Description

Technical Field

[0001] This invention relates to the field of wireless technology, and in particular to a method, apparatus, terminal, and network-side device for Radio Resource Control (RRC) connection. Background Technology

[0002] Radio Resource Control (RRC) connection establishment is based on a random access procedure, which typically involves two information exchanges between the base station and the terminal.

[0003] However, with the development of communication technology, the above-mentioned random access procedure is not applicable to all scenarios. For example, in some scenarios, it is necessary to reduce the RRC establishment latency. For instance, when the UE needs to send and receive uplink and downlink data, or in an unlicensed new radio (NR-U) scenario, it is necessary to reduce the RRC establishment latency. In NR-U, because spectrum resources are shared with other systems (such as Wi-Fi or inter-carrier NR-U), a Listen Before Talk (LBT) process must be performed before each transmission. If LBT fails, data transmission cannot proceed. If the RRC connection establishment process has a large latency and involves many interactions, the connection may be successfully established, but the channel quality may no longer meet the current service quality (QoS) requirements.

[0004] Therefore, for the above scenarios, it is necessary to improve the random access process to reduce random access latency. Summary of the Invention

[0109] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0110] To effectively reduce the RRC connection establishment latency, this invention provides a method for RRC connection establishment using Radio Resource Control (RRC). This method can pre-send RRC connection configuration information related to RRC connection establishment to the terminal, allowing the terminal to begin establishing the RRC connection configuration during random access. This advances the establishment of the RRC connection configuration, reduces the number of messages required for RRC connection establishment, and thus reduces the latency of the RRC connection establishment process.

[0111] like Figure 1As shown, one embodiment of the RRC connection method of the present invention is applied to a terminal and includes:

[0112] S110, Receive at least one RRC connection configuration sent by the network-side device; wherein the RRC connection configuration is the configuration information used for the RRC connection;

[0113] S120, select the RRC connection configuration using one of the following methods to initiate the RRC connection process:

[0114] Randomly select the RRC connection configuration;

[0115] When each of the aforementioned RRC connection configurations corresponds to a service type and / or a terminal type, the corresponding RRC connection configuration is selected according to the service type and / or terminal type.

[0116] like Figure 2 As shown, during the RRC connection establishment process, the random access (RA) procedure typically involves two information exchanges between the base station and the terminal user, i.e., random access is performed through a four-step process. In the first interaction between the terminal and the base station, the terminal sends an uplink random access request on the Physical Random Access Channel (PRACH), i.e., message 1, which includes a preamble sequence. The base station calculates the timing deviation of the terminal based on the received preamble sequence and feeds back the random access response through the downlink channel, i.e., message 2, which includes synchronization and scheduling information for the next interaction. In the second interaction between the terminal and the base station, the terminal adjusts the user identifier or the user identifier from the core network according to the timing advance, resource allocation, power control, and other information indicated by the scheduling, and sends message 3 through PUSCH. Subsequently, the base station scrambles the user identifier through IE and sends message 4 to the terminal. Based on this process, the randomization process is completed when the scrambling identifier matches the user identifier, and the contention resolution identifier MAC control Element transmitted on the Downlink Shared Channel (DL-SCH) of message 4 matches the Common Control Channel Service Data Unit (CCCH SDU) transmitted in message 3.

[0117] In the aforementioned random access process, the RRC connection establishment latency includes the RA response window for message 2 reception and the contention resolution timer duration for message 4 reception. Although these can be set to relatively large values, messages 2 and 4 may actually be received very quickly. Therefore, the actual latency in these two steps depends on the base station implementation. The RRC processing time, compared to these two latencies, is a fixed duration, typically not exceeding 10ms, and in practice, the terminal's processing time for RRC messages is only a few milliseconds. Therefore, reducing the latency caused by this RRC processing time will effectively reduce the RRC connection establishment latency, and compared to the typical two-step random access process, it can guarantee superior RRC connection establishment latency performance.

[0118] Based on the above principles, the RRC connection method described in this embodiment of the invention sends at least one RRC connection configuration to the terminal before executing the random access procedure. This allows the terminal to simultaneously begin establishing an RRC connection configuration during the random access procedure. Furthermore, the terminal can send the adopted RRC connection configuration to the network side device, ensuring configuration consistency between the terminal and the network side device and enabling the RRC connection configuration to be established in advance, thereby reducing the latency of the RRC connection establishment process.

[0119] Optionally, in the RRC connection method described in this embodiment of the invention, step S110, receiving at least one RRC connection configuration sent by a network-side device, includes:

[0120] At least one RRC connection configuration sent by the receiving network-side device via broadcast or multicast.

[0121] Optionally, network-side devices can broadcast one or more RRC connection configurations via system information, or multicast or broadcast at least one RRC connection configuration via multicast / broadcast messages.

