Description

A method and device for deactivating PDP context

technical field

The invention relates to the field of wireless communication, in particular to a method and device for deactivating a PDP context in a GPRS or WCDMA system.

Background technique

The network structure of the GPRS or WCDMA system is shown in Figure 1, including the radio access network UTRAN and the core network CN, where the radio access network handles all wireless-related functions, while the core network handles all voice calls and data connections in the system, And realize the switching and routing functions with the external network (External Network). The UE is user equipment, which performs data interaction with the wireless access network, and provides users with various service functions in the circuit domain and packet domain.

Subdividing the UE can be divided into two parts: TE and MT. TE is a specific application module, including a specific application program APP, and MT is a communication interface module. TE is connected to the wireless access network through MT. The interface between TE and MT is R interface. AT command provides a set of standard command words, enabling communication between TE module and MT module, such as telephone service, short message service, etc.

In the current AT command, the deactivation (deactive, turning the activation state into an inactive state) PDP (Packet Data Protocol, packet data protocol) context processing command is the CGACT deactivation command (AT command is the general name of multiple commands, CGACT The command is one of them, and the CGACT command is specifically divided into a CGACT activation command and a CGACT deactivation command, etc.), according to the requirements of the agreement, after entering the relevant deactivation parameters in the user device, a CGACT deactivation command is generated, and then a deactivation command is generated. PDP context message, the network side can deactivate the specified PDP context according to the deactivation PDP context message. For the convenience of understanding, the PDP context can be understood as equivalent to a software module. A PDP context has a The parameter CID, so a specific PDP context can be represented by CID, for example, two different PDP contexts can be represented by CID1 and CID2, and multiple PDP contexts can share one PDP address.

Specifically, when deactivating all PDP contexts that use the same PDP address as the specified PDP context, since the user does not know in advance which PDP contexts share a certain PDP address, the user equipment needs to use the application program on the TE to first query out All PDP contexts that use the same PDP address as the specified PDP context, then generate a CGACT deactivation command according to the CIDs of these found PDP contexts, and then generate a deactivation PDP context message according to the CGACT deactivation command, and then the core network according to the specified The deactivation PDP context message deactivates these PDP contexts. For example, when deactivating all PDP contexts (including CID1) that use the same PDP address as CID1, first query the PDP address of each PDP context (including CID1) in the user equipment, and obtain the PDP context using the same PDP address according to the query result. PDP contexts such as CID2 and CID3, and CID2 and CID3 are added to the CGACT deactivation command, and then a deactivation PDP context message is generated according to the CGACT deactivation command and sent to the network side, and the network side executes the corresponding deactivation PDP context message according to the deactivation PDP context message Deactivate the action.

Due to the limitation of the existing AT command function, when the user equipment side generates the deactivation PDP context message, a message will be generated for each PDP context that is inquired, and the network side will receive multiple messages, and Each message must be executed, that is to say, a deactivation process must be performed for each PDP context that uses the same address during the deactivation operation, so it is necessary to perform multiple deactivation processes, and one deactivation process requires multiple Signaling interaction between secondary devices, including inside the core network, inside the access network, inside the user equipment, and between the user equipment and the core network through the wireless access network, thus resulting in a slow response speed of the communication system and reducing the communication speed. equipment efficiency.

Detailed ways

In order to solve the problem that in the prior art, when the network side deactivates, each PDP context that uses the same address needs to perform a deactivation process, resulting in low usage efficiency of the communication device, the embodiment of the present invention can be understood as Set the corresponding content in the process of deactivating the PDP context message, and the content is used to notify the core network to deactivate all eligible PDP contexts in one deactivation process, that is, use the same PDP address as the specified PDP context and be in the activated state Correspondingly, after receiving the deactivation PDP context message, the core network directly deactivates all PDP contexts that use the same PDP address as the specified PDP context and are in an activated state according to the content.

When the embodiment of the present invention performs the deactivation operation in the core network, it mainly includes the following steps:

receiving a deactivation PDP context message sent by the user equipment, where the deactivation PDP context message includes a specified PDP context;

Judging whether the deactivation PDP context message requires deactivation of all PDP contexts that use the same PDP address as the specified PDP context and are in an activated state;

If so, search for all PDP contexts that use the same PDP address as the specified PDP context and are in an active state;

Deactivating all found PDP contexts that use the same PDP address as the specified PDP context and are in an active state, including the specified PDP context.

Correspondingly, when the present embodiment generates the deactivation PDP context message in the user equipment, it mainly includes the following steps:

Receive a CGACT command, and according to the first parameter that is used to represent the CGACT command type in the CGACT command, namely the state parameter, determine that the CGACT command is a CGACT deactivation command;

Judging whether the CGACT deactivation command includes a second parameter, the second parameter is used to indicate that the deactivation and the PDP context specified in the CGACT deactivation command use the same PDP address and are all PDP contexts in an active state;

When it is determined that the CGACT deactivation command includes the second parameter, generate a deactivation PDP context message;

And indicate in the deactivating PDP context message to deactivate all PDP contexts that use the same PDP address as the PDP context included in the message and are in an activated state.

