  • Patent number: 9980314
    Abstract: The proposed approach contemplates systems and methods configured to transmit signals irregularly (sparsely) over a mobile communication network (carrier) in which reception gaps apply while increasing the likelihood that receivers will receive a signal at least once during a certain time period, called irregular signal period. First, a set of transmission offsets is selected, the transmission offsets defining a relative transmission time in a burst, such that if a burst would be transmitted using the selected transmission offsets, a receiver with any valid reception gap configuration would receive at least one signal in its whole duration. Then, during an irregular signal period, signals are transmitted in a sequence of one or more consecutive bursts using each of the transmission offsets in the selected set at least once, wherein the sequence of bursts may be preceded and/or followed by a period of no signal transmission.

A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.

  • Patent number: 9930716
    Abstract: Apparatus and methods to support IP flow mobility (IFOM) via multiple wireless accesses in a wireless device are disclosed. The wireless device initiates network-based IFOM (NB-IFOM) to establish and manage IP flows. Support for NB-IFOM is negotiated during initial attach procedures to either or both wireless accesses and by using packet data network (PDN) connectivity procedures. The wireless device sends routing rules including priorities to apply to both existing and future IP flows or to future IP flows only. The wireless device requests to move IP flows from a source access to a target access. When a new wireless access is added to an existing PDN connection, an identical IP address for the wireless device is allocated as used for the existing PDN connection. The network establishes a GPRS tunneling protocol (GTP) tunnel for the new wireless access while maintaining a previously established GTP tunnel for the existing wireless access.

  • Patent number: 9894564
    Abstract: In a wireless communication system, a user equipment device (UE) may undertake a circuit-switched fallback (CSFB) process by using or more secondary radio frequency (RF) receive chains to search for candidate circuit-switched (CS) cells, in parallel with using a primary RF receive chain to wait for an extended service request (ESR) response. The UE may send, using a first RF receive chain, an ESR message on a packet-switched (PS) network in response to receiving a CS voice call page on the PS network. The UE may also start an ESR timer upon sending the ESR message, and monitor, using the first RF receive chain, for receipt of an ESR response on the PS network. While monitoring for receipt of the ESR response, the UE may use a second RF receive chain to acquire an initial CS network, and detect whether the ESR timer expires before the ESR response is received.