[0122] In one implementation, the RRC connection configuration may not have a corresponding relationship between service type and terminal type.

[0123] In another implementation, each RRC connection configuration corresponds to a service type and / or a terminal type.

[0124] Based on the RRC connection configuration sent by the network-side device, when each RRC connection configuration corresponds to a service type and / or a terminal type, the terminal can select the corresponding RRC connection configuration according to the service type and / or terminal type; in another implementation, regardless of whether the RRC connection configuration corresponds to the service type and / or terminal type, the terminal can randomly select the RRC connection configuration according to service requirements.

[0125] In this embodiment of the invention, the network-side device configures different RRC connection configurations for different service types and / or different terminal types. One service type can correspond to one or more RRC connection configurations, and one terminal type can correspond to one or more RRC connection configurations. Similarly, under one service type, one or more RRC connection configurations can be configured for one terminal type.

[0126] Therefore, specifically, each RRC connection configuration is used to indicate the configuration information used by the RRC connection when corresponding to a service type and / or a terminal type.

[0127] Optionally, the service type can be an access category in the Unified Access Control (UAC) mechanism or single network fragment selection auxiliary information sNSSAI.

[0128] In this embodiment, optionally, the RRC connection configuration includes at least one of the following information:

[0129] Signaling bearer configuration information;

[0130] Data carries configuration information;

[0131] An identifier used to indicate the host configuration;

[0132] Identifiers used to indicate RRC procedures;

[0133] Community group configuration information;

[0134] Identifier used to represent cell group configuration information.

[0135] Optionally, the RRC process includes RRC connection establishment, RRC reconfiguration, RRC connection recovery, and RRC connection switching.

[0136] Optionally, in the RRC connection method described in this embodiment of the invention, when selecting the corresponding RRC connection configuration based on the service type and / or terminal type, the method further includes:

[0137] Obtain the mapping relationship between the configuration identifier of the RRC connection configuration and the type identifier of the corresponding service type and / or the type identifier of the corresponding terminal type.

[0138] Optionally, this mapping relationship and the RRC connection configuration are transmitted to the terminal via the same send message.

[0139] Specifically, the network-side device assigns a configuration identifier to each RRC connection, such as... Figure 3As shown, each RRC connection configuration corresponds to a configuration identifier ID. Each service type's type identifier ID can correspond to one or more RRC connection configurations, and therefore can correspond to one or more configuration identifiers. Similarly, each terminal type's type identifier ID can correspond to one or more RRC connection configurations, and therefore can correspond to one or more configuration identifiers. Based on this, when a service type's type identifier ID also has a terminal type's type identifier ID, it can correspond to one or more configuration identifiers.

[0140] In this embodiment of the invention, optionally, in step S120, selecting the corresponding RRC connection configuration according to the service type and / or terminal type, and initiating the RRC connection process includes:

[0141] Send the configuration identifier of the RRC connection configuration selected for the RRC connection to the network-side device; or

[0142] The configuration identifier of the RRC connection configuration required for the RRC connection as instructed by the network-side device.

[0143] Optionally, the configuration identifier sent to the network-side device may be one or more, and the configuration identifier indicated by the received network-side device may also be one or more. When multiple configuration identifiers are included, they form an identifier combination.

[0144] This includes sending a configuration identifier for the RRC connection configuration used for the RRC connection to the network-side device, including:

[0145] The configuration identifier is sent to the network-side device via message 1 or message 3 of the random access procedure.

[0146] Optionally, the terminal's connection configuration can occur before, during, or after sending message 1 or message 3 that identifies the configuration.

[0147] Optionally, message 1 or message 3, which sends the configuration identifier, may also include an identity identifier used to identify the terminal.

[0148] The identity identifier for the terminal can be any one of the following: a random value, a Subscription Permanent Identifier (SUPI), or a Temporary Mobile Subscriber Identity (TMSI). It should be noted that the identity identifier used to identify the terminal is not limited to the above-mentioned identifiers; it can also be other identifiers that can identify the UE.

[0149] Optionally, the method further includes:

[0150] Receive configuration instruction information for RRC connection configuration sent by the network-side device;

[0151] The configuration indication information is used to confirm the RRC connection configuration selected by the terminal for RRC connection, or to modify the RRC connection configuration selected by the terminal for RRC connection, or to release the RRC connection configuration selected by the terminal for RRC connection.

[0152] Specifically, the network-side device can confirm, modify, or release the RRC connection configuration selected by the terminal. Optionally, the configuration indication information carries a configuration identifier of the RRC connection configuration to indicate the confirmed, modified, or released RRC connection configuration.

[0153] It should be noted that modifications to the RRC connection configuration selected by the terminal may include adding RRC connection configurations and / or modifying the configuration information of the RRC connection configuration.

