Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of packet data protocol establishment of connection method and device thereof.
Background technology
At global system for mobile communications (GSM, Global System for Mobile Communication)/GPRS (GPRS, General Packet Radio Service)/ enhanced data rates (EDGE that GSM uses, Enhanced Data rates for GSM Evolution) epoch, the downstream rate of network in theory at 8Kbps between the 100Kbps, and actual network downstream rate also is subjected to the restriction of various environment and condition, is difficult to reach theoretical value.Under so low network rate; carry out access to netwoks and all still feel difficult; therefore; in the GSM/GPRS/EDGE epoch; do not exist and set up a plurality of packet data protocol (PDP simultaneously; Packet Data Protocol) demand of Lian Jieing adopts the data card with a PDP passage usually, sets up PDP for a kind of business and connects; particularly; when business is initiated, be this business setting APN (APN, Access Point Name) and connection protocol; dial corresponding service number then; for example be * 99#, by the PDP passage of this data card, foundation is connected with the PDP of access network; the based on network ability of network side meeting; automatically be this traffic assignments speed, when this business is carried out, can take the whole bandwidth of network usually.
Along with networks development, TD SDMA inserts (TD-SCDMA at present, TimeDivision-Synchronous Code Division Multiple Access) downstream rate of network has reached 384Kbps, the time division high speed downlink grouping inserts (TD-HSDPA, Time Division-High SpeedDownlink Packet Access) flank speed of network can reach 2Mbps, like this high network rate is set up when guaranteeing that two or more PDP connect network support is provided; And the appearance of more and more data services has greatly been enriched PDP and has been connected pairing upper layer application.
Yet, have only a PDP passage in the present data card usually, only can set up a PDP at any one time and connect, so initiating second when professional, can only interrupt first professional corresponding PDP earlier and connect, abdicate the PDP passage, could set up second professional corresponding PDP and connect.The above-mentioned this PDP of foundation ways of connecting will be brought following shortcoming: 1, carrying out second when professional, needing to interrupt earlier first business, thereby causing the interruption of first business; 2, when the PDP that sets up second business connects, need to disconnect first professional PDP earlier and connect, this will expend the regular hour, if the user need often carry out the operation of multiple business, will waste a large amount of time of user; 3, when the user in access mailboxes or when carrying out some electronic commerce affair, because next professional arrival, when need interrupting current connection, so after next business is finished, when the user wants to continue access mailboxes or proceeds electronic commerce affair, may need to land again mailbox or e-commerce platform, thereby bring worse experience to the user; 4, under present TD-SCDMA/HSDPA network environment, carrying out second when professional, need to interrupt earlier first business, the PDP connected mode of this serial makes not high for the utilance of network.
In addition, though data card has also obtained certain development in recent years, develop into from single PDP passage and to have a plurality of PDP passages.Yet, when connecting, set up a plurality of PDP also remarkable parallel that a plurality of PDP connect that be equal to, when setting up a plurality of PDP simultaneously and connect, how to guarantee that upper-layer service can select PDP passage correct in the data card, and how to be these a plurality of traffic assignments speed, be present problem demanding prompt solution.Such as, the data card that employing has a plurality of PDP passages is that multiple business is when setting up PDP and connecting, when first professional arrival, because a plurality of PDP passages are arranged in the data card, dial corresponding service number so connect method for building up according to existing P DP, for example behind the * 99#,, can set up PDP for this business and connect by a PDP passage of giving tacit consent in this data card; And after * 99# was dialed in second professional arrival, the PDP passage of still attempting by this acquiescence was that second business set up the PDP connection, yet because the PDP passage of this acquiescence has been taken by first business, connected so can not set up PDP for second business; And suppose that this second PDP connects and can set up, because when setting up the PDP connection for first business, network can be the higher speed of this traffic assignments according to the ability of self, when this first business is carried out, can take the whole bandwidth of network usually; When second professional arrival, because network has not had bandwidth can distribute to this business, second PDP connection also can not really be set up in fact, thereby can not realize setting up when a plurality of PDP connect so.
In sum, there is not the scheme of setting up a plurality of PDP connections simultaneously in the prior art.

Embodiment
It is when business is initiated that the packet data protocol that the embodiment of the invention proposes connects the scheme of setting up, and chooses a unappropriated PDP passage from data card, by this PDP passage, to the speed that this professional this service request of access network application is provided; Access network is a traffic assignments speed based on this rate request, and by this PDP passage of choosing, sets up connecting by professional PDP.
