Technical Field

Background

In the existing system, whether the network side uses the conditional synchronous reconfiguration flow or the traditional synchronous reconfiguration flow depends on the realization of the network side, but because the network side cannot effectively acquire the information related to the terminal in the existing mechanism flow, for example: the method comprises the steps that the terminal speed information, the terminal movement history information and the like are obtained, the network side cannot flexibly use the conditional synchronous reconfiguration and the traditional synchronous reconfiguration process, the robustness of the terminal movement is reduced when the traditional synchronous reconfiguration is used, and the resource utilization rate of the network side is reduced when the conditional synchronous reconfiguration is used.

As can be seen from the above, the network side needs to balance between the robustness of terminal synchronous reconfiguration (conditional synchronous reconfiguration) and the efficient utilization of resources (traditional synchronous reconfiguration), and there is no related scheme in the prior art, which results in that the resources of the network side cannot be efficiently utilized and the performance balance between the terminal and the network side cannot be achieved.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

To facilitate the description of the present solution, first, the related prior art solution is introduced:

the NR (new air interface) condition synchronization reconfiguration mechanism in the prior art is as follows:

the general idea of conditional synchronous reconfiguration is that a network side issues a synchronous reconfiguration command to a terminal in advance, the terminal does not initiate a synchronous reconfiguration process in a synchronous reconfiguration target cell like a traditional synchronous reconfiguration process immediately after receiving the conditional synchronous reconfiguration command, but stores the configuration in the synchronous reconfiguration command, the synchronous reconfiguration process is not initiated in the target cell until a target cell signal meets the condition configured in the synchronous reconfiguration command, and one conditional synchronous reconfiguration command allows the synchronous reconfiguration configuration of one or more target cells to be configured.

The advantages of the above mechanism are: the problem of terminal movement robustness is solved, the traditional synchronous reconfiguration process is triggered by a network side, but the network side does not know the accurate movement direction of the terminal, wrong judgment happens occasionally, although the conditional synchronous reconfiguration configuration process is also triggered by the network side, the terminal can judge which target cell is accessed according to a signal monitored by the terminal, and the success rate and the accuracy of the synchronous reconfiguration can be increased because the terminal judges that a synchronous reconfiguration target can reflect the actual condition of the terminal better than the network side; on the other hand, for a terminal moving at a high speed, the traditional synchronous reconfiguration process is too slow, the terminal measures the time interval between the report and the receipt of the synchronous reconfiguration of the network side, so that the terminal is likely to not receive the synchronous reconfiguration command or receive the untimely synchronous reconfiguration command, the conditional synchronous reconfiguration allows the network side to issue the synchronous reconfiguration command to the terminal in advance, and the problem that the terminal cannot receive the synchronous reconfiguration command at the high speed is relieved to a certain extent.

The disadvantages of the above mechanism are: the conditional synchronous reconfiguration allows the network side to reserve one or more target cell resources to the terminal in advance, but the terminal only selects one target cell meeting the trigger condition to complete the synchronous reconfiguration process, so that the network side needs to comprehensively consider the condition synchronous reconfiguration or the traditional synchronous reconfiguration process, and the excessive use condition synchronous reconfiguration process can reduce the use efficiency of the network side resources.

Specifically, as shown in fig. 1, the primary serving cell conditional synchronization reconfiguration procedure initiated by the primary serving cell includes:

step 11: the network side (source primary cell) synchronously reconfigures and changes the primary service cell based on the implementation decision use condition;

step 12: the network side (source main cell) informs the terminal of conditional synchronization reconfiguration information for replacing the main service cell generated by the network side through a reconfiguration message;

step 13: after a conditional synchronization reconfiguration condition of a certain target cell configured by a main serving cell (a source main cell) is triggered, a terminal initiates a synchronization process in the target cell (a target main cell).

The adding of the secondary cell group is initiated by the primary serving cell, and the process is shown in fig. 2, that is, the conditional adding process of the secondary cell group initiated by the primary serving cell, as shown in fig. 2, includes:

step 21: a main service cell (a source main cell) initiates a secondary cell group condition adding request to a main secondary cell;

step 22: after the main and auxiliary cells agree with an auxiliary cell group condition adding request initiated by the main service cell, adding auxiliary cell group condition configuration information into an auxiliary cell group adding confirmation message;

step 23: after receiving the confirmation message containing the auxiliary cell group condition synchronous configuration information, the main service cell informs the terminal of the auxiliary cell group condition synchronous configuration information by using an idle port reconfiguration message (sends the synchronous reconfiguration message containing the auxiliary cell group condition synchronous configuration information to the terminal);

step 24: after successfully receiving a reconfiguration message of which the air interface contains auxiliary cell group condition synchronous configuration information, the terminal informs a main service cell that the auxiliary cell group condition synchronous reconfiguration is successful by using a synchronous reconfiguration successful message;

step 25: the main service cell forwards the message of successful conditional synchronous reconfiguration of the auxiliary cell group to the main and auxiliary cells;

step 26: if the auxiliary cell group condition synchronization configuration information contains the auxiliary cell group radio bearer configuration, the terminal needs to establish a synchronization process with the auxiliary cell group through step 26; if the secondary cell group configuration information does not contain the secondary cell group radio bearer configuration, step 26 does not exist.

Specifically, a conditional synchronization reconfiguration mechanism is introduced into an NR (new air interface), and the mechanism allows a network side to configure resources of multiple target cells for a terminal in one conditional synchronization reconfiguration process, and the conditional synchronization reconfiguration mechanism has the advantage of solving the problem of high-speed mobility robustness of the terminal, and has the disadvantage that one or more cells are required to reserve resources for the terminal in advance, but the terminal can only access one cell at most, and the remaining reserved resources of the cells which are not accessed are wasted, that is, the conditional synchronization reconfiguration mechanism is not always superior to the conventional synchronization reconfiguration mechanism.

In combination with the above, the present invention provides a synchronous reconfiguration method, applied to a terminal, for solving the problem that a synchronous reconfiguration scheme in the prior art cannot achieve performance balance between the terminal and a network side, as shown in fig. 3, including:

step 31: receiving synchronous reconfiguration information sent by a network node according to the synchronous reconfiguration related historical information of the terminal;
