Description

06 001927 How to implement differentiated services

Technical field

The present invention relates to the field of mobile communication technologies, and in particular, to a method for implementing differentiated services in a mobile communication system. Background of the invention

In the process of continuous development of mobile communication technology, in order to use wireless resources more effectively and provide differentiated services with different quality of service for users with different needs, operators need to segment user groups by defining user priorities and business priorities. Level, and the priority of the user service combination, etc., divide the user groups with different needs into different levels, and give different service strategies for different priority users in terms of resource reservation, use, preemption, and quality of service. , enabling them to obtain different quality of service experience while realizing the effective allocation and use of network resources.

Currently, the Enhanced Multi-Level Precedence and Pre-emption Service (eMLPP) supplementary service is defined in the 3rd Generation Partnership Project (3GPP) protocol, which can support user priority signing and resources. Preemption. For the user who has subscribed to the user priority, the subscription information will be stored in the home location register (HLR), and the HLR will transfer the priority information of the user subscription to the mobile switching center (MSC) through the process of inserting the user data; The assignment request and the handover request pass the priority information of the user to the radio network controller (RNC); after that, the MSC and the RNC perform resource allocation according to the priority information of the user. During this time, the MSC and RNC allow high-priority users to preempt the resources of low-priority users.

It can be seen that eMLPP can implement differentiated services for different users through user priority signing, but eMLPP service is only applicable to third-generation mobile communication systems. 7

(3G) HLR, MSG, and the original second-generation mobile communication system (2G) will not be able to directly deploy eMLPP services.

In addition, the eMLPP service does not support the setting of the priority of the service, and the priority of the primary and the called interaction cannot be set. The information related to the current service, such as the location, time, and roaming type of the user, cannot be determined. The user's service strategy. Summary of the invention

In order to solve the above technical problem, the present invention provides a method for implementing a differentiated service, which can determine a service policy for the user according to related information of the user initiated service, and can be applied to both the third generation mobile communication system and the second. Generation mobile communication system.

The method for implementing the differentiated service of the present invention comprises the following steps:

The MSC determines the user group number of the user priority group in which the user accessing the network is located; the MSC related to the accessed service obtains the priority information of the service according to the user group number of the user associated with the service, and obtains the priority information. Information is sent to the base station control device associated with the service;

The MSC and the base station control device associated with the service perform resource allocation based on the priority information. Level differentiated services, and can be applied to both third-generation mobile communication systems and second-generation mobile communication systems. BRIEF DESCRIPTION OF THE DRAWINGS

1 is a flowchart of a method for implementing a differentiated service according to a preferred embodiment of the present invention; FIG. 2 is a flowchart of a method for implementing a differentiated service according to another preferred embodiment of the present invention; 01927

Mode for carrying out the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

1 shows a flow of implementing a differentiated service according to a preferred embodiment of the present invention. The method is applicable to a network having a user priority subscription capability, and users in the network have already subscribed to a user priority.

As shown in FIG. 1, the implementation method of the differentiated service of the present invention mainly includes the following steps: A. After a user accesses the network, the MSC obtains the user priority subscription information subscribed by the user from the HLR.

The method described in this embodiment can provide multiple user priority subscription modes. For example, for a normal user, in the second generation mobile communication system, the user can pass a category or a supplementary service code (SS-CODE). ) for user priority signing; in third-generation mobile communication systems, users can use User, Priority Management (CS Allocation/Retention Priority), SS-CODE > eMLPP for user priority Level signing; for 2G or 3G smart users, you can use the service key (ServiceKey) to achieve user priority signing.

The category value ranges from 0 to 255, and the reserved E0 ~ FE can be extended by the operator. By assigning different Category values to different priority users, the user priority subscription of the Category mode is implemented; eMLPP defines Level 7 priority, where priority 0 ~ 4 can be used for user priority signing; Priority of Level in CS Allocation/Retention Priority ranges from 0 to 15, where 1 ~ 14 can be used for user priority Signing up; SS-CODE can be extended by the operator from F1 to FF, which can be used for user priority signing.

After the user performs user priority signing, the user priority subscription information corresponding to the user is stored in the corresponding HLR. In this way, after the user accesses the network, the MSC will pass the bit. The update message requests the HLR to subscribe to the user priority subscription information of the user; and then, the HLR sends the user priority subscription information to the MSC by inserting the user data message.

