The term "protocol" is intended to include any software, i.e., software provided to implement portions of any layer defined for communication.

The communication device (which may also be referred to as a terminal device) may be a wired communication device. The communication device may be a radio communication device.

Media configuration over IMS (IP (internet protocol) multimedia subsystem) can be complex (e.g., it may be desirable to handle multiple audio and video formats, service upgrade/downgrade, one-way/two-way). In case the user application and the IMS client are located on separate units (e.g. separate processors, such as a laptop and a modem), there is no standardized and easy way to use mechanisms to remotely configure the media to be applied by the IMS client at service set-up or service modification.

Services initiated over IMS may continue through traditional Circuit Switched (CS), or vice versa. During mobility with service continuity, media may be maintained or modified (e.g., downgraded or upgraded). To date, it has not been possible to globally describe media that includes transformations to be applied in the case of service domain modifications.

IMS communication service calls may be controlled via Session Initiation Protocol (SIP) and Session Description Protocol (SDP).

Fig. 1 illustrates an architecture 100 of a communication device, such as a mobile phone architecture. The mobile phone 102, which may also be referred to as T, may comprise a terminal equipment TE 104, a terminal adapter TA 106 and a mobile terminal MT 108.

A mobile terminal (MT; e.g. modem hardware comprising a sender and a receiver for inter-device communication) may also be referred to as a modem device, which may be controlled by a terminal equipment (TE; e.g. hardware interacting with a terminal user and comprising an application processor and means for user interaction) via AT commands.

AT commands may be used to control voice/data (e.g., video) calls to non-IMS services. The AT commands allow for determining the data rate and device class used by the ME (mobile device) to determine whether a video call should be set up on a legacy CS.

The new AT commands may be defined by 3GPP to be used by IMS services.

Disadvantages may be: existing AT commands may specify the specific media to be used by the IMS service; existing AT commands may specify the media quality of the IMS service; existing AT commands may not be available to configure media support for incoming calls; existing AT commands may not be available to control the media of an incoming call; existing AT commands may not allow reuse of media configurations for multiple IMS calls (e.g., if an IMS call is set up, a long parameter list of media configurations should be given. Existing AT commands may not allow for specifying media configuration by a single parameter; existing AT commands may not allow for partial modification of the media configuration (e.g., alternatively, the complete configuration may need to be provided for modification); no media profile can be provided independent of the technology (IMS or circuit switched) used to determine device behavior after service continuity or at call setup; in mobility usage scenarios, it may not be possible to control the media downgrade/upgrade after service continuity.

The profile may include parameter values for setting up the transceiver structure. A profile may be defined by the structure of the profile, which includes parameters to be set for the transceiver structure. The profile may then include parameter values that conform to the parameter structure.

Apparatus and methods may be provided for introducing concepts of media profiles, for example as follows:

the media profile may contain all information related to the media configuration;

-the media profile may contain information applicable to multiple technologies (IMS, CS) or conversion rules when moving from one technology to another; and

the media profile is persistent and reusable by subsequent call sessions.

When setting up or modifying a call session, a reference may be made to an already defined media profile. The media profile may also be given as part of the service command itself.

Using these devices and methods:

the indication for media configuration may be short;

the media configuration may allow for taking into account future additional parameters related to the media session description;

media is configurable for multiple technologies to facilitate service continuity in mobility scenarios;

the media configuration may be modified;

default and predefined media configurations may be defined;

the media configuration can be reused for subsequent call sessions;

the indication of the media configuration for the incoming call may be short;

the media profile may allow predefined behavior for incoming calls without requiring user interaction in determining which media configuration to accept/reject; and

the ongoing communication in case of a partial media profile modification may be modified to have a short indicator or to have a short data volume.

Devices and methods may be provided that introduce media profiles and use the media profiles to configure call sessions. The media profile may be modified. The media profile may be reused for multiple call sessions. A media profile may cover multiple technologies and corresponding media transitions in a mobility scenario.

A media profile may be introduced. The media profile may include all information related to the description of the media in the session, such as audio codec information, video codec information, codec preferences, required quality of service, media connection information (e.g. information indicating whether data is to be sent and/or received, e.g. port description). The content of the media profile may be expanded in the future to any new possible media configuration.

The media profile may provide information related to multiple technologies (e.g., IMS and legacy CS), such as:

for all technology-related media information, such as media type (audio, video);

-media information relevant for a specific technology. This can be defined for each technology. Depending on the technology used, the corresponding media description may be used; and/or

-transition rules in case of intersystem change (which may be a change from codec to automatic downgrade or upgrade of media services);

the media profile may be identified with a unique identifier. The reference may be used by commands (for setting up and modifying IMS or other services) to specify the media configuration to be applied.

