Description

Information indicating, receiving and sending method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information indicating, receiving, and sending method, a network device, and a terminal.

Background

A User Equipment (UE) can simultaneously transmit and receive data to and from two base stations, and this manner is called Dual Connectivity (DC). Wherein, only one base station is responsible for interacting with the core network control plane entity, the base station is a main base station, and the other base station is an auxiliary base station. The main base station has one cell which is the main cell of the UE and the other cells which are the secondary cells. The Cell Group of the Master base station is a Master Cell Group (MCG), and the Cell Group of the secondary base station is a Secondary Cell Group (SCG).

Currently, the UE performs dual connectivity in the following manner:

the UE firstly establishes connection with the MCG through an initial access process; the MCG determines SCG for DC based on the measurement report result of the UE; the MCG sends a DC request to the SCG through information interaction between the base stations, and indicates that the SCG has UE to perform DC; after the SCG receives the request, the MCG is informed to approve DC through information interaction between the base stations; the MCG tells the UE to carry out the SCG ID of the DC; the UE performs initial access with the SCG. The main purpose of the UE performing the initial access procedure to the SCG is: the base station informs the UE of the timing advance TA (timing advance), and enables the base station and the UE to know the C-RNTI of the UE.

In the above process, the UE first establishes a connection with the MCG, and then performs a series of processes to perform initial access with the SCG, so as to implement dual connectivity. That is, in the prior art, if the UE needs to perform dual connectivity, the UE needs to perform an initial access process with the MCG and the SCG in sequence, which is tedious in connection process, long in time delay, and low in efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of an information indicating method provided in an embodiment of the present invention, and is applied to a main network device, as shown in fig. 1, the information indicating method includes the following steps:

step 101, indicating at least one of first identification information and a first Timing Advance (TA) to the terminal, wherein the first identification information is allocated to the terminal by an auxiliary network device; the first TA corresponds to the secondary network device.

In this step, the first Identifier information may be a Cell Radio Network Temporary Identifier (C-RNTI), and the C-RNTI is allocated to the terminal by the auxiliary Network device; the first Timing Advance (TA for short) corresponds to the secondary network device. The first identification information and the first TA are sent by the secondary network device to the primary network device.

The Cell Group of the Master network device is a Master Cell Group (MCG for short), the Cell Group of the secondary network device is a secondary Cell Group (SCG for short), and the terminal may be UE.

After acquiring at least one of the first identification information and the first TA, the terminal does not need to perform an initial access procedure with the secondary network device, but directly monitors information of the secondary network device.

In the embodiment of the invention, at least one of first identification information and a first Time Advance (TA) is indicated to the terminal, and the first identification information is distributed to the terminal by secondary network equipment; the first TA corresponds to the secondary network device. The main network device can indicate at least one of the first identification information and the first TA to the terminal, so that the terminal can directly monitor the information of the auxiliary network device without performing initial access with the auxiliary network device, i.e., the terminal does not need to perform initial access with the auxiliary network device, and can perform double connection or multiple connection, thereby simplifying the connection process and improving the connection efficiency.

From another perspective, no matter in a display mode or an implicit mode, the terminal can acquire information which can be acquired only by interaction with the auxiliary network device without interaction with the auxiliary network device, so that the connection process is simplified, and the connection efficiency is improved.

Optionally, the indicating at least one of the first identification information and the first timing advance TA to the terminal includes: indicated by implicit means or explicit means;

indicating at least one of first identification information and a first Timing Advance (TA) to the terminal in an implicit manner or an explicit manner, including:

indicating a first TA to the terminal in an implicit mode;

the step of implicitly indicating the first timing advance TA to the terminal specifically includes:

implicitly indicating that the first TA is the same as a second TA corresponding to the primary network device through the first identification information; or sending indication information, implicitly indicating that the first TA is the same as a second TA, wherein the second TA corresponds to the primary network device.

In this embodiment, when the master network device indicates at least one of the first identification information and the first timing advance TA to the terminal, the master network device may indicate at least one of the first identification information and the first TA to the terminal in an implicit manner, or may indicate at least one of the first identification information and the first TA to the terminal in a display manner.

The first TA is implicitly indicated to be the same as the second TA by the first identification information, which may be understood as that when the primary network device sends the first identification information to the UE, the primary network device indicates that the TA corresponding to the secondary network device is the same as the TA corresponding to the primary network device, and the UE may use the known TA corresponding to the primary network device as the TA corresponding to the secondary network device to perform subsequent processing.

In the above manner, the main network device only sends the first identification information to the terminal, which indicates that the first TA is the same as the second TA, thereby saving signaling overhead. For example, when the first TA is the same as the second TA, the primary network device only sends the first identification information to the terminal, and when the terminal receives the first identification information, the terminal may not only obtain the first identification information, but also know that the first TA is the same as the second TA.

