Abstract

Disclosed are a method and a device for controlling radio resources. According to the method: when an RRC connection is established between a UE and a network, the network receives an RRC connection-established message from the UE, said message carrying access information; and the network determines whether to maintain the RRC connection according to network load status and to the access information. The present invention solves the problem of admission control being unable to meet the high density of multi-service UEs due to insufficient flexibility of existing control mechanisms.

Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a radio resource control method and apparatus. A third-generation mobile communication Long Term Evolution (LTE) system consists of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and a User Equipment (UE). The Evolved Packet Core (EPC) is an evolved packet core network. The E-UTRAN is composed of an enhanced base station (e B) of the access network element. The e B is connected to the terminal UE through the Uu interface, and is connected to the core network element, such as a Mobility Management Entity (MME), through the S1 interface. At present, the network side has a multi-level access control processing mechanism for the access of the user equipment, so as to ensure that the network side does not overload due to excessive user equipment access. The user equipment accesses the network side and needs to complete several processes as shown in FIG. 1. In this example, the network side access device is set as the mobility management entity MME: Step 102: Random access procedure: The user equipment completes through the process. Synchronization with the network side; Step 104: Radio Resource Control (RRC) connection establishment process: establishing a signaling bearer of the user equipment and the access network network element; Step 106, attaching (Attach) process: completing the user equipment Identification information acquisition, authentication process, and security setup (Security Setup). In the existing protocol, the network side sets 15 access levels (ACs) for different call types. The normal calls belong to AC0~9, and the emergency calls belong to AC10. Other high-priority calls belong to AC11~15. The network side sets a control factor for AC0 9 and sets the "No Forbidden" flag for AC10 and AC11 15 and broadcasts it to the user equipment to control the random access behavior of these call types. In the RRC connection establishment process, the signaling interaction between the user equipment and the access network element is as shown in FIG. 2, FIG. 3 and FIG. 4, and there are three processes of connection establishment, connection rejection and connection release, in FIG. 2 and FIG. 3 And in the schematic diagram of FIG. 4, the network side access device is a base station. As shown in FIG. 2, the connection setup includes the following steps: Step 202: The user equipment initiates an RRC connection setup request. Step 204: The base station feeds back an RRC connection setup message to the user equipment. Step 206: The user equipment sends an RRC connection setup complete message to the base station. As shown in FIG. 3, the connection rejection includes the following process: Step 302: The user equipment initiates an RRC connection establishment request. Step 304: The base station feeds back an RRC connection rejection message to the user equipment. As shown in FIG. 4, the connection release includes the following process: Step 402: The base station sends an RRC connection release message to the user equipment. Through the three processes, the network side can "accept", "reject" and "release" the RRC connection establishment request of the user equipment according to its own data load capacity and signaling load capacity, and air interface load capability. "The judgment." Considering that the connection request initiated by the user equipment may be based on different types of services, and the priorities of the services may be different, in order to implement more flexible and efficient admission control, in the current RRC layer protocol, the user equipment is required to be in the RRC. The connection establishment request (RRC Connection Request) carries the reason information of the connection establishment. The existing connection establishment information includes the following: Emergency (emergency, indicating that the user equipment initiates an emergency call);

High Priority Access (high priority access, indicating that the user equipment initiates a high priority service class call); mt-Access (indicating that the user equipment is applying for a connection due to the called party); mo-Signalling (indicating that the user equipment is the initiator) Called signaling class); mo-Data (indicating that the user equipment is the originating caller data type call). It should be noted that the above connection establishment reason information is only applicable to user equipments of 3GPP release 9 and previous versions. Since the current RRC connection setup request message is carried in the message of the random access procedure, and the size of the message 3 message is limited, it is no longer possible to add more new information in the RRC connection setup request message. With the development of the concept of Internet of Things, M2M (Machine to Machine) communication (called machine type communication in 3GPP, or MTC) will gradually be introduced to the whole society. The definition of M2M in a narrow sense is machine-to-machine communication. Broadly defined is a networked application and service centered on intelligent interaction of machine terminals. It is based on intelligent machine terminals and uses multiple communication methods as access means to provide customers with information solutions to meet customers' information needs in monitoring, command and dispatch, data acquisition and measurement.

