  • Patent number: 9420447
    Abstract: In one embodiment, a wireless mobile User Equipment (UE) device comprises a message generator configured to send a SIP request message via a first IP network and a processor configured to process a SIP response message received from a network node via the first IP network, the processor further configured to process instructions to provide a treatment for at least one message body content of the SIP response message based on a value of a content type indicator independent of at least one of an absence of a content disposition indicator, a content disposition indicator without a value and a content disposition indicator having a value. The treatment, applied by the UE device, may comprise one of: (i) performing an Emergency Services (ES) call effectuated via a CS network and (ii) performing a registration and an ES call effectuated via an IP network.

  • Publication number: 20140204736
    Abstract: If a wireless device does not know how many data contexts can be supported, then the wireless device might attempt to establish more data contexts than are supported. Such attempt would normally be rejected. However, the signalling involved in the attempt to establish another data context and the rejection of that attempt is considered wasteful. Embodiments of the present disclosure allow such waste to be reduced or avoided by signalling to the wireless device when the maximum number of data contexts is reached or when it is about to be reached. Such signalling can occur before any attempt to establish more data contexts than are supported. Thus, wasteful signaling involved with attempting to establish more data contexts can be avoided.

  • Publication number: 20110194505
    Abstract: Methods and apparatus to support voice solutions for data centric terminals are described. An example method includes sending a combined registration request message for at least one evolved packet system service via a first radio access technology, receiving an EPS service registration accept message comprising an indicator that indicates that circuit switched fall back is supported, and when the user equipment has a voice centric setting, reselecting to a second radio access technology.
