However, the capabilities of different wireless communication networks are unbalanced, and the capabilities of the terminals are also unbalanced. For example, some base stations support extended bearer identification, while some base stations do not support extended bearer identification; for example, some The terminal supports the extended bearer identifier, and some terminals do not support the extended bearer identifier; for example, some mobility management entities (such as Mobility Management Entity (MME) or access mobility management function (Access and Mobility Management Function) , AMF), etc.) support extended bearer identity assignment, while some mobility management entities do not support extended bearer identity assignment. In this way, it is necessary to select a suitable network service unit for the terminal supporting the extended bearer, so that the terminal can use the maximum number of bearers and improve the service quality of the service, and how to select a suitable network service unit for the terminal becomes an important problem to be solved. .

In an implementation, currently, in a wireless communication network, the number of bearers that the network unit supports for the same terminal at the same time does not normally exceed a preset number threshold. For example, a bearer that is simultaneously established for the same terminal is supported in the 4G network. The maximum number of terminals is 8. However, with the continuous development of communication technologies and the increasing number of services, the number of terminals is increasing. To accommodate the number of terminals, the maximum number of terminals can be loaded. The bearer is extended to 11, 15 or more, and each bearer is provided with a corresponding bearer identifier (such as a logical channel identifier (LCID), etc.), and the extended bearer is also provided with a corresponding bearer identifier. However, the capabilities of different wireless communication networks may be unbalanced and the capabilities of the terminals may be unbalanced. For example, some base stations support extended bearer identification, and some base stations do not support extended bearer identification; for example, some terminals support extended bearer identification, and some terminals do not support extended bearer identification; for example, some Mobile management entities (such as MME or AMF, etc.) support extended bearer identity assignments, while some mobility management entities do not support extended bearer identity assignments. In this way, it is necessary to select a network element of a suitable service terminal for the terminal supporting the extended bearer, so that the terminal can use the maximum number of bearers and improve the service quality of the service.

The embodiments of the present disclosure provide a method for selecting a network unit, a network unit, and a terminal, so as to implement a suitable network service unit for the terminal, so that the terminal can use the maximum number of bearers to improve service quality.

The embodiment of the present disclosure provides a computer readable storage medium. The extended bearer information includes at least one of the following: the extended bearer information supported by the terminal, the extended bearer information supported by the second network unit, and the first network. The unit supports the extended bearer information, and selects the target network unit from the one or more second network units according to the obtained extended bearer information, so that only the extended bearer information supported by the terminal and the second network unit support are supported.

In the 1990s, improvements to a technology could clearly distinguish between hardware improvements (eg, improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (for process flow improvements). However, as technology advances, many of today's method flow improvements can be seen as direct improvements in hardware circuit architecture. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. Designers program themselves to "integrate" a digital system on a single PLD without having to ask the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, today, instead of manually making integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in programming development, but before compiling The original code has to be written in a specific programming language. This is called the Hardware Description Language (HDL). HDL is not the only one, but there are many kinds, such as ABEL (Advanced Boolean Expression Language). AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., are currently the most commonly used VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be apparent to those skilled in the art that the hardware flow for implementing the logic method flow can be easily obtained by simply programming the method flow into the integrated circuit with a few hardware description languages.

The controller can be implemented in any suitable manner, for example, the controller can take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (eg, software or firmware) executable by the (micro)processor. In the form of logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, The Microchip PIC18F26K20 and the Silicone Labs C8051F320, the memory controller can also be implemented as part of the memory's control logic.