In the application of M2M, the business types are very wide, such as household meter reading, industrial production instrumentation automation, water quality monitoring, intelligent transportation and asset tracking, etc. M2M applications will enter all walks of life, thousands of households, and M2M business types also There will be tens of thousands, and the QoS (Quality of Service) requirements for the network side and for operators will also be varied. The number of M2M user devices will also far exceed the current mobile phone terminals, which poses a huge pressure on the current and future wireless networks. Due to the huge number of M2M user equipments, 3Gpp currently proposes the concept of managing user equipments in a group manner. In the context of M2M applications, how to protect the network and how to prevent network overload has become a primary problem. In the current protocol, the user equipment may perform access control on the random access procedure or the user equipment in the RRC layer during the process of establishing a connection with the network and completing the attachment. The RRC connection establishment request is controlled, but the flexibility of the current control mechanism cannot meet the admission control of the high-density, multi-service user equipment. For example, the current statistics of operators show that the load of data services (such as Internet access, video call port, FTP (File Transfer Protocol) download) in wireless communication has exceeded the load of voice services. When the network is under overload pressure, it is more appropriate to impose certain acceptance restrictions on the data service to ensure the normal service of the voice service, because usually from the perspective of the operator, the voice service is the basis of the network operation, but according to the current Protocol standard, when the user equipment initiates a voice call and a data service call, the connection establishment cause information in the RRC connection establishment request is the same data model mo-Data, and the network side cannot distinguish between voice or data service, and thus cannot be flexible. Admission control. In addition, different M2M applications have different business models. The business model refers to the data transmission model when the user equipment and the network side exchange data. The elements of the business model include: data interaction periodicity, data interaction frequency, data size, Data interaction direction (refer to the above line data, or the following line data, or up and down The traffic is similar). Take smart meters as an example. Some power companies require each smart meter to report meter reading data every 5 minutes. Some power companies require each smart meter to report meter reading data every hour. Some power companies even only require intelligence. The meter reports the meter reading data once a day, and the traffic of each meter reading data is small. This constitutes three different business models, which can be called high frequency periodic small data reporting, low frequency periodic small data reporting, Very low frequency periodic small data is reported. Another example is a normal voice service, which can be called an extremely high frequency periodic small data interaction model. For example, the Internet service (usually clicking on a web page for several tens of seconds, the following line data is dominant, and the data traffic is large) may be referred to as an intermediate frequency non-periodic big data downlink model. These different business models clearly have different pressures on the network, and the current mechanism is unable to distinguish the models of these services. Different services also have different QoS requirements. The QoS requirements related to admission control include: access delay tolerance. For example, some services are very sensitive to access delay (such as fire alarm, security, medical monitoring, etc.). The business is less sensitive to access delays (such as meter reading), and the current mechanism is unable to distinguish between these differences. Different services or user equipments also have different priorities. For example, financial, security, and medical-related services should have higher priority than ordinary services, and the current mechanism cannot be distinguished. The above defects will become more serious after the widespread use of M2M. The flexibility of the current control mechanism in the related art has been unable to meet the problem of admission control for high-density, multi-service user equipment, and no effective solution has been proposed yet.

The various access information will be specifically described below. In the following discussion, specific examples of various access information are listed. The call service type information refers to information classified by call service, including one or more of the following: a voice call of the calling party or the called party, a video stream call of the calling party or the called party, an interactive voice call of the calling party or the called party. , the calling or called data call, the calling or called signaling service, etc. Among them, the data call can be only a simple one, or can be further divided into more detailed categories, such as: HyperText Transfer Protocol (Http) Internet service, FTP download service, meter reading service, monitoring service, intelligent traffic service , asset tracking business, etc. The type information of the user equipment refers to information classified by the user equipment, including one or more of the following: H2H user equipment, M2M user equipment, and other types of user equipment. The group information of the user equipment refers to the identifier of the user equipment group, including: the serial number or identifier of the user equipment group (Group). According to the mechanism of the current group, the Group-RNTI (Radio Network Temporary Indicator) has been proposed at the 3gpp conference. Therefore, the group information of the user equipment can be directly used by the Group-RNTI, and the network can also be used. A serial number pre-agreed by the side, and the network side establishes a one-to-one correspondence between the serial number and the group in advance. The priority information of the user equipment refers to the priority of the user equipment agreed by the network side and the user equipment in advance, including: the priority number or the priority identifier. The priority can be 1 or more, which can be higher than the existing H2H (Human To Human) device, or lower than the existing H2H device. For example: Based on the existing H2H device (the "H2H device" refers to the RRC connection establishment reason already included in the existing protocol), it can include the following types: Simple level 1: H2H device, low priority device (relative to H2H equipment); or

Level 2: High priority equipment, H2H equipment, low priority equipment; or multiple levels: H2H equipment, low priority level 1 equipment, low priority level 2 equipment, ..., low priority N level equipment (N is a positive integer); Another multi-level: high priority level 1 equipment, high priority level 2 equipment, ..., high priority M level equipment, H2H equipment, low priority level 1 equipment, low priority level 2 equipment, ..., low priority N Level device (M and N are positive integers); The correspondence between the specific device type and device priority is pre-agreed by the network side and the user equipment. For example, an H2H device belongs to a common priority, and an M2M device belongs to a low priority. The priority information of the service refers to the service priority agreed by the network side and the user equipment in advance, including: the priority sequence number or the priority identifier. Due to the introduction of smart phones and M2M devices, the types of wireless communication services are greatly increased. The reasons for the establishment of RRC connections in the existing protocols include: Emergency, indicating that the user equipment initiates an emergency call; highPriorityAccess indicates that the user equipment initiates a high priority. Service-type call; mt-Access, indicating that the user equipment is applying for establishing a connection due to the called party; mo-Signalling, indicating that the user equipment is a caller signaling type call; mo-Data, indicating that the user equipment is calling the calling data type call . In addition, new service priorities can be introduced, for example ("H2H service" refers to the RRC connection establishment reason already included in the existing protocol), and can include the following types: Simple level 1: H2H service, Low priority service (as opposed to H2H equipment); or

