Abstract
The invention describes a method for detecting an inability to serve a UE in the selected serving node due to mismatch between the UE's DCN-related indication and the UE's DCN-related subscription and/or the UE's capabilities and/or due to serving node congestion. The method allows to update the UE's DCN configuration information, so that the UE can be assigned to an appropriate DCN during the next RRC/NAS request procedure.
Claims11
A communication method for a mobile terminal, comprising:
- transmitting a Non-Access Stratum (NAS) request message comprising information of a first network slice with no information of a second network slice, to a core network node via an access network node;
- and
- receiving a NAS accept message comprising information of the second network slice to be used by the mobile terminal, from the core network node, in response to a transmission of the NAS request message comprising the information of the first network slice with no information of the second network slice;
- transmitting another NAS message comprising the information of the second network slice, to the core network node,
- wherein a value of the information of the second network slice is determined by the core network node.
A mobile terminal, comprising:
- a transmitter configured to transmit a Non-Access Stratum (NAS) request message comprising information of a first network slice with no information of a second network slice, to a core network node via an access network node;
- and
- a receiver configured to receive a NAS accept message comprising information of the second network slice to be used by the mobile terminal, from the core network node, in response to a transmission of the NAS request message comprising the information of the first network slice with no information of the second network slice,
- wherein the transmitter is further configured to transmit another NAS message comprising the information of the second network slice, to the core network node, and
- wherein a value of the information of the second network slice is determined by the core network node.
A non-transitory computer readable recording medium storing a computer program comprising computer implementable instructions, the computer program causing a programmable communications device to perform a communication method for a mobile terminal, the method comprising:
- transmitting a Non-Access Stratum (NAS) request message comprising information of a first network slice with no information of a second network slice, to a core network node via an access network node;
- and
- receiving a NAS accept message comprising information of the second network slice to be used by the mobile terminal, from the core network node, in response to a transmission of the NAS request message comprising the information of the first network slice with no information of the second network slice;
- transmitting another NAS message comprising the information of the second network slice, to the core network node,
- wherein a value of the information of the second network slice is determined by the core network node.
