in step 110, a terminal is allocated a specific uplink carrier used when the terminal initiates a specific type of random access.

In the embodiments of the present disclosure, the specified type of random access may be one or more types of random access specified by the base station. The designated uplink carrier may be a carrier that is good and stable in signal and that is allocated by the base station for these different types of random access.

Such as: the designated type 1 corresponds to the designated uplink carrier 1, and the designated type 2 corresponds to the designated uplink carrier 2. The uplink carrier 1 and the designated uplink carrier 2 may be the same or the same, but both are allocated by the base station for the designated type 1 and the designated type 2 according to the actual situation.

In one embodiment, the specified type in step 110 may be identified by at least one of the following information:

(1) a service identity is specified.

In this embodiment, the specified service identifier may be applicable to random access initiated by a terminal in an idle state or an inactive state, or may be applicable to random access initiated by a terminal in a connected state, and in particular, for random access initiated by a terminal in a connected state, the method is only applicable to random access triggered by the terminal itself.

The different types of random access may be divided by different service identities, where the different service identities may include, but are not limited to, the following three types:

(1-1) critical machine Type Communication (critical mtc) Type traffic, such as data of health monitoring devices;

(1-2) mass Machine Type Communication (mMTC) Type services, such as meter reading Type services;

(1-3) Mobile Broadband (MBB) type services, such as video type services.

And the base station can allocate uplink carriers with good and stable signals for the random access initiated by each service identifier. Such as: for the critical mtc type service, since the service has a high reliability requirement, the base station may allocate the SUL carrier to the critical mtc type service.

(2) An access identity (access identity) and/or an access category (access category).

In this embodiment, the different types of random accesses may be divided by different access identifiers, by different access categories, or by different access identifiers and access categories.

As an embodiment, the specific access identifier and/or the specific access category may be applicable to random access initiated by a terminal in an idle state or an inactive state, and may also be applicable to random access initiated by a terminal in a connected state.

(3) A specified call type (callType) and/or a specified connection establishment cause (estabilishcause).

As an embodiment, the specified call type and/or the specified connection establishment cause may be applicable to random access initiated by a terminal in an idle state or an inactive state.

(4) Specifying the type as a specified quality of service class identifier (QCI); wherein, QCI is also called 5G Quality of Service identifier (5 gqosidenifier, 5QI), and QoS is the abbreviation of Quality of Service (Quality of Service).

In this embodiment, the different types of random access may be divided by different QCIs, that is, may be divided by different 5 QIs. The 5QI value may be B, C or another different value. Such as: when the value of 5QI is B, the corresponding Example service (instance Services) is Remote control (Remote control); when the value of 5QI is C, the corresponding Example service (Example Services) is an Intelligent transportation system (Intelligent transportation systems).

As an embodiment, the QCI may be adapted for random access initiated by a connected terminal.

(5) Slice identification (Slice ID) is specified.

In this embodiment, different types of random accesses are divided, and the different types of random accesses may be divided by different slice identifiers.

As an embodiment, the slice identifier may be applicable to random access initiated by a terminal in a connected state.

In a new generation of communication systems, a network slicing (network slicing) technique is introduced, which allows a network (core network and access network) to be divided into multiple slices (slices), and different services are transmitted in different slices (slices) without interfering with each other. Such as: enhanced Mobile Broadband (eMBB) services are implemented in one slice (slice), while Low-Latency and high-reliability Communication (URLLC) services are implemented in another slice (slice).

(6) Specifying a protocol data unit session identification (PDU session ID) or a protocol data unit session identification (PDU session ID) and a quality of service flow identification (QoSflowID); the PDU is a short name of a Protocol Data Unit (Protocol Data Unit).

In this embodiment, the different types of random accesses are divided by different PDU session IDs, or by different PDU session IDs and qosflowids.

As an embodiment, the specified pdu session id and the specified qos flow id may be applicable to random access initiated by a terminal in a connected state.

(7) A Data Radio Bearer identity (DRB ID) is specified or a DRB ID and a quality of service flow identity (QoSflowID) are specified.

In this embodiment, the different types of random access may be divided by different DRB IDs, or may be divided by different DRB IDs and qosflowids.

As an embodiment, the specified data radio bearer identification and the specified quality of service flow identification may be adapted for random access initiated by a terminal in a connected state.

In an embodiment, the designated uplink carrier in step 110 may be a SUL carrier or a non-SUL carrier of a cell.

In step 120, carrier configuration information is generated, where the carrier configuration information is used to characterize the designated type and the designated uplink carrier configured by the base station.

In the embodiment of the present disclosure, the designated type and the designated uplink carrier are corresponding, that is, when the terminal initiates random access of the designated type, the designated uplink carrier configured by the base station is used.

In step 130, transmitting the carrier configuration information to the terminal; here, the carrier configuration information is sent to the terminal so that when initiating the random access of the specified type, the terminal initiates the random access of the specified type on the specified uplink carrier.

