Problems solved by technology

[0004] In the satellite communication system, the number of terminals supported by the broadband communication system is limited, and it is not easy to compete for resources. However, the resource planning method of the multi-user narrowband communication system basically refers to the 2G / 3G baseband implementation method of 3GPP, and the signaling channel resource Different from traffic channel resources, this implementation method is very prone to insufficient signaling channels and idle traffic channels in multi-user long-delay application scenarios

Embodiment 1

[0023] Embodiment 1: Satellite air interface resource allocation and recovery process based on shared resource pool

[0024] The allocation of the satellite wireless air interface shared resource pool is closely combined with the satellite air interface communication process, such as figure 1 As shown, this embodiment provides the communication process between the satellite terminal and the radio resource controller as well as the channel allocation and recovery process, and the specific steps are as follows:

[0025] (1) The radio resource controller first performs radio resource pool planning, and plans a common channel resource pool and a dedicated channel resource pool for each beam;

[0026] (2) The radio resource controller establishes a broadcast channel, a random access channel, and an access authorization channel in each beam according to the resource planning in the common channel resource pool; wherein, the broadcast channel is a unidirectional downlink channel, and...

Embodiment 2

[0033] Embodiment 2: Channel resource pool division and resource block cutting method based on shared resource pool

[0034] (1) Firstly, the satellite air interface wireless resources are divided into public channel resource pools and dedicated channel resource pools.

[0035] (2) Five resource blocks are planned in the common channel resource pool, resource block 1 is used for broadcast channel, resource block 2 and resource block 3 are used for random access channel, resource block 4 and resource block 5 are used for accessing authorized channel. All 5 channels are established and used at one time when the beam is established.

[0036] (3) Resources in the dedicated channel resource pool are allocated dynamically according to the communication process of the satellite terminal. Resource block 1 is used for the signaling channel of satellite terminal A, resource block 2 is used for the traffic channel of satellite terminal A, resource block 3 is used for the signaling chann...

Abstract

The invention discloses a satellite air interface resource allocation and recovery method based on a shared resource pool, and belongs to the technical field of satellite communication. According to the method, a new satellite resource planning and distribution method is provided, signaling resources and service resources are uniformly planned into a special channel resource pool, dynamic cutting and distribution are carried out along with resource application, and the resources are recycled into the resource pool after being used. According to the method, the user capacity under the condition that satellite air interface resources are limited can be effectively improved, and the phenomenon that network access cannot be achieved or location area updating cannot be achieved due to the fact that a satellite terminal competes for signaling channel resources is relieved. The method can be applied to air interface resource allocation optimization of a Tiantong-1 satellite mobile communication system and air interface resource allocation management design of similar systems.

Description

technical field [0001] The invention relates to a method for allocating and recovering satellite air interface resources based on a shared resource pool, and belongs to the technical field of satellite communication. Background technique [0002] Shared resource pool technology has been applied in the field of Internet and terrestrial cellular mobile communication. In the field of the Internet, cloud computing is a typical application of the idea of ​​shared resource pools. Computing resource pools or storage resource pools are realized through the sharing of computing power and storage space of multiple servers. In the field of terrestrial cellular mobile communications, the internal boards of the base station equipment share the processing resources of multiple boards through redundant configuration. [0003] In terms of wireless resource management, the wireless resources of base stations of terrestrial cellular mobile communication systems 2G and 3G are multi-color mult...
