Embodiment Construction

[0068] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0069] A mobile station MS network access method provided by an embodiment of the present invention includes:

[0070] The mobile relay station MRS receives the initial ranging request from the MS, allocates first management connection identifiers CIDs for the MS, and sends the first management CIDs to the base station BS;

[0071] The BS receives the first management CIDs, assigns the second management CIDs to the MS, sends the second management CIDs to the MRS, and updates the group information according to the first management CIDs;

[0072] The MRS receives the second management CIDs, establishes a mapping relationship between the first and second management CIDs, and sends the second management CIDs to the MS;

Abstract

The embodiment of the invention discloses three MS network access methods, a wireless communication system, a mobile relay station and a base station. In the first one, MRS and BS distribute CIDs to MS respectively, MRS establishes the mapping relation between two sets of CIDs, MRS transfers mutual information between BS and MS according to the mapping relation, BS updates group information according to the information sent by MRS. In the second one, MRS is connected with BS through a tunnel, MRS distributes CIDs to MS, MRS exchanges information with BS through a tunnel therebetween in a network access flow, BS updates group information according to the information sent by MRS. In the third one, information exchange of the network access flow between MS and MRS is realized, BS is only used for maintaining group information and completing information exchange between MRS and a gateway of an access service network. The methods, the wireless communication system, the mobile relay station and the base station of the invention can reduce air interface signaling spending during the group moving handover process.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a mobile station (MS) network access method, a wireless communication system, a mobile relay station and a base station. Background technique [0002] In order to meet the increasing demand for broadband wireless communication, higher and higher carrier frequencies are used in new protocols and systems. However, the attenuation of radio waves increases with the increase of frequency. Therefore, high carrier frequencies must face the problem of high attenuation, which further limits the coverage of base stations. In order to solve the coverage problem of the base station, it is usually necessary to use a relay station (RS) to enhance the wireless communication signal between the base station (BS) and the mobile station (MS). There is no need for wired transmission between the RS and the BS, and only communicates through wireless links, so it has the advantages of low network d...
