The contents of the present document are subject to continuing work within the TS

35、G and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for inform

36、ation; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been in

37、corporated in the document. Introduction During the course of Release 6, 3GPP TS 43.318 2 (Generic access to the A/Gb interface; Stage 2) and 3GPP TS 44.318 3 (Generic access to the A/Gb interface; Stage 3) were developed that provide access to the 3GPP core network using generic IP connection. Gene

38、ric Access Networks, or GAN, is an extension of GSM/GPRS mobile services into the customers premises that is achieved by tunnelling certain GSM/GPRS protocols between the customers premises and the Core Network over broadband IP network, and relaying them through an unlicensed radio link inside the

39、customers premises. GAN is a complement to traditional GSM/GPRS radio coverage, used to enhance customer premises coverage, increase network capacity and potentially lower costs. Early deployments of GAN are now ongoing. As part of the continuous process of optimizing their network to better meet cu

40、stomer demand a number of operators have indicated a need to further enhance the GAN system. Various goals for such enhancements are documented in section four of the present document. After presentation of the goals, the present document technical alternatives for how to implement such enhancements

41、 to GAN. ETSI ETSI TR 143 902 V13.0.0 (2016-01)73GPP TR 43.902 version 13.0.0 Release 131 Scope The present document contains the results of the feasibility study into the enhancements to Generic Access Networks or GAN. Considerations include overall requirements for enhancements, architectural requ

42、irements, evaluation of potential architectural solutions and alternative architectures. The objective is to identify an architectural solution that best meets the requirements as specified in first section. The feasibility study shall also investigate mechanisms for selecting the most appropriate n

43、etwork domain to serve the user. Existing solutions developed by the 3GPP should be reused as much as possible. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
