Embodiment Construction
[0034] The system model is shown in Figure 1. C3G-A is an extension of the TD-SCDMA system. This extension does not need to modify or improve the TD protocol and the central infrastructure. It only needs to reconfigure the UE structure and implement protocol conversion. The main application scenarios include:
[0035] 1) Ad Hoc networking without cellular signal coverage, mainly used for emergency communication in remote emergency situations or when the communication infrastructure is damaged;
[0036] 2) Ad Hoc networking under full cellular signal coverage, when the physical distance between two nodes is relatively close, they can communicate through the Ad Hoc link, thereby balancing the network load and increasing the system capacity;
[0037] 3) Ad Hoc networking under partial cellular signal coverage, nodes act as relays to enable interactive communication between the ad hoc network and the cellular network, thereby expanding network coverage and improving cellular blind...
