A method for managing transmission resources in a SIP-based communication system by a SIP registrar server can include receiving a first number of register requests from a first client from the number of clients, each register request corresponding to one slot in the predetermined first time period; receiving a second number of register requests from a second client of the number of clients, each register request corresponding to one slot in the predetermined first time period, wherein the second number of register requests exceeds the acceptable predetermined number of register requests for the second client, and assigning a number of slots not used by the first client within the predetermined first time period to the second client for sending the register requests which exceed the acceptable predetermined number of register requests for the second client. A system for implementation of the method and an apparatus can be utilized in embodiments of the method and the system.

Method and system for managing transmission resources in a SIP-based communication system

A computer apparatus (e.g. a server) and a method for managing transmission resources in a SIP-based communication system can include use of a SIP registrar server that is adapted to receive register requests from a number of clients connected to the SIP registrar server via a communication network. Each client can be granted a predetermined number of register requests in a predetermined first time period where each register request corresponds to a slot. In the first time period, at least one slot not used by a first client can be lent to a second client. In a second time period, the at least one slot lent to the second client can be reclaimed by the first client or another client. The reclaiming of the lent slot(s) can include making the second client function as a proxy for other clients according to a third party registration process.
