Description
Technical Field
The present invention relates to the field of wireless technologies, and in particular, to a method, an apparatus, and a terminal for inter-system measurement.
Background
As a 3G subsequent evolution technology, lte (long Term evolution) has unique technical advantages of high data rate, low time delay, flexible bandwidth configuration, and the like. As 4G (lte) enters the commercial-scale phase, the fifth generation mobile communication (5G) facing 2020 and the future has become a global research and development hotspot. 5G can be regarded as a reengineering after LTE, i.e. a new technology that evolves and also introduces innovations.
Currently, 3GPP defines two schemes for 5G New Radio (NR) networking, namely, stand-alone networking (SA) and Non-stand-alone Networking (NSA). The non-independent networking refers to that a control plane (4G bears control signaling) is independently deployed by 4G, a user plane (5G and 4G bear user plane data) is jointly deployed by 5G and 4G or a user plane (only 5G bears user plane data) is independently deployed by 5G, and the independent networking refers to that a control plane and a user plane (5G bears control signaling and user plane data) are independently deployed by 5G. The independent networking mode of the 5G new air interface requires independent deployment of a 5G end-to-end network, new establishment of a base station and a core network, so that the 5G can work independently of 4G. The non-independent networking mode can depend on the existing 4G network, so that the requirement of part of operators on the 5G network is met.
For the non-independent networking mode, the terminal resides in 4G when in an idle state, and the 5G adjacent region is not measured. When a terminal needs to perform uplink/downlink data transmission, firstly, an RRC connection is established on 4G, a network issues a measurement control signaling carrying a 5G neighbor cell indication, the terminal starts to measure the 5G neighbor cell, when a measurement report condition is met, the terminal reports a measurement report, the network configures 4G +5G dual-connection according to a terminal report result, and at the moment, a 5G user plane is established.
Therefore, by adopting a 5G measurement mechanism in a non-independent networking mode, a terminal needs to establish RRC connection on 4G first and can start to measure 5G only after receiving a measurement control message issued by a network, and the network configures 4G +5G dual-connection after reporting a measurement report, so that the time delay for establishing the whole 5G user plane is long, and the terminal has a great disadvantage compared with the case that a 5G user plane can be directly established by a 5G independent networking and cannot meet the low-delay requirement of a 5G new service.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a heterogeneous system measuring method aiming at the problem that the time delay of the user plane establishment of a heterogeneous system is longer in the existing non-independent networking mode.
The inter-system measurement method according to the first embodiment of the present invention is applied to a terminal supporting dual connection between a first network and a second network, and as shown in fig. 1, the method includes:
s110, when the first network is resided in an idle state and the current data transmission is detected to be needed, the cell measurement of the second network is started.
Compared with the prior art that Radio Resource Control (RRC) connection must be established on a first network, and cell measurement of a second network is started after a measurement Control message issued by the network is received, the inter-system measurement method including the above steps starts measurement of the neighboring cell of the inter-system immediately when a terminal detects that data transmission is currently required, that is, uplink or downlink data transmission is required, so that compared with the prior art, cell measurement of the second network is performed in advance, thereby greatly shortening the user plane establishment delay of the inter-system and achieving the purpose of improving user experience.
Preferably, the inter-system measurement method according to the specific embodiment of the present invention is applied to a configuration of a first network and a second network that are jointly networked, where the configuration of the first network and the second network that are jointly networked may be a configuration in which a control plane is independently deployed for the first network (the local network in which the terminal is located), and a user plane is commonly deployed for the first network and the second network.
Specifically, the first network may be a 4G network, and the second network may be a 5G network.
When the first network is a 4G network and the second network is a 5G network, by adopting the inter-system measurement method of the embodiment of the invention, when the 4G and the 5G are networked together, the terminal resides in the 4G network in an idle state, only the adjacent cell of the system is measured, and when the terminal detects that uplink or downlink data transmission is required at present, the cell measurement of the 5G is started immediately. Therefore, compared with the prior art that the terminal needs to establish the RRC on the 4G first and can start the 5G after receiving the measurement control message sent by the network, the method of the embodiment of the invention can greatly shorten the establishment delay of the 5G user plane.
It can be understood that the inter-system measurement method according to the embodiment of the present invention is not limited to be applied to inter-system measurement of 4G and 5G co-networking.
In addition, the present invention further provides a inter-system measurement method of a second embodiment, as shown in fig. 2, in the second embodiment, the inter-system measurement method includes:
s210, obtaining a measurement control message for measuring the second network cell through a system broadcast message of a first network;
s220, when the first network is resided in an idle state and the current data transmission is detected to be needed, the cell measurement of the second network is started.
