Problems solved by technology

[0052] Option 3 has the problem that during the sleep time of the eDRX cycle, the UE will miss the SI change notification sent with one or more paging messages
[0053] The fourth option is a viable solution, but when the configured BCCH modification period is short and the eDRX period exceeds this period, the time to trigger a SIB read may be shortened unnecessarily

Embodiment Construction

[0118] Hereinafter, some exemplary embodiments of the present invention are described in detail with reference to the accompanying drawings, wherein features of the exemplary embodiments may be freely combined with each other unless otherwise described. It should be expressly understood, however, that the description of certain embodiments has been given by way of example only, and it is in no way intended to be construed as limiting the invention to the disclosed details.

[0119] Furthermore, it should be understood that an apparatus is configured to perform a corresponding method, although in some cases only an apparatus or only a method is described.

[0120] In order to avoid the problem of SI updates with long I-eDRX cycles and minimized UE power consumption with the proposed solution as described above, some embodiments of the invention provide a modification to the procedure of option 3, where paging is Used for SI update indication.

[0121] That is to say, the MME i...
