摘要
According to an example aspect of the present invention, there is provided an apparatus comprising a memory configured to store an indication that the apparatus requires reliable and/or low-latency access to a network, and at least one processing core configured to process an access opportunity pattern, received in the apparatus from a network node, the access opportunity pattern comprising access opportunities provided by a subset of a cluster of cells, detectable by the apparatus, and to trigger for the apparatus reliable and/or low-latency access to the network by selecting from the pattern an access opportunity according to the received access opportunity pattern.

This is a continuation of copending U.S. patent application Ser. No. 16/098,458, filed Nov. 2, 2018, which is a national stage entry under 35 U.S.C. 371 of International Patent Application No. PCT/FI2016/050302, filed May 10, 2016, the disclosure of which is incorporated by reference herein in its Entirety.
The present invention relates to management of a communication network, for example to provide low latency service.
Cellular communication involves communication by wireless devices, which may be mobile or stationary devices that need or do not need human interaction, with communication counterparties via cells. Cells may be controlled by base stations or access points, in dependence of the radio access technology, RAT, used.
To establish connectivity via a cell, a wireless device, hereby frequently referred to as user equipment, UE, however, it should be understood that the wireless device is not restricted to any particular type of device, may request access to the network, using an uplink access opportunity. For example, a random access procedure may be employed, wherein the network provides a transmission opportunity for user equipments to transmit toward to network to signal their willingness to engage in communication.

The invention claimed is:1. A method, comprising:storing by user equipment of a communication network an indication that the user equipment requires at least one of reliable or low-latency access to a network; receiving from a network node of the communication network, an access opportunity pattern, the access opportunity pattern comprising access opportunities provided by a subset of a cluster of cells detectable by the user equipment; receiving during an inactive state, a downlink reference signal from a cell as a part of the received access opportunity pattern addressed to apparatuses which require at least one of reliable or low-latency access, the reference signal informing that at least one user equipment requiring the at least one of reliable or low-latency access will receive a downlink page; monitoring, based on the informing, a downlink paging channel in the access opportunity pattern for the downlink page; and triggering at least one of reliable or low-latency access to the network by selecting an access opportunity according to the received access opportunity pattern. 2. The method according to claim 1 , wherein based on the informing the apparatus does not monitor paging occasions that are determined to be at least one of not reliable or not energy access specific. 3. The method according to claim 1 , wherein the downlink reference signal is specific for at least one Ultra-Reliable Low-Latency Communication capable user equipment. 4. The method according to claim 3 , wherein the downlink reference signal is received from at least one access point of more than one access point identified by the user equipment. 5. The method according to claim 4 , wherein the at least one access point is identified by the user equipment based on an availability pattern of the more than one access point. 6. The method according to claim 1 , wherein the downlink reference signal is received after a downlink synchronization signal. 7. The method according to claim 6 , wherein the downlink reference signal is received after at least one downlink synchronization signal in every system frame of 10 ms. 8. The method according to claim 1 , wherein the triggering is based on selecting an access opportunity according to a received access opportunity pattern. 9. An apparatus, comprising:at least one processor; and at least one non-transitory memory including computer program code, wherein the at least one non-transitory memory including the computer program code is configured, with the at least one processor, to cause the apparatus to: store by a user equipment of a communication network an indication that the user equipment requires at least one of reliable or low-latency access to a networks; receive from a network node of the communication network, an access opportunity pattern, the access opportunity pattern comprising access opportunities provided by a subset of a cluster of cells detectable by the user equipment; receive during an inactive state, a downlink reference signal from a cell as a part of the received access opportunity pattern addressed to apparatuses which require at least one of reliable or low-latency access, the reference signal informing that at least one user equipment requiring the at least one of reliable or low-latency access will receive a downlink page; monitor, based on the informing, a downlink paging channel in the access opportunity pattern for the downlink page; and trigger at least one of reliable or low-latency access to the network by selecting an access opportunity according to the received access opportunity pattern. 10. The apparatus according to claim 9 , wherein based on the informing the apparatus does not monitor paging occasions that are determined to be at least one of not reliable or not energy access specific. 11. The apparatus according to claim 9 , wherein the downlink reference signal is specific for at least one Ultra-Reliable Low-Latency Communication capable user equipment. 12. The apparatus according to claim 11 , wherein the downlink reference signal is received from at least one access point of more than one access point identified by the apparatus. 13. The apparatus according to claim 12 , wherein the at least one access point is identified by the apparatus based on an availability pattern of the more than one access point. 14. The apparatus according to claim 9 , wherein the downlink reference signal is received after a downlink synchronization signal. 15. The apparatus according to claim 14 , wherein the downlink reference signal is received after at least one downlink synchronization signal in every system frame of 10 ms.
