Abstract: Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes fetching a context for a device communicating via a first radio access system of a first network based in part on a unique identifier from a second radio access system of a second network.

Abstract: Methods and apparatuses are provided that facilitate avoiding establishment of unnecessary radio bearers in circuit switched fallback (CSFB). A CSFB procedure related to a device can be detected from receiving an extended service request or a forward relocation request, or from determining that an evolved packet system (EPS) is insufficient to handle a circuit switched voice call, and/or the like. Based at least in part on detecting the CSFB, establishment of radio bearers for inactive EPS bearers can be avoided. Where the device is in idle mode before CSFB, avoiding establishment of radio bearers can include avoiding establishment of all data radio bearers for the device.
