Abstract
Abstract In a communication system 100, failures can be determined without field testing in the following manner. For each transmission, a communication unit 104 determines the signal quality of the transmission. When the signal quality of the transmission is unfavorable, the communication unit 104 determines its location within the communication system 100 and the time the transmission was transmitted. Having stored this information, the communication unit 104 transmits it to a communication resource allocator 101. Upon receiving this information, the communication resource allocator 101 determines a cause for the unfavorable signal quality.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
200 words
In a communication system that includes a plurality of communication units, a limited number of communication resources that are transceived via broadcast units, and a communication resource allocator, a method for identifying low signal quality communications, the method comprises the steps of: a) monitoring, by a communication unit of the plurality of communication units, signal quality of transceived communications to and from the communication unit; b) determining, by the communication unit, whether any of the transceived communications have an unfavorable signal quality level to produce an unfavorable transceived communication; c) when the unfavorable transceived communication is determined, determining, by the communication unit, location of the communication unit and transmitting time of day, including the date of the unfavorable transceived communication; d) storing, by the communication unit, the location of the communication unit, the transmitting time of day, including the date, and signal quality level of the unfavorable transceived communication to produce stored signal quality information; e) transmitting, by the communication unit, the stored signal quality information to the communication resource allocator; and f) determining, by the communication resource allocator, a cause for the unfavorable signal quality level of the transceived communication, such that the low signal quality communications are identified.

Claim 11
Dependent Claim
138 words
In a communication system that includes a plurality of communication units, a limited number of communication resources that are transceived via broadcast units, and a communication resource allocator, a method for identifying low signal quality communications, the method comprises the steps of: a) receiving, by the communication resource allocator, signal quality information of transceived communications from a communication unit of the plurality of communication units, wherein the signal quality information includes location of the communication unit when a transceived communication having an unfavorable signal quality occurred and transmitting time of day, including the date, of the transceived communication; b) storing, by the communication resource allocator, the signal quality information in a database; and c) determining, by the communication resource allocator, a cause for the unfavorable signal quality level of the transceived communication based on the signal quality information.
Claim 12
Dependent Claim
138 words
In a communication system that includes a plurality of communication units, a limited number of communication resources that are transceived via broadcast units, and a communication resource allocator, a method for identifying low signal quality communications, the method comprises the steps of: a) receiving, by the communication resource allocator, signal quality information of transceived communications from a communication unit of the plurality of communication units, wherein the signal quality information includes location of the communication unit when a transceived communication having an unfavorable signal quality occurred and transmitting time of day, including the date, of the transceived communication; b) storing, by the communication resource allocator, the signal quality information in a database; and c) determining, by the communication resource allocator, a cause for the unfavorable signal quality level of the transceived communication based on the signal quality information.
