Fig. 3 is a flowchart of a second device moving method according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:

step S302, acquiring second mobile auxiliary information for indicating the movement of the relay device for device-to-device D2D communication with the terminal;

in step S304, a moving process is performed according to the acquired second mobility assistance information.

Through the above steps, by obtaining the second mobile auxiliary information for indicating the movement of the relay device, the problem that in the related art, in the D2D scenario, the power saving of the relay device in the moving process of the relay device is not fully considered is solved, and the effect of effectively saving power for the relay device in the moving process of the relay device in the D2D scenario is achieved.

Optionally, the access cell may include multiple types, for example, at least one of the following types: the mobile terminal comprises a broadband cell, a narrowband cell, a long term evolution system (LTE) cell, an evolved machine communication (eMTC) cell, a narrowband internet of things (NB-IOT), a fifth generation 5G cell and a 5G subsequent evolution cell (for example, a sixth generation 6G cell, a seventh generation 7G cell and the like).

When the second mobility assistance information indicating that the relay device performing D2D communication with the terminal moves is acquired, various interfaces may be used, and for example, the second mobility assistance information may be acquired through at least one of the following interfaces: a Uu opening; a PC5 interface; an 802.11 interface; a Bluetooth interface; and a Wifi interface.

When the second mobility assistance information indicating that the relay device performing D2D communication with the terminal moves is acquired, the second mobility assistance information may be acquired in various manners, for example, at least one of the following manners may be adopted: a Uu port unicast mode; uu port broadcast mode; a multicast/multicast single frequency network MBSFN broadcasting mode; single cell-point to multipoint SC-PTM broadcast.

Optionally, before obtaining the second mobility assistance information for instructing the relay device in D2D communication with the terminal to move, a request message for requesting to obtain the second mobility assistance information may also be sent, where the request message carries at least one of the following information for requesting to obtain the second mobility assistance information: a cell type; a cell bandwidth; deployment mode of cell.

Wherein, the deployment mode of the cell comprises at least one of the following modes: stand-alone mode; an In-band mode; guard-band approach.

When performing mobility processing according to the acquired second mobility assistance information, the mobility processing may be performed differently according to different contents carried by the second mobility assistance information. For example: under the condition that the second mobile auxiliary information carries the cell identification of the relay equipment access target cell, accessing the access target cell of the cell identification; for another example, when the second mobility assistance information does not carry the cell identifier of the relay device access target cell, one cell is selected from cells under the common base station of the relay device access target cell in D2D communication with the terminal for access.

In combination with the foregoing embodiment and the preferred embodiment, the terminal and the relay device are considered in combination, and in a D2D scenario, when the relay device and/or the terminal moves, how to enable the relay device and/or the terminal to timely sense a change of an access cell may be achieved, which may save power. In this embodiment, information such as a service characteristic, a mobility characteristic, a cell load, and mobility of the relay device of the terminal is comprehensively considered to assist the mobility processing of the relay device and/or the terminal, and the mobility processing of the relay device and/or the terminal is optimized for the mobility characteristic of the terminal and the relay device, so that the relay device and/or the terminal can timely sense a change of an access cell, and excessive measurement and control processing can be avoided, thereby achieving a purpose of saving power for the relay device and/or the terminal.

With the improvement of living standard and the development of science and technology, portable devices for human bodies are widely used. Portable devices such as heartbeat monitoring devices, pedometers, blood pressure monitors, smart bracelets, and the like, which are carried with them, are becoming more popular, and their numbers are increasing year by year. The portable device has the characteristics of low chip cost, small volume and small communication data volume, is generally used for monitoring, such as a heartbeat monitoring instrument and blood pressure monitoring, can periodically measure the information of the heartbeat frequency, the blood pressure and the like of a user, and then reports the information to a server, and a doctor or intelligent software at the server side judges whether the user is healthy or not. The server may also issue some information to the portable device through the network, for example, a software version update, or an action instruction such as an activation command or a deactivation command, and the portable device may receive the information and perform a corresponding action.

Among portable devices, Machine Type Communication (MTC) devices are a main Type of devices. Unlike conventional 3GPP services, MTC services have unique characteristics:

the amount of traffic data is very small. In the MTC service model currently counted in R13 by 3GPP, the MTC service reported periodically is 20 bytes. For example, the contents of monitoring data such as temperature, humidity, etc. are very few.

