Description

Connection management method, first network equipment, terminal equipment and system

Technical Field

The present invention relates to information acquisition technologies in the field of communications, and in particular, to a connection management method, a first network device, a terminal device, and a system.

Background

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). Wherein, the non-independent networking refers to that a control plane (4G carries control signaling) is independently deployed by 4G, a user plane (5G and 4G carry user plane data) is jointly deployed by 5G and 4G, or a user plane (only 5G carries user plane data) is independently deployed by 5G; independent networking refers to a 5G independent deployment control plane and user plane (5G independently bears control signaling and user plane data), and an independent networking mode of a 5G new air interface requires independent deployment of a 5G end-to-end network, and new establishment of a base station and a core network, so that 5G can work independently of 4G.

The traditional inter-system connection state interoperation is a switching mode, specifically, after a terminal enters a 4G connection state, a 4G network issues all 5G neighbor cells, the terminal performs measurement, when the terminal moves to a 4G and 5G common coverage area and meets measurement reporting conditions, a 5G measurement report is triggered, and the network switches the terminal to the 5G neighbor cells according to the terminal measurement report.

However, for inter-system connection interoperation between 4G and 5G, if a conventional connection interoperation mechanism is adopted, the terminal measures all 5G neighboring cells, and switches to the 5G neighboring cells when the measurement reporting condition is met, there may be a case that the terminal is switched to the 5G cell and then the terminal cannot process a 5G signaling sent by the 5G cell, so that the terminal is abnormal in operation.

Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

The first embodiment,

An embodiment of the present invention provides a connection management method, applied to a first network device, as shown in fig. 1, including:

step 101: acquiring capability information of at least one adjacent cell; the capability information of the adjacent cell comprises that the adjacent cell is an independent networking cell or a non-independent networking cell;

step 102: acquiring the capability information of terminal equipment in a service cell managed by the terminal equipment; the capability information of the terminal equipment is at least used for indicating whether the terminal equipment supports independent networking and/or non-independent networking;

step 103: selecting at least one adjacent cell to be measured for the terminal equipment based on the capability information of the terminal equipment and the capability information of the at least one adjacent cell;

step 104: determining to switch the terminal equipment to a target cell in at least one adjacent cell to be measured or determine to configure dual connectivity for the terminal equipment based on a measurement report for the at least one adjacent cell to be measured reported by the terminal equipment; and the dual connection represents that the terminal equipment establishes connection with the serving cell and the target cell.

The embodiment of the invention mainly determines whether the terminal equipment needs to measure the adjacent cells of the different system or not according to whether the first network equipment supports independent networking and/or non-independent networking or not, and selects whether the terminal is switched to the different system or configures double connection of the system and the different system or not by the first network equipment according to the self capacity, the capacity of the adjacent cells of the different system and the terminal capacity.

It should be noted that the serving cell may support a first communication system, and the neighboring cell supports a second communication system; the first communication system is different from the second communication system, at least the transmission rate and the communication bandwidth of the second communication system are higher than those of the first communication system, and the transmission delay of the second communication system is lower than that of the second communication system.

Specifically, the first communication standard may be provided by a 4G communication network, and the second communication standard may be provided by a 5G communication network. Further, the serving cell may be a serving cell in a 4G communication network; at least part of the at least one neighboring cell supports the second communication system, that is, there may be a part of the at least one neighboring cell being 4G cells, and another part of the at least one neighboring cell being 5G cells.

In addition, the foregoing is only one case, and there may be another case, where the serving cell and the neighboring cell are both cells of the same communication system, for example, both the serving cell and the neighboring cell may be 5G cells, and then the capabilities of the serving cell and the neighboring cell may be different, for example, the current serving cell is a cell supporting independent networking, and some neighboring cells are cells supporting non-independent networking.

In this embodiment, before step 101 is executed, information of an adjacent cell may also be obtained in advance, and specific manners include the following two ways:

storing a neighbor cell list; the adjacent cell list at least comprises at least one adjacent cell with a different communication system from the service cell and the capability information of each adjacent cell;

or,

and acquiring the capability information of at least one adjacent cell from a second network device corresponding to the at least one adjacent cell.

The stored neighboring cell list may be list information preset in the first network device according to an actual situation, and the specific preset method is not described herein again.

The manner of acquiring the capability information of at least one neighboring cell may be that the first network device sends a cell capability acquisition request to the second network device through a communication interface with the second network device of the neighboring cell, and then receives the capability information of the neighboring cell sent by the second network device.