Here, the user priority subscription information includes: a subscription mode of the user and a subscription value.

B. The MSC determines the user group number of the user priority grouping according to the pre-configured mapping table of the user priority and the user group number and the user priority subscription information corresponding to the user.

A mapping table of user priority subscription information and user group number is pre-configured in the MSC, as shown in Table 1.

Table 1

As can be seen from Table 1, the mapping table contains the following items: subscription type, subscription value, mask, user group, and user group number. Since the operator may configure to use only a few bits in the subscription value cell instead of all to represent the user priority information, the operator assigns a mask to each subscription type, and the MSC corresponds to the subscription value by The mask is operated and operated to obtain the true user priority subscription information. Therefore, only the bits corresponding to the mask 1 in the subscription value are used to identify the subscription information of the user priority.

As can be seen from Table 1, the MSC can obtain the user priority of the user according to the user priority subscription information mapping including the subscription type and the subscription value corresponding to the user by searching the table. The user group number of the level grouping.

It should be noted that Table 1 only shows a specific example of the mapping table. Specifically, how many packets can be divided into users and how to divide them will depend on the operator's priority policy and the degree of subdivision of users.

C. When there is service access, the MSC related to the service is based on the related information of the service.

Service ^: quantity level, obtain the business priority information and service quality information of the service.

The service priority information and the service quality information may be generally referred to as priority information of the service.

The MSC associated with the service in this step includes the calling MSC and the called MSC of the service.

The information related to the current service includes: a mobile origination (MOC) and a mobile termination (MTC) indication, an emergency mode indication for indicating a special situation or an emergency, and an office direction indication indicating a call incoming source or a outgoing destination. , location group number, time period, International Mobile Subscriber Identity Number Segment (IMSI) category, service type, called number segment, etc.

The MSC is pre-configured with a mapping table of service-related information and correspondence between user group numbers and service priorities and service quality levels, as shown in Table 2. The calling party is called the MOC. The IMSI service is used by the user user and the user. The type of the service is called the service group number. The MTC group number is the quality indicator.

level

1 1 MO No Local Voice 1 1

3 3 MO No local data 3 3 3 3 MO is local 2 2

3 MO No 110 1 2

3 MO No 22:00-7:00 MVNO 2 1

3 MO No 4 2 3

3 3 MO No 2 Local Data 2 3

2 MO No 2 1

4 MO No 3 3

5 MO No 3 3 Table 2

Note: MO in the table indicates mobile origination; MVNO indicates mobile virtual carrier.

As can be seen from Table 2, the MSC can directly obtain the priority of the current service and the quality of service level according to the current service information and the user group number of the currently associated user.

The service priority defines priority information such as priority, preemption, and queuing attributes of the current service, as shown in Table 3. The quality of service level defines services such as codec, rate set, and other quality of service (QoS) attributes of the current service. Quality information, as shown in Table 4.

table 3

The priority level is used to indicate the priority of the current service allocation of the RNC or BSC on the access side.

Quality of Service Maximum Bit Rate Guaranteed Bit 2G Codec 3G Codec Rate

1 122kbps 76 kbps Enhanced Full Rate AMR 7.95-12.2

2 96 kbps 45 kbps half rate AMR 4.75-7.95

3 122 kbps 76 kbps full rate AMR 6.7-10.2 Table 4

Among them, AMR represents an adaptive multi-rate codec mode.

D. The MSC related to the service sends the service priority information of the current service and the service quality information to the base station control device related to the current service.

The service priority information described in this step includes at least: a priority level, a preemption capability, a preemptive vulnerability, and a queuing attribute of the service. The service quality information includes at least: a maximum bit rate, a guaranteed bit rate, and a codec mode attribute.

The base station control device described in this step is an RNC for the third generation mobile communication system and a base station controller (BSC) for the second generation mobile communication system.

In the third generation mobile communication system, if the current service call is a call within the exchange, the MSC will directly maintain the priority/maximum bit rate in the RAB-ASSIGNMENT-REQ message. / Guaranteed Bit Rate (ARP/MBR/GBR) The cell sends the service priority of the current service and the quality of service information to the calling and called RC.

If the current service call is a call between the exchanges, the calling MSC may further prioritize the service priority and quality of service of the current service by using multiple priority and preemption (MLPP) cells in the start address message (IAM). Send to the called MSC. At this time, the called MSC can directly obtain the service priority and service quality information of the current service from the calling MSC. The called MSC can also obtain the priority and quality of service information of the current service by the method described in step C, and then notify the called RNCo through the ARP/MBR/GBR cell in the RAB-ASSIGNMENT-REQ message.

