Section: 8.129 Serving PLMN Rate Control
Content: Serving PLMN Rate Control may be configured in the Serving PLMN network, to protect serving network, e.g. the MME and the Signalling Radio Bearers in the E-UTRAN, from the load generated by NAS Data PDUs. It defines the maximum number of the NAS Data PDUs which can be transferred by the Serving Network per 6 minute interval. The maximum number of the NAS Data PDUs which can be transferred for both downlink and uplink shall be configured to a value greater than 10. When the value is set to 0, it shall indicate Serving PLMN Rate Control is not applicable to the PDN Connection for the given direction. The Serving PLMN Rate Control shall only apply to the PDN Connection(s) which is set to Control Plane Only. Serving PLMN Rate Control Information is coded as depicted in Figure 8.129-1.
