technical field

The present application relates to the communication field, and in particular to a resource allocation method, a terminal, a network device, and a storage medium.

Background technique

The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) introduces this key technology of network slicing information in the 5th Generation mobile networks (5G) network. By dividing different slice information, different network resources, such as bandwidth, rate, and service quality, are allocated respectively, so that different service requirements can occupy network resources more reasonably.

In order to realize this function, the 3GPP protocol TS24.501 requires that when a terminal initiates a registration request, it shall carry the network slice information that the terminal wishes to request. The terminal fills in the network slice information that the terminal wishes to request according to the intersection of the pre-selected slice information selected by the application module in the slice information contracted under the home network and the terminal configuration slice information; or between the pre-selected slice information and the terminal configuration slice information When there is no intersection, fill in the network slice information that the terminal wishes to request according to the terminal's configured slice information.

However, when the terminal carries the configuration slice information in the registration request and sends it to the network device, the terminal needs to retry to combine the pre-selected slice information with the new slice configuration in the next registration process after the network device sends the new slice configuration in the registration response. The configured slice information is matched to request the pre-selected slice information from the network device, resulting in the slow speed of establishing a service channel for the terminal and the delay of the terminal service.

When the terminal enters the first network and performs In the registration scenario, at least part of the pre-selected slice information can be uploaded by requesting mapping slice information cells, and the pre-selected slice information can be sent to the network device in time, thereby improving the speed of establishing a service channel for the terminal and reducing the delay of terminal service.

It should be understood that the specific embodiments described here are only used to explain the present application. It is not intended to limit the application.

The embodiment of the present application provides a resource allocation method, as shown in Figure 1, the method applied to the terminal may include:

S101. Enter the first network and trigger the initiation process of the registration request message, and determine the pre-selected slice information; the pre-selected slice information is the slice information selected in advance from the subscribed slice information of the terminal.

A resource allocation method proposed in an embodiment of the present application is applicable to a scenario in which network slice information is allocated to a terminal during initial registration when the terminal enters the first network.

In this embodiment of the application, the first network may be a network that the terminal enters for the first time, or a network that the terminal does not enter for the first time, which may be selected according to actual conditions, and is not specifically limited in this embodiment of the application. Exemplarily, the scenario where the terminal enters the first network for the first time and performs initial registration may be as follows: in region 1, the terminal performs a power-off operation or an operation of turning on the flight mode, and after the terminal moves to region 2, the terminal performs a corresponding power-on operation or turns off the flight mode Mode of operation, at this time, the terminal enters the network of region 2 for the first time, and the terminal initiates initial registration under the network of region 2.

In some embodiments, the terminal may be called user equipment (User Equipment, UE). The terminal can be a personal communication service (Personal Communication Service, PCS) phone, a cordless phone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant) Assistant, PDA) and other equipment, the terminal can also be a smart phone, tablet computer, palmtop computer, mobile station (Mobile Station, MS), mobile terminal (Mobile Terminal), etc., the terminal can be connected via the wireless access network (Radio Access Network, RAN) communicates with one or more network devices. For example, the terminal can be a mobile phone (or called a "cellular" phone) or a computer with a terminal, etc. Inbound to exchange voice and/or data. Terminals can also be handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in future evolving networks, etc., which are not limited in the implementation of this application.

Network equipment is a kind of equipment that provides wireless communication functions for terminal equipment, including but not limited to: Long-Term Evolution (Long-Term Evolution, LTE) system, New Radio (New Radio, NR) system or Authorized Assisted Access Long-term Evolution (Licensed -Assisted Access using Long-Term Evolution (LAA-LTE) system in the evolved base station (evolutional Node B, may be referred to as eNB or e-NodeB), macro base station, micro base station (also called "small base station"), Pico base station, base transceiver station (Base Transceiver Station, BTS), base band unit (Base Band Unit, BBU), access point (Access Point, AP), transmission point (Transmission Point, TP) or new generation base station (new generation Node) B, gNodeB) and so on.

In the embodiment of this application, after the terminal enters the first network, the terminal needs to initiate a registration request message to the network device, and the registration request message needs to carry the network slice information that the terminal wishes to request, that is, Network Slice Selection Assistance Information (Network Slice Selection Assistance Information) , NSSAI), therefore, when the terminal initiates the registration request message, the terminal needs to determine the network slice information it wants to request. Specifically, the terminal first determines the preselected slice information selected by the application layer of the terminal from the slice information subscribed under the terminal's home network, and the preselected slice information is the Preferred NSSAI.