The cost is low. The MTC chip is generally low in cost, and the cost of the MTC chip is far lower than that of the intelligent terminal chip. This means that the processing of the terminal must be simplified as much as possible, and the terminal capabilities are much lower than those of conventional smart terminals.

The power consumption is low. Portable devices are typically battery powered and a 10 year life is expected, i.e. the batteries do not need to be replaced for many years.

Connection initiation is infrequent. Like the temperature measurement sensor, it may be reported only once in half an hour or ten minutes.

In order to better support portable equipment in a D2D scene, a FeD2D subject is introduced into 3GPP R14, and a reliable and high-quality communication service is specially provided for the portable equipment in a D2D scene. feD2D topic requirements propose the use of narrowband technology to enhance coverage for Remote devices in the D2D scenario; narrowband technologies that may be used include eMTC, NB-IOT, and the like.

In the related art, there are some problems with communication of portable devices in the D2D scenario.

In a portable scenario, the portable device moves with a person, and the moving frequency is similar to that of a conventional intelligent terminal.

Power saving is a necessary requirement for portable devices. However, the existing D2D protocol design of R13 is introduced for public safety equipment, and the design of mobility is not specially designed for power saving of portable equipment, which is not beneficial to power saving of portable equipment.

In order to save power for portable devices, 3GPP introduced narrowband technologies, including eMTC, narrowband Band-Internet of Things (NB-IOT) technology. In order to meet the harsh energy consumption requirement of the portable device, the 3GPP protocol simplifies the mobility processing of the portable device, and introduces a very long DRX cycle, so that the portable device may not need to perform neighbor cell measurement frequently, thereby saving power consumption.

However, the existing D2D design of 3GPP R13 was introduced for public safety equipment, and considered independently when considering the mobility of a Relay device (e.g., Relay UE) and a remote device (e.g., remote UE). The relay device and the remote device independently perform cell selection and handover, and repeat selection and PC5 interface reestablishment if a change is found. Since the remote device is in motion, it needs to perform cell reselection or handover continuously, which is not favorable for saving power of the terminal and also brings too much signaling overhead at the network side.

If the mobility policy of the current portable device is maintained, the remote device cannot timely sense the change of the accessed narrowband cell, so that data cannot be received and transmitted in time, and service experience is affected.

On the other hand, if the mobility policy in D2D of R13 is used, the portable device needs to continuously update or switch the cell, which is relatively power-consuming and cannot be used for a long time.

Since portable devices are generally battery powered and require very low power consumption to operate for long periods of time, special power saving designs are required to meet the power consumption requirements of portable terminal devices.

In order to optimize the mobile processing of the relay device and/or the portable device, in this embodiment, a method for mobile processing of the relay device and/or the portable device in a D2D scenario is provided, and includes: the mobility assistance information (the first mobility assistance information and the second mobility assistance information are respectively associated with the terminal and the relay device) is received, and mobility processing is performed based on the information.

Upon receiving the mobile assistance information, the relay device may obtain it from the base station and/or the portable device; the portable device may also be obtained from the base station and/or the relay device. When the relay device and/or the portable device obtain the mobile assistance information from the base station, the mobile assistance information may be obtained from a system broadcast message or proprietary signaling transmitted by the base station. Optionally, the relay device and/or the portable device may send a mobile assistance information acquisition request to the base station, where the mobile assistance information acquisition request may request to acquire at least one of the following information: requesting a cell type; requesting a bandwidth of a cell; requesting a deployment mode of a cell, wherein the deployment mode of the cell may include multiple types, for example, at least one of the following: stand-alone mode; an In-band mode; guard-band approach.

Performing mobility processing according to the mobility assistance information includes:

after receiving the mobile auxiliary information sent by the base station, the relay equipment carries out mobile processing; the relay device may send the mobility assistance information to the remote device;

after receiving the mobility assistance information sent by the base station, the remote device performs mobility processing, and the remote device may send the mobility assistance information to the relay device.

The above mentioned mobility processes may include, but are not limited to: determining whether the device initiates cell reselection to a new cell; it is decided whether the device initiates a handover to a new cell.