In the embodiment of the present invention, when it is determined that the CGACT deactivation command requires deactivation of all eligible PDP contexts, that is, all PDP contexts that use the same PDP address as the specified PDP context and are in an active state, the deactivation PDP context message generated The type of the deactivation operation indicated in is: deactivate all activated PDP contexts that use the same PDP address as the specified PDP context; after receiving the deactivation PDP context message, the core network finds out all eligible PDP contexts according to the indication Deactivate the PDP context directly. In this embodiment, all eligible PDP contexts can be deactivated in one deactivation process, which avoids the need to perform a deactivation process when each PDP context is deactivated in the prior art, resulting in low usage efficiency of communication devices. question.

The specific implementation process of this embodiment will be further introduced below.

Please refer to Table 1, the CGACT command provided by the embodiment of the present invention in Table 1, the command can contain multiple specified PDP contexts, and when the CGACT command requires deactivation of all eligible PDP contexts, it can be realized by adding parameters. Compared with the existing CGACT command, the CGACT command provided by the embodiment of the present invention adds a tear down parameter, and the meanings of other parameters remain unchanged. Among them, <state> is used to indicate the activation state of the PDP context. When the state value is 0, it means that the message is used to deactivate the PDP context; when the state value is 1, it means that the message is used to activate the PDP context; here, the state parameter is used as The first parameter, tear down parameter as the second parameter.

<tear down> means to deactivate all active PDP contexts using the same PDP address. When the tear down parameter is "N", it means that only the PDP context corresponding to the specified CID is deactivated; when the tear down parameter is "T", Indicates to deactivate all activated PDP contexts with the same PDP address as the specified PDP context; if the <tear down> parameter is not filled, the default is to deactivate only the PDP context corresponding to the specified CID. Of course, the tear down parameter can also be set to 0 or 1 to indicate that only the PDP context corresponding to the specified CID is deactivated or all activated PDP contexts with the same PDP address as the specified PDP context are deactivated.

Table 1 New CGACT command syntax

Order possible response +CGACT＝[<state>[,<cid>[,<teardown>][,<cid>[,<tear down>][,...]]]] OK ERROR +CGACT? +CGACT:(cid>.<state>[<CR><LF>+CGACT:<Cld>,<state>[...]] +CGACT=? +CGACT: (list of supported<state>s)

Please refer to FIG. 2, which discloses a specific process of deactivating the PDP context in the embodiment of the present invention.

(1), the specific application module in the user terminal generates the CGACT command comprising the tear down parameter;

When the specific application module generates a CGACT command, the command includes the state parameter and the CID of the specified PDP context. The specified PDP context can be one or multiple, and also includes the tear down parameter, and the specific selection of the tear down parameter The value can be determined according to the user's instruction. When the state parameter is 0, the CGACT command is a CGACT deactivation command.

(2), the specific application module sends the CGACT command including the tear down parameter to the communication interface module;

Step (1) describes how to generate the CGACT command including the tear down parameter, which is not difficult to implement according to Table 1 and the prior art.

(3), the communication interface module generates a corresponding deactivation PDP context message according to the CGACT command, and indicates deactivation in the message of all PDP contexts that use the same PDP address as the specified PDP context and are in an active state;

(4), the communication interface module sends the deactivation PDP context message to the core network through the wireless access network;

(5) After the core network receives the message sent by the user equipment, it analyzes that the message is a deactivation PDP context message, and the message requires deactivation of all PDP contexts that use the same PDP address and are in an active state. PDP context; and

(6), the core network finds out all PDP contexts that use the same PDP address as the specified PDP context and are in an active state, and deactivate these PDP contexts;

After step (6), it can also include:

(7), after completing the deactivation operation, the core network sends a deactivation completion message to the communication interface module in the user equipment;

(8), further, if there is a RAB (Radio Access Bearer wireless link bearer) between the core network and the user equipment before the PDP context is deactivated, the RAB release operation is performed between the core network and the user equipment, and this step has been It is disclosed in the prior art and will not be described in detail here.

(9) The communication interface module in the user equipment notifies the specific application module that the CGACT command has been executed.

Through the above description, the embodiment of the present invention can implement the deactivation operation for multiple PDP contexts in one deactivation process, effectively improving the use efficiency of the communication device.

Referring to Fig. 3, step (3) may specifically include:

Step 301, receiving a CGACT command;

Step 302, using the value of the state parameter included in the CGACT command to determine that the CGACT command is a CGACT deactivation command;

Step 303, judging whether the CGACT deactivation command includes the second parameter, namely the tear down parameter, if so, execute step 309;

Step 309, for each specified PDP context in the CGACT deactivation command, generate a deactivation PDP context message including the specified PDP context;

Step 310, instruct in each deactivate PDP context message to deactivate all PDP contexts that use the same PDP address as the PDP context included in the message and are in an activated state.

Specifically, when instructing, a specific information element (Information Element) can be set in the deactivation PDP context message, and it can be completed by setting a corresponding value of the specific information element, for example, setting it to 1.

