The NodeB fast scheduling technology provides high-speed uplink and downlink data transmission; the traditional picture R99 network voice service is the main service, and the data transmission capability is relatively weak. With the rapid development of 3G networks and the surge in data traffic, HSPA CHigh Speed Packet Access (HSPA) technology applications are becoming more and more widely used. How to stratify services in UMTS network deployment has become the focus of operators.

According to the QoS (Quality of Service) requirements, the main types of services of the 3G network are: conversational (streaming), streaming (interactive) and background (background). At present, the voice service of the CS domain (circuit switched domain) and the interaction class of the PS domain (packet switched domain) and the background service are widely used. The service type of the session is characterized by a small end-to-end delay, and the traffic is symmetric or nearly symmetric. For example, the current AMR voice and the vodio phone are session-based services; the traffic type is real-time and has one-way transmission. The characteristics of the real-time requirements are not as strict as the session-type service type, such as the network video stream is a stream-type service; the interactive-type service type refers to the service of the end user and the remote device for online data interaction, characterized by a request The response mode, such as WEB browsing webpage business, database retrieval, MSN, QQ mobile game, navigation and positioning, etc. all correspond to the interactive business type; the background type of business type is characterized by the user having no special requirements for the transmission time, but the packet loss rate High requirements, such as Emai l, SMS, FTP download and other background services.

The prior art is to perform service layering according to different bearer channel types. The layering means that different services are carried on different carriers, the PS service is mainly carried on the HSPA, and the CS voice uses the traditional R99 DCHCDedicated Channel (dedicated channel). channel. In the HSPA application scenario, HSPA is carried on a separate carrier and is separated from R99 to avoid the impact of RSPA service quality (such as data rate, power, etc.) due to HSPA service burst characteristics. User initiates UMTS service First, it is determined whether the service is carried on the HSPA, and if so, the user is camped or redirected to the f 1 carrier where the HSPA is located, otherwise the user is camped or redirected to another carrier f2 corresponding to the DCH. on.

In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: With the diversification of service types, services are layered according to different bearer channel types, and services may affect each other.

The embodiment of the present invention is directed to an application scenario applied to a radio access network, and an application scenario in which a terminal and a radio access network interact, and a radio access network presets a correspondence between a service type and a carrier, and the technical solution of the present invention is described in detail. There are at least three application scenarios in the actual application of the radio access network architecture: When the radio access network includes the base station and the base station controller, the service layering method can be implemented in the base station; when the radio access network includes the base station and the base station control In the case of a device, the method can be implemented in a base station controller; when the radio access network includes only a base station, the method can be implemented in the base station. The network standard that can be used in the embodiments of the present invention includes, but is not limited to, UMTS, LTE (Long Term Evolution), GSM (global system for mobi le communications), CDMA (Code Division Multiple Access, code division). Multiple Access) For example, for a ring TS network, the base station is a Node B and the base station controller is a Radio Network Controller (RNC).

Referring to FIG. 2, an embodiment of the present invention provides a service layering method, which specifically includes:

Step 201: preset a carrier corresponding to the service type.

Specifically, the embodiment of the present invention sets different service layering policies for different services according to the service situation, and the service type with the similar service characteristics is corresponding to one carrier, and one service type may be preset to one carrier, or may be preset. One type of service type corresponds to one carrier.

In the embodiment of the present invention, the existing service is divided into two types of service types: A major class and B major class, and two carriers are preset, and the preset A major service type corresponds to the first carrier, and the B major class. The service type corresponds to the second carrier. The A major service type or the B major service type may include one or more service types. In this case, one or more service types included in the A major service type correspond to the first carrier, B. One or more service types included in the class service type correspond to the second carrier.

In actual applications, each service type included in the two types of service types may be:

A major business types include: Conversational business type.

The B-type service types include: Streaming service type, Interactive business type, and Background business type. That is, since the A major service type corresponds to the first carrier, and the B major service type corresponds to the second carrier, the Conversational service type corresponds to the first carrier, the Streaming service type, the Interactive service type, and the Background service type. Corresponding to the second carrier, the carrier is divided according to the service type.

Or

A major business types include: Conversational business type, Streaming business type.

Type B business types include: Interactive business type, Background business type.

That is, since the A major service type corresponds to the first carrier, and the B major service type corresponds to the second carrier, the Conversational service type and the B Streaming service type correspond to the first carrier, the Interactive service type, and the Background service type. Corresponds to the second carrier.