The identifier of the media profile may:

-set by TE at media profile creation time; or

-indicating by the MT with a successful media creation response

Media profiles may be created, deleted, and modified. It may be persistent information that can be reused for subsequent call sessions.

New commands of the communication end terminal may be defined to create, retrieve, modify and delete media profiles. Additional commands may be defined to define or modify individual parameters of the media profile.

The media profile may be created either initially before setting up the call or directly with the service request command itself.

The predefined profile may be preset by the manufacturer.

A media profile may consist of two parts:

a static part, which can also be modified (on a long time scale);

-a dynamic part resulting from a media negotiation with the network, wherein the dynamic part may be deleted upon release of the call session.

For example, at least one of the following regarding media profile processing may be provided:

the media profile may be bound to one active call session. If the first session is still active, it may not be reused by the second call session. A second profile may be determined for a second call session running in parallel. The same identifier may be used to reference the call session and the corresponding media profile.

The media profile may be reused by multiple simultaneous call sessions. In this case, separate IDs may be used for the call session and for the media profile. In this case, the dynamic portion of the media profile may be defined per call session and may be referenced with a call session identifier.

The modification of the media configuration may be performed in different ways:

modification of the media profile itself may result in an immediate change of the media configuration of the active call. In this case, sending a command to modify the profile may result in a call modification.

The media profile may be updated independently of the active call session. In this case, a first command may be sent to modify the media profile. The media configuration of the active call may not be changed. Another command may be sent if the modified profile should be applied for an active call.

The media profile may be configured to be applicable only to outgoing calls, only to incoming calls, or both.

The media profile may be used to predetermine the behavior of the device for the incoming call. The media profile may be configured to list a range of allowed configurations for the incoming call. When a call is received, only media configurations allowed by the media profile will be accepted. The user or phone application may be limited to the range of allowed incoming call configurations. An example of such a use is a bluetooth headset or an in-car hands-free device. In these cases, the media profile may be configured to be applicable to incoming calls where video usage is disabled or configured in a receive-only mode. The user or the phone application will then only accept the call without having to be concerned with the media configuration.

Examples of media profile definitions will be described below.

The commands for configuring the media profile, the media attributes listed as parameters, will be described below.

As an example, the media configuration may be a pure string based on the SDP model, or a new string template may be defined if not overwritten by the SDP.

For example, the commands may be as follows:

+CDEFMP＝[<mediaparam1>,[<mediaparam2>...，[<mediaparamx>,[＜mediaparamy>,...]]]]

in this command, "+ CDEFMP" may be an identifier of the command, "mediaparam 1", "mediaparam 2", "mediaparamx", and "mediaparamy" may be parameters for defining a profile.

For example, for a 3G video call, a new string may be defined: for a video call (multimedia) at 28800bps on CS, "mod 130".

As an example, some structures may be given in the media profile definition command. The command may be based not only on a character string.

For example, the commands may be as follows:

+CDEFMP＝[<mediaList>,[<mediaType>,<dom>,<paramList>,

[<mediaparam1>,[<mediaparam2>…]]],[<mediaType><dom>,

<paramList>,[<mediaparam1>,[<mediaparam2>…]]]

< mediaList > (< media list >) may be or may include an integer and may indicate a plurality of configured media types.

< mediaType > (< media type >) may indicate the type of media (audio, video, text …) and may use, for example, the following values:

-0 for audio;

-1 for video; and

-2 for text.

< dom > may be or may include integer (or enumeration) and may indicate a domain of media applicability (e.g., generic, technology specific, default), and may use, for example, the following values:

0 for general purpose (e.g. applicable to all technologies if support is available);

-1 for legacy CS (circuit switched);

-2 for GSM (global system for mobile communications) CS;

-3 for UMTS (universal mobile telecommunications system) CS;

-4 for IMS (internet protocol multimedia subsystem);

-5 IMS over HSPA (high speed packet access);

-6 for IMS over LTE (long term evolution); and

-7 for default: the minimum configuration is the case if the common configuration is not supported in the current technology.

< paramList > (< parameter list >) may be a number of media configuration parameters for the dedicated media type.

The response to the command may indicate that the media profile identifier ID: + CDEFMP: < ID >

With respect to the media configuration < media param > itself, several alternative ways for configuring media parameters are possible:

or the media profile may be based on a direct SDP sequence, e.g.:

< media > < media > < media >, where < media > < media > is an SDP description: m- …, a- …

For example: an audio call with 16-bit linear encoded stereo audio sampled at 16kHz may be represented by:

+CDEFMP＝”m＝audio 49232RTP/AVP 98”,“a＝rtpmap:98L16/16000/2”

or each parameter can be described individually and independently of SDP, for example:

<media type>:

-1: audio

-2: video;

-3 text

< media format >:

- < codec > (< codec >) < enumeration of codecs

-…

- < clockrate > (< clock rate >):

-…

< Port > (< Port >) < value, Range (string)

< protocol >):

-1:UDP

-2:RTP/AVP

-3:RTP/SAVP

-…

< bandwidth >

< mode > (< mode >):

-1: transmission/reception;

-2: receive only;

-3: transmit only.

