Abstract
Techniques for controlling Session Initiation Protocol (SIP) overload between a sending entity and a receiving entity includes receiving a message at a send buffer at the sending entity and forwarding the message to a receive buffer at the receiving entity if the send buffer is empty of other messages or rejecting the message if the send buffer is not empty of other messages.
Claims17
A method for controlling Session Initiation Protocol (SIP) overload between a sending entity and a receiving entity comprising:
- receiving a message at a send buffer at the sending entity;
- and
- forwarding the message to a receive buffer at the receiving entity if the send buffer is empty of other messages or rejecting the message if the send buffer is not empty of other messages, wherein the message is an INVITE message.
A method for controlling Session Initiation Protocol SIP overload between a sending entity and a receiving entity comprising:
- receiving a message at a send buffer at the sending entity, wherein the message comprises an INVITE or a non-INVITE message;
- and
- if the message is an INVITE, forwarding the INVITE to a receive buffer at the receiving entity if the send buffer is empty of other messages or rejecting the INVITE if the send buffer is not empty of other messages, and
- if the message is a non-INVITE message, forwarding the message to the receive buffer at the receiving entity.
A method for controlling Session Initiation Protocol (SIP) overload between a sending entity and a receiving entity comprising:
- receiving a message at a send buffer at the sending entity;
- and
- forwarding the message to a receive buffer at the receiving entity if the send buffer does not indicate an overload condition or rejecting the message if the send buffer indicates an overload condition,
- wherein the message is an INVITE message,
- wherein the send buffer indicates an overload condition if the send buffer is not empty of other messages.
A system for controlling Session Initiation Protocol (SIP) overload between a sending entity and a receiving entity comprising:
- a send buffer for receiving a message at the sending entity;
- and
- a processor, coupled to the send buffer, wherein the processor is configured to, in response to receiving the message, cause the send buffer to forward the message to a receive buffer at the receiving entity if the send buffer is empty of other messages or rejects the message if the send buffer is not empty of other messages, wherein the message is an INVITE message.
