Problems solved by technology

[0011] The Chinese patent application publication number is CN102857906A, and the title of the invention is "Method, Device and System for Switching Activation Numbers in One-Card Multi-Number Service", which describes a method for changing multiple numbers according to CELL-id, without involving the load of the base station Policies and IMSI replacement, etc.
[0013] General-purpose wireless user terminals UT generally only use one IMSI number, and then use the IMSI number to attach to a base station of a corresponding network, but cannot attach to base stations of other networks, and cannot solve the problem of network service quality degradation caused by heavy base station loads
At the same time, IMSIs belonging to the same network can only attach to the base station of the network, and cannot switch base station attachment

Embodiment 1

[0051] In the method of the present invention, the current base station is connected to the core network where the core network is located, and the core network detects the wireless user terminal UT connection quantity (Ue_Amount) of the base station in real time, and counts the bearer quantity (Bear_Amount) provided by the base station according to the bear_id (bearer identifier), and counts the flow through The traffic (Traffic_Amount) of the gateway GGSN / PGW is comprehensively calculated and a new variable (Over_Load_Max) is used to represent the load of the current base station. When the user terminal attaches to the base station, the core network will establish a default bearer to the user terminal. If a user applies for or uses certain services, in order to ensure the QoS requirements of this service, the core network establishes a dedicated bearer on the basis of the default bearer. Each bearer (default and dedicated) will have its own identity. Compare the load (Over_...

Abstract

The present invention provides a method for a user terminal to switch base station attachment. The core network monitors the load of the current base station in real time; when the user terminal initiates an attach request to the current base station, the core network determines that the load of the current base station is greater than a preset threshold; if so, the core network The network uses the air number writing technology to write a new IMSI number to the user terminal through the air interface OTA. After the user terminal restarts, it uses the new IMSI number to attach to other base stations; if not, the user terminal successfully attaches to the current base station. The invention ensures that the user terminal will not access the base station with heavy load, achieves the purpose of switching base station attachment, avoids long-term high load operation of the base station, reduces user experience, and improves service quality for wireless users.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for a user terminal to switch base station attachment. Background technique [0002] In the 3G / 4G / 5G wireless network, the base station is the interface device for the mobile device to access the core network, and the core network also sends data or responds to the mobile device through the base station. [0003] The user terminal initiates a registration request to the core network by attaching to the base station. After the relevant network elements of the core network are verified, the user registration is successful, and a session is established through the core network to complete communication. However, the wireless resources of the base station are limited, and there is a certain limit for the base station to connect to user terminals. There is also an upper limit for the bearer connection provided by a single base station for wireless users. ...