In addition, the step of implicitly indicating the first TA to the terminal may further be: and sending indication information to the terminal. When the terminal receives the indication information, it can know that the first TA is the same as the second TA, and in this case, the terminal uses the second TA to communicate with the secondary network device.

The above-described approach may be applied to scenarios in which the primary network device and the secondary network device are co-located, but may also be applied to other scenarios.

The condition that the first TA is the same as the second TA may be that the primary network device compares the first TA with the second TA of the primary network device after receiving the first TA sent by the secondary network device, and confirms that the first TA is the same as the second TA; or, the first TA may be the same as the second TA when the primary network device receives an implicit indication sent by the secondary network device; or the primary network device is co-sited with the secondary network device. At this time, the secondary network device has the same TA as the primary network device. When determining that the first TA is the same as the second TA, the primary network device may implicitly indicate that the first TA is the same as the second TA by sending the first identification information to the terminal, or implicitly indicate that the first TA is the same as the second TA by sending the indication information to the terminal. In this case, the terminal may communicate with the secondary network device using the second TA of the primary network device.

Optionally, the first identifier information is transmitted through an RRC configuration message carrying identifier information of the secondary network device, or the indication information is transmitted through an RRC configuration message carrying identifier information of the secondary network device, or the first TA displaying the indication is transmitted through an RRC configuration message carrying identifier information of the secondary network device.

When the primary network device sends the first identification information to the terminal, the first identification information is transmitted through a Radio Resource Control (RRC) configuration message, where the RRC configuration message carries identification information of the secondary network device.

When the primary network device implicitly indicates that the first TA is the same as the second TA by sending the indication information, the indication information is transmitted through an RRC configuration message, where the RRC configuration message carries identification information of the secondary network device.

When the main network device displays and indicates the first TA to the terminal, the first TA is transmitted through an RRC configuration message, and the RRC configuration message carries the identification information of the auxiliary network device.

Optionally, the indicating at least one of the first identification information and the first timing advance TA to the terminal in an implicit manner or an explicit manner includes:

indicating first identification information to the terminal in an implicit mode;

before the first identification information is implicitly indicated to the terminal, the method further includes:

sending a node addition request message to the auxiliary network equipment, indicating the auxiliary network equipment, and returning the first identification information under the condition of agreeing to establish double connection or multi-connection with the terminal;

and receiving a node increase request confirmation message which is sent by the auxiliary network equipment and carries the first identification information.

Specifically, the main network device indicates the first identification information to the terminal, and may indicate in an explicit manner or in an implicit manner. And when the indication is carried out in an explicit mode, the first identification information is transmitted through an RRC configuration message carrying the identification information of the secondary network equipment. When the implicit indication is adopted, the implicit indication message sent by the main network device to the terminal does not carry actual first identification information, and at this time, the terminal can obtain the actual first identification information according to the implicit indication message through a mapping relation obtained in advance. For example, in the mapping relationship, the implicit indication message a corresponds to B (B is a piece of first identification information), and if the implicit indication message is a, the terminal obtains the implicit indication message a, and then knows that the actual first identification information is B according to the mapping relationship.

Because the first identification information is sent to the main network device by the auxiliary network device, before the main network device sends the first identification information to the terminal, the main network device further needs to request the auxiliary network device to acquire the first identification information, that is: and the main network equipment sends a node adding request message to the auxiliary network equipment to indicate the auxiliary network equipment to return the first identification information under the condition of agreeing to establish double connection or multi-connection with the terminal.

The above-mentioned multiple connections are to be understood as three or more connections. The main network equipment sends a node adding request message to the auxiliary network equipment, wherein the node adding request message is used for indicating the auxiliary network equipment to distribute first identification information to the terminal under the condition that the auxiliary network equipment agrees to establish double connection or multi-connection with the terminal, and the first identification information is returned. And if the auxiliary network equipment agrees to establish double connection or multi-connection with the terminal, the auxiliary network equipment returns a node addition request confirmation message to the main network equipment, wherein the node addition request confirmation message carries the first identification information.

And after receiving the node addition request confirmation message, the main network equipment indicates the first identification information to the terminal in an implicit mode. After receiving the first identification information, the terminal does not perform initial access with the auxiliary network device any more, and can directly monitor the information of the auxiliary network device, namely, the terminal does not need to perform initial access flow with the auxiliary network device any more, and can perform double connection or multiple connections, thereby simplifying the connection process and improving the connection efficiency.