If in step (1), the CGACT command generated by the specific application module in the user terminal does not include the tear down parameter, then in step 303 it will be judged that the CGACT command does not include the teardown parameter, and at this time the following steps can also be included (this Is it not the existing technology? Can it realize the purpose of the invention? Why introduce this? It is different from the existing technology, and it has an improvement on the existing technology):

Step 304, determining that the number N of PDP contexts specified in the CGACT deactivation command is greater than or equal to 2;

Step 305, querying the PDP address used by the specified PDP context;

Step 306, determining that there are M PDP contexts using the same PDP address according to the inquired PDP address, where M is an integer and greater than or equal to 2;

Step 307, generating a deactivation PDP context message for the M PDP contexts, and arbitrarily selecting a PDP context among the M PDP contexts as the specified PDP context in the deactivation PDP context message;

Step 308: Indicate in the deactivating PDP context message to deactivate all PDP contexts that use the same PDP address as the PDP context included in the message and are in an activated state.

In step 307, for the M PDP contexts, only one deactivation PDP context message may be generated, or multiple messages may be generated;

In addition, if one group of PDP contexts uses address IpAddr1 and another group of PDP contexts uses address IpAddr2, and IpAddr1 and IpAddr2 are different, then for these two groups of PDP contexts, only two deactivation PDP context messages can be selected.

Of course, after judging in step 303 that the CGACT deactivation command includes the second parameter, steps 304 to 308 can also be performed, and a deactivation PDP context message can be generated for those PDP contexts using the same PDP address (huh? If the second parameter is not included, the processing is the same? Why do we need the second parameter? The features of 304-308 can be applied to two situations: including the second parameter or not including the second parameter).

When instructing to deactivate all PDP contexts that use the same PDP address as the specified PDP context and are in the active state, you can set a specific information element in the deactivation PDP context message and set the value of the specific information element to 1. Implementation, the specific information element is used to indicate whether to deactivate all active PDP contexts using the same PDP address;

Step (5) may specifically include:

Step 51, the core network receives the message sent by the user equipment;

Step 52, confirming that the message is a deactivation PDP context message;

Step 53, judging that the message requires deactivation of all PDP contexts that use the same PDP address as the specified PDP context and are in an active state;

Step 53 may specifically include the following steps:

judging whether the message contains a specific information element, the specific information element is used to indicate whether to deactivate all PDP contexts that use the same PDP address as the specified PDP context and are in an activated state; and

When the message contains a specific information unit, it is further determined that the value of the information unit is 1.

In practical applications, the core network may receive multiple deactivation PDP context messages, and the messages all require deactivation of all PDP contexts that use the same PDP address as the specified PDP context and are in the activated state. If the PDP context specified in one or more messages uses the same address, then after executing one message, when executing another message below, it can be further judged that the PDP context specified in the other message is different from the one specified in the executed message. Whether the PDP context uses the same address.

If so, in step (6), you can choose to directly send a message that deactivation has been completed to the user equipment; if not, deactivate all PDP contexts that use the same PDP address and are in an active state with the PDP context specified in the other message. PDP context.

Further, in step (1), when the specific application module in the user equipment generates the CGACT deactivation command, it can also inquire whether the specified multiple PDP contexts use the same PDP address. When different PDP addresses are used, the CGACT deactivation In the activation command, different tear down parameters can be set for PDP contexts using different PDP addresses (this idea should be included in the essential method of this patent, it is not enough to add these two sentences, it will involve the whole method Changes, all alternatives, should be included in a superior method, and then the alternatives, and whether the alternative replaces the entire method, or a step, should be clear, Miao Miao, you are so good, sometimes a The change of the two features will lead to the change of the whole scheme. I have encountered this situation now. It can be said that it is further limited here to prevent possible conflicts when adding the teardown parameter) to indicate the execution of different deactivation Operation, for example, when CID1 and CID2 use different PDP addresses, you can choose to deactivate all active PDP contexts that use the same PDP address as CID1 and deactivate CID2.

In addition to Table 1, the CGACT command syntax can also be shown in Table 2,

Table 2 New CGACT Command Syntax

Order possible response +CGACT＝[<state>[,<cid>,[,<cid>,[,...]]]][,<tear down>] OKERROR

+CGACT? +CGACT:<cid>.<state>[<CR><LF>+CGACT:<cid>,<state>[...]] +CGACT=? +CGACT: (list of supported<state>s)

Compared with Table 1, the tear down parameter is placed at the end of the AT command, that is, after all specified PDP contexts. In addition, the tear down parameter can be placed before the first specified PDP context. These two different format meanings The same means that all specified PDP contexts are required to perform the same type of deactivation operation. At this time, if there are multiple specified PDP contexts and use different PDP addresses, for example, there are two specified PDP contexts CID1 and CID2, and When the IpAddr1 used by CID1 is different from the IpAddr2 used by CID2, either CID1 and CID2 are required to be deactivated, or all PDP contexts using IpAddr1 and all PDP contexts using IpAddr2 are required to be deactivated, but CID1 and IpAddr2 cannot be deactivated at the same time. All PDP contexts.
