Description

Information processing method and mobile management entity

Technical Field

The present invention relates to the field of electronic technologies, and in particular, to an information processing method and a mobility management entity.

Background

In broadband Trunking Communication (B-TrunC) alliance specifications, a Trunking Core network architecture scheme based on an Evolved Packet Core (EPC) system is defined and has a plurality of decomposition modes. In the decomposition process, an interface between two logical entities, namely a Mobile Management Entity (MME) and a cluster control Function (TCF), is a T1 interface.

Please refer to fig. 1A, which shows a conventional B-TrunC system architecture. In the system, a terminal accesses a core network through a broadband cluster base station, establishes a data link channel through a protocol control process of an MME (mobility management entity), a High Speed Switch (eHSS) and a GateWay (GateWay, GW), and performs a cluster service through protocol control of a TCF (coordinated media function, TMF). On the other hand, the dispatcher station can perform dispatching control through interaction with the TCF/TMF.

In the existing alliance specification, the convention T1 interface is an internal interface of the EPS system. Currently, in a B-TrunC system, a Session Initiation Protocol (SIP) is usually used as a Protocol stack entity of a T1 interface, and a common T1 interface Protocol architecture is shown in fig. 1B, which needs to set Protocol entities corresponding to the SIP, such as SIP Protocol entities, in an MME and a TCF respectively, and analyze a relevant Protocol in a transmission process according to a Protocol transport layer in the figure, and perform service flow continuation.

Under the condition that the SIP protocol is used as a protocol stack entity of a T1 interface, for an MME, protocol conversion and process compatibility from an S1-T-C interface to a T1 interface are required, an SIP protocol module is required to be newly added on the MME, an original service process is modified into an SIP interface converted into a T1 interface, and the modification is large, so that the stability and the development efficiency of the service are influenced.

For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), smart watches, smart helmets, smart glasses, smart bracelets, and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Including, for example, bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and other information sensing devices.

In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and specific embodiments of the specification.

Example one

Referring to fig. 2, an embodiment of the present invention provides an information processing method, which can be applied to a mobility management entity MME, where the MME may be in the system architecture shown in fig. 1A. The steps of the method can be described as follows:

s11: the MME acquires an NAS message from the terminal, wherein the NAS message is used for indicating the service requested by the terminal.

In the embodiment of the invention, the MME can acquire the NAS message from the terminal through the base station, and the NAS message can indicate the terminal to request a registration service or indicate the terminal to request a call service and the like.

In practical application, the MME may receive a service request sent by the terminal through the base station, and after receiving the service request, the MME analyzes a service request message according to a protocol transport layer. In the embodiment of the present invention, the MME may parse and strip the service request in a transport layer before a non-access stratum (NAS) in a protocol transport layer, so as to obtain an NAS message in the service request.

For example, please still refer to the Protocol transport layer described in FIG. 1B, which runs the S1-AP layer on top of the Stream Control Transmission Protocol (SCTP) layer and the NAS layer on top of the S1-AP layer. Then, the MME may parse and strip the service request at the SCTP layer or the S1-AP layer, and obtain the NAS message in the service request.

S12: and the MME analyzes the NAS message and judges whether the message type of the NAS message is a preset message type or not.

In the embodiment of the invention, after the MME obtains the NAS message, the NAS message can be further analyzed, and the message type of the NAS message can be determined. Generally, message types of NAS messages include, but are not limited to, the following two types:

the first method comprises the following steps: a cluster message type. The message type may represent that the NAS message is a Trunking Service Message (TSM) for instructing the terminal to request handling of Trunking service.

And the second method comprises the following steps: the mobile message type. The message type may represent that the NAS message is a mobile communication related service for indicating that a service requested to be handled by the terminal is LTE, such as a service for session management.

In the embodiment of the present invention, the preset message type may be a trunking message type, and then, when the MME parses the NAS message, the MME may determine whether the NAS message is a trunking service message TSM used to instruct the terminal to request handling of trunking services, and if so, may determine that the NAS message is the preset message type.

S13: if the NAS message is of a preset message type, the MME transmits the NAS message to the TCF through a transmission link according to a preset transmission protocol; the preset transmission protocol is any one of a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), a Stream Control Transmission Protocol (SCTP) and a system queue protocol.

Generally, when the MME handles the trunking service, the MME needs to implement the trunking service in combination with the protocol control of the TCF. Therefore, in the embodiment of the present invention, when determining that the NAS message is of the preset message type, the MME may transparently transmit the NAS message to the TCF through the transmission link between the MME and the TCF, so as to process the NAS message through the TCF. During transparent Transmission, the preset Transmission Protocol used by the Transmission link may be any one of a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), an SCTP, and a system queue Protocol.

Certainly, in practical application, the transmission link between the eMME and the TCF may also support other transmission protocols, where the other transmission protocols do not include the SIP protocol, so as to avoid a situation that the transmission process is cumbersome due to the need of the MME and the TCF to implement relevant protocol analysis and service flow connection when the T1 interface based on the SIP protocol is used for data transmission in the prior art.

Therefore, in the embodiment of the present invention, the transmission link between the MME and the TCF is set to perform data transmission according to the preset transmission protocol, so that the T1 interface can be redefined, and the NAS message that is the preset message type is directly transparently transmitted, which is beneficial to reducing configuration operations and docking operations of the T1 interface by the two logical entities of the MME and the TCF.

