Embodiment 1

[0058] See figure 1 As shown, the embodiment of the present invention provides a method for updating a service node, which is executed by a terminal device, and the method may include:

[0059] Step 101: Receive configuration information.

[0060] It should be noted that the service node update method provided in the embodiment of the present invention is applicable to a variety of scenarios that require service node update. For example, handover of the service node (Handover), or replacement of the secondary node (SNchange), etc. Specifically, in the scenario of performing a handover of a serving node (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 changing the secondary node (SN change), the source node may specifically be the source secondary node SN, and the target node may specifically be the target secondary node SN. It can be understood that the connection architecture ...

Embodiment 2

[0100] As shown in 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 executed 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 keep the source node and the target node connected 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 performing step 201 corresponds to the configuration information received by the terminal device performing step ...

Embodiment 3

[0118] See Figure 5 As shown, corresponding to the service node update method executed by the terminal device and the service node update method executed by the source node, an embodiment of the present application also provides a service node update method, which is executed by the network side device, wherein the network side device Including 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 service node update process and the first PDCP PDU received from the source node to separate the bearer.

[0120] It can be understood that the target node executes the first source node status transfer (SN status transfer) message received from the source node in step 301, which is the same as 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 executes the fi...

Abstract

The invention discloses a service node updating method executed by terminal equipment. The method comprises the following steps: receiving configuration information which comprises first connection configuration information used for simultaneously keeping connection between a source node and a target node in a service node updating process and second connection configuration information used for releasing connection with the source node and connecting with the target node; processing a layer 2 protocol entity corresponding to the bearer between the terminal equipment and the source node by using the first connection configuration information, and reconfiguring the bearer as a source node separation bearer; and processing the layer 2 protocol entity corresponding to the bearer by applying the second connection configuration information, and separating the bearer from the source node and reconfiguring the bearer as a target node bearer. According to the invention, in the updating processof the service node, continuous uninterrupted data of a user plane can be realized.

Description

Technical field [0001] The invention relates to the field of communications, and in particular to a method for updating a service node, terminal equipment and network side equipment. Background technique [0002] In related mobile communication systems, when terminal equipment moves from one cell (that is, the coverage area of ​​the 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 equipment, it is often necessary to change services node. When updating the service node, the terminal device needs to disconnect from the source node before it can establish a new connection with the target node. Therefore, this service node update method will cause user data interruption and affect user experience. [0003] With the development of mobile communication technology, 5G (5Generation, the fifth generation) mobile communication system came into being. In order to improve wi...
