RAN paging handling
A second base station receives, from a first base station, a radio access network (RAN) paging message for a wireless device. The RAN paging message comprises a parameter indicating whether the wireless device is allowed to access a non-closed access group (CAG) cell. The second base station sends a second paging message via a cell determined based on the cell being the non-CAG cell and the parameter indicating that the wireless device is allowed to access a non-CAG cell.
1. A method comprising:
receiving, by a second base station from a first base station, a radio access network (RAN) paging message for a wireless device, the RAN paging message comprising a parameter, wherein:
the parameter being a first value indicates that the wireless device is allowed to access a non-closed access group (CAG) cell; and
the parameter being a second value indicates that the wireless device is not allowed to access the non-CAG cell; and
sending a second paging message via a cell determined based on:
the cell being the non-CAG cell; and
the parameter being the first value.
2. The method of claim 1 , wherein the RAN paging message comprises a list of one or more CAG identifiers of the wireless device.
3. The method of claim 2 , further comprising sending another second paging message via another cell determined based on:
a CAG identifier of the another cell being in the list of one or more CAG identifiers of the wireless device.
4. The method of claim 1 , further comprising avoiding sending the second paging message via the cell based on:
the cell being the non-CAG cell; and
the parameter being the second value.
5. The method of claim 1 , wherein the first base station is a last serving base station of the wireless device.
6. The method of claim 1 , wherein the wireless device is in a radio resource control inactive mode.
7. A method comprising:
sending, by a first base station to a second base station, a radio access network (RAN) paging message for a wireless device, the RAN paging message comprising a parameter, wherein:
the parameter being a first value indicates that the wireless device is allowed to access a non-closed access group (CAG) cell; and
the parameter being a second value indicates that the wireless device is not allowed to access the non-CAG cell.
8. The method of claim 7 , wherein the RAN paging message comprises:
a list of one or more CAG identifiers of the wireless device.
9. The method of claim 7 , further comprising receiving, from a network function, a message for the wireless device, wherein the wireless device is in a radio resource control inactive state.
10. The method of claim 9 , wherein the sending the RAN paging message is in response to the receiving the message from the network function.
11. The method of claim 9 , further comprising sending a second paging message for the wireless device based on the receiving the message from the network function.
12. The method of claim 11 , wherein the sending the second paging message is via a cell of the first base station determined based on:
the cell being the non-CAG cell; and
the parameter being the first value.
13. The method of claim 9 , wherein the network function is one or more of:
a user plane function; and
an access and mobility management function.
14. The method of claim 9 , wherein the message is one or more of:
a data packet; and
a signaling message.
15. The method of claim 7 , wherein the first base station is a last serving base station of the wireless device.
16. A method comprising:
receiving, by a base station from a network function, a message comprising a user data packet for a wireless device associated with a parameter, wherein:
the parameter being a first value indicates that the wireless device is allowed to access a non-closed access group (CAG) cell; and
the parameter being a second value indicates that the wireless device is not allowed to access the non-CAG cell; and
sending, by the base station and based on the message, a paging message via a cell determined based on:
the cell being a non-CAG cell; and
the parameter being the first value.
17. The method of claim 16 , wherein the network function is one or more of:
a user plane function; and
an access and mobility management function.
18. The method of claim 16 , wherein the base station is a last serving base station of the wireless device.
19. The method of claim 16 , further comprising avoiding sending the paging message via the cell based on:
the cell being the non-CAG cell; and
the parameter being the second value.
20. The method of claim 16 , further comprising sending another paging message via another cell determined based on:
a CAG identifier of the another cell being in a list of one or more CAG identifiers of the wireless device.
