Abstract

A network out-of-synchronization state processing method and apparatus, and a network access method and apparatus are provided. The method includes: if a first network device does not receive, in a first time length after the first network device determines that a terminal is in a network out-of-synchronization state, a measurement message reported by a second network device in a signal coverage area of the first network device, instructing at least one second network device in the signal coverage area of the first network device to send paging signaling to the terminal; and setting a network status of the terminal to a detached state if the first network device determines that in a second time length, no second network device in the signal coverage area of the first network device receives a paging response sent by the terminal, and that the terminal is still in the network out-of-synchronization state.

First claim

What is claimed is:

1 . A method, comprising:
when a first network device does not receive, in a first time length after the first network device determines that a terminal is in a network out-of-synchronization state, a measurement message reported by a second network device of a plurality of second network devices, instructing, by the first network device, at least one third network device of the plurality of second network devices to send paging signaling to the terminal, wherein the measurement message is based on an uplink tracking signal of the terminal, and wherein the plurality of second network devices is in a signal coverage area of the first network device; and when the first network device determines that, in a second time length, the plurality of second network devices has not received a paging response from the terminal, and that the terminal is still in the network out-of-synchronization state, setting, by the first network device, a network status of the terminal to a detached state, wherein the paging response is a feedback message sent by the terminal in response to the terminal receiving the paging signaling.

2 . The method according to claim 1 , further comprising:
when the first network device receives, in the first time length after the first network device determines that the terminal is in the network out-of-synchronization state, the measurement message reported by the second network device, determining, by the first network device, that the terminal has restored a connection to a network.

3 . The method according to claim 1 , further comprising:
when the first network device determines that the at least one third network device of the plurality of second network devices has received the paging response in the second time length, setting, by the first network device, the network status of the terminal to an attached state after the terminal accesses a network through a random access process.

4 . The method according to claim 1 , wherein instructing the at least one third network device of the plurality of second network devices to send the paging signaling to the terminal comprises:
instructing, by the first network device, at least one fourth network device of the plurality of second network devices to send the paging signaling to the terminal, wherein the at least one fourth network device is in a first area of the signal coverage area of the first network device; and when the first network device determines that the at least one fourth network device has not received the paging response in a third time length, and that the terminal is still in the network out-of-synchronization state, instructing, by the first network device, at least one fifth network device of the plurality of second network devices to send the paging signaling to the terminal, wherein the at least one fifth network device is in a second area of the signal coverage area of the first network device.

5 . The method according to claim 4 , wherein determining that, in the second time length, the plurality of second network devices has not received the paging response from the terminal, and that the terminal is still in the network out-of-synchronization state comprises:
when the first network device determines that the at least one fifth network device has not received the paging response in a fourth time length, and that the terminal is still in the network out-of-synchronization state, determining, by the first network device, that the plurality of second network devices has not received, in the second time length, the paging response sent by the terminal, and that the terminal is still in the network out-of-synchronization state, wherein the second time length is equal to a sum of the third time length and the fourth time length.

6 . The method according to claim 5 , wherein instructing, by the first network device , the at least one fifth network device to send the paging signaling to the terminal comprises:
when instructing the at least one fourth network device to send the paging signaling to the terminal, starting, by the first network device, a second timer, wherein a second timing time length of the second timer is the third time length; and when the first network device determines that the at least one fourth network device has not received the paging response before the second timer expires, and that the terminal is still in the network out-of-synchronization state, instructing, by the first network device, the at least one fifth network device to send the paging signaling to the terminal.

7 . The method according to claim 6 , wherein setting, by the first network device, the network status of the terminal to the detached state comprises:
when the second timer expires, starting, by the first network device, a third timer, wherein a third timing time length of the third timer is the fourth time length; and when the first network device determines that the at least one fifth network device has not received the paging response before the third timer expires, and that the terminal is still in the network out-of-synchronization state, setting, by the first network device, the network status of the terminal to the detached state.

8 . The method according to claim 4 , wherein a first size of the first area of the signal coverage area of the first network device is less than or equal to a second size of the second area of the signal coverage area of the first network device.

9 . The method according to claim 4 , wherein the third time length is a required maximum time length between a first moment at which the first network device instructs the at least one fourth network device to send the paging signaling to the terminal and a second moment at which the at least one fourth network device attempts to receive the paging response.

10 . The method according to claim 1 , wherein:
the plurality of second network devices in the signal coverage area of the first network device comprises at least one target device; and the at least one target device has received, before a moment at which the first network device determines that the terminal is in the network out-of-synchronization state, the uplink tracking signal sent by the terminal.

11 . The method according to claim 1 , wherein instructing, by the first network device, the at least one third network device of the plurality of second network devices to send the paging signaling to the terminal comprises:
when the first network device determines that the terminal is in the network out-of-synchronization state, starting, by the first network device, a first timer, wherein a first timing time length of the first timer is the first time length; and when the first network device does not receive, before the first timer expires, the measurement message reported by the second network device, instructing, by the first network device, the at least one third network device to send the paging signaling to the terminal.

12 . The method according to claim 1 , wherein determining that the terminal is in the network out-of-synchronization state comprises:
when the first network device does not receive, in M consecutive periods, the measurement message reported by the second network device, or when the first network device does not receive, in a preset time length, the measurement message reported by the second network device, determining, by the first network device, that the terminal is in the network out- of-synchronization state.

13 . A method, comprising:
sending, by a terminal, an uplink message to a first transmission point N consecutive times, wherein the uplink message is uplink data se
