    • The present invention provides a wireless communication network system that maintains uplink control for the mobile terminal in peer-to-peer communication. According to one embodiment of the invention, after determining a reliable direct communication link can be set up between the mobile terminals, the network system transmits information including control commands to the mobile terminals for establishing direct communication. The information includes a burst structure type, with the burst structure containing at least one section for carrying control information intended for the network system. After the direct communication is established, the network system continuously listens to signals communicated between the mobile terminals to receive bursts. The network system demodulates received bursts that are communicated between the two mobile terminals to determine whether a received burst contains control information intended for the network system. If control information intended for the network system is included in a received burst, the network performs a corresponding function. In this way, the uplink control for the mobile terminals can be effectively maintained in peer-to-peer communication.
    • 本发明提供了一种在对等通信中维护移动终端的上行链路控制的无线通信网络系统。 根据本发明的一个实施例,在确定可靠的直接通信链路之后,可以在移动终端之间建立链路,网络系统向移动终端发送包括控制命令的信息,以建立直接通信。 信息包括突发结构类型,突发结构包含至少一个部分,用于承载用于网络系统的控制信息。 在建立直接通信之后,网络系统连续监听在移动终端之间通信的信号以接收突发。 网络系统解调在两个移动终端之间传送的接收突发,以确定接收的突发是否包含针对网络系统的控制信息。 如果在接收到的突发中包含了针对网络系统的控制信息,则网络执行相应的功能。 以这种方式,可以在对等通信中有效地维持移动终端的上行链路控制。
