Problems solved by technology

If the state of L2 (Layer 2, namely the media access control layer) needs to be reset every time the service node is replaced, it will affect the user experience on the one hand, and on the other hand, the unnecessary retransmission caused by the reset will also reduce the system efficiency, because RLC The reset of the RLC layer will lose some transmission information of the RLC layer. For example, some RLC PDUs (protocol data units) have been successfully transmitted and received positive confirmation from the receiving end. However, the RLC PDU does not contain complete high-level data, but high-level data. For a certain segment, the segment information that has been successfully transmitted will not be retained, which is equivalent to that at the target node, the entire high-level data needs to be retransmitted, including the segment that has been successfully transmitted, resulting in redundant The remaining retransmissions are not conducive to system efficiency and user experience

Embodiment 1

[0167] This embodiment provides an information processing method, which is applied to the first node, such as figure 2 As shown, the method includes:

[0168] Step 101: The first node receives an indication message from the network side, and the indication message indicates to hand over the user terminal under the first node to a second node;

[0169] Step 102: The first node negotiates with the second node to reserve the radio link layer control protocol RLC status information and buffer data of all bearers of the user terminal, so that the second node is The user terminal provides continuous data services.

[0170] Wherein, the indication message may be a handover message or a reconfiguration message.

[0171] Wherein, the first node is a source cell, a source base station or a source secondary node, and the second node is a target cell, a target base station or a target secondary node. The first node and the second node may be located in different devices, or may be two...

Embodiment 2

[0221] This embodiment provides an information processing method, which is applied to the second node, such as image 3 As shown, the method includes:

[0222] Step 201: The second node negotiates with the first node to reserve the radio link layer control protocol RLC status information and buffer data of all bearers of the user terminal, and the user terminal is handed over from the first node to the second node;

[0223] Step 202: The second node provides the user terminal with a continuous data service based on the retained information.

[0224] Wherein, the first node is a source cell, a source base station or a source secondary node, and the second node is a target cell, a target base station or a target secondary node. The first node and the second node may be located in different devices, or may be two different parts of the same device.

[0225] In this embodiment, when the user terminal is handed over, the L2 state is kept as much as possible, so that when the use...

Embodiment 3

[0235] This embodiment provides an information processing method, which is applied to a user terminal, such as Figure 4 As shown, the method includes:

[0236] Step 301: The user terminal receives an instruction message sent by the network side, the instruction message indicates that the user terminal is to be handed over from the first node to the second node, and the instruction message carries an instruction about Layer 2 information processing area;

[0237] Step 302: The user terminal processes layer 2 information according to the indication message, so as to switch from the first node to the second node.

[0238] Wherein, the indication message may be a handover message or a reconfiguration message.

[0239] Wherein, the first node is a source cell, a source base station or a source secondary node, and the second node is a target cell, a target base station or a target secondary node. The first node and the second node may be located in different devices, or may be t...

Abstract

The invention provides an information processing method and an information processing device, belonging to the technical field of communication. The method comprises the following steps that: a firstnode receives an indication message of a network side, wherein the indication message indicates switching a user terminal under the first node to a second node; the first node and the second node performs negotiation to reserve all borne wireless link layer control protocol RLC state information and cache data of the user terminal, and thus, the second node is enabled to provide consecutive data services for the user terminal based on the reserved information. With the technical scheme provided by the invention, UE can be guaranteed to move fast and efficiently between the nodes, user experience of switching between the nodes is promoted, and data transmission efficiency of a network is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information processing method and device. Background technique [0002] In the future development of mobile communication systems, in order to better meet user needs and greatly increase network capacity and throughput, more transmission nodes will be introduced, that is, ultra-dense networks in the future. In the LTE (Long Term Evolution) system, most of the nodes on the network side are connected by wires, such as figure 1 As shown, eNBs (evolved Node B, evolved base stations) are connected by wired links, and eNBs and core network nodes are also connected by wired links. The core network nodes include MME (Mobility Management Entity), S-GW (Serving GateWay, service gateway) and so on. [0003] In the current R8 specification, the typical internal handover process between MME and S-GW is as follows: [0004] The source eNB makes a judgment based on the meas...
