Description

Instruction method, device and system for direct message transmission

[1] Technical field

[2] The present invention relates to the field of network communications, and in particular, to a method, an apparatus, and a system for processing a direct transmission message.

[3] Background of the invention

[4] The direct message is UE (User

Signaling between the equipment, the user equipment, and the CN (core network). Since the direct transmission message needs to be transmitted through the access network, the NAS (Non access) is carried in the direct transmission message.

Stratum, non-access layer) IE (information) that information and access networks need to process

Element, information sheet). At UMTS (Universal Mobile Telecommunications

The direct transmission messages in System, Universal Mobile Telecommunications System include: initial direct transmission message, uplink direct transmission message and downlink direct transmission message. The initial direct transmission message and the uplink direct transmission message are uplink messages, which are transmitted by the UE to the core network through the access network.

[5] In the prior art, after the UE initiates a new service, the corresponding direct transmission message processing method is:

[6] The UE in the active state initiates a new service by using the uplink direct transmission message, and the information related to the new service is only reflected in the NAS information included in the uplink direct transmission message, and the information related to the service includes: It is a normal service, an emergency service, or a signaling service.

[7] After receiving the uplink direct transmission message, the network side processes the direct transmission message. Specifically, the RAN on the network side (Radio Access

Network, the radio access network) is configured to process the IE in the direct transmission message, and the IE that can be processed by the RAN side is information that is not related to the initiated service; the CN receives the direct transmission message forwarded by the RAN side, and according to the direct The service information indicated in the NAS transmitting the message indicates that the access network establishes different RBs (Radio Bearer, Radio Bearer) for different services.

[8] In the above method, the RAN side cannot directly perform corresponding processing on the initiated service. Because the RAN side forwards the uplink direct transmission message to the CN side, it does not know the related information of the service at all. The RAN side must wait for the CN side to complete the corresponding service processing. After receiving the downlink message sent by the CN side, the RAN side can obtain the relevant information of the service and start the corresponding service processing. However, in the process of implementing the present invention, the inventors discovered that:

In LTE (Long term

Evolution, long-term evolution) In order to optimize the use of network resources, operators may put certain special services into special frequency layers or RATs (radio access).

Technology, radio access technology) to bear, therefore, the RAN side needs to know some business-related information for business optimization processing. At present, when the UE initiates a new service, and the RAN side cannot support the new service request initiated by the UE in the activated state, the processing flow between the UE, the RAN side, and the CN side is shown in FIG. 1 . It can be seen from FIG. 1 that, in the case that the UE initiates a new service, the RAN side can obtain the related information of the new service initiated by the UE only after receiving the downlink message sent by the CN side, and the RAN side determines according to the obtained related information. If the new service initiated by the UE is not supported for some reason, or the initiation condition of the new service reaches the service restriction condition, the downlink signaling carrying the corresponding subsequent processing information is sent to the UE. Therefore, the processing flow shown in Figure 1 above will bring a relatively large delay to the network processing process, which is not conducive to the expansion of new business requirements.

Similarly, in GSM (Global System

Mobile, Global System for Mobile Communications, CDMA (Code Division Multiple)

Access, Code Division Multiple Access) or WCDMA (Wideband Code Division Multiple)

In the wireless mobile communication system, such as Access and Wideband Code Division Multiple Access, the RAN side must wait for the CN side to complete the corresponding service processing. After receiving the downlink message sent by the CN side, the information about the service can be obtained and the information can be obtained. The corresponding business process processing process leads to a relatively large delay in the business process of the network side, which is not conducive to the development of new business requirements.

An embodiment of the present invention provides a method, an apparatus, and a system for processing a direct transmission message.

The following describes the process of the method in the embodiment of the present invention in detail with reference to the accompanying drawings. As shown in Figure 2, the following steps are included:

[35] Step 2-1: The UE initiates a new service by using the uplink direct transmission message, and the IE included in the uplink direct transmission message carries related information of the initiated service.

[36] The UE in the active state sends an uplink direct transmission message to the CN side through the RAN side, and initiates a new service by using the direct transmission message of the uplink. And adding, in the IE included in the uplink direct transmission message, related information that carries the initiated service, where the related information of the service includes: whether the service is a normal service or an emergency service or a signaling service, and a service type, a priority, and Reasons for establishing a business, conditions related to the business, etc. The IE after adding the relevant information of the above is shown in Table 2 below.

Information related to

Service (Other service related information) The information in the corresponding row is the information about the newly added service.

[40] Step 2-2: The RAN side acquires related information of the service carried in the IE included in the uplink direct transmission message, and performs corresponding processing.

