  • Patent number: 10003418
    Abstract: A testing apparatus obtains user equipment (UE) parametric measurements with unknown and/or unavailable authentication and security information. The testing apparatus may obtain uplink and downlink parameters of a wireless device after the wireless device initiates registration while an associated timer is activated, enabling the testing apparatus to obtain additional measurement information without security information about the tested wireless device. The apparatus may also measure the UE's transmitted power level prior to the initiation of the authentication procedure. The testing apparatus may determine if a wireless device is to be tested at another frequency pair. If so, the testing apparatus redirects the wireless device to a radio resource at the other frequency pair. The testing apparatus then obtains uplink and downlink parameters for the wireless device by performing pre-registration and intra-registration measurements at the other frequency pair.

  • Publication number: 20070004417
    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.
