Description

Device to device service resource configuration method and device

Technical field

The present invention relates to the field of device-to-device service resource configuration, and in particular, to a device-to-device (D2D) service resource configuration method and device.

Background technique

With the development of wireless multimedia services, the demand for high data rates and user experiences is increasing, which places high demands on the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of social networking, near-field data sharing, local advertising, and other applications has led to an increasing demand for people who are interested in and interested in nearby neighborhoods (eg, proximity services, Proximity Services). Traditional base station-centric cellular networks have significant limitations in supporting high data rates and proximity services. In this context, D2D technology, which represents a new direction for future communication technologies, has emerged. The application of D2D technology can reduce the burden on the cellular network, reduce the battery power consumption of the user equipment, increase the data rate, and improve the robustness of the network infrastructure, which satisfies the requirements of the above high data rate service and proximity service.

D2D technology can work in licensed or unlicensed bands, allowing multiple D2D-enabled user equipment (ie, D2D User Equipment, D2D UE) to be directly or without network infrastructure. Discovery / direct communication. D2D technology usually includes D2D discovery technology and D2D communication technology: D2D discovery technology refers to determining/determining the proximity between two or more D2D user devices (for example, within the scope of direct D2D communication) or for A technique of determining/determining that the first user equipment is adjacent to the second user equipment. Generally, D2D user equipment can discover each other by sending or receiving discovery signals/information. Under the coverage of cellular network, the network can assist D2D user equipment to perform D2D discovery; D2D communication technology refers to partial or complete communication between D2D user equipments. A technology in which data can communicate directly without going through a network infrastructure.

Terminals in the vicinity use D2D direct communication to bring many benefits to the terminal, such as higher speed, lower latency and lower power consumption, and also greatly improve the wireless resource efficiency of operators. The Relay mode facilitates operators to improve wireless coverage; for applications, the use of proximity information in the D2D communication process can lead to more attractive new services. Public The Public Safety system can also use D2D technology to enable communication between terminals without wireless coverage.

The D2D technology generally includes a D2D discovery technology and a D2D communication technology, where the D2D discovery technology is used to determine/determine the proximity between two or more D2D user devices (for example, within a range in which D2D direct communication is possible) Or a technique for determining/determining that the first user equipment is adjacent to the second user equipment. Generally, D2D user equipment can discover each other by sending or receiving discovery signals/information. In the case of cellular network coverage, the network can assist D2D user equipment for D2D discovery; D2D communication technology refers to parts between D2D user equipment or A technique in which all communication data can communicate directly without going through a network infrastructure.

D2D discovery technology may be divided into two different ways, one way is direct D2D discovery

(Direct discovery), the other way is EPC mode, that is, the geographical location information of each terminal is saved through the core network, and the D2D discovery function is provided according to the information.

The D2D-related topic in the 3rd Generation Partnership Project (3GPP) is called Proximity-based Services (ProSe), which focuses on Long Term Evolution (LTE) and evolution. Under the Evolved Packet Core (EPC) architecture, how to implement D2D services. A typical 3GPP architecture is shown in Figure 1. The functions of the key network elements are described below.

Terminal: Also called User Equipment (UE), Base Station: Also called eNodeB (Evolved NodeB, evolved NodeB) in the evolved system, mainly provides radio resources for terminal access, and mobile management unit of the core network. Interworking through the S1 interface. The core network provides non-access layer management, and the Prose server provides registration authentication for D2D services.

In the related art, the terminal may be in different states for the purpose of power saving of the terminal. In the related art, the terminal may be in an idle mode (RRC_IDLE) or a connected mode (RRC-CONNECTED). In the related LTE technology, the UE in the idle mode does not send and receive data, and only wakes up periodically to monitor the network to determine whether there is a service belonging to itself, and the network side does not save the context of the UE. The UE does not occupy system resources when roaming. The UE in the connected mode can accept and transmit data, and the network side reserves the context of the UE to support the UE to switch to other base stations. In both modes, the UE should be able to perform D2D discovery and D2D communication. However, since the D2D service may share original system resources such as LTE system resources, The network side should have a method to configure whether the terminal is allowed to perform D2D services in different states and whether it is allowed to perform which types of services.

