Abstract
A method of handling lower layer failure when assigning a Paging Early Indication with Paging Subgrouping (PEIPS) subgroup ID is proposed. If a network supports and accepts the use of PEIPS assistance information for a UE, the network can provide to the UE the negotiated PEIPS assistance information containing a new Paging subgroup ID and a new 5G-GUTI in a REGISTRATION ACCEPT message or in a CONFIGURATION UPDATE COMMAND message, and the UE was assigned with an old paging subgroup ID. When lower layer failure occurs, the network may not successfully receive a REGISTRATION COMPLETE message or a CONFIGURATION UPDATE COMPLETE message from the UE. Accordingly, the network needs to use both possible paging subgroup IDs for the UE until one of the paging subgroup IDs is considered invalid.
Claims20
A method, comprising:
- determining, by a network entity, paging early indication with paging subgrouping (PEIPS) is supported for a user equipment (UE) in a wireless communication network, wherein the UE is assigned with an existing 5G-GUTI and an existing paging subgroup ID;
- transmitting a registration accept message or a configuration update command message to the UE, wherein the registration accept message or the configuration update command message comprises a new 5G-GUTI and a new paging subgroup ID;
- and
- paging the UE by considering the existing paging subgroup ID as valid and the new paging subgroup ID as valid when the network entity does not receive a COMPLETE message from the UE in response to the registration accept message or the configuration update command message.
A network entity, comprising:
- a control circuit that determines paging early indication with paging subgrouping (PEIPS) is supported for a user equipment (UE) in a wireless communication network, wherein the UE is assigned with an existing 5G-GUTI and an existing paging subgroup ID;
- a transmitter that transmits a registration accept message or a configuration update command message to the UE, wherein the registration accept message or the configuration update command message comprises a new 5G-GUTI and a new paging subgroup ID;
- and
- a paging handling circuit that pages the UE by considering the existing paging subgroup ID as valid and the new paging subgroup ID as valid when the network entity does not receive a COMPLETE message from the UE in response to the registration accept message or the configuration update command message.
