Abstract
A method for operating a mobile entity in a mobile communications network having at least one slice is provided. The slice of the mobile communication to which the mobile entity intends to connect is determined. Additionally, whether a relationship can be identified in the mobile entity is determined. The relationship indicates whether the slice to which the mobile entity intends to connect is related to an access point of the slice. A request message is then transmitted to a radio access network (RAN) of the mobile communications network that includes the identified relationship.
Claims29
A method for operating a mobile entity in a mobile communications network that supports at least one slice, the method implemented by the mobile entity and comprising:
- sending a request message to a radio access network (RAN) entity in the mobile communications network, the request message comprising a first network slice identifier identifying a slice to which the mobile entity intends to connect;
- receiving a response to the request message, wherein the response comprises a second network slice identifier the mobile entity is allowed to connect;
- and
- transmitting a connection request comprising the second network slice identifier and a related access point name when connecting to a slice of the mobile communication network.
A mobile entity for operating in a mobile communications network comprising at least one slice, the mobile entity comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the mobile entity is operative to:
- send a request message to a radio access network (RAN) entity in the mobile communications network, the request message comprising a first network slice identifier identifying a slice to which the mobile entity intends to connect;
- receive a response to the request message, wherein the response comprises a second network slice identifier the mobile entity is allowed to connect;
- and
- transmit a connection request comprising the second network slice identifier and a related access point name when connecting to a slice of the mobile communication network.
A method for operating a network entity in a mobile communications network supporting at least one slice, the method implemented by the network entity and comprising:
- receiving, from a mobile entity, a request message in the mobile communications network, the request message comprising a first network slice identifier identifying a slice to which the mobile entity intends to connect;
- sending, to the mobile entity, a response to the request message, wherein the response comprises a second network slice identifier the mobile entity is allowed to connect, the second network slice identifier selected based on subscription information of the mobile entity;
- and
- receiving, from the mobile entity, a connection request message to establish a connection using the second network slice identifier and a related access point name when connecting to a slice of the mobile communication network.
A network entity configured to control a non-access stratum signaling of a mobile entity in a mobile communications network comprising at least one slice, the network entity comprising:
- processing circuitry;
- and
- memory containing instructions executable by the processing circuitry whereby the network entity is operative to:
- receive, from the mobile entity, a request message in the mobile communications network, the request message comprising a first network slice identifier identifying a slice to which the mobile entity intends to connect;
- send, to the mobile entity, a response to the request message, wherein the response comprises a second network slice identifier the mobile entity is allowed to connect, the second network identity selected based on subscription information of the mobile entity;
- and
- receive, from the mobile entity, a connection request message to establish a connection using the second network slice identifier and a related access point name when connecting to a slice of the mobile communication network.
