Method and apparatus for random access

A method for random access, comprising:

• sending, by a base station, an access indication message, wherein the access indication message comprises a User Equipment (UE) identifier and a corresponding resource number;
• if a Dedicated Physical Control Channel (DPCCH) preamble sent by a UE is detected, sending, by the base station, an acquisition indication to the UE;
• and
• if the DPCCH preamble sent by the UE is not detected, not sending, by the base station, the acquisition indication to the UE, or sending, by the base station, to the UE an indication indicating that the DPCCH preamble is not detected.

An apparatus for random access, comprising:

• a resource receiving module, configured to receive an access indication message, wherein the access indication message comprising a User Equipment (UE) identifier and a corresponding resource number;
• a preamble sending module, connected to the resource receiving module and configured to send a Dedicated Physical Control Channel (DPCCH) preamble by using an uplink resource corresponding to the resource number and a preset initial transmit power;
• and
• an access determination module, configured to determine that an access process succeeds when an acquisition indication is received.

An apparatus for random access, comprising:

• a resource information sending module, configured to send an access indication message, wherein the access indication message comprises a User Equipment (UE) identifier and a corresponding resource number;
• and
• an indication sending module, configured to send an acquisition indication to a UE if a Dedicated Physical Control Channel (DPCCH) preamble sent by the UE is detected;
• and
• the indication sending module is further configured to not send the acquisition indication to the UE, or to send the UE an indication indicating that the DPCCH preamble is not detected if the DPCCH preamble sent by the UE is not detected.
