Broadcast Channel Reception in Multi-subscription Multi-standby Communication Devices

A multi-subscription multi-standby communication device, comprising:

• a memory;
• a radio frequency resource;
• and
• a processor coupled to the memory and the radio frequency resource and configured with processor-executable instructions to:
• determine whether the multi-subscription multi-standby communication device is conducting an active communication session on a first network;
• determine whether broadcast channel data is received over a broadcast channel of a second network in response to determining the multi-subscription multi-standby communication device is conducting the active communication session on the first network;
• determine whether a periodicity of a broadcast rate of a broadcast of the broadcast channel data can be calculated in response to determining that the broadcast channel data is received over the broadcast channel;
• calculate the periodicity of the broadcast channel data, based on a difference in arrival times of two or more blocks of receive broadcast channel data, in response to determining that the periodicity of the broadcast can be calculated;
• schedule one or more tune-aways from the first network to the broadcast channel of the second network based on the calculated periodicity of the broadcast;
• perform the one or more tune-aways from the first network to the broadcast channel of the second network.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a multi-subscription multi-standby communication device to perform operations comprising:

• determining whether the multi-subscription multi-standby communication device is conducting an active communication session on a first network;
• determining whether broadcast channel data is received over a broadcast channel of a second network in response to determining the multi-subscription multi-standby communication device is conducting the active communication session on the first network;
• determining whether a periodicity of a broadcast of the broadcast channel data can be calculated in response to determining that the broadcast channel data is received over the broadcast channel;
• calculating the periodicity of the broadcast of the broadcast channel data, based on a difference in arrival times of two or more blocks of received broadcast channel data, in response to determining that the periodicity of the broadcast can be calculated;
• scheduling one or more tune-aways from the first network to the broadcast channel of the second network based on the calculated periodicity of the broadcast;
• and
• performing the one or more tune-aways from the first network to the broadcast channel of the second network.
