  • Method to detect a user equipment stuck on a dedicated channel
    Patent number: 7231213
    Abstract: While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel (202). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel (204), and the UE is placed in idle mode (206). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.
