Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Fig. 1 illustrates a network architecture diagram in a dual connectivity scenario provided by an exemplary embodiment of the present application.

As shown in fig. 1, in the case where the terminal 110 connects the first base station 120 and the second base station 130 at the same time, the first base station 120 is a Master Node (MN), the second base station 130 is a Secondary Node (SN), the terminal 110 first accesses the first base station 120 as a Master Node, and then adds the second base station 130 as a Secondary Node as needed. Wherein the primary node is also referred to as an "anchor point", the first base station 120, which is the primary node, is responsible for interacting with the control plane of the core network 140.

Either the first base station 120 or the second base station 130 supports carrier aggregation for multiple carriers/cells within the base station. Therefore, for at least two cells of the first base station 120 as a master node, referred to as a master Cell group (Master Cell Group, MCG) 121, the master Cell group 121 includes a Primary Cell (Pcell) 1211 and a plurality of Secondary cells (scells) 1212. For at least two cells of the second base station 130 as secondary nodes, referred to as secondary cell group (Secondary Cell Group, SCG), the secondary cell group 131 contains a primary secondary cell (Primary Secondary Cell, PSCell) 1311, and a plurality of secondary cells 1312.

The following is a detailed description of four dual connections:

1. EN-DC scenario: in this connection scheme, a user terminal connects an E-UTRA base station and an NR base station simultaneously. Wherein the E-UTRA base station (also called LTE base station) is a primary node, the NR base station is a secondary node, and the primary node is connected to an evolved packet core (Evolved Packet Core, EPC);

2. NGEN-DC scenario: in this connection scheme, a user terminal connects an E-UTRA base station and an NR base station simultaneously. Wherein, E-UTRA base station is the main node, NR base station is the auxiliary node, the main node connects to 5G core network (5G Core Network,5CG);

3. NE-DC (New Radio E-UTRA Dual Connectivity with NR Connected to GC) scenario: in the connection mode, a user terminal is simultaneously connected with an E-UTRA base station and an NR base station, wherein the NR base station is a main node, the E-UTRA base station is an auxiliary node, and the main node is connected to 5CG;

4. NR-DC (New Radio Dual Connectivity with NR Connected to GC) scenario: in the connection mode, the user terminal is connected with two NR base stations at the same time, wherein one NR base station is a main node, the other NR base station is an auxiliary node, and the main node is connected to the 5GC.

In the related protocol, RAN3 has completed the work of network interface signaling interworking to support SN RACH Report in the above four dual connectivity scenarios, but for RAN2, only SN RACH Report in the NR-DC scenario is currently supported, but SN RACH Report in the EN-DC, NGEN-DC and NE-DC scenarios are not yet supported. Therefore, in order to solve the technical problem of supporting the SN RACH Report in the EN-DC scenario and the nen-DC scenario, the present application provides a random access reporting method, as shown in the following embodiments.

Regarding signaling radio bearer3 (Signalling Radio Bearer, SRB 3), SRB3 is used for signaling interactions between the terminal and the secondary node. When the auxiliary node is a base station in an EN-DC scene/NGEN-DC scene/NR-DC scene, the terminal and the auxiliary node can be configured to establish SRB3, so that a radio resource control (Radio Resource Control, RRC) protocol data unit (Protocol Data Unit, PDU) of the auxiliary node can be directly transmitted between the terminal and the auxiliary node, and the RRC PDU corresponding to the auxiliary node can be directly transmitted to the terminal for the RRC reconfiguration of the auxiliary node without coordination with the main node. If SRB3 is configured between the terminal and the secondary node, the mobility measurement report may be directly reported from the terminal to the secondary node.

The names of base station enabled devices may vary in systems employing different radio access technologies, for example in long term evolution (Long Term Evolution, LTE) systems, called enodebs or enbs; in the 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the description of "base station" may change. The access network 22 may be constructed using at least one of the two-connection techniques described above for both NGEN-DC and EN-DC.

The core network includes a number of core network devices 26. The core network functions to take charge of the exchange, routing, user data management, security, etc. of information inside the system and the exchange and transmission of information with other communication systems.

The technical solution of the embodiment of the present disclosure may be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile Communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, general packet Radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) system, LTE frequency division duplex (Frequency Division Duplex, FDD) system, LTE time division duplex (Time Division Duplex, TDD) system, long term evolution advanced (Advanced long Term Evolution, LTE-a) system, new Radio (NR) system, evolution system of NR system, LTE (LTE-based access to Unlicensed spectrum, LTE-U) system on unlicensed frequency band, NR-U system, universal mobile telecommunication system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication system, wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, wiFi), next generation communication system or other communication system, etc.

Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, as the communication technology advances, the mobile communication system will support not only conventional communication but also, for example, device-to-Device (D2D) communication, machine-to-machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), inter-vehicle (Vehicle to Vehicle, V2V) communication, and internet of vehicles (Vehicle to Everything, V2X) systems, etc. Embodiments of the present disclosure may also be applied to these communication systems.

Fig. 3 is a flowchart illustrating a random access reporting method according to an exemplary embodiment of the present disclosure, which is applied to the communication system shown in fig. 2 and is performed by a terminal, the method including:

step 310: performing at least one of the following operations:

record only random access RA information of NR cells;

reporting RA information to the secondary node.

In some embodiments, the above method is directed to any one of the following dual connectivity scenarios: E-UTRA and NR dual-linked NGEN-DC linked to 5 GC; E-UTRA and NR connected to EPC are dual-connected to EN-DC.

In the NGEN-DC scene, in the connection mode, the user terminal is simultaneously connected with the E-UTRA base station and the NR base station. Wherein, E-UTRA basic station is the master node, and NR basic station is the auxiliary node, and the master node is connected to 5GC.

In the EN-DC scene, in the connection mode, the user terminal is simultaneously connected with the E-UTRA base station and the NR base station. Wherein, E-UTRA basic station is the main node, NR basic station is the auxiliary node, and main node is connected to EPC.

In some embodiments, the terminal records RA information of only NR cells, including recording at least one of the following to RA reporting variables (VarRA-Report):

if the terminal initiates random access in at least one cell in the SCG, determining to record RA information of the cell;

for example, if the terminal initiates random access in a primary cell and a secondary cell in the SCG, determining to record RA information of the primary cell and the secondary cell; or if the terminal initiates random access in the secondary cell in the SCG, determining to record RA information of the secondary cell; or if the terminal initiates random access in the primary and secondary cells in the SCG, determining to record RA information of the primary and secondary cells.

If the terminal initiates random access in at least one cell in the MCG, it is determined that RA information of that cell is not recorded.

For example, if the terminal initiates random access in a primary cell in the MCG, determining that RA information of the primary cell is not recorded; or if the terminal initiates random access in the auxiliary cell in the MCG, determining that RA information of the auxiliary cell is not recorded; or if the terminal initiates random access in the primary cell and the secondary cell in the MCG, determining that RA information of the primary cell and the secondary cell is not recorded.

Illustratively, the RA information of the NR cell includes the RA information of the SCG cell.

In some embodiments, "NR cells" and "SCG cells" are the same concept.

In some embodiments, RA information of the SCG cell is recorded in an RA reporting variable.

Optionally, the terminal directly reports RA information of the SCG cell; alternatively, the terminal reports RA information of the SCG cell stored in the RA report variable, which is not limited.

Optionally, the RA information of the SCG cell includes RA information of the SCG primary and secondary cells and/or RA information of the SCG secondary cells.

In some embodiments, RA information of the SCG cell is reported to the secondary node; and/or reporting RA information of the MCG cell to the auxiliary node.

In some embodiments, in response to receiving the RA information reporting request sent by the secondary node, the terminal further reports RA information of the MCG cell. For example, RA information of the MCG cell and RA information of the SCG cell are reported simultaneously, or reported separately.

Optionally, the RA information of the MCG cell includes RA information of the MCG primary cell and/or RA information of the MCG secondary cell.

Optionally, the terminal reporting RA information includes at least one of:

first, the terminal reports by itself.

In some embodiments, the terminal reports RA information of the available SCG cells to the secondary node by itself, i.e. the terminal reports RA information of the available SCG cells by itself without receiving a RA information reporting request sent by the secondary node.

In some embodiments, the terminal reports the RA information of the available MCG cells and/or the RA information of the SCG cells to the auxiliary node by itself, i.e. without receiving the RA information reporting request sent by the auxiliary node, the terminal reports the RA information of the available MCG cells and/or the RA information of the SCG cells to the auxiliary node by itself. The auxiliary node sends RA information of the MCG cell to the main node.

And secondly, reporting after receiving the RA information reporting request.

In some embodiments, RA information is reported to the secondary node in response to receiving a RA information reporting request sent by the secondary node.

In one possible case, the RA information reporting request is implemented as an independent MN RA information reporting request and/or an independent SN RA information reporting request.

