Abstract: In order to facilitate communication in a wireless network, an accessibility issue in the wireless network may be detected. For example, if an electronic device is near the boundary between two adjacent cells in the cellular-telephone network, the signal power of signals from a current cell or connection may decrease. Concurrently, the maximum transmit power of the electronic device may be constrained by a thermal limit of the electronic device. When this occurs, the connection may be lost unless remedial action is taken. Therefore, in response to this condition, the electronic device may temporarily increase the maximum transmit power to allow the electronic device to communicate with the cellular-telephone network so that the connection may be transitioned to another cell or connection. In this way, the communication technique may restore the communication performance and avoid a dropped call, which will improve the user experience and customer satisfaction.

Abstract translation: 为了促进无线网络中的通信，可以检测无线网络中的可访问性问题。 例如，如果电子设备在蜂窝电话网络中的两个相邻小区之间的边界附近，则来自当前小区或连接的信号的信号功率可能减小。 同时，电子设备的最大发射功率可能受到电子设备的热限制的限制。 发生这种情况时，连接可能会丢失，除非采取补救措施。 因此，响应于这种情况，电子设备可以临时增加最大发射功率，以允许电子设备与蜂窝电话网络通信，使得连接可以转换到另一小区或连接。 以这种方式，通信技术可以恢复通信性能并避免掉话，这将提高用户体验和客户满意度。