On the other hand, the transmission of D2D services requires a certain amount of radio resources. The acquisition of D2D radio resources can be divided into two different types, namely, resource allocation type 1 (Type 1) and resource allocation type 2 (Type 2). Resource allocation type one is characterized by allocating resources for one or all of the D2D terminals. Resource allocation type 2 is characterized by allocating resources for a single D2D terminal. Resource type 2 can be divided into two subclasses, namely resource type 2A subclass and resource type 2B subclass. The resource type 2A subclass is characterized by assigning resources for each transmission. The resource type 2B subclass is characterized by half. Static allocation of resources. The typical mechanism of the resource allocation type 1 mode is the carrier sense multiple access mechanism (CSMA). The typical mechanism of the resource allocation type 2A is the dynamic scheduling mode used in the LTE or UMTS system. The typical mechanism of the resource allocation type 2B is in the LTE system. Semi-static scheduling. The network side should have a method to configure the terminal to use different resource allocation methods.

The current protocol and the literature do not address how the network configures how the terminal performs D2D services and how to use resource allocation in different states.

Preferred embodiment of the invention

The current protocol and literature do not address how the network configures D2D services and resource allocation in different states.

In order to solve the above problem, an embodiment of the present invention provides a device-to-device service resource allocation. Method and device. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Embodiment 1

The embodiment of the invention provides a device-to-device service resource configuration method. As shown in FIG. 1 , in an application scenario of the embodiment of the present invention, the terminal is in a network coverage scenario, and the terminals are all under the same base station coverage. In the embodiment of the present invention, the network management system is configured on the network side, and the network side configures the terminal through system messages. In the scenario shown in FIG. 1, the process of configuring a terminal to complete a D2D service by using the device-to-device service resource configuration method provided by the embodiment of the present invention is as shown in FIG. 2, and includes:

Step 201: The base station acquires configuration information by using the network management.

The content of the configuration information indicates how the terminal performs D2D services in different states and how to use the resource allocation method. The configuration information may be configuration information for a resource pool of the D2D service in the local cell, and may be configuration information for a single resource pool or configuration information for all resource pools in the cell, including a single resource pool in the cell or The following for all resource pools:

D2D discovers the functional resource allocation type (ie, resource allocation method), D2D communication function resource allocation type (transmission permission), D2D discovery function and status (function license), and unicast, multicast, or broadcast function and status (state license).

When the terminal is at the cell edge, it may need to receive D2D services from other cells. Therefore, it is necessary to learn other cell D2D resource information, resource configuration mode, and service permission information. Therefore, the configuration information may further include resource pool information and corresponding configuration information of the D2D service of the neighboring cell of the neighboring base station.

The content of the configuration information is the configuration of the network for D2D services in different states and the configuration of resource allocation. The content of the configuration information can be as shown in Table 1.

The configuration information can be for a specific resource pool or for all resource pools in the cell:

The base station may allocate one or more resource pools (Pools) for the D2D service, and the resource pools physically correspond to time and frequency resources within the rated range. The resource pool may be unified by the entire network, for example, a dedicated resource pool, that is, whether the network is not covered or the network The same time and frequency resources are used between cells controlled by multiple base stations within the coverage area. The resource pool may also be a cell-specific pool. The resource pool allocated to the D2D service is not completely consistent. The network side may configure a different configuration information for each resource pool. As shown in Table 1, each resource pool in the resource pool list of the cell has its corresponding configuration information.

