10. A method for connection management in a network, the method comprising:receiving, by a first network device from a user equipment (UE), a re-establishment request for a first connection of a first protocol layer, the re-establishment request indicating a failure in a UE connection to the network, the first connection being between the UE and a first network device;
determining, by the first network device, whether a context of the UE is available at the first network device or whether the context of the UE is retrievable from a second network device; and
transmitting, by the first network device, a re-establishment response indicating that a re-establishment of the first connection of the first protocol layer is allowed in response to the context of the UE being available at the first network device or being retrievable from the second network device, a context of a second protocol layer of the UE remaining unchanged during re-establishment of the first connection of the first protocol layer, the second protocol layer being a higher layer than the first protocol layer.
