Abstract
A paging method, a paging device, and system are described. A mobility management network element (MME) obtains location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network, where the UE already accesses the non-3GPP network. The MME receives a downlink data notification message, where the downlink data notification message carries an identifier of the UE. The MME pages the UE according to the location information of the UE in the non-3GPP network. In some implementations, a paging range may be determined according to the location information of the UE in the non-3GPP network, and a paging message does not need to be sent to all base stations in a registration area of the UE.
Claims14
A paging method, comprising:
- obtaining, by a mobility management network element, location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network;
- determining, by the mobility management network element, that the UE has accessed the non-3GPP network and should be notified over the non-3GPP network to establish a connection with a 3GPP network according to the location information of the UE in the non-3GPP network, wherein an attach procedure on the 3GPP network and an attach procedure on the non-3GPP network have been completed by the UE, and the UE is in an idle state on the 3GPP network;
- sending, by the mobility management network element, a notification message including an access identifier of the 3GPP network to the UE by using a non-3GPP network access gateway;
- and
- sending, by the mobility management network element, a first paging message to a base station in the 3GPP network, wherein the first paging message includes the location information of the UE in the non-3GPP network for the base station to determine whether to send a second paging message to the UE, and the second paging message does not include the location information of the UE in the non-3GPP network to the UE.
An apparatus in a mobility management network element for executing a paging method, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to:
- obtaining, by a mobility management network element, location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network;
- determine that the UE has accessed the non-3GPP network and should be notified over the non-3GPP network to establish a connection with a 3GPP network according to the location information of the UE in the non-3GPP network, wherein an attach procedure on the 3GPP network and an attach procedure on the non-3GPP network have been completed by the UE, and the UE is in an idle state on the 3GPP network;
- send a notification message including an access identifier of the 3GPP network to the UE by using a non-3GPP network access gateway;
- and
- send a first paging message to a base station in the 3GPP network, wherein the first paging message includes the location information of the UE in the non-3GPP network for the base station to determine whether to send a second paging message to the UE, and the second paging message does not include the location information of the UE in the non-3GPP network to the UE.
