Abstract

A method and system for single-PDP dual-stack serial dialing is provided. A mobile terminal sets a single-PDP dual-stack serial dialing parameter according to a parameter setting command transmitted by a host; then the mobile terminal initiates a PDP activation request to a mobile communication network according to a first dialing instruction transmitted by the host and the configured single-PDP dual-stack serial dialing parameter, acquires activation response information fed back by the mobile communication network, generates dialing response information according to the activation response information, and feeds back the dialing response information to the host, wherein the dialing response information includes cause reference information. And after receiving the dialing response information, the host can acquire a specific condition of the current mobile network according to the cause reference information included in the dialing response information to determine a dialing mode.

First claim

What is claimed is:

1. A method for single-Packet Data Protocol (PDP) dual-stack serial dialing, comprising:
setting, by a mobile terminal, a single-PDP dual-stack serial dialing parameter according to a parameter setting command transmitted by a host;
initiating, by the mobile terminal, a PDP activation request to a mobile communication network according to a first dialing instruction transmitted by the host and the single-PDP dual-stack serial dialing parameter, and acquiring activation response information fed back by the mobile communication network;
generating, by the mobile terminal, dialing response information according to the activation response information, and feeding back the dialing response information to the host, wherein the dialing response information comprises cause reference information; and
determining, by the host, a dialing mode according to the dialing response information;
wherein the activation response information comprises activation results and activation reference information, and wherein generating, by the mobile terminal, the dialing response information according to the activation response information comprises:
judging, by the mobile terminal, whether PDP activation is successful or not according to the activation results, generating dialing success response information or dialing failure response information according to the activation reference information if the PDP activation is successful, otherwise generating the dialing failure response information according to the activation reference information.

2. The method for single-PDP dual-stack serial dialing according to claim 1 , wherein the activation reference information comprises activated type information and denial cause information, and generating, by the mobile terminal, the dialing response information according to the activation reference information when the PDP activation is successful comprises:
judging, by the mobile terminal, whether a type of an activated PDP is that requested by the first dialing instruction or not according to the activated type information, obtaining the cause reference information according to the denial cause information if the type of the activated PDP is that requested by the first dialing instruction, generating the dialing success response information, otherwise judging whether the type of the activated PDP is an Internet Protocol version 4 version 6 (IPv4v6) type or not, obtaining the cause reference information according to the denial cause information if the type of the activated PDP is the IPv4v6 type, generating the dialing success response information, the denial cause information comprising any cause at this moment, otherwise obtaining the cause reference information according to the denial cause information, and generating the dialing failure response information.

3. The method for single-PDP dual-stack serial dialing according to claim 1 , wherein the activation reference information comprises the denial cause information, and generating, by the mobile terminal, the dialing failure response information according to the activation reference information when the PDP activation is failed comprises:
according to the denial cause information, the mobile terminal judges whether a failure cause is that a PDP address or PDP type of the PDP activation request which is initiated according to the first dialing instruction is unknown, recording the cause reference information to be “unknown PDP address or PDP type” if the failure cause is that the PDP address or PDP type of the PDP activation request is unknown, otherwise recording the cause reference information to be “unknown cause”; and
generating, by the mobile terminal, the dialing failure response information according to the recorded cause reference information.

4. The method for single-PDP dual-stack serial dialing according to claim 2 , wherein the first dialing instruction is an Internet Protocol version 4 (IPv4) dialing instruction, and generating, by the mobile terminal, the dialing response information according to the activation reference information comprises:
if the mobile terminal determines that the type of the activated PDP is an IPv4 type according to the activated type information, judging, by the mobile terminal, whether a cause for not activating an Internet Protocol version 6 (IPv6) type is PDP type IPv4 only allowed or not according to the denial cause information, recording the cause reference information to be “PDP type IPv4 only allowed” if the cause for not activating the IPv6 type is PDP type IPv4 only allowed, otherwise judging whether the cause for not activating the IPv6 type is single address bearers only allowed or not, recording the cause reference information to be “single address bearers only allowed” if the cause for not activating the IPv6 type is single address bearers only allowed, also recording the cause reference information to be “single address bearers only allowed” if the denial cause information does not comprise any cause, and generating the dialing success response information according to the obtained cause reference information; and
if the mobile terminal determines that the type of the activated PDP is the IPv4 type requested by the first dialing instruction according to the activated type information, further judging, by the mobile terminal, whether the type of the activated PDP is the IPv4v6 type or not, determining that the denial cause information does not comprise any cause if the type of the activated PDP is the IPv4v6 type, recording the cause reference information to be “success”, generating the dialing success response information according to the obtained cause reference information, otherwise judging whether the failure cause is PDP type IPv6 only allowed or not, recording the cause reference information to be “PDP type IPv6 only allowed” if the failure cause is PDP type IPv6 only allowed, deactivating the PDP of the IPv6 type, which has been activated, otherwise judging whether a cause for not activating the IPv4 type is single address bearers only allowed or not, recording the cause reference information to be “single address bearers only allowed” if the cause for not activating the IPv4 type is single address bearers only allowed, also recording the cause reference information to be “single address bearers only allowed” if the denial cause information does not comprise any cause, and generating the dialing failure response information according to the obtained cause reference information.

5. The method for single-PDP dual-stack serial dialing according to claim 2 , wherein the first dialing instruction is an IPv6 dialing instruction, and generating, by the mobile terminal, the dialing response information according to the activation reference information comprises:
if the mobile terminal determines that the type of the activated PDP is the IPv6 type according to the activated type information, judging, by the mobile terminal, whether the cause for not activating the IPv4 type is PDP type IPv6 only allowed or not according to the denial cause information, recording the cause reference information to be “PDP type IPv6 only allowed” if the cause for not activating the IPv4 type is PDP type IPv6 only allowed, otherwise judging whether the cause for not activating the IPv4 type is single address bearers only allowed or not, recording the cause reference information to be “single address bearers only allowed” if the cause for not activating the IPv4 type is single address bearers only allowed, also recording the cause reference information to be “single address bearers only allowed” if the denial cause information does not comprise any cause, and generating the dialing success response information according to the obtained cause reference information; and
if the mobile terminal determines
