Claim of US Patent No. 9,137,674

1. A method for transmitting a startup phase indicator, the method comprising:
judging, by a Relay Node, RN, a current startup phase; and
transmitting, by the RN, to a serving eNB or Mobility Management Entity, MME, information for indicating the startup phase
which the RN is currently performing, wherein the transmitting particularly comprises:

when the RN is currently performing a startup phase I, the RN transmitting no information for indicating the startup phase
which the RN is currently performing to the eNB or the MME, and when the RN is currently performing a startup phase II, the
RN transmitting information for indicating that the RN is currently performing the startup phase II to the eNB or the MME;

wherein the information for indicating that the RN is currently performing the startup phase II is: a Globally Unique Temporary
Identity, GUTI.
