Problems solved by technology

[0005] In the prior art, when an MS user signs a contract with the server, at most one APN can be designated as the DefaultAPN, so the control node can only select the subscription information containing the DefaultAPN from multiple sets of data that meet the requirements for activation. No matter how many times the MS user sends The activation request can only reuse the service corresponding to the DefaultAPN after activation. In this scenario, the service type that the MS user can apply is too single; secondly, the control node only configures a LocalAPN for the MS user locally. When activated, MS users can only use the services corresponding to LocalAPN, which also brings about the problem that the types of services that MS users can apply are too single; in addition, in the scenario where there is no subscription information that meets the requirements, the service that is consistent with LocalAPN is preferred. Non-wild card subscription information or the use of pre-designated subscription information also cause the problem that the types of services that MS users can apply are too single

example 1

[0320] Example 1: After the user signs up to the server, there are three sets of subscription information. The APNs used by each of the three sets of subscription information are {APNa, APNb, APNc}, where the DefaultAPN is specified as APNa and APNb, and APNa takes precedence over APNb; secondly, the user is not configured locally LocalAPN. When the same user initiates an activation request in each scenario in turn, the selection scheme of the control node is as follows (here, it is considered that the above subscription information has met the requirements for PDP type and PDP address in the matching requirements, or the relevant requirements are not specified in the matching requirements ):

[0321] Scenario 1: The user initiates an activation request for the first time, and the matching requirement does not specify an APN. After matching, the subscription information containing the APNa with the highest Default priority is finally selected to activate the PDP / PDN context. ...

example 2

[0324] Example 2: After the user signs up to the server, there are four sets of signing information, and the APNs used by each of the four sets of signing information are {APNa, APNb, APNc, *}, where DefaultAPN is APNb, and * is the wild card identifier of the wild card signing information; , There are two LocalAPNs configured locally for the user, namely LocalAPNa and LocalAPNc, where the priority of LocalAPNa is higher than that of LocalAPNc. When the same user initiates an activation request in each scenario in turn, the selection scheme of the control node is as follows (here, it is considered that the above subscription information has met the requirements for PDP type and PDP address in the matching requirements, or the relevant requirements are not specified in the matching requirements ):

[0325] Scenario 1: The user initiates an activation request for the first time, and the matching requirement does not specify an APN. After matching, the subscription information co...

example 3

[0328] Example 3: After the user signs up to the server, there are three sets of subscription information. The APNs used by each of the three sets of subscription information are {APNa, APNb, APNc}, and there is no DefaultAPN. Secondly, there are two LocalAPNs configured locally for the user, namely LocalAPNb and LocalAPNc , where the priority of LocalAPNb is higher than that of LocalAPNc. When the same user initiates an activation request in each scenario in turn, the selection scheme of the control node is as follows (here, it is considered that the above subscription information has met the requirements for PDP type and PDP address in the matching requirements, or the relevant requirements are not specified in the matching requirements ):

[0329] Scenario 1: The user initiates an activation request for the first time, and the matching requirement does not specify an APN. After subscription matching, because there is no DefaultAPN, the subscription information corresponding...

Abstract

The present invention provides a method, device and system for activating a PDP/PDN context. By improving a selection method used for activating a PDP/PDN context, subscription information comprising different APNs is used when the PDP/PDN context is activated in multiple times, and therefore the problem that the types of user application services are not diverse enough due to the repeated use of an APN is solved, so that the range of the service types capable of being used by a user can be expanded, thereby improving the success rate of activations and the satisfaction degree of the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a PDP / PDN context activation method, device and system. Background technique [0002] In the GPRS (General Packet Radio Service, general packet radio service) packet domain core or EPS (Evolved Packet System, evolved packet system) network, control nodes such as SGSN (ServingGPRSSupportNode, serving GPRS support node), MME (MobilityManagementEntity, mobile management entity) mainly complete the grouping Routing and forwarding of data packets, encryption and authentication, session management, mobility management, logical link management, bill generation and output, etc. The control node implements the routing and data forwarding function of service data between MS (MobileStation, mobile station) users and GGSN (GateGPRSSupportNode, gateway GPRS support node) or P-GW (PDNGateway, PDN gateway), which requires PDP (PacketDataProtocolContext, packet Data protocol context) / PDN (Pack...
