The firewall can realize the switching between the local area network and the public network at the same time, or the two networks can exist at the same time. The invention realizes the application of core network networking to be extended to some large-scale office places and some enterprises that need private networks.
[0038] In order to make the technical solution of the present invention clearer, the following describes the implementation method of the present invention in detail with reference to the accompanying drawings and embodiments:
[0039] The specific construction scheme of the present invention is as follows image 3 As shown, as follows
[0040] Build a five-in-one core network EPC system in a server (the core network EPC system contains five logical network elements: mobility management module (MME), service gateway (S-GW), data gateway (P-GW), Home Subscriber Server (HSS) and Policy and Charging Rules Function Unit (PCRF)), in the core network to activate the USIM card account for the UE to be accessed;
[0041] The switch connects to the GPS, configures the switch 1588 clock source, outputs the synchronization signal, and divides two VLANs. One VLAN is used as the base station and core network EPC transmission, and the other VLAN is used as the core network EPC to connect to the game server or external network.
[0042] Select the base station, configure the base station frequency, MME IP, base station IP and other related parameters to open the station.
[0043] The mobile phone connects to the specially made USIM card to connect to the base station. After the mobile phone is attached to the base station, the mobile phone can communicate with the game server for business;
[0044] According to the arrangement on the competition field, reasonably adjust the base station parameters and output power to ensure that each mobile phone can receive well.
[0045] In summary, it is relatively simple to set up and has greater flexibility. You can consider not building a clock server as needed. The base station is directly connected to the core network EPC to reduce equipment applications. At the same time, the application is not limited to the LAN, as long as the core network EPC SGI The port is connected to the Internet, and data services such as mobile Internet access, movie watching, and online games can be realized by configuring the channel.
[0046] The wireless communication system applied to game competition provided in this embodiment solves the game competition scene that cannot be satisfied by WIFI and 4G on the live network by applying a special customized application to the core network EPC application scenario.
[0047] The wireless communication system applied to game competition provided by the embodiment of the present invention has the main advantages of dedicated and flexible configuration of private networks, high security and fair sharing of network resource connections for each user. At the same time, the use of 4G's strong anti-interference ability and high transmission stability can ensure the stability of the wireless network during the competitive game. Secondly, this new model realizes the characteristics of low-latency networking by optimizing the delay of each network element. At the same time, in terms of network controllability, the present invention can monitor the status of the base station and the status of each UE in real time by connecting to the network management equipment or directly logging in to the base station equipment. When a problem is encountered, the problem can be found in time through the analysis of signaling and data and corresponding Adjustment. 4G uses a unique encryption mechanism, and data is not easily intercepted. The core network EPC only accepts users who have opened an account in it, effectively preventing illegal users from intruding. The base station selected for the application of the present invention can be selected according to different frequency bands and different systems, and the available frequency range is wide. The rate of each UE can be restricted in the EPC of the core network, ensuring the balance of the resources of each UE under the limited bandwidth. At the same time, the core network EPC processing capacity is tens of thousands. As long as the base station is selected properly, a single cell can meet the online needs of hundreds of users, and multiple cells can meet the needs of thousands of users, which can basically meet the needs of large-scale mobile competitive games. . The present invention can increase the 1588 clock source to synchronize the time of the base station when necessary, so as to ensure that in some large venues, in the same local area network, users can smoothly switch between multiple cells, and the range of user activities is wider.
