  • Publication number: 20130039287
    Abstract: A method, mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC) connection. In some examples, the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples, RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101), in response to the connection suspend command message, suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.

  • Publication number: 20130039339
    Abstract: In order to re-establish a suspended RRC connection, the mobile device (101) in one example sends a connection re-establishment request message to the RAN (102) to have the suspended RRC connection re-established. The RAN node may need to attempt to retrieve the RRC connection data (either from memory or if from another network element if stored elsewhere/if the RRC connection was suspended by another RAN node) and verifies whether the RRC connection is valid. When verified, the mobile device (101) receives, in response to the message, a connection re-establishment command message from the RAN (102). In response to the message, the mobile device (101) re-establishes the RRC connection with the RAN (102), using the stored RRC connection information, and sends a connection re-establishment complete message to the RAN (102). The mobile device (101) and RAN (102) may then resume user plane data communication with each other.

  • Publication number: 20120302196
    Abstract: A method implemented in a UE. NAS signaling is initiated or performed for an emergency call in order to establish a connection between the UE and one of a plurality of core networks (CNs). In a non-limiting example, the NAS signaling is initiated or performed after the ending of a prior established connection or emergency call. A determination is made whether the UE is already attached for emergency bearer services. Responsive to the UE being already attached for emergency bearer services, a NAS layer of a protocol stack of the UE causes transmission of a UE identification (ID) when requesting a radio resource control (RRC) connection for further NAS signaling. The UE ID includes data which can be used to determine to which CN of the plurality of CNs the connection should be directed.

  • Publication number: 20120120815
    Abstract: A wireless network, such as an LTE (“Long-Term Evolution”) network, may be configured to monitor a communications interface to set an inactivity timer that, in turn, sets the operating mode of a communications interface. The operating mode may comprise a time-domain reception pattern of the wireless device. A wireless device may monitor a communications interface that includes at least a first logical channel (for example for a first application) and a second logical channel (for example for a second application). Based on monitoring the communications interface, a first activity state for the first logical channel may be determined. Also, based on monitoring the communications interface, a second activity state (e.g., an activity status) for the second logical channel may be determined. An inactivity timer used by the communications interface may be set to a first value or a second value based on the first and second activity states.
