Abstract: Embodiments of the present disclosure include a mobility management entity (MME) receives a downlink data notification (DDN) message sent by a serving gateway (SGW), where the DDN message carries an identity of user equipment, and the DDN message is used to instruct the MME to send a paging message to a base station in a tracking area list (TA list) of the user equipment. After enabling an aggregate paging function, the MME determines, according to the DDN message, whether a priority of the user equipment is higher than a preset level. If the priority of the user equipment is higher than the preset level, the MME directly sends the paging message to the base station. The present disclosure is applicable to a paging message sending process.

Abstract: A method, an apparatus, and a system for adjusting a deployment location of a virtual machine in order resolve a problem that an inter-node communication cost has excessively great impact on an adjustment result in an existing solution for adjusting a deployment location of a virtual machine in a cloud computing system, the inter-node communication cost is corrected according to technical solutions provided in the embodiments of the present disclosure. Consequently, not only a corrected inter-node communication cost can exert impact on the result for adjusting a deployment location of a virtual machine, but also communication traffic can play a major role in affecting the adjustment result. Therefore, a more appropriate result for adjusting a deployment location of a virtual machine can be obtained, and bandwidth consumption inside the cloud computing system can be reduced.
