Method and apparatus for managing terminals
In accordance with an example embodiment of the present invention, there is provided an apparatus comprising at least one memory configured to store an identity of a terminal, at least one processing core configured to use a terminal-specific inactivity timer value and to associate the terminal-specific inactivity timer value with the identity to provide terminal- or user-specific inactivity timers to manage state transitions in mobiles.
1 . An apparatus, comprising:
at least one memory configured to store an identity of a terminal;
at least one processing core configured to derive a terminal-specific inactivity timer value and to associate the terminal-specific inactivity timer value with the identity; and
the at least one processing core being further configured to cause the terminal-specific inactivity timer value to be transmitted to the terminal, wherein the apparatus comprises a base station.
2 . An apparatus according to claim 1 , wherein the inactivity timer determines when to transition the terminal from an active state into an idle state, wherein the terminal transitions into the idle state responsive to no information being communicated between the terminal and the apparatus for a time that corresponds to the terminal-specific inactivity timer value.
3 . An apparatus according to claim 1 , wherein the at least one processing core is further configured to cause an instruction to be transmitted to the terminal responsive to expiry of the inactivity timer, wherein the instruction instructs the terminal to transition to the idle state.
4 . An apparatus according to claim 1 , wherein the at least one processing core is further configured to consider the terminal as in idle state responsive to expiry of the inactivity timer without transmitting an instruction to the terminal
5 . An apparatus according to claim 1 , wherein the apparatus is configured to receive a suggested value for the terminal-specific inactivity timer value from the terminal, and wherein at least one processing core is configured to derive the terminal-specific inactivity timer value is at least in part based on the suggested value.
6 . An apparatus according to claim 5 , wherein the apparatus is configured to derive the terminal-specific inactivity timer value based on the suggested value and information stored in the apparatus.
7 . An apparatus according to claim 6 , wherein the information stored in the apparatus comprises at least one of: a historical average of inactivity timer values in a cell controlled by the apparatus, a quality characteristic of a bearer serving the terminal, a terminal category of the terminal, and information received from a core network.
8 . An apparatus according to claim 1 , wherein the apparatus is configured to transmit the terminal-specific inactivity timer value to a target base station apparatus in connection with a handover of the terminal to the target base station apparatus.
9 . A method, comprising:
storing, in a base station, an identity of a terminal;
deriving, in the base station, a terminal-specific inactivity timer value and associating the terminal-specific inactivity timer value with the identity; and
causing the terminal-specific inactivity timer value to be transmitted to the terminal from the base station.
10 . A method according claim 9 , further comprising receiving a suggested value for the terminal-specific inactivity timer value from the terminal, and deriving the terminal-specific inactivity timer value is at least in part based on the suggested value.
11 . A method according to claim 10 , comprising deriving the terminal-specific inactivity timer value based at least in part on the suggested value and stored information.
12 . A method according to claim 11 , wherein the stored information comprises at least one of: a historical average of inactivity timer values in a cell controlled by an apparatus, a quality characteristic of a bearer serving the terminal, a terminal category of the terminal, and information received from a core network.
13 . An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, wherein
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
derive a terminal-specific inactivity timer value candidate for the apparatus, and
transmit the terminal-specific inactivity timer value candidate to a base station apparatus controlling a cell to which the apparatus is attached.
14 . An apparatus according to claim 12 , wherein the terminal-specific inactivity timer value candidate is derived at least in part depending on at least one of:
applications active in the apparatus, application types of applications active in the apparatus, mobility characteristics of the apparatus, a terminal type of the apparatus and cell type of a cell the apparatus is attached to.
15 . An apparatus according to claim 13 , wherein the apparatus is configured to derive an updated terminal-specific inactivity timer value candidate responsive to a change in input information used in the derivation, and to transmit the updated candidate to the base station apparatus.
