Detailed Description

So that the manner in which the features and techniques of the embodiments of the present invention can be understood in more detail, a more particular description of the invention, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present invention.

Before describing embodiments of the present invention in detail, a brief description of a dual connectivity (Dual Connectivity, DC) technique is first provided.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of future life services, the 3GPP international standards organization starts to develop 5G for this purpose. The main application scenario of 5G is: enhanced mobile ultra-wideband (emmbb), low latency high reliability communication (URLLC), large-scale machine type communication (mctc).

embbs still target users to obtain multimedia content, services, and data, and their demand is growing very rapidly. On the other hand, since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of the eMBB are also relatively different, so that detailed analysis must be performed in connection with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At the early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area long term evolution (Long Term Evolution, LTE) coverage and New Radio (NR) island coverage mode. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a tight interworking mode of operation between LTE and NR is proposed.

In order to enable 5G network deployment and commercial applications as soon as possible, 3GPP first completes the first 5G release, LTE-NR Dual Connectivity, abbreviated EN-DC, before 2017, 12. The network deployment and networking architecture of EN-DC is shown in fig. 1: here, LTE is a Master Node (MN), and NR is a Secondary Node (SN).

An optional processing flow of the access network node management method applied to the terminal device provided by the embodiment of the invention, as shown in fig. 4, includes the following steps:

in step S201, a terminal device receives first configuration information, where the first configuration information is used to indicate that the terminal device is configured with a first access network node and at least two second access network nodes.

In some embodiments, a terminal device receives radio resource control (Radio Resource Control, RRC) signaling sent by a network device, where the RRC signaling carries first configuration information, where the first configuration information is used to indicate that the terminal device is in a multi-connection mode, i.e. the terminal device is configured with one first access network node and at least two second access network nodes.

In the embodiment of the present invention, the scenario in which one first access network node and at least two second access network nodes are configured for the terminal device includes at least the following two scenarios. The network architecture of the first scenario, as shown in fig. 5, the first access network node and at least two second access network nodes connect to the first core network; in this scenario, there is a control plane connection between the first access network node and the first core network; the first access network node is an eLTE eNB, and the second access network node is a gNB; or the first access network node is gNB, and the second access network node is eLTE eNB; the coverage areas of the at least two second access network nodes may or may not overlap; the coverage areas of the first access network node and the second access network node are overlapped; in a first scenario, the first core network is a 5G core network. The network architecture of the second scenario, as shown in fig. 6, where the first access network node and at least two second access network nodes are connected to a second core network; in this scenario, there is a control plane connection between the first access network node and the second core network; the first access network node is an LTE eNB, and the second access network node is at least one of the following: LTE eNB, gNB, eLTE eNB; the coverage areas of the at least two second access network nodes may or may not overlap; the coverage areas of the first access network node and the second access network node are overlapped; in a second scenario, the first core network is an evolved packet core network (Evolved packet Core network, EPC).

In some embodiments, the first configuration information is further for indicating a unique Identity (ID) of the second access network node for the terminal device; i.e. each second access network node is assigned a unique identification, i.e. SN ID, for the terminal device. The SN ID may be assigned from 0 or 1; when the value of SN ID is allocated starting from 1, the ID of the first access network node may be defaulted to 0.

In some embodiments, the state of the second access network node comprises: a first state, a second state, and a third state. When the second access network node is in the first state, the state of the cell served by the second access network node includes: a first state, a second state, and a third state. When the second access network node is in the second state, the state of the cell served by the second access network node includes: and a second state. When the second access network node is in the third state, the state of the cell served by the second access network node includes: a second state and a third state. Optionally, when the cell served by the second access network node is in the third state, the terminal device performs RRM measurement and CQI measurement in the cell, and does not perform data transmission and data reception. In the embodiment of the present invention, the data transmission refers to sending data.

When the second access network node is in the first state, the terminal device is capable of performing at least one of: receiving and/or transmitting data of a cell in a first state, measuring radio resource management (Radio Resource Management, RRM) of the cell in the first state, measuring RRM of the cell in a second state, measuring RRM of the cell in a third state, measuring channel quality indications (Channel Quality Indication, CQI) of the cell in the first state and the cell in the third state, listening to and/or receiving a physical downlink control channel (Physical Downlink Control Channel, PDCCH) of the cell in the first state, transmitting a PDCCH of the cell in the first state, transmitting a channel sounding reference signal (Sounding Reference Signal, SRS) of the cell in the first state, and transmitting a scheduling request (Scheduling Request, SR) of the cell in the first state.

When the second access network node is in a second state, the terminal device is capable of performing at least one of: stopping receiving and/or transmitting data of the cell in the second state, measuring RRM of the cell in the second state, stopping measuring CQI of the cell in the second state, stopping monitoring and/or receiving PDCCH of the cell in the second state, stopping transmitting SRS of the cell in the second state, and stopping transmitting SR of the cell in the second state.