[0154] Optionally, the configuration indication information may also include a terminal identifier assigned by the network-side device to the terminal for data transmission and reception.

[0155] Optionally, the method further includes:

[0156] The terminal sends configuration modification information for the RRC connection configuration to the network-side device;

[0157] The configuration modification information is used to modify the RRC connection configuration selected by the terminal for RRC connection, and / or the RRC connection configuration required for RRC connection as indicated by the network-side device.

[0158] Specifically, the network-side device sends configuration instruction information to the terminal, and the terminal sends configuration modification information to the network-side device. The network-side device can confirm, modify, or release the RRC connection configuration selected by the terminal. The terminal can modify the selected RRC connection configuration and the RRC connection configuration required for the RRC connection as indicated by the network-side device.

[0159] In the RRC connection method described in the embodiments of the present invention,

[0160] Before receiving at least one RRC connection configuration sent by the network-side device, the method further includes:

[0161] The decryption key for the RRC connection configuration is obtained through the Attach procedure or the Tracking Area Update (TAU) procedure.

[0162] In this way, by obtaining the decryption key in advance, the terminal can decrypt the message after receiving the message to send the RRC connection configuration and obtain the RRC connection configuration.

[0163] The method described in the embodiments of the present invention, such as Figure 4 As shown, the steps to obtain the RRC connection configuration sent by the network-side device include:

[0164] S410, the terminal obtains the decryption key from the core network for decrypting the RRC connection configuration;

[0165] S420, the network-side device sends at least one RRC connection configuration via broadcast or multicast;

[0166] S430, the terminal performs RRC connection configuration selection and application;

[0167] S440, the terminal sends an RRC connection establishment request to the network-side device to request the establishment of an RRC connection; or sends an RRC connection modification request, including configuration modification information, to instruct the terminal to modify the RRC connection configuration selected for the RRC connection, and / or the RRC connection configuration to be applied as indicated by the network-side device for the RRC connection.

[0168] S450, the network-side device sends configuration instruction information to the terminal to confirm the RRC connection configuration selected by the terminal for RRC connection, or to modify the RRC connection configuration selected by the terminal for RRC connection, or to release the RRC connection configuration selected by the terminal for RRC connection;

[0169] S460 enables uplink and downlink data transmission and reception between the terminal and network-side equipment.

[0170] The method described in the embodiments of the present invention is referred to in the following documents. Figure 1 In step S120, based on at least one of the RRC connection configurations, an RRC connection process is initiated, including:

[0171] Initiate an RRC connection establishment process, an RRC reconfiguration process, an RRC connection recovery process, or an RRC connection switching process.

[0172] The execution processes described above are illustrated below using examples of the method described in the embodiments of the present invention.

[0173] like Figure 5 As shown, in one embodiment, the process of initiating an RRC connection includes the following steps:

[0174] S510, the terminal receives the RRC connection configuration broadcast by the network-side device system information;

[0175] Optionally, the RRC connection configuration corresponds to the service. For example, if the terminal is about to initiate a URLLC service, the RRC connection configuration corresponding to that service type should be selected. Alternatively, if the terminal currently has no data transmission requirement, only the RRC connection configuration corresponding to system information SRB1 can be applied. Alternatively, the terminal can select the RRC connection configuration corresponding to voice based on the received paging message indication information (e.g., if the paging reason is voice).

[0176] S520, the terminal performs RRC connection configuration selection and application;

[0177] S530, the terminal sends an RRC connection establishment request to the network-side device;

[0178] Optionally, the RRC connection establishment request includes the selected and applied RRC connection configuration, a request identifier indicating that the request is for establishing an RRC connection, and a random number;

[0179] Optionally, the RRC connection establishment request can be message 3 in the random access procedure;

[0180] S540, the network-side device sends an RRC connection confirmation message to the terminal to confirm the RRC connection configuration sent by the terminal, and also carries the terminal identifier assigned to the terminal;

[0181] The S550 enables uplink and downlink data transmission and reception between the terminal and network-side equipment.

[0182] like Figure 6 As shown, in one embodiment, the process of initiating an RRC connection is to initiate an RRC reconfiguration, which includes the following steps:

[0183] S610, the terminal receives the RRC connection configuration broadcast by the network-side device system information;

[0184] S620, Terminal Storage RRC Connection Configuration;

[0187] S650, an application for configuring RRC connections on the terminal;

[0188] S660: The terminal sends an RRC connection reconfiguration completion message to the network-side device.

[0189] In the above implementation, the terminal can reconfigure the RRC connection based on the stored RRC connection configuration by using the RRC connection reconfiguration request including the configuration identifier sent by the network-side device.

[0190] like Figure 7 As shown, initiating an RRC connection involves performing an RRC reconfiguration. Another implementation includes the following steps:

[0191] S710, the terminal receives the RRC connection configuration broadcast by the network-side device system information;
