[0004] However, the wireless communication system has begun to evolve into the fifth generation (5th generation, 5G) wireless communication system. The terminal equipment performs data transmission through the dual connection (DC) communication system composed of the LTE system and the NR system. However, the current protocol does not There is no definition of how the base station (gNB) in the new radio interface (new radio, NR) system obtains the type information of the terminal equipment (user equipment, UE). Therefore, a set of solutions that can help gNB obtain the type information of the terminal equipment Urgent release

Embodiment Construction
[0050] The embodiment of the present application provides a request processing method, a related device, and a system. The first base station can obtain the UE type information of at least one UE from the first base station addition request sent by the second base station, and provides the UE type information obtained by the second base station. scheme of information.
[0051] The terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, and this is merely a description of the manner in which objects with the same attribute are described in the embodiments of the present application. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-ex...

The embodiment of the present application discloses a request processing method, a related device and a system. The first base station can obtain the UE type information of at least one UE from the first base station addition request sent by the second base station, which provides the UE type information obtained by the second base station. scheme of information. The method includes: the first base station receives the first base station addition request message sent by the second base station; when the first base station addition request message includes UE type information of the terminal equipment UE, the first base station determines the UE's UE type information according to the first base station addition request message. Type; wherein, the first base station is a new air interface NR base station, and the second base station is a long-term evolution LTE base station.
Description
technical field [0001] The present application relates to the communication field, and in particular to a request processing method, related device and system. Background technique [0002] New features are constantly being released in the wireless communication system, and there are more and more brands and models of terminal equipment. Different types of terminals may support different features, that is, not all features introduced by the wireless communication system can be used by all types. terminal support. When the features used by the base station are not supported by the terminal equipment, abnormal call drop is likely to occur, which reduces system performance. [0003] In a long term evolution (LTE) system, the 3GPP protocol defines the transfer process of UE type information between a mobility management entity (mobility management entity, MME) and an evolved base station (evolutional node B, eNB or eNodeB), It also defines the transfer process of the type info...
