Embodiment 1

[0020] Embodiment 1 of the present invention provides a network negotiation method, such as figure 1 shown, including the following steps:

[0021] S101. The terminal activates a session management protocol, and sends a first session negotiation message to a network session management entity, where the first session negotiation message includes a record that the terminal supports the first version of the network protocol.

[0022] S102. When the terminal receives the session negotiation failure message sent by the network session management entity, set the network protocol version as the second version, and deactivate the session management protocol. Optionally, the deactivating the session management protocol includes clearing content related to the first session negotiation message in the session management protocol.

[0023] S103. The terminal activates the session management protocol again, and sends a second session negotiation message to the network session management e...

Embodiment 3

[0039] The terminal 30 provided by the embodiment of the present invention, such as image 3 As shown, it includes: a first negotiation unit 31 , a session negotiation failure message receiving unit 32 , a reconfiguration unit 33 , and a second negotiation unit 34 .

[0040] The first negotiation unit 31 is configured to activate the session management protocol, and send a first session negotiation message to the network session management entity, where the first session negotiation message includes a record that the terminal supports the first version of the network protocol.

[0041] The session negotiation failure message receiving unit 32 is configured to receive the session negotiation failure message sent by the network session management entity, and send a configuration instruction to the reconfiguration unit.

[0042] The reconfiguration unit 33 is configured to receive the configuration instruction sent by the session negotiation failure message receiving unit, set th...

Embodiment 4

[0046] The EVDO network terminal 40 provided by another embodiment of the present invention, such as Figure 4 As shown, it includes a first negotiation unit 41 , a session negotiation failure message receiving unit 42 , a prompt unit 43 , a user instruction receiving unit 44 , a reconfiguration unit 45 , and a second negotiation unit 46 .

[0047] The first negotiation unit 41 is configured to activate the session management protocol, and send a first session negotiation message to the network session management entity, where the first session negotiation message includes a record that the terminal supports the first version of the network protocol.

[0048] For example, under current technical conditions, for a terminal capable of supporting Rev.B version, the first session negotiation message may include a record that the terminal supports Rev.B version, where the terminal supports the Rev.B version record, It is the version information, that is, the version number of the p...

Abstract

The embodiment of the invention provides a method and terminal for network consultation. The problem of frequently failed session consultation caused by the terminal which cannot be identified by a network can be solved. The method comprises the following steps of: activating a session management protocol by the terminal; sending a first session consultation message, which contains a record of a first version network protocol supported by the terminal, to a network session management entity; when a session consultation failed message sent by the network session management entity is received by the terminal, setting the version of network protocol as a second version and deactivating the session management protocol; and reactivating the session management protocol by the terminal and sending a second session consultation message to the network session management entity, wherein the second session consultation message contains the record of a second version network protocol supported by the terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a network negotiation method and a terminal. Background technique [0002] In the evolution of CDMA 2000 EVDO (Code Division Multiple Access 2000Evolution Data Only, which is a stage of a path of CDMA2000 evolution), there are currently three versions, from low to high, respectively EVDO Rev.0, Rev.A, Rev.B . At present, the terminals and networks on the market are mainly Rev.A, and some operators have begun to deploy Rev.B networks, and manufacturers are also launching Rev.B terminals one after another. [0003] At present, the Rev.B network is basically only covered in some urban hotspots, and most of them are Rev.A networks. According to the protocol design, the Rev.B terminal and the Rev.A network are compatible with each other, which means that the Rev.B terminal can also be used normally under the Rev.A network. [0004] In this way, users using Rev.B terminals can switch betwe...
