Abstract

Embodiments of the present invention, relating to the communications field, disclose a paging optimization method, apparatus, and system, so as to ensure that a terminal normally receives a paging message sent by a system. A specific solution carried by an access network node is: receiving a first paging message sent by a core network node, where the first paging message is used to page a terminal; in response to the first paging message, determining a transmission parameter according to channel loss information of the terminal; and sending control information with enhanced coverage to the terminal according to the transmission parameter, wherein the control information with enhanced coverage is used to schedule a second paging message with enhanced coverage. The present invention is used in a paging optimization process.

First claim

What is claimed is:

1. A paging method performed by an access network node, the method comprising:
receiving a first paging message sent by a core network node, wherein the first paging message instructs the access network node to page a terminal and comprises channel loss information that is a range index of a value of a channel loss between the access network node and the terminal;
in response to the first paging message, determining a number of repeating times for transmitting control information to the terminal, wherein determining the number is based on the range index and a correspondence relationship between the range index and the number of repeating times, the correspondence relationship being pre-stored in the access network node;
repeatedly transmitting for the number of repeating times the control information to the terminal, wherein the control information is for scheduling a second paging message; and
sending the second paging message to the terminal as scheduled by the control information.

2. The paging method according to claim 1 , wherein before receiving the first paging message sent by the core network node, the method further comprises:
receiving the channel loss information sent by the terminal; and
sending the channel loss information of the terminal to the core network node.

3. An access network node comprising:
a receiver receiving a first paging message sent by a core network node, wherein the first paging message instructs the access network node to page a terminal and comprises channel loss information that is a range index of a value of a channel loss between the access network node and the terminal;
a processor determining a number of repeating times for transmitting control information to the terminal in response to the first paging message, wherein determining the number is based on the range index and a correspondence relationship between the range index and the number of repeating times, the correspondence relationship being pre-stored in the access network node; and
a transmitter repeatedly transmitting for the number of repeating times the control information to the terminal, wherein the control information is for scheduling a second paging message, and sending the second paging message to the terminal as scheduled by the control information.

4. The access network node according to claim 3 , wherein:
the receiver receives the channel loss information set by the terminal; and
the transmitter sends the channel loss information of the terminal to the core network node.

5. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to perform operations comprising:
receiving, a first paging message sent by a core network node, wherein the first paging message instructs a access network node to page a terminal and comprises channel loss information that is a range index of a value of a channel loss between the access network node and the terminal;
in response to the first paging message, determining a number of repeating times for transmitting control information to the terminal, wherein determining the number is based on the range index and a correspondence relationship between the range index and the number of repeating times, the correspondence relationship being pre-stored in the access network node;
repeatedly transmitting for the number of repeating times the control information to the terminal, wherein the control information is for scheduling a second paging message; and
sending the second paging message to the terminal as scheduled by the control information.