The following describes, with reference to fig. 2, selection of the capability information of the neighboring cell and the capability information of the terminal device, the neighboring cell to be measured, and the manner in which the terminal device accesses the target cell:

scene one,

The selecting at least one neighboring cell to be measured for the terminal device based on the capability information of the terminal device and the capability information of the at least one neighboring cell includes:

and when the capability information of the terminal equipment indicates that the terminal equipment at least supports independent networking, selecting an adjacent cell at least supporting independent networking from at least one adjacent cell as a to-be-measured adjacent cell based on the capability information of the at least one adjacent cell.

In conjunction with fig. 2, it is assumed that the neighboring cells are 5G neighboring cells, wherein there are different types of neighboring cells that support NSA only, SA only, NAS and SA with NSA first, and NSA and SA with SA first; when the terminal device only supports SA, the remaining 5G neighboring cells supporting at least SA may be selected as the neighboring cells to be measured of the terminal device, except that the neighboring cells supporting only NSA do not perform measurement.

Correspondingly, the determining to switch the terminal device to a target cell in the at least one neighboring cell to be measured or determine to configure dual connectivity for the terminal device based on the measurement report for the at least one neighboring cell to be measured reported by the terminal device includes:

and selecting a target cell for the terminal equipment from the at least one adjacent cell to be measured based on the measurement report which is reported by the terminal equipment and aims at the at least one adjacent cell to be measured, and determining to switch the terminal equipment to the target cell.

That is, when the 5G neighbor cell and the terminal device both support the SA, it may be controlled such that the terminal device directly switches to the 5G target cell.

Scene two,

and when the capability information of the terminal equipment represents that the terminal equipment only supports non-independent networking, selecting an adjacent cell only supporting non-independent networking from at least one adjacent cell as an adjacent cell to be measured based on the capability information of the at least one adjacent cell.

Referring to fig. 2, when the terminal device only supports NSA, other 5G neighboring cells may be selected as the neighboring cells to be measured, except for the 5G neighboring cells only supporting SA.

selecting a target cell for the terminal equipment from the at least one adjacent cell to be measured based on a measurement report which is reported by the terminal equipment and aims at the at least one adjacent cell to be measured, and determining to configure dual connection with the target cell and the serving cell for the terminal equipment.

That is, in the case of a terminal device supporting only NSA, the target cell is also a cell capable of supporting NSA, and then, when performing handover, the terminal device is configured to establish dual connectivity between the serving cell and the target cell.

Scene three,

When the capability information of the terminal equipment indicates that the terminal equipment at least supports independent networking, if a target cell supports independent networking or simultaneously supports dependent networking and independent networking, determining to switch the terminal equipment to the target cell;

when the capability information of the terminal equipment indicates that the terminal equipment only supports independent networking, if a target cell supports simultaneous support of dependent networking and independent networking, determining to switch the terminal equipment to the target cell; otherwise, determining to configure dual connection for the terminal equipment.

Referring to fig. 2, the terminal device supports both NSA and SA, and whether NSA is preferred or SA is wired, as long as it is determined that the target cell for handover supports only SA, or the target cell supports both NSA and SA with SA being preferred, it is determined that the terminal device directly switches to the target cell;

otherwise, determining that the terminal equipment needs to establish double connection.

In this embodiment, mainly taking the interoperation between the 4G and 5G connections as an example, the key process is as follows:

the 5G neighbor list stored by the network side of the 1.4G cell contains the 5G neighbor capability, that is, the 5G neighbor only supports NSA indication, only supports SA indication, supports NSA + SA indication (including SA priority or NSA priority),

2. the terminal initiates RRC connection establishment in the 4G cell, reports the capability that only NSA is supported, only SA is supported, and simultaneously NSA + SA (SA priority or NSA priority) is supported,

and the 3.4G cell selectively issues 5G neighbor cell measurement according to the terminal capability, the self capability and the capability of the 5G neighbor cell, and when the terminal reports a measurement report, the 3.4G cell selectively switches or configures the double connection according to the terminal capability and the indication of the 5G neighbor cell.

Wherein, regarding the 5G neighbor capability, the 5G neighbor list may be saved, including the 5G neighbor capability; or the 4G cell and the 5G cell carry out interface interaction, and the 5G cell transmits the own capability to the 4G cell; the 4G cell can also transmit the terminal capability to the 5G cell, and the 5G cell determines double connection or switching according to the capability and the terminal capability of the 5G cell and sends the double connection or switching to the 4G cell and then is executed by the 4G cell.