When the second access network node is in a third state, the terminal device is capable of performing at least one of: stopping receiving and/or transmitting data of the cells in the second state and the third state, measuring RRM of the cells in the second state, measuring CQI of the cells in the second state, measuring RRM of the cells in the third state, measuring CQI of the cells in the third state, stopping monitoring and/or receiving PDCCH of the cells in the second state and the third state, stopping transmitting PDCCH of the cells in the second state, stopping transmitting SRS of the cells in the second state, stopping transmitting SR of the cells in the second state, stopping transmitting PDCCH of the cells in the third state, stopping transmitting SRS of the cells in the third state, and stopping transmitting SR of the cells in the third state.

In some embodiments, the terminal device determines a first state or a second state of the second access network node according to the first signaling; optionally, the first signaling is PDCCH and/or MAC CE. For example, when the first signaling indicates that the second access network node with the ID of S1 is switched from the second state to the first state, the bit value corresponding to S1 in the first signaling is 0 or 1, which is used to indicate that the second access network node with the ID of S1 is in the first state. When the first signaling indicates that the second access network node is switched from a second state to a first state, the first signaling carries a random access channel (Random Access Channel, RACH) resource configuration; the RACH resource configuration is that Spcel1 in the second access network node initiates RACH resource configuration special for a random access process; optionally, the RACH resource configuration includes a preamble code and a RACH occalation configuration. And when the first signaling indicates that the second access network node is switched from the first state to the second state or the third state, the RACH resource is not configured. As shown in fig. 7, the configured RACH resources may correspond to each other in the order of the identification SN IDs of the second access network node requiring RACH resources, such as RACH in the order of SN IDs from small to large, or RACH in the order of SN IDs from large to small; when more than two SNs are activated at the same time, S1 to S7 correspond one by one in the order of SN IDs from small to large. In specific implementation, the state of the second access network node may also be controlled separately, where the format of the MAC CE is shown in fig. 8; optionally, the MAC CE controls the second access network node to switch from the second state to the first state, or from the third state to the first state.

In further embodiments, the terminal device determines a third state of the second access network node based on the first signaling. Optionally, the first signaling is PDCCH and/or MAC CE. When the second access network node is indicated to be in the second state or the third state by the MAC CE, a format diagram of the MAC CE is shown in fig. 9; the method comprises the steps that the MAC CEs used for indicating the second access network node to be in a second state and the MAC CEs in a third state are two different MAC CEs, the two different MAC CEs have the same format and respectively correspond to two different Logic Channels (LCs), and the MAC CEs are identified through different LC IDs; for example, if the MAC CE is used to indicate that the second access network node is in the second state, the LC ID corresponding to the MAC CE is 1; if the MAC CE is used to indicate that the second access network node is in the third state, the LC ID corresponding to the MAC CE is 0. Or if the MAC CE is configured to indicate that the second access network node is in the second state, an LC ID corresponding to the MAC CE is 0; if the MAC CE is used for indicating that the second access network node is in the third state, the LC ID corresponding to the MAC CE is 1; s1 to S7 are in one-to-one correspondence in the order of SN IDs from small to large. Or when the second access network node is indicated to be in the second state or the third state by the MAC CE, a format diagram of the MAC CE is shown in fig. 10; the MAC CEs used for indicating the second access network node to be in the second state and the third state are the same MAC CEs and correspond to one LC ID; optionally, flag has a value of 0 or 1; when the value of Flag is 0, the Flag is used for indicating that the second access network node is in a third state, and when the value of Flag is 1, the Flag is used for indicating that the second access network node is in a second state; or when the value of Flag is 1, the Flag is used for indicating that the second access network node is in the third state, and when the value of Flag is 0, the Flag is used for indicating that the second access network node is in the second state. S1 to S7 are in one-to-one correspondence in the order of SN IDs from small to large.

In further embodiments, the terminal device determines the state of the second access network node from a timer. For example, the terminal device determines that the second access network node is switched from the first state to the second state based on a timer; in a specific implementation, when the second access network node enters the first state, the terminal device starts a second timer, and when the second timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the first state to the second state. For another example, the terminal device determines that the second access network node is switched from the first state to the third state based on a timer; in a specific implementation, when the second access network node enters the first state, the terminal device starts a third timer, and when the third timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the first state to the third state. For another example, the terminal device determines that the second access network node is switched from the third state to the second state based on a timer; in a specific implementation, when the second access network node enters the third state, the terminal device starts a fourth timer, and when the fourth timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the third state to the second state.

As shown in fig. 11, the transition relationship between the three states of the second network node may be converted between the first state and the second state, where the conversion between the first state and the second state refers to that the first state may be switched to the second state, and the second state may be switched to the first state; the first state and the third state can be mutually switched, namely the first state can be switched to the third state, and the third state can also be switched to the first state. The third state can only be switched to the second state, and the second state cannot be switched to the third state, i.e. when the second access network node is in the second state, the second access network node cannot be switched to the third state.

