Problems solved by technology

However, this scheme assumes that the SIP session and the SIP call are identical, which is not the case for serialized applications
Therefore, this solution still produces a great waste of resources

Embodiment Construction

[0013] first reference figure 1 , illustrates an exemplary communication system 100 in conjunction with which the overload choke described herein may be implemented. More specifically, the communication system 100 may include a plurality of communication devices 108, 112 that communicate with each other using a number of possibly different forms of communication. In some embodiments, the communication system 100 includes two or more regions or enterprises 104a, 104b owned and operated by two different entities (eg, two different companies, businesses, etc.).

[0014] One or both enterprises 104a, 104b may include one or more communication devices or endpoints 108 that allow users in the enterprise to communicate with other users in the enterprise or with users outside the enterprise to communicate. In particular, the communication device 108 may be connected to a communication network 136 that facilitates communication with other non-enterprise communication devices or endpo...

Abstract

The invention discloses phase based prioritization of IMS signaling messages for overload throttling. Systems and methods for providing overload protection in a communications system are provided. More particularly, an importance or priority rating of a message received at a communication server is determined. If the communications system is in an overload state, and if the importance rating of the received message is not sufficiently high, overload protection is applied. Overload protection can include denying service to a requested or in process communications system associated with the message.

Description

technical field [0001] Methods and systems are provided for prioritization of IMS signaling messages using message phases. Background technique [0002] Establishing a communication session in a modern Internet Protocol (IP) based communication system typically involves sending, receiving and processing a variety of signaling messages by a number of signaling entities. For example, in a Session Initiation Protocol (SIP) network, establishing a session between two SIP endpoints A and B typically requires sending an INVITE message from endpoint A to server S1, which forwards the INVITE message to server S2 or endpoint B, or Create another SIP signaling message. S2 will have the same options, possibly bringing in server S3, or looping back to S1, etc. Communication systems typically employ recovery mechanisms such as selecting an alternate route, or indicating to the user that the call cannot be completed. [0003] The time it takes to complete the setup process successfully...
