Communication between the cellular telephone and the smart home device is accomplished without relaying communication signals through the base station.

Currently, certain communication traffic information already supports fixed, long-term slicing (sliding). However, as communication technologies evolve, some communication systems also need to introduce new slices for providing corresponding slice services to terminal devices, which may be temporary, small-range (e.g., ad-hoc slices). However, it is not clear how to indicate the information of such a slice (i.e. introducing a new slice) to ensure that the terminal device can obtain the information of the slice and use the slice for corresponding traffic transmission.

In order to solve the above technical problems, embodiments of the present application are described in detail below with reference to fig. 2 to 6.

Fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present application. It should be understood that fig. 2 illustrates steps or operations of a communication method, but these steps or operations are merely examples, and embodiments of the present application may perform other operations or variations of the operations in fig. 2, or not all steps need to be performed, or the steps may be performed in other orders. The method 200 shown in fig. 2 may include step S220, specifically as follows:

s220, the network equipment sends the first information to the terminal equipment.

Wherein the first information comprises information of a target slice supported or to be supported by the network device. Alternatively, the target slice supported by the network device may refer to a target slice that the network device has already supported, and the target slice that the network device will support may refer to a target slice that the network device supports at some later time or period.

Alternatively, the first information may be carried in a system information block (system information block, SIB) message.

Optionally, the first information may also be carried in a radio resource control (radio resource control, RRC) message. For example, the RRC message may be an RRC reconfiguration message or an RRC release (RRC release) message. Alternatively, in case the first information is an RRC release message, the terminal device may be in an idle state.

In some embodiments, the network device may send an RRC message to the terminal device if the first condition is met. Wherein the first condition may include at least one of: the network device knows the information of the target slice, the target slice is available, the information of the target slice is about to be available, and/or the terminal device reports support for the target slice.

Alternatively, the target slice may be a temporarily deployed slice, or a temporarily available slice. Alternatively, the target slice may be a temporary, small range slice. For example, the target slice may be an ad-hoc slice.

Optionally, the target slice may include a slice corresponding to a cell in which the terminal device is currently located (i.e., a slice of the local area); alternatively, the target slice may also include a slice corresponding to a cell adjacent to the cell in which the current cell is located (i.e., a slice of an adjacent cell); or the target slice may also include a slice corresponding to the cell in which the terminal device is currently located and a slice corresponding to a cell adjacent to the cell in which the terminal device is currently located. Optionally, the target slice may include a slice corresponding to the current frequency point and/or a slice corresponding to other frequency points.

Accordingly, the information of the target slice may include: the method comprises the steps of obtaining slice information of a local area, slice information of a neighboring area, slice information corresponding to a current frequency point and/or slice information corresponding to other frequency points.

In some embodiments, the information of the target slice may include at least one of: the method comprises the steps of identifying a target slice, identifying a slice group where the target slice is located, identifying a frequency point corresponding to the target slice, prioritizing the frequency point corresponding to the target slice, serving area of the target slice and available time of the target slice.

In some embodiments, the information of the target slice may always include at least one of: the frequency point corresponding to the target slice, the frequency point priority corresponding to the target slice, the service area of the target slice and/or the available time of the target slice. Further, the information of the target slice may further include an identification of the target slice and/or an identification of a slice group in which the target slice is located.

Optionally, when the target slice is available, the first information may include information of the target slice, that is, in the case where the target slice is available, there may be information of the target slice in the first information; and/or, when the target slice is not available, the first information may not include information of the target slice, i.e., in the case where the target slice is not available, there may be no information of the target slice in the first information.

Prior to S220, the method 200 may further include step S210, specifically as follows:

and S210, the network equipment sends second information to the terminal equipment.

Wherein the second information is used to indicate at least one of information of the target slice, system information (system information, SI) changes for the target slice, and a target slice supported or to be supported by the network device.

In some embodiments, the terminal device may receive the first information according to an indication of the second information.

Alternatively, in the case where the second information indicates information of the target slice, the second information and the first information may be the same information. That is, the second information may directly carry the information of the target slice, and in this case, the second information and the first information are the same information.

