Patent Issued for Broadband Service Nesting Processing Method and Device, and Service Application Server

July 8, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventor Chen, Fei (Nanjing, CN), filed on December 10, 2012, was published online on June 24, 2014.

The patent's assignee for patent number 8761057 is Huawei Technologies Co., Ltd. (Shenzhen, CN).

News editors obtained the following quote from the background information supplied by the inventors: "Nesting of multiple broadband services exists in an IP multimedia system (hereafter referred to as IMS), especially when a user subscribes to SIP Terminal call (hereafter referred to as STC) services, such as call hold and call transfer. Terminating call services of that type are processed by a terminating call service server.

"For example, in the case of a conference call, a conference service server routes calls of participants A, B, and C, where user B subscribes to a call hold service in terminating call services. When the user B receives another call, user B holds the original call and answers the new incoming call. A terminating call service server of B identifies that B initiates a call hold operation and needs to play a hold tone to a caller leg of B. In a site where B is located, all participants (excluding B) hear the hold tone, which disturbs the normal order of the site.

"In another case, a user subscribes to a wake-up call service. At the wake-up time specified by user A, a wake-up call service server delivers a route to a number of user A. In normal conditions, a terminal equipment of user A rings, achieving the purpose of wake-up. In this case, if user A subscribes to a terminating call service and a service such as call forwarding unconditional or one number link you, an incoming wake-up call is transferred to another forwarded-to number, and the purpose of waking up A through an alarm tone cannot be achieved.

"The preceding current services (conference call and wake-up call services) cannot be normally performed due to impacts of subsequent terminating call services (call hold and call transfer). Situations where the preceding current services cannot be normally performed due to mutual impacts between the current services and the subsequent terminating call services are collectively referred to as broadband service nesting, and no effective technical solution is provided in the prior art."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventor's summary information for this patent: "Embodiments of the present invention provide a broadband service nesting processing method and device, and a service application server to effectively solve broadband service nesting problems.

"An embodiment of the present invention provides a broadband service nesting processing method, including: receiving a service request message sent to a user equipment, and obtaining a service identity of a current service carried in the service request message; determining that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service; and evading the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity.

"An embodiment of the present invention provides another broadband service nesting processing method, including: generating, by a service application server, a service request message sent to a user equipment, where the service request message carries a service identity of a current service used to evade service nesting; and sending, by the service application server, the service request message to a broadband service nesting processing device, so that the broadband service nesting processing device determines that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service, and evades the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity.

"The present invention further provides a broadband service nesting processing device, including: a first receiving module, configured to receive a service request message sent to a user equipment, where an extended header field of the service request message carries a service identity of a current service; a nesting determining module, configured to determine that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service; and a service processing module, configured to evade the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity.

"The present invention further provides a service application server, including:

"a service request generating module, configured to generate a service request message sent to a user equipment, where the service request message carries a service identity of a current service used to evade service nesting; and

"a sending module, configured to send the service request message to a broadband service nesting processing device, so that the broadband service nesting processing device determines that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service, and evades the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity.

"The broadband service nesting processing method and device, and service application server provided in the present invention perform nesting evading processing for a subsequent terminating call service when determining, based on a service identity of the current service carried in an extended header field of a service request message, that service nesting is formed between a current service and the terminating call service, effectively solving service nesting problems."
