Abstract: When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

Abstract: A chip is coupled to a device. The device stores at least one configuration parameter for configuring an access to an Internet type network. According to the invention, the chip stores data relating to at least two subscriptions. The method comprises the following steps. The chip de-activates a first subscription. The chip activates a second subscription. The second subscription is distinct from the first subscription, as a previously active subscription. The second subscription is a currently active subscription. The chip detects whether the device does or does not read a currently active subscription. Only if the device reads a currently active subscription, then the chip detects whether at least one configuration parameter does or does not allow accessing an Internet type network. Only if at least one configuration parameter does not allow accessing an Internet type network, then the chip ascertains that at least one configuration parameter is corrupted.

Abstract: A method of routing communications from a mobile device to a target device. A non-whispered speech target device routing list and a whispered speech target device routing list are stored at a memory that is accessible by the mobile device. The mobile device identifies speech characteristics associated with a speech input and further determines whether the speech input corresponds to a whispered speech based on the speech characteristics. When it is determined that the speech input corresponds to a whispered speech, the mobile device routes communications corresponding to the speech input to each target device included in the whispered speech target device routing list. When it is determined that the speech input does not correspond to a whispered speech, the mobile device either routes or refrains from routing communications corresponding to the speech input to each target device included in the non-whispered speech target device routing list.

Abstract: A method and device for monitoring paging signals are provided. A method of DRX cycle extension for a mobile terminal in an IDLE mode is provided. The method is used to extend the current DRX cycle. A longer paging cycle is designed by extending a UE-specific paging cycle or introducing a new coefficient in system information. A method for extending the SFN is proposed in the invention. A boundary and a serial number of the SFN in the longer wrap around are indicated by the SI. To avoid a situation in which the high paging load occurs in certain paging frames or subframes, the UE_ID is extended in the invention. The proposed mechanism can flexibly adjust the paging cycle and the SFN extension to meet the actual requirements. The long DRX cycle can save a lot of power consumption of the mobile terminals in the IDLE mode.
