Problems solved by technology

It can be seen that the functions of each network element in the network are very fixed, especially when the user terminal performs handover operations, it is impossible to establish a link flexibly according to the actual situation, so as to ensure that the new base station can quickly obtain all the downlink information in the communication process of the user terminal , thereby reducing the operating efficiency of the network

Embodiment 1

[0042] This embodiment provides a handover control method, which is applied to a network control device, such as figure 1 As shown, the method includes:

[0043] Step 101: Receive a handover request from a user terminal, select a new base station for the user terminal according to the handover request, send a handover instruction to the user terminal, and receive a response that the user terminal is handed over;

[0044] Step 102: control the establishment of a communication link between the original base station and the new base station, and generate a control instruction;

[0045] Step 103: Send a control command to the original base station, so that the original base station obtains data that meets the second preset condition, and sends the data to the new base station through the communication link; wherein the second preset The condition is that after the user terminal switches to the new base station, the original base station receives downlink data for the user termina...

Embodiment 2

[0071] This embodiment provides a network control device, such as Figure 4 As shown, the network control device includes:

[0072] The communication unit 41 is configured to receive a handover request from a user terminal, send a handover instruction to the user terminal, and receive a response that the user terminal is handed over; send the control instruction to the original base station;

[0073] The processing unit 42 is configured to control the establishment of a communication link between the original base station and the new base station, and generate a control instruction.

[0074] Here, the first network consists of N SDN switches, where N is a positive integer greater than or equal to 1.

[0075] The handover request of the user terminal may be sent by the original base station accessed by the user terminal, or may be sent by the original base station accessed by the user terminal and through the first network.

[0076] The processing unit 42 is specifically conf...

Embodiment 3

[0085] This embodiment provides a switching control system, such as Figure 5 As shown, the method includes:

[0086] The network control device 51 is configured to receive a handover request from a user terminal, select a new base station for the user terminal according to the handover request, send a handover instruction to the user terminal, and receive a response that the user terminal is handed over; control Establish a communication link between the original base station and the new base station, and generate control instructions; send the control instructions to the original base station;

[0087] The original base station 52 is configured to establish a communication link with the new base station according to the control of the network control device, and after receiving the control command sent by the network control device, obtain data that meets the second preset condition according to the control command, and pass The communication link sends the data to the new ...

Abstract

The invention discloses a switching control method, network control equipment and a system. The method comprises the following steps: receiving a switching request of a user terminal, selecting a new base station for the user terminal according to the switching request, sending a switching instruction to the user terminal, and receiving a response of switching completion of the user terminal; controlling and establishing a communication link between an original base station and the new base station, and generating a control instruction; sending the control instruction to the original base station to enable the original base station to acquire data meeting a second preset condition, and sending the data to the new base station through the communication link, wherein the second preset condition is that after the user terminal is switched to the new base station, the original base station receives downlink data aiming at the user terminal.

Description

technical field [0001] The present invention relates to a network management technology in the communication field, in particular to a handover control method, network control device and system. Background technique [0002] The GPRS Tunnelling Protocol (GTP, GPRS Tunnelling Protocol) is a set of communication protocols based on the Internet Protocol (IP), which is used to carry General Packet Radio Service (GPRS, General Packet Radio Service) in GSM, UMTS and LTE networks. In the 3GPP architecture, GTP and various interfaces based on Proxy Mobile IPv6 (Proxy Mobile IPv6) transmit Evolved Packet System (EPS) carriers on multiple interface points, including transmission between the PGW and the new base station. It can be seen that the functions of each network element in the network are very fixed, especially when the user terminal performs a handover operation, it is impossible to flexibly establish a link according to the actual situation, so that the new base station can q...
