Patent ID: 8620314

Claim:
A method of determining a connection quality between a wireless device and a wireless communications network, comprising: receiving a plurality of communications messages as recorded by the wireless device, wherein the plurality of communications messages comprise standard communications messages transmitted from, and received by, the wireless device via the wireless communication network, and each individual standard communications message is not directly associated with connection-quality-related event mechanisms; and generating a connection quality record comprising a connection quality characteristic based on a detection of a predetermined sequence of communications messages that define the connection quality characteristic within the plurality of communications messages, wherein the connection quality record is generated against a set of predetermined parameters; wherein the plurality of communications messages comprise messages in a Universal Mobile Telephone System (â€œUMTSâ€) protocol, and the connection quality characteristic comprises a number of access failures determined by a difference between a sum of access successes and a sum of access attempts, wherein the sum of access attempts includes: a sum of the number of unique connection request messages of a first type comprising one of an originating call, a terminating call, or an emergency call, and a sum of the number of unique connection request messages of a second type followed by either a service request signaling of a first type, or a setup non-access stratum (NAS) signaling message; and the sum of access successes includes: a sum of a number of alert signal messages associated with ones of the first type and the second type of the unique connection request messages, respectively, a sum of a number of connect signaling messages associated with ones of the first type and the second type of the unique connection request messages, respectively, without an associated alert signal message, and a sum of a number of connect acknowledge signaling messages associated with ones of the first type and the second type of the unique connection request messages, respectively, without the associated alert signaling message or an associated connect signaling message.
