Section: 12.3.5.2 Frequency of inclusion
Content: How often or when the sender includes the overload control information is implementation specific. The sender shall ensure that new/updated overload control information is propagated to the target receivers with an acceptable delay, such that the purpose of the information, (i.e. the effective overload control protection) is achieved. The following are some of the potential approaches the sender may implement for including the OCI IE: - the sender may include OCI IE towards a receiver only when the new/changed value has not already been provided to the given receiver; - the sender may include the OCI IE in a subset of the messages towards the receiver; - the sender may include the OCI IE periodically, i.e. include the information during a first period then cease to do so during a second period. The sender may also implement a combination of one or more of the above approaches. Besides, the sender may also include the OCI IE only in a subset of the applicable GTP-C messages. The receiver shall be prepared to receive the overload control information received in any of the GTP-C messages extended with an OCI IE and upon such reception, shall be able act upon the received information.