The following describes the movement processing performed by the relay device and the mobile device, respectively.

The remote equipment performs mobile processing according to the mobile auxiliary information, and the mobile processing comprises the following steps: the remote device may decide whether to move to a new target cell based on the mobility assistance information; and if the relay equipment is decided to move, selecting a proper cell to access in the cells under the common base station of the relay equipment access target cell. Cell selection may be based on remote device capabilities, and if the remote device supports only narrowband cells, e.g., eMTC cells, then there is a selection in the eMTC cell under the relay device access target cell site.

The relay device performing mobility processing according to the mobility assistance information includes: the relay equipment can judge whether to move to a new target cell according to the mobile auxiliary information; if it is decided to move, a suitable cell access is selected among cells under the remote device access target cell co-base station. Cell selection may be based on relay device capability, and if the relay device supports only wideband cells, e.g., LTE cells, then selection is made in LTE cells under the remote device access target cell site.

Through the above preferred embodiment, when the relay device and/or the portable device in the D2D scenario moves, the change of the access cell thereof can be timely sensed, so as to meet the requirements of Qos (e.g., delay) of the service, and the like, and the relay device and/or the portable device can also save power, so that excessive power consumption due to too frequent cell or neighboring cell measurement is avoided.

In the following, taking the relay device as the relay UE and the remote device as the remote UE as an example, the movement of the remote UE is taken as an example in conjunction with the D2D scenario.

The method for the relay UE to determine whether the access cell of the remote UE under the relay UE changes may include multiple methods, and before the determination method is described, the D2D scenario involved in this embodiment is described. Fig. 4 is a schematic diagram of an application mode of a D2D technology according to an embodiment of the invention 1, fig. 5 is a schematic diagram of an application mode of a D2D technology according to an embodiment of the invention 2, and fig. 6 is a schematic diagram of a typical co-sited deployment scenario according to an embodiment of the invention. Generally, wireless networks are co-sited to deploy narrowband cells and broadband, and a typical scenario is as follows: a small part of narrow-band low-frequency bandwidth is drawn out to provide wide coverage of a narrow-band cell and support small data services; most wideband low frequencies support LTE.

For the method for determining whether the access cell of the remote UE under the relay UE is changed, the base station may transmit the mobile assistance information in various manners, for example:

the method comprises the following steps: base station broadcast message notification mode:

the broadband cell broadcast information is added with the narrowband cell information deployed by the common station, including frequency points, cell ID and the like.

The relay UE can analyze the narrowband cell information from the current accessed broadband cell broadcast and judge whether the narrowband cell accessed by the remote UE is changed. If so, the remote UE is notified of its mobile-assisted information.

The method 2 comprises the following steps: and the base station configures the mode through a downlink air interface signaling. And the base station sends the narrowband cell information to the relay UE through a downlink air interface signaling.

After the relay UE accesses the broadband cell, an indication for acquiring narrowband information is carried in a Radio Resource Control (RRC) Request message.

And after receiving the information, the base station brings the narrow-band cell information into the RRC Setup message to the relay UE.

And the relay UE judges whether the narrow-band cell accessed to the base station is changed. If so, the remote UE is notified that its access cell has changed.

When the relay UE determines that the remote UE moves, the relay UE sends the mobility assistance information to the remote UE in various manners, for example:

for the remote UE which has established the PC5 connection, a newly added downlink PC5 message MovingInforNotify is sent, where the message carries the mobile assistance information to the remote UE.

For remote UEs that have not established a PC5 connection, the CELL ID announce message is used to broadcast narrowband CELL information for their co-sites, with the addition of mobile assistance information.

The remote UE performs corresponding mobility processing according to the mobility information sent by the relay UE, and the mobility processing comprises the following steps:

the relay UE receives the mobility information sent by the relay UE from the downlink PC5 signaling.

And if the newly added mobile auxiliary information indicates that the access cell of the relay UE is changed and a narrow-band cell suitable for the remote UE to access is arranged below the base station accessed by the relay UE, performing cell reselection and selecting a new narrow-band cell to access.

In the following, the relay UE is directed to move by combining the moving scenario, and the remote UE is directed to move by the relay UE.