Referring to fig. 2, fig. 2 is a flowchart of an information receiving method according to an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 2, the information receiving method includes the following steps:

step 201, acquiring at least one of first identification information and a first time advance TA indicated by a master network device; the first identification information is distributed to the terminal by the auxiliary network equipment; the first TA corresponds to a secondary network device.

In this step, the first identification information may be a C-RNTI, which is allocated by the secondary network device to the terminal; the first Timing Advance (TA for short) corresponds to the secondary network device. The first identification information and the first TA are sent by the secondary network device to the primary network device.

After acquiring at least one of the first identification information and the first TA, the terminal does not perform initial access with the secondary network device, but directly monitors the information of the secondary network device.

In the embodiment of the invention, at least one of first identification information and a first time advance TA which are indicated by a master network device in an implicit mode or an explicit mode is obtained; the first identification information is distributed to the terminal by the auxiliary network equipment; the first TA corresponds to a secondary network device. Through obtaining the first identification information that main network equipment instructed and at least one in the first TA for the terminal can not need to carry out initial access with assisting network equipment, and directly can monitor assisting network equipment's information, and the terminal need not carry out initial access flow with assisting network equipment again promptly, alright carry out double connection or many connections, simplified the connection process, improved connection efficiency.

Optionally, the obtaining at least one of the first identification information and the first timing advance TA indicated by the primary network device includes: acquiring at least one of first identification information and a first time advance TA which are indicated by main network equipment in an implicit mode or an explicit mode;

acquiring at least one of first identification information and a first Timing Advance (TA) indicated by a master network device in an implicit mode or an explicit mode, including:

acquiring a first TA indicated by main network equipment in an implicit mode;

the obtaining of the first time advance TA indicated by the master network device in an implicit manner specifically includes:

determining that the first TA is the same as the second TA, which corresponds to the primary network device, when the primary network device indicates the first identification information; or determining that the first TA is the same as the second TA when receiving indication information implicitly indicating that the first TA is the same as the second TA sent by the primary network device, where the second TA corresponds to the primary network device.

In this embodiment, the master network device may indicate at least one of the first identification information and the first TA to the terminal in an implicit manner, and the master network device may also indicate at least one of the first identification information and the first TA to the terminal in a display manner.

The primary network device implicitly indicates, by the first identification information, that the first TA is the same as the second TA. For example, when the first TA is the same as the second TA, the primary network device only sends the first identification information to the terminal, and when the terminal receives the first identification information, the terminal may not only obtain the first identification information, but also know that the first TA is the same as the second TA.

In addition, the master network device may indicate, to the terminal in an implicit manner, that the first TA is further: and sending the indication information that the first TA is the same as the second TA to the terminal, and the terminal can know that the first TA is the same as the second TA by receiving the indication information. For example, when the first TA is the same as the second TA, the primary network device transmits instruction information to the terminal, and when the terminal receives the instruction information, the terminal recognizes that the first TA is the same as the second TA.

The condition that the first TA is the same as the second TA may be that the primary network device compares the first TA with the second TA of the primary network device after receiving the first TA sent by the secondary network device, and confirms that the first TA is the same as the second TA; or, the first TA may be the same as the second TA when the primary network device receives an implicit indication sent by the secondary network device; or, the primary network device and the secondary network device are co-sited, in which case the secondary network device and the primary network device have the same TA. When determining that the first TA is the same as the second TA, the primary network device may implicitly indicate that the first TA is the same as the second TA by sending the first identification information to the terminal, or implicitly indicate that the first TA is the same as the second TA by sending the indication information to the terminal. In this case, the terminal may communicate with the secondary network device using the second TA of the primary network device.

Optionally, the first identifier information is transmitted through an RRC configuration message carrying identifier information of the secondary network device, or the indication information is transmitted through an RRC configuration message carrying identifier information of the secondary network device, or the first TA sent in an explicit manner is transmitted through an RRC configuration message carrying identifier information of the secondary network device.

Specifically, the primary network device may send the first identifier information, the indication information, or the first TA to the terminal through an RRC configuration message, where the RRC configuration message carries the identifier information of the secondary network device. For example, when the primary network device sends the first identification information to the terminal, the first identification information may be transmitted through an RRC configuration message; when the main network equipment implicitly indicates that the first TA is the same as the second TA by sending the indication information, the indication information is transmitted through an RRC configuration message; when the primary network device displays an indication of the first TA to the terminal, the first TA is transmitted through an RRC configuration message.

The first identification information may be a C-RNTI, which is allocated by the secondary network device to the terminal. The first identification information may also be other information allocated by the secondary network device to the terminal.

