Congestion/overload control method and apparatus

摘要

Embodiments of the present invention provide a congestion/overload control method and apparatus. The method includes: learning, by a gateway device, information about network access time of a User Equipment (UE) or UE group; and rejecting or discarding, by the gateway device, session management request messages of the UE or UEs in the UE group beyond the network access time of the UE or UE group; or discarding, by the gateway device, data of the UE or the UEs in the UE group beyond the network access time of the UE or UE group. Embodiments of the present invention can perform congestion/overload control differentially on the UE or UEs in the group, implement congestion/overload control on the gateway device, avoid congestion/overload caused by a large number of UEs on the gateway device, and improve the efficiency of congestion/overload control.

主权项

1. A congestion/overload control method, comprising:
obtaining, by a gateway device, information about a congestion/overload control parameter or policy of a User Equipment (UE) group, wherein the information about the congestion/overload control parameter or policy of the UE group comprises at least one of the following: a maximum number of bearers or Packet Data Protocol (PDP) contexts of the UE group, and a maximum access rate of the UE group; and rejecting by the gateway device, session management request messages of UEs in the UE group upon the congestion/overload control parameter or policy of the UE group is reached or exceeded, wherein the rejection comprises sending a session management reject message carrying a first time indication information to a mobility management element that instructs the mobility management element to reject access request messages of the UEs.
