Embodiment 1

[0029] see Figure 1~2 , a method for guaranteeing packet service bandwidth applicable to a satellite mobile communication system, comprising the following steps

[0030] Step 1. When the satellite terminal user activates the packet data service, he first sets the user's QoS information through the service opening system, and marks it as Qos1 information;

[0031] Step 2, the service opening system sends the user QoS1 information to the core network, and the core network stores the QoS1 information in the HLR;

[0032] Step 3, before the satellite terminal user initiates a packet service application, configure the Qos information of the packet data service applied for this time through the interface locally, and mark it as Qos2 information;

[0033] Step 4, when the core network receives the user's packet service connection request, check and compare the Qos2 of the packet data service initiated by the user through the air interface and the service Qos1 opened by the user thr...

Embodiment 2

[0042] see Figure 1~2 , a method for guaranteeing packet service bandwidth applicable to a satellite mobile communication system, comprising the following steps

[0043] Step 1. When the satellite terminal user activates the packet data service, he first sets the user's QoS information through the service opening system, and marks it as Qos1 information;

[0044] Step 2, the service opening system sends the user QoS1 information to the core network, and the core network stores the QoS1 information in the HLR;

[0045] Step 3, before the satellite terminal user initiates a packet service application, configure the Qos information of the packet data service applied for this time through the interface locally, and mark it as Qos2 information;

[0046] Step 4, when the core network receives the user's packet service connection request, check and compare the Qos2 of the packet data service initiated by the user through the air interface and the service Qos1 opened by the user thr...

Embodiment 3

[0055] see Figure 1~2 , a packet service bandwidth guarantee method suitable for satellite mobile communication systems. Taking Tiantong-1 satellite mobile communication system as an example, the system is currently in the commercial operation stage. With the launch of Tiantong-1 02 and 03 satellites, Overseas coverage has been achieved. Due to the limited system bandwidth, the number of concurrent packet data users that can be supported is relatively low. After the invention is applied, the ability to support packet data services for satellite terminals can be significantly improved. The specific modification contents are:

[0056] 1) Satellite terminal: For satellite terminals, it is necessary to develop a human-computer interaction interface that supports users to apply for service type and service rate input, and in the packet data service process, transmit the service type and service rate to the gateway station through the air interface;

[0057] 2) Service opening sy...

Abstract

The invention discloses a packet service bandwidth guarantee method suitable for a satellite mobile communication system, which comprises a satellite terminal, a service opening system, a gateway station core network and a gateway station GSC, and creates a shared service type and an exclusive service type. The method has the advantages that resource occupation in a satellite mobile communication system is divided by an exclusive method and a sharing method, an overall packet service bandwidth guarantee strategy is designed, the problems that under the condition that satellite resources are limited, packet service users are small in concurrence amount, and the system capacity is limited are solved, and the service quality of the satellite mobile communication system is improved. The support capability of the system for grouped data users is improved, the user concurrency capability of system data services can be improved, successful access and service use of more satellite users are guaranteed, and the flexibility of the system is improved.

Description

technical field [0001] The invention relates to a packet service bandwidth guarantee method, in particular to a packet service bandwidth guarantee method suitable for a satellite mobile communication system, and belongs to the satellite communication technical field. Background technique [0002] The satellite mobile communication system can provide users with large-scale, long-distance, flexible voice, short message, and packet data services through satellite relay and forwarding, and has great advantages in comprehensive coverage, emergency communication, and universal services. [0003] For existing published patents [0004] The patent number is: CN103701722A, a network bandwidth allocation method. The technical problem to be solved is that related technologies can only distinguish traffic according to IP, port and other information and make simple QoS policies. In such an environment, this traditional bandwidth The management method will seriously fail and fail to achi...
