RANDOM ACCESS METHOD, APPARATUS, AND SYSTEM
First Claim
1. A random access method, comprising:
- receiving, by a user equipment, configuration information notified by a base station including;
configuration information of a Physical Random Access Channel (PRACH) dedicated for a super real-time service and/or configuration information of a preamble dedicated for the super real-time service; and
in response to determining that the user equipment includes the super real-time service and includes a short Transmission Time Interval (TTI) support capability, by the user equipment, transmitting the preamble to the base station through a PRACH resource dedicated for the super real-time service or transmitting the preamble dedicated for the super real-time service to the base station according to the configuration information of the PRACH dedicated for the super real-time service and/or the configuration information of the preamble dedicated for the super real-time service, so as to trigger the base station to allocate a short TTI resource to the user equipment.

Abstract
Provided are a random access method, apparatus and system. The method includes: receiving, by a user equipment, configuration information of a Physical Random Access Channel (PRACH) dedicated for a super real-time service and/or configuration information of a preamble dedicated for the super real-time service notified by a base station; and when the user equipment has the super real-time service and has a short Transmission Time Interval (TTI) support capability, by the user equipment, transmitting a preamble to the base station through a PRACH resource dedicated for the super real-time service or transmitting the preamble dedicated for the super real-time service to the base station according to the configuration information of the PRACH dedicated for the super real-time service and/or the configuration information of the preamble dedicated for the super real-time service, so as to trigger the base station to allocate a short TTI resource to the user equipment.

5. A random access method, comprising:
-
identifying, by a base station, a preamble transmitted from a user equipment; and in response to determining that the base station identifies that the preamble received is a preamble transmitted from the user equipment through a Physical Random Access Channel (PRACH) resource dedicated for a super real-time service or a preamble dedicated for the super real-time service, transmitting, by the base station, the user equipment a Random Access Response (RAR) carried with resource allocation information for a short Transmission Time Interval (TTI). - View Dependent Claims (6, 7, 8)

9. A random access apparatus provided in a user equipment, comprising a processor and a storage device storing computer executable instructions that, when executed by the processor, cause the processor to perform the following method:
-
receiving configuration information notified by a base station, including configuration information of a Physical Random Access Channel (PRACH) dedicated for a super real-time service and/or configuration information of a preamble dedicated for the super real-time service; and in response to determining that the user equipment includes the super real-time service and includes a short Transmission Time Interval (TTI) support capability, transmitting the preamble to the base station through a PRACH resource dedicated for the super real-time service or transmitting the preamble dedicated for the super real-time service to the base station according to the configuration information of the PRACH dedicated for the super real-time service and/or the configuration information of the preamble dedicated for the super real-time service, so as to trigger the base station to allocate a short TTI resource to the user equipment. - View Dependent Claims (10, 11, 12, 17)

13. A random access apparatus provided in a base station, comprising a processor and a storage device storing computer executable instructions that, when executed by the processor, cause the processor to perform the steps in following method:
-
identifying a preamble transmitted from a user equipment; and in response to identifying that the preamble received is a preamble transmitted from the user equipment through a Physical Random Access Channel (PRACH) resource dedicated for a super real-time service or a preamble dedicated for the super real-time service, transmitting the user equipment a Random Access Response (RAR) carried with resource allocation information for a short Transmission Time Interval (TTI). - View Dependent Claims (14, 15, 16, 18)