Illustratively, in response to receiving an RA information reporting request, RA information of the SCG cell and/or the MCG cell is reported to the secondary node, where the RA information reporting request is used for requesting the terminal to report RA information of the SCG cell and/or the MCG cell.

For example, the terminal receives an independent MN RA information reporting request sent by the auxiliary node, and reports RA information of available MCG cells to the auxiliary node; and the terminal receives an independent SN RA information reporting request sent by the auxiliary node and reports RA information of the available SCG cells to the auxiliary node.

In one possible case, the RA information reporting request is not distinguished into an independent MN RA information reporting request and an independent SN RA information reporting request.

For example, an SN RA information reporting request sent by the secondary node is predefined, and is used for requesting the terminal to report RA information of the SCG cell only. When the terminal receives the RA information reporting request, the RA information of the SCG cell is only reported to the auxiliary node.

In some embodiments, in response to receiving an RA information reporting request sent by the secondary node, RA information of an available SCG cell and/or an MCG cell is reported to the secondary node, where the RA information reporting request is used for requesting the terminal to report RA information of the SCG cell and/or the MCG cell. The RA information reporting request may be predefined by a protocol, or may be determined by the terminal according to the cache content of the RA report variable, or may be determined by an indication bit in the RA information reporting request, which is not limited in this embodiment.

For example, the terminal reports the available SCG cells and/or RA information of the MCG cells to the auxiliary node according to the cache content of the RA report variable in the received RA information reporting request sent by the auxiliary node.

For another example, the terminal receives an RA information reporting request sent by the auxiliary node, where the RA information reporting request carries a designated bit, and the designated bit is used to indicate RA information requested to be reported in the RA information reporting request.

Optionally, when the RA information reporting request carries the first value of the designated bit, the terminal receives the RA information reporting request sent by the auxiliary node, and reports RA information of the available SCG cell to the auxiliary node.

Optionally, when the RA information reporting request carries the second value of the designated bit, the terminal receives the RA information reporting request sent by the auxiliary node, and reports RA information of the available MCG cell to the auxiliary node.

Optionally, when the RA information reporting request carries the third value of the designated bit, the terminal receives the RA information reporting request sent by the auxiliary node, and reports RA information of the available MCG cell and RA information of the SCG cell to the auxiliary node.

The first, second and third values are different.

In some embodiments, the RA information report request is carried in a UE information request message; the RA information is carried in a UE information response message.

In some embodiments, the terminal further reports capability information, where the capability information is used to indicate whether the terminal supports RA information reporting of the SCG cell. Optionally, before the terminal reports the capability information, the auxiliary node sends a capability request or a capability reporting indication to the terminal.

In some embodiments, the terminal also reports an availability indication indicating RA information of NR cells for which the terminal has availability.

In some embodiments, after the RA information is successfully reported, the terminal discards the RA information that is successfully reported; or, after delaying the first time length, discarding the RA information. Illustratively, the start time for delaying the first duration is: recording time of the RA information, or reporting time of the RA information, or successful reporting time of the RA information. The first duration is a predefined, or preconfigured, or dynamically configured value, such as 48 hours.

In some embodiments, the RA information report request and/or RA information is transmitted through SRB 3.

In summary, the method provided in this embodiment performs at least one of the following operations: recording RA information of the SCG cell only; and reporting the RA information to the auxiliary node. The method is used for supporting the terminal to execute at least one operation of recording RA information of the SCG cell and reporting the RA information in an NGEN-DC scene and an EN-DC scene.

For the above-mentioned ngan-DC scenario and EN-DC scenario, the E-UTRA base station (or LTE base station) is a primary node, and the NR base station is a secondary node, in this embodiment, the MCG for carrier aggregation in the E-UTRA base station is referred to as an E-UTRAN cell or an LTE cell or an MCG cell, and the SCG for carrier aggregation in the NR base station is referred to as an NR cell or an SCG cell. It should be understood that "E-UTRAN cell or LTE cell or MCG cell" may be regarded as the same concept and "NR cell or SCG cell" may be regarded as the same concept.

The method provided by the embodiment of the application supports the NGEN-DC scene and the terminal reporting the RA information of the SCG cell to the auxiliary node under the EN-DC scene.

Illustratively, the RA information reporting request is for requesting the terminal to report RA information of at least one cell. Illustratively, the RA information of at least one cell includes: RA information of MCG cells; or RA information of the SCG cell; alternatively, the RA information of the MCG cell and the RA information of the SCG cell are not limited thereto.