Specifically, in step S210, a measurement control message for second network cell measurement is issued in a system broadcast message of the first network; wherein the measurement control message includes: the terminal comprises a measurement object, a reporting configuration, a measurement identifier and other measurement configuration parameters, so that the terminal can be used for cell measurement of the second network.
Taking the first network as a 4G network and the second network as a 5G network as an example, the measurement control message for the 5G neighbor cell can be issued through a 4G cell system broadcast message, wherein a measurement object of the measurement control message is a 5G neighbor cell frequency point.
In step S220, when the first network resides in an idle state and it is detected that uplink data transmission is currently required, cell measurement on the second network is started; or, when the first network resides in an idle state and receives a paging message sent by the first network, determining that downlink data transmission is currently required, and starting cell measurement on a second network.
Preferably, step S220 may include:
and when the first network resides in an idle state, detecting that uplink data transmission is required currently and the data volume of the uplink buffer area is greater than the preset number, starting cell measurement of a second network.
By adopting the mode, for uplink data transmission, when the terminal detects that the data of the uplink buffer area is larger, the cell measurement of the second network is started.
In addition, preferably, step S220 may further include:
when the terminal is in an idle state and resides in a first network, and receives a paging message sent by a base station of the first network, wherein the paging message comprises indication information used for indicating the terminal to start cell measurement of a second network, the cell measurement of the second network is started.
Further preferably, when the base station of the first network detects that the downlink buffer data is large, the paging message sent to the terminal carries indication information for indicating the terminal to start cell measurement on the second network.
By adopting the above manner, the cell measurement of the second network can be started only when the uplink or downlink buffer data is large, so as to increase the flexibility of the inter-system measurement method according to the specific embodiment of the present invention.
In another aspect of the embodiment of the present invention, the measurement control message for the cell measurement of the second network may be sent to the terminal through a system broadcast message of the first network, or may be sent to the terminal through a paging message sent by a base station of the first network, so that the terminal may perform the cell measurement of the second network according to the received measurement control message.
In another aspect of the inter-system measurement method according to the second embodiment of the present invention, in step S220, while the step of starting cell measurement on the second network is executed or after step S220, the method further includes:
transmission of radio resource control, RRC, signaling of the first network is performed.
When the step of starting the cell measurement of the second network is executed and the transmission of the radio resource control RRC signaling of the first network is carried out, the terminal starts the dual radio mode when the cell measurement of the second network is carried out, namely the first network and the second network are simultaneously started and work in parallel, and at the moment, the measurement of the second network and the transmission of the RRC signaling of the first network can be simultaneously carried out.
Preferably, when the transmission of the radio resource control RRC signaling of the first network is performed after the step of starting the cell measurement of the second network, the transmission of the radio resource control RRC signaling of the first network is performed within a preset time after the cell measurement of the second network is started, so as to ensure the time delay.
For example, when the first network is a 4G network and the second network is a 5G network, the terminal starts the dual radio mode when measuring the 5G neighbor area, and the 5G and 4G start and operate in parallel at the same time, so that the measurement of the 5G and the transmission of the RRC signaling of the 4G can be performed at the same time.
By the mode, the effects of further reducing time delay and power consumption can be achieved.

wherein the measurement control message includes: the measurement method comprises the steps of measuring an object, reporting configuration, a measurement identifier and other measurement configuration parameters, wherein the object is a 5G adjacent cell frequency point, so that a terminal can perform 5G adjacent cell measurement according to a measurement control message.

s322, the terminal receives the paging message sent by the base station;
when one of the steps S321 and S322 is executed, step S330 is executed downwards;
s330, the terminal starts the measurement of the adjacent cell of 5G;
preferably, in step S321, when the terminal detects that the uplink buffer data is large, the cell measurement on the second network is started;
in step S322, the terminal receives a paging message sent by the base station, where the paging message includes indication information for indicating the terminal to start cell measurement for the second network, and executes step S330 according to the indication information; preferably, when the base station detects that the downlink buffer data is large, the paging message sent to the terminal carries indication information for indicating the terminal to start measurement of the 5G neighbor cell.
S340, the terminal establishes RRC connection;
s350, after the terminal enters an RRC connection state from an idle state, reporting a measurement report when a measurement reporting condition is met;
and S360, the terminal completes the 4G and 5G double-connection configuration.
Based on the above process, preferably, when the terminal performs the 5G neighbor cell measurement, the dual radio mode is turned on, the 4G and the 5G are simultaneously turned on and operate in parallel, and at this time, the 5G measurement and the RRC signaling transmission of the 4G can be simultaneously performed, so as to achieve the effect of further reducing the time delay and the power consumption.
