Supporting continuation of a data session after performance of a circuit switched fallback procedure

摘要

A method of supporting continuation of a data session at a wireless communication device after performance of a circuit switched fallback (CSFB) procedure is provided. The method can include establishing a data session while connected to a first network and determining an initiation of a voice call while the data session is ongoing over the first network. The method can further include participating in a CSFB procedure to transition from the first network to a second network in response to initiation of the voice call. After termination of the voice call, the method can additionally include determining that sufficient resources are not available to the wireless communication device on the second network to support a minimum threshold throughput for the data session. The method can also include reverting to the first network in response to determining that sufficient resources are not available to support the minimum threshold throughput.

1. A method for supporting continuation of a data session at a wireless communication device after performance of a circuit switched fallback (CSFB) procedure, the method comprising:
establishing the data session while connected to a Long Term Evolution (LTE) network; determining an initiation of a voice call while the data session is ongoing over the LTE network; participating in the CSFB procedure to transition from the LTE network to a legacy network in response to determining the initiation of the voice call, wherein the legacy network supports both voice and data communications; continuing the data session over the legacy network; determining that the voice call has terminated; after termination of the voice call, determining whether sufficient resources are available on the legacy network to support a minimum threshold throughput for the data session while the data session is ongoing over the legacy network; and reverting to the LTE network in response to determining that sufficient resources are not available to support the minimum threshold throughput.