……

For example, a parameter of a media type

<audio><port＝49232><protocol＝RTP/AVP><codec＝L16><clock

The parameter of rate 16000> may be included in the following command:

+CDEFMP＝1,”49232”,2,22,”16000”

the media parameter may be either a fixed value or a list/range of supported values.

The command to get the list of the currently defined media profiles may be as follows:

+CDEFMP？

the return value may be either a list of identifiers or a complete profile definition (using the format described above).

The command to obtain the ME capabilities may be as follows:

+CDEFMP＝？

this command may allow retrieval of all media configurations supported by the ME. The return value may include or may be a range of supported media configurations.

The commands for obtaining the definition of the profile may be as follows:

+CDEFMP＝[<ID>]

the commands for modifying the profile may be as follows:

+CDEFMP＝[<ID>,[mediaList],[<mediaType>,<dom>,<mod>,[…]]]]

< mod > may indicate whether a given media configuration is added, modified, or removed:

-1 addition of media configuration

-2 modification of media configuration

-3 removal of media configuration

As an example, the video portion may be modified for a profile with identifier 2 by the following command:

+CDEFMP＝2,1,1,0,1,[…]

commands for modifying the specific parameters of the profile may be defined.

A specific AT command may be defined to modify some specific parameters such as audio codec, for example as follows:

+CDEFMP＝[<ID>,<mediaType>,<dom>,<codec>]

fig. 2 shows a flow diagram 200 illustrating media profile configuration and profile reuse in subsequent calls. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. As shown in fig. 2, at 202 TE 104 may configure the media profile using a command + CDEFMP that includes the media description. In 204, the MT 108 may respond to the ID of the generated profile with + CDEFMP ═ 1 (which may represent an ID of 1). Then, at 206, the TE may simply indicate the identifier of the media profile to be used in the dial command (+ CDU) when the call is initiated. The ME may use the media configuration described in the given media profile when setting up the call. In 208, the call may continue. After the call release (e.g., via the + CHUP command in 210), if the user wants to initiate another call (e.g., a video call) to a different user but with the same media configuration, the TE may again send the dial command (+ CDU) with the identifier of the media profile in 212. The media may not need to be reconfigured.

How the media profile is modified to cause a change in the media configuration of the call will be described below.

Fig. 3A shows a flow chart 300 illustrating a first alternative for media profile modification and call modification. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. The MT 108 can immediately account for the modification of the media profile (#1, i.e., the profile with ID 1), and the MT 108 can apply the new media configuration to the active call. For example, media profile #1 may be modified by adding video by command 302. The MT 108 can modify the call according to the profile modification.

Fig. 3B shows a flow chart 304 illustrating a second alternative for media profile modification and call modification. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. The media profile may be modified but a subsequent command may be initiated by the TE to indicate when the change needs to be considered. For example, media profile #1 may be modified by adding video by command 306, MT 108 may not modify the call upon receiving command 308. TE 104 may consider the modified profile upon an explicit request, such as through command 308 sent by TE 104.

TE 104 may also modify the call by pointing to another profile. For example, the media profile may not be modified, but the TE may initiate a command to modify the call and point to another profile (e.g., profile # 2). The call may be modified according to the new profile.

Fig. 4A shows a flow diagram 400 illustrating the setup of a call using a technology-specific portion of a media profile based on domain selection. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. The media profile may be configured using technology specific configurations. For example, in 402 TE 104 may send a command to configure a media profile that includes video. The SDP description < m > video 49170/2RTP/AVP 31> is applicable over IMS, while the additional description < mod > video CS speed 130> is applicable over 3G CS video calls at 28800 bps. In 404, MT 108 may indicate the ID of the generated profile as a response to TE 104. This may also indicate that the MT is not encoding and decoding video media, for example, since SDP is provided. But may forward the video RTP packets to TE 104. TE 104 itself may encode and decode.

After the call origination in 406 by TE 104, MT 108 may perform domain selection to determine whether the call is performed over CS or IMS. The MT 108 may then apply a media configuration corresponding to the technology used to set up the call. For example, TE 104 may initiate services regardless of the technology used.

After the MT 108 receives the command 406, the MT 108 may perform domain selection, such as:

-if the call is set up on the CS, using the CS part of the profile: video calls 28800 bps; and

-if the call is set up over IMS, configuring the video call using the IMS part of the profile.

