Delaying traffic channel assignment based on received signal quality and wireless communication device motion
First Claim

1. A method comprising:
- a radio access network (RAN) obtaining a signal quality measurement that indicates a strength at which a wireless communication device (WCD) receives signals from the RAN;
the RAN determining that a channel assignment message is to be transmitted to the WCD;
in response to determining that the channel assignment message is to be transmitted to the WCD, the RAN further determining whether (i) the signal quality measurement does not meet a given signal quality threshold, and (ii) the WCD is substantially in motion; and
in response to the determining that (i) the signal quality measurement does not meet the given signal quality threshold, and (ii) the WCD is substantially in motion, the RAN waiting a period of time before transmitting the channel assignment message to the WCD, wherein the period of time is between 10 milliseconds and 10 seconds.

Abstract
A radio access network (RAN) may assign a wireless channel from a wireless coverage area to a wireless communication device (WCD) by transmitting a channel assignment message to the WCD. In situations where transmitting the channel assignment message is likely to cause the channel assignment message to be lost or damaged, the RAN may delay transmission of the channel assignment message or refrain from transmitting the channel assignment message. For example, if the WCD is receiving signals from the RAN with a poor signal strength, the RAN may wait until the WCD has had an opportunity to improve its coverage before transmitting the channel assignment message.

10. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, if executed by a radio access network (RAN), cause the RAN to perform operations comprising:
-
obtaining a signal quality measurement that indicates a strength at which a wireless communication device (WCD) receives signals from the RAN; determining that a channel assignment message is to be transmitted to the WCD; in response to determining that the channel assignment message is to be transmitted to the WCD, further determining whether (i) the signal quality measurement does not meet a given signal quality threshold, and (ii) the WCD is substantially in motion; and in response to the determining that (i) the signal quality measurement does not meet the given signal quality threshold, and (ii) the WCD is substantially in motion, waiting a period of time before transmitting the channel assignment message to the WCD, wherein the period of time is between 10 milliseconds and 10 seconds. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method comprising:
-
a radio access network (RAN) obtaining a signal quality measurement that indicates a strength at which a wireless communication device (WCD) receives signals from the RAN; the RAN determining that a channel assignment message is to be transmitted to the WCD; in response to determining that the channel assignment message is to be transmitted to the WCD, the RAN further determining whether (i) the signal quality measurement does not meet a given signal quality threshold, and (ii) the WCD is substantially in motion; in response to the determining that (i) the signal quality measurement does not meet the given signal quality threshold, and (ii) the WCD is substantially in motion, the RAN waiting a period of time, wherein the period of time is between 10 milliseconds and 10 seconds; and after the period of time has elapsed, the RAN (i) obtaining a second signal quality measurement that indicates a second strength at which the WCD receives signals from the RAN, (ii) if the second signal quality measurement meets the given signal quality threshold, transmitting the channel assignment message to the WCD, and (iii) if the second signal quality measurement does not meet the given signal quality threshold, refraining from transmitting the channel assignment message to the WCD.
