Problems solved by technology

This implementation has obvious deficiencies: 1) Any base station in the same routing area needs to periodically interact with load messages. When there are many base stations, it will waste system resources and increase system overhead; 2) Each base station needs to know The load information of all base stations in the routing area where it is located requires each base station to save a large amount of data; 3) When sending a handover across routing areas, the serving base station needs to know the list of base stations in the routing area where the anchor base station is located
When the anchor base station fails, because the serving base station does not know the load information of the base stations in the routing area where the anchor base station is located, the serving base station can only establish contact with the base station in the routing area where the anchor base station is located, and request the target base station to take over the original anchor base station For users, this implementation will lead to low efficiency of anchor replacement

Embodiment 1

[0042] Embodiment 1: Please refer to the attached Figure 4 , the management entity EMS indicates that the base station is busy and triggers the process of changing the anchor base station, which includes:

[0043] Step 201, the EMS judges that the base station is busy by the degree of busyness of the base station, then it sends a base station busy indication message to the base station;

[0044] Step 202, after receiving the message, the original anchor base station records that it is busy. This state will not have any impact on the existing tunnel, but for the tunnel establishment request received later, after the original anchor base station replies the tunnel establishment reply, it will immediately notify the tunnel establishment party that "the anchor base station is busy";

[0045] Step 203, the serving base station sends a tunnel establishment request to the original anchor base station;

[0046] Step 204, the original anchor base station finds that its tunnel is busy,...

Embodiment 2

[0056] Embodiment 2: Please refer to the attached Figure 5 , the anchor base station fails, and the serving base station triggers the process of replacing the anchor base station; this failure causes the establishment of the tunnel between base stations to fail. The process includes:

[0057] Step 301, the wireless terminal initiates a data service registration request to the base station, sends a DataServiceRequest message, carrying the IPlist data of the current terminal connection, including attributes such as ip address, mac address, ip type, and session type;

[0058] Step 302, the base station returns a DataServiceResponse message to the terminal;

[0059] Step 303, the base station judges the terminal iplist data, judges that the anchor base station to which the IP belongs is another base station, and sends a tunnel establishment request message to the anchor base station, carrying the terminal id, and the port used for establishing the tunnel;

[0060] Step 304, the...

Embodiment 3

[0066] Embodiment 3: Please refer to the attached Figure 6 , the anchor base station fails, and the serving base station triggers the flow chart of replacing the anchor base station. This failure caused the heartbeat message reception of the tunnel between base stations to fail. The process includes:

[0067] Step 401, the wireless terminal initiates a data service registration request to the BS, and sends a DataServiceRequest message, carrying IPlist data currently connected to the terminal, including attributes such as ip address, mac address, ip type, and session type;

[0068] Step 402, the base station returns a DataServiceResponse message to the terminal;

[0069] Step 403, the base station judges the terminal iplist data, judges that the anchor base station to which the IP belongs is another base station, and sends a tunnel establishment request message to the anchor base station, carrying the terminal id, and the port used to establish the tunnel;

[0070] Step 404...

Abstract

The invention proposes a method for replacing a terminal anchor base station. The method includes the following steps that: base stations report idleness degree parameters to a management entity; the management entity calculates the idleness degree of each base station and transmits idleness indication messages to the base stations; when an anchor base station is busy, and a service base station establishes a tunnel with the anchor base station, the anchor base station transmits an anchor base station busy indication to the service base station to prompt the service base station to replace the anchor base station; and the service base station performs anchor base station replacement operation according to the prompting of the anchor base station. With the method of the invention adopted, the load of the base stations can be adjusted autonomously, and the problem of excessively high load of the base stations can be solved, and improvement of the stability of a network can be benefitted, and user experience can be enhanced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for replacing a terminal anchor base station. Background technique [0002] In a multi-base station network, due to uneven user services and geographical distribution, traditional access will cause unbalanced loads on base stations, which will further reduce the overall utilization of the wireless network and the decline in user QoS. [0003] Usually, base station load balancing is performed manually, based on long-term base station observation data. When the base station is frequently overloaded, adjust the relevant system parameters of the base station to ensure the normal operation of the base station. However, this method will cause frequent manual adjustment of base station system parameters for locations where the base station load changes greatly over time. At the same time, once the anchor base station fails, the service data of a large number of terminals a...
