and a target Cell is obtained in a handover preparation message, where the information includes PCI (Physical Cell Identifier) of the source Cell and Cell ID (Cell Identity) information of the target Cell; and then, searching corresponding adjacent CELL relation information according to the CELL ID of the target CELL, and searching the protocol version attribute of the PCI corresponding to the source CELL in the adjacent CELL relation of the target CELL.
When the target base station supports R15 and R15 protocol versions above; accordingly, S1013 specifically includes:
and if the protocol version attribute is the protocol version above R15 and R15, determining that the protocol versions supported by the source base station and the target base station are consistent, otherwise, determining that the protocol versions supported by the source base station and the target base station are inconsistent.
Namely, finally, whether the protocol version of the source cell is configured to be the protocol version above R15 and R15 is judged, and the two cases are divided: if the attributes are protocol versions above R15 and R15, the protocol versions are considered to be consistent; if the attribute is not the protocol below R15, the protocol version is considered inconsistent.
It should be noted that, here, the protocol version attribute is configured by the network operation and maintenance personnel.
By judging whether the protocol versions supported by the source base station and the target base station are consistent or not, different configuration processing of the dual connection function of the terminal to be switched is conveniently carried out subsequently according to different results.
Further, on the basis of the above embodiment of the method, the method further comprises:
and S104, if the second target terminal is judged not to have the double-connection capability, the second target terminal is configured with the connection state mobility measurement.
And the second target terminal is a terminal which does not support the double-connection function in the terminal to be switched.
When the second target terminal in the switched terminals does not support the dual connectivity function, the target base station configures other measurement configurations, such as configuration of connection state mobility measurement, for the terminals according to the terminal capabilities, except for the ENDC.
A specific terminal dual-connection configuration processing method is shown in fig. 3, and includes the following specific steps:
the method comprises the following steps: preparing;
step two: the R15 protocol version base station receives the request for preparing switching between base stations, and the switching preparation is successful, and returns a response message of switching preparation to the source base station; if the switching preparation fails, returning a switching preparation failure message, and ending the process;
step three: judging whether the protocol versions of the switching source base station and the base station are consistent, and dividing the protocol versions into two conditions:
if the protocol versions are consistent, entering the step four;
if the protocol versions are not consistent, entering a sixth step;
step four: the terminal completes random access in the target base station;
step five: configuring corresponding measurement according to the UE capability carried by the source side base station, and entering the step eleven;
step six: the target base station initiates a UE capability query process after the terminal is successfully accessed randomly; namely, the ue capability inquiry message is sent to the terminal.
Step seven: after the terminal replies the UECapabilityinformation message, storing the inquired UE capability into the UE context;
step eight: judging whether the ENDC function is supported or not according to the UE capability fed back by the terminal, and dividing the situation into two situations:
supporting the ENDC function in the terminal capability, and entering the step nine;
the ENDC function is not supported in the terminal capability, and the step ten is entered;
step nine: configuring ENDC related measurement (measurement of gNB cell) and other measurement configuration for the terminal according to the terminal capability; when the terminal meets the ENDC measurement, reporting a corresponding measurement report, and initiating an addition process of the SgNB by the base station to realize double connection; entering the step eleven;
step ten: configuring other measurement configurations except ENDC for the terminal according to the terminal capability;
step eleven: the flow ends.
In this embodiment, by judging the relationship between the protocol versions of the handover source cell and the target cell, when the protocol versions are inconsistent, a query process of the terminal capability is initiated in the target cell, so that the endec function of the UE is obtained, the measurement of the gNB cell is configured for the terminal supporting the endec function, when the terminal satisfies the endec measurement, a corresponding measurement report is reported, the base station initiates an addition process of the SgNB, dual connectivity is realized, and the perception of the terminal supporting the endec function is ensured to the maximum.
