Description

Method and device for dynamically adjusting packet data protocol subscription data during roaming
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for dynamically adjusting packet data protocol subscription data during roaming.
Background
A GPRS (General Packet Radio Service) network and a UMTS (universal Mobile Telecommunications System) PS (Packet Switched Domain) network based on GSM (Global System for Mobile Communication) can provide a Mobile data Service for a user. The user can use a mobile device such as a mobile phone, a PAD, etc. to connect to the internet or a proprietary network through a data service to move office, browse web pages, view e-mails, play online games, listen to online music, or watch online videos.
The GPRS and UMTS PS domain network architecture is shown in figure 1. The user equipment is connected to a BSC (base station Controller) (or RNC (Radio Network Controller)) through a wireless interface, and then, after it is determined that a user can use a service provided by the Home Network, it is connected to a service Network required by the user through a GGSN (Gateway GPRS Support Node) device in an SGSN (Serving GPRS Support Node) and an HLR (Home Location Register) connected to a core Network, and then the user can complete a desired service.
In GPRS and UMTS PS domain networks, which Data network a subscriber can connect to and what level of service is available is determined by the subscriber's PDP (Packet Data Protocol) subscription Data. The PDP subscription data is composed of parameters such as a context ID, an APN (Access Point Name), a charging characteristic, routing subscription data, and QoS (Quality of Service) subscription data. The context ID is a sequence of numbers identifying the PDP, ranging from 1 to 50, which are not allowed to repeat. The APN is the access point name, representing the name of the current connection. The charging subscription data indicates how the user is charged. The QoS parameters are used to determine the service level available to the user, such as the rate of access, the packet loss rate, etc.
The route signing data consists of PDP address type, address distribution option and corresponding address, and is used for searching the network accessed by the user. In the current 3GPP (3rd Generation Partnership Project) protocol, the PDP address types include both dynamic allocation and static allocation; the address allocation options include two types, namely PPP and IP, wherein the IP types are divided into three types, namely IPv4, IPv6 and IPv4/v 6. In general, each SGSN should support dynamic and static allocation, but not the same for address allocation options. All SGSNs support IPv4 types, some newer SGSNs will support IPv6, and some more advanced SGSNs will simultaneously support IPv4/v 6.
According to the 3GPP protocol, each subscriber can subscribe to a maximum of 50 PDP subscription data, which are stored in HLR network elements. When a subscriber registers in the GPRS/UMTS PS domain network, the HLR transmits it to the SGSN.
When the mobile device requires to use the data service, the mobile device sets the requested PDP type according to its own capability (supporting IPv4, IPv6, IPv4v6) and then sends it to the SGSN together with other parameters.
After receiving the request sent by the mobile device, the SGSN needs to determine which PDP should be used to serve the user, considering three factors, namely, the type supported by the mobile phone, the type supported by the SGSN, and the subscription type of the user.
However, currently, the HLR transmits all the PDP subscription data signed by the user to the SGSN, and in this transmission process, the HLR does not consider the support capability of the SGSN, and the inserted PDP subscription data is not adjusted for the support capability of the SGSN; part of PDP subscription data which is not supported by SGSN is inserted, thereby causing
SGSN needs to save useless PDP subscription data, which increases memory occupation; the useless PDP subscription data increases the workload of the SGSN in selecting the available PDP, and reduces the processing efficiency; also the SGSN may select an unavailable PDP resulting in traffic anomalies.

Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.
Fig. 1 shows an outline of GPRS and UMTS PS domain network architectures, in which the various elements and the interfaces established between them are shown, the GPRS-labeled part of the figure is the GSM network data part network element, and the UMTS PS domain network element is the same as GPRS. The bss (rns) part of the figure belongs to the radio side, and the user's equipment is connected to the mobile network via the radio interface they provide. SGSN, HLR, GGSN belong to mobile core network part, used to support user device to use different network, and user device is connected to Internet and other service network through GGSN.
When a user needs mobile data service, the handheld device is connected to the BTS/RNC through a wireless interface and then is accessed to the SGSN. The SGSN sends a registration request to the HLR, and the HLR inserts the subscription data (including the PDP subscription data) of the user to the SGSN. The SGSN selects proper GGSN to serve the user according to the capability of the hand-held device, the SGSN supporting capability and the PDP subscription data inserted from the HLR. The user may then receive data services via the handheld device. Since the architecture and the user equipment implementing the interconnection with the network via the architecture are well known to those skilled in the art, the technical details of the interfaces, protocols, etc. are not described herein in more detail.
Based on the network architecture, various embodiments of the method of the present invention are presented.
Please refer to fig. 2, which is a flowchart illustrating a method for dynamically adjusting a pdp subscription data during roaming according to a first embodiment of the present invention. As shown, the method includes:
step S101: a data service request initiated by a terminal via a serving general packet radio service support node SGSN is received.
The basis for the implementation in this solution is that the SGSN and the mobile terminal have registered the relevant PDP information in the HLR. The data service request is initiated to SGSN by user through mobile terminal, then the SGSN initiates position updating request information to HLR, which contains own address signing data. As mentioned above, the HLR inserts the subscription data (including the PDP subscription data), that is, the dynamic adjustment process of the PDP subscription data described in this embodiment is completed in the HLR.