Alternatively, the system information change for the target slice may refer to: system information needs to be changed for, or triggered by, the target slice. For example, after the system information is changed, the SIB message including the first information may be carried.

Alternatively, the second information may instruct the terminal device to acquire the target slice (or information of the target slice) at a predetermined or instructed time period (or time).

For example, the second information may be used to indicate at least one of:

the terminal equipment acquires the target slice in the current system information change period; the terminal equipment acquires the target slice in the next system information change period; the terminal equipment acquires changed system information corresponding to the target slice in a current system information change period; and/or the terminal equipment acquires the changed system information corresponding to the target slice in the next system information change period.

In some embodiments, the network device may send the second information to the terminal device through paging (paging) downlink control information (downlink control information, DCI). For example, the network device may send paging DCI in which the second information is carried; accordingly, the terminal device may monitor paging DCI.

Optionally, the paging DCI may be scrambled using a paging radio network temporary identity (paging radio network temporary identifier, P-RNTI).

Alternatively, the second information may be represented by a field in a short message (short message) in the paging DCI. For example, the second information may be represented by an existing field in a short message (system information update field); alternatively, the second information may also be indicated by an unused reserved field in a short message in the paging DCI.

In some embodiments, the network device may send the second information to the terminal device through a specific radio network temporary identity (radio network temporary identifier, RNTI) scrambled paging (paging) message. For example, the network device may send a paging message scrambled by a dedicated or predefined RNTI, the second information being carried in the paging DCI; accordingly, the terminal device may monitor the paging message scrambled by the dedicated or predefined RNTI, or the terminal device may monitor the paging message scrambled by the dedicated or predefined RNTI to obtain the second information.

Alternatively, the dedicated or predefined RNTI may be protocol specified.

Optionally, the terminal device may monitor the paging message in a public search space; or the terminal equipment can monitor the paging message in a special search space configured by the network equipment; alternatively, the terminal device may monitor the paging message in a search space configured by the network device and dedicated to receiving the second information.

Alternatively, the second information may be represented by a field in a short message (short message). For example, the second information may be represented by an existing field in a short message (system information update field); alternatively, the second information may be indicated by an unused reserved field in the short message.

After S220, the method 200 may further include step S230, specifically as follows:

and S230, the terminal equipment performs service transmission aiming at the target slice according to the first information.

For example, the terminal device may acquire information of the target slice according to the first information, and perform service transmission for the target slice.

For example, the terminal device may obtain the information of the target slice according to the first information, determine a service area of the target slice and/or an available time of the target slice according to the information of the target slice, and perform service transmission for the target slice in the service area and/or the available time.

In some embodiments, the terminal device performs service transmission for the target slice according to the first information, and may include at least one of the following:

The terminal device does not use or delete the information of the target slice in the case that the terminal device is not in the available time of the target slice and/or is not in the service area of the target slice;

the terminal equipment uses the target slice in the condition that the available time of the target slice is within, and/or performs service transmission aiming at the target slice according to the first information;

the terminal equipment uses the target slice in the condition of the service area of the target slice, and/or performs service transmission aiming at the target slice according to the first information;

the terminal device uses the target slice within the available time of the target slice and within the service area of the target slice, and/or performs service transmission for the target slice according to the first information.

It should be noted that, the available time of the target slice may be understood as: the effective time of the target slice, or the service time of the target slice. The time of availability of the target slice may be a certain time or a certain period of time, and the terminal device may use the target slice and/or perform traffic transmission to the target slice during the time of availability of the target slice. Alternatively, the time of availability of the target slice may be represented by a timer. For example, the value of the timer duration may be used to indicate the time available for the target slice.

For example, the value of the timer duration may be used to indicate the time available for the target slice, and then the terminal device may use the target slice and/or perform traffic transmission to the target slice before the timer expires.

As another example, in the event that the timer expires (i.e., not within the time of availability of the target slice), the terminal device may not use or delete information for the target slice.