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
The packet data protocol that Fig. 1 proposes for the embodiment of the invention connects the schematic flow sheet of method for building up, and concrete process description is as follows:
Step 11: end side packet data protocol establishment of connection device from the data card with at least two packet data protocol passages, is chosen a unappropriated packet data protocol passage when current business is initiated;
Concrete system of selection has multiple, has given the mode that three kinds of selections below:
Mode one, based on each packet data protocol passage in the data card and corresponding relation that each is professional, choose in the unappropriated packet data protocol passage of this data card a professional corresponding packet data protocol passage of this initiation.
In this selection mode, each PDP passage in the pre-configured data card and the corresponding relation that each is professional when business is initiated, are selected getting final product by a professional unappropriated PDP passage.
Mode two, based on each packet data protocol passage ordering in advance in the data card, choose in the unappropriated packet data protocol passage of this data card a packet data protocol passage of ordering sequence number maximum/minimum.
In this selection mode, be unique numbering of each PDP channel allocation in the data card in advance.When specifically choosing, can adopt the lowest number precedence method, promptly choose the minimum PDP passage of current unappropriated numbering; Also can adopt maximum numbering precedence method, promptly choose the maximum PDP passage of current unappropriated numbering.
Mode three, based on each packet data protocol passage ordering in advance in the data card, obtain the packet data protocol serial number of channels that is taken by the last business of the business of this initiation; Choose in the unappropriated packet data protocol passage of described data card, the ordering sequence number is not less than in the packet data protocol passage of the described sequence number of obtaining, a packet data protocol passage of ordering sequence number minimum.
This selection mode is also referred to as next passage precedence method, similarly, is unique numbering of each PDP channel allocation in the data card in advance.When new PDP connection requirement, obtain the last PDP serial number of channels of using, choose the next unappropriated PDP passage bigger than this sequence number of obtaining.Adopt this selection mode, can make balanced use of each PDP passage energy quilt in the data card, avoid frequently using same passage that hardware is caused damage.
Step 12: end side packet data protocol establishment of connection device is determined this business institute rate request based on predetermined strategy;
For fear of existing when setting up PDP and connecting, network side directly is the higher speed of this traffic assignments, make when this business is carried out, take the whole bandwidth of network, thereby cause to set up the problem that many PDP connect simultaneously, in the PDP establishment of connection scheme that the embodiment of the invention proposes, end side possesses the ability of the speed that can determine service request, the mode of the speed of concrete definite service request has multiple, for example: the speed of supporting based on data card in advance, set up the number that PDP connects simultaneously, for waiting to set up the ratio that each professional default this business institute rate request that PDP connects accounts for the speed that data card supports, thereby can determine each professional institute rate request.Supposing to set up simultaneously two PDP connects, one is the PDP connection of business of networking correspondence, one is the PDP connection of MMS correspondence, the maximum that each professional institute rate request takies the ratio of data card supporting rate is set, business of networking institute rate request for example is set occupies 90% of data card supporting rate, MMS institute rate request occupies 10% of data card supporting rate, and based on the minimum value 384Kb/s of data card supporting rate, the maximum that can determine to carry out business of networking institute rate request is 384 * 90%=346Kb/s, and carrying out the maximum rate that MMS asks is 384 * 10%=38Kb/s.

Step 14: access network is this traffic assignments speed based on this rate request; And, set up connecting by professional packet data protocol by the described packet data protocol passage of choosing;
After network side received the speed of this service request, according to network condition at that time, the speed that is no more than this rate request for one of terminal distribution was given the user.For example network side is if judge and currently have sufficient bandwidth to distribute, so just to this rate request of traffic assignments of this request; If network side is judged the speed that current network bandwidth is not enough to distribute to this business described request, so just to speed of traffic assignments of this request less than this rate request.If the remaining bandwidth of current network is less certainly, be that requested service distributes less speed based on this less remaining bandwidth, when this speed can not guarantee that business is normally carried out, network side can be refused to set up to connecting by professional PDP.
Step 15: at the packet data protocol passage by choosing, set up after the packet data protocol connection that should be professional, this packet data protocol passage of end side packet data protocol establishment of connection device recording is taken by this business.
Access network is after the PDP that sets up corresponding initiation business by the PDP passage connects, and the business that this PDP passage of end side packet data protocol establishment of connection device recording is initiated takies, with the foundation as selector channel in the step 11.