Level 2: High-priority service, H2H service, low-priority service; or multi-level: H2H service, low priority level 1 service, low priority level 2 service, ..., low priority N level service (N is a positive integer); Another multi-level: high priority level 1 service, high priority level 2 service, ..., high priority M level service, H2H service, low priority level 1 service, low priority level 2 service, ..., low priority N Class service (M and N are positive integers); The correspondence between the specific service type and the service priority is pre-agreed by the network side and the user equipment. For example, services with higher access time tolerance (such as smart meters) belong to lower service priorities, while services with lower access time tolerance (such as mobile POS machines, alarm M2M devices, etc.) are High business priority. There may also be correspondences between other service types and service priorities, which are not exemplified herein. The type information of the business model refers to the data communication model of the service, including one or more combinations of the following features: data interaction periodicity (whether it is periodic data interaction), data interaction frequency, data volume size, data interaction Direction (refer to the above data, or the following data, or the upstream and downstream traffic are similar). For example, a business model including only a simple feature information includes: a small data service model, or a high frequency business model, or a periodic business model, etc.; a business model including information of a plurality of characteristics includes: Data service model, low-frequency periodic small data reporting, very low-frequency periodic small data reporting, extremely high-frequency periodic small data interaction model, medium-frequency aperiodic big data downlink model, and so on. In implementation, the correspondence between the service type and the service model is usually pre-agreed by the network side and the user equipment. In the embodiment of the present invention, the PLMN type information is the PLMN type information agreed by the network side and the user equipment in advance, including one or more of the following: whether the user equipment is on the HPLMN, whether the user equipment is in its equivalent. Identification information on the HPLMN, whether the user equipment is in the identification information of a PLMN in the preferred PLMN list included in its SIM (Subscriber Identity Module) or USIM (Universal Subscriber Identity Module) Whether it is the identification information of the roaming user equipment, the identification information of the HPLMN of the user equipment, or the identification information of the equivalent HPLMN of the user equipment. The Access Class information of the user equipment on the network side refers to the access level agreed by the network side and the user equipment in advance, including: the access level sequence number or the access level identifier; for example: Access Class N (N is greater than A positive number equal to 0). The QoS requirement type information of the service includes a combination of one or more of various QoS requirements, such as: access delay tolerance, guaranteed traffic, allowable bit error rate, and the like. Taking the access delay as an example, it can be set to: Simple Level 2: Sensitive to access delay and insensitive to access delay; Multi-level: High access delay sensitivity, access delay sensitivity, and access delay sensitivity Low; can also be a combination of multiple QoS requirements, for example: High access delay sensitivity + low guaranteed traffic + low error rate requirements; or access delay sensitivity + high guaranteed traffic + low error rate requirements. In implementation, the QoS requirements can also be divided into smaller levels than the enumerated examples, depending on the circumstances. In one embodiment, the list may clearly indicate the access information of the RRC connection, and the list may be one or more of the various feature information described above, or a combination of one or more. For example, Table 1 is an embodiment of the RRC connection access nature information list (which is a combination of priority information, service type information, and user equipment type information): Table 1

Table 2 is another embodiment of the RRC Connection Access Property Information List (which is a combination of service model information and QoS requirement information): Table 2

In practical applications, there may be other combinations to form an access information list of the RRC connection, and the access information list may also contain more or less than seven access information, for example, one, two, three. Item, ten or any natural number. In the implementation, in step 502, the RRC connection is established between the user equipment and the network side. Before the implementation in step 502, the method may further include: determining, by the user equipment, the access information according to the type of the user and the service type of the service to be established, and connecting The incoming information is added to the RRC Connection Setup Complete message. When the network side determines whether to maintain the RRC connection according to the access information, different execution results may be selected. For example, when the determination result is yes, the network side may choose not to trigger the RRC connection release process, so that the user equipment and the network side maintain RRC connection; or, when the determination result is no, the network side may choose to trigger an RRC connection release procedure to release the RRC connection. In order to make the objects, the technical solutions and the advantages of the embodiments of the present invention more clearly, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The embodiment of the present invention is applicable to an LTE system or a UMTS (Universal Mobile Telecommunications System).

Step 606: The base station feeds back the RRC connection establishment to the user equipment. The message is: Step 608: The user equipment selects the corresponding access property information according to the current connection establishment property, and includes the information in the RRC connection setup complete message. Step 610: The user equipment sends an RRC connection setup complete message to the base station. Step 612 The base station determines whether the current RRC connection of the user equipment can be maintained according to the load status of the network side of the user equipment, if yes, go to step 614, if not, go to step 606; 614. If the base station agrees that the user equipment maintains the RRC connection, Send an RRC connection release procedure, the user equipment continues the subsequent connection process and a core network; Step 616: If the base station does not agree that the user equipment maintains the RRC connection, the RRC connection release procedure is triggered, and the RRC connection of the user equipment is released.