The service area of the target slice can be understood as: the area or location where the target slice can provide service, or the area or location where the target slice can support, may be used by a terminal device and/or traffic transmission to the target slice within the service area of the target slice. Optionally, the service area of the target slice may be represented by at least one of a cell identifier (e.g., a home zone or a neighboring zone) corresponding to the target slice, a frequency point (or a frequency point priority) corresponding to the target slice, a Tracking Area (TA) corresponding to the target slice, and a Routing Area (RA) corresponding to the target slice.

For example, the service area of the target slice may be cell #01, and then, if in the cell #01, the terminal device may use the target slice and/or perform traffic transmission to the target slice.

For another example, if in the cell #01, the terminal device may not use or delete the information of the target slice.

Of course, as in the previous embodiments, it is also possible to determine whether to use the target slice and/or to perform traffic transmission for the target slice in combination with the service area of the target slice and/or the available time of the target slice.

For example, in case the timer expires and is not within the cell #01, the terminal device may not use or delete the information of the target slice.

For another example, in case the timer has not expired and is within the cell #01, the terminal device uses the target slice and/or performs traffic transmission for the target slice according to the first information.

The paging DCI may carry indication information (i.e., the second information), where the indication information is used to indicate at least one of information of a target slice, a system information change for the target slice, and a target slice supported or to be supported by the network device. Alternatively, the paging DCI may be scrambled using a P-RNTI.

Alternatively, the indication information may instruct the terminal device to acquire the target slice (or information of the target slice) at a predetermined or indicated time period (or time).

For example, the indication information may be used to indicate at least one of: the terminal equipment acquires the target slice in the current system information change period; the terminal equipment acquires the target slice in the next system information change period; the terminal equipment acquires changed system information corresponding to the target slice in a current system information change period; and/or the terminal equipment acquires the changed system information corresponding to the target slice in the next system information change period.

Alternatively, the indication information may be represented by an existing field (system information update field) in a short message (short message) in the paging DCI. For example, the indication information may multiplex the 1 st to 3 rd fields in the short message, and the short message and its fields in the prior art are shown in table 1 below.

TABLE 1 short message and fields thereof

As shown in table 1, the 1 st field (systeminfoomodification) is used to indicate the update of SIB messages other than SIB6, SIB7 and SIB8, the 2 nd field (etwsandcmasendirection) is used to indicate that the terminal device receives a system message (e.g., SIB6, SIB7 or SIB 8) including public safety related information in the current system information update period, the 3 rd field (steppaging monitoring) is used to indicate a physical downlink control channel (physical downlink control channel, PDCCH) occasion for paging messages in the terminal device stopping the current paging occasion, and the 4 th to 8 th fields are reserved fields currently.

Alternatively, the indication information may also be indicated by an unused reserved field in the short message in the paging DCI, and the corresponding short message and its fields are shown in table 2 below.

S330, the network equipment sends SIB information to the terminal equipment.

The SIB message may carry information of the target slice.

Optionally, the network device may broadcast an SIB message, and accordingly, the terminal device may monitor the SIB message to obtain information of the target slice carried by the SIB message.

S340, the terminal equipment acquires the information of the target slice according to the SIB message and performs service transmission aiming at the target slice.

The information of the target slice may include at least one of: the method comprises the steps of identifying a target slice, identifying a slice group where the target slice is located, identifying a frequency point corresponding to the target slice, prioritizing the frequency point corresponding to the target slice, serving area of the target slice and available time of the target slice.

Alternatively, the time of availability of the target slice may be represented by a timer. For example, the timer duration is used to indicate the effective time (or time available) of the target slice. The service area of the target slice may be represented by at least one of a cell identifier (e.g., a home zone or a neighboring zone) corresponding to the target slice, a frequency point (or a frequency point priority) corresponding to the target slice, a Tracking Area (TA) corresponding to the target slice, and a Routing Area (RA) corresponding to the target slice.

Optionally, when the target slice is available, the first information may include information of the target slice; and/or, when the target slice is not available, the first information may not include information of the target slice.

In the embodiment of the present application, the paging DCI carries the indication information, so that the support of the network device to the target slice can be broadcasted by using the existing system information change mechanism as much as possible.