In particular, if the 4G cell does not support NSA,

1. the rule for issuing 5G neighbor measurement is as follows:

1) if the terminal at least supports the SA and the 5G adjacent cell at least supports the SA, the 4G cell will issue the 5G adjacent cell measurement, when the terminal reports the measurement report, the terminal is switched to the 5G adjacent cell,

2) and for other cases, not sending the 5G neighbor measurement.

2. And when the terminal moves to a 4G and 5G common coverage area, reporting a 5G measurement report, and switching the terminal to a 5G adjacent cell by the network according to the terminal measurement report.

If the terminal only supports NSA, the rule for issuing 5G neighbor measurement is as follows:

1) if the terminal only supports NSA and the 5G neighbor only supports SA, or if the terminal only supports SA and the 5G neighbor only supports NSA, the network does not issue 5G neighbor measurements,

2) and for other conditions, the network issues 5G neighbor measurement.

2. When the terminal moves to a 4G and 5G common coverage area, reporting a 5G measurement report, and the 4G cell issues a signaling for establishing the dual-connection bearer or a switching signaling according to the terminal capability and the information indication of the 5G adjacent cell:

1) if the 5G neighbor supports SA, or supports NSA + SA (SA first), and the terminal supports at least SA, a handover is triggered,

2) if the 5G neighbor supports NSA + SA (NSA-first), and the terminal supports only SA, handover is also triggered,

3) for other cases, the network configures dual connectivity.

For the inter-system connection state interoperation of 4G and 5G, if a traditional connection state interoperation mechanism is adopted, the terminal measures all 5G adjacent cells, and switches to the 5G adjacent cells when the measurement reporting condition is met, but if the 5G adjacent cells are in an NSA mode, the terminal only supports an SA mode, the terminal works abnormally due to the fact that the 4G independently bears control signaling and the 5G does not bear the control signaling, and the 5G cell cannot process the 5G signaling sent by the terminal after the terminal is switched to the 5G cell; if the 5G adjacent cell is in the SA mode, the terminal only supports the NSA mode, and the terminal is switched to the 5G cell and then works abnormally due to the fact that the terminal cannot process the 5G signaling sent by the 5G cell.

In this embodiment, based on the capabilities of different neighboring cells and the capability of the terminal device, the neighboring cell to be measured that matches the capability of the terminal device is selected, so that the terminal device can measure only the matching neighboring cell to be measured, and finally determine the handover mode. Therefore, unnecessary cell measurement and switching can be avoided, terminal power consumption and network overhead are saved, and user experience is effectively improved.

Example II,

The embodiment provides a connection management method, which is applied to a terminal device, and as shown in fig. 3, the method includes:

step 301: sending capability information to a serving cell of the mobile terminal; the capability information of the terminal equipment is at least used for indicating whether the terminal equipment supports independent networking and/or non-independent networking;

step 302: receiving at least one adjacent cell to be measured distributed by the serving cell, measuring the adjacent cell to be measured to obtain a measurement report, and sending the measurement report to the serving cell;

step 303: receiving a switching instruction sent by the serving cell, and switching to a target cell in the at least one adjacent cell to be measured or establishing dual connectivity with the serving cell and the target cell based on the switching instruction.

In this embodiment, the serving cell and the neighboring cell to be measured are both cells of the same communication system, for example, may be both 5G cells, and then there may be a case where the capabilities of the serving cell and the neighboring cell to be measured are different, for example, the current serving cell is a cell supporting independent networking, and there are some neighboring cells that are cells supporting non-independent networking.

There is another case where: the serving cell supports a first communication system; at least part of the at least one adjacent cell to be measured supports a second communication system;

the first communication system is different from the second communication system, at least the transmission rate and the communication bandwidth of the second communication system are higher than those of the first communication system, and the transmission delay of the second communication system is lower than that of the second communication system.

Specifically, the first communication standard may be provided by a 4G communication network, and the second communication standard may be provided by a 5G communication network. Further, the serving cell may be a serving cell in a 4G communication network; at least part of the at least one neighboring cell to be measured supports the second communication system, that is, there may be a part of cells of 4G and another part of cells of 5G in the at least one neighboring cell to be measured.

In particular, if the 4G cell does not support NSA,

1. the rule for issuing 5G neighbor measurement is as follows:

2) and for other cases, not sending the 5G neighbor measurement.

2) and for other conditions, the network issues 5G neighbor measurement.

3) for other cases, the network configures dual connectivity.
