A radio access node controlling a candidate source cell for a wireless device in a cellular communications system enabling connection reestablishment for the wireless device to a target cell controlled by a target radio access node, comprising: a network interface configured to enable communication between the radio access node and the target radio access node; at least one processor; and memory containing instructions, the at least one processor being arranged to execute said instructions and cause the radio access node to: receive (300, 500), via the network interface, a context fetch request from the target radio access node comprising an identifier of the wireless device; determine (302, 502) whether there is a matching wireless device for the candidate source cell controlled by the radio access node, the matching wireless device being a wireless device having an identifier for the candidate source cell that matches the identifier of the wireless device comprised in the context fetch request; and if there is a matching wireless device, determine (306, 506) a health of a connection between the matching wireless device and the candidate source cell, wherein, the at least one processor is arranged to execute further instructions stored in the memory and cause the radio access node to return a context for the matching wireless device to the target radio access node as a context for the wireless device if the connection between the matching wireless device and the candidate source cell is determined to be unhealthy; and reject the context fetch request if the connection between the matching wireless device and the candidate source cell is determined to be healthy; or the at least one processor is arranged to execute further instructions stored in the memory and cause the radio access node to return, to the target radio access node, a context for the matching wireless device as a candidate context for the wireless device and a health indicator that is indicative of the health of the connection between the matching wireless device and the candidate source cell as determined by the radio access node. a network interface configured to enable communication between the radio access node and the target radio access node; at least one processor; and memory containing instructions, the at least one processor being arranged to execute said instructions and cause the radio access node to: receive (300, 500), via the network interface, a context fetch request from the target radio access node comprising an identifier of the wireless device; determine (302, 502) whether there is a matching wireless device for the candidate source cell controlled by the radio access node, the matching wireless device being a wireless device having an identifier for the candidate source cell that matches the identifier of the wireless device comprised in the context fetch request; and if there is a matching wireless device, determine (306, 506) a health of a connection between the matching wireless device and the candidate source cell, receive (300, 500), via the network interface, a context fetch request from the target radio access node comprising an identifier of the wireless device; determine (302, 502) whether there is a matching wireless device for the candidate source cell controlled by the radio access node, the matching wireless device being a wireless device having an identifier for the candidate source cell that matches the identifier of the wireless device comprised in the context fetch request; and if there is a matching wireless device, determine (306, 506) a health of a connection between the matching wireless device and the candidate source cell, wherein, the at least one processor is arranged to execute further instructions stored in the memory and cause the radio access node to return a context for the matching wireless device to the target radio access node as a context for the wireless device if the connection between the matching wireless device and the candidate source cell is determined to be unhealthy; and reject the context fetch request if the connection between the matching wireless device and the candidate source cell is determined to be healthy; or the at least one processor is arranged to execute further instructions stored in the memory and cause the radio access node to return, to the target radio access node, a context for the matching wireless device as a candidate context for the wireless device and a health indicator that is indicative of the health of the connection between the matching wireless device and the candidate source cell as determined by the radio access node.
