Cause determination method and apparatus, and cause indication method and apparatus
A method for determining a paging cause is performed by a base station in a Radio Access Network (RAN) notification area (RNA) where a terminal in an inactive state is located. The method includes: receiving communication information from a core network that needs to be sent to the terminal; and on the basis of the communication information, determining a paging cause for paging the terminal. The terminal may include more than one subscriber identity module (SIM) cards.

sending the paging cause to the other base station.
4 . The method according to claim 3 , further comprising: receiving, by the other base station, the paging cause from the anchor base station, and carrying the paging cause in a paging signaling sent to the terminal.
5 . The method according to claim 3 , further comprising:
sending first indication information to the other base station, wherein the first indication information is configured to indicate the other base station to carry the paging cause in a paging signaling sent to the terminal.
6 . The method according to claim 2 , wherein when the base station is the other base station, the method further comprises:
receiving second indication information from the anchor base station; and
determining that the paging cause is carried in a paging signaling sent to the terminal based on the second indication information.
7 . The method according to claim 2 , wherein determining the paging cause for paging the second SIM card based on the communication information comprises:
determining the paging cause based on cause indication information in the communication information.
8 . The method according to claim 7 , wherein when the base station is the anchor base station, the method further comprises:
sending the paging cause to the other base station.
9 . The method according to claim 8 , further comprising: receiving, by the other base station, the paging cause from the anchor base station, and carrying the paging cause in a paging signaling sent to the terminal; or
sending third indication information to the other base station, wherein the third indication information is configured to indicate the other base station to carry the paging cause in a paging signaling sent to the terminal.
10 . The method according to claim 1 , further comprising:
sending a paging signaling to the terminal, wherein the paging cause is carried in the paging signaling.
11 . A non-transitory computer-readable storage medium for storing a computer program, wherein when the computer program is executed by a processor, steps of the method of claim 1 are implemented.
12 . A method for indicating a cause, performed by a core network, the method comprising:
sending communication information that needs to be sent to a second SIM card of a terminal in an inactive state, to a base station in a Radio Access Network (RAN) notification area (RNA) where the terminal is located, wherein the terminal comprises a first SIM card and the second SIM card, and the terminal communicates via the first SIM card;
wherein a type of a signaling in the communication information is configured for the base station to determine a paging cause for paging the second SIM card, and the paging cause is sent by the base station to the terminal; wherein the paging cause is a priority of a service corresponding to paging, the type of the signaling is configured to determine importance of the signaling, the higher the importance, the higher the corresponding priority; wherein the paging cause is used by the terminal to determine whether to respond to the paging via the second SIM card.
13 . The method according to claim 12 , wherein the base station comprises at least one of:
an anchor base station of the terminal in the RNA or an other base station than the anchor base station in the RNA.
14 . The method according to claim 13 , wherein when the base station is the anchor base station, the paging cause determined is sent by the anchor base station to an other base station.
15 . The method according to claim 14 , wherein when the base station is the anchor base station, the method further comprises:
sending fourth indication information to the anchor base station, wherein the fourth indication information is configured to indicate the anchor base station to send the paging cause determined to the other base station.
16 . The method according to claim 12 , comprising:
determining the paging cause based on the communication information, and generating cause indication information based on the paging cause; and
sending the cause indication information to the base station, wherein the cause indication information is configured for the base station to determine the paging cause.
17 . A communication device, comprising:
a processor; and
a memory for storing a computer program;
wherein when the computer program is executed by the processor, the method of claim 12 is implemented.
18 . A non-transitory computer-readable storage medium for storing a computer program, wherein when the computer program is executed by a processor, steps of the method of claim 12 are implemented.