Step S102: and acquiring the Packet Data Protocol (PDP) subscription data of the terminal, and acquiring the PDP support capability pre-registered by the SGSN.
In the prior art, all the PDP subscription data need to be directly inserted, and then the SGSN selects the PDP subscription data to realize correct insertion and data transmission. If the PDP subscription data is not supported by the SGSN, the connection will fail or the PDP subscription data will need to be handed over.
Step S103: and correcting the PDP subscription data according to the PDP support capability of the SGSN.
In order to realize the universal use of the PDP subscription data to the SGSN, before the PDP subscription data is inserted into the SGSN, the HLR realizes the adjustment of the PDP subscription data, so that all the inserted PDP subscription data are within the PDP support range of the SGSN. And the HLR compares the PDP signing data with the PDP support capacity of the SGSN one by one, and if the PDP signing data outside the PDP support capacity range of the SGSN exists, the PDP signing data is adjusted to realize that each piece of PDP signing data can be inserted and used, so that the utilization rate of the PDP signing data received by the SGSN reaches one hundred percent.
Generally, the SGSN is registered in the HLR, and if the SGSN is not registered, all PDP subscription data may be directly inserted as it is according to the conventional technique.
Step S104: and inserting the corrected PDP subscription data to the SGSN.
In summary, after receiving the data service request, the HLR determines the PDP support capability of the SGSN and the PDP subscription data of the requesting party, and adjusts the PDP subscription data to be supported by the PDP support capability of the SGSN, thereby avoiding issuing unusable PDP subscription data to the SGSN, saving the storage space of the SGSN, and improving the efficiency of the SGSN in processing the PDP subscription data.
Please refer to fig. 3, which is a flowchart illustrating a method for dynamically adjusting pdp subscription data during roaming according to a second embodiment of the present invention. As shown in the figure, the interaction method includes:
step S201: a data service request initiated by a terminal via a serving general packet radio service support node SGSN is received.
Step S202: and acquiring the Packet Data Protocol (PDP) subscription data of the terminal, and acquiring the PDP support capability pre-registered by the SGSN.
Step S203: when the SGSN only supports IPv4, the PDP subscription data is of non-IPv 4 type, adjusted to IPv4 type.
Step S204: when the SGSN supports IPv4 and IPv6, the PDP subscription data is of dynamic IPv4v6 type, adjusted to IPv4 type.
In the actual adjustment process, in addition to the adjustment schemes in step S203 and step S204, a more detailed adjustment scheme may be adopted, which specifically includes:
when the SGSN only supports IPv4, the PDP subscription data is static IPv6 type or static IPv4v6 type, and the PDP subscription data is deleted;
when the SGSN only supports IPv4, the PDP subscription data is of a dynamic IPv6 type or a dynamic IPv4v6 type, and is adjusted to be of an IPv4 type;
when the SGSN supports IPv4 and IPv6, the PDP subscription data is converted into two pieces of PDP subscription data in a dynamic IPv4v6 type, wherein the two pieces of PDP subscription data are respectively in an IPv4 type and an IPv6 type;
when the SGSN supports IPv4 and IPv6, the PDP subscription data is static IPv4v6 type PDP subscription data deleted.
Step S205: and if the newly added PDP subscription data after the correction is the same as the original PDP subscription data, deleting the newly added PDP subscription data.
If a more detailed adjustment method is adopted, the number of the PDP subscription data changes, and if the newly added PDP subscription data is the same as the original PDP subscription data, the retention of the newly added PDP subscription data causes the repetition of the PDP subscription data, and for such repetition, in order to reduce the storage utilization rate and the data efficiency, the newly added repeated PDP subscription data is deleted.
Step S206: if the total number of the corrected PDP subscription data exceeds the number of the PDP subscription data allowed to be inserted, the original PDP subscription data is reserved, and the newly added PDP subscription data is partially reserved.
According to the 3GPP protocol, each subscriber can subscribe to a maximum of 50 PDP subscriptions, which are stored in the HLR, which is transferred to the SGSN when the subscriber registers in the GPRS/UMTS PS domain network. Correspondingly, if the total number of the adjusted PDP contract data exceeds the upper limit of 50, the number of the PDP contract data needs to be adjusted, and all the original PDP contract data needs to be retained first, and the newly added PDP contract data needs to be partially retained. The newly added PDP subscription data may be specifically reserved in time sequence or randomly.
Step S207: and inserting the corrected PDP subscription data to the SGSN.
As shown in fig. 4 in particular, when a user needs to use a data service, a PDP activation procedure is triggered. The handset sends the device capabilities to the SGSN according to the user's instructions (step 1 in the figure). After SGSN receives user request, it will select proper PDP signing data according to the carried ability of the device, SGSN ability and signing data sent by HLR, and sends connection establishing request to GGSN (step 4)
In summary, after receiving the data service request, the HLR determines the PDP support capability of the SGSN and the PDP subscription data of the requesting party, and adjusts the PDP subscription data to be supported by the PDP support capability of the SGSN, thereby avoiding issuing unusable PDP subscription data to the SGSN, saving the storage space of the SGSN, and improving the efficiency of the SGSN in processing the PDP subscription data. The further limited PDP signing data adjustment mode ensures the corresponding adjustment of various types of PDP signing data; and the processing of the adjusted PDP subscription data ensures that the adjustment normally operates under the system rule.