Or

A major business types include: Conversational business type, Streaming business type, and some special services in the Interactive business type.

The B major service types include: Common Interactive service type, Background business type.

That is, since the A major service type corresponds to the first carrier, and the B major service type corresponds to the second carrier, the Conversational service type, the Streaming service type, and some special services in the Interactive service type correspond to the first one. Carrier, some of the special services in the Interactive service type can be: For example, network voice services, such as skype. A service other than the special service in the Interactive service type is called a normal Interactive service type; a normal Interactive service type and a Background service type correspond to a second carrier.

In practical applications, as the service is widely deployed, a service type may need to be carried on different carriers. The service type can be classified into more major categories, such as three types, and It is assumed that each type of service type corresponds to one carrier, and thus one or more service types included in each major service type respectively correspond to one carrier. The embodiment of the present invention does not limit the specific class of the division,

A major business types include: Conversational business type.

The B major types of services include: Streaming service type.

The C major business types include: Common Interactive business type, Background business type.

Or,

A major business types include: Conversational business type.

The B major types of services include: Streaming service type Some special services in the Interactive business type.

The C major service types include: Common Interactive service type, Background business type. Step 202: The terminal user initiates a first service request.

Among them, the business request can be initiated online, games, QQ, MSN, and the like. In practical applications, the terminal may be a UMTS terminal, an LTE terminal, a GSM terminal, a CDMA terminal, or the like.

Step 203: The core network receives the first service request, determines the first service type corresponding to the first service request according to the first service request, and sends the first service type to the radio access network.

The radio access network in the embodiment of the present invention includes a base station and/or a base station controller. The core network device may be an MSC (Mob i l e Swi tching Center) or a SGSN (Serving GPRS SUPPORT NODE, GPRS service support node).

Specifically, the terminal user initiates a first service request to the core network, and the core network determines a service type corresponding to the first service request, such as a first service type, and sends the service type to the radio access network.

Step 204: The radio access network acquires the first service request to determine the corresponding first service type.

Step 205: The radio access network determines whether the current service type exists in the current terminal. If the second service type exists, step 206 is performed. If not, step 207 is performed.

Determining whether there is currently a second service type. Specifically, determining whether the terminal user is performing another service type other than the first service type, and if other service types other than the first service type are being performed, determining The second service type exists at present. In this case, the service request is actually a combined service, that is, the terminal user is performing two or more service types.

Step 206: The radio access network carries the first service request in the carrier corresponding to the first service type or carries the first service request in the carrier corresponding to the second service type according to the preset correspondence between the service type and the carrier. .

Specifically, the carrier corresponding to the service type and the carrier is preset in step 201, and the carrier corresponding to the second service type is obtained according to the corresponding relationship.

In the actual application, the first service type and the second service type may be the same. For example, if the first service is a web browsing service and the second service is an emai l service, the browsing web service and the emai l service all correspond to the intersect business type. The service type corresponding to the first service is an operator service type, and the service type corresponding to the second service is also an internal service type. Therefore, the first service request is carried in the carrier corresponding to the first service type, and is carried in the first The scheme of the carrier corresponding to the second service type is the same.

In an actual application, the first service type and the second service type may be different. For example, if the first service is a PTT service and the second service is an Internet service, the PTT service corresponds to a conversat ional service type, and the Internet service corresponds to an inter ive service type. , the first service type is different from the second service type.

Preferably, the current first service request is residing in the carrier corresponding to the first service type corresponding to the current first service request, and the current carrier is prioritized, that is, no redirection or handover to another carrier is performed. Step 207: The first service request is carried in a carrier corresponding to the first service type.

If it is determined that the user does not perform other services, it indicates that the first service request only performs one type of service, and the first service request is carried in the carrier corresponding to the first service type.

Optionally, the embodiment of the present invention may preset a default type, where the carrier corresponding to the default type is . When the service request is carried to the carrier, the service request may be preferentially determined to be the default type. If yes, the first service request is carried in the carrier corresponding to the default type; if not, the first service request is carried in the other Carrier, such as f2 or f3. The carrying the first service request in the carrier fl corresponding to the default type includes: residing or redirecting the user to the carrier corresponding to the default type.