The network side can also allocate a unified set of configuration information for all resource pools of the entire cell, and does not distinguish between separate resource pools, and allocates unified D2D service licenses and different resource allocation modes in the cell. If the cell has multiple resource pools, These resource pools all use a unified configuration; Table 1 shows the D2D service license information for each resource pool. Table 1

table) Explanation of the specific configuration:

The configuration information can be further divided into four categories. The first type is a function license. As shown in the third column of Table 1, the resource pool or the cell supports D2D discovery and/or D2D communication. The second type is status permission. As shown in the fourth column of Table 1, whether the terminal is allowed to perform the D2D function in the idle mode and/or the connected mode; the third type is the transmission permission, as shown in the fifth column of Table 1, The fourth type is the resource allocation mode. As shown in the sixth column of Table 1, the resource allocation mode of the terminal type 1 or type 2A and/or type 2B is configured.

For the first type of configuration, as shown in the third column of Table 1, line 1, for example, configured as "D2D discovery only", the terminal should not initiate D2D communication or accept D2D communication in this resource pool;

For the second type of configuration, as shown in the fourth column of Table 1, line 1, if the configuration is "allow only connection mode", the terminal cannot initiate D2D service (discovery and / or communication) in idle mode;

For the third type of configuration, as shown in the fifth column of Table 1, line 1, for example, configured as "allow acceptance mode", the terminal does not wait for the D2D service to be initiated;

For the fourth type of configuration, as shown in the sixth column of Table 1, line 1, for example, if it is configured as Type 1 (Type 1), the terminal obtains the resource before sending the service, and uses the type 1 resource allocation method in the form of competition.

The configuration information may also include information about the cell. If the terminal is in the edge region of the two cells, the terminal needs to use the resource pool of the neighboring cell if the terminal needs to initiate D2D discovery or D2D communication. Use D2D resources of other cells. For example, as shown in row 1 of Table 1, the neighboring cell function license, status license, transport license, and resource allocation mode can all be configured:

For example, for the first type of configuration, as shown in the third column of row 2 of Table 1, for example, "D2D discovery only", if the terminal is camping on the cell, it can monitor whether there is D2D in the resource pool in the neighboring cell. The function is found, but the D2D communication function cannot be performed.

For example, for the second type of configuration, as shown in the fourth column of row 1 of Table 1, for example, the configuration is "allow only idle mode", when the terminal is in the connected state, the D2D function cannot be performed on the resource pool in the neighboring cell; for example, For the third type of configuration, as shown in the fifth column of row 1 of Table 1, for example, the configuration is "Allow Accept and Send", if the terminal allows D2D discovery, it can use the resource pool of the neighboring area to initiate D2D discovery request message;

For example, for the fourth type of configuration, as shown in the sixth column of row 1 of Table 1, for example, configured to "allow Type 1", and the first three configurations allow D2D function, the terminal can initiate D2D function, and the required transmission The resource is obtained through the Type 1 method and the terminal of the community and the neighboring area through competition. For example, if the configuration is set to "Do not allow Type 1", and the first three configurations allow the D2D function, the terminal can only accept the D2D message sent by the neighboring terminal at this time, and cannot reply.

The configuration information may also be based on a cell rather than a specific resource pool, and may be classified as being based on the local cell and the neighboring cell; and the method for a specific resource pool, the function permission, the state permission, the transmission permission, and the resource allocation manner It can be configured, but the configuration is for the cell level. In this way, the terminal uses the same configuration in any D2D resource pool in the cell range.

The configuration information may also be a unified configuration of the entire network, and not only for a certain base station or a certain cell. This is because the D2D resources can be dedicated resources, and the time-frequency resources used by the entire network are consistent. Therefore, the configuration information of each cell can be configured exactly the same, so that the terminal can use these in the same form after obtaining the configuration. A public D2D resource pool.

The NMS configures configuration information to the base station through an interface located on the south side thereof.

Step 202: The base station configures the terminal by using a system broadcast message.

In this step, the terminals are all within the network coverage, so the system broadcast message can be accepted. For example, a new configuration item may be added to the related system broadcast message to carry the configuration information, and when the terminal reads the system broadcast message, the configuration is read and saved.

You can also use the new system broadcast message to send configuration information. When the terminal reads the system broadcast message, it reads and saves the configuration information.