In the embodiment of the invention, the state of the second access network node can be initially configured through RRC signaling; for example, the state of the second access network node is initially configured to be the first state, or the second state, or the third state by RRC signaling. Or defaults to the second access network node being in the first state, or the second state, or the third state by RRC signaling. And when the second access network node is in the second state, the path corresponding to the second access network node does not transmit and/or does not receive data.

In the embodiment of the invention, when the terminal equipment indicates to configure more than two second access network nodes through the first configuration information, the first configuration information is also used for indicating the grouping information of the at least two second access network nodes. The at least second access network node groups based on at least one of: the radio frequency range in which the second access network node is located, and whether the second access network node has a first connection with said first access network node. The grouping information includes at least one of: a group ID of the second access network node group, and a particular second access network node within the second access network node group. In a specific implementation, configuring a group ID for each second access network node group, and allocating a second access network node as a specific second access network node for each second access network node group; alternatively, the specific second access network node is referred to as a specific SN (SPSN), or Primary SN (PSN). The specific second access network node establishes control plane connection with the first access network node; optionally, the specific second access network node establishes a control plane connection of Xn or X2 with the first access network node, and is responsible for receiving the core network configuration parameters forwarded from the first access network node, such as QoS parameters. The specific second access network node is used for set-up (SRB 3). The specific second access network node is used for managing information of the second access network group; optionally, the specific second access network node is configured to allocate a DRB ID of the second access network group, allocate a serving cell index (servering cell index), allocate an LCID, a measurement ID, a measurement object ID, allocate a measurement report ID, and the specific second access network node is configured to generate a key and/or a management key for a second access network node within the second access network group, except for the specific second access network node.

The status and management of the at least two second access network nodes have been described correspondingly in the foregoing, and the bearers of the at least two second access network nodes are described below.

A bearer configuration diagram of a first access network node and a second access network node, as shown in fig. 12, the first configuration information is further used to indicate that a split (split) bearer includes at least three paths; wherein one of the at least three paths corresponds to the first access network node, and at least two of the at least three paths (leg) respectively correspond to different second access network nodes. Or, the first configuration information is further used for indicating that the split bearer includes two paths; the two paths respectively correspond to two different second access network nodes. Or, the first configuration information is further used to indicate an SCG bearer, where the PDCP entity and the radio link layer control protocol (Radio Link Control, RLC) entity of the SCG bearer correspond to different second access network nodes. Or, the first configuration information is further used for indicating that the split bearer includes two paths, a first path in the two paths corresponds to the first access network node, and a second path in the two paths corresponds to the second access network node. Alternatively, the first configuration information is further used to indicate a primary cell group (Master Cell Group, MCG) bearer, and the PDCP entity and RLC entity of the MCG bearer correspond to the first access network node. Or, the first configuration information is further used for indicating an SCG bearer, and the PDCP entity and the RLC entity of the SCG bearer are located in the same second access network node.

In the embodiment of the invention, the path comprises two states, namely a first state and a second state. When more than two paths are configured, one identification leg ID is configured for each path. The leg ID may be configured starting from 1, or the leg ID may be configured starting from 0. In the implementation, the terminal device updates the state of the path corresponding to the second access network node according to the second signaling sent by the network device. Optionally, the second signaling includes at least one of: PDCCH and MAC CE. The terminal equipment updates the state of the path into the first state or the second state through the bit value corresponding to the path identifier in the second signaling. For example, when a bit value corresponding to a path ID carried by the second signaling is a first value, the terminal device updates a state of the path to be a first state; and when the bit value corresponding to the path ID carried by the second signaling is a second value, the terminal equipment updates the state of the path to be a second state. Optionally, the first value is 0 and the second value is 1. In fig. 13 and 14, L1 to L8 identify the index numbers 1 to 8 of the paths to which the DRB IDs correspond; the bit value corresponding to Li characterizes the state of the path. Optionally, the number of bits identifying the DRB ID is flexibly configurable; as shown in fig. 13, the number of bits configured to identify the DRB ID is 6 bits, and as shown in fig. 14, the number of bits identifying the DRB ID is 5 bits. Thus, the bit number of the DRB ID can be flexibly configured according to the requirement, and the signaling overhead is reduced.

It should be noted that, in the embodiment of the present invention, the first access network Node is a Master Node (MN), and the second access network Node is a Secondary Node (SN). The first state of the second access network node is an activated state, the second state of the second access network node is a deactivated state, and the third state of the second access network node is a dormant state. The first state of the cell served by the second access network node is an activated state, the second state of the cell served by the second access network node is a deactivated state, and the third state of the cell served by the second access network node is a dorman state. The first state of the path is an activated state and the second state of the path is a deactivated state.
