Latest Patents

One of Baikui Xu's latest patents is a mobile communication method that utilizes a mobile communication terminal. This method allows the communication unit of the terminal to operate in at least two communication modes. The antenna assembly is designed to selectively work in different communication modes or in a combination of modes. The method involves selecting a coupling relationship between the antenna assembly and the communication unit based on the communication mode and service type. This innovation results in a mobile communication terminal that is compact, cost-effective, and easier to design.

Another notable patent is a method for fast call setup in a mobile communication system. This invention outlines a series of steps for establishing a radio resource control (RRC) connection, Non-access stratum (NAS) signaling connection, and radio access bearer (RAB) setup. The user equipment sends an RRC CONNECTION REQUEST encapsulating NAS to the radio network controller (RNC). The RNC processes this request and forwards the NAS to the core network, which initiates the RAB Assignment Request and begins paging the terminal call.