[41] After receiving the uplink direct transmission message sent by the UE, the RAN side forwards the uplink direct transmission message to the peer of the CN side, and obtains information about the service carried in the IE included in the uplink direct transmission message. And handle it accordingly. Therefore, in the embodiment of the present invention, the CN side and the RAN side are changed from the previous serial processing to the parallel processing.

[42] The following example illustrates that the RAN side performs corresponding service processing according to the related information of the service carried in the obtained IE.

[43] In this embodiment, when the RAN side cannot support the new service request initiated by the UE in the active state, the process flow between the UE, the RAN side, and the CN side is as shown in FIG. 3.

[44] When the RAN side obtains the related information of the service carried in the IE included in the uplink direct transmission message, according to the capability limitation of the RAN side or the load limitation of the network, it is determined that the RAN side cannot support the new initiated by the UE. Business request. The reason for the judgment may be: the foregoing new service cannot be provided by the current serving cell or the current serving cell cannot allocate resources for the UE; or, the RAN side determines that the initiation condition of the new service reaches the service restriction condition, for example, The condition that the maximum number of connections or RBs supported by the UE is exceeded.

[45] Then, the RAN determines the subsequent processing flow based on the obtained service information. The subsequent processing procedure includes: instructing the UE to go to a suitable cell to initiate a new service, or release a service with a lower priority, and establish a service with a higher priority. Thereby, the processing delay on the RAN side is saved, and the new one is applied to the above LTE. Business needs.

[46] Of course, in the case that the RAN can establish a connection for the UE, that is, when the RAN side supports the service initiated by the UE, the RAN side can configure the service for the UE in advance, and reduce the delay of the service establishment.

[47] It can be seen that the RAN side of the embodiment of the present invention can directly send the downlink signaling that carries the corresponding subsequent processing information to the UE, and does not need to wait until the downlink message sent by the CN side is received. In this way, the UE's service establishment delay can be effectively shortened, the user's feelings can be optimized, and the network resources can be saved.

[48] A schematic structural diagram of a processing system for a direct transmission message according to an embodiment of the present invention is shown in FIG. 4, and includes the following modules:

[49] The UE is configured to send an uplink direct transmission message to the RAN side device, and carry the related information of the initiated service in the IE included in the uplink direct transmission message. The method includes: an uplink direct transmission message construction module and an uplink direct transmission message sending module, where the uplink direct transmission message construction module is an optional module.

[50] The uplink direct message construction module is configured to construct an uplink direct transmission message of the initiating service, and set related information of the initiated service in the IE included in the uplink direct transmission message;

[51] The uplink direct transmission message sending module is configured to send, to the RAN side device, an uplink direct transmission message, such as the uplink direct transmission message construction module.

[52] The RAN side device is configured to obtain related information about the service carried in the IE, and perform corresponding processing according to the related information of the service. Including: business related information acquisition module and business processing module.

[53] The service-related information obtaining module is configured to acquire information about the service initiated by the UE from the IE included in the uplink direct transmission message sent by the received UE.

[54] The service processing module is configured to perform corresponding processing according to the related information of the service acquired by the service related information acquiring module.

[55] The service processing module may specifically include:

[56] a first processing module, configured to determine, according to the obtained related information of the service, that the RAN side cannot be

When the UE establishes a connection, sending corresponding subsequent processing information to the UE; and/or,

[57] The second processing module is configured to perform service-related configuration for the UE when the RAN side can establish a connection for the UE.

[58] In the case that the first processing module is included, determining that the RAN side cannot establish a connection for the UE The method is as follows: determining that the RAN side cannot support the service initiated by the UE, or the service restriction condition is met when the service is initiated.

The method and system according to embodiments of the present invention are applicable to LTE, GSM (Global System)

Mobile, Global System for Mobile Communications, CDMA (Code Division Multiple)

Access, Code Division Multiple Access) and WCDMA (Wideband Code Division Multiple)

Access, broadband code division multiple access) and other wireless mobile communication systems.

[60] In summary, the embodiment of the present invention solves the problem that the RAN side cannot support the new service request initiated by the UE due to capability or load or other reasons, or the new service is initiated to meet the service restriction condition, and the RAN side can be guaranteed. And the corresponding processing is performed, that is, when the RAN receives the content carried in the IE of the direct direct transmission message, the corresponding processing is started. When the CN sends the corresponding processing (establishing RB or other) to the RAN according to the content carried in the NAS, the RAN can directly reply to the CN, which saves negotiation and processing between the two, thereby saving the delay in establishing the service of the UE. .
