transmitting, upon the user equipment performing a handover from the first primary base station to a second primary base station, said information related to said delay tolerance and priority and the handover indicator to the second primary base station, and
in response to the second primary base station providing sufficient network resources for transmitting the low priority MT user data, establishing a radio connection bearer between the second primary base station and the user equipment for initiating delivery of the low priority MT user data from the cloud server.
7 . A method according to claim 1 , wherein said information related to said delay tolerance and priority is stored in a control plane network entity of the cellular network, such as in a mobility management entity (MME).
8 . A method according to claim 1 , wherein a core network element of the cellular network determines the delay tolerance and the priority for the at least one radio connection bearer for transmitting said MT user data.
9 . A method according to claim 1 , wherein said at least one network element in said radio access network determines the delay tolerance and the priority for the at least one radio connection bearer for transmitting said MT user data.
10 . A method according to claim 9 , wherein the delay tolerance and the priority is determined on the basis of deep packet inspection and traffic type determination at the primary base station (MeNB).
11 . A method according to claim 1 , further comprising said user equipment
determining, on the basis of said information obtained from the cloud server, the delay tolerance and the priority for the at least one radio connection bearer for transmitting said MT user data; and
sending the information related to the delay tolerance and the priority for the at least one radio connection bearer to the primary base station upon requesting transmission of said MT user data.
12 . A method according to claim 1 , further comprising
providing the user equipment with information related to delay tolerance and priority for at least one radio connection bearer for transmitting the mobile originated (MO) user data.
13 . An apparatus comprising at least one processor, a memory including computer program code, the memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
obtain information from a cloud server functionally connected to a cellular network that said cloud server comprises mobile terminated (MT) user data to said apparatus; and
obtain information related to delay tolerance and priority for at least one radio connection bearer for receiving said MT user data via a network element of a radio access network of said cellular network.
14 . An apparatus according to claim 13 , wherein said apparatus is configured to receive said MT user data via a primary base station (MeNB) of the radio access network, wherein
reception of said MT user data is delayed, in response to the information related to said delay tolerance and priority indicating that said MT user data has a low priority, until sufficient network resources are released from higher priority data traffic.
15 . An apparatus according to claim 13 , wherein said information related to said delay tolerance and priority further comprises information about expiration time for delivery of said MT user data.
16 . An apparatus according to claim 13 , wherein said information related to said delay tolerance and priority further comprises information related to cell types or cell identities via which the apparatus can receive said MT user data.
17 . A network element of a radio access network configured to
obtain information from a cloud server functionally connected to a cellular network that said cloud server comprises mobile terminated (MT) user data to a user equipment user data; and
obtain information related to delay tolerance and priority for at least one radio connection bearer for transmitting said MT user data to said user equipment.
18 . A network element according to claim 17 , wherein said network element a primary base station (MeNB) for said user equipment, the network element being configured to
delay the transmission of said MT user data, in response to the information related to said delay tolerance and priority indicating that said MT user data has a low priority, until sufficient network resources are released from higher priority data traffic.
19 . A network element according to claim 17 , wherein the network element is configured to
