Problems solved by technology

[0012] The above two methods, the first method limits the content of Personality, the source / target AN of switching needs to limit the protocol subtype used by each set of Personality; the second method is not easy to expand the protocol, when adding a new set of Personality or When adding a new sub-protocol, it needs to provide a large modification to support
These two session storage methods make it difficult to realize interconnection between networks of different equipment manufacturers.
[0013] To sum up, the existing session information storage mechanism limits the handover conditions, that is, the source-side AN must meet the conditions of the target-side AN to organize session information, so that the session information transmitted by the source-side AN to the target-side AN can be used by the target Side AN accepts

Embodiment Construction

[0045] The present invention proposes a general session storage mechanism for the RevA / RevB version network and simultaneously meets the requirements of Rev0, RevA and RevB terminals.

[0046] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0047] The principle of the Session storage method of the present invention is:

[0048] Since the Personality content negotiated by the terminal under the source-side AN is completely determined by the version of the terminal and the version of the source-side AN, for different terminal versions and source-side AN versions, the negotiated Personality may have the following combinations:

[0049]

Rev0 Network

RevA Network

RevB Network

Rev0 terminal

【0】

【0】

【0】

RevA terminal

【0】

[A] or [0, A]

[A] or [0, A]

RevB terminal

【0】

[A] or [0, A]

[B] or [0, B] or [...

Abstract

The invention provides a session information storage method and access network equipment, wherein the method comprises the following steps that: a target side access network obtains all personality according to protocol property information; and the target side access network distributes a storage area for each set of personality obtained, stores the properties of sub-protocols of each set of personality in the corresponding storage area, and the storage structure of each set of personality is determined according to all levels of protocols of each set of personality and the corresponding sub-protocols of each level of protocol. The invention determines the structural organization of Session information according to the mapping relationship between the protocol types and the sub-types of the personality, can be compatible with the Session information results which may be negotiated between different versions of AT and AN, can support the flexible Session negotiation in the largest scope, and can meet various requirements on network construction.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for storing session information Session and an access network device adopted by a RevA / RevB version terminal of CDMA 1xEVDO to meet smooth switching between RevA / RevB networks. Background technique [0002] CDMA 1xEVDO introduces a negotiation mechanism in the implementation of air interface technology. The air interface protocol is divided into seven layers, each layer contains multiple protocols, and each protocol has different sub-protocols. Before the terminal uses the network, it must first complete the session information session negotiation of the air interface. Since EVDO has RevA and RevB versions on the evolution roadmap, terminals of different versions negotiate different session contents under different versions of the network. For example, a RevA terminal can negotiate [Rev0, RevA] two sets of attributes on the RevA network (the protocol is described as ...
