Embodiment 1

[0058] see figure 1 As shown, the embodiment of the present invention provides a service node update method, executed by a terminal device, the method may include:

[0059] Step 101: Receive configuration information.

[0060] It should be noted that the service node update method provided by the embodiment of the present invention is applicable to various scenarios where service node update is required. For example, switching the serving node (Handover), or replacing the secondary node (SNchange), etc. Specifically, in the scenario of performing service node handover (Handover), the source node may be specifically a source base station, and the target node may be specifically a target base station. In the scenario of replacing a secondary node (SN change), the source node may specifically be a source secondary node SN, and the target node may specifically be a target secondary node SN. It can be understood that the connection structure of the terminal device before the upd...

Embodiment 2

[0100] Referring to 2, corresponding to the service node update method performed by the terminal device and the service node update method performed by the target node, an embodiment of the present application provides a service node update method, which is performed by the network side device, wherein the network The side device includes the source node in the update process of the service node. The method includes:

[0101] Step 201: Send configuration information, the configuration information includes the first connection configuration information used to maintain the connection between the source node and the target node during the service node update process, and the second connection used to release the connection with the source node and connect with the target node configuration information.

[0102] It can be understood that the configuration information sent by the source node when it executes step 201 corresponds to the configuration information received by the te...

Embodiment 3

[0118] see Figure 5 As shown, corresponding to the service node update method performed by the terminal device and the service node update method performed by the source node, the embodiment of the present application also provides a service node update method, which is performed by the network side device, wherein the network side device Include the target node in the service node update process. The method includes:

[0119] Step 301: Receive the first source node state transition message sent by the source node in the serving node update process and the first PDCP PDU received from the source node to detach the bearer.

[0120] It can be understood that the first source node status transfer (SN status transfer) message received by the target node from the source node in step 301 is different from the first source node status sent to the target node by the source node in step 203 in Embodiment 2. Corresponding to the conversion message, the target node performs step 301 a...

Abstract

The present invention discloses a method for updating a service node, which is executed by a terminal device. The method includes: receiving configuration information, the configuration information including first connection configuration information used to maintain the connection between the source node and the target node during the update process of the service node, and The second connection configuration information used to release the connection with the source node and connect with the target node; apply the first connection configuration information to process the layer 2 protocol entity corresponding to the bearer between the terminal device and the source node, and reload the bearer It is configured as a source node separated bearer; the second connection configuration information is applied to process the layer 2 protocol entity corresponding to the bearer, and the source node separated bearer is reconfigured as a target node bearer. The invention also discloses a service node updating method executed by the network side equipment. The present invention can realize continuous and uninterrupted user plane data during the updating process of the serving node.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service node updating method, terminal equipment and network side equipment. Background technique [0002] In related mobile communication systems, when a terminal device moves from one cell (i.e., the coverage area of ​​a base station) to another cell, or the communication quality in the cell decreases due to external interference, in order to maintain the communication of the terminal device, it is often necessary to replace the service node. When updating the service node, the terminal device needs to disconnect from the source node before establishing a new connection with the target node. Therefore, this service node update method will cause data interruption on the user plane and affect user experience. [0003] With the development of mobile communication technology, 5G (5Generation, fifth generation) mobile communication system came into being. In order to improve w...
