Mobility management apparatus reselection method and mobility management apparatus

A method for reselecting a mobility management entity, comprising:

• sending, by user equipment (UE), an access request message to a first mobility management entity;
• obtaining, by the first mobility management entity, subscription data of the UE from a subscriber server, wherein the subscription data comprises information about a type of a mobility management entity that the UE may access;
• determining, by the first mobility management entity according to the information about the type of the mobility management entity, the type of the mobility management entity that the UE may access;
• reselecting, by the first mobility management entity, a second mobility management entity according to the type of the mobility management entity that the UE may access;
• and
• forwarding, by the first mobility management entity, the access request message to the second mobility management entity, wherein the access request message is for requesting the second mobility management entity to execute an access request procedure of the UE.