The configuration information can be configured separately. For example, the configuration information content of the resource allocation class is in a system broadcast message, and the configuration information content of the status permission class is in another system broadcast message.

The configuration information can be carried in the system broadcast message in the form of a Bitmap. If the configuration is "Yes", the corresponding value is 1 . If the configuration is "No", it corresponds to 0.

The configuration information can also be carried in the system broadcast message in an explicit configuration, that is, the configuration item is explicitly configured to the terminal. For example, the configuration item is configured as optional. If the configuration is "Yes", the configuration item name is Appears in the configuration list, if the configuration item is configured to "No", then the configuration Setting the project name does not appear in the configuration list. This method is more efficient when only a few configuration items are "yes".

The configuration information can also be carried in the system broadcast message in the form of an implicit configuration, that is, there is a dependency relationship between the configuration items. By this dependency, only the data of some configuration items is sent, and the terminal can calculate the remaining part. The data of the configuration project. For example, it can be assumed that in the case of resource allocation type 2A/B, the terminal should be configured to allow D2D discovery information to be transmitted in the connection mode, and to allow D2D communication information to be transmitted in the connection mode. In this way, the network side can send all the configuration items to the terminal only by sending the resource allocation type.

Step 203: The terminal receives the configuration information, and configures and performs the D2D service according to the configuration information.

In this step, the terminal reads the system broadcast message, extracts the configuration information from the terminal, and performs the D2D service according to the configuration information, whether the terminal is in the connected state or the idle state.

The detailed description of the configuration information in the reference step 201 is specifically performed.

Embodiment 2

The embodiment of the invention provides a device-to-device service resource configuration method. As shown in FIG. 1 , in an application scenario of the embodiment of the present invention, the terminal is in a network coverage scenario, and the terminals are all under the same base station coverage. In the embodiment of the present invention, the core network element configures the network side by using an interface message, and the network side configures the terminal by using a radio resource connection management (RRC) message.

In the scenario shown in FIG. 1 , the process of configuring the terminal to complete the D2D service by using the device-to-device service resource configuration method provided by the embodiment of the present invention is as shown in FIG. 3 , and includes:

Step 301: The base station acquires the configuration information from the core network element by using the S1 interface.

In this step, the core network element (for example, the MME) obtains configuration information through a network management system or an interface. For configuration information, refer to Table 1 in Embodiment 1 of the present invention. The core network element sends the configuration to the base station through the S1 interface. In the S1 interface message between the radio access network and the core network, a management procedure may be used, for example, using a related message, such as a configuration update message carrying a new configuration field, This configuration field fills in the configuration information. In this way, if a new configuration occurs, the core network element can be updated. The core network element can also use the SI application message flow (S1AP procedure) message to carry the new configuration field, and fill in the configuration information in the configuration field. For example, the INITIAL CONTEXT SETUP REQUEST can be used to carry a new configuration field, which needs to wait for each terminal to initiate a service, but this method can provide a customized configuration based on each terminal. .

Step 302: The base station sends the configuration information to the corresponding terminal by using a radio resource connection management (RRC) message.

When the configuration is delivered to the terminal through the RRC message, the network needs to consider whether the terminal supports the D2D capability. Otherwise, the configuration does not need to be sent to the terminal that does not support the D2D function. For example, the D2D capability information of the terminal may be carried in the INITIAL CONTEXT SETUP REQUEST to obtain which terminals support the D2D function.

In this step, if the terminal is in the idle state, the terminal should enter the connected state. When accessing the base station, the base station sends configuration information through an RRC message, for example, by using an RRC connection setu (RRC connection setu);

If the terminal is in the connected state and a new configuration occurs, the RRC reconfiguration message can be used.

A message such as (RRC reconfiguration) sends configuration information to the terminal.

Step 303: The terminal receives the configuration information, and configures and performs the D2D service according to the configuration information.