The application scenario shown in fig. 2 includes a terminal and a base station. In order to improve the success rate of random access of the terminal, the base station provides a random access method, namely, the base station configures the random access of a specified type to initiate the random access on a specified uplink carrier, the method can be suitable for the random access initiated by the terminal in an idle state or an inactive state, can also be suitable for the random access initiated by the terminal in a connected state, and is especially suitable for the random access initiated by the terminal in the connected state, and the method is only suitable for the random access triggered by the terminal. The concrete implementation is as follows: the base station distributes appointed uplink carriers used when the terminal initiates random access of an appointed type for the terminal, generates carrier configuration information, and the carrier configuration information is used for representing the appointed type and the appointed uplink carriers configured by the base station and sending the carrier configuration information to the terminal; after receiving the carrier configuration information sent by the base station, the terminal initiates random access of the specified type on the specified uplink carrier when initiating random access of the specified type, so that the random access of different types can be ensured to initiate corresponding random access on the uplink carrier with good and stable signals, thereby avoiding high time delay caused by random access failure and also improving the success rate and speed of random access.

It can be seen from the above embodiments that, by allocating a designated uplink carrier for the terminal to use when the terminal initiates a random access of a designated type, and generating carrier configuration information, where the carrier configuration information is used to characterize the designated type and the designated uplink carrier configured by the base station, and sending the carrier configuration information to the terminal, when initiating the random access of the designated type, the terminal can initiate the random access of the designated type on the designated uplink carrier, thereby ensuring that different types of random accesses can initiate corresponding random accesses on uplink carriers with good and stable signals, avoiding high delay caused by random access failure, and further improving success rate and speed of the random access.

Fig. 3 is a flowchart illustrating another random access method according to an exemplary embodiment, which may be applied to a base station and is based on the method shown in fig. 1, and when the carrier configuration information is sent to a terminal in step 130, the random access method may be sent to the terminal through a system message and/or a dedicated RRC message, as shown in fig. 3, and may include step 310 and/or step 320:

in step 310, the carrier configuration information is added to a system message and the system message is transmitted to the terminal.

In the embodiment of the present disclosure, after the base station adds the carrier configuration information to the system message and sends the system message to the terminal, the terminal may acquire the carrier configuration information from the system message.

In an embodiment, the base station may be a Master Cell Group (MCG) base station or a Secondary Cell Group (SCG) base station.

And the carrier configuration information is also configured for the MCG and the SCG respectively, so that if the random access is initiated on the uplink carrier of the cell of the MCG, the uplink carrier is selected according to the carrier configuration information for the cell of the MCG; similarly, if the random access is initiated on the uplink carrier of the SCG cell, the uplink carrier is selected according to the carrier configuration information for the SCG cell. The Cell may be a Primary serving Cell (Pcell) or a Secondary serving Cell (Scell).

In an embodiment, the System message is specifically SIB1(System Information Block), and the SIB1 is System message 1 in a Long Term Evolution (LTE) network.

In an embodiment, when the carrier configuration information is added to the system message in step 310, the carrier configuration information may be added to an Access barring (Access barring) configuration of the system message.

In a new generation communication system, Access barring (Access barring) may be supported, and the Access barring (Access barring) may be applicable to random Access initiated by a terminal in an idle state or an inactive state, and may also be applicable to random Access initiated by a terminal in a connected state.

As an embodiment, if Access barring (Access barring) configuration indicates that a specified type of random Access is barred on one uplink carrier but not barred on another uplink carrier, the terminal may initiate the specified type of random Access through the barred uplink carrier.

In step 320, the carrier configuration information is added to a dedicated RRC (Radio Resource Control) message, and the dedicated RRC message is sent to the terminal.

In the embodiment of the present disclosure, after the base station adds the carrier configuration information to the dedicated RRC message and sends the dedicated RRC message to the terminal, the terminal may acquire the carrier configuration information from the dedicated RRC message.

In the embodiment of the present disclosure, the valid time may be system-agreed or network-configured, such as: within 300 seconds. The effective Area may also be system-defined or network-configured, and if system-defined, may be limited to only the cell at the time of connection release and/or a RAN-based Notification Area (RNA) and/or a Tracking Area (TA); if network configured, a cell list and/or a RAN-based notification area list and/or a tracking area list may be configured. The RAN is a short for Radio Access Network (Radio Access Network).

As can be seen from the above embodiments, by adding carrier configuration information to a system message, and sending the system message to a terminal; and/or adding the carrier configuration information into the special RRC message, and sending the special RRC message to the terminal, thereby improving the reliability of the transmission of the carrier configuration information, meeting the individual requirements of random access initiated by different terminals in an idle state or an inactive state, a connected state terminal and the like, and improving the efficiency of the random access.
