摘要： A method for assigning new Diameter sessions to policy and charging rules functions (PCRFs) may be performed at a Diameter routing agent including at least one processor. The method includes receiving input regarding central processing unit (CPU) and session utilization of each of a plurality of PCRFs. The method further includes receiving Diameter message traffic requiring processing by one of the PCRFs. The method further includes identifying, from the Diameter message traffic, traffic for new sessions that have not been assigned to one of the PCRFs. The method further includes assigning the new sessions to the PCRFs based on the input regarding the CPU and session utilizations of the PCRFs. The method further includes routing the received Diameter message traffic for the new sessions to the PCRFs assigned to the new sessions.

摘要： The subject matter described herein includes methods, systems, and computer readable media for implementing intelligent PCRF overload control. A method may be performed at a Diameter Routing Agent (DRA) including at least one processor. The method includes receiving an indication of a first overload level for at least a first PCRF of a plurality of PCRFs and determining, from the first overload level, a first routing rule for routing message traffic to the first PCRF. The method further includes receiving message traffic requiring processing by the first PCRF and performing a first action specified by the first routing rule to accept the message traffic, reject the message traffic, or send a response on behalf of the first PCRF.

摘要： Methods, systems, and computer readable media for multi-protocol stateful routing are provided. One method of routing is performed at a multi-protocol stateful router and includes receiving a first message of a client session that is communicated using a first protocol. The method includes obtaining, from the first message, one or more client identifiers, determining a policy server that is assigned to the client session, and storing the one or more client identifiers and a policy server identifier that is associated with the policy server assigned to the client session as a multi-protocol binding record. The method also includes receiving a second message that is communicated using a second protocol that is different from the first protocol, using the multi-protocol binding record to determine that the second message is in the client session, and route the second message to the policy server that is assigned to the client session.

摘要： A Diameter based network that includes nodes and accommodates Diameter communication sessions between nodes establishes a first Diameter communication session between a first node and a second node, and at some point determines that the first Diameter communication session is lost. The first node generates a query using a second Diameter communication session that is a different session than the first Diameter communication session. The first node transmits the query to the second node, where the query includes a session type and key identifiers for the first Diameter communication session. The second node re-establishes the first Diameter communication session with the first node and transmits, in response to the query, an indication that the first Diameter communication session exists.