In this step, the terminal retains the received configuration information. When the terminal enters the idle state, the configuration information remains valid for a certain period of time. For example, the terminal can trigger a timer when the configuration is obtained, for example, 2 hours. If the terminal is not powered off, and the timer is not timed out before the new configuration is received, the terminal considers that the previously received configuration information is valid. If the terminal moves out of the network, if the new configuration is not accepted and the timer does not time out, the terminal considers that the previously received configuration information is valid.

Embodiment 3

The embodiment of the invention provides a device-to-device service resource configuration method. As shown in FIG. 4, in an application scenario of the embodiment of the present invention, the terminal is in a network coverage scenario, and the terminals are all under different base station coverage. In the scenario shown in FIG. 4, the process of configuring the terminal to complete the D2D service by using the device-to-device service resource configuration method provided by the embodiment of the present invention is as shown in FIG. 5, and includes:

Step 501: The base station acquires configuration information.

Different base stations can obtain the configuration information through the network management system, and can also obtain the configuration information through the core network element. For the specific acquisition mode, refer to the first embodiment and the second embodiment of the present invention, and configure the local network through the network management system and the core network element. The configuration of the neighboring cell is obtained through an inter-base station interface.

The inter-base station interface may use an X2 interface. In the X2 interface message, a non-UE-associated signalling may be used, for example, using a related message, such as a base station configuration update.

The (ENB CONFIGURATION UPDATE) message carries the new configuration field, and the configuration information is filled in the configuration field. In this way, if a new configuration occurs, the base stations can be updated.

The user equipment UE related process (UE-associated signalling) message may also carry a new configuration field, and the configuration information is filled in the configuration field. For example, a new configuration field can be carried in the HANDOVER REQUEST, which needs to wait for each terminal to initiate a service, but this method can provide a customized configuration based on each terminal.

Optionally, to provide consistent configuration information, the NMS should ensure that the configuration information is the same.

Step 502: The base station sends the configuration information to the corresponding terminal.

In this step, different base stations can configure the terminal in different manners. For example, one base station can configure the terminal by using the system broadcast message, and another base station can manage the message configuration terminal by using the wireless resource connection.

Step 503: The terminal receives the configuration information, performs configuration according to the configuration information, and performs a D2D service.

In this step, the terminal retains the obtained configuration information. When the terminal obtains the idle state, the configuration information remains valid for a certain period of time when the terminal enters the idle state.

Embodiment 4

The embodiment of the invention provides a device-to-device service resource configuration method. As shown in Figure 6, Some terminals are under network coverage, and some terminals are outside network coverage. In the embodiment of the present invention, the terminal performs the service by using the configuration information obtained in the network coverage.

In the scenario shown in FIG. 6, the process of configuring the terminal to complete the D2D service by using the device-to-device service resource configuration method provided by the embodiment of the present invention is as shown in FIG. 7, which includes:

Step 701: The base station acquires configuration information.

In this step, the base station can obtain the configuration through the network management system to which it belongs, or obtain the configuration through the core network element. For specific acquisition methods, refer to Embodiment 1 and Embodiment 2 of the present invention.

Optionally, the configuration information should be a unified configuration of the entire network. When the terminal moves out of the coverage range of the current base station and returns to the vicinity of the coverage of other base stations, the same configuration information is used to reduce the possibility of collision.

Step 702: The base station sends the configuration information to the terminal.

In this step, the base station may send the configuration information to the terminal in different manners. For example, the base station may send the configuration information by using the system broadcast message, or may send the configuration information to the terminal by using the radio resource connection management message.

Step 703: The terminal receives the configuration information, performs configuration according to the configuration information, and performs a D2D service.

In this step, the terminal saves the received configuration information. If the terminal moves out of the network coverage within the validity period of the configuration information, the terminal uses the configuration information and the D2D service such as D2D discovery and D2D communication in the network coverage.

If the configuration information is invalid (for example, the time for saving the configuration information exceeds the validity period), the terminal should use the pre-configured D2D service mode. The pre-configured D2D service mode should ensure that no conflict occurs with other terminals. For example, the resource allocation type uses a special frequency band at one time.