The primary network device receives at least one of the first identification information and the first time advance TA sent by the secondary network device, so as to be used in subsequent steps, for example, indicate at least one of the first identification information and the first time advance TA to the terminal in an implicit manner or an explicit manner, so that the terminal can directly monitor the information of the secondary network device without performing initial access with the secondary network device, that is, the terminal does not need to perform an initial access procedure with the secondary network device, and can perform dual connection or multiple connections, thereby simplifying a connection process and improving connection efficiency.

The main network device can use at least one of the received first identification information and the first time advance TA for the connection between the terminal and the auxiliary network device, so that the terminal can directly monitor the information of the auxiliary network device without performing initial access with the auxiliary network device, namely, the terminal does not need to perform initial access flow with the auxiliary network device, and can perform double connection or multiple connections, thereby simplifying the connection process and improving the connection efficiency.

The node addition request acknowledgement message carries at least one of the first identification information and the first TA.

The master network device indicates at least one of the first identification information and the first TA to the terminal in an implicit manner or an explicit manner after receiving the node addition request acknowledgement message. After receiving at least one of the first identification information and the first TA, the terminal does not perform initial access with the auxiliary network device any more, and can directly monitor information of the auxiliary network device, that is, the terminal does not need to perform initial access with the auxiliary network device any more, and can perform double connection or multiple connections, thereby simplifying the connection process and improving the connection efficiency.

step 401, sending at least one of first identification information and a first timing advance TA to a primary network device, where the first identification information is allocated to the terminal by the secondary network device, and the first TA corresponds to the secondary network device.

In this step, the first identification information is allocated to the terminal by the secondary network device; the first TA corresponds to the secondary network device. The first identification information and the first TA are sent by the secondary network device to the primary network device. The first identification information may be a C-RNTI, which is allocated by the secondary network device to the terminal.

In this embodiment, the secondary network device sends at least one of first identification information and a first timing advance TA to the primary network device, where the first identification information is allocated to the terminal by the secondary network device, and the first TA corresponds to the secondary network device. Therefore, the main network device can use at least one of the received first identification information and the first time advance TA for the connection between the terminal and the auxiliary network device, so that the terminal can directly monitor the information of the auxiliary network device without performing initial access with the auxiliary network device, namely, the terminal can perform double connection or multiple connections without performing initial access flow with the auxiliary network device, the connection process is simplified, and the connection efficiency is improved.

The terminal is UE, the MCG represents main network equipment, and the SCG represents auxiliary network equipment. When the MCG and the SCG share the same site, the UE does not need to initially access the SCG, and the TA of the MCG is used for the SCG. However, the C-RNTI in the SCG cell working needs to be obtained through interaction between the MCG and the SCG base station, and the steps are as follows:

step 11, accessing a main cell, namely establishing connection between the UE and an MCG (Master cell group);

step 12, sending the measurement results of other cells, that is, the UE informs the MCG of the measurement results of other cells, for example, RSRP and other information, so that the MCG determines the SCG for performing dual connectivity based on the measurement report result of the UE;

step 13, the MCG (i.e. the main network device) requests the SCG (i.e. the auxiliary network device), a certain UE (i.e. the terminal) needs to perform DC and informs the UE of information such as ID and UE capability, and requests the SCG to allocate to the UE a C-RNTI, i.e. the MCG sends a DC request (i.e. a node addition request message) to the SCG through information interaction between base stations, informs the SCG that there is a UE to perform DC and informs the UE of information such as ID and UE capability, and in addition, the MCG also requests the SCG to allocate to the UE a C-RNTI;

step 14, the SCG (i.e. the secondary network device) informs the MCG (i.e. the primary network device) of the C-RNTI allocated for the UE (i.e. the terminal) by requesting and informing, that is, after the SCG receives the DC request, the MCG agrees to perform DC through information interaction between the base stations; and informing the MCG of the C-RNTI of the UE; SCG starts timing;

step 15, informing at least one of TA information and C-RNTI information of the terminal, namely, informing the UE of the SCG ID (namely the identification information of the auxiliary network equipment) of the DC by the MCG, and informing at least one of the TA information and the C-RNTI information;

after the above process, the UE can directly monitor the SCG information without performing initial access with the SCG; the SCG starts transmitting information to the UE after a set time (i.e., the timer set by the SCG expires) is exceeded.

The MCG may inform the UE of one of the following information: C-RNTI information; C-RNTI information and co-site information; C-RNTI information and TA information; C-RNTI information, TA information and co-site information. After receiving any of the above information, the UE does not perform initial access with the SCG any more.

If the UE receives the C-RNTI information and the TA information, the UE uses the TA for the SCG cell;

and if the UE receives the C-RNTI information notified by the MCG or the C-RNTI information and the co-site information notified by the MCG, namely the UE does not receive TA information, the UE uses the TA of the MCG for the SCG cell.