The method provided by the embodiment of the present invention performs service layering according to different service types, and presets a correspondence between a service type and a carrier, so that service types with similar service characteristics are carried on the same carrier, and service QoS requirements are similar, minus Smaller interactions between businesses also improve the quality of the business. Example 3

The embodiment is applied to the architecture of the radio access network, and the application scenario of the correspondence between the service type and the carrier is set for the interaction between the terminal and the radio access network, and the technical solution of the present invention is described in detail. There are at least three application scenarios in the actual application of the radio access network architecture: When the radio access network includes the base station and the base station controller, the service layering method can be implemented in the base station; when the radio access network includes the base station and the base station control In the case of a device, the method can be implemented in a base station controller; when the radio access network includes only a base station, the method is implemented in the base station. The network system that can be used in the embodiments of the present invention includes, but is not limited to, UMTS, LTE (Long Term Evolution), GSM (global system for mobi le communications), for example, for a UMTS network, the base station is Node B, the base station controller is a Radio Network Controller (RNC).

Referring to FIG. 3, an embodiment of the present invention provides a method for service layering, which specifically includes:

Step 301: The relationship between the preset cell and the bearer service type.

Specifically, the embodiment of the present invention may carry one type of service in one cell, and may also carry more than one type of service, and the service type that implements different service features is divided into different cells.

As shown in FIG. 4, for example, a CS session service, a V0IP, a PTT, a CS conversational session, and a CS over HSPA service are carried in a cell, and these services have a session-type service feature and have high real-time requirements. The other services (such as ordinary ps services, multimedia messages, etc.) are carried on another cell f2, so that the service characteristics on each cell are similar, and the influence between each other is small, which is beneficial to maximize the utilization of the cell resources.

Step 302: The terminal user initiates a first service request.

Specifically, the service request may be any service request for initiating V0IP, PTT, and the like. In practical applications, the terminal can Think of UMTS terminal, LTE terminal, GSM terminal, CDMA terminal, etc.

Step 303: The radio access network acquires the first service type corresponding to the first service request.

The radio access network can obtain the first service type through the core network.

Specifically, the radio access network includes a base station and/or a base station controller. The radio access network obtains the service type corresponding to the service request according to the preset correspondence between the service and the service type. After receiving the service request of the terminal user, the core network assigns a service type, and notifies the radio access network of the assigned service type, so that the radio access network obtains the service type corresponding to the service request. Here, the core network does not see the information of the application layer, but only determines the type of the service request according to the service request applied by the terminal user, and is not a simple mapping of the service and the service type.

Step 304: The radio access network determines whether the current service type exists in the current terminal. If the second service type exists, step 305 is performed. If the second service type does not exist, step 306 is performed.

Step 305: The radio access network carries the first service request in the cell corresponding to the first service type or the first service request in the cell corresponding to the second service type according to the relationship between the preset cell and the bearer service type. .

Specifically, the cell corresponding to the service type is obtained according to the corresponding relationship, and the cell corresponding to the service type is obtained according to the corresponding relationship.

In an actual application, the first service type and the second service type may be the same. For example, if the first service is a web browsing service and the second service is an emai l service, the browsing web service and the emai l service all correspond to an interactive service type. The service type corresponding to the first service is an interactive service type, and the service type corresponding to the second service is also an interactive service type. Therefore, the first service request is carried in the carrier corresponding to the first service type, and is carried in the second service. The scheme of the carrier corresponding to the type is the same.

In an actual application, the first service type and the second service type may be different. For example, if the first service is a PTT service and the second service is an Internet service, the PTT service corresponds to a conversational service type, and the Internet service corresponds to an interactive service type. The first service type is different from the second service type.

Preferably, the current first service request is residing in the cell corresponding to the first service type corresponding to the current first service request, and the current cell is prioritized, that is, no redirection or handover to another cell is performed.

Step 306: The first service request is carried in a cell corresponding to the first service type.

If it is determined that the user does not perform other services, it indicates that the first service request only performs one type of service, and the first service request is carried in the cell corresponding to the first service type. Wherein, the service request is carried in the first service class The cell corresponding to the type includes: relocating or redirecting the user to the cell corresponding to the first service type.

The method provided by the embodiment of the present invention performs service stratification according to different service types in the cell, for example, the service of the session class resides on the same cell, the service QoS requirements are similar, and the same cell has less influence on each other, and can be improved. The service quality of the operator is more reasonable than the type of bearer channel, which can improve the efficiency of network operation. Example 4

The terminal may be a UMTS terminal, an LTE terminal, or a GSM terminal. Or CDMA terminal, etc.
