Abstract
Systems and methods for network slice continuity in handover of a communication network are provided. In some embodiments, a User Equipment (UE) is configured to receive, from a network node on a first cell, a first message comprising an indication of at least one cell that supports a particular network slice and engage in a handover operation based on the indication comprised in the received first message. In some embodiments, a network node is configured to sending, to a UE on a first cell, a first message comprising an identification of at least one cell that supports a particular network slice.
Claims26
A method performed by a User Equipment (UE) comprising:
- sending, to a network node on a first cell, a measurement report only about at least one cell other than the first cell that supports a particular network slice, wherein the particular network slice is in use by the UE on the first cell;
- receiving, from the network node, a first message comprising an indication of the at least one cell;
- and
- engaging in a handover operation based on the indication comprised in the received first message.
A method performed by a network node, comprising:
- receiving, from a User Equipment (UE) on a first cell, a measurement report only about at least one cell other than the first cell that supports a particular network slice, wherein the particular network slice is in use by the UE on the first cell;
- and
- sending, to the UE, a first message comprising an identification of the at least one cell.
A User Equipment (UE) comprising:
- one or more transmitters;
- one or more receivers;
- and
- processing circuitry associated with the one or more transmitters and the one or more receivers, the processing circuitry configured to cause the UE to perform operations comprising:
- sending, to a network node on a first cell, a measurement report only about at least one cell other than the first cell that supports a particular network slice, wherein the particular network slice is in use by the UE on the first cell;
- receive, from the network node, a first message comprising an indication of the at least one cell;
- and
- engage in a handover operation based on the indication comprised in the received first message.
A network node comprising processing circuitry configured to cause the network node to perform operations, comprising:
- receiving, from a User Equipment (UE) on a first cell, a measurement report only about at least one cell other than the first cell that supports a particular network slice, wherein the particular network slice is in use by the UE on the first cell;
- and
- sending, to the UE, a first message comprising an identification of the at least one cell.
