example

[0065] The simulation environment takes a single cell in the WCDMA network, and the uplink load is 50%. In the case of only voice call AMR12.2 services, the number of simultaneous call users in the single cell is 50, that is, there are 50 call channels.

[0066] The simulation is divided into two situations: one is the situation where only authorized users access, and the other is the situation where both authorized users and non-authorized users access.

[0067] After the simulation of the two cases is completed, statistical analysis is carried out on the use of 50 call channels in the system, and a comparison chart of the use of call channels in the two simulation cases is obtained, as shown in Figure 5 .

[0068] from Figure 5 It can be seen that when only authorized users access, the maximum utilization rate of each communication channel in the system is only 50%, while when both authorized users and unauthorized users access, the utilization rate of each communication ...

Abstract

The invention discloses a communication system capable of having cognitive function based on WCDMA network, mainly for solving the problem of frequency spectrum unreasonable utilization in WCDMA network. The invention is characterized by: adding an IEEE1900.4 defined cognition module in a WCDMA network, wherein a cognitive module service operator spectrum manager (OSM) and a network reconfiguration manager (NRM) are added in a core network (CN), a RAN reconfiguration controller (RRC) and a radio access RAN measure collector (RMC) are added in an UMTS terrestrial radio access network (UTRAN), and a cognitive module terminal reconfiguration manager (TRM), a terminal reconfiguration controller (TRC) and a terminal measure collector (TMC) are added in an user equipment (UE); and defining the transmission message format between the NRM and a mobile switching center (MSC), the RRC and a radio network controller (RNC). Using the system of the invention, users can realize the communication between the unauthorized users and authorized users, therefore the frequency spectrum utilization rate in the system is raised and the irrationality of using frequency spectrum is reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and designs a communication system with a cognitive function based on a WCDMA network, which is used for improving the utilization rate of wireless spectrum resources. Background technique [0002] The rapid development of wireless communication has made people's demand for wireless spectrum grow rapidly. However, the original spectrum utilization strategy in wireless communication has shown the lack of spectrum resources under the current situation of increasing communication services. In the existing spectrum allocation strategy, an authorized user can be allocated to a certain frequency band for communication. Even if the user does not use this frequency band, other users have no right to use it. When monitoring the wireless spectrum for a long time, it will be found that some spectrum is occupied for a long time, some spectrum is only occupied part of the time, and some spectr...