In the second generation mobile communication system, the MSC will pass the assignment request. (ASSIGNMENT-REQ) The Priority (Priority) cell in the message sends the service priority of the current service and the quality of service to the calling and called BSCs.

If during the current service, the user switches to the exchange of the third generation mobile communication system, including the handover from the second generation mobile communication system to the third generation mobile communication system and the internal generation of the third generation mobile communication system. If the handover is performed, the MSC where the user originally located transmits the service priority and the quality of service information to the RNC to which the handover is performed through the ARP/MBR/GBR cell in the RELOCATION-REQ message.

If the current service is in progress, the user has an internal handover to the exchange of the second generation mobile communication system, including the handover from the third generation mobile communication system to the second generation mobile communication system and the internal generation of the second generation mobile communication system. If the handover is performed, the MSC where the user originally located will deliver the service priority and quality of service information to the BSC to be switched to by the Priority cell in the handover request (HANDVOER-REQ) message.

If the user's handover to the third generation mobile communication system or the handover to the second generation mobile communication system during the current service is a handover between the exchanges, in the handover process, the original MSC of the user will first prepare through the handover. The Access Network Application Protocol Data Unit (AN-APDU) cell in the "Prepare Handover" message delivers the service priority and quality of service information to the MSC to be handed over, and the MSC notifies that the handover is to be performed by the above method. To the RNC or BSC.

E. The MSC and the base station control device related to the current service perform resource allocation according to the service priority of the current service and the service quality information, and implement differentiated services.

After obtaining the service priority and the service quality information of each service, the MSC and the base station control device may provide QoS attributes such as codec and rate set for different services according to the priority level, preemption, and queuing attributes of each service. Different access speeds and quality of service to provide differentiated services.

In addition, in network resources, for example, system processing capabilities, relay resources, bearer quality, When the congestion occurs, the MSC preferentially denies the service with the lower priority of the service according to the set service policy, and prioritizes the successful implementation of the service with the highest service priority.

It can be seen that the method described in this embodiment can not only implement differentiated services for different users, but also implement differentiated services for different services according to user information such as the location, time, and roaming type of the user. service. In addition, the method described in this embodiment is applicable not only to the third generation mobile communication system, but also in the middle of the second generation mobile communication system, if the user does not perform user priority signing, or if the network itself does not have the contracting capability. , the difference can not be achieved.

In order to provide a differentiated service for a user who does not perform user priority signing, another preferred embodiment of the present invention provides a method for implementing a differentiated service, as shown in FIG.

The method described in this embodiment mainly includes the following steps:

a. After the user accesses the network, the MSC determines the user group number of the priority group of the user where the user is located.

The method for determining the user group number of the user in this step includes the following two types:

First, the MSC determines the user group number of the user according to the IMSI number segment of the user. In this case, the MSC is pre-configured with the corresponding relationship between the user's IMSI number segment and the user group number, as shown in Table 5. Through the correspondence between the user IMSI number segment and the user group number, the MSC can directly search for the user group number that determines the priority grouping of the user where the user is located, and at the same time, obtain the user roaming type of the user and the operator to which the user belongs.

table 5

It should be noted that Table 5 only gives a specific example of the mapping table, specifically how Grouping users according to the IMSI number segment of the user depends on the priority policy set by the operator. Second, the MSC allocates a default user group number to a user who has not subscribed to the user priority according to the pre-configured default user group number.

In a preferred embodiment of the invention, the default user group number configured for a user who has not subscribed for user priority is 3.

b. When there is a service access, the MSC related to the service is related to the current service and the user group number of the related user determines the service priority and service quality of the current service.

c. The MSC related to the service sends the service priority of the current service and the quality of service information to the base station control device related to the current service.

d. The MSC and the base station control device related to the current service perform resource allocation according to the service priority of the current service and the service quality information, and implement differentiated services.

The implementation methods of steps b to d in this embodiment are the same as the implementation methods of steps C to E.

It can be seen that the method described in this embodiment not only has the advantages of the previous embodiment, but also implements differentiated services for different service priorities in a network that does not have the user priority signing capability, and implements network resources. Effective allocation and use.