MT 108 can configure the media based on the technology used without additional information from TE 104.

Fig. 4B shows a flow diagram 406 illustrating multiple media configurations in the case of domain selection conflicts when there is no media profile concept. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. Fig. 4B shows the same use case as fig. 4A, but with a conventional command. The TE may configure and initiate the call over IMS only in 408 (e.g., TE 104 may desire to initiate a video call over IMS). TE 104 may reconfigure and initiate the video call in the CS domain if unsuccessful due to an intersystem change or any restrictions in MT 108 that do not allow the IMS call to be set up. In 410, the MT 108 may determine that a call over IMS is not established because the network does not support IMS voice or the UE does not support IMS voice over the current RAT. At 412, a KO signal may be transmitted to indicate this. This may indicate to TE 104 that the IMS call failed, and TE 104 needs to configure the fclas and bearer service type to initiate the video call over the 3G (third generation) CS domain. In 414, 416, 418, and 420, the CS video call may be configured. At 422, TE 104 may send a dial command for the CS call to TE 108. After that, the MT 108 can set up a video call over the CS domain.

Fig. 5 shows a flow diagram 500 illustrating media reconfiguration after an intersystem change. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. The call may originate over GSM over a legacy CS and continue at 502. Although video is configured in the profile, it may not be used because GSM does not support video calls. In 504, a communication device (e.g., UE) including the MT 108 may move to LTE coverage. Reverse SRVCC (single radio voice call continuity) may be performed at 506 and the call session may be transferred to the IMS. In 508, the MT1108 may directly enable the video after the inter-system change to IMS, since the video may already be configured in the media profile. No additional media configuration may be required. Very short interactions between TE 104 and ME 108 may be provided. Since the video can be configured in the media profile, the video is automatically started on the IMS. No interaction with TE 104 may be required. For example, the MT 108 may send an indication (+ CDUC) to the TE at 510 to notify that a media reconfiguration is to occur. The TE may confirm at 512 or may request to maintain the initial configuration. It may not be necessary to provide the media configuration again because it is already configured in the profile. At 514, the video call may continue over the IMS.

Fig. 6A shows a flow diagram 600 illustrating temporary media profile creation at an incoming call. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. A service request (e.g., an incoming call) may arrive at the MT 108 at 602. In 604, a temporary media profile (e.g., a dynamic portion of the media profile) may be created. Fig. 6A may illustrate a case where MT 108 indicates an incoming call to TE 104 by commanding + CINU at 606. In the incoming call indication, an identifier of the created media profile may be given. For example, a media profile or multimedia configuration may be given. TE 104 may then modify the media configuration when modifying the media profile (e.g., before accepting the call or later during the call session).

For devices without a touch screen or in bluetooth headset use or similar use cases, it may be difficult to provide multiple options for acceptance of the call. If the device provides a single button/key to accept a call, the user may not be provided with the possibility to modify the media configuration of the incoming call. In this case, the media profile may be configured in advance to indicate what is the allowed media configuration. The MT may then decide which media configuration to apply for the incoming call based on the media profile. Thus, the user task is limited to accepting incoming calls and the user does not need to handle the modification of the media configuration.

Fig. 6B shows a flow diagram 608 illustrating an incoming call with a predefined media profile. The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. In 610, a bluetooth headset may be plugged in, or "in-car" use may be initiated, or a single button device may be present. In 612, TE 104 may send a command to configure a media profile with media capabilities allowed for the incoming call, e.g., video call capabilities may be limited to receive only. At 614, the MT 108 may respond with the ID of the generated profile. In 616, the incoming call may reach the MT 108. At 618, MT 108 may report the incoming call to TE 104, including an identifier of the appropriate profile. In 620, the user may simply press accept and the media configuration may be processed by the MT 108 based on the media profile. At 622, TE 104 may send an OK signal indicating user acceptance. At 624 the MT 108 may accept the call but only allow video in receive mode as described by the profile and may send a corresponding 200OK signal at 626.

Fig. 7 shows a flow chart 700 illustrating a list of predefined profile(s) and currently configured profile(s) for an MT (mobile terminal). The information flow between the terminal equipment TE1 (e.g. TE 104 of fig. 1) and the mobile terminal MT1 (e.g. MT 108 of fig. 1) is shown. The query command 702 as described above may be used to request a list of configured media profiles in the MT. This can be either a profile preset by the MT or a profile(s) configured by the TE. In 704, the MT 108 may provide (or notify) a pre-set profile based on its capabilities (e.g., one for voice calls and one for video calls). In other words, according to fig. 7, TE 104 can retrieve the predefined profile (if any) in MT 108.