It should be noted that slicing information is a new function of 3GPP in 5G networks. The implementation process of slicing information is to divide network entities into multiple logically independent networks and allocate different network resources for each network, such as Bandwidth, rate, service quality, etc. In the process of network resource allocation, different slice information can be allocated according to different service requirements, which can more reasonably provide different network resources for different service scenarios.

S102. Add at least part of the preselected slice information to the request mapping slice information information element, and add the request mapping slice information information element to the registration request message.

In the embodiment of the present application, after the preselected slice information is determined, at least part of the preselected slice information is added to the requested mapping slice information information element. Specifically, the process of determining at least part of the preselected slice information includes: determining terminal configuration slice information; Match the configuration slice information with the pre-selected slice information, and add the pre-selected slice information to the requested mapping slice information information element if the configuration slice information and the pre-selected slice information are detected to be mismatched; when the configured slice information and the pre-selected slice information are detected In the case of at least a partial match between the information, the slice information matching the configuration slice information in the pre-selected slice information is added to the requested mapping slice information information element.

It should be noted that the configuration slice information may include the allocated slice information corresponding to the first network, that is, Allowed NSSAI, the configuration slice information corresponding to the first network, that is, Configured NSSAI, and the pre-configured slice information that is pre-configured by the user, that is, Requested NSSAI , at least one of , and the pre-selected slice information is the slice information selected by the application module of the terminal from the slice information subscribed under the home network of the terminal.

It should be noted that if the terminal enters the first network for the first time, there is no configuration slice information record under the first network inside the terminal, and at this time, a mismatch between the configuration slice information and the pre-selected slice information will be detected.

It should be noted that the above is only an application scenario where a mismatch between configured slice information and pre-selected slice information is detected, and other scenarios where a mismatch between configured slice information and pre-selected slice information can be realized are also within the scope of protection of this application. No longer.

It should be noted that since the configuration slice information includes at least one of the allocated slice information corresponding to the first network, the configuration slice information corresponding to the first network, and the pre-configured slice information configured in advance by the user, the configuration slice information will The process of matching with the pre-selected slice information may be: first determine whether there is an intersection between the pre-selected slice information and the allocated slice information corresponding to the first network, and if there is no intersection, further determine the pre-selected slice information and the first network Whether there is an intersection between the corresponding configuration slice information, if there is no intersection, then further determine whether there is an intersection between the pre-configured slice information and the pre-selected slice information time configured by the user, if there is no intersection, the configuration is detected Slice information and preselected slice information do not match.

It should be noted that the request mapping slice information information element is in TS24.501 of the 3GPP version above R16. In the current protocol version, the request mapping slice information cell is applied in the scenario of a mobility update registration request, and is used to report the home network, that is, the protocol data unit activated under the home public land mobile network (Home Public Land Mobile Network, HPLMN) (Protocol Data Unit, PDU) session-related subscription slice information. In this embodiment of the application, the application scenario of request mapping slice information cell is adjusted to the initial registration scenario in the process of network roaming, and the function of request mapping slice information cell is adjusted to report the slice contracted by the application layer from the terminal's home network The pre-selected slice information selected in the information, the terminal multiplexes the request mapping slice information information element during the process of entering the first network and performing initial registration, and adds the pre-selected slice information to the request mapping slice information information element.

Further, if there is an intersection between the preselected slice information and the allocated slice information corresponding to the first network, and/or there is an intersection between the preselected slice information and the configuration slice information corresponding to the first network, and/or the preselected slice information If there is an intersection between the pre-configured slice information and the pre-configured slice information configured by the user, at least a partial match between the configured slice information and the pre-selected slice information is detected, and the intersection between the configured slice information and the pre-selected slice information is the pre-selected slice information. The configuration slice information matches the slice information.

Further, the matched slice information may also be added to the requested slice information information element. At this time, the request slice information information element is added to the registration request message and sent to the network device.

11. Check whether there is pre-configured slice information pre-configured by the user;

12. If there is pre-configured slice information, determine whether there is an intersection between the pre-selected slice information and the pre-configured slice information;

3. If there is an intersection between the pre-selected slice information and the pre-configured slice information, fill in the matching slice information between the pre-selected slice information and the pre-configured slice information in the request mapping slice information information element.