In another embodiment of the present invention, if the MME determines that the NAS message is of the preset message type, before the MME transparently transmits the NAS message to the cluster control function TCF through a transmission link using a preset transmission protocol, a cluster process session index (TPTI) and a User Dialing Number (UDN) of the terminal may also be obtained according to the NAS message.

Further, the MME may generate header information (header) of the NAS message indicating information of a terminal transmitting the NAS message, from the message type, the TPTI information, and the UDN information.

In this embodiment of the present invention, the structure of the header information of the NAS message may be defined as follows:

typedef struct (definition structure) T1Header (T1 head)

{

MsgType (message type),

TPTI (cluster process session index),

UDN (user calling number)

}；

The MME may synchronously pass through the header information when passing through the NAS message. In the embodiment of the invention, the header information and the NAS message which is in the preset message type can be collectively referred to as a transparent transmission message.

Then, after the transparent transmission message is transmitted by the MME through the transmission link, the TCF monitors the message of the T1 interface to obtain the transparent transmission message, and can obtain the related terminal information by parsing the header, and further parse the NAS message to process the trunking service message, for example, modify the terminal information in the registration management module according to the registration request of the terminal, or perform operations such as bearer establishment, paging called party, and the like according to the call request of the terminal, and each service flow has a corresponding processing logic definition in the specification, which is not described herein again.

In the embodiment of the invention, the MME transmits the header information and the NAS information to the TCF simultaneously, so that the TCF distinguishes different terminals for sending requests through the terminal information in the header information, and processes the trunking service information by analyzing the NAS information, thereby being beneficial to promoting the service processing efficiency between the MME and the TCF. In another embodiment of the present invention, after S12, if the MME determines that the message type of the NAS message is not the preset message type, and the MME determines that the NAS message is the session management message ESM for indicating that the terminal requests to handle the session management service according to the message type of the NAS message, the MME may use an original software process to perform processing, for example, activate an Evolved Packet System (EPS) bearer context to receive or activate a dedicated EPS request context, so as to bear the session management service.

In the embodiment of the invention, the MME determines the message type of the NAS message, transmits the NAS message of different message types in different modes, and directly transmits the NAS message related to the cluster service to the TCF through the transmission link, so that the TCF can directly process the NAS message, the protocol conversion process in the service process is reduced, and the timeliness is improved.

Example two

Referring to fig. 3, based on the same inventive concept, an embodiment of the present invention provides a mobility management entity MME, which includes a T1 interface 31, at least one protocol stack entity 32, and a processor 33.

The T1 interface 31 may be configured to transmit communication data between the MME and the interfacing TCF, where the transmission protocol configured on the T1 interface includes TCP, UDP, SCTP, and a system queue protocol, that is, the MME may configure multiple transmission protocols for the T1 interface, and may even configure other transmission protocols for the T1 interface, and the other transmission protocols do not include the SIP protocol.

At least one protocol stack entity 32 may be used to carry a preset transport protocol. In practical applications, the protocol stack entities contained in the MME and the TCF may be corresponding. Referring to fig. 4, a protocol stack architecture of a T1 interface between an eMME and a TCF defined in the embodiment of the present invention is shown, where a part labeled as "trans 1" in the figure represents at least one protocol stack entity 32 in an MME, and a part labeled as "trans 2" represents a protocol stack entity corresponding to a T1 interface in a TCF, and it is not necessary to add an SIP protocol stack entity, which is beneficial to reducing and improving the overall complexity of the system.

The processor 33 may be connected to the T1 interface 31 and the at least one protocol stack entity 32, and configured to process an acquired NAS message from a terminal in a non-access stratum, and when it is determined that a message type of the NAS message is a preset message type, pass the NAS message through the T1 interface 31 to the TCF.

Optionally, when determining that the message type of the NAS message is a preset message type, the processor 33 may be further configured to obtain, according to the NAS message, cluster flow session index TPTI information and user call number UDN information of the terminal, and generate, according to the message type, the TPTI information, and the UDN information, header information of the NAS message, where the header information is used to indicate information of the terminal that sends the NAS message, and further, the header information and the NAS message may be simultaneously transmitted to the TCF through the T1 interface.

Therefore, in the embodiment of the invention, the eMMC and the TCF are interacted in a mode of protocol layering stripping and then transparent transmission. That is, in the transport layer, the S1AP layer is run on the SCTP layer, and the NAS layer is run on the S1AP layer, where the MME can strip the SCTP/S1AP after parsing it, obtain the NAS message, and pass it through to the TCF, so the TCF only needs to process the NAS layer message, and the processing efficiency is high.

By using the T1 interface in the mode, the specification can be met, and the SIP protocol development and the service flow conversion of the MME and the TCF are simplified under the condition that the complexity of the TCF and the whole system is not increased.

By using the scheme Of the embodiment Of the invention, the protocol conversion process Of the service process at the T1 interface can be reduced, the timeliness Of the service signaling is improved, the development difficulty and development amount Of the MME and the TCF can be reduced, the stability Of the product is improved, the butt joint Of the T1 interface between the MME and the TCF can be simplified, and the configuration complexity Of the T1 interface between the MME and the TCF and the complexity Of the Internet Of Things (IOT) are reduced.
