Section: 12.2.5.2 Frequency of inclusion
Content: How often the sender includes the load control information is implementation specific. The sender shall ensure that new/updated load control information is propagated to the target receivers within an acceptable delay, such that the purpose of the information (i.e. effective load balancing) is achieved. The sender may include the LCI IE e.g. as follows: - the sender may include Load Control Information towards a peer only when the new/changed value has not already been provided to that peer; - the sender may include the Load Control Information in each and every message (extended with LCI IE) towards the peer; - the sender may include Load Control Information 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 decide to include the Load Control Information only in a subset of the applicable GTP-C messages. The receiver shall be prepared to receive the load control information in any of the GTP-C messages extended with an LCI IE and upon such reception, shall be able act upon the received load control information.
